Social Media, Data Mining & Machine Learning

List of Social Tagging Datasets

2009-12-06T10:47:00.002+01:00

Markus Strohmaier is compiling a list of social tagging datasets available for research. Actually the list contains 8 datasets, but it's being actualized according to the comments made on Markus' blog. It seems a good place to find interesting datasets to work on, and also to share the actual datasets we're working on.

From Search to Recommender Systems

2009-12-03T11:10:00.002+01:00

Tech-companies rule the Web, and you can see that analyzing some of the biggest Internet companies like Google and Amazon. Google is the Intelligent Systems reference company due to their search engine, but also for the big quantity and quality of different technologies tehy develop like automated translation, user profiling, context management or even image processing.

Amazon is a e-commerce store, and it seems not so correlated with technology as Google, but the vision of Jeff Bezos and their commitment to technology have allowed them to grow like anyone before in the e-commerce market. For Bezos, an online store should not limit their catalog to a few items, online stores should contain millions of products, and should personalize the user experience of their users. His vision was clear: "if you have 3 million customers in the Web, I should have 3 million online stores", and then the recommender system ruled Amazon.

Both technologies (search and recommender systems) are useful for the Information Overload problem we suffer nowadays. But they're radically different from their conception. Search engines need the users to express their needs in textual form, and then process that query and retrieve the most relevant documents according to that query. Recommender Systems analyze the behaviour (and other kind of data) of the user in a website and then are able to choose the products or contents more likely to interest the user. Both approaches are useful, but until the moment recommender systems are not as popular as search engines.

But we are in a turnaround in the Web, as the way information is generated and consumed has changed. Nowadays, due to the success of Social Media sites like Facebook or Twitter, and even to the success of previous technologies as RSS, we receive a lot of information in a passive way: we don't ask directly to receive that information, but we receive it. Until the moment, the problem was to find some important information, but now the problem is turning into choose what information I already receive is relevant to me. That's why I think recommender systems will replace in popularity to search engines in the future.

1st Spring School on Social Media Retrieval (S3MR)

2009-11-08T23:03:00.001+01:00

DEADLINE: November 17, 2009.

Multimedia content has become ubiquitous on the web, creating new challenges for indexing, access, search and retrieval. At the same time, much of this content is made available on content sharing websites like YouTube or Flickr, or shared on social networks like Facebook. In such environments, the content is usually accompanied with metadata, tags, ratings, comments, information about the uploader and their social network, etc.

Analysis of these "social media" shows a great potential in improving the performance of traditional multimedia information analysis/retrieval approaches by bridging the semantic gap between the "objective" multimedia content analysis and "subjective" users' needs and impressions. The integration of these aspects however is non-trivial and has created a vibrant, interdisciplinary field of research.

The Spring School on Social Media Retrieval aims at bringing together young researchers from neighboring disciplines, offering

(1) lectures delivered by experts from academy and industry providing a clear and in-depth summary of state-of-the-art research in social media retrieval,

(2) collaborative projects in small groups providing hands-on experience on integrative work on selected problems from the field.

Scope

* Content distribution over social/peer-to-peer networks
* Multimedia content analysis
* Automatic multimedia annotation/tagging
* Multimedia indexing/search/retrieval
* Implicit media tagging
* Social data analysis
* Collaborative tagging

Confirmed lecturers:

-Susanne Boll, Carl von Ossietzky Universität, Oldenburg, Germany , http://medien.informatik.uni-oldenburg.de/personen/susanne_boll/

CFP: Special Issue of International Journal of Electronic Commerce on Mining Social Media

2009-10-30T11:49:00.003+01:00

After the experience of organizing the 1st International Workshop on Social Media (papers now online), we've been organizing a special issue of the IJEC (International Journal of Electronic Commerce) on Mining Social Media. Now we release the CFP hoping to receive high quality papers on Mining Social Media:

OVERVIEW

Recently, Forrester published a report, “The Future of the Social Web” where they sketched a timeline of the development of the Social Web, dividing its evolution in 5 eras. According to that report, the first era of the development of the Social Web started to explode the social relationships among users. Then, in the social functionality era, these social relationships resulted in the social functionality era where several websites started to add social functionalities in order to help users to interact with their peers. We are now in the era of Social Colonization, where technologies like Facebook Connect or Google Friend Connect have standardized social functionalities among websites and a vast majority of websites now include several social functionalities. Soon these federated identities will empower people to enter the era of social context with personalized and social content, and the development of tools for personalize social content will aim the development of the era of social commerce.

The primary goal of the proposed special issue of International Journal of Electronic Commerce is to foster research in the interplay between Social Media, Data Mining and Electronic Commerce, trying to reflect the actual developments on technologies that fit on the Social Context era.

SCOPE

The International Journal of Electronic Commerce is the #1-ranked journal on Electronic Commerce globally.

The Lemur Query Log Project

2009-07-29T13:12:00.002+02:00

Jose Maria Gomez has published in his blog about the Lemur Query Log Project, which is a very interesting iniciative leaded by Dr. Bruce Croft. The Lemir Query Log Project features a toolbar that collect queries and related navigation from users and send it to a database which collects a massive query log that may benefits the IR research community.

Information Retrieval, as most of the subdisciplines related to intelligent information access, relies on the availability of data, more specifically on testing datasets. That's the reason why projects like Lemur Query Log are so important for future researchs and developments.

Frauds in Science

2009-06-13T11:21:00.004+02:00

A month ago I wrote a post in my Spanish Intelligent Systems blog about frauds in science. In this post I resume what I wrote because I think it can be a good initial point for a debate about the present and future of Science.

Talking about frauds in science can be quite long, there are many little things in the actual scientific process that should be corrected (fake conferences, strange publishing processes, etc.), but I'll focus on big frauds,.

In August 2005, PLoS Medicine published "Why Most Published Research Findings are False", dealing with bad experimental design which conduces to wrong research findings. As stated in this paper, the scientific process is much focused in nobel research, and there is almost no support for research trying to replicate previous results, trying to corroborate previous findings.

In the paper "Repairing research integrity" published in Nature, June 2008, Sandra Titus and her team analyzes the integrity on scientific studies. Based on a survey over more than 4.000 researchers from over 600 institutiones, the results showed more than 200 cases of bad conduct in some scientific study, a number much higher than the registered previously by ORI (Office of Research Integrity). More than 60% of the total meant to data falsification, being plagiarism the next more usual bad conduct detected. Some of these frauds are detected on time, as the Kristin Roovers case, that was discovered by the editors of The Journal of Clinical Investigations when he sent a paper containing some images that had been manipulated with Photoshop.

There exists some regions where frauds are even a bigger problem. This is the case of China, where more than 60% of PhD students admit they have plagiarize some work. This represents a really big problem for China's research and even for the whole scientific community.

Recently, another big fraud in science was discovered, when The Scientist informed that Elsevier, one of the biggest scientific publishers, has several agreements with companiers to publish scientific journals that the companies use to promote their products. The first case detected was the Australasian Journal of Bone and Joint Medicine, where a paper was published promoting a product from Merck, a company that paid Elsevier for designing this journal. Summer Johnson writes about this big fraud in Bioethics, a really recommended lecture.

The scientific community must react to all these things, if we want to preserve the image of science but, what can we do? I think there are several options that could improve the scientific process:

1.- Open Access. The Elsevier case must make us to think that letting companies like Elsevier to control scientific publishing is not a good idea. Open Access seems a good way to prevent science from the desires and interests of big publishing companies. It is also a good way to assure an egalitarian access to scientific results.

2.- We should try to help iniciatives refering to negative results (or less important ones). Journals like Journal of Interesting Negative Results in Natural Language Processing and Machine Learning, Journal of Negative Results on Biomedicine, or Journal of Negative Results, are doing a good job publishing that kind of results.

3.- It also seems very important to improve working conditions of researchers. For instance, in Spain a lot of researchers earn less money that if they were working in a supermarket or driving a taxi, occupations with less responsabilities and less impact in the society. Who can care about doing high quality research if can't give his/her family a decent living?

4.- It is also needed to take up again scientific ethics. As researchers we must value what science word means. Science is not about publishing papers, science is all about improving the global knowledge, science is something really great.

Wikipedia Page Traffic Statistics for DataMiners

2009-06-13T10:43:00.002+02:00

Gregory Piatetsky pointed in KDnuggets Twitter account the release of a data package containing 7 months of hourly pageview statistics for all articles in Wikipedia. This dataset has a compressed size over 320 GB, over 1 TB uncompressed, and includes 7 months of hourly page traffic statistics for over 2.5 Million Wikipedia articles. All text content, statistics and link data in the dataset are licensed under GFDL (GNU Free Document License).

1st International Workshop on Mining Social Media

2009-05-06T00:21:00.001+02:00

I'm very glad to announce the MSM09 workshop that we are organizing in Sevilla (Spain), November 9. I hope to see some of you there :D

-------------------------------------------------------
CALL FOR PAPERS

1st International Workshop on Mining Social Media
http://www.socialgamingplatform.com/msm09/
Workshop at CAEPIA 2009 (http://www.lsi.us.es/caepia09)
November 9, 2009, Sevilla, Spain
Submission deadline: July 31, 2009
-------------------------------------------------------

OVERVIEW

Social Media are technological tools that allow users sharing and discuss information. Most Social Media are Internet based applications that manage textual information, as blogs (Blogger, Wordpress), microblogging (Twitter, Pownce), wikis (Wikipedia), forums, or Social Networks (Facebook, MySpace, LinkedIn). But there also exist other Social Media Internet applications where users share more than text, as photo sharing tools (Flickr, Picasa), video sharing (YouTube, Vimeo), livecasting (Ustream), or audio and music sharing (last.fm, ccMixter, FreeSound). More recent Social Media includes virtual worlds (Second Life), online gaming (World of Warcraft, WarHammer Online), game sharing (Miniclip.com) and Mobile Social Media like Nomad Social Networks where users share their current position in the Real World.

Social Media have been able to shift the way information is generated and consumed. At first, information was generated by one person and “consumed” by many people, but now the information is generated by many people and consumed by many people, changing the needs in information access and management. It is also noticeable that Social Media applications manage huge quantities of users and data: Facebook and MySpace manage between 100 and 150 million users, it is estimated that 1 million blog posts are generated each day, microblogging services like Twitter generates 3 million messages each day, YouTube manages more that 150.000 million videos, etc. All these points make clear that Social Media is an excellent application field for data miners.

CALL FOR PARTICIPATION

The Mining Social Media workshop aims to bring practitioners but also researchers with a specific focus on the application of existent or novel Data Mining techniques into the field of Social Media. We encourage the submission of experimental papers where Data Mining techniques are applied into existent Social Media, but also more theoretical papers that show clear application in real Social Media applications. The interesting topics include blog post analysis, blog comments analysis, blog spam, recommender systems for Social Media, clickstream analysis, relevance analysis, spam users detection, behavior analysis, contextual mining, Social Media user segmentation, route analysis for nomad Social Networks, multimedia mining, search in Social Media, etc.

All the submissions must be practical or theoretical applications of Data Mining or Information Management to Social Media (blogs, wikis, social networks, social services, e-mail, etc.).

The Socialization of the WWW

2009-04-23T15:22:00.002+02:00

This year, WWW2009 is being held in Madrid, a great event and a great place to celebrate the 20th Aniversary of the WWW. The WWW Conference is a great place to study the current opportunities and problems on the Web setup, and that’s why I use to read the abstracts of the accepted papers each years. And there is a visible evolution towards the Social Web in the last 3 years.

In WWW 2007 at Banff (Canada), there was no Social track, only a session called “Mining in Social Networks” under Data Mining track, were 3 papers were presented, but addressing Social Networks as a general paradigm of communication among people. WWW 2008 at Beining (China) had a Social Networks track, containing 3 sessions: “Analysis of Social Networks and Online Interaction Spaces”, “Discovery and Evolution of Communities” and “Applications and Infrastructures for Web 2.0”, and some other papers addressing Social Media as “Finding the Right Facts in the Crowd: Factoid Question Answering over Social Media”.

WWW 2009 clearly shows that the Web is Social. There exist a “Social Networks and Web 2.0” track addressing Social Media and Collaborative Web, with 4 sessions (Recommender Systems, Interactions in Social Communities, Difusion and Search in Social Networks and Photos and Web 2.0) and 12 papers, but there are also, at least, 5 papers in other tracks that address other relevant topics like privacy from a Social Media point of view:

“Learning to Recognize Reliable Users and Content in Social Media with Coupled Mutual Reinforcement”, from Graph Algorithms session
“What Makes Conversations Interesting? Themes, Participants and Consequences of Conversations in Online Social Media”, from Media Applications session
“Collective Privacy Management in Social Networks” from Web Privacy session
“To join or not to join: the illusion of privacy in social networks with mixed public and private user profiles” from Web Privacy session
“Emergent Semantics of Social Tagging” from Mining from Semantics

More than 12% of the papers accepted in WWW2009 are related to Social Media, and that’s a very good symptom of the Socialization of the Web.

Aware of Ranking Scam

2009-04-22T12:15:00.002+02:00

In the comments of a previous post, Jijung Tang links a very interesting information about online anonymous ranking sites. He points out some considerations about cs.conference-ranking.net and cs-conference-ranking.org. A must read post.

When I wrote the post about Conference Rankings, I didn't take care about who was behind cs-conference-ranking.org. I was said it was a good reference, and much of the conferences seem to be in a logical order. But Jijung is right, it's weird to find IAENG conferences among the most relevant conferences, and to hide the information about the creators of the ranking is not a good signal.

Social Media, Data Mining & Machine Learning

2009-04-22T11:58:00.003+02:00

I've been more than two months without updating the blog. A lot of work with my new company, trying to find funding for starting-up, and developing tons and tons of code lines. Now I'll try to update the blog once per week of once each two weeks, at least, but as my research interests have shifted a little bit to Social Media applications, I've decided to change the name of the blog from "Business Intelligence, Data Mining & Machine Learning" o "Social Media, Data Mining & Machine Learning". Probably the name of the blog is not so important, but working now on Social Media I feel more comfortable with that keywork in the title.

Information Access vs. Information Retrieval

2009-01-27T23:43:00.002+01:00

Jose Maria Gomez publishes a very interesting post about the differences of Information Access and Information Retrieval that are not so clear for a lot of people, including researchers of areas distant from IR or IA.

The Future of Social Networks

2009-01-08T12:50:00.000+01:00

Before Christmas, I wrote a post in my Spanish blog Sistemas Inteligentes (Intelligent Systems) containing some reflexions about the future of Social Networks. I try to resume the main idea and translate to English in this post, as I think Social Networks, and all Social Media are a really interesing field to KDD.

As stated by Wikipedia, "Emergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions. Emergence is central to the theories of integrative levels and of complex systems". Some strong ideas in AI are connected with emergence, like Swarm Intelligence that "is a type of artificial intelligence based on the collective behavior of decentralized, self-organized systems. The expression was introduced by Gerardo Beni and Jing Wang in 1989, in the context of cellular robotic systems".

But now, what does emergence have in common with Social Networks? For me there is a clear similarity: both emergent systems and social networks present a group of individuals interacting among them to form something bigger. In emergent systems that group of, let's say stupid or limited, individuals are able to connect among themselves to create some kind of cooperative organism that is more intelligent than the union of the intelligences of the individuals. In today's Social Networks (refering to the Social Networks applications like Facebook or MySpace) we have a really better initial state, we have a group of intelligent individual cooperating among them, but the result is not the expected, because the global information is just the union (or even less, as some information may be duplicated) of the information generated by each user. But it's even worse, the global intelligence of the system is almost null, as today's Social Network systems are all about information and are not trying to create a superior layer of the system by processing all that information and creating real knowledge.

For me, it's clear that the future of Social Networks is about developing systems that generates added value to the users by processing all the information and connexions. Next years, Social Networks will need to use KDD techniques and I'me sure Social Media will become the next big application field for KDD and Machine Learning.

CFP: 25th Conference of the SEPLN (Spanish Society for Natural Language Processing)

2008-12-18T16:52:00.003+01:00

September 8-10, 2009
Palacio Miramar, Donostia - San Sebastián
http://ixa2.si.ehu.es/sepln2009/

INTRODUCTION

The 25th edition of the Annual Conference of the Spanish Society for Natural Language Processing (SEPLN) will take place in the Miramar Palace in San Sebastian on September 8, 9 and 10, 2008.

We also expect to organise three satellite workshops during the week of the conference (see list of workshops).

The huge amount of information available in digital format and in different languages demands systems that enable us to access this vast library in an increasingly more structured way.

In this same area, there is a renewed interest in improving information accessibility and information exploitation in multilingual environments. Many of the formal foundations for dealing appropriately with these necessities have been, and are still being established in the area of Natural Language Processing and its many branches:

Information extraction and retrieval, Questions answering systems,
Machine Translation, Automatic analysis of textual content, Text
Generation, and Speech recognition and synthesis.

The aim of the conference is to provide a forum for discussion and communication where the latest research work and developments in the field of Natural Language Processing (NLP) can be presented by scientific and business communities. The conference also aims at exposing new possibilities of real applications and R&D projects in this field.

Moreover, as in previous editions, there is the intention of identifying future guidelines or paths for basic research and foreseen software applications, in order to compare them against the market needs. Finally, the conference intends to be an appropriate forum in helping new professionals to become active members in this field.

TOPICS

Researchers and companies are encouraged to send communications, project abstracts or demonstrations related to any of the following language technology topics:

Linguistic, mathematic and psycholinguistic models of language
Corpus linguistics
Development of linguistic resources and tools
Grammars and formalisms for morphological and syntactic analysis
Semantics, pragmatics and discourse
Lexical ambiguity resolution
Machine Learning in NLP
Monolingual and multilingual text generation
Machine translation
Speech synthesis and recognition
Monolingual and multilingual information extraction and retrieval
Question answering systems
Automatic textual content analysis
Text summarization
NLP-based generation of teaching resources
NLP for languages with limited resources
NLP industrial applications

STRUCTURE OF THE CONFERENCE

The conference will last three days, and will consist of sessions devoted to presenting papers, posters, ongoing research projects, prototype product demonstrations or products connected with topics addressed in the conference. Besides, we expect to organize three satellite workshops during the week of the conference.

SUBMISSIONS

The proposal must be submitted earlier than April 24, 2009 and they must meet certain format and style requirements.

Both the delivery and revision of proposals will be done exclusively in PDF electronic format via the Myreview system. We recommend using the LaTeX and Word templates that can be downloaded from the conference webpage.

Besides, the proposals will have to comply the following requirements, depending if they are communications, demos or projects.

COMMUNICATIONS

Full instructions for submission, including formatting guidelines and electronic templates for paper submission, are available on the IJCAI-09 website: http://www.ijcai-09.org (see the link titled Submission Details). Submitting authors will be required to register with the IJCAI-09 paper submission software (this will be linked from the IJCAI-09 website during the first week of December, 2008).

Papers may be accepted for either oral or poster presentation; papers accepted for either form of presentation will not be distinguished in the conference proceedings, nor will designation of oral or poster presentation be made on the quality of the contribution. Instead, these distinctions will be made in the interests of overall program coherence and quality.

To facilitate review, the paper title, author names, contact details, and a brief abstract must be submitted electronically by Jan. 7, 2009 (11:59 PST). No paper will be accepted for review unless an accompanying abstract is received by the deadline. Technical papers are due electronically on Jan. 12, 2009 (11:59 PST). Authors bear full responsibility for compliance with submission standards. Submissions received after the deadline or that do not meet the length or formatting requirements will not be accepted for review. No email or fax submissions will be accepted. Notification of receipt of the electronically submitted papers will be emailed to the designated contact author soon after receipt. If there are problems with the electronic submission, the program chair will contact the designated author by email. The last day for inquiries regarding lost submissions is Jan. 19, 2009. Notification of acceptance or rejection of submitted papers will be emailed to the designated author by March 31, 2009. The opportunity to respond to preliminary reviews will be made available to authors prior to this date, during the period March 13-16, 2009.

Guidelines for such responses, along with details of the reviewing process will be posted on the IJCAI-09 website. Camera-ready copy of accepted papers must be received by the publisher by April 14, 2009. Note: at least one author of each accepted paper is required to attend the conference to present the work. Authors will be required to confirm their acceptance of this requirement at the time of submission.

Authors who do not have access to the web should contact the program chair at pcchair09@ijcai.org no later than December 15, 2008 for alternate submission instructions.

Content Areas

To facilitate the reviewing process, authors will be required to choose two to four appropriate content area keywords from the list provided by the IJCAI-09 submission software, which will be part of the online paper registration process. Authors are encouraged to select the most specific keywords that accurately describe the main aspects of their contributions. General categories should only be used if specific categories do not apply or do not accurately reflect the main contributions. Each keyword is placed within one of ten 10 major themes; however, many of the keywords cut across multiple themes, and authors should feel free to select any keyword descriptive of the contribution, even if the major theme within which is it categorized is not the most appropriate. A list of keywords is appended to the end of this call.

The major themes are:

Agent-based and Multi-agent Systems
Constraints, Satisfiability, and Search
Knowledge Representation, Reasoning and Logic
Machine Learning
Multidisciplinary Topics And Applications
Natural Language Processing
Planning and Scheduling
Robotics and Vision
Uncertainty in AI
Web and Knowledge-based Information Systems

Policy on Multiple Submissions

IJCAI will not accept any paper which, at the time of submission, is under review for or has already been published or accepted for publication in a journal or another conference. Authors are also required not to submit their papers elsewhere during IJCAI's review period. These restrictions apply only to journals and conferences, not to workshops and similar specialized presentations with a limited audience and without archival proceedings. Authors will be required to confirm that their submissions conform to these requirements at the time
of submission.

Paper Length and Format

Submitted technical papers must be no longer than six pages, including all figures and references, and must be formatted according to posted IJCAI-09 guidelines. Specifically, papers must be formatted for "letter-size" (8.5" x 11") paper, in double-column format with a 10pt font. Electronic templates for the LaTeX typesetting package, as well as a Word template, that conform to IJCAI-09 guidelines will be made available at the conference website (see above) during the first week of December, as will further details on formatting.

Authors are required to submit their electronic papers in PDF format. Files in Postscript (ps), or any other format will not be accepted.

Submitted papers must not exceed six (6) formatted pages, including references and figures. This six-page limit will be strictly enforced: over-length papers will not be considered for review. Each accepted paper will be allowed six pages in the proceedings; up to two additional pages may be purchased at a price of $275 per page. In order to make blind reviewing possible, authors must omit their names and affiliations from the paper. Also, while the references should include all published literature relevant to the paper, including previous works of the authors, it should not include unpublished works. When referring to one's own work, use the third person rather than the first person. For example, say "Previously, Foo and Bar [7] have shown that...", rather than "In our previous work [7] we have shown that..." For accepted papers, such identifying information can be added to the final camera-ready version for publication.

Review Process

Papers will be subject to blind peer review. Selection criteria include accuracy and originality of ideas, clarity and significance of results and quality of the presentation. Each paper will be assigned to three Program Committee members, one Senior Program Committee member and one Area Chair for review. The reviewing process will include a short period for the authors to view reviews and respond to technical questions on the submitted work raised by the reviewers before final decisions are made. The decision of the Program Committee will be final and cannot be appealed.

Papers accepted for the conference will be scheduled for oral or poster presentation and will be printed in the proceedings. At least one author of each accepted paper will be required to attend the conference to present the work.

Please send inquiries about paper submissions to ijcai09@aaai.org.

2008-12-01T13:40:00.002+01:00

The ICML, UAI, and COLT conferences will be colocated in Montreal June 14-21 2009. We solict proposals for workshops to be held during a single joint workshop day on June 18. This date lies between ICML (June 14-17) and UAI/COLT (June 19-21). Workshops will be selected on the basis of their interest to the attendees of one or more of the conferences.

The goal of the workshops is to provide an informal forum for researchers to discuss important research questions and challenges. Controversial issues, open problems, and comparisons of competing approaches are encouraged. Representation of alternative viewpoints and panel-style discussions are also encouraged.

Organization

The format, style, and content of accepted workshops is under the control of the workshop organizers and largely autonomous from the main conferences. The workshops will be seven hours long and split into morning and afternoon sessions. Workshop organizers will be expected to manage the workshop content, specify the workshop format, be present to moderate the discussion and panels, invite experts in the domain, and maintain a website for the workshop. Workshop registration will be handled centrally by the main conferences with a single uniform registration fee and with registrants allowed to attend workshops other than the one they register for.

Submission Instructions

Proposals should specify clearly all of the following:

the workshop's title (what is it called?)
topic (what is it about?)
motivation (why a workshop on this topic?)
impact and expected outcomes (what will having the workshop do?)
potential invited speakers (who might come?)
a list of related publications (where can we learn more?)
main workshop organizer (who is making it happen?)
other organizers (who else is making it happen?)
workshop URL (where will interested parties get more information?)
relevant conferences (which of ICML, UAI, and COLT would it appeal to?)

Please also provide brief CVs of all organizers. This information should be sent by email (in plain text or pdf format) to Icml-uai-colt-workshops09@ssli.ee.washington.edu by 19 Jan 2009.

Review Process (New for 2009!)

Our review process this year will be slightly different from previous years to further encourage innovative papers on a variety of topics. Authors will indicate a preference for an area chair to handle their papers via an inverse bidding process. It is crucial for authors to familiarize themselves with the 2009 area chairs and their topic descriptiors (http://www.cs.rutgers.edu/~mlittman/icml09/ac.html). The goal is to ensure each submission is considered by reviewers appropriate to the paper's intended contribution. Each submitted paper will receive two first round reviews. As in recent years, authors will have the opportunity to see and respond to the reviews before a final decision is made. Papers that receive at least one positive review in the first round will receive one or more additional reviews. Final decisions will be made using the input from all reviewers, the author feedback, the assigned area chair, and programme co-chairs. Reviewing for ICML 2009 will be blind to the identities of the authors. No conditional accepts will be granted this year.

ICML 2009 will not accept any paper that is substantially similar to another paper that is currently under review or has already been accepted for publication in a journal or another conference. The programme co-chairs will consider making an exception for papers published in substantially disjoint communities (application conferences, for example), as long as the submitted papers are themselves clearly targeted to a machine-learning audience. Please clearly indicate which contributions are novel and which are previous work, either by the authors or others. If a paper submitted to ICML 2009 and another already published or already submitted paper contain substantial overlap in content and the content is not clearly indicated (anonymously) as being previous work, then the ICML submission may be rejected on the grounds of being a dual submission.

Similarly, authors must withdraw their papers if they submit an overlapping paper elsewhere during ICML's review period.

With your help, we expect another excellent conference!
