Why am I here? Where do I need to go? And how do I get there?

taa — Wed, 25 Aug 2010 02:31:31 +0000

Thinking about the meaning of life, God, religion, right and wrong, the universe, and everything, many questions to come to mind. But at a personal, fundamental level, it all boils down to three questions:

Why am I here?
Where do I need to go?
And how do I get there?

Most people focus on the first question: “why am I here?” They want their lives to have a purpose, or they believe they lives do have a purpose and they sincerely wish to find out what it is. Some have already come to terms with the first question, and at a very general level, they believe we are here to do something, or to achieve some objective – be it enlightenment, helping humanity, glorifying a supreme being, or just enjoying it while it lasts. For those, the focus is then on the second question: “where do I need to go?” In other words, while they have some believes or understanding about the general reason of why they are here, they want to know more specifically what it is that they need to achieve. Enlightenment – at what level? Helping humanity – to what extent? Glorifying a supreme being – to what degree? Enjoying it while it lasts – how much?

But I personally believe that if there was just one question the mattered, one question to which the answer would lead to all the other answers, the question would be the third one: “how do I get there?” In the process of getting there, I hope to understand why I am here. And once I get there, I hope to see where it is I was going. It’s the journey that makes up the difficult part, and is the secret to answering all the questions that we may have.

How to count search results in Gmail

taa — Fri, 21 May 2010 00:40:16 +0000

Gmail is a great products with powerful search and labelling systems that changed the way I use email. There is a small annoyance though – when doing search, Gmail does not return the total number of results if you have more than a few. Further, there is no easy way to access older results or see more than 20 results per page. Basically, you’d have to keep hitting the “older” button until you get to that last message. But what if you had hundreds or thousands of results from a mailing list, like I do?

Here is a power tip for Gmail users with thousands of messages on how to find the exact number of search results, browse 100 results at a time, and easily access the oldest messages:

Do a search, either regular or advanced through the “Show search options” link.
Select all the results by hitting “Select: All”
Really select ALL the results by clicking on the “Select all conversations that match this search” link
Apply a new label to the results, such as “Results Count”
A popup dialog will ask you “This action will affect all conversations in this search. Are you sure you want to continue?” Hit OK.
Now you can go to the “Results Count” label on the left side bar and:
1. See the total number of messages
2. See the total number of unread messages
3. Paginate through the messages up to 100 messages at a time
4. Access the oldest message easily through the now available “Oldest »” link.
If you no longer need this label, you can select all the message and clear the label so it’s usable in future searches.

Did you find this tip useful? I’d appreciate some feedback in the comments. Feel free to link to other Gmail power tips.

The Future of the Web: Mobile Apps to replace Web Apps

taa — Sun, 09 May 2010 05:53:42 +0000

After a recent report by Mobile Crunch that the mobile location-based game Booyah has outgrown Foursquares and Gowalla reaching 1 million mobile users, combined with recent reports on the future of the Web at top conferences on the subject, and affirmed by recent trends in VC’s investing strategies in the IT sector, I have become convinced that the future of the Web is in mobile apps and not Web-based applications, sometimes referred to as “software as a service”.

In the last decade, we have witnessed a revolution in Web app design both in terms of the user experience and the richness of functionality. Arguable, the most successful and revolutionary Web app for consumers has been Gmail, and more recently Google Apps. Facebook is another great example of a Web app, with more social focus. All is good, and more Web apps are coming, but then what?

While the laptop is becoming a replacement to the desktop for many, smart phones such as iPhone and Blackberry are becoming a replacement for laptops. The new trend in mobile consumer usage, set by Apple’s iPhone and followed by RIM’s Blackberry and Google’s Android, is to access services and information through apps instead of mobile-friendly websites. Is your website optimized for mobile access? Big deal – new mobile browser can render most websites in a usable fashion. But who cares? If you don’t have an app to access your site then it’s simply boring. I believe boring is not the main reason though. It all boils down to the look and feel. Mobile apps provide a consistent look and feel with the rest of the mobile interface, a lot more so that a Web page does.

Based on these trends, I believe that the value of “software as a service” as being the future of desktop apps for consumers will slowly (or quickly?) diminish; while mobile apps will increase in sophistication and become the norm for accessing your email, social networks, documents, spreadsheets, organizer, etc.

Some may argue that the desktop, or the laptop, will still be ahead in software due to the limited screen size that mobile devices affords. Apple has negated that claim last month with the release of its iPad. QED.

Reflection on PhD Defences in Canada

taa — Sun, 25 Apr 2010 04:22:20 +0000

PhD defences have become a bureaucratic formality to torment the candidate and entertain the professors.

The PhD Defence is the most important day of the entire program, not.

Having been through the process myself, as well as attending about a dozen of other PhD defences, I find that it is considered by the PhD students as one of the most important days in their lives, as if the success or failure of the past four, five, or most likely six years of work depends on how well they do on this special day. Little did they know – their fate had been decided about a week prior to the defence and there isn’t much that could go wrong during the defence, no matter how hard they tried.

Why doctoral defences are irrelevant

About 4-5 weeks before the PhD defence, your supervisory committee must sign a paper that states that they’re OK with proceeding to the defence. At which point, your thesis is distributed to the external examiner. About 1 week prior to the defence, the external examiner must submit a written report indicating whether or not the examiner is prepared to accept the thesis as satisfactory, typically subject to minor changes. Only upon receiving this, what I call “acceptance letter” from the external examiner that the defence data is publicized. So by this point, your supervisor, your readers, and your external examiner have all signed paper stating that they’re satisfied with the thesis. What’s left? Tormenting the student and entertaining the committee members. Once you make it to the defence, there are practically only two reason that may stop the committee from giving a final pass:

They discover that your data, experimental results, or references are fabricated; or
They discover that you have plagiarized a portion of your dissertation.

So unless you are guilty of one of the above 2 item, there is really nothing to worry about. I knew all this before my defence, and I was still as in intense the day before the defence as I ever was.

The Ceremonial Presentation

The PhD defence, thus, is a ceremonial events. It is a day to mark and celebrate the completion of a long journey, the end of a student life, the unofficial bestowal of the title “Dr.”, and a day of relief and joy for family and friends. From my personal experience as well as that of several people I personally know, the PhD student — now unofficially a Dr. — actually shares very little of this joy on this day. Overwhelmed by frustration, exhaustion, and confusion, their happiness is only a reflection of the happiness of their close ones. Which is why it is important for family and friends to recognize the significance of their support on this day, preferably by attending the defence. Without this support, without the caring audience, the show brings little joy to the performer.

Clarification: the goal of this article is to educate, entertain, and relieve some of the stress that future PhD defenders are going to face. It is not my intention to downplay the importance of the defence in the educational process, except in a humours and sarcastic way.

How twitter and facebook almost killed my blog

Preface

It’s been about 6 months since I last wrote on this site. And instead of writing about something useful, here I am writing about writing and not writing .. the boring useless stuff that few would care about. But wait, isn’t that the reason why I didn’t write for so long in the first place? Wasn’t it because I didn’t want to write about boring useless stuff that few would care about? C’est la vie. Life must go on, and for a site to maintain its livelihood, it’s got to be updated once in a while.

Twitter (Almost) Killed My Blog

But another more realistic reason for not writing this long is the new social media. I’ve been writing on twitter and facebook many times a day. Most of what I wanted to say I could squeeze in 140 characters, including a link, a couple hash tags, exclamation marks, and space to spare for retweets. Now that’s efficiency! But if I can be that efficient on Twitter and Facebook, and I feel I have something worthy to say there, then why not here, on my very own personal blog? Aren’t these condensed, super-efficient revelations worthy of “the Web”? Is there a minimum length requirement for blog analogous to the maximum length requirement of a tweet? Is blogging, then, the opposite of tweeting?

Conclusion

Long story short, this story is already too long. What I wanted to say was “I’m back to blog again.” Period.

Atlantic Canada’s War-of-Minds at Dalhousie University, Halifax

taa — Sun, 25 Oct 2009 01:21:41 +0000

Friday, October 23, witnessed the most anticipated programming competition in Atlantic Canada. Teams from Atlantic Canadian universities gathered at Dalhousie University in a show-off of programming and problem-solving skills. Each team consisted of 3 participants, mostly undergraduate computer science students. The teams were given 5 hours to tackle 6 problems. The problem complexity ranged from easy, suitable for second year undergraduate students in computer science, to more complex ones that even graduates would find challenging. The algorithmic solutions to the problems ranged from basic searching and sorting, to dynamic programming, to geometry.

17 minutes into the contest, the SMU Huskies, led by my colleague Chris Adams, solved their first problem. Withing the hour, a few more teams solved their first problem, but by that time SMU Huskies had already solved their second problem. They were on the roll.

At the end of the competition, the Huskies had solved 4 out of 6 problems, qualifying to compete at the ACM ICPC Northeast North America Programming Contest in Fredericton, NB, next Saturday.

The final results were announced at the APICS conference today:

#4 smu_huskies 4 problems 456 minutes
Saint Mary’s University, CS Huskies
Chris Adams, Jonathan Kenney, Lucas Mannell
#14 mounta_thought, 2 problems, 126 minutes

Congratulations to Chris and SMU for a well-deserved victory, and better luck for the other teams next year.

Memories of Milan, Italy: Historic Churches

taa — Tue, 13 Oct 2009 04:21:00 +0000

The churches in Milano are just fascinating. I spent many hours during my trip in Milan going from one historic church to another. And although this started because there wasn’t much else to do, I kept going because I enjoyed it so much. I visited a total of 5 churches, each with a unique style, history, Christian artifacts, and wall paintings.

The first was Duomo, Milan’s most known treasure. Duomo is a huge church fully covered in engraved marble. All these statues and figures and patterns were all so detailed, so perfect, and so breathtaking. in the centre of the church, high above it, stands a golden statue of Virgin Mary.
Basilica of Sant’Ambrogio had the oldest of the Christian artifacts, dating back to early Christianity and was built by St. Ambrose in the 4th century. Here I discovered that Victor is actually the name of a saint.
The most memorable elements of Santa Maria presso San Satiro were the hundreds of paintings of saints and angles painted on the ceiling of the church. The church, as many others, is kept dark. Therefore, to the painting are hard to see by the naked eye (having them on the ceiling doesn’t help either) but can be viewed with the help of a camera that is able to capture more light that the human eye.
Santa Maria delle Grazie is a UNESCO World Heritage Site. It is the church were Leonardo da Vinci painted the Last Supper, although the building housing the painting is no longer considered part of the church.
Basilica of San Simpliciano captured my senses with all the art it houses, from paintings by famous and less famous artists, to stained-glass windows. The art comes from a wide range of periods, the earliest dating back to the 4th century.

New Book: Quantifying Uncertainty in Reasoning and Question Answering

taa — Sun, 04 Oct 2009 02:12:57 +0000

Probabilistic Relaxed Unification Formalism and Applications in Automated Question-Answering Systems

Reasoning about natural language requires robustness in the face of uncertainty about the validity of the information contained in the text. Many natural language processing formalism rely on classical unification, which assumes that the knowledge base is complete and accurate. However, this seldom applies to the real world; text from the Web may contain incorrect, incomplete, or contradictory information. We introduce probabilistic relaxed unification as an alternative approach where the assumptions of classical unification are relaxed. Relaxed unification replaces the binary success or failure outcome of classical unification with a real number quantifying the correctness of the result. Our formalism is realized in the implementation of a modular question-answering system prototype. Our approach is empirically validated through a series of cases drawn from real world questions and data collection. The validation cases substantiate that our system provides satisfactory results on the chosen dataset within the system limitations. This book should be of interest to academics and practitioners interested in reasoning under uncertainty and automated question-answering systems.

I was recently invited by VDM Verlag to publish my PhD dissertation as monograph. The way it works is that the author does all the work for preparing the manuscript, there is no editorial proof-reading or any type of content or formatting assistance. On the other hand, the publisher handles all the distribution and printing at no cost to the author. It’s a good deal if you’re looking for a low-risk (no cost to you) low-return publishing opportunity. The author receives some royalties, but they’re generally insignificant.

One significant difference between the book and the dissertation is the addition of an index. Learning about writing an index was both pleasant and frustrating, and it is my hope that the effort it took will prove of use to the reader.

The book is 156 page and available from Amazon at $84.00 USD. ISBN: 978-3639171402

If you’re interested in publishing your manuscript through VDM Verlag, let me know and I will make the introduction. Disclaimer: I get a free book for every referral that leads to a publication.

Memories of Milan, Italy: Transportation

taa — Sat, 26 Sep 2009 03:12:35 +0000

Milan has an extensive public transportation system that consists of trains, metro, trams, and buses. The train connects the Malpensa airport to Milan. The ride takes about 40 minutes and costs 11 euro. The city of Milan and the suburbs are covered with a star-shaped metro system. The metro run regularly, and there is insignificant wait time between trains during the day. City travel is only 1 euro, but if you’re coming from suburbs then it’s 1.5 euro.

Covering the suburbs is a network of over 60 bus and metro lines, augmented with about 100 lines for urban area. Needless to say, such a large network can’t be printed meaningfully on a map. So while the metro map is posted all over the city and on all maps of Milan, the bus map is only accessible from the ATM website. Unfortunate for me, the ATM website was recently redesigned and the English version is “coming soon.” If you speak Italian, however, the site is quiet amazing with search functionality and public-transit routing directions. The map is interactive allowing you to view the bus/train arrival times for each stop. Keep in mind that Milan transport is imprecise, and it was common for the bus to arrive 5 minutes early.

One inconvenience for visitors is that bus ticket must be bought it advance and validated on site. So if you’re at a hotel in the middle of nowhere with no stores selling bus tickets nearby, you’re out of luck. Or are you? You can still ride, as long you don’t get an inspector on your ride.

As for private transportation, namely taxi, two things to keep in mind: except for high volume tourist areas, you pretty much have to call for a cab; and they take cash only. And it doesn’t matter that you call for a cab with credit card capabilities, they still take cash only and have a thousand excuses why they couldn’t process your credit card. I speak from a sample of 3!

The Twitter Times – Personalized News from Your Tweeps

taa — Mon, 07 Sep 2009 16:32:12 +0000

The Twitter Times is an interesting news site that is built on top of the Twitter real-time stream. The site describes itself as:

“The Twitter Times is a real-time personalized newspaper generated from your Twitter account.”

It basically monitors the global real-time Twitter stream, identifies news stories that are tweeted and re-tweeted, cross-references them with you friends and their friends, and brings them all in one, well-organized place. The best part of it all, you get the all the news stories on one page – no visiting multiple sites, no following links to see what the tweet is about.

The Twitter Times is a time saver for me. I follow almost 200 streams on twitter. There is no way I can read them all. Some of these streams are of my friends, and I’d like to read them all; others I follow for the news they post, which I can now read on the twittertim.es.

I had the pleasure of meeting one the creators (@mariagrineva) and speaking with another (@maxgrinev). Congrats Maria and Maxim!

Third Wednesday Social Media Tweetup – Impressions

taa — Thu, 20 Aug 2009 02:37:06 +0000

Third Wednesday (#thirdwednesday on twitter) is a monthly informal networking event. There is no RSVP or membership, just show up at Foggy Goggle on Argyle Street between 5-7 PM on the third Wednesday of the month.

Today’s topic was Twitter and how local Halifax businesses use twitter to interact with customers and clients. It was facilitated by Michelle Yogis (@myogis). Highlights of comments made:

Many local businesses in Halifax are active on twitter
No measurable ROI at the moment
There must be a single person behind a corporate twitter account – the interaction needs to be personal
Main value comes through building relationships and branding, no immediate increase in sales
Twitter should be considered in an integrated marketing plan and not on its own

Over 35 people attended the August meeting. A few prizes were given away in a mini-contest, where answer to questions were submitted through twitter (although the questions themselves were not).

All in all I think it is a great, relaxing event to meet locals from all industries who are passionate about the Internet, the Web, and the new social communication tools online.

Personalization of Content Ranking in the Context of Local Search

taa — Fri, 03 Jul 2009 20:21:51 +0000

My paper entitled “Personalization of Content Ranking in the Context of Local Search” has been accepted for publication at the IEEE/WIC/ACM International Conference on Web Intelligence (WI2009) as a regular paper. The acceptance rate was pretty low at 16%. The conference will be co-located with the Intelligent Agent Technology Conference (IAT2009) in Milan, Italy. My colleague and co-author Philip O’Brien and I will be presenting the paper. The other co-authors are Xiao Luo, Weizheng Gao, and Shujie Li. The conference will be held in September 15-18, 2009 at Università degli Studi di Milano Bicocca.

If you’re planning to attend WI/AIT 2009 and would like to connect, contact me.

The abstract of the paper follows:

Ranking search results using a single ranking function for all search engine visitors is inherently bounded in the performance the ranking algorithm can achieve when considering the variety of requirements of Web searchers and the proliferation of topics and types of data modern search engines rank. Adding a geographical dimension to the mix by way of local search engines further reduces the average satisfaction a ranking algorithm can garner from local search users. Personalization has been proposed in Web search with some success but has not, to our knowledge, been investigated thoroughly in local search. As initial steps in local search personalization, we propose a model for personalizing search results in a local search engine using a hybrid of profile- and click-based user modeling methods. User profiles are used to compare local search results to the topical interests of users and the specific businesses in which they have shown interest by way of search result “clicks”. Our model is tested through a user study and is shown to result in significantly improved mean average precision over the baseline ranking system.

Although experiments were conducted in the context of Local Search, the framework for modelling user interests is transferable to any domain where semantic similarity between users or user and objects is of interest. If you have any questions or comments about our approach, I’d be happy to discuss it in person or electronically – just give me a shout!

I would like to thank the staff at GenieKnows.com for their assistance and feedback both during the experiments and during writing the paper. Special shouts go to Stephanie Armsworthy, Jason Hines, and Jacek Wolkowicz, and Tapajyoti Das. Additional acknowledgements will appear in the paper.

Advice from Successful Ladies and Men

taa — Thu, 02 Jul 2009 13:54:46 +0000

CNN Money has an excellent articles where they interview 22 people from political leaders, company executives, investors, entrepreneurs, and even a chef, asking them to share the best advice they ever got. Below is a summary of their answers:

“Keep it Simple” – Tiger Woods
“Show, don’t tell” – Jim Sinegal
“Do what you love” – Mort Zuckerman
“Empower a subordinate” – Lloyd Blankfein
“Push beyond your comfort zone” – Mohamed El-Erian
“Ignore conventional wisdom” – David Axelrod
“Trust your instincts” – Tory Burch
“Read everything” – Jim Rogers
“Be effective, not popular” – Scott Boras
“Use failure to motivate yourself” – Mika Brzezinski
“Focus on performance, not power” – Colin Powell
“Take advice from smart people” – Shai Agassi
“Make an impression” – Sukhinder Singh Cassidy
“Hire a coach” – Eric Schmidt
“Set realistic goals” – Meredith Whitney
“Listen” – Lauren Zalaznick
“Don’t talk shop” – Julian Robertson
“Treat it like it’s yours” – Thomas Keller
“Underpromise and overdeliver” – Robin Li
“Don’t pursue titles and dollars” – Miles White
“Self-doubt is normal” – Aaron Patzer
“Be nice to people” – Niklas Savander

My favourite three from the list are “take advice from smart people”, “Keep it Simple”, and “Show, don’t tell.” Each of these three advices I have come to experience as being true wisdom and highly effective in a diversity of situations.

Halifax Tattoo Festival Shrinking Every Year

taa — Thu, 25 Jun 2009 02:01:00 +0000

The Royal Nova Scotia Tattoo Festival is a yearly tradition in Halifax, NS featuring performers and miltary bands from around the world. The first time attended the festival was back in 2005 and I absolutely loved it. It was such a well organized show, so many performer, amazing bands, dancer, acrobats, and clowns. And the best part of it all was the finale were all the bands would play in unison creating a grand orchestra.

I loved the NS Tattoo so much that I went back the following year in 2006. It was not as big or as good as the 2006 show, but it was still enjoyable. In all honesty, there was a little bit of disappointment that it was getting smaller, yet the performance of 2006 made up for big part of that. The 2006 year was special for NS tattoo, it was the year it was given the Royal status by Her Majesty the Queen for her 80th birthday.

In 2007, the cast was shrinking even more. I thought I’d give it the benefit of doubt and attended anyway. Maybe if it was my first time attending I would’ve liked it, but seeing how it didn’t live up to the 2006 show, leave alone the 2005 performance, I must say I was greatly disappointed. I felt cheated in many ways because the prices didn’t go down, but the quality did. I had hopes that achieving the Royal designation would help the festival grow, but it was not to be.

I had to skip 2008 for personal reasons – by son was under a year old, I was 2 month away from defending by PhD dissertation – not a good time for big fun events.

This year, in 2009, “performer from around the world” really refers to only nine countries: Canada, Belgium, Denmark, Estonia, France, Germany, Sweden, United Kingdom, and United States. There are a total of 30 groups confirmed, but 20 of them are from Canada. This is very different from previous years were we had more international participation. I am especially disappointed that the Russian and Ukrainian dancers are not in this year’s show.

My plan for this year is to go see the parade and then decide whether to attend the big show or not.

One piece of advice: if you’re planning to attend, go for the cheap tickets. I’ve tried different seating and they were all equally great. There is typically plenty of empty seats, so moving around is possible if your seat turns out to be not so great.

Future of the Web: Mobile + Social + Linked

taa — Thu, 07 May 2009 12:59:31 +0000

By now, it should be clear to everyone that the future of the Web is mobile devices, social networking, and linked data. Although this realization did not come to me until I attended the World Wide Web Conference (WWW2009) in Madrid, Spain, at the end of April. Several keynote speakers, tutorials/workshops, and dedicated tracks and sessions emphasized this fact. I’ll say a few word on each of the three pillars:

Mobile Web

As Sir Tim Burners-Lee said in his keynote presentation: “more people will have their first encounter with the Web through a mobile device than a laptop.” The World Wide Web Consortium (W3C) has task forces and standards to promote and standardize the mobile Web. They’ve been doing it for years, but only now that people are listening seriously because it is already happening.

What this means to the Web community is that Web sites should have a mobile version that conforms to standards and guidelines and works well on mobile devices.

Social Networking

It is a given that social networks are taking over the Web. But that’s not what “the future of the Web is social networking” means. Social networking on the Web refers to enabling the end users to interact with each other on your Web site. Without this interaction, your site will fail to deliver the expected value by the growing savvy Web population.

Linked Data

The Semantic Web is dubbed as Web 3.0. Many believe that a widespread of the Semantic Web is at least a decade away. Linked Data, on the hand, is already a reality. Linked data consists of the now-feasible subset of the Semantic Web. At the very basic level, it is RDF + URI: a common data representation format and standard for addressing and linking data items. The academic community emphasizes the important of Linked Open Data – making your proprietary databases accessible on the Web in the Linked Data format. This movement is new but strong. Many tools are being developed to facilitate the transition to Linked Data for the masses.

Summary

In short, as a Web site owner, if you want to survive on the Web for the years to come, you better ensure that your site is accessible from mobile devices, that you facilitate social interaction among your users, and that your data is open and linked, and linkable.

Thanks to Christopher Gutteridge for this wonderful tool to search and browse the WWW2009 proceedings.

Two Papers Accepted at the WWW 2009 Developer Track

taa — Sat, 11 Apr 2009 05:06:41 +0000

The World Wide Web Conference (WWW2009) will be held in Madrid, Spain, April 20-24, 2009. I will be co-presenting two papers at the Developer track. The first paper is co-authored with Jason Hines and entitled “Query GeoParser: A Spatial-Keyword Query Parser Using Regular Expressions”. The second paper is co-authored with Christopher Adams and entitled “Creating Your Own Web-Deployed Street Map Using Open Source Software and Free Data”. Both papers will be presented in the afternoon of Friday, April 20. The schedule, as well as a link to the proceedings, can be found on the Developer’s Track page. The paper abstracts follow.

Query GeoParser: A Spatial-Keyword Query Parser Using Regular Expressions

Abstract: There has been a growing commercial interest in local information within Geographic Information Retrieval, or GIR, systems. Local search engines enable the user to search for entities that contain both textual and spatial information, such as Web pages containing addresses or a business directory. Thus, queries to these systems may contain both spatial and textual components—spatial-keyword queries. Parsing the queries requires breaking the query into textual keywords, and identifying components of the geo-spatial description. For example, the query ‘Hotels near 1567 Argyle St, Halifax, NS’ could be parsed as having the keyword ‘Hotels’, the preposition ‘near’, the street number ‘1567’, the street name ‘Argyle’, the street suffix ‘St’, the city ‘Halifax’, and the province ‘NS’. Developing an accurate query parser is essential to providing relevant search results. Such a query parser can also be utilized in extracting geographic information from Web pages.

One approach to developing such a parser is to use regular expressions. Our Query GeoParser is a simple, but powerful, regular expression-based spatial-keyword query parser. Query GeoParser is implemented in Perl and utilizes many of Perl’s capabilities in optimizing regular expressions. By starting with regular expression building blocks for common entities such as number and streets, and combining them into larger regular expressions, we are able handle over 400 different cases while keeping the code manageable and easy to maintain. We employ the mark-and-match technique to improve the parsing efficiency. First we mark numbers, city names, and states. Following, we use matching to extract keywords and geographic entities. The advantages of our approach include manageability, performance, and easy exception handling. Drawbacks include a lack of geographic hierarchy and the inherent difficulty in dealing with misspellings. We comment on our overall experience using such a parser in a production environment, what we have learnt, and suggest possible ways to deal with the drawbacks.

Creating Your Own Web-Deployed Street Map Using Open Source Software and Free Data

Abstract: Street maps are a key element to Local Search; they make the connection between the search results, and the geography. Adding a map to your website can be easily done, using an API from a popular local search provider. However, the lists of restrictions are lengthy and customization can be costly, or impossible. It is possible to create a fully customizable web-deployed street map without sponsoring the corporate leviathans, at only the cost of your time and your server. Being able to freely style and customize your map is essential; it will distinguish your website from websites with shrink wrapped maps that everyone has seen. Using open source software adds to the level of customizability – you will not have to wait two years for the next release and then maybe get the anticipated new feature or the bug fix; you can make the change yourself. Using free data rids you of contracts, costly transactions, and hefty startup fees. As an example, we walk through creating a street map for the United States of America.

A Web-deployed street map consists of a server and a client. The server stores the map data including any custom refinements. The client requests a portion of the map and the server renders that portion and returns it to the client, which in turn displays it to the user. The map data used in this example is the Tiger/LINE data. Tiger/LINE data covers the whole of the USA. Another source of free road network data is OpenStreetMap, which is not as complete as Tiger/LINE but includes additional data such as points of interest and streets for other countries. Sometimes the original data is not formatted in a manner that attributes to a good looking, concise map. In such cases, data refinement is desired. For instance, performance and aesthetics of a map can be improved by transforming the street center lines to street polygons. For this task, we use the Python language, which has many extensions that make map data refinement easy. The rendering application employed is MapServer. MapServer allows you to specify a configuration file for your map, which consists of layers referencing geographical information, as well as the style attributes to specify how the layers are visualized. MapServer contains utilities to speed up the rendering process, and organize similar data. On the front end, we need a web-page embeddable client that can process requests for map movements, and scale changes in real time. In our experience, OpenLayers is this best tool for this task; it supports many existing protocols for requesting map tiles and is fast, customizable, and user friendly. Thus, deploying a street map service on the Web is feasible for individuals and not limited to big corporations.
