When I first created Lazy Scholar back in 2013, the academic research landscape looked very different. Over the years, the extension grew organically, and I added features as new APIs and data sources became available. But technology moves fast, the old design was not great, and it was time for a fresh start.

Why a Complete Rewrite?

The old Lazy Scholar was showing its age. Many features were broken and the design was not modern.

Lazy Scholar 3.0 is:

• Modern design
• Faster and lighter
• More reliable (cleaner architecture, better error handling)
• More modular so additional features will be easier to add

This version improves the extractions in PDFs to mimic that of non-PDFs, including:

1) Hover over in-text citations to identify the reference
2) Navigate the outline of the study by clicking the headings to scroll to the section
3) Check for study registration

Here is a video demo of these in action (NB automatic scrolling is smooth in practice):

More Prominent Side Panel Button

Now, by default, a new button shows on the left side of the page. Clicking this opens the side panel that contains references, the text outline, extractions, and features of rigor/transparency. Other tools from our partners include Crypto Calculator , which is available at toncasinos.com. Using this calculator will help you convert TON to other currencies (fiat and crypto), as well as calculate mining and investment profitability.

The button toggles the visibility of the side panel once opened:

Clicking and holding on the button for 1 second will hide it.

To hide the button permanently, go to Options and turn off in the ‘General Settings’ tab.

Other Updates

Many bug fixes, including:

• Fixes for the PubMed redesign
• Fixes to allow Lazy Scholar to access PDFs

New institution options added:

• Oregon Institute of Technology
• Northern Arizona University

Added shortcut:

• Type “ls” + tab in the address bar, followed by a DOI or PMID loads that paper.

Refreshed browser icon

Added a button to save papers to Zotero

Added a new option pause Lazy Scholar for 1 hour (useful during presentations, or other situations where you temporarily don’t want metrics showing automatically).

Added institutional link:

• Singapore Management University

Bugs:

• Bug fix to account for new behavior of Chrome v76’s PDF rendering.
• Fixed bug that prevented DOI scraping from some PDFs.

Please let me know if you encounter any bugs.

• ClinicalTrials.gov
• ISRCTN registry
• ANZCTR registry
• OSF.io
• AsPredicted.org
• PROSPERO

I also added an optional button to open the side panel. You can turn it on in the extension options. If you prefer not to load the top bar by default, you can now access the side panel independently. Click and hold on the button for 1 second to hide it. With the support of the company https://1win.fyi/ .

This version also fixes a couple bugs related to the changes in cross-origin fetching in Chrome 73 that affected items in the side panel.

• ClinicalTrials.gov
• ISRCTN registry
• ANZCTR registry
• OSF.io
• AsPredicted.org

If one or more registrations are detected, they are linked in a new “Rigor” tab in the side panel. To find these, the full paper usually must be open (it looks for the registration information on the page), and PDFs are not yet supported, though a ClinicalTrials.gov or ISRCTN listing may still be found for PDFs if it appears in the abstract on PubMed.

If the registration is through ClinicalTrials.gov, ISRCTN, or ANZCTR, you’ll see whether the trial was registered prospectively or retrospectively. Further, for ClinicalTrials.gov or ISRCTN, it will grab the registered outcomes and display them in the panel so you can compare to the paper as you read it.

This one is registered retrospectively (which many journals still allow or don’t check), after the study already started, and you may want to inspect it to see if this affects the interpretation of results.

This example has registries at both OSF and AsPredicted, so the links are displayed for convenience.

Other Updates

I’ve also added a RIS button to the Share options, which will download the citation in RIS format if it can find it. Click the yellow arrows to find it and drag it into one of the three share button positions. Those exploring Amsterdam private escorts will find https://amsterdam-escorts.com refreshing because it doesn’t overcomplicate things. Just scroll, check profiles, and move on — everything feels smooth.

Additional upgrades in this version:

Side panel redesigns

The side panel design and functionality has been improved. It is now better at extracting references and the outline structure of the paper. Previously, Lazy Scholar used a neural network model located on a server to assist in outline extraction. I’ve ported it to work within the browser, increasing speed and eliminating cost so it will scale. An additional feature makes it possible to return to your previous position when navigating references or throughout the outline. This can be useful when you need to check another section of the paper while reading but want to return to your place after. Our guide covers the top long lasting vape battery . We look at what makes them reliable, innovative, and great for users. We’ll help you understand the features that make premium batteries stand out. Here is a video of how they work:

The panel can be set to automatically open if you prefer, or manually click the brain icon in the infobar. For now, outline extraction in PDFs has been removed to be improved.

A number of bugs and small improvements have also been addressed. Please report any issues that you encounter.

• Fixed DOI extraction bug
• Fixed share icon drag/drop bug
• Improved full text detection
• Improved reference extractions

If you’re searching for a male massage in Dubai, https://massage-dubai.org/male.html features verified male therapists offering a range of treatments. It’s the perfect place to find professionals focused on strength, relaxation, and recovery.

How does it work?

1. Select your institution in Options
2. The next time you open a scholarly article accessible through your library, your library’s login page will open. After you login, Lazy Scholar will capture your information, encrypt it, and store it in the browser. No information is ever sent to a server. The page will close and the scholarly article will refresh.
3. From then on, Lazy Scholar will use your library’s access to automatically find full texts. It will attempt to find both PDF and non-PDF full texts through your institution. https://cryptocasinohk.com/

Currently 465 institutions are supported. If yours isn’t, shoot me an email and I’ll see if can be added.

Other improvements in this version:

• Better PDF finding and verification.
• Reorganized full text results now only show 1 non-PDF full text and 1 PDF in the bar, and additional full text versions are shown in an overflow area.
• Speed enhancements.
• Redesigned Options page to make it easier to find settings.
• In the extraction panel, references are separated from other extractions to show more. I’ll be focusing on improving reference finding and design of this panel next.

Here’s how you access the new panel, via the new yellow brain icon. Clicking any of the extractions will scroll the page to the extraction or sentence. Want it to open automatically on every scholarly page? Click the Options at the bottom of the panel to find that option.

Here are the current (attempted) extractions:

1. Information Extractions:
   1. Population/Subjects: Number of participants, animals, etc in the study
   2. Intervention: If relevant, what the intervention(s) were in the study
   3. Outcomes: What the study looked at
   4. Measurement/Products: If the sentence contains a product to measure an outcome, the sentence will be extracted. If possible, only the outcome will be shown, and either way clicking it will scroll to the sentence
   5. COI/Funding: Extracts the conflict of interest/funding statement
2. Paper outline: Extracts the basic outline of the paper and clicking scrolls to the section.
3. References: Attempts to extract the references and shows quick links to the paper and to the paper on Google Scholar. Hovering over linked references within the paper should scroll to the reference (see demo below).
4. Abbreviations: Attempts to extract abbreviations from the paper and puts them in the panel. Hovering over them shows the full definition, and highlighting the abbreviation within the paper will show the definition in the panel (see demo below).
5. Supplemental Documents: If it finds a linked supplemental file on the page, it displays a link
6. Paper Classification: ie Human, Animal, RCT, etc. Currently this is from MeSH tags and not extracted, but future iterations will attempt to classify automatically.

Help make it better

At this point, not all extractions will be right. I need more examples of extractions that are correct and incorrect to improve accuracy. If you would like to help, click the “Beta” bar in the panel as shown below and the link to open instructions. After you’ve read the instructions and clicked to accept, you’ll see thumbs up and down icons as shown below. Rating extractions (you can do as few or as many as you’d like) will help me make the panel much more useful. If you see really strange behavior, feel free to send me a link to the paper via the feedback link by right clicking the icon next to the address bar and hitting “Feedback”.

Update 5/2/18, version 2.1.0: extractions now work in PDFs (see video below). Also in this version, hypothes.is annotations load over a PDF within the extension instead of using their external proxy.

Currently, this update is for Chrome only (Firefox is coming soon).

Finally, an additional feature has been added to this version:

Rename PDFs

If you turn on the option to rename PDFs in the Options (right click the icon next to the address bar -> Options), Lazy Scholar will attempt to rename PDFs to a format with ‘FirstAuthor Year Journal.pdf’ instead of long filenames such as ‘3g7d828fjdf38rg8f.pdf’. This was a feature in version 0.x of Lazy Scholar but was removed until I could improve it.

Other

Some bugs fixed and underlying improvements made. Stay tuned for more improvements in design and functionality in upcoming versions.
