World Wide Lexicon Toolbar changes the reading experience for the other 99% of web pages

Brian McConnell's latest coding effort, World Wide Lexicon Toolbar, meets my criterion for a piece of critical infrastructure: after two days with it I can't get along without it, and I plan to avoid any browser that doesn't have it installed.

Brian is a highly adaptive programmer. With roots in the telecom industry and several start-ups on his resume, he also wrote Beyond Contact: A Guide to SETI and Communicating with Alien Civilizations for O'Reilly. The World Wide Lexicon project he's been working on for the past several years is again something totally different.

Install the add-on (currently experimental) in Firefox 3.5 or higher and visit a page in some language other than your default. Before your eyes, headings and text change into your native language. You can get similar effects by submitting the page to a popular translator such as Google (which is one of the tools used behind the scenes by the WWL toolbar), but the instantaneous effect of the toolbar makes you feel closer to the people whose sites you visit around the world.

There are several languages that I know well enough to get the gist of a page, but where I miss some of the details and get frustrated by gaps in my vocabulary. Therefore, I set the WWL toolbar to "Bilingual view," so each block element of the original text is shown together with its translation. The bilingual view is considerably less attractive, because it swells the size of each block element, but I can tell already that it will improve my language skills quickly.

WWL is designed for volunteer translations. If it becomes more popular, people will submit translations that are much more accurate than the machine-generated ones the WWL must fall back on currently.

What's the process behind this new dimension to web browsing? McConnell let me in on some of the magic.

Volunteer translations

McConnell invented WWL several years ago with the core notion of encouraging people to translate web pages they thought should get a wider audience. When he first told me about the idea, I was skeptical that he would get many volunteers. But then I heard of other volunteer translation efforts. For instance, there's a whole subculture of people who write subtitles for popular Hollywood films. This runs afoul of copyright law, of course (and so do the copies of movies they're attached to, probably) but they show the lengths to which crowdsourcing has progressed in the translation area.

FLOSS Manuals, a project I do volunteer work for, also finds dozens of people willing to translate its open source documentation.

McConnell's first set of tools were designed to facilitate on-the-fly translations. Web designers could enhance their web sites by downloading from the WWL site some JavaScript that made each text element on the page editable. (I blogged about this in December 2007.) The paste-in displayed a little pencil icon, signaling to viewers that they could do instant translations. All they would have to do was click on an element, and a text box would pop up where they could enter their translation. The web site would then register the translation with the central WWL site.

World Wide Lexicon API

The WWL API covers the entire life cycle of a translation: registering a translation, rating translations for quality, searching for a translation of a particular page into a particular language, and retrieving a translation. Queries can specify a minimum rating.

Toolbar

The latest achievement of the WWL project is the toolbar officially released yesterday. It determines the user's native language through settings in the browser. When each page is visited, the toolbar uses the domain name and various tests on the text to make a guess about its language.

The toolbar then issues an API query to see whether any human translations exist. If so, it displays the translations with a light yellow or green background.

If no one has made a human translation (which is usually the case so far) the toolbar resorts to well-known machine translation services. It can make use of Google Translate, Apertium, and Moses, each of which offers an API, and will also query Babelfish when its API is ready. Machine translations are displayed with a light blue or grey background.

The progressive translation used by the toolbar is also interesting. It starts with the first 10 or 20 elements, then translates heading tags (<H1>, etc.), then the larger texts, and ultimately every element on a page. (I displayed one page that embedded a Google ad, and the translator recognized and translated that text too.) McConnell is working on making the various translations run in parallel. Because translation changes the sizes of elements, the toolbar makes various accommodations to display the page as attractively as it can.

In short, WWL is a cool combination of mash-ups, existing services, crowdsourcing, and Ajax. I'm sure that in a year's time I'll think back to its appearance today and be shocked at how primitive it was. But it will remain a transformative tool for me.
