A delayed mention of Aaron Swartz

1/23/2013

0 Comments

 
Aaron Swartz was only 26 when his dead body was found in his New York apartment on Friday January 11th 2013.
The video below is a a face-to-face interview that nicely portraits what Aaron Swartz  stood about.
It's hard to add something new to the world tribute about Swartz.
Perhaps you remember that back in 2011 he was charged for his downloading about 4 million academic journal articles via JSTOR, a service that provides students and researchers access to a limited number of articles free of charge.
Or, his role in preventing SOPA. Because of his obvious leadership in activism for internet freedom, many think that his hanging was not exactly accidental. It would be a sad sad world indeed if the rumors were true.
RIP Aaron.

Facebook's new graph search 

1/16/2013

It was high time Facebook would improve on its searching capability.
Searching within Facebook and in your network of friends and friends of friends was an overdue feature.
So far, Facebook search has meant searching in the rather narrow field of people names within Facebook but outside a specific user's network of friends. Web search results (delivered by Bing) were also available often completely unrelated to the targeted Facebook search. Most FB users when searching within FB, clearly don't need to search on the web or they would simply switch  to google or some other general-purpose search engine.
With FB's new "graph search", the search will be specific to the search user's network of friends (as far as the information has been shared with this specific user or with the public) and it won't only be about people's names.  Indexed are also places, photos and any other clearly categorized information people put on their FB pages.
Still in beta for US users.
Update [March 15th]: Graph Search is rolling out very slowly. Will come back with examples when I have access to it. In the meantime, enjoy this as an intro to the tech behind it.

Norvig vs. Chomsky on the future of computational linguistics

1/16/2013

Well, yeah, most people think this is about "the future of AI" but the specific branch of AI that deals with natural language processing is called Computational Linguistics.
When Norvig and Chomsky's voices met at last year's MIT's Brains, Minds, and Machines symposium we had a chance to finally witness out in the open a debate that has been brewing for the last decade or so in the field.
Norvig, the head of research at Google, represents the modern CL, which emphasizes what Chomsky called "a method of doing linguistic analysis without involving language and the linguistic science" (my paraphrasis).  Machine learning and statistical analyses of language are two well-known manifestations of such method.
The debate was inevitable.
Google is notorious for (successfully) doing natural language processing without special regard for natural language.
And Chomsky is notorious for (successfully) doing linguistics without special regard for real-life data.
So, who's right and who's wrong? Can truth be found on one side of the table? Is there a possibility of finding the truth in between the two extremes? And if so, what exactly is the truth about the "right way" of processing natural language?

     A computational linguist's pond. Sometimes informational, some others instructional, or just a vent about the state of the field nowadays.
