Hi All,
Tomorrow we will hear about recent (actually ongoing) work of Antoine Bordes, jointly with Jason Weston and Ronan Collobert. Hope to see you all there.
When: November 11th 2010 @ 14h30 Where: LISA Lab (AA3256)
Title and Abstract:
How to embed any symbolic knowledge-base into a meaningful vector representation. ----------------- Since the 18th century and the first "Encyclopedie" of Diderot and D'Alembert, one has always wanted to group, organize, and classify knowledge. Recent developments of this trend concern the building of knowledge bases (KB) which are special kinds of relational database for knowledge management, collection, and retrieval. Examples of such KB involve Cyc, Freebase or WordNet. Even though these KB encompass colossal quantities of information, accessing or manipulating it can sometimes be complicated due to the limitations and rigidity of their underlying symbolic framework. In this talk, we present some preliminary work on how to embed these symbolic representations into a more flexible and complete continuous vector space in which the original knowledge is kept and enhanced. We illustrate this method on WordNet and sub-parts of Freebase.
Cheers, Aaron
