Program

 Here's the program and the accepted papers (PDF)

The symposium will start on Wednesday 20, November 2013 at 9:15 AM and will end on Friday 22, November 2013 at 1 PM.

The symposium includes keynote talks, regular paper presentations, and a poster session.

We also offer space for and two panels (one on Textual Inference and one on Distributional Semantics) and two tutorials.

 Tutorials
 
  • Tutorial on Textual Entailment (by Sebastian Pado). The first part of the tutorial will cover the basic premises behind, and sketch the current state of, research in textual entailment. The second part of the tutorial will report more specifically on the current work of the EU project EXCITEMENT whose goal is to alleviate the fragmentation of work in the area of textual entailment through the design and implementation of a component-based, multilingual, open-source framework, the EXCITEMENT Open Platform (EOP).
    The tutorial is avalable online: Introduction & Applications; Algorithms; Knowledge; EXCITEMENT Open Platform.
  • Tutorial on Corpus Patterns: Patrick Hanks, Elisabetta Jezek and Octavian Popescu will focus on Corpus Patterns (theoretical and computational aspects of corpus pattern analysis, sense-stable patterns, chain clarifying relationships, frames, argument structures).


Panels
Distributional Semantics Panel 
In this panel we focused on two main questions and we search for possible research directions for addressing them.
- What is the relation between classic distributional semantic modelsvand the new generation of "embeddings" constructed by training deep neural networks?
  • Are these qualitatively different models, or just a new implementation of the basic idea? Is there clear evidence that embeddings are better than traditional models in fair comparisons?
  • Are there specific tasks that only these approaches can tackle?
  • What are their levels of explanatory adequacy, if they are taken as models of the way humans use language?
-Are there many types of similarity?
  • Current distributional semantics models are good at giving a global similarity score between words or phrases. However, we know that things can be similar or dissimilar in different respects: "lions" and "stone lions" are similar in shape, often not so similar in size, very different in function; "unicorns missed Noah's boat" and "unicorns didn't miss Noah's boat" are very similar in form (they are 'about' the same situation), very different in consequences. But how should we go about distinguishing different types of similarity?
  • Could there be, for instance, as many similarities as there are 'qualia', in Pustejovsky's sense? Or should we have asmany similarities as there are properties? ("A and B are similar in {size, color, origin, value ...}").
  • How shall we define and extract these different similariety types in a computationally viable way?
