How to pronounce my name
 


I have just submitted my PhD at the Department of Computer Science, Bar-Ilan University, under the supervision of Ido Dagan and Jacob Goldberger.
My research field is Natural Language Processing and I am a part of the NLP lab at Bar Ilan university. My main research interest is semantic Inference. I develop algorithms for the acqusition of lexical semantic relations, propose methods for the integration of knowledge reasources and build probabilistic models for inference at the lexical level.

Demos & Downloads

  • PLIS: a Probabilistic Lexical Inference System
    Enter a Text and a Hypotheis, choose your knowledge resources, set a transitivity limit and get the entailment probability.
    The inference system is based on our line of reasearch including Shnarch et. al (2011a; 2011b; 2012, 2013).
    go to demo

  • M-PLM: a Probabilistic Lexical Model for Ranking Textual Inferences
    A Java package of the probabilistic model for textual inference, described in Shnarch et al. (2012), which uses lexical knowledge only.
    This model is the current back end of PLIS.
    More information and download.

  • Lexical entailment annotations
    Manuall annotations of the various lexical entailment phenomena in a sample from RTE-5 pilot task.
    We have randomly sampled text-hypothesis pairs from the development set, 100 from the positive examples and another 100 from the negative. Each (T,H) pair was manually annotated for all lexical entailments between terms of the text and terms of the hypothesis.
    More information and download.

  • WikiRules!
    A large scale lexical resource automatically extracted from Wikipedia.
    The algorithm to aoutomatically extract this rule-base from Wikipedia is described in Shnarch et. al (2009).
    Coming soon, WikiRules 2.0! A new and improved version of the rule base and the code to extract entailment rules from Wikipedia.
    More information and download.
