Non-compositional expressions present a special challenge to NLP applications. We present a method for automatic identification of non-compositional expressions using their statistical properties in a text corpus. Our method is based on the hypothesis that when a phrase is non-composition, its mutual information differs significantly from the mutual informations of phrases obtained by substitut...

This paper describes our submission to the TREC 2011 microblog task. For the experiments, we use our new self-index search engine, NeWT, to support ranked search in the Twitter document corpus. We use a combination of phrase queries and degrading conjunctive Boolean intersection to improve retrieval effectiveness. Keywords-self-index; full-text search, phrases, threshold; intersection

A hierarchical framework is proposed to address the issues of modeling different type of words in keyword spotting (KWS). Keyword models are built at various levels according to the availability of training set resources for each individual word. The proposed approach improves the performance of KWS even when no training speech is available for the keywords. It also suggests an easier way to co...

Using the discrete logarithm in [7] and [9] a large family of pseudorandom binary sequences was constructed. Here we extend this construction. An interesting feature of this extension is that in certain special cases we get sequences involving points on elliptic curves. 2000 AMS Mathematics Subject Classification: 11K45. List of keywords and phrases: pseudorandom, elliptic curve.

We participated at the Monolingual Bulgarian QA task at CLEF-2006 with a definition extraction system based on linguistic templates and keywords. Our system uses a partial syntactic parser for Bulgarian to detect noun phrases as candidates for definitions. Our system answered correctly to 28% of the definition questions.
