Non-negative matrix factorisation-based verb semantics for personal pronoun resolution


Tuggener, Don; Klenner, Manfred (2012). Non-negative matrix factorisation-based verb semantics for personal pronoun resolution. In: Sixth International Conference on Semantic Computing (ICSC 2012), Palermo, 19 September 2012 - 21 September 2012.

Abstract

We present an initial utility study of a distributional model of verb selectional preferences for 3rd person
pronoun resolution in German. We investigate cases in which
3rd person pronouns occur as subjects of transitive verbs. In each such case, the likelihood of inserting one of the antecedent candidates is calculated as the conditional probability of the antecedent candidate given either the verb governing the pronoun or the object of the verb. These probabilities are estimated using a matrix derived from frequency counts in a large corpus. Non-negative matrix factorisation is applied as a sort of semantic smoothing to address the sparsity issue inherent in the approach.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
