Description

Abstract: 

In this talk, we will review some of the recent applied text mining work at Dalhousie. We will argue the need for a text representation that would be more linguistically informed than the standard vector model. We will present one such proposal, in which a co-occurrence model takes into account the distribution of words throughout the corpus. We will then show how this representation is successfully applied in the task of categorizing dream descriptions by their emotional valuation (joint work with J. De Koninck and A. Razavi, Ottawa). We will round up the talk with our experience with some of the other text mining techniques used in the analysis of the twitter traffic in the 2012 presidential elections in France and in the US (joint work with LIRMM, France).
