dc.description.abstractStatistical analysis of parliamentary roll call votes is an important topic in political science because it reveals ideological positions of members of parliament (MP) and factions. However, it depends on the issues debated and voted upon. Therefore, analysis of carefully selected sets of roll call votes provides a deeper knowledge about MPs. However, in order to classify roll call votes according to their topic automatic text classifiers have to be employed, as these votes are counted in thousands. It can be formulated as a problem of classification of short legal texts in Lithuanian (classification is performed using only headings of roll call vote). We present results of an ongoing research on thematic classification of roll call votes of the Lithuanian Parliament. The problem differs significantly from the classification of long texts, because feature spaces are small and sparse, due to the short and formulaic texts. In this paper we investigate performance of 3 feature representation techniques (bag-of-words, n-gram and tf-idf) in combination with Support Vector Machines (with different kernels) and Multinomial Logistic Regression. The best results were achieved using tf-idf with SVM with linear and polynomial kernelsen
