In this paper we analyze data collected from three of the biggest Hungarian bittorrent based filesharing communities between 2008 May-June, and Hungarian cinema distribution data from the same period. We asked if the number of downloads for any given film correlates with ticket sales, revenues, the number of cinemas where the film was shown or any other statistical data on the traditional movie...

To create the first Hungarian WSD corpus, 39 suitable word form samples were selected for the purpose of word sense disambiguation. Among others, selection criteria required the given word form to be frequent in Hungarian language usage (frequency rates available in the Hungarian National Corpus (HNC) were used for measurement (Váradi, 2000)), and to have more than one sense considered frequent...

During the development of the Hungarian WordNet we found that the primarily hierarchical structure of the Princeton WordNet (PWN) had to be expanded in order that it could be used for a more accurate representation of relations among verbal meanings in Hungarian, as well. Treating verbs as eventualities we made some aspectual information explicitly available in the representation of verbs. Usin...

This paper presents recent results of the ongoing project aimed at creating the nominal database of the Hungarian WordNet. We present 9 different automatic methods, developed for linking Hungarian nouns to WN 1.6 synsets. Nominal entries are obtained from two different machine-readable dictionaries, a bilingual EnglishHungarian and an explanatory monolingual (Hungarian). The results are evaluat...

In this paper Brill’s rule-based PoS tagger is tested and adapted to Hungarian. It is shown that the present system does not obtain as high accuracy for Hungarian as it does for English because of the structural difference between these languages. Hungarian has rich morphology, is agglutinative with inflectional characteristics and has free word order. The tagger has the greatest difficulties w...

We propose a new algorithm for the classical assignment problem. The algorithm resembles in some ways the Hungarian method but differs substantially in other respects. The average computational complexity of an efficient implementation of the algorithm seems to be considerably better than the one of the Hungarian method. In a large number of randomly generated problems the algorithm has consist...
