In this paper Brill's rule-based PoS tagger is tested and adapted for Hungarian. It is shown that the present system does not obtain as high accuracy for Hungarian as it does for English (and other Germanic languages) because of the structural difference between these languages. Hungarian, unlike English, has rich morphology, is agglutinative with some inflectional characteristics and has fairl...

The relation between vowel formants and subglottal resonances (SGRs) has previously been explored in English, German, and Korean. Results from these studies indicate that vowel classes are categorically separated by SGRs. We extended this work to Hungarian vowels, which have not been related to SGRs before. The Hungarian vowel system contains paired long and short vowels as well as a series of ...

In this paper, we describe and evaluate different general stemming approaches for the French, Portuguese (Brazilian), German and Hungarian languages. Based on the CLEF test-collections, we demonstrate that light stemming approaches are quite effective for the French, Portuguese and Hungarian languages, and perform reasonably well for the German language. Variations in mean average precision amo...

The paper describes our participation in Monolingual tasks at CLEF 2007. We submitted results for the following languages: Hungarian, Bulgarian and Czech. We focused on studying different query expansion techniques: Probabilistic Relevance Feedback (PRF) and Mutual Information Relevance Feedback (MI-RF) to improve retrieval performance. After an analysis of our experiments and of the official r...

Ji et al. have conjectured that using the matrix form (to represent a basic solution) instead of the Simplex tableau in the dual Simplex method will lead to an algorithm with the time complexity comparable to the Hungarian algorithm for solving the Assignment Problem. In this note we show that both the time complexity and the CPU times of the Ji et al. algorithm are far away from being competit...

On 18 May the Hungarian Red Cross celebrated the centenary of its foundation and International Review has the pleasure of publishing a summary of its history, written by the President of its Executive Committee, Mr. Jdnos Hantos. International Review extends its congratulations and best wishes to the Hungarian Red Cross and its most sincere thanks to Mr. Jdnos Hantos for his contribution to thi...

The paper reports on work in progress to develop a tag set for Hungarian. The rich morphological structure of the language makes tagging feasible only after a full-scale morphological analysis, which results in a magnitude of patterns that do not easily translate into a corpus tag set of manageable size. The paper analyses the extent and types of morpho-syntactic ambiguity found in a 21m word s...

Carniolan honey bees (Apis mellifera carnica) are considered as an indigenous subspecies in Hungary adapted to most of the ecological and climatic conditions in this area. However, during the last decades Hungarian beekeepers have recognized morphological signs of the Italian honey bee (Apis mellifera ligustica). As the natural distribution of the honey bee subspecies can be affected by the imp...
