Semantic Similarity Methods in Folksonomies
Kadlec, Jan ; Otrusina, Lubomír (referee) ; Schmidt, Marek (advisor)
Bakalářská práce byla vypracována na studijním pobytu na "Aalborg University" v Dánsku, a byla zpracována v angličtině. Folksonomie jsou nový, uživateli řízený přístup ke klasifikaci a důležitá čast Web 2.0. Jsou také jediným přístupem, který je schopen udržet krok s dnešní rychlostí expanze webu, tím že předá uživatelům odpovědnost za klasifikaci. Pokud folksonomie obsahují dostatečné množství dat, dají se k mnohému využít. Tato práce se zaměřuje na metody sémantické podobnosti ve folksonomiích. Cílem této práce bylo odzkoušet mnohé metody na vzorku tří datových sad - delicious.com, Last.fm a medworm.com. Toto bylo vykonáno za pomocí kotvících dat z WordNetu, Open Directory Project a zdravotně orientované ontologie. Výsledky přinesené touto prací indikují, že metody sémantické podobnosti mohou být použity k úspěšnému měření podobností v mnohých doménách.

Semantic Relatedness of Scientific Articles
Dresto, Erik ; Schmidt, Marek (referee) ; Otrusina, Lubomír (advisor)
The main goal of the thesis is to explore basic methods which can be used to find semantically related scientific articles. All the methods are explained in detail, compared and in the end evaluated by the standard metrics. Based on the evaluation, a new method for computing semantic similarity of scientific articles is proposed. The proposed method is based on the current state-of-the-art methods and adds the another important factor for computing similarity - citations. Using citations is important, since they represent a static bond between the articles. Finally, the proposed method is evaluated on the real data and compared with other described methods.

Encyclopedia Expert
Krč, Martin ; Schmidt, Marek (referee) ; Smrž, Pavel (advisor)
This project focuses on a system that answers questions formulated in natural language. Firstly, the report discusses problems associated with question answering systems and some commonly employed approaches. Emphasis is laid on shallow methods, which do not require many linguistic resources. The second part describes our work on a system that answers factoid questions, utilizing Czech Wikipedia as a source of information. Answer extraction is partly based on specific features of Wikipedia and partly on pre-defined patterns. Results show that for answering simple questions, the system provides significant improvements in comparison with a standard search engine.
