Document classification based on the lexical-semantic network, wordnet, is presented. Two types of document classification in Serbian have been experimented with – classification based on chosen concepts from Serbian WordNet (SWN) and proper names-based classification. Conceptual document classification criteria are constructed from hierarchies rooted in a set of chosen concepts (first case) or in hierarchies rooted in some of the proper names' hypernyms (second case). A classificator of the first type is trained and then tested on an indexed and already classified Ebart corpus of Serbian newspapers (476917 articles). Precision, recall and F-measure show that this type of classification is promising although incomplete due mainly to SWN incompleteness. In the context of proper names-based classification, a proper names ontology based on the SWN is presented in the paper. A distance based similarity measure is defined, based on Euclidean and Manhattan distances. Classification of a subset of Contemporary Serbian Language Corpus is presented.
