ABSTRACT
Summarizing, extracting keywords, sorting and filtering large quantities of texts were subject of various algorithms based on lexical databases because this was a difficult and time consuming task for a human operator. Our proposed algorithm is based on WordNet lexical database. It eliminates the connection words. For the remaining words (only nouns or verbs) we build a tree with several levels of more generic terms like hypernym or lexicographer file. Using custom weights for each tree level and statistical analysis, we extract a restricted number of words which are used to define the keywords of a document. These results can be used to sort and filter a document based on relevance.

Acquisition of Hypernymy-Hyponymy Relation between Nouns for WordNet Building
IALP '10: Proceedings of the 2010 International Conference on Asian Language ProcessingAutomatic extraction of hypernym-hyponym pairs has been done in many researches. But none is described as an automatic method to incorporate the result to Word Net or on Word Net building. This paper proposes a method to automatically acquire hypernym-...
Hypernymy in WordNet, Its Role in WSD, and Its Limitations
CICSYN '15: Proceedings of the 2015 7th International Conference on Computational Intelligence, Communication Systems and NetworksThis paper closely analysed and depicted the role of the hyponymy that is used in the lexical database called the Word Net to relate the words semantically with a relation "... Is a kind of...". The relation has very important role for disambiguating ...
Exploiting noun phrases and semantic relationships for text document clustering
Text document clustering plays an important role in providing better document retrieval, document browsing, and text mining. Traditionally, clustering techniques do not consider the semantic relationships between words, such as synonymy and hypernymy. ...
