    Impact of feature selection for corpus-based WSD in Turkish
    (2006) Orhan Z.; Altan Z.
    Word sense disambiguation (WSD) is an important intermediate stage for many natural language processing applications, The senses of an ambiguous word are the classification of usages for that word. WSD is basically a mapping function from a context to a set of applicable senses depending on various parameters. Resource selection, determination of senses for ambiguous words, decision of effective features, algorithms, and evaluation criteria are the major issues in a WSD system, This paper deals with the feature selection strategies for word sense disambiguation task in Turkish language, There are many different features that can contribute to the meaning of a word. These features can vary according to the metaphorical usages, POS of the word, pragmatics, etc, The observations indicated that detecting the critical features can contribute much than the learning methodologies. © Springer-Verlag Berlin Heidelberg 2006.

    Word sense disambiguation for semantic applications
    (2006) Orhan Z.; Altan Z.
    Natural language processing (NLP) has become the most significant obstacle that has been restricting the applications via the web. Today, very little of the content on the web can be understood by the machines, although vast amount of electronic information has been kept on them. Word sense disambiguatio (WSD) is an important intermediate step in many language processin applications. It is basically a mapping function from the context to the set of senses. This function has many parameters that are difficult to explore. The factors effecting the success of WSD systems are generally very sensitive to these parameters. The issues in WSD are examined in the context of Turkish WSD application. Ambiguous words and their sense classifications have been establishe and by providing manually sense tagged corpora and examining WSD problem from various perspectives, an important contribution has been achieved for the researches in this domain.
