A Novel Knowledge - engineering based approach for anaphora resolution of Tamil pronouns

This paper discusses the problem of anaphora resolution that needs to be solved for efficient parsing of Tamil sentences and proposes a knowledge-engineering methodology to resolve it. Syntax is the scientific study of sentence structure. The sentences are hierarchically structured. The sentence is not just a linear string of symbols. The position of the words, relative to one another, makes a difference in the meaning of the sentence. Such a feature gives rise to certain problems. Anaphora resolution is one among them. This paper gives a guideline to extract the necessary grammatical and semantic information for imposing selectional restriction rules. This paper suggests an efficient way of combining Ontology and Wordnet to arrive at a new concept Ontnet which will facilitate word sense disambiguation as well as anaphora resolution.
