Abstract and Keywords
The article provides a theoretical background of anaphora and introduces the task of anaphora resolution. The importance of anaphora resolution in natural language parsing (NLP) is distinct, and early work and recent developments are outlined in this article. Finally, issues that need further attention are discussed. Anaphora is the linguistic phenomenon of pointing back to a previously mentioned item in the text. Varieties of anaphora include pronominal anaphora, lexical noun phrase anaphora, and nominal anaphora. The interpretation of anaphora is crucial for the successful operation of a machine translation system. It is essential to resolve the anaphoric relation when translating into languages that mark the gender of pronouns. Finally, the article suggests that the last years have seen considerable advances in the field of anaphora resolution, but there are still a number of outstanding issues that either remain unsolved or need further attention.
