Abstract

Noun phrase (NP) co-reference resolution is a problem involved in many Natural Language areas, such as Dialog, Information Extraction, Summarization and Question Answering, among others. Especially important issues regarding this problem are the detection of aliases and the detection and expansion of acronyms. In this sense, terminological and general gazetteers of Named Entities (NEs) being aliases and of pairs acronym-expansion can be helpful. This paper describes a methodology to acquire semi-automatically these gazetteers.
