Among major categories of named entities (NEs, which in this paper refer to entity names, excluding the MUC time and numerical NEs), company and product names are often trademarked or uniquely registered, and hence less subject to name ambiguity. This paper focuses on cross-document disambiguation of person names. Previous research for cross-document name disambiguation applies vector space model (VSM) for context similarity, only using co-occurring words [Bagga & Baldwin 1998].
