چکیده
This paper presents the HITSZ-PolyU system in the CIPS-SIGHAN bakeoff 2012 Task 3, Chinese Personal Name Disambiguation. This system leveraged the Chinese encyclopedia Baidu Baike (Baike) as the external knowledge to disambiguate the person names. Three kinds of features are extracted from Baike. They are the entities’ texts in Baike, the entities’ work-of-art words and titles in the Baike. With these features, a Decision Tree (DT) based classifier is trained to link test names to nodes in the NameKB. Besides, the contextual information surrounding test names is used to verify whether test names are person name or not. Finally, a simple clustering approach is used to group NIL test names that have no links to the NameKB. Our proposed system attains 64.04% precision, 70.1% recall and 66.95% F-score.

Attribute based Chinese Named Entity Recognition and Disambiguation
In this paper, we briefly report our system for Chinese Named Entity Recognition and Disambiguation task in CIPS-SIGHAN joint conference. We first present a method to extract different types of target person attributes from text documents with multiple techniques. Then we use these attributes to disambiguate different entities. Finally a classifier is used to distinguish entities in the knowled...

متن کاملUC3M_13: Disambiguation of Person Names Based on the Composition of Simple Bags of Typed Terms
This paper describes a system designed to disambiguate person names in a set of Web pages. In our approach Web documents are represented as different sets of features or terms of different types (bag of words, URLs, names and numbers). We apply Agglomerative Vector Space clustering that uses the similarity between pairs of analogous feature sets. This system achieved a value of 66% for Fα=0.2 a...
