Abrir at Ntcir-9 Geotime Task Usage of Wikipedia and Geonames for Handling Named Entity Information - scientific work related to Wikipedia quality published in 2011, written by Masaharu Yoshioka.

Overview

In the previous NTCIR8-GeoTime task, ABRIR (Appropriate Boolean query Reformulation for Information Retrieval) proved to be one of the most effective systems for retrieving documents with Geographic and Temporal constraints. However, failure analysis showed that the identification of named entities and relationships between these entities and the query is important in improving the quality of the system. In this paper, authors propose to use Wikipedia and GeoNames as resources for extracting knowledge about named entities. Authors also modify system to use such information.
