| Outline of Final Research Achievements |
In this research, we proposed a framework to extract named entity from the text with named entity type information by using DBPedia. We also proposed facet-biased topic model that take into account the type of named entity as facet. In addition, we implemented WC3 that analyzes consistency of metadata in articles that belongs to a particular Wikipedia category. We confirmed that WC3 can find out the articles that have inconsistent metadata and candidate articles for the category.
