Abstract

The Web of Data is based on two simple ideas: to employ the RDF data model to public structured data on the Web and to set explicit RDF links to interlink data items within different data sources. In this paper, we describe our experience in building a system of link discovery between KAKEN, a database provides the latest information of research projects in Japan, and the DBLP Computer Science Bibliography. Using these links one can navigate from the information of a computer scientist in KAKEN to his publications in the DBLP database. Our problem of linkage between KAKE researchers and DBLP authors is name disambiguation. We proposed combining LDA based topic model and co-author network approach to improve linkage accuracy.
