Knowledge Graph for Historical Primary Sources and the Extension of Factoid model

Abstract

The use of knowledge graph technologies has been developed recently in historical studies, especially in the fields of prosopography or biography. The materials used in these studies, however, are mostly brought by secondary findings which have been given by the traditional research methods. This means that these studies do not necessarily deal with primary-source documents. Nevertheless, if we pursue more useful and profound application of knowledge graph technologies into historical studies, it should be necessary to consider the way to describe the very contents of primary-source documents. Although Factoid model already makes this kind of description partially possible, it is still not sufficient to express the chronological context and ambiguity which we find quite often in historical documents. Therefore, in this paper, we first propose the extension of the Factoid model with which we are now able to describe the ambiguous chronological context, and then introduce our data, constructed from ancient historical documents, and query examples.
