Research on Temporal Information Retrieval Method Based on Data Graph

The traditional information retrieval technology is not concerned about the information temporal, but the temporal nature of the data is playing a particularly important role in some fields, so the search of temporal information has become a hot spot. With the relational database information retrieval technology emerge, it is urgent to integrate temporal attributes into the relational database information retrieval technology. In this paper, temporal information retrieval method based on data graph is proposed, and the validity of the method is verified by experiments.
