Research and Application on Geoscience Literature Knowledge Discovery Technology

Based on the characteristics of geoscience literature, this paper designs a knowledge discovery technology framework, which consists of data preprocessing, relationship extraction and visual presentation. The main technical features are the use of dictionary-based maximum reverse matching word segmentation algorithm and the selection of the statistical language model based relationship extraction method. Finally, a distributed computing environment was built in the experiment, and the Mapping knowledge domain of the goldfield was constructed so that the feasibility of the technical framework was verified by experiments.
