Study on Knowledge Discovery Based on "Subject-Predication-Object" Predications: A Case Study of Induced Pluripotent Stem Cells
摘要
Abstract
This paper summarizes a set of knowledge discovery framework to make studies on knowledge discovery in biomedical literature based on Subject-Predication-Object (SPO) predications, and studies the key technology and implementation process of the framework. First, SPO predications were extracted from the biomedical literature by using UMLS corpus and SemRep;then, according to the knowledge organization system, vocabulary and cleaning rules were self-defined, the SPOs were cleaned and filtered;next, semantic network diagrams were constructed by NetMiner, which included subjects and objects as the center nodes and predications as the edges;final y, combining the diagrams and experts' interpretation, domain knowledge discovery was achieved. In this paper, an empirical study was conducted to investigate the field of pluripotent stem cel s. Research results show that, SPO predications can reveal the knowledge content of scientific literature, and SPOs-based semantic networks can intuitively support domain knowledge discovery. The framework is compatible, efficient and easy to implement.关键词
