Semantic Web and Natural Language – Learning by Reading Text

Abstract 
Machine reading is about learning knowledge by reading text and adding it to the already existing knowledge. Such learned knowledge is represented in an ontology-schematic triplet, for which the semantic web community has developed a distributed linked data web who is interpretable by machine. A triplet as a factual knowledge is to represent a relation between two entities under a given ontology schema for a unit of knowledge base. This talk is to introduce a whole process of machine reading in two facets of knowledge extraction and graph construction. knowledge extraction is a process based on natural language processing while graph construction is to handle with knowledge graph, a usual data structure of knowledge base. Such learning process could be iteratively evolved based on the growing knowledge with reducing the noise of erroneously learned knowledge unit. Issues and utilization will be proposed.
