Abstract

The disclosure relates to a construction method and device for a chemical knowledge graph, an intelligent question answering method and device for chemical knowledge, and two computer-readable storage media. The construction method comprises the following steps: obtaining knowledge data in chemical industry field; pre-processing the knowledge data to obtain entity data and property data related to chemical knowledge; determining a preliminary knowledge representation according to the entity data and the property data; performing entity alignment on the preliminary knowledge representation to obtain a standard knowledge representation; and constructing the chemical knowledge graph according to the standard knowledge representation. The construction method for a chemical knowledge graph can automatically collect relevant knowledge in the chemical industry to construct a chemical knowledge graph on basis of natural language processing, big data and artificial intelligence technology, thereby greatly improving the construction speed of the chemical knowledge graph and reducing the manual construction cost of the chemical knowledge graph.
