The invention relates to the technical field of
data analysis, can be applied to business scenes of
medical health, financial science and technology, culture research and the like, and discloses a multi-source
knowledge processing and querying method, which comprises the following steps:
data acquisition, cleaning and
standardization processing, and standardized
database construction; extracting core concepts and association relationships, and generating knowledge elements; constructing a multi-dimensional
knowledge graph based on knowledge elements, and establishing a semantic index to realize data
semantic annotation and bidirectional mapping; and analyzing the query intention, extracting a query constraint condition, and executing association reasoning based on the multi-dimensional
knowledge graph to generate a query result. According to the method, the standardized
database of the multi-source heterogeneous data is constructed, so that the
data consistency is improved; through multi-dimensional
knowledge graph construction and semantic index establishment, the relevance and structural expression of data are enhanced, so that the relationship between knowledge elements is clear and traceable; and through association reasoning based on query constraint conditions, the query accuracy and efficiency are improved.
