The invention discloses a declarative knowledge construction method and device for semantic and situational knowledge collaborative modeling,
computer equipment and a readable storage medium, and relates to the field of
data processing.The method comprises the steps that firstly, a multi-
modal document is analyzed, a chapter abstract is extracted, and
structured content is obtained; entities, events and multi-
modal knowledge points are extracted from the
structured content, and cross-
modal fusion is carried out on the entities, the events and the multi-modal knowledge points; carrying out anaphora resolution based on the fused knowledge points, and constructing a double atlas containing a knowledge atlas, a affair atlas and a four-dimensional relation triple; clustering the double maps to obtain a theme
community, and performing
association mapping on the
community, the triple and the entity event, the chapter abstract and the multi-modal knowledge point to form association knowledge; vectorizing the associated knowledge and establishing a vector knowledge index; and carrying out
compression ratio and accuracy evaluation on the knowledge through an
evaluation system, and feeding back and optimizing the whole knowledge construction process. According to the method, multi-modal knowledge deep fusion and semantic scene collaborative modeling are realized, and the knowledge structuring degree and the application reliability are improved.
