Abstract
The present invention provides an apparatus and method for automatic generation and update of a knowledge graph from multi-modal sources. The apparatus comprises a conversation parsing module configured for updating a dynamic information word set VD with labelled words generated from extracted from the multi-modal sources; updating a static information word set VS based on extracted schema of relations extracted from the multi-modal sources; and generating pairs of question and answer based on the dynamic information word set VD, the static information word set VS and the one or more sentence patterns; and a knowledge graph container configured for updating a knowledge graph based on the extracted entities of interest and schema of relations. Therefore, an efficient and cost-effective way for question decomposition, query chain construction and entity association from unstructured data is achieved.
