Embodiment 1
[0051] Example 1: as Figure 1-3 As shown in Figure 1, the decomposing semantic parsing method of question sentences fused with factual texts, firstly, the present invention converts the triples in the knowledge base into factual textual information described in natural language, constructs a factual text base, and uses the attention mechanism to obtain Richer knowledge representation as auxiliary information. Secondly, the semantic parsing process of complex questions is divided into three stages. In the first question decomposition stage, the complex question is decomposed into a series of simple sub-question sequences; in the second information extraction stage, the original question and sub-question sequence are analyzed. Information extraction and integration are performed to obtain key information; in the third semantic analysis stage, corresponding structured query statements are generated.
[0052] As a further scheme of the present invention, the concrete steps are a...
