Embodiment 1
[0065] The specific process of a textual relationship extraction method that combines multi-level information extraction and noise reduction is as follows: figure 1 shown. The present embodiment has described the flow process and the overall framework of the method of the present invention, respectively as figure 1 and figure 2 shown. During specific implementation, the method of the present invention can be applied to extract triplet information in discourse data, and update the knowledge of the knowledge map. The reason why chapter relationship extraction is important is that the existing structured knowledge accounts for a small proportion of existing knowledge, while real-world knowledge usually exists in the form of chapters, and it is still growing rapidly. Manually constructing structured knowledge requires a lot of time and money, and it is difficult for manual methods to keep up with the speed of knowledge growth.
[0066] The data used in this example comes from...
