Embodiment 1

[0116] The hypernyms to be processed are: "the works of the poet Chen Xiangyan", "the works of the poet Mei Shaojing", "the works of the poet Zhao Gong", "the works of the poet Lu Zhi" and "the works of the poet Wang Yi".

[0117] Although these hypernyms to be processed look similar, the actual key information is inconsistent. Therefore, after removing similar text parts, the remaining text parts are: Chen Xiangyan, Mei Shaojing, Zhao Gong, Lu Zhi, Wang Yi.

[0118] The semantic similarity between the above remaining text parts is lower than the third preset threshold, and the average number of words contained is about 2.4, which is higher than the fourth preset threshold "2.2", which means that this aggregation is invalid, and these hypernyms to be processed Aggregation cannot be performed.

Embodiment 2

[0120] The hypernyms to be processed are: "simple homemade steamed dumplings", "homemade steamed dumplings" and "" steamed dumplings". After removing similar text parts, stop words and plural words, the remaining text parts are: NULL, NULL and NULL .

[0121] If the rest of the above text is empty, it means that the aggregation is valid, and these hypernyms to be processed can be merged.

[0122] Further, after it is determined that a group of hypernyms to be processed can be aggregated, the largest common character string between each hypernym to be processed in the aggregated group of hypernyms to be processed can be used as the aggregation of the group of hypernyms to be processed after the name.

[0123] For example: "simple homemade steamed dumplings", "homemade steamed dumplings" and "steamed dumplings", among them, the largest common character string: steamed dumplings, steamed dumplings can be used to name the hypernyms to be processed after aggregation, and these are...

Abstract

The present invention relates to the information processing technology, and in particular, to a hypernym aggregation method and apparatus, in order to improve the accuracy of hypernym aggregation. Themethod comprises that: a terminal device calculates the word vector similarity between the hypernyms according to the word vectors contained in each hypernym, calculates the entity type similarity between the hypernyms according to the entity types associated with the entities corresponding to each hypernym, and aggregates each hypernym with the word vector similarity reaching the first preset threshold and the entity type similarity reaching the second preset threshold. Thus, according to the technical scheme of the present invention, the short text such as the hypernym can be effectively processed, so that not only text key information contained in the hypernym can be effectively excavated, but also the type characteristics of the hypernym can be accurately described; and at the same time, the complicated workload of the artificial design of the characteristics can be avoided, and the generalization ability of the model can be enhanced, so that the invalid hypernym can be effectively identified, redundant data in the hypernym can be removed, and the accuracy of the hypernym aggregation can be significantly improved.

Description

technical field [0001] The present invention relates to information processing technology, in particular to a hypernym aggregation method and device. Background technique [0002] In the hypernym network generated based on the knowledge graph, in order to avoid the problem of hypernym redundancy, it is usually necessary to aggregate hypernyms with the same semantic meaning, that is, extract and merge hypernyms with different expressions for the same semantic meaning. For example: hypernyms about SLR cameras include: "a SLR camera", "commonly known as a SLR camera", "SLR camera", "LR camera", etc. These hypernyms with the same semantic meaning but different descriptions are called the same Semantic hypernyms. The process of merging these same semantic hypernyms together and expressing them with a common name is called the aggregation process of hypernyms. Merging hypernyms with the same semantics can reduce the redundancy problem of the hypernym network and improve the qual...
