Embodiment 1

[0081] Taking the published texts including 5 categories and each category containing 2000 patents as the experimental object (patent documents to be classified), the patent classification method or system provided by the present invention is used for classification.

[0082] In this embodiment, the jieba word segmentation tool can be used to segment the description abstract of the patent document. The labeling standard of the word segmentation tool can be the labeling set of the Institute of Computing Technology, Chinese Academy of Sciences. This labeling set is relatively comprehensive, can provide assistance for natural language processing related work, and is widely used in related research. Perform onehot encoding on the part-of-speech tagging content, and encode it into a vector with a length of 50. For example, the adjective a is marked as [0,0,1,0,0,…], where a corresponds to the third position in the vector.

[0083] In this embodiment, the mapping layer may include a...

Abstract

The embodiment of the invention provides a patent classification method and system based on dual-channel feature fusion and a storage medium, belonging to the technical field of patent document classification. The patent classification method comprises: reading a patent document to be classified, mapping words and phrases of a specification abstract in the patent document to word2vec word vectorsand POS part-of-speech vectors to generate a word2vec word vector sequence and a POS part-of-speech vector sequence; processing the word2vec word vector sequence and the POS part-of-speech vector sequence to generate a first sentence vector; mapping the first sentence vectors to second sentence vectors by using a full connection layer, wherein a number of categories of the patent document, the number of nodes of the full connection layer and the dimension of the second sentence vectors are equal; normalizing the second sentence vectors by using a softmaxt classification layer.

Description

technical field [0001] The invention relates to the technical field of patent document classification, in particular to a patent classification method, system and storage medium based on dual-channel feature fusion. Background technique [0002] In recent years, scientific and technological innovation has attracted more and more attention, and patents, as an important record carrier of innovation, have also shown a trend of explosive growth. Faced with such a massive amount of patent data, manual classification requires huge labor costs, and the processing efficiency cannot meet actual needs. Therefore, the importance of research on patent automatic classification methods has become increasingly prominent, and has become an important research hotspot at the present stage. At present, the research on patent classification mostly adopts the IPC classification system. IPC classification is a hierarchical classification system, including department, class, subclass, group and o...
