Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0048] The flow charts shown in the drawings are just illustrations, and do not necessarily include all contents and operations / steps, nor must they be performed in the order described. For example, some operations / steps can be decomposed, combined or partly combined, so the actual order of execution may be changed according to the actual situation. In addition, although the functional modules are divided in the schematic diagram of the device, in some cases, they ...

Abstract

The invention relates to artificial intelligence, is applied to smart cities, and uses natural language processing to improve search precision. The invention specifically discloses a content search method and device, a domain prediction model training method and device and a storage medium, and the search method comprises the steps: obtaining a search text, and carrying out the word segmentation of the search text to extract a plurality of keywords; carrying out embedding processing on the keywords to obtain keyword vectors of the keywords; based on the trained part-of-speech tagging model, determining the part-of-speech of each keyword according to the keyword vector; based on the trained domain prediction model, determining whether the keyword is a domain word according to the keyword vector; determining a weight value of each keyword according to the part-of-speech of the keyword and whether the keyword is a domain word, the weight value of the keyword which is the domain word beinggreater than the weight value of the keyword which is not the domain word; and based on the search engine, outputting a search result according to the keyword and the weight value thereof. The invention further relates to the field of the block chain, and the trained field prediction model can be stored in the block chain node.

Description

technical field [0001] The present application relates to the technical field of natural language processing, and in particular to a content search method, a domain prediction model training method, a device, and a storage medium. Background technique [0002] In today's information age, users cannot obtain information such as courses, knowledge, news, and current events without using search tools. There is a big difference. [0003] Natural language processing is an important field in the field of artificial intelligence. For humans, basic semantic understanding is a daily necessary language ability, but for artificial intelligence, it represents the highest level of progress. Many research institutions will use natural Language processing Natural Language Processing (NLP) as a technical focus. In the field of search engines, research on using natural language processing technology to improve search performance has been continuously deployed. However, at present, the sea...
