Embodiment 1
[0058] This embodiment provides a method for pushing marine industry news based on knowledge graphs, such as figure 1 , figure 2 As shown, the method includes the following steps:
[0059] S1: Build a knowledge map and a news database in the marine industry;
[0060] S2: Obtain the query intent according to the query information input by the user;
[0061] S3: Input the query intent obtained in S2 into the marine industry domain knowledge map constructed by S1 to perform element query and obtain related words; use the related words as user interest terms;
[0062] S4: Extract keywords from each piece of marine industry news in the marine industry news database constructed in S1, and obtain the keyword term of each piece of marine industry news;
[0063] S5: Carry out a correlation score between the user interest term obtained in S3 and each keyword term obtained in S4, and obtain a corresponding correlation score;
[0064] S6: Sort the marine industry news by using the re...
Embodiment 2
[0092] This embodiment provides a marine industry news push system based on knowledge graphs, such as Figure 4 As shown, the system includes:
[0093] The user module is used for users to input query information, and to display pushed marine industry news for users to click and read;
[0094] The data analysis module is used to obtain query intent according to the query information input by the user;
[0095] The knowledge map module is used to obtain the user's interest items according to the query intention when the user first queries; when the user clicks to read the pushed marine industry news, it is used to obtain the secondary information of the comprehensive query intention and the read marine industry news user interest terms;
[0096] The news base module is used to store marine industry news information, form a news base in the marine industry field, and extract keyword terms for each piece of marine industry news information;
[0097] The scoring and sorting mod...

Abstract
The invention provides a marine industry news pushing method based on a knowledge graph. The marine industry news pushing method comprises the following steps: S1, constructing a marine industry domain knowledge graph and a marine industry domain news library; s2, obtaining a query intention according to query information input by a user; s3, inputting the query intention into the marine industry domain knowledge graph for element query to obtain user interest lexical items; s4, extracting a keyword lexical item of each part of marine industry news; s5, performing relevancy scoring on the user interest lexical items and the keyword lexical items to obtain relevancy scores; s6, sorting the marine industry news by taking the relevancy score as a sorting standard, and pushing the sorted marine industry news to the user; and S7, after the user clicks reading, performing secondary information extraction on the read news, superposing the secondary information and the query intention to serve as a secondary query intention, and executing S3S6. The news conforming to the interest points of the user can be accurately pushed to the user to be read by the user, and convenience is brought to the user.
Description
technical field [0001] The present invention relates to the technical field of natural language processing, and more specifically, to a method and system for pushing marine industry news based on knowledge graphs. Background technique [0002] With the advent of the Internet and the era of big data, a variety of information has been generated. The marine industry economy is an important content of today's marine economic research. In recent years, the marine economy has developed vigorously, accelerated the transformation of the economic development mode, and enhanced the vitality and efficiency of economic growth, which has played a huge role in the stability and employment of the national economy. For users, it is difficult to obtain relevant knowledge. If they cannot obtain and understand information in a timely manner, they may not be able to make accurate decision-making judgments. Strengthening the deep integration of information technology and marine industry is an im...
