Embodiment Construction

[0014] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0015] The concept of knowledge network was first proposed by a psychologist E. Gagne in 1985. Since then, in the field of information management, many scholars have studied the definition, classification, structure and other aspects of knowledge network. In the field of computer science, research mainly focuses on the knowledge graph of a single scientific field or multiple scientific fields, including the construction, visualization, and structura...

Abstract

The invention discloses a knowledge network building method for financial news. The knowledge network building method for financial news includes that acquiring different financial news data from a news website or a database; using a classification technique to identify the industry label of each acquired news data, using an improved topic model to extract the topic information thereof, building upstream and downstream relationship networks between industries, and creating corresponding news knowledge bases; building corresponding knowledge sub-networks based on the news knowledge bases, wherein each knowledge sub-network comprises four layers of topological structures, to be specific, each knowledge sub-network comprises four kinds of type nodes (news, news cluster, topic cluster and topic) and two kinds of type relationships (inclusion relationship and correlation). Each piece of news would generate the knowledge sub-network thereof, and the knowledge sub-network of each piece of news would be displayed below the news content. The high timeliness of different news can be guaranteed from extracting to displaying based on the built knowledge network; the knowledge network building method for financial news brings better experience to users.

Description

technical field [0001] The invention relates to the technical field of network information processing, in particular to a knowledge network construction method for financial news. Background technique [0002] At present, we are in an era of information explosion. As a major financial information push method, financial news cannot avoid problems such as large amount of data, complexity, and redundancy. In this context, many financial news retrieval platforms have emerged, including common search engines such as Baidu News and Google News, as well as financial portals such as Sina Finance and China Economic Net. On these platforms, users can use keyword search or category navigation to find the financial news content they are interested in. [0003] However, for staff in the financial field or some financial enthusiasts, the current way of obtaining financial information is still cumbersome. If a user wants to know the reasons for it and its possible consequences after read...
