Hot topic tracing method and device based on knowledge graph

Abstract

The invention discloses a hot topic tracing method and device based on a knowledge graph, and the method comprises the steps: obtaining the event information of one or more information events relatedto a to-be-traced hot topic, wherein the to-be-traced hot topic is associated with one or more information events, and each information event is associated with one or more pieces of information; according to the event information of each information event associated with the to-be-traced hot topic, searching one or more historical information events associated with the to-be-traced hot topic froma pre-constructed knowledge graph, the knowledge graph comprising an association relationship between each hot topic and each information event; collecting information related to each information event and historical information event associated with the hot topic to be traced; and outputting information associated with each information event and historical information event associated with the to-be-traced hot topic. According to the invention, historical similar information events associated with the to-be-traced hot topic can be searched based on each information event associated with theto-be-traced hot topic.

Description

technical field [0001] The present invention relates to the field of the Internet, in particular to a method and device for tracing hot topics based on knowledge graphs. Background technique [0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. The descriptions herein are not admitted to be prior art by inclusion in this section. [0003] With the rapid development of the Internet, the amount of information that users can obtain through the Internet has shown explosive growth. In order to improve the reading efficiency of information content and quickly extract effective information, one or more Hot topics, enabling users to quickly trace the information related to the hot topics they care about. However, with the accumulation of historical hot topic information data, for a certain hot topic, in addition to the information information of one or more news events directly related to the hot topic ...

Problems solved by technology

[0006] The embodiment of the present invention provides a method for tracing hot topics based on knowledge graphs, which is used to solve the problem that the existing information platform realizes the traceability of historical information information by searching for keywords, which leads to the efficiency of information traceability on a certain hot topic Low, the technical problem of incomplete information, the method includes: obtaining the event information of one or more information events associated with the hot topic to be traced, wherein, the hot topic to be traced is associated with one or more information events, and each information event is associated with one or multiple pieces of information; according to the event information of each information event associated with the hot topic to be traced, find one or more historical information events associated with the hot topic to be traced from the pre-built knowledge graph, wherein the knowledge graph contains: each hotspot The relationship between the topic and each information event; collect the information information associated with each information event and historical information event associated with the hot topic to be traced; output the information information associated with each information event associated with the hot topic to be traced and historical information event

[0007] The embodiment of the present invention also provides a hot topic tracing device based on a knowledge map, which is used to solve the problem that the existing information platform realizes the tracing of historical information information by searching for keywords, which leads to the tracing of information information on a certain hot topic For technical problems of low efficiency and incomplete information, the device includes: a hot topic information query module, which is used to obtain event information of one or more information events associated with the hot topic to be traced, wherein the hot topic to be traced is associated with one or more Information event, each information event is associated with one or more information; the knowledge graph search module is used to find a hot topic associated with the hot topic to be traced from the pre-built knowledge graph according to the event information of each information event associated with the hot topic to be traced or multiple historical information events, wherein, the knowledge map includes: the association relationship between each hot topic and each information event; the hot topic information information collection module is used to collect hot topics to be traced to correlate each information event and historical information event association The hot topic information information output module is used to output the hot topics to be traced and the information associated with each information event and historical information event.

[0008] The embodiment of the present invention also provides a computer device, which is used to solve the problem that the existing information platform realizes the traceability of historical information information by searching for keywords, which leads to low efficiency and incomplete information traceability of information information on a hot topic technical problem, the computer device includes a memory, a processor, and a computer program stored on the memory and operable on the processor. When the processor executes the computer program, the above hot topic tracing method based on the knowledge map is realized.
