Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0048] The purpose of the present invention is to provide a method and system for determining the confidence degree of open source information in the field of national defense science and technology. Through the mutual verification of the same open source information in different information sources, the confidence degree of the information and the confidence degree index of the information source are calculated to solve the problem. Users cannot judge the reli...

Abstract

The invention discloses a method and system for determining the confidence degree of open source information in the field of national defense science and technology. The method extracts the corresponding named entities and corresponding attributes by performing named entity recognition and attribute extraction on the existing open source information in the field of national defense science and technology; and further distinguishes the named entities and corresponding attributes through entity unification and entity disambiguation technology Corrections to improve the accuracy of entity and attribute extraction. In actual use, through the mutual confirmation of the same attribute of the same entity in different information sources, the confidence degree of the open source information and the confidence degree of the information source are calculated to provide more accurate information services for users in the field of defense science and technology.

Description

technical field [0001] The invention relates to the technical field of information confidence evaluation and analysis, in particular to a method and system for determining the confidence degree of open source information in the field of national defense science and technology. Background technique [0002] Open source information refers to information that can be obtained from public or semi-public channels. In the process of processing open source information, the attributes of a certain entity may have different manifestations in different information sources, such as an article (information) It is recorded that the length (attribute) of a certain type of equipment (entity) is 26 meters, while another article records that the length of this type of equipment is 20 meters. In this case, the user has no way of judging which of the two articles provides data is more accurate and reliable. The field of national defense science and technology pays special attention to the accu...
