Information citation analysis method and system

Abstract

The invention provides an information citation analysis method and system. The method comprises the steps that S1, obtaining a first patent A through retrieval; S2, constructing a citation patent document set Q; S3, constructing a leader patent keyword set W1, W2, W3,..., Wi,..., Wn; s4, setting a keyword set V of the first patent A; S5, sequentially calculating the similarity between each keywordin the keyword set Wi of the citation patent qi and each keyword in the keyword set V of the first patent A, and extracting the keyword with the highest similarity from the keyword set Wi of the citation patent to form a real keyword set Mi of the ith patent document qi; S6, sequentially calculating the similarity Epsilon i between the real keyword set Mi and the keyword set V of the first patentA, and judging whether Epsilon i is greater than K or not; and S7, recommending the patent documents in the set alpha to the user. The information citation analysis method and system provided by theinvention have the advantages of wide application range, high accuracy, simplicity and high efficiency.

Description

technical field [0001] The invention relates to the technical field of information analysis, in particular to an information citation analysis method and system. Background technique [0002] The analysis and research of literature or information intelligence is a kind of complex and high-intensity intellectual labor. Especially in today's era of Internet and information overload, it has become an important method in scientific and technological research to sort out the complex information, intelligence, and literature in order to obtain important support and basis for technology research and development, manufacturing, and strategic decision-making. . But in the Internet age, information is growing at an explosive rate, and it is becoming more and more difficult to find the information we really need. We urgently need a method that can help us organize and understand this huge amount of information. [0003] As a kind of public scientific and technological documents prote...

Problems solved by technology

But "citation network" types (such as figure 2 (shown) in the patent citation relationship, on the one hand, there are no core patents with particularly high citation frequency, and the citations are relatively scattered; There are also many intersections and nodes, and the whole presents a more complex network structure

For the "citation network" type of patent citation relationship, it is not enough to evaluate the importance of patents only by counting the frequency of citations, and it cannot fully reflect the status of a patent in this type of technical field, nor can it be very effective. "Follow the vines" to straighten out the development trajectory of this technology field
