AI Technical Summary

Problems solved by technology

Papers are very informative, but also highly complex and weakly structured
Although it is possible to manually read the paper and analyze the combination of the research problem and the method used in the paper, the characteristics of the paper determine that this method is inefficient. Due to the high timeliness of the paper, it is not even advisable when it is necessary to track new technologies of

Embodiment Construction

[0048] refer to figure 1 , a kind of method that the present invention proposes to extract the question method in the paper title, comprises:

[0049] Step S1, standardize the title of the paper, match the keywords of the paper in the title of the paper, and obtain a set of preliminary problem method concepts, specifically including:

[0050] S11. Convert the paper title text to lowercase, and perform word segmentation, part-of-speech tagging and part-of-speech restoration;

[0051] S12. Perform keyword matching in the paper title to obtain a preliminary set of problem method concepts.

[0052] refer to figure 2, in the specific scheme, convert the text to lowercase, for example, "A Database Architecture for Supporting Business Transactions" is converted into "a database architecture for supporting business transactions"; text word segmentation, part-of-speech tagging and part-of-speech restoration, for example, from the above example, " database architecture for support b...

Abstract

The invention discloses a method for extracting problem method pairs in the title of a paper, including: standardizing the title of a paper, matching keywords of a paper in the title of a paper to obtain a preliminary set of problem method concepts; using blacklists and whitelists Adjust the concept set of preliminary problem methods to obtain the concept set of effective problem methods; construct the set of target grammatical patterns used to separate problems and methods; extract the set of problem concepts and Method concept set; use the Cartesian product to match the problem concept set and the method concept set to obtain the problem method pair in the title of the paper.

Description

technical field [0001] The invention relates to the technical field of text information extraction, in particular to a method for extracting question and method pairs in the title of a paper. Background technique [0002] A key element in the analysis of the scientific literature is to analyze what research questions a field has and what are the main methods currently available to address them. With the rapid development of the times and the continuous improvement of scientific research capabilities, the total number of scientific literature is also growing rapidly. Therefore, there is an increasing need for a technology that can extract problem and method pairs from a large number of scientific literature, so as to further analyze the development trend of science and technology and help Optimize the allocation of research resources. [0003] As an important part of scientific literature, papers have the characteristics of high timeliness, large volume, and fast growth. The...
