Embodiment 1

[0038] Such as figure 1 As shown, Embodiment 1 of the present invention provides a method for establishing a classification model applicable to link resource citations in scientific and technological documents, the method comprising:

[0039] Step S1) Constructing a resource reference data set by using an existing document data set; the data set includes resource hyperlinks and related resource description texts;

[0040] Resource citation: the hyperlink mentioned by the author in the text, which directly points to a specific online resource; resource description text: the continuous text that the author appears near the resource citation, especially the text that appears before and after the hyperlink. Extract the hyperlinks of the resources from the text and footnotes of the literature, and extract the five sentences before and after the hyperlinks as the description text of the resources;

[0041] Step S2) labeling the training data set based on the knowledge repr...

Embodiment 2

[0083] Based on the knowledge representation framework and classification model established by the above method, the present invention also provides a method for classifying link resources in scientific and technological documents, the method comprising:

[0084] Step T1) extracting the description text of the resources to be classified;

[0085] Extract the hyperlinks of the resources from the text and footnotes of the literature of the resources to be classified, and extract the five sentences before and after the hyperlinks as the description text of the resources. After extracting the description text of the resource to be classified, it also includes: adding a reference position identifier in the description text, that is, inserting at the position where the reference appears in the text Marker, added to the text as an independent word, is used to indicate that a resource reference occurs at the current position.

[0086] Step T2) Input the description text into ...

Embodiment 3

[0089] A computer device includes a memory, a processor, and a computer program stored on the memory and operable on the processor, and the method of Embodiment 2 is implemented when the processor executes the computer program.

Abstract

The invention discloses a method and system for classifying link resources in scientific and technical literature, equipment and a storage medium. The method comprises the following steps of: extracting a description text of resources to be classified; and inputting the description text into a pre-trained classification model to obtain a classification result based on a knowledge representation framework, thereby realizing classification of the to-be-classified resources. According to the method, the recognition model is constructed through the neural network method based on context information according to the semantic characteristics of the link resources in the scientific and technical literature, recognition of the resources can be effectively improved, and management, analysis and recommendation of the scientific and technical link resources are facilitated.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to the field of retrieval, management and evaluation of link resources in scientific and technological documents, and in particular to a method, system and equipment for classifying link resources in scientific and technological documents. Background technique [0002] With the rapid development of science and technology, a large number of scientific and technological literature has been published, and at the same time, a large number of online resources have been published or used. Therefore, tracking and modeling for scientific and technological resources such as software tools and databases becomes particularly important and challenging. Google released a search engine in 2017 to help scientists search for the datasets they need. However, this search engine can search the corresponding database only with the accurate name. [0003] Aiming at the method research of...
