Embodiment 1

[0051] This embodiment provides a method for automatically evaluating the novelty of scientific and technological documents using a computer, which includes the following steps:

[0052] A. Novelty detection based on document content ranking;

[0053] B. Novelty detection based on document semantic comparison;

[0054] C. Novelty detection based on key terms;

[0055] D. Novelty detection based on numerical indicators;

[0056] E. Obtain their respective novelty scores based on steps A-D, and use the regression model to calculate the total novelty score of the newness search document.

[0057] Such asfigure 1 As shown, in step A, when the user input content is searched and compared, a search and sorting method based on content relevance is adopted to retrieve the text most relevant to the user input content from the library. The task of similar text retrieval is to find a document that is most similar to it in a document library given a piece of text, and sort the documents...

Embodiment 2

[0095] This embodiment provides another method for automatically evaluating the novelty of scientific and technological documents, such as Figure 4 As shown, the method of the present embodiment includes the following steps:

[0096] Step 1: Compare the novelty search documents with domestic or foreign documents respectively, and get the scores of domestic and foreign indicators. Each indicator score includes: relevance based on content ranking, similarity based on semantic comparison, key term score, and numerical indicator score.

[0097] Step 2: Then use the regression model to calculate the total score of domestic and foreign novelty of the new document. The regression model used in this study is multiple linear regression, whose independent variables are often affected by several important factors, and two or more influencing factors need to be used as independent variables to explain the changes of the dependent variable. The novelty evaluation system involves multipl...

Abstract

The invention provides a method for automatically evaluating scientific and technical literature novelty by utilizing a computer. The method comprises the following steps: A, detecting the novelty on the basis of document content ranking; B, detecting the novelty on the basis of document semantic comparison; C, detecting the novelty on the basis of key terms; E, detecting the novelty on the basis of numerical indexes; and E, respectively obtaining the novelty scores on the basis of the steps A to D, and calculating the total novelty score of the novelty search document by utilizing a regression model. By adopting the method provided by the invention, the automatic novelty search of scientific and technical literatures can be carried out on the basis of multi-dimensional novelty detection, so that the scientific and technical novelty search efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of scientific and technological search technology, and in particular relates to a method for automatically evaluating the novelty of scientific and technological documents by using a computer. Background technique [0002] With the construction of my country's national innovation system and the implementation of independent innovation capacity planning, the country has vigorously promoted technological innovation in various major fields. The number of scientific and technological projects approved and the number of awards for major scientific research achievements in my country are increasing rapidly. In the process of scientific and technological innovation, how to accurately choose the direction of scientific research, correctly establish projects, avoid repeated project approval and ineffective scientific research investment, and avoid detours. , are key issues that scientific research institutions urgently need to...
