Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of document analysis, and particularly relates to a document influence index analysis method. BACKGROUND

[0002] In recent years, the research achievements in various fields are fruitful, and the number of published documents continues to grow. Therefore, it is very important to efficiently determine the most instructive documents for current research from a large amount of documents. At present, bibliometrics is a widely used method in academic competitiveness evaluation to help researchers efficiently mine the frontiers and hotspots in the concerned field.

[0003] In the prior art, when a researcher determines the influence of a document, only the burst strength of the document is considered to determine the frontiers and importance of the document. The burst strength is calculated by the number of citations of the document. When the number of citations of the document is large, the value of the burst strength is large. When the number of citations of the document is small, the value of the burst strength is small.

[0004] However, only the number of citations of the document is considered when determining the burst strength. Therefore, the accuracy of the determined burst strength is low and is relatively one-sided. Moreover, only the burst strength of the document is considered when determining the frontiers and importance of the document, and the elements of the document are not comprehensively considered. Therefore, the determination of the frontiers and importance of the document by the researcher is affected, and the frontiers and importance of the document cannot be accurately and comprehensively determined.

[0045] T is a time interval between the current year Y and the year Y of the end of the burst. n T is a time interval between the current year Y and the year Y of the end of the burst. n T = Y-Y n3 n n3 .

[0046] Thus, in the present application, the burst strength of the literature is calculated by the burst state of the literature, the proportion of the burst literature, which is more accurate, reliable and reasonable than the burst strength of the literature determined by the cited amount of the literature in the prior art, and avoids the one-sidedness of the burst strength caused by the cited amount of the literature.

[0047] In the judgment of the frontiers and importance of the literature, the various factors of the literature are comprehensively considered, that is, the current year, the burst strength, the literature sequence, the publication year, the year of the beginning of the burst, the year of the end of the burst, the burst duration, the time interval between the current year and the year of the end of the burst, that is, the frontiers and importance of the literature are comprehensively analyzed from various factors, which is more accurate and comprehensive than the frontiers and importance of the literature determined by only the burst strength in the prior art.

[0050] ​​​Web of Science database is an important database platform for obtaining global academic information. Web of Science has three citation index systems (SCIE+SSCI+A&HCI) which include more than 12400 kinds of international academic journals with high authority and high impact in the world, covering natural science, engineering technology, social science, art and humanities and other disciplines.

[0051] Therefore, based on the Web of Science database, the required literature can be more comprehensively and quickly screened, and the cited quantity, publication year Y n1 and the current year Y of the literature can be accurately obtained.
