Digital content resource value evaluation method based on GCA-RFR model

Abstract

The invention discloses a digital content resource value evaluation method based on grey correlation analysis and a random forest regression GCA-RFR model, and the method comprises the steps: taking avalue chain theory as a main line to explore an influence factor of a content resource value, and constructing a content resource value evaluation index system according to the influence factor; crawling related data of an Internet movie database by means of Python, and cleaning the data by deleting and replacing the data cells to obtain valid data; performing index verification and screening byusing a generalized grey correlation analysis method to obtain a final effective index system; carrying out initial sample screening based on an entropy-Dane grey correlation analysis method, and obtaining a final sample set for model training; and based on the index system and the training data, continuously optimizing a random forest regression RFR model to construct a digital content resource value evaluation method. According to the invention, a digital content resource value evaluation function is realized, and the method has high scientificity, effectiveness and wide applicability.

Description

technical field [0001] The invention belongs to the field of standardized content resource transactions, and relates to a digital content resource value evaluation method based on gray relational analysis and random forest regression model (GCA-RFR). Background technique [0002] According to the "2017-2018 Annual Report on China's Digital Publishing Industry", the digital publishing industry has surpassed "traffic is king" and reached a new era of "content is king", and content production is gradually becoming more specialized and high-quality. With the establishment of 10 national standards such as "Data Processing of Content Resources", digital content publishing will become increasingly standardized. In addition, the operation ecology of Internet literature IP (IntellectualProperty) is gradually mature. On the basis of paper books, it is not uncommon to develop diversified content IP development models such as movies, TV dramas, animations, and games. However, as an eme...

Problems solved by technology

[0003] At present, there are mainly the following problems in the transaction of content resources in my country: ①The quality of digital content resources is uneven, and there is no clear publishing standard; ②Most of them are bundled with other services (such as advertisements, memberships, etc.) There are many factors involved in the full life cycle of resources, and some subjective factors are difficult to measure; ④The core elements of digital content resources—the definition of content copyright and its value evaluation have no uniform standards
