Random walk model-based zero-reference article recommendation method and system

Abstract

The invention provides a random walk model-based zero-reference article recommendation method and system. The method comprises the following steps of 1, constructing an academic network model, and obtaining feature values corresponding to a first author, a conference or periodical, a mechanism and a published time of each paper through a random walk method; 2, establishing a sorting model, and selecting paper data processed in the step 1 to construct a training set; 3, sorting the training set through a weak classifier; 4, judging whether the sorting result of the weak classifier is matched with a real sorting result of the training set or not, so as to obtain an optimal sorting model; and 5, recommending zero-reference literatures required by the users through the sorting model. According to the method and system provided by the invention, a brand new paper sorting through is used, so that the newly published papers can be recommended more effectively and then the users can obtain the most relevant new papers.

Description

technical field [0001] The present invention relates to the technical field of recommendation, in particular to a zero-citation article recommendation method and system based on a random walk model. Background technique [0002] Scientific research activities are the strategic support for improving social productivity and comprehensive national strength. All countries in the world attach great importance to investment in scientific research activities. my country has put scientific and technological research and development at the core of the overall national development, and the national financial expenditure on scientific research has steadily increased. In 2012, China's research and experimental development investment (including industry and academia) has exceeded one trillion yuan, reaching 1029.84 billion yuan, reaching the level of moderately developed countries. [0003] One of the most direct outputs of scientific research activities is academic papers. According ...

Problems solved by technology

However, ranking research in the face of newly published papers is still in its infancy

Tens of thousands of new papers are published every year. The lack of accurate sorting algorithms in this field makes it impossible for researchers to quickly find the information that meets their needs from the massive data
