Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the traditional book recommendation algorithm adopts the method of collaborative filtering, which inevitably encounters the cold start problem of recommendation. At the same time, this method can only ignore the popularity of books based on content relevance. Correlation

Abstract

The invention belongs to the technical field of information retrieval and database structures, and discloses a book heat degree correlation detection method based on publishing time and a forgetting curve. The book heat degree correlation detection method based on publishing time and a forgetting curve comprises the following steps: calculating objective heat degree correlation; the forgetting curve calculating the subjective heat; combining subjective heat and objective heat to calculate the correlation of book heat. The method can calculate the heat degree correlation of a book based on thepublishing time, and can alleviate the cold start problem of the book recommendation and improve the performance of the recommendation by combining the collaborative filtering algorithm.

Description

technical field [0001] The invention belongs to the technical field of information retrieval and its database structure, and in particular relates to a method for detecting the correlation degree of book popularity based on publication time and forgetting curve. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: the emergence of the Internet and search engines can quickly obtain information at home and abroad. However, with the increasing number of netizens and the influx of online information, people often feel that they have no way to start. Massive information bombardment cannot quickly select information that is useful and interesting to oneself. For those search engines, how to quickly provide users with effective information and improve competitiveness is particularly important. The recommendation system came into being and is widely used in social networking sites, music sites, film and television sites ...
