Abstract

The invention relates to an information recommendation system based on big data. The system comprises a data acquisition module, a data partitioning module, a data mining analysis module, a data storage module, an information recommendation module, a terminal module and a cloud module, the data mining analysis module adopts an effective mechanism to effectively process a large amount of data and solve the sparsity problem, the defects of a single algorithm are eliminated, and the recommendation effect is improved. In the aspect of system architecture, user opinion rating and project rating areintegrated, and a reliable recommendation result can be obtained.

Description

technical field [0001] The invention relates to the technical field of big data, in particular to an information recommendation system based on big data. Background technique [0002] In recent years, big data, as a tool that can be obtained within acceptable computing time and whose data volume exceeds traditional data, has become an information asset that many companies, scientific communities, and governments pay more and more attention to. The existing challenge is how to extract relevant and needed information for a specific purpose by exploring and analyzing data. [0003] Due to the explosive growth of information available on the web, users are faced with the key challenge of a large number of choices. This is the problem of information overload. It is very difficult for users to find accurate information. This problem also expands the user's demand for effective information screening technology. , they hope that technology can help them find the right content accor...
