Research Progress and Hotspot of Information Retrieval Correlation based on CiteSpace

Taking 1760 journal papers of information retrieval relevance in the core database Web Science as research object, using literature co-citation network and keyword co-occurrence analysis, with visualization means, this paper summarizes on retrieval. It is found that current correlation concentrated, which mainly divided into two main knowledge groups, algorithm cognition, few frontier branches. And fusion between groups needs to be strengthened. Since emergence natural language processing, has been improved along path processing-machine learning-deep learning.
