Abstract: As the refinement of the content of the thesis, the paper has the characteristics of generality, importance and obvious features. The analysis of keywords can eliminate the redundant information of the paper content, grasp the essence and improve efficiency. This paper takes the key words of IFLA Conference Papers in 2014-2018 as the research object, and designs the keyword semantic indexing model of academic papers based on digital library. The keywords are based on research background, research field, research hotspots and research objects. This paper marks the key words of the papers collected by the IFLA conference in the past five years, constructs an annotated data set, and analyzes the keywords of different semantic functions to reveal the IFLA research hotspots and research trends in the field of libraries.

Key words: digital library, semantic indexing, technical application
