Abstract: Objective This paper reviews the relevant progress of semantic novelty research at home and abroad, and summarizes the relevant technologies to provide reference for the subsequent research. Coverage Using retrieval methods such as Novelty of the literature , semantic novelty , literature novelty , semantic novelty and literature evaluation , after reading and sorting, this paper traced the source of representative relevant theoretical researches, and finally selected 70 literatures for review. Methods This paper summarizes the relevant researches on semantic novelty at home and abroad, and analyzes the development status and future trend of semantic novelty evaluation in scientific and technological literature by focusing on the definition of novelty, evaluation indexes of novelty and different evaluation methods. Results Semantic novelty evaluation has gradually attracted widespread attention from the academic community. There have been related studies on semantic content mining and evaluation, but no unified measurement index has yet been formed. Limitations The existing literature novelty is mostly evaluated from external features, while the number of literatures directly focusing on semantic novelty is small, which has limitations in supporting the review. Conclusions The evaluation of semantic novelty of scientific and technological literature is based on the novelty of content. Quantitative research has become the mainstream research method, but the calculation method of evaluation index needs to be clarified, and the development direction of novelty evaluation should be combined with qualitative and quantitative methods to achieve a scientific and reasonable comprehensive evaluation.
