[Purpose/Significance] To generate high-quality cultural resource tags for scenic spots, and solve the problems of difficult information retrieval and signal recommendation form in cultural tourism services.[Method/Process] First, a tag system for cultural resources including explicit and implicit tag types was designed; then, an explicit tag generation method based on feature word filtering and noise word filtering was proposed, and the calculation method of cultural perception intensity and cultural perception similarity in implicit tags was designed, and cultural resource tags of scenic spots were generated based on the above methods; finally, for different scenarios in tourism information services, retrieval methods and recommendation methods based on cultural resource tags were provided.[Result/Conclusion] Taking the real tourism data of Wuhan as an example to conduct empirical research. The results show that the tags generated based on this method can accurately describe the cultural resource characteristics of scenic spots, and the retrieval and recommendation algorithms based on tags have strong interpretability, which can effectively improve the transparency of information services and users' trust in the results, and have reference value for recommendation and interpretation research in other fields.
