Tourism Opportunity Recognition Based On Digital Footprint Research On The Construction Of Spatio-temporal Map Of Tourism Opportunities

Although the application of big data in the tourism industry has been widely valued,the construction of tourism opportunity big data as the basic data for the development of tourism industry has been slow in construction.Although there have been efforts to build cross-regional tourism resource census data in recent years,these data still suffer from costly and slow updates.The spatio-temporal mapping of tourism opportunities proposed in this paper can solve the above problems.The "tourism opportunity spatio-temporal mapping" is a database that records the spatio-temporal distribution information of tourism opportunities in the whole region,which has the characteristics of spatial multi-scale,temporal multi-grain size and classification multi-dimension.More importantly,tourism opportunity spatio-temporal mapping can achieve tourism opportunity identification and data update by mining tourism digital footprints,thus realizing the low-cost and rapid update of tourism opportunity big data.Tourism opportunity mining based on tourism digital footprint must solve the problem of semantic recognition and key content collection of tourism digital footprint.In this paper,a method of intelligent mining of tourism opportunities based on semantic recognition is implemented by using natural language processing technology.The method can automatically identify tourism opportunity types,tourism opportunity contents,time and location for the collected digital footprint contents such as microblogs,We Chat public numbers,news and comments,so as to realize large-scale and fast identification and library building of tourism opportunities based on digital footprints.Meanwhile,this paper selects Jiulongpo District of Chongqing City as a case study to investigate the effect of constructing tourism opportunity spatio-temporal mapping based on digital footprint and explore the application of tourism opportunity spatio-temporal mapping.In this paper,three typical types of tourism opportunities,namely urban tourism,rural tourism and nostalgic tourism,are selected,and the spatio-temporal mapping of tourism opportunities in Jiulongpo District for four seasons,namely spring,summer,autumn and winter,is constructed and visually expressed in ArcGIS.The study shows that the construction method of tourism opportunity spatio-temporal mapping based on digital footprint constructed in this paper is feasible,and the mining and application of tourism opportunity spatio-temporal mapping through Jiulongpo also proves that tourism opportunity spatio-temporal mapping has a wide application prospect.
