酒店訂購平臺搜索系統(tǒng)的設(shè)計與實現(xiàn)
[Abstract]:With the progress of society and the improvement of people's demand for material and culture, tourism, as a new industry in the tertiary industry, has been developed rapidly. In recent years, with the development of mobile internet, more and more enterprises are involved in tourism electronic commerce, which provides more convenient service for customers. At the same time, the vigorous development of tourism has led to the hotel industry, China's hotel industry scale multiple accelerated development. The combination of computer network and hotel industry has brought new vitality to hotel industry, and hotel network ordering has become a new consumption mode for hotel users. However, there are still many problems in the e-commerce mode of hotel online ordering. In the virtual environment, hotel merchants provide a large number of hotel information and complex, so that consumers dizzying. In order to enable hotel users to select their own content from the massive data, it is an inevitable trend to develop a search system with exclusive hotel ordering platform. Hotel order platform search system is divided into two parts: hotel search online service and hotel offline search service. In the design and development of hotel search online service, the author has completed the following work: (1) the design, development and functional testing of hot word service module have been completed independently. Hot word service provides hotel users with hotel-related hot words and gives them guidance when they can not choose or lack goals, thereby increasing the purchase rate of the users. The hot word service module is developed by Thrift framework and only provides the client service interface, which greatly facilitates the user to invoke the hot word service. In order to ensure the accuracy and real time of hot words service, log information is used as the etymology of hot words after the associated users search the records, and the ETL files are regularly updated and written to MySql database as hot word candidates. In order to meet the needs of hotel users to the greatest extent, hot word service provides a variety of hot words and shows hot words in different destinations according to the user's choice. (2) the design of intelligent prompt service module is completed independently. Development and functional testing. The intelligent prompt service module has two different applications in the search system. It is divided into two parts: destination switch submodule and keyword search prompt module. The two submodules are independent service modules and developed with Thrift framework. Intelligent prompt service module realizes prefix word matching based on Trie tree and fuzzy matching function by redundant storage. The service supports four input modes: pure Chinese character, pure pinyin, simple spelling and pinyin, and returns the corresponding Chinese character recommendation results. Considering the semantic diversity, the intelligent prompt service extends the synonym of etymology according to the rules and realizes the function of intelligent error correction. In order to enable users to compare their input content and recommendation results intuitively, the corresponding parts of the recommended results are highlighted. (3) the design of the basic retrieval module and the development of some sub-functions are completed. In order to ensure the efficiency of index building, the full-text retrieval technology based on Sphinx engine is adopted. In order to ensure the accuracy of retrieval, the query syntax tree is built with finite state mechanism, and the optimization part of query syntax tree is added to improve the performance. The method based on geographical position weight and TF-IDF is used to sort the retrieval results. At present, the hotel order platform search system has entered the online service state, the author is responsible for the design and development of each module is running normally, on the basis of meeting business requirements, each module has good scalability, Easy to follow up maintenance work.
