The Design And Realization Of Tourism Information Vertical Search Engine Based On Travel Notes

Nowadays people's living standards has been improved steadily. More and more people begin to pay attention to the spiritual ascension. Tourism has become an important means of people daily leisure and relax. It is essential to make up your lessons before traveling. Sites selection, route planning, characteristic food, local customs, all of these are topics of concern to each tourist. It often takes a lot of time and effort of tourists to select and work out a travel plan in the vast network. As people's play summary, travel notes not only recorded travelers' prevailing mood, but also contains important travel information, including attractions profiles, personal feelings, the play line, the cost and so on. In order to reduce the preparation time before the trip, this paper will design and implement a vertical search engine system based on travel notes. The system can recommend travel routes and wonderful travels for tourists.The main works of this paper are as follows:1) The key technology of vertical search engine is studied.First, this paper briefly introduces the background of tourism demand and the development of search engine, and explains the differences between different search engines according to the collection and service mode. Next, the key technology of vertical search engine is studied, including the working principle of the crawler, topical crawler algorithm, Chinese word segmentation algorithm and inverted index. Then, introduces Lucene's using method, function structure, indexing and retrieval strategy, scoring mechanism in detail.2) Design and implement a tourism information vertical search engine system based on travel notes.The system mainly consists of three modules: information collection module, index module, and query module. The information collection module extractes travel information from the web page which is processed into a structured information and stored in the local disk by the WebMagic crawler framework. The index module uses the full text search tool kit Lucene to index the structured information which is stored in the local disk. The query module includes retrieval function and page displaying function, and the retrieval function scores the document based on the users' queries and returns the results to users by using Lucene's serch strategy, and the page displaying function displays the query results by using SpringMVC framework.According to the actual situation of the tourists' travel and the survey of tourists' travel requirement, this paper designs and implements a tourism information vertical search engine system based on travel notes.
