RESEARCH ON PERSONALISED SERVICE PUSH MODEL FOR AGRICULTURAL SCIENCE AND TECHNOLOGY INFORMATION
摘要
Abstract
To solve the problems of low sharing rate and scattered distribution the agricultural science and technology information has,we use web information extraction method to realise the automatic acquisition and warehousing of multi-source agricultural information,and employ XML file to achieve failures retry mechanism.By processing web log files and using improved k-means clustering method to establish user accessing pattern,we obtain the set of webpages feature words and its weight of the accessing pattern and construct the library of user interest models to push the webpage for visiting session.In practical application,the user models library is updated timely so as to guarantee the timeliness of web contents and the reliability and availability of push service.关键词
