Abstract:

Information accessibility construction is a social welfare service for vulnerable groups to obtain information equally. We will use the Apriori algorithm in Web log data to find the mining association rules to guide the design and to develop the information accessibility website. The Apriori algorithm was used on the information of the web page URL access frequency accessed by a large number of users to get the association rules.According to the 3-click principle and design of website structure, only all 3 frequent item sets should be find out based on the Apriori algorithm, the algorithm improvement reduces the time complexity of Apriori. Through the analysis of the association rule to get the type of webpage which most users interested in, we find the link relations of browsed pages.

Key words: information accessibility, Apriori algorithm, data mining, association rules
