Learning Materials are structured as Learning Objects and are available in Learning Object Repository(LOR) which are used in various courses of an Elearning environment. Learning Management System aggregates these objects found in LOR, provides an infrastructure and platform through which learning content is delivered and managed. Adaptation, personalization, usage statistics are some of the LMS functionality...
As the databases grow in size, the interpretation of data within them, is increasingly difficult to obtain, and often only stored as backup of various transactions of records. In this data there is new information which is present, but requires a higher level of processing. This will create the association rules which are used to detect events that occur together in a set of data. To find these rules,...
This paper introduces an algorithm of mining spatial topology association rules based on Apriori, which is used to mining spatial multilayer transverse association rules from spatial database. This algorithm creates candidate frequent topological itemsets via down-top search strategy as Apriori, which is suitable for mining short spatial topological frequent itemsets. This algorithm compresses a kind...
A novel adaptive method included two phases for discovering maximal frequent itemsets is proposed. A flexible hybrid search method is given, which exploits key advantages of both the top-down strategy and the bottomup strategy. Information gathered in the bottom-up can be used to prune in the other top-down direction. Some efficient decomposition and pruning strategies are implied, which can reduce...
