The target of dada mining is to extract the potential, valuable pattern or regulation in the data from a great quantity. With the fast development of computer net, the large of data of teaching evaluation is accumulated. The analysis and processing technology to evaluation data is worse than data acquisition technology, which does not satisfy the demand of(More)
Filter the original data by using the itemsets that the users are interested in. At the time of producing the frequent itemsets, filter the data again according to the frequent data itemsets of large one itemsets (L<inf>1</inf>) and large two itemsets (L<inf>2</inf>). This can reduce the data in the database. At the time of producing the rule, making use of(More)
In the course of the workflow implementation, it is important that tasks are implemented smoothly, efficiently, and tasks are distributed equilibrium in the depth and breadth. The paper puts forward a kind of shortest path selection algorithm based on power directed diagram, which makes the workflow implementation be converted into directed diagram shortest(More)
