After making word segmentation on some results which are returned from component search engine and extracting the main keywords,then it uses association rules to build up an associated word matrix,and adopts the FCM(Fuzzy C-Means) algorithm to make fuzzy clustering for the results based on the matrix.

Distribution network flow calculation basedon incidence matrix squaring;

A method to establish OOPN incidence matrix for net performance analysis;

Consumable gas of compressor stations was not taken into consideration when branched gas pipeline networks flow equations were described with the incidence matrix method in the past,which would result in unavoidable deviation.

Then, the reengineering algo- rithm of incident matrix was employed to describe all the activities.

On this basis,it discusses,by using determinant,the calculation method of the number of tree graph vertices of the known connecting graph according to the nature of the basic incident matrix.

Furthermore, an incident matrix_based reengineering algorithm is proposed and used to describe the activity patterns determined.

In the paper an algorithm in building weighted directed graph is developed, the graph s weighted directed relationship matrix is defined, and how to implement the algorithm with the relationship matrix in computation is illuminated.

In the paper, the concept of system relationship matrix is presented, subsequently, a new diagnosis method based on relationship matrix is given.

An algorithm for mining frequent subgraphs based on associated matrix was proposed.

After all these preparation work,can get the associated matrix which is also the input of the improved fuzzy c-.

In the definition of associated matrix between elements,the level of knowledge.

Based on the concept of discernibility matrix,a new concept called association matrix is proposed in this paper,and an attribute reduction algorithm is given accordingly.

Then an association matrix between the estimate locations and foreground blobs is built to distinguish many different situations that possibly occur in .

The revised algorithm construct an association matrix and an association graph at the same time and in the phase of generating candidate itemsets the Apriori property based on association graph is utilized to prune the redundancy,thus the number of candidates is cut down and the validation of candidates is simple.
