Associated data, which refer to sets of entities with specific relations and relational weights that can usually be expressed in a relational matrix, are found in many fields.Two typical examples are the pesticide residue dataset in food-safety, in which pesticides are associated with agricultural products [1], and E-transaction dataset, in which there is special relation between buyer and seller [2].However, on large data scales, finding the key entities or mine hidden patterns in such data is difficult and time consuming.An ordered matrix can help analysts quickly locate the entity of interest.
