负关系 meaning in English

negative relationship

The negative relation plays the same role with the positive relation from the view of the mathematics and formal logic
从数学、形式逻辑等学科技术中也容易看出，负关系所起的作用与正关系一样重要。
Communities of a signed network are defined as the groups of vertices , within which positive relations are dense and between which negative relations are also dense
符号网络中的共体是指多个不相交的节点集合，集合内的正关系稠密而集合间负关系稠密。
So the problem of mining communities of signed networks quickly and correctly has not been solved satisfactorily . in this paper , we propose a heuristic algorithm to address this issue
值得注意的是，当前有关万维网挖掘的工作都是基于只包含正关系的web图模型，而忽略了负关系的存在，如公司之间的竞争关系。
