The probability distribution over possible worlds x specified by the ground Markov Network M L,C is given by where n i (x) is the number of true groundings of F i in x, x {i} is the true value of the atoms appearing in F i , and In the case of Chinese NER, a named entity can be connected to another named entity for instance, because they share the same location salient word.
in an undirected graph, two node types exist, the LOC nodes and the location salient word nodes.
