There are three steps here. The first step is to generate the SegGraph, the second step is to create the BiSegGraph, and the third step is to find the shortest path as the result. For the two figures here, refer to the related sections in the ICTCLAS algorithm introduction. Generally, the first graph is all possible words, and the second graph is the possible combination between words (path of directed graph ). The nodes in both charts have the weight attribute.
