Concerning the issues of Web text with little structure information and big noise, sentences are viewed as nodes and similarities between them are viewed as edges, a relationship map is used to describe the relationship between sentences. Topic sentences of a text can be got through searching the nodes which have most of edges. Using the semantic dictionary, sentence similarity is defined as its semantic similarity to address the problem of low word frequency similarity of short text. An internet public campus is chosen to take a test, 80.6% acceptability have been achieved.
