| Abstract: | Through the analysis of the input text,the discourse structure of the text is partitioned,and the text is represented by a text structure tree,which has five levels of text title,text chapter,paragraph,complex sentence and clause that have an inclusive relation with each other.A tagging method is presented,and the automatic indexing of discourse structure is discussed and implemented.Two indexing algorithms are presented,and the results of the comparison between the two algorithms are given.It shows that th... |
