Method for analyzing implicit type discourse relation based on hierarchical depth semantics

The invention relates to a method for analyzing implicit type discourse relation based on hierarchical depth semantics, and belongs to the technical field of application of natural language processing. The method comprises the following steps of firstly, combining marked and unmarked corpuses, expanding the corpus training scale, and solving the problem of under-learning due to undersize corpus training scale; then, according to a certain rule, initializing a depth semantic vector of each corpus training hierarchy, sorting word pairs favorable for classification according to information gain value, and using the word pairs as subsequent feature selection basis; finally, designing a scoring function, combining the multiple hierarchial depth semantic information of to-be-classified discourse relation theory element pairs, utilizing the parameters of a nerve network training model, fitting a type tag of the implicit type discourse relation, and finding the model for furthest optimizing the performance, so as to complete the analysis of the implicit type discourse relation. The method has the advantages that the false judging of the traditional method based on discrete features is overcome; the analysis accuracy of the type tag of the implicit type discourse relation is improved; a user can quickly and accurately obtain the analysis result of the implicit type discourse relation.

Method and system for identifying Chinese event sequential relationship

The invention provides a method and system for identifying a Chinese event sequential relationship. Each document of an original text, the event sequential relationship of which needs to identify, is subjected to word segmentation, entity identification, syntactic analysis, dependence relationship analysis and event extraction action, such that a test corpus event set is obtained; all event pairs and feature information thereof are respectively extracted from the test corpus event set and a labelled corpus set; a maximum entropy event sequential relationship identifying model is trained according to the features of various event pairs in a labelled corpus feature set; the sequential relationship of each event pair in the test corpus feature set is identified by utilizing the maximum entropy event sequential relationship identifying model, such that a first event sequential relationship set is obtained; and, by taking the document as the unit, event sequential relationship reasoning of all the event pairs in the first event sequential relationship set is carried out by utilizing a word denoting time reasoning method, an event relationship reasoning method, a reflexive reasoning method and a transitive reasoning method, such that an event sequential relationship set is obtained.
