A Coherence Analysis Model for English Essay Based on Sentence Semantic Graph

Sentence similarity measures for essay coherence

This paper describes the use of different methods for semantic similarity calculation for predicting a specific type of textual coherence. We show that Random Indexing can be used to locate documents in a semantic space as well as terms, but not by straightforwardly summing term vectors. Using a mathematical translation of the semantic space, we are able to use Random Indexing to assess textual...

But both argumentation semantics and crosssentence syntax (such as corefe...
