ABSTRACT
Beyond the literal information extracted from text with lexical analysis and syntactic analysis, the pragmatic information has begun to be processed by machines today. Advanced human language technologies attract the attentions of researchers and generate practical applications. For example, opinion mining is a hot topic in the natural language processing (NLP) community and can be applied to various tasks such as opinion summarization and opinion tracking. Computational discourse analysis is another higher-level NLP, which deals with the information from the related and meaningful sentences (Mitkov, 2010).
