Analyzing Sentence Structure

چکیده
Earlier chapters focused on words: how to identify them, analyze their structure, assign them to lexical categories, and access their meanings. We have also seen how to identify patterns in word sequences or n-grams. However, these methods only scratch the surface of the complex constraints that govern sentences. We need a way to deal with the ambiguity that natural language is famous for. We also need to be able to cope with the fact that there are an unlimited number of possible sentences, and we can only write finite programs to analyze their structures and discover their meanings.

Analyzing Syntactic Structure
For analyzing the structure of a sentence we will use constituent analysis, a hierarchical model introduced by Chomsky [1]. In this framework, sentences are modeled in the form of a parse tree (see Figure 1), where leaves are lexical items, or terminals, and internal nodes are constituent labels. The constituent labels form grammatical types from the lexical items, and lexical items form the se...

متن کاملInvited Talk: A Note on the relationship of discourse structure to information structure
Although it is generally accepted that a sentences information structure (IS) is determined by its relationship to previous text, the question of how to establish the appropriate discourse context for IS assignment is never raised. Analyses of IS normally assume that that sentence is a question and the target sentence is the answer to that question [1]. The assumption is always that the prior c...
