Package parse

source code

Classes and interfaces for producing tree structures that represent the internal organization of a text. This task is known as parsing the text, and the resulting tree structures are called the text's parses. Typically, the text is a single sentence, and the tree structure represents the syntactic structure of the sentence. However, parsers can also be used in other domains. For example, parsers can be used to derive the morphological structure of the morphemes that make up a word, or to derive the discourse structure for a set of utterances.

Sometimes, a single piece of text can be represented by more than one tree structure. Texts represented by more than one tree structure are called ambiguous texts. Note that there are actually two ways in which a text can be ambiguous:

However, the parser module does not distinguish these two types of ambiguity.

The parser module defines ParseI, a standard interface for parsing texts; and two simple implementations of that interface, ShiftReduce and RecursiveDescent. It also contains three sub-modules for specialized kinds of parsing:
