释义 | BETA Examples of parserparser isn’t in the Cambridge Dictionary yet. You can help! An experimental comparison of deductive and inductive feedback generated by a simple parser. How does the parser deal with input that is compatible with more than one grammatical analysis though? For the parser to be able to make any structurally based attachment decisions, sufficiently detailed, hierarchical representations must be available in the first place. The next major development will be the interface between the parser and the lexical database. The argument is that children must begin the acquisition process with adult-like parsers because otherwise they could not make use of the input. The efficiency of a parser combinator library usually revolves around a good implementation of the choice operator, which indicates a non-deterministic choice in the grammar. In general, fourth-order combinators may both take and return third-order parsers. The convention is that the empty list of results denotes failure of a parser, and that non-empty lists denote success. A more interesting example of bind uses a predicate to filter the results of a parser. Like the parser this also serves as a good debugging aid by allowing the student to view the output of any pass in host-language form. The turn-around is a measure of how long it takes to create a usable parser from a program script of grammar file. In this more refined approach of his rhetorical parser, he proposes to combine different heuristics in order to decide on the best discourse tree. Robust parsers are also based on the notion of under-specification. Current robust discourse parsers, however, face the following three problems. Now robustness can be assessed by the simple observation that: it is proportional to a given parser performance index. The resulting path was then used as input for the parser. The shallow parser is then applied to the corpus. While using supervised machine learning to train discourse parsers looks promising, annotating texts with their discourse structure is time-consuming. |
