Ambiguity Management in Grammar Writing
نویسندگان
چکیده
When lingusitically motivated grammars are implemented on a larger scale, and applied to real-life corpora, keeping track of ambiguity sources becomes a difficult task. Yet it is of great importance, since unintended ambiguities arising from underrestricted rules or interactions have to be distinguished from linguistically warranted ambiguities. In this paper we report on various tools in the XLE grammar development platform which can be used for ambiguity management in grammar writing. In particular, we look at packed representations of ambiguities that allow the grammar writer to view sorted descriptions of ambiguity sources. Also discussed are tools for specifying desired tree structures and for cutting down the solution space prior to parsing.

متن کاملEnriching text with tone marks: An application to Kinyarwanda language
The absence of tone marks in text can be considered an instance of defective writing. Yet most writing systems of tone languages in Africa do not mark tone. This adds to ambiguity, which must be resolved on the basis of the context. Using tone-marked lexicons and tone rules the ambiguity can be resolved. This paper deals with a further problem, i.e. how to insert tone marks into a text without ...
