TDL--- A Type Description Language for Constraint-Based Grammars
نویسندگان
چکیده
This paper presents TDL, a typed feature-based representation language and inference system. Type deeni-tions in TDL consist of type and feature constraints over the boolean connectives. TDL supports open-and closed-world reasoning over types and allows for partitions and incompatible types. Working with partially as well as with fully expanded types is possible. EEcient reasoning in TDL is accomplished through specialized modules.mar formalism for typed feature structures.

متن کاملClassiication and Representation of Types in Tdl
This paper presents TDL, a typed feature-based representation language and inference system, speciically designed to support highly lexicalized constraint-based grammar theories. Type deenitions in TDL consist of type and feature constraints over the full Boolean con-nectives together with coreferences, thus making TDL Turing-complete. TDL provides open-and closed-world reasoning over types. Wo...
متن کاملTDL: A Hardware Description Language for Retargetable Postpass Optimizations and Analyses
The hardware description language Tdl has been designed with the goal to generate machine-dependent postpass optimizers and analyzers from a concise specification of the target processor. Tdl is assembly-oriented and provides a generic modeling of irregular hardware constraints that are typical for many embedded processors. The generic modeling supports graph-based and search-based optimization...
متن کاملHPSG Grammar Treating of Different Forms of Arabic Coordination
Researchers working in Natural Language processing (NLP) found many problems, at different levels. The main problem encountered is the treatment of complicated phenomena, essentially the coordination. This phenomenon is very important. In fact, it is very frequent in various corpora and has always been a center of interest in NLP. Unfortunately, the few works working on this structure treated o...
متن کاملConstruction of an HPSG grammar for the Arabic language and its specification in TDL
The construction of an HPSG grammar (Headdriven Phrase Structure Grammar) treating Arabic specificities is not an easy task. In fact, several syntactic phenomena must be taken into account. Thus, the main objective of this work is to construct an Arabic HPSG grammar based on a proposed type hierarchy that categorizes Arabic words. In fact, some adaptations were introduced to HPSG, at the level ...
