The environment is in particular oriented towards exploring dynamic aspects of parsing. It includses a number of specialized tools that consent an easy graphics-based interaction with the parser. It is shown in particular how a combination of the characteristics of the parser based on the lexicon and on dynamic unification and of the environment allow a nonspecialized user to explore heuristics that may alter the basica control of the system. In this way for instance a psycholinguist may explore ideas on human parsing strategies or a language engineer may find useful heuristics for parsing within a particular application. 1. Introduction Computer-based environments for the linguist are conceived as sophisticated workbenches built on Al workstations around a specific parser where the linguist can try out his her ideas about a grammar for a certain natural language. In doing so he she can take advantage of rich and easy-to-use graphic interfaces that know about linguistics. Of course behind all this lies the idea that cooperation with linguists will provide better results in NLP. To substantiate this assumption it may be recalled that some of the most interesting recent ideas on syntax have been developed by means of joint contributions from linguists and computational linguists. Lexical-Functional Grammar Bresnan Kaplan 1982 GPSG Gazdar 1981 Functional Grammar Kay 1979 DCG Pereira Warren 1980 TAG Joshi Levy 1982 are some of these ideas. Instances of the tools introduced above are the LFG environment which was probably the first of its kind an environment built by Ron Kaplan for Lexical-Functional Grammars DPATR built by Lauri Karttunen and conceived as an environment that would suit .
