transformational gr, m m a r on the S-structure level. (See appendix for some examplesD Structures of that type seem to us very suited for further semantic interpretation, since they offer a level of syntactic structure which both expresses ~'~mmatical functions (which are defined ~onfigurationally) and constituent structure features which axe important for certain aspects of logical form as scoping. Especially the use of the device of traces (as a phonologically empty phrase) allows for displaced elements to appear in the phrase marker in their surface postion and at the same time expresses the role which this element's. | AN ATN TREATMENT WH-MOVEMENT Hans Haugeneder Siemens AG ZTZTi Otto-Hahn-Ring 6 8 Mũnchen 83 West Germany ABSTRACT An ATN-Parser is presented with emphasis on the treatment of those phenomena which in the framework of transformational grammar are subsumed under the concept of WH-movement The approach taken tries to embed these constructions into an ATN grammar in a general linguistically motivated and in terms of the ATN grammar formalism descriptive way. To accomplish this goal the approach described incorporates the basic principles governing such constructions as formulated in the framework of the trace theory proposed in the development of the Extended Standard Theory EST . Thus a unified treatment for both relative clauses and wh-questions is achieved. 1 Overview The Grammar The ATN-Language used is - except for some minor deviations which are not of importance here -in accordance with the one specified in BATES 78 and covers the following subset of English - the most frequent verb types for declarative and imperative sentences and questions - directandindirectWH-questions forNPs PPs ADJPs AD VPs - direct and indirect Y N-questions - sentential complements for verbs and nouns - various types of relative clauses complete reduced. - infintive construction including control verbs with subject and nonsubject control - conjunction of complete constituents of every syntactic category - subordinate clauses The grammar is written in very compact way making extensively use of merging techniques it comprises about 75 states and 170 arcs. The structure built by the grammar is quite similar to the phrase structure trees used in transformational grammar on the S-structure level. See appendix for some examples Structures of that type seem to US very suited for further semantic interpretation since they offer a level of syntactic structure which both expresses grammatical functions which are defined configurationally and constituent structure features which are important
