| Component | Details |
| Morphological | Consists of approximately 317,000 inflected items |
| Analyzer and | derived from over 90000 stems. |
| Morph Database | Entries are indexed on the inflected form and return |
| the root form, POS, and inflectional information. | |
| POS Tagger | Wall Street Journal-trained trigram tagger ([#!kwc88!#]) |
| and Lex Prob | extended to output N-best POS sequences |
| Database | ([#!soong90!#]). Decreases the time to parse |
| a sentence by an average of 93%. | |
| Syntactic | More than 30,000 entries. |
| Database | Each entry consists of: the uninflected form of the word, |
| its POS, the list of trees or tree-families associated with | |
| the word, and a list of feature equations that capture | |
| lexical idiosyncrasies. | |
| Tree Database | 1004 trees, divided into 53 tree families and 221 individual |
| trees. Tree families represent subcategorization frames; | |
| the trees in a tree family would be related to each other | |
| transformationally in a movement-based approach. | |
| X-Interface | Menu-based facility for creating and modifying tree files. |
| User controlled parser parameters: parser's start category, | |
| enable/disable/retry on failure for POS tagger. | |
| Storage/retrieval facilities for elementary and parsed trees. | |
| Graphical displays of tree and feature data structures. | |
| Hand combination of trees by adjunction or substitution | |
| for grammar development. | |
| Ability to manually assign POS tag | |
| and/or Supertag before parsing |
