------------------------------------------------------------------------------ LinGO Grammar Matrix $Id: README,v 1.13 2008-05-23 01:44:21 sfd Exp $ NB: This version of the Matrix requires LKB version $Date: 2008-05-23 01:44:21 $ or later. Changes since v 0.6: 1. Head types We had previously hesitated to posit head types, as we expect the exact subhierarchy under the type head to be language-specific, even for those head types that are found cross-linguistically. However, this hesitation was hampering our ability to develop lexical types for the Matrix. In this version, we have included 10 basic head types, as well as types for all possible disjunctive combinations for the basic 10. See further documentation near 'head' in matrix.tdl. Note that the disjunctive types are stored in a separate file head-types.tdl. We still have not posited any head features. In order to add features to one of the head types (disjunctive or otherwise) already defined in the Matrix, you'll need to use the new 'type addendum' syntax. (This is why a current LKB is required.) Type addenda can be used to add information (not override information) associated with previously defined types. They have :+ in place of :=. Type addenda can add parent types, constraints, or documentation strings, as long as they are consistent with the existing definition. As with subtypes, it is good practice to refrain from stating redundant information on type addenda. The LKB will print an error if a parent is declared redundantly. No such checking exists for constraints. NB: The :+ syntax is not yet supported in the PET system. 2. Lexical types (mostly from v 0.7) The Matrix now has a set of underspecified lexical types. Lexical entries are classified along multiple dimensions, including part-of-speech and subcategorization. Particular grammars can cross-classify these types to create the lexical types they need. We're particularly interested to learn about cases where additional types pa …
