Frame-slot architecture for data conversion

摘要

A machine based tool and associated logic and methodology used in converting data from an input form to a target form using context dependent conversion rules. A frame-slot architecture is utilized where a frame represents an intersection between a contextual cue recognized by the machine tool, associated content and related constraint information to specific to that conversion environment. A slot represents an included chunk of information. An exemplary conversion system (400) includes a parser (402) for use in parsing and converting an input stream (403) to provide an output stream (411) in a form for use by a target system (412). The parser (402) uses information from a public schema (406), a private schema (408) and a grammar (410). The public schema (406), private schema (408) and grammar (410) may include conversion rules applicable to less than the whole of a subject matter area including the input stream (403).

主权项

1. A method for use in operating a machine-based tool for converting data from a first form to a second form, comprising the steps of:
establishing, based on external knowledge of a subject matter area independent of analysis of a particular data set to be converted, a number of schema, each including one or more conversion rules for use in converting data within a corresponding context of said subject matter area; identifying a set of data to be converted from said first form to said second form;accessing at least a first schema of said number of schema;obtaining at least one contextual cue corresponding to a particular context regarding said set of data from a source external to said set of data, wherein said particular context corresponds to said subject matter area of said first schema; and
using an included conversion rule of said first schema in a process for converting said set of data from said first form to said second form.
