Abstract

An error detection and correction system extracts editing patterns and derives correction rules from them by observing differences between draft documents and corresponding edited documents, and/or by observing editing operations performed on the draft documents to produce the edited documents. The system develops classifiers that partition the space of all possible contexts into equivalence classes and assigns one or more correction rules to each such class). Once the system has been trained, it may be used to detect and (optionally) correct errors in new draft documents. When presented with a draft document, the system identifies first content (e.g., text) in the draft document and identifies a context of the first content. The system identifies a correction rule based on the first content and the first context. The system may use a classifier to identify the correction rule. The system applies the correction rule to the first content to produce second content.

Claims

1. A computer-implemented method for editing a first document, the method comprising steps of:

(A) identifying first content in the document;

(B) identifying a first context of the first content;

(C) identifying a correction rule based on the first content and the first context; and

(D) applying the correction rule to the first content to produce second content.
