Clustering errors into patterns
- Take quick stock of the kinds of errors that you've found. Cluster errors into groups--word choice, sentence punctuation (fragments, comma splices, run-ons), sentence structure (sentence appears to start in one direction and ends up somewhere else), agreement, reference, modification (misplaced words and phrases), internal punctuation (comma use, dashes, apostrophes), spelling, idiomatic lapses, missing or misused articles.
- Read through the remaining text to see if you spot new kinds of errors and mark those. Don't mark exhaustively any of the categories you've already identified.
