- QUOTE: … Important genres that do not share these properties include instant messaging logs, newsgroup postings and email messages. We refer to these genres as “informal” text. Informal text is harder to process automatically. Informal documents do not obey strict grammatical conventions. They contain grammatical and spelling errors. Further, since the audience is more restricted, informal documents often use group- and task-specific abbreviations and are not self-contained. Because of these differences, existing NER methods may require modifications to perform well on informal text.
