11 Basic TEI mark-up for our text files

12 More TEI mark-up? three basic groups of structural features –defining idiosyncrasies in transcription –links to analytic annotation and other data types (e.g.. thematic codes, concepts, audio or video links, researcher annotations) –identifying information such as real names, company names, place names, occupations, temporal information we have piloted an NLP system to semi-automated mark up of named entities

13 13 Identifying elements –identify atomic elements of information in text Person names Company/Organisation names Locations Dates Times Percentages Occupations Monetary amounts –example: Italy's business world was rocked by the announcement last Thursday that Mr. Verdi would leave his job as vice-president of Music Masters of Milan, Inc to become operations director of Arthur Anderson
