Annotators must be careful to make sure that story boundaries are marked where they need to be, adding marks where necessary. For example, an announcer may utter two or three independent, informative clauses reporting a brief news item, but the closed caption text will contain none or only one of these cluases. Segments marked in this way will not be treated during the topic labeling stage of annotation. Categorize each boundary with respect to the nature of the material that follows the boundary, as either a news report, as untranscribed news, or as non-news. When the audio segmentation has been completed for a given episode, the modified text file is filtered to produce the common TDT2 SGML format.
Every file is gone over twice, with the second pass being done by a different annotator.
