Topic Detection and Tracking

TDT Phase 3

• Corpus Overview

Provides a brief overview of data developed for TDT Research.
• Corpus components and data formats

Explains the various types of data files comprising the corpus, how they are organized and formatted.
• Evaluation Plan and Software (@NIST)

Explains the evaluation methodology in detail and reports on previous TDT research results.
• TDT3 Topic Descriptions

Note that these pages were developed for use by LDC annotators.  Topic ID numbers and rules of interpretation on these pages reflect internal annotation practices in place at the time the topics were developed. Mapping from original rules of interpretation to current rules of interpretation is presented here. Original rules of interpretation are presented in the TDT3 annotation guide. Revised rules of interpretation are presented in the TDT4 annotation guide.
