Overview of the TAC 2008 Update Summarization Task



Hoa T. Dang, Karolina K. Owczarzak


The summarization track at the Text Analysis Conference (TAC) is a direct continuation of the Document Understanding Conference (DUC) series of workshops, focused on providing common data and evaluation framework for research in automatic summarization. In the TAC 2008 summarization track, the main task was to produce two 100-word summaries from two related sets of 10 documents, where the second summary was an update summary. While all of the 71 submitted runs were automatically scored with the ROUGE and BE metrics, NIST assessors manually evaluated only 57 of the submitted runs for readability, content, and overall responsiveness.
