A new event detection and tracking system (NEDT) aims to determine the first story and tracking news for the new events among the news articles that arrive in temporal order. In this paper, after introducing NEDT systems we describe the construction of a test collection for measuring the effectiveness of such systems designed for Turkish. The collection contains more than 200 thousand news articles, time stamped at the detail level of hour and minute, downloaded from five different Web news resources. In the paper, we describe the design and construction of a semi-automatic system that helps determine the first story and tracking news, how we download the news, and some results on the distribution of the tracking news in the test collection.
