Dynamic Stopwording for Story Link Detection
نویسنده
چکیده
Carnegie Mellon University entered two systems in the Story Link Detection track of the 2001 Topic Detection and Tracking (TDT) evaluation. These systems were one of our systems from the 1999 TDT evaluation [1], retuned for the new corpus, which had the third-best cost measure; and a new system that adds clustering and dynamically-generated stopwording, which had the best cost measure among all submissions for the default evaluation condition. This paper describes the enhancements which were made and some which were attempted but not used in the evaluation.

Story Link Detection based on Dynamic Information Extending
Topic Detection and Tracking refers to automatic techniques for locating topically related materials in streams of data. As the core technology of it, story link detection is to determine whether two stories are about the same topic. To overcome the limitation of the story length and the topic dynamic evolution problem in data streams, this paper presents a method of applying dynamic informatio...
متن کاملApplying Dynamic Co-occurrence in Story Link Detection
Story link detection is part of a broader initiative called Topic Detection and Tracking, which is defined to be the task of determining whether two stories, such as news articles or radio broadcasts, are about the same event, or linked. In order to mine more information from the contents of the stories being compared and achieve a more high-powered system, motivated by the idea of the word co-...

متن کاملMaximum Allowable Dynamic Load of Flexible 2-Link Mobile Manipulators Using Finite Element Approach
In this paper a general formulation for finding the maximum allowable dynamic load (MADL) of flexible link mobile manipulators is presented. The main constraints used for the algorithm presented are the actuator torque capacity and the limited error bound for the end-effector during motion on the given trajectory. The precision constraint is taken into account with two boundary lines in plane w...
متن کاملStory Link Detection and New Event Detection are Asymmetric
Story link detection has been regarded as a core technology for other Topic Detection and Tracking tasks such as new event detection. In this paper we analyze story link detection and new event detection in a retrieval framework and examine the effect of a number of techniques, including part of speech tagging, new similarity measures, and an expanded stop list, on the performance of the two de...
