Description of Ntu Approach to Link Detection Task in Tdt2001
نویسندگان
چکیده
We participated in the link detection task and submitted four runs, including both manual and ASR transcription for audio resources; and both English translation and original Chinese character source stream for Mandarin sources. This paper will propose a method to tell if a pair of news stories discusses the same topic. Several issues are addressed, e.g., how to represent a news story, how to measure the similarity of news stories, how to expand a story vector using history information, how to identify the subtopics embedded in a news story, and how to deal with news stories in different languages. The experimental results of TDT2001 official evaluation are also discussed.

A Novel Fault Detection and Classification Approach in Transmission Lines Based on Statistical Patterns
Symmetrical nature of mean of electrical signals during normal operating conditions is used in the fault detection task for dependable, robust, and simple fault detector implementation is presented in this work. Every fourth cycle of the instantaneous current signal, the mean is computed and carried into the next cycle to discover nonlinearities in the signal. A fault detection task is complete...
متن کاملThe Limsi Topic Tracking System for Tdt2001
In this paper we describe the LIMSI topic tracking system used for the DARPA 2001 Topic Detection and Tracking evaluation (TDT2001). The system relies on a unigram topic model, where the score for an incoming document is the normalized likelihood ratio of the topic model and a general English model. In order to compensate for the very small amount of training data for each topic, document expan...
متن کاملTask-space Control of Electrically Driven Robots
Actuators of robot operate in the joint-space while the end-effect or of robot is controlled in the task-space. Therefore, designing a control system for a robotic system in the task-space requires the jacobian matrix information for transforming joint-space to task-space, which suffers from uncertainties. This paper deals with the robust task-space control of electrically driven robot manipula...

متن کاملRelationship Between EFL Learners’ Self-Perceived Communication Competence and Their Task-Based and Task-Free Self-Assessment of Speaking
Self-assessment and task-based assessment have recently attracted attention in language learning and testing contexts worldwide; however, little research has been carried out to document the link between these notions. The present research was an attempt to investigate the connection between task-free/task-based self-assessment and learners’ self-perceived communicative competence in speaking. ...
