This report summarizes our participation in the TREC 2006 spam track, in which we consider the use of Bayesian models for the spam filtering task. Firstly, our anti-spam filter, Kidult, is briefly introduced. And then we try to use weighted adjustment of separating hyperplane and selective classifiers ensemble to improve the filtering performance. Finally, we summarize the relevant results from...

This paper reports on Language Computer Corporation’s first QA@CLEF participation. For this exercise, we integrated our open-domain PowerAnswer question answering system with our statistical machine translation engine. For 2006, we participated in the English-to-Spanish, French and Portuguese cross-language tasks. We took the approach of intermediate translation, only processing English within ...

This article presents the first participation of the Laboratoire Informatique d’Avignon (LIA) to the Cross Language Evaluation Forum (CLEF). LIA participated to the monolingual Question Answering (QA) track dedicated to French language, and to the crosslingual English to French QA track. Two runs for each track were submitted. English questions were first translated and then answered by using t...

Diggery is a research and software project, investigating the extraction of concepts from well-written documents, with the idea of automating factoid search. The project is in its early to middle phases, and all information presented herein should be taken in light that this research is based on young software using new algorithms. In January 2006, after significant tuning, the software could a...

The demonstration not only showed the two current HDTV formats, 720p/50 and 1080i/25, but also introduced the next-generation HDTV format – 1080p/50. All three formats were presented with identical content and simultaneously on three Full-HD displays, in uncompressed and compressed form. Thus, viewers of the demonstration were able to judge the HDTV image quality for themselves. The overall goa...

This paper describes the participation of a mixed approach in GeoCLEF-2006. We have participated in Monolingual English Task and we present a joint work of three groups or teams belonging to project R2D2 1 with a new system, mixing the 3 individual systems of the teams.

The Dutch AIBO Team is a multi-institute team which competes in the 4-legged robot league of RoboCup since 2004. This team description paper briefly outlines the approach taken for the Passing and Open Challenge of the RoboCup 2006.

In this paper I detail the implementation of an extractionbased summarization system that uses sentence clustering and named entity identification as main features for the 2006 Multilingual Summarization Evaluation. I discuss some of the failings of my system, and what can be done to improve it.

This paper describes our experiments in the TREC 2006 Genomics track submitted by the ASU BioAI group, as well as experiments based on the improvements made after our submission. Some of the major issues we tried to address in our experiments are how to (1) extract keywords from natural language questions in the biomedical domain and (2) determine the relevancy of passages.

This paper describes the architecture and implementation of Tianwang QA system2006, which works for the TREC QA Main task this year. The main improvement is: 1. add one well founded knowledge source from Web – Wikipedia, and employ some natural language processing technologies to extract high quality answers; 2. design and implement a new translation algorithm in query generation. The results s...
