Textual Entailment (TE) is the task of recognizing entailment, paraphrase, and contradiction relations between a given text pair. The goal of textual entailment research is to develop a core inference component that can be applied to various domains such as QA. We observed several rank correlations on the data and system results in the NTCIR-10 RITE-2 task, trying to find out correlations between...
Textual Entailment (TE) is the task of recognizing entailment, paraphrase, and contradiction relations between a given text pair. The goal of textual entailment research is to develop a core inference component that can be applied to various domains, such as IR or NLP. Since the domain that a TE system applies to may be different from its source domain, it is crucial to develop proper datasets for...
In this paper, an overview of stereo vision, stereo image processing is introduced as well as a method of navigation based on stereo vision for mobile robot is provided. Making use of 3-d stereo reconstruction, the recognition of visible terrain in front of the mobile robot is solved for successive obstacle avoidance. The area-based stereo reconstruction algorithm which combines the pyramidal data...
How to share knowledge within the team to increase team effectiveness has become a focus in theory and business circles. Basing on the literature review, this paper starts with personal factors that affect knowledge sharing within the team, and uses questionnaires, interviews, other research methods and SPSS analysis to make a systematic analysis of individual factors that affect knowledge sharing...

Using grey correlation analysis to the relationship between the incidence of liver cancer and drinking water quality in Fujian , Jiangsu , and Guangxi provinces, considering the basic features of the original and the secondary environments in the study areas, the following conclusions can be drawn: liver cancer can be caused by many factors and drinking water may be among the most important ones;...
From the perspective of Chinese investors, the exchange risk exposures and hedge ratios for international investments in G5 stock markets from August 2006 to February 2009 have been estimated with Adler-Dumas model. The empirical results show that for most currencies except sterling, the exchange exposures of individual stock market indices are not equal to 1, and the exposures of equally weighted...
In this paper, we propose an improved rate control scheme for low delay H.264 video coding. A fast and best selection of initial QP is first proposed in the GOP layer rate control. Then, an improved MAD prediction model and overhead bits prediction method is adopted in the MB layer rate control. The simulation results show that the proposed scheme gives an average PSNRY gain of about 0.55 dB when...
