Translation capability of a Phrase-Based Statistical Machine Translation (PBSMT) system mostly depends on parallel data and phrases that are not present in the training data are not correctly translated. This paper describes a method that efflciently expands the existing knowledge…

With the development of Web 2.0, more and more people contribute their knowledge to the Internet. Many general and domain-specific online encyclopedia resources become available, and they are valuable for many Natural Language Processing (NLP) applications, such as summarization and…

We give an elementary proof of the Liouville theorem, which allows us to obtain n constants of motion in addition to n given constants of motion in involution, for a mechanical system with n degrees of freedom, and we give…

In this study we present a pilot-investigation of high-school and university students' abilities to solve partially specified physics problem and ways which they handle the task. Students are asked to answer the question whether the given problem situation is physically…

This paper addresses some lexical issues in the development of XUNL - a knowledge representation language descendent from and alternative to the Universal Networking Language (UNL). We present the current structure and the role of Universal Words (UW) in UNL…

The necessity of verification tools for Knowledge Based-Systems (KBSs), that help to guarantee a certain degree of quality and reliability of these systems will increase in the future when more critical systems are developed in areas such as industry, science,…

In this paper, we propose semantic enterprise search as promising technical methodology for improving on accessibility to institutional knowledge. We briefly discuss the nature of knowledge and ignorance in respect to web-based information retrieval before introducing our particular view on…

OBJECTIVE:To assess Mexico City physicians' knowledge and practices regarding cervical cancer and human papillomavirus (HPV) to compare obstetricians/gynecologists (ob/gyns) and general practitioners (GPs) on these variables MATERIAL AND METHODS: In April 2003, 187 ob/gyns and GPs working in 15 hospitals…

Automatic keyword extraction is an important subfield of information extraction process. It is a difficult task, where numerous different techniques and resources have been proposed. In this paper, we propose a generic approach to extract keyword from documents using encyclopedic…

In this paper we present a very simple derivation of the constants of motion for dynamical systems, which requires only an elementary knowledge of the theory of continuous groups. In addition, through the infinitesimal Lorenz transformations group, we obtain a…
