Solving problem of ambiguity terms using ontology

Humans as God's creatures were endowed with brain used to think and to process the received knowledge. Human brain links knowledge into a giant network of ideas, memories, predictions and beliefs. Everything is interconnected in the brain. Human can understand the meaning of the same variable even if that variable has an ambiguous meaning. In another scenario, humans can understand the same thing based on different terms. People can argue and debate with one another about any problem to get a better solution. The different understanding of terms is not a big problem for human brain but imagine if it happens between computers or between humans and computers! Based on this problem we want to provide a model of managing knowledge in situations where terms can generate ambiguity. Knowledge representation process is a good approach to organize and share knowledge. We use ontologies as a technique to represent the particular knowledge stored in each computer and to find correspondences between the concepts used in those ontologies.(undefined

STUDENT’S DIFFICULTIES IN SOLVING PROBLEM OF REAL ANALYSIS

Main goal of learning mathematics is students able to solve mathematics problems. Students acquire high order thinking, e.g. critical and creative thinking, by solving mathematical problems. Students also acquire habits of persistent and confidence in unfamilitar conditions (NCTM, 2000). Actually, university students of mathematics education had difficulties to solve a problem to prove of Real Analysis. Subjects of the lecture can help students to have ways of mathematical thinking. The aim of this research was to describe difficulties of students to solve a Real Analysis problem. Three students had solved a problem while being interviewed by the researcher. The interview was based on Polya’s heuristic of problem solving. The activities was recorded by audiotape. The results were all students understand the problem. They could determine what is known and target/unknown of the problem. One of the students also had known concepts in the problem, but she could not synthesize the concept to make a plan. Students lack in having problem solving scheme. It is interwining between concepts in the problem and strategy of previous solved problems

The referee assignment problem

In collaboration between a UPC spinoff, Barcelogic, and the Dutch Football Federation (KNVB), we define, study, implement and evaluate different approaches for solving the so-called Referee Assignment Problem(RAP). In this NP-complete constraint solving problem, numerous conditions must be met, such as the balance in the number of matches each referee must officiate, the frequency of each referee being assigned to a given team, the distance each referee must travel over the course of a season, etc

Comparison of PBO solvers in a dependency solving domain

Linux package managers have to deal with dependencies and conflicts of packages required to be installed by the user. As an NP-complete problem, this is a hard task to solve. In this context, several approaches have been pursued. Apt-pbo is a package manager based on the apt project that encodes the dependency solving problem as a pseudo-Boolean optimization (PBO) problem. This paper compares different PBO solvers and their effectiveness on solving the dependency solving problem.Comment: In Proceedings LoCoCo 2010, arXiv:1007.083

Solving problem of semantic terminology in digital library

Effective information access involves the semantic interaction between users in searching activity to diverse information in the Digital Library. This is the focus of this research. The weakness of the online library system that is running is the difficulty of users looking for data collection library. There are many different perceptions that have the same meaning (synonym) in in terms of library collections such as Author and Writer. Therefore, in this research will focus on mapping between terminologies that supports to detect different meaning of perceptions .This technique can be considered as an attempt to understand the difference between perceptions in the interaction between users and information in digital libraries
