This paper describes a generic, knowledge-based mechanism used to make selections between a xed set of alternatives. The mechanism, termed sponsor-selector has been used as a control mechanism in a number of diierent knowledge-based systems including design, planning and problem-solver integration applications. We will discuss the general applicability of the sponsor-selector mechanism and desc...

In this paper, content-based image retrieval (CBIR) for content-based image mining is proposed. Here, an approach of image detection in a image dataset and an improved histogram based approach for Correlative Histogram Features named as Correlative Histogram based Coding (CR-HBC) is proposed. The proposed approach enhances the objective of processing noise and system overhead with respect to th...

Quality assurance remains a key topic in human computation research field. Prior work indicates independent agreement is effective for low difficulty tasks, but has limitations. This paper addresses this problem by proposing a tournament selection based quality control process. The experimental results from this paper show that the human are better at identifying the correct answers than produc...

The focus of the research is mainly methodological. The goal is to develop a framework for comparing computational, agent-based models for land-use decision making. The framework will allow studying spatial patterns emerging from different distributions of agent characteristics, learning and communications schemes, initial spatial configurations, and varying spatial suitabilities. The framework...

We propose a Case-Based Reasoning approach for action selection in the robot soccer domain presented in the 8th European Conference on Case-Based Reasoning (2006). Based on the current state of a game, the robots retrieve the most similar past situation and then the team reproduces the sequence of actions performed in that occasion. In this domain we have to deal with all the difficulties that ...
