This paper discusses the important issue of knowledge base comprehensibility and describes a technique for comprehensibility improvement. Com-prehensibility is often measured by simplicity of concept description. Even in the simplest form, however, there will be a number of dierent DNF (Disjunctive Normal Form) descriptions possible to represent the same concept, and each of these will have a d...

Data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) with multiple inputs and multiple outputs. DEA-based Malmquist productivity index measures the productivity change over time. We propose a dynamic DEA model involving network structure in each period within the framework a DEA. We have previously published the network DEA (NDEA) and the dynamic DEA ...

The exponential growth of the Internet has produced a labyrinth of documents , databases and services. While almost any type of information is available somewhere, even expert users waste time and eort searching for appropriate information sources, and phrasing queries in the custom formats required by each site. To make matters worse, many queries can only be answered by combining information ...

This article deals with the relationship existing between the emotional aspect and decision-making processes. More specifically, it examines the links between emotional intelligence, decision biases and effectiveness of the governance mechanisms. The primary purposes of this article are to: consider emotional intelligence like new research ideas that make important contributions to society; off...

Augmented reality(AR) focuses on the interraction in dealing wih the real world. Science frontiers has investigated studying the human and augmented real world interactins but did not consider much i n traction using the AR system. We propose a communication technique which will use by h umans and a virtual world model to share a complex world model constructed from some real world models. For ...

Multiuser museum interactives are computer systems installed in museums or galleries which allow several visitors to interact together with digital representations of artefacts and information from the museum?s collection. In this paper, we describe We-Curate, a socio-technical system that supports co-browsing across multiple devices and enables groups of users to collaboratively curate a colle...

|This paper describes concept and realization of IRoN (Inter Robot Network), a wireless communication network to support cooperation among mobile robots. From the point of view of the user (application programmer), IRoN has the following features: A list of surrounding robots with current position and speed is always available (by so-called implicit communication). Additionally, communication w...

— Caussinus’s loglinear model of quasi symmetry has interesting connections with models for within-subject effects with repeated categorical measurement. For binary responses, Tjur (1982) showed that estimates of main effect parameters in the quasi-symmetry model are also conditional maximum likelihood estimates of item parameters for a fixed effects treatment of subject terms in the Rasch item...
