Different proposals have been made in recent years to exploit Social Web tagging data to improve recommender systems. The tagging data was used for example to identify similar users or viewed as additional information about the recommendable items. In this work we propose to use tags as a means to express which features of an item users particularly like or dislike. Users would therefore not on...

Measures for assessing the environmental impact and long-term sustainability will become an increasingly important requirement in industrial project management. The concept of sustainability influences all aspects of a project, from its earliest phases: development procedures, design of facilities and infrastructure, operation of the industrial facility, and economics. Project management resear...

PURPOSE OF THE STUDY In 2008, the Centers for Medicare and Medicaid Services (CMS) implemented a five-star rating system of nursing homes in the United States. These star ratings have been widely publicized both by CMS and the national and state media. Although the components of the star rating system take into account various dimensions of quality, satisfaction of nursing home residents and th...

Game-theoretic models typically associate outcomes with real valued utilities, and rational agents are expected to maximize their expected utility. Currently fielded agent rating systems, which aim to order a population of agents by strength, focus exclusively on games with discrete outcomes, e.g., win-loss in two-agent settings or an ordering in the multi-agent setting. These rating systems ar...

A systematic and effective welfare system for people with digestive system impairments is required. In Korea, an objective and scientific rating guideline does not exist to judge the digestive system impairments. Whether the impairments exist or not and the degree of it need to be examined. Thus, with these considerations we need a scientific rating guideline for digestive system impairments to...

In this paper we propose a new methodology for evaluating the relative power of agents in a strategic situation formally represented by a boolean game. The methodology consists in extracting a power ranking from the dependence relation induced by a certain boolean game. Our approach is axiomatic. We provide a number of desirable postulates that a notion of dependence is expected to satisfy and ...

Based on the Open Data Charter of G8 in 2013, the Japanese government published a dataset covering approximately 4.4 million corporations in December 2015, but the dataset is merely rated as 3-star in the 5-star rating system of Open Data. To improve usability, we defined a schema for corporation data, converted the dataset into 5-star using this schema, and published the created dataset under ...
