50+ Metrics for Calendar Mining

Closed Pattern Mining for the Discovery of User Preferences in a Calendar Assistant

We use closed pattern mining to discover user preferences in appointments in order to build structured solutions for a calendar assistant. Our choice of closed patterns as a user preference representation is based on both theoretical and practical considerations supported by Formal Concept Analysis. We simulated interaction with a calendar application using 16 months of real data from a user’s ...

Falling behind: life expectancy in US counties from 2000 to 2007 in an international context

BACKGROUND The United States health care debate has focused on the nation's uniquely high rates of lack of insurance and poor health outcomes relative to other high-income countries. Large disparities in health outcomes are well-documented in the US, but the most recent assessment of county disparities in mortality is from 1999. It is critical to tracking progress of health reform legislation t...

Combining Ontology Alignment Metrics Using the Data Mining Techniques

Several metrics have been proposed for recognition of relationships between elements of two Ontologies. Many of these methods select a number of such metrics and combine them to extract existing mappings. In this article, we present a method for selection of more effective metrics – based on data mining techniques. Furthermore, by having a set of metrics, we suggest a data-mining-like means for...

Metrics for Evaluation of Student Models

Researchers use many different metrics for evaluation of performance of student models. The aim of this paper is to provide an overview of commonly used metrics, to discuss properties, advantages, and disadvantages of different metrics, to summarize current practice in educational data mining, and to provide guidance for evaluation of student models. In the discussion we mention the relation of...
