This paper presents a first step toward the formalization of the concept of document reliability in the context of Information Retrieval (and Information Filtering). Our proposal is based on the hypothesis that the evaluation of the relevance of a document can also depend on the concept of reliability of a document. This concept has the following properties: (i) it is user-dependent, i.e., a do...

Intercoder reliability is the most often used quantitative indicator of measurement quality in content studies. Researchers in psychology, sociology, education, medicine, marketing and other disciplines also use reliability to evaluate the quality of diagnosis, tests and other assessments. Many indices of reliability have been recommended for general use. This article analyzes 22, which are org...

OBJECTIVES A web-based survey has been administered annually since 2005 throughout Korea to assess the prevalence of adolescent health risk behaviors among middle and high school students. The aim of this study was to evaluate the test-retest reliability of the Korea Youth Risk Behavior Web-based Survey (KYRBWS) questionnaire. METHODS A convenience sample of 2298 middle and high school studen...

This paper proposes an optimization method for planning adequate number and location of automatic switches in a radial distribution system. The purpose is to maximize the profit of that service reliability indices achieve the required level. First, a network equivalent technique is introduced to calculate the reliability indices. Second, by using the equivalent method, system reliability indice...

This paper presents a method for assessing the voltage and reactive power control impact on the reliability indices of distribution networks. It has been achieved by including network constraints (voltage drop and feeder loading) in the predictive reliability model. The analytical method has been used to evaluate the reliability indices. The proposed method has been tested and validated, using ...
