A novel fuzzy result ranking technique

Perspective: Essential study quality descriptors for data from nutritional epidemiologic research

Pooled analysis of secondary data increases the power of research and enables scientific discovery in nutritional epidemiology. Information on study characteristics that determine data quality is needed to enable correct reuse and interpretation of …

Fusion of preferences from different perspectives in a decision-making context

Combining quantifications for flexible query result ranking

Databases contain data and database systems governing such databases are often intended to allow a user to query these data. On one hand, these data may be subject to imperfections, on the other hand, users may employ imperfect query preference …

Exploring dance movement data using sequence alignment methods

Despite the abundance of research on knowledge discovery from moving object databases, only a limited number of studies have examined the interaction between moving point objects in space over time. This paper describes a novel approach for measuring …

Movement pattern analysis based on sequence signatures

Increased affordability and deployment of advanced tracking technologies have led researchers from various domains to analyze the resulting spatio-temporal movement data sets for the purpose of knowledge discovery. Two different approaches can be …

A method based on shape-similarity for detecting similar opinions in group decision-making

Handling bipolarity in elementary queries to possibilistic databases

Making data-querying and representation easier and more human consistent is an important research topic. In this context, fuzzy logic with its capability to model linguistic expressions provides an interesting framework, which has been adopted by …

The bipolar semantics of querying null values in regular and fuzzy databases: dealing with inapplicability

Dealing with missing information in databases, either because the information is unknown or inapplicable, is a widely addressed topic in research. Most of the time, null values are used to model this missing information. This paper deals with …

Impact of weights on conjunctive and disjunctive aggregation of extended possibilistic truth values
