BiOSS: A system for biomedical ontology selection

In biomedical informatics, ontologies are considered a key technology for annotating, retrieving and sharing the huge volume of publicly available data. Due to the increasing amount, complexity and variety of existing biomedical ontologies, choosing the ones to be used in a semantic annotation problem or to design a specific application is a difficult task. As a consequence, the design of appro...

A Flexible Biomedical Ontology Selection Tool

The wide adoption and reuse of existing biomedical ontologies available in various libraries is limited by the lack of suitable tools with metrics for their evaluation by both naïve users and expert ontologists. Existing evaluation tools perform technical evaluation of the structure of an ontology as presented by its design and knowledge representation. These find little use in evaluating the p...

A System for Ontology-Based Annotation of Biomedical Data

We present a system for ontology based annotation and indexing of biomedical data; the key functionality of this system is to provide a service that enables users to locate biomedical data resources related to particular ontology concepts. The system’s indexing workflow processes the text metadata of diverse resource elements such as gene expression data sets, descriptions of radiology images, ...

Fast SFFS-Based Algorithm for Feature Selection in Biomedical Datasets

Biomedical datasets usually include a large number of features relative to the number of samples. However, some data dimensions may be less relevant or even irrelevant to the output class. Selection of an optimal subset of features is critical, not only to reduce the processing cost but also to improve the classification results. To this end, this paper presents a hybrid method of filter and wr...
