Dewey.info is an experimental space for linked DDC data. The initial data set available is a
linked data version of the DDC Summaries in nine languages. The intention of the dewey.info prototype
is to be a platform for Dewey data on the Web.
LIBLINEAR is a linear classifier for data with millions of instances and features. It supports L2-regularized logistic regression (LR), L2-loss linear SVM, and L1-loss linear SVM.
Main features of LIBLINEAR include
* Same data format as LIBSVM, our general-purpose SVM solver, and also similar usage
* Multi-class classification: 1) one-vs-the rest, 2) Crammer & Singer
* Cross validation for model selection
* Probability estimates (logistic regression only)
* Weights for unbalanced data
* MATLAB/Octave, Java interfaces

There is no official classification of prokaryotes, but the names given to prokaryotes are regulated. This website includes the nomenclature of prokaryotes and the nomenclatural changes as cited in the literature.
Provides biodiversity knowledge about all known species, including their taxonomy, geographic distribution, collections, genetics, evolutionary history, morphology, behavior, ecological relationships, and importance for human well being.
The Cataloging Lab is a place for catalogers and anyone who cares about library metadata to experiment with creating better controlled vocabularies. Suggesting additions and changes to the Library of Congress Subject Headings vocabulary can be an isolating endeavor—it can be difficult to determine if your heading has already been proposed or if someone else is working on a proposal at the same time you are. The Cataloging Lab is designed to be a wiki where folks can collaborate on headings together to create stronger proposals.
There are many different folk tales in the world, but many tales are variations on a limited number of themes. The classification system originally designed by Aarne, and later revised first by Thompson and later by Uther, is intended to bring out the similarities between tales by grouping variants of the same tale under the same ATU category. like hraf
Diese Einführung soll die Nutzung der Beschreibungssprache Simple Knowledge Organization System (SKOS) für kontrollierte Vokabulare erleichtern. Wir diskutieren den Zweck und die Vorteile am Beispiel von Open Educational Resources (OER).
Diese Seite beinhaltet einen theoretischen Überblick. Wer direkt praktisch einsteigen möchte, kann im Tutorial ein SKOS-Vokabular von Grund auf erstellen und veröffentlichen.

The New Opportunities Made Possible Through Ease of Access to Scholarly and Research Data and Information
Summary: The ever-greater online availability of data and information is tending to what we might characterize as syntactic completeness. That is to say, we have an ever-better knowledge of all possible data and ensuing information in the particular domain of scholarly research. In this position statement, we note how the mathematical and computational modelling of data and information are crucial for semantic completeness. Use of data and information implies a well-elaborated understanding of both their syntax and their semantics. More transparent and hence better quality evaluation of both product and process is made possible.
Social tagging, which is also known as collaborative tagging, social classification, and social indexing, allows ordinary users to assign keywords, or tags, to items.
Libtextcat is a library with functions that implement the classification technique described in Cavnar & Trenkle, "N-Gram-Based Text Categorization" [1]. It was primarily developed for language guessing, a task on which it is known to perform with near-pe
