The workshop will explore the potential of Knowledge Organization Systems (KOS), such as classification systems, taxonomies, thesauri, ontologies, and lexical databases, in the context of current developments and possibilities. These tools help model ...

The problem of thematic indexing of Open Educational Resources (OERs) is often a time-consuming and costly manual task, relying on expert knowledge. In addition, a lot of online resources may be poorly annotated with arbitrary, ad-hoc keywords ...

VocBench is an open source web platform for the collaborative development of datasets complying with Semantic Web standards. Since its public release – five years ago – as an open source platform, VocBench has attracted a growing user community consisting ...

Search strategies for Learning Objects (LOs) in repositories, by using purely syntactic structures, can make that task of searching and retrieval become time-consuming and unproductive, and consequently can decrease the possibilities for reuse of these ...

Much of the literature of information science and knowledge organization has accepted and built upon Elaine Svenonius's 2004 claim that "paradigmatic relationships are those that are context-free, definitional, and true in all possible worlds" p. 583. ...

Thesauri are valuable knowledge organization systems (KOSs) that support advanced information retrieval. The Semantic Web has brought a renewed interest in thesauri as a support for semantic searches and other added-value services. Tools that manage ...

One of the main holdbacks towards a wide use of ontologies is the high building cost. In order to reduce this effort, reuse of existing Knowledge Organization Systems (KOSs), and in particular thesauri, is a valuable and much cheaper alternative to ...

Background knowledge as provided by repositories such as WordNet is of critical importance for linking or mapping ontologies and related tasks. Since current repositories are quite limited in their scope and currentness, we investigate how to ...

SveMed+ is a bibliographic database covering Scandinavian medical journals. It is produced by the University Library of Karolinska Institutet in Sweden. The bibliographic references are indexed with terms from the Medical Subject Headings (MeSH) ...

In this paper we present the IRSA framework that enables the automatic creation of search term suggestion or recommendation systems (TS). Such TS are used to operationalize interactive query expansion and help users in refining their information need in ...

Knowledge organization systems such as thesauri or taxonomies are increasingly being expressed using the Simple Knowledge Organization System (SKOS) and published as structured data on the Web. Search engines can exploit these vocabularies and improve ...

A scheme is proposed to develop image processing and analysis software based on the generation of thesaurus tables in the interpreter's kernel. The scheme is based on the combined features of dynamic libraries and an interpreter with a set of functions ...

In this paper we describe a novel SKOS editor built on top of the web browser Mozilla Firefox. Our tool is targeted towards KOS developers and KOS consumers as well. Indeed, the ability to surf the Web with a standards compliant browser proves useful ...

In this paper we describe how Dicionáio-Aberto, an online dictionary for the Portuguese language, is being used as the base to construct diverse resources that are relevant in the processing of the Portuguese language.

We will briefly present its ...

In the recent years, research on terminology data sets standardization has been one of the biggest concerns of a World Wide Web Consortium working group. This research has led to the development of SKOS, a new standard which was subsequently issued in ...

The progressive increase of information content has recently made it necessary to create a system for automatic classification of documents. In this article, a system is presented for the categorization of multiclass Farsi documents that requires fewer ...

As part of the publication of the AGROVOC thesaurus as Linked Data (LD), AGROVOC is now mapped with six well-known thesauri in the agricultural domain, i.e., EUROVOC, NALT, GEMET, STW, LCSH, RAMEAU. To find matching candidates, known matching algorithms ...

Metadata is one of the keys for digital archiving and preservation. This is well recognized as an important issue in our networked information society. There are several standards for archival and preservation metadata, e.g. ISAD(G), EAD, AGRkMS, PREMIS,...

The classic approach to text categorisation is based on a learning process that requires a large number of labelled training texts to achieve an accurate performance. The most notable problem is that labelled texts are difficult to generate because ...

Information sharing, exchanging and archiving is the backbone of any organized activity, regardless if it is performed in the sphere of business, home or administration. Semantic Web technologies allow controlling the growth and structure of information,...
