Linked Data principles and technologies are being investigated in various areas. In the Educational context, many studies are using Linked Data trying to solve problems of interoperability of educational data and resources, enriching educational content, and personalizing and recommending educational content and practices. This article presents a…

Coding is a process of assigning meaning to a given piece of evidence. Evidence may be found in a variety of data types, including documents, research interviews, posts from social media, conversations from learning platforms, or any source of data that may provide insights for the questions under qualitative study. In this study, we focus on text…

Retrieving resources in an appropriate manner has a promising role in increasing the performance of educational support systems. A variety of works have been done to organize materials for educational purposes using tagging techniques. Despite the effectiveness of these techniques within certain domains, organizing resources in a way being…

The wide variety of readily available electronic media grants anyone the freedom to retrieve published references from almost any area of research around the world. Despite this privilege, keeping up with primary research evidence is almost impossible because of the increase in professional publishing across disciplines. Systematic reviews are a…

Purpose: The need of tools for content analysis, information extraction and retrieval of multimedia objects in their native form is strongly emphasized into the judicial domain: digital videos represent a fundamental informative source of events occurring during judicial proceedings that should be stored, organized and retrieved in short time and…

Introduction: This paper presents an analysis of the Simple Knowledge Organization System (SKOS) compared with other alternatives for thesaurus representation in the Semantic Web. Method: Based on functional and structural changes of thesauri, provides an overview of the current context in which lexical paradigm is abandoned in favour of the…

This article will discuss the issues concerning the storage, retrieval and use of multimedia technology in dance, and how semantic web technologies can support those requirements. It will identify the key aims and outcomes of four international telematic dance projects, and review the use of reflective practice to engage students in their learning…

The paper proposes a framework for building ontology-aware learning object (LO) content. Previously ontologies were exclusively employed for enriching LOs' metadata. Although such an approach is useful, as it improves retrieval of relevant LOs from LO repositories, it does not enable one to reuse components of a LO, nor to incorporate an explicit…

Expands on existing concepts and notions regarding hypertext-based information retrieval. Topics include document characterization; characterization networks; query by navigation; navigation networks; and adding new links to the characterization networks with information about semantic relations. (LRW)

Presents a faster method for determining hierarchical relationships in information retrieval by using trie structures instead of a linear storage of a concept code. Highlights include case structures, a knowledge representation for natural-language understanding with semantic constraints; a compression algorithm of tries; and evaluation.…

Discusses the logical approach to information retrieval that treats retrieval as inference, considers probabilistic models for text retrieval, and presents an approach for combining Datalog (a variant of Horn predicate logic) with probabilistic theory using intentional semantics with logical rules. Discusses syntax and semantics and compares this…

This paper provides a portrayal of Z39.50 (a communications protocol that enables two systems to exchange messages for the purpose of information retrieval) that explains its flexibility in response to a variety of information retrieval requirements in the networked environment. The first section presents an overview of Z39.50, including the…

Discussion of visualization for information retrieval, that transforms unseen internal semantic representation of a document collection into visible geometric displays, focuses on DARE (Distance Angle Retrieval Environment). Highlights include expression of information need; interpretation and manipulation of information retrieval models; ranking…

Presents an indexing and information retrieval method that, based on the vector space model, incorporates term dependencies and thus obtains semantically richer representations of documents. Highlights include term context vectors; techniques for estimating the dependencies among terms; term weights; experimental results on four text collections;…

Discusses thesauri as tools for multilingual information retrieval and cross-cultural communication. Considers the need for multilingual thesauri and the importance of explicit conceptual structures, and introduces a pilot thesaurus, InfoDEFT (Information Deutsch-English-Francais Thesaurus), as a possible model for new online thesauri which are…
