Abstract

The first part of the Spanish translation and adaptation of the ISO 25964 Information and documentation standard is analyzed: Thesauri and interoperability With Other vocabularies - Part 1: Thesauri for information retrieval will become the new UNE ISO 25964-1. Innovations and implications are presented and discussed, with particular attention to the developments that have been implemented toensure that thesauri become fully interoperable technically and linguistically, so that all the advantages that they offer in an increasingly globalized and interconnected environment can be promoted, offering their strengths to the Semantic Web project.

Abstract

Schema.org is an important initiative that advances in two directions: on one hand, towards information retrieval normalcy on the world wide web, where fields and vocabulary control are used to improve recall and precision in addition to other logical, vector and probabilistic tools; and, on the other hand, the democratization of the semantic web or, in other words, the launch of a semantic web that can be easily adopted by any willing web master, which now can be almost any person with access to the internet.

Abstract

Lexical representation of information has adapted to the conditions imposed by the Web on information generation and traffic. Systems based on controlled words or terms now coexist with others that have a conceptual and therefore semantic nature. The latter have experienced a decisive progression toward concept management, as thesauri have become semantic networks made possible by domain ontologies. The challenges arise in the processing of these concepts, their associative links, and their interoperability.

Abstract

We show the first steps of the initiatives Open data and Linked open data as sources of innovation in the field of information management. As the Open Access  movement (OA) and the Open Archives Initiative (OAI) implied some years ago, these two  initiatives constitute a shock that reverberated in technological innovation and the structure of the Web. We present a global overview of open data  and national projects related to government data. Four Spanish local or regional administrations have already begun to release their data: in chronological order, Asturias, Euskadi, Zaragoza and Catalonia. In the case of Linked open data  we also provide a global picture, with 203 registered projects. We describe in more detail the work that the W3C is currently carrying out in the field of libraries. Finally we present the consecuences these new developments can have for librarianship and information science.
