Abstract

This paper presents a system of searching and recovering educational activities that follow the Web-Quest model through the web, complemented with a module to make semantic annotations aimed at getting and enriching the knowledge on the use of these exercises by the teaching community. It also tries to document the resources or websites with didactic interest in order to build a qualified account of educational links.

Abstract

The effective deployment of the semantic web depends not just on technological developments, but also on applying guidelines for the process of publishing structured data on the Web. Part of the work of the W3C working group about data on the Web is focused on the identification of best practices and defining vocabularies to represent datasets. The maturity of the semantic web is reflected in the increasing importance of aspects related to the use of published data, types of licenses, trust, publication dynamics, and data reusing, among other processes.

Abstract

The technologies of the semantic web have reached a high degree of development. There are hundreds of metadata schemes and ontologies and thousands of datasets available for public use. The next step is to improve access, reuse and trust on datasets. This article includes vocabularies for describing datasets (DCAT) and their provenance (PROV-O), specifying mechanisms for access and use of data (DUV), and defining quality indicators (DQV).

Abstract

DBpedia y Wikidata are two semantic projects built on the top of Wikipedia encyclopedic content that has been crowdsourced, created, and maintained by thriving online communities. This article outlines differences and similarities between these two projects, pointing out their data models, curation patterns, and technologies. In addition, it forecasts some possible trends for their co-evolution as crossdomain open knowledge graphs and their significant value as hubs of interlinking datasets of various domains.

Abstract

The semantic web has enough critical mass to expand its technological scope to content management systems (cms). Currently, an increase in the application of interoperable standards to publish large datasets is detected. Rdf, owl and sparql are replacing traditional developments based on relational database management systems for management and storage of information. Cms are beginning to use these technologies to publish content with semantic web formats, and to define mappings with elements of rdf vocabularies. In this regard, Cms also incorporate features to add semantic information into the xhtml code using rdfa and applying sparql to query data or incorporate external data.

Abstract

This paper shows some trends that are currently occurring in the environment of the semantic web. More specifically it presents schema.org, a project developed by Google, Yahoo and Bing for semantic markup using microdata, Freebase, a knowledge bank for structured information and Kasabi, a platform that operates into the modality of “Software as a Service” for the publication and commercial distribution of semantic data. It is possible see some technological divergence in the application of semantic Web standards with the development of new proposals as microdata, and the emergence of a market for linked data through publishing platforms that facilitate commercialization.

Abstract

This report highlights the most important recent activity in the field of semantic web, analyzing the most innovative aspects of the new RDF 1.1 recommendation, and discussing the first public working draft of Data on the web best practices. The evolution of semantic markup is analyzed, both from the point of view of standards and the practical applications on the Web. Wikipedia is identified as a dynamic factor in the semantic web, especially through the DBpedia and WikiData initiatives. Europeana and the Digital Public Library of America are clear references in the description of networked digital resources.

Abstract

In a Web dominated by social media for information, relationships and communication, the established dynamics between content, people and technology change radically. Given the relevance of the user-generated content in such a scenario and its essentially relational nature, successfully locating the best sources of information requires the development of recommender systems that incorporate the social characteristic of scenarios built on a network that goes beyond the original Internet. The article provides a review of current approaches to the process of recommendation, placing them in the context of consolidated trends associated with the phenomenon of Social Computing, and highlights some lines of development in the area of redefining the problem of recommendation in a context dominated by social networks and user-generated content.

Abstract

The discipline of information architecture (IA), although present in some way for over 50 years, has taken on special relevance with the advent of the Web and the explosion of the amount of available information. Nowadays, IA has clear pillars based on the managed content but especially on users, without forgetting the context. This article discusses components to combine when developing IA, and a basic methodology is identified. As the amount of information around us is still growing, IA continues to innovate with new forms of organization, more efficient search engines and Semantic Web technologies that let computers take care of the less creative part of coping with the avalanche of information.

Abstract

To some degree the Open Access Initiative has failed, because too few people, even in the library profession, know of its existence. More marketing should be done, thus making more people aware of it. MARC became obsolete and has to be superseded by xml-based standards. With the advent of Google, people don’t have any problems finding information. Instead they have problems knowing what to do with once they acquire it. A next generation library catalog should allow people to first find items in a library collection, and then to use the information in some way. Public libraries are devoted to their community. If they focus too much on books, then their future is less positive. If they think in terms of data, information, and knowledge, their future is only as limited as their imagination.
