New version of CatMdEdit

Sunday, June 10th, 2012, Fco. Javier Zarazaga-Soria

We are very pleased to communicate the release of CatMDEdit (4.6.6 version) metadata editor under Open Source (GNU Lesser General Public) license. This application is an initiative of the National Geographic Institute of Spain (IGN), which is the result of the scientific and technical collaboration between IGN and the Advanced Information Systems Group (IAAA) of the University of Zaragoza with the technical support of GeoSpatiumLab (GSL).

CatMDEdit is a metadata edition tool that facilitates the documentation of resources, with special focus on the description of geographic information resources. The main new feature that this new version includes is a conversion gateway between MARC21 and ISO19115 standards. This conversion gateway is the result of the research carried out in the GTI PC-IDEE (Interdisciplinary Working Group on Cartographic Heritage in the SDI) in the context of the Spanish SDI Working Group (http://www.idee.es/en/web/guest/subgrupos-de-trabajo). The technical specifications of this work can be obtained at http://metadatos.ign.es/metadatos/Patrimonio_cartografico. In addition to that, new adaptations have been added to this version in order to guarantee the INSPIRE Implementation Rules compliance.

Zaragoza City Council launches a new version of its website

Tuesday, May 15th, 2012, Fco. Javier Zarazaga-Soria

The Zaragoza City Council has released today a new version of its website: http://www.zaragoza.es.

The new entry point provides direct access to a wide range of services for citizens displayed over the city map thanks to the Spatial Data Infrastructure of Zaragoza City Council technology (IDEZar).

On the right side of the Web page there is a drop down tab that allows the user to select among a broad volume of information about the city: news, mobility or municipal facilities an view it on the map.

This new development has been carried out together by the technical team of Zaragoza City Council Website, the Advanced Information Systems Laboratory from the University of Zaragoza and the company GeoSpatiumLab, S.L.

Exploring the Advances in Semantic Search Engines

Tuesday, September 14th, 2010, Walter Rentería Agualimpia

CEDI’10 was held in the last september in Valencia, Spain.

Walter Renteria-Agualimpia, Francisco J. López-Pellicer, Pedro R. Muro-Medrano, Javier Nogueras-Iso, and F.Javier Zarazaga-Soria, Exploring the Advances in Semantic Search Engines

We presented the paper in the last International Symposium on Distributed Computing and Artificial Intelligence DCAI’10. It is an annual forum that will bring together ideas, projects, lessons, etc.. associated with distributed computing, artificial intelligence and its applications in different themes.

Our work was focused on Semantic Search Engines.
With the vertiginous volume information growing, the amount of an-swers provided by traditional search engines and satisfying syntactically the user queries has enlarged directly. In order to reduce this problem the race to develop Semantic Search Engines (SSE) is increasingly popular. Currently, there are mul-tiple proposals for Semantic Search Engines, and they are using a wide range of methods for matching the semantics behind user queries and the indexed collec-tion of resources. In this work we survey the semantic search engines domain, and present a miscellaneous of perspectives about the different classification of ap-proaches. We have created a comparative scheme and identified the prevalent re-search directions in SSE.

The completed survey can be reviewed at the link:

The paper is published on Distributed Computing and Artificial – Series: Advances in Intelligent and Soft Computing, Vol. 79
