The aim of this paper is to solve the problem of disambiguation of authors’ names in scientific papers. In particular, it focuses on the problem of synonyms and homonyms. Thus, we often find two or more names written in different forms denoting the same person. Moreover, there may be several authors using the same name. To address both the synonym...
La falta de precisión y exhaustividad en los resultados obtenidos al realizar una búsqueda de información es un fenómeno que ocurre con mucha frecuencia. El desarrollo de servicios más efectivos propicia el logro de mejores resultados en las búsquedas de información. Una de las posibilidades que brinda la Web 3.0 son las ontologías y con ellas el s...
The linked data principles provide an efficient way to interlink resources across several datasets, improving interoperability and discoverability. Several digital libraries around the world are publishing their legacy data from catalogs and authority files following the linked data principles. However, selecting the most suitable datasets for crea...
Objective Theoretical procedures are proposed in indexing, and at the same time being introduced in plots of Computer Science to solve problems of the ICT Network of the VLIR Project from a multidisciplinary perspective, given the characteristics they impose the challenge of trying to develop any normative process in the field of indexing for a com...
Libraries and documentation centers haven’t a methodology guide to transform their RDF data into knowledge graphs, which prevents them from taking advantage of the facilities of this tool in the search and retrieval of information. This methodology was proposed for the transformation of bibliographic data in knowledge graphs. ANCORP was presented f...
The weighted completeness metrics for metadata use a weighting factor to indicate the importance of each field. In the case of bibliographic metadata, a common way of representing the importance of a field is its frequency of appearance in a given repository. The inaccuracy of this method is why we need to recalculate the weights as the volume of t...
Systems for traffic events administration are important tools in the prediction of disasters and management of that of the movement flow in diverse contexts. These systems are generally developed on non-fuzzy grouping algorithms and ontologies. However, the results of the implementation do not always give high precision scores due to different fact...
Several ontologies have been developed for the detection of failures in electric power systems. However, these ontologies have been developed for specific aspects of the electricity grid and do not consider the necessary elements for the representation of a fault detection system based on Smart Grid trends. In this paper, we describe the developmen...
El audiovisual como documento tiene características que lo diferencian del resto de las fuentes. Las actividades correspondientes al tratamiento de la información audiovisual se corresponden con una serie de etapas que pueden ser descritas a partir de un ciclo de vida. La ceración de un ciclo constituye un modelo de trabajo en centros donde se prod...

Publishing data as Linked Data increases the interoperability and discoverability of resources over the web space. This process involves several design decisions and technologies. However, there is no one-size-fits-all formula for publishing data as Linked Data. Also, the quality of linked data published is a key issue to take into account. In the...
In 2015 libraries from five Cuban universities supported by an international project sponsored by the Flemish Interuniversity Council (VLIR), started the development of digital libraries using Dspace to manage all the scientific and academic outputs stored in their collections with the aim to socialize, preserve and increase the visibility of the s...
Purpose
Information from CRIS is stored in different formats, in platforms that are not compatible, or even in independent networks. It would be helpful to have a well-defined methodology to allow for management data processing from a single site, so as to take advantage of the capacity to link disperse data found in different systems, platforms,...
SQL and, more recently, SPARQL are standard languages of the software industry for retrieving data. Other studies showed that retrieving data by using a SPARQL query is much slower than the semantically equivalent SQL query. Nevertheless, some recent proposals optimized database servers for SPARQL queries. This paper presents the results of a compa...
An ontology is a useful tool to deal with the heterogeneity of data and their semantization, with a view to raising the quality of processes of organization, search and retrieval of information in institutional management systems, particularly those implemented in a university web. In view of the wealth of multidisciplinary knowledge treasured by t...
The absence of a linked data model in the context of the Virtual Health Library of Cuba (VHL) causes deficiencies in the semantic interoperability of content and information retrieval. In addition, as added problem, the documentary component entities have different levels of bibliographic description and subject scope. This article proposes the des...
INTRODUCCIÓN: Los Repositorios Digitales han demostrado ser una herramienta muy útil para la socialización de la información científica, constituyendo la denominada ruta verde dentro del acceso abierto.
OBJETIVO: En el presente trabajo se recogen las principales características y funcionalidades de Dspace@UCLV, el primero de varios repositorios dig...
En este trabajo se presentan las principales tecnologías de la Web Semántica que pueden ser de utilidad para la gestión de fondos archivísticos. Se examinan diversos proyectos de ámbito internacional y local que parten de descripciones normalizadas ISAD-G para generar ontologías, así como la disponibilidad de LIAM (Linked Archival Metadata), que fa...

Authority control is recognized as an expensive task in the cataloging process. This is actually an active research field in libraries and related research institutions even when several approaches have been proposed in this research area. In this paper, we propose AUCTORITAS, a tool for exposing high value services on the web for the authority con...
La ambigüedad en el nombre de los autores en las revistas científicas es un problema que afecta a las publicaciones de este tipo. Dicho problema se refiere a la posibilidad de representar el nombre de los autores de diferentes formas en los metadatos bibliográficos presentes en los repositorios digitales. Este se puede manifestar de dos formas dife...
Resumen El Control de Autoridades, en el caso de los nombres de los autores, se refiere a la generación de formá unica de los mismos acorde a reglas previamente definidas. Esta es la parte más costosa del proceso de catalogación llevado a cabo por las instituciones bibliotecarias. Debido a la cantidad de información necesaria para llevar a cabo efi...

Using the database of the PuertoTerm project, an indexing system based on the cognitive model of Brigitte Enders was built. By analyzing the cognitive strategies of three abstractors, we built an automat that serves to simulate human indexing processes. The automat allows the texts integrated in the system to be assessed, evaluated and grouped by m...
