I obtained a PhD in Library Science from the Carlos III University in 1999 on the subject of Knowledge Information Systems and its relationships with linguistics. From 1991-1999, I had grants and contracts from the Spanish National Research Council.My current research activity is centered on text mining, information extraction and pattern recognition, NLP, information retrieval, Web positioning, and Knowledge Organization Systems. I have published mainly on semi-automatic construction of thesauri and ontologies, topic maps, and conceptual and contextualized retrieval of semantic documents. My last projects deal with Semantic Metadata Interoperability and Search (SEMSE) and LIS training.I have taught courses on Information Retrieval, Search Engine Optimization, Software Engineering, and Knowledge Modelling Techniques and Management Systems. Some of them are published in the OpenCourseWare projectedit

In the present scenario, Automatic Text Summarization (ATS) is in great demand to address the ever-growing volume of text data available online to discover relevant information faster. In this research, the ATS methodology is proposed for the Hindi language using Real Coded Genetic Algorithm (RCGA) over the health corpus, available in the Kaggle dataset. The methodology comprises five phases: preprocessing, feature extraction, processing, sentence ranking, and summary generation. Rigorous experimentation on varied feature sets is performed where distinguishing features, namely- sentence similarity and named entity features are combined with others for computing the evaluation metrics. The top 14 feature combinations are evaluated through Recall-Oriented Understudy for Gisting Evaluation (ROUGE) measure. RCGA computes appropriate feature weights through strings of features, chromosomes selection, and reproduction operators: Simulating Binary Crossover and Polynomial Mutation. To extr...

New technologies require an upgrade of LIS professionals’ skills. This study analyzes changes in the field and suggests guidelines to improve LIS curriculum. We have carried out a content analysis of 20 curricula from LIS educational programs to identify terms associated with technological skills. In addition, we identified terms related to new competences from 735 job openings published on generic web sites and 170 on specific web sites. These terms include marketing, management, and content management, mainly related to web applications. The results confirm a positive trend in the demand for technological skills related to LIS. Nevertheless, there is a need to increase awareness about the competences and abilities of LIS professionals, because many relevant job openings are listed in other job categories. Therefore, we have collected a list of key technological skills. In conclusion, it is clear that computer science and the Internet are bringing new opportunities to LIS professio...

"La automatización del proceso de adquisición de conocimiento a partir de documentos textuales en formato electrónico conlleva múltiples dificultades. Una de esas dificultades es el tratamiento textual en si mismo por la diversidad de formatos o su ausencia. Así una metodología idónea deberá marcar bajo que pautas estos documentos serán tratados. Por otra parte, un procesamiento lingüístico potente es necesario para salvar estas dificultades. Se ha mostrado una metodología que está demostrando ser eficiente en distintos dominios y aplicaciones. La automatización completa por el momento no ha resultado factible. Existen en estudio múltiples aplicaciones a Vigilancia tecnológica y Reutilización de Software. Según los experimentos desarrollados, la metodología idónea debe estar basada en una clasificación facetada que facilite la reutilización e interoperabilidad de estos sistemas de sistemas de organización del conocimiento. Todas las experiencias ensayadas indican que las clasificaciones propuestas, tras la aplicación de las herramientas informáticas al análisis de un dominio, deberán ser valoradas y validadas por un experto. Por el momento una automatización totalmente ajena a la intervención humana no parece ser realista. Como futuro desarrollo se deberá resolver los problemas asociadas a la validación por los expertos en el dominio, ya que provoca demoras e inconsistencias en la obtención del dominio. En conclusión, las tareas asignadas a los expertos deberán ser breves y sencillas para que la metodología sea efectiva, o bien ser simplificadas mediante minería de datos."

ABSTRACT In this article we perform a qualitative analysis of well-known generic ontologies according to their retrieval potential in order to implement a conceptual retrieval system. This retrieval system aims to search metadata schemes. The main problem in the implementation of retrieval system has been finding a reference ontology covering the domain and matching the system's requirements. We performed an evaluation of ontologies' characteristics for their suitability to represent the semantic of specific metadata scheme. Finally, PROTON has been selected as ontology due to its extensibility, adaptability to the domain, adequacy to the retrieval system and its availability. The principal contribution of this study is the provision of guidelines towards the selection of ontologies to be mapped, based on qualitative analysis and experience.

The terminology used in Biomedicine shows lexical peculiarities that have required the elaboration of terminological resources and information retrieval systems with specific functionalities. The main characteristics are the high rates of synonymy and homonymy, due to phenomena such as the proliferation of polysemic acronyms and their interaction with common language. Information retrieval systems in the biomedical domain use techniques oriented to the treatment of these lexical peculiarities. In this paper we review some of the techniques used in this domain, such as the application of Natural Language Processing (BioNLP), the incorporation of lexical-semantic resources, and the application of Named Entity Recognition (BioNER). Finally, we present the evaluation methods adopted to assess the suitability of these techniques for retrieving biomedical resources.

Open source software is becoming more popular worldwide due to the quality of its products. Open source repositories are tools to access this kind of software, but when it comes to search any particular component, it is not easy to find what is required quickly. This paper studies the feasibility of using other sorting algorithms, in order to improve the results provided by open source software repositories; for this purpose the use of sorting algorithms based on graphs of relationships between open source software projects is analyzed. The results of four different sorting algorithms have been compared with the opinion of a group of experts in the domain area where the experiment was conducted. The results show that there are slight discrepancies between the ranking provided by the open source repository, sorting algorithms and expert opinion. These results underscore the possibility of including new sorting techniques in open source repositories in order to obtain better results i...

In this article we perform a comparison between two approaches to the modeling of the hierarchical structure of the real world: on the one hand, generic and whole-part relationships in a descriptors thesaurus; on the other hand, generalization and aggregation relationships in UML. Trying to shorten the distance between them leads to a new metamodel of relationships that can reflect better the mental habits of modelers when dealing with hierarchical trees.

Purpose – This paper seeks to analyze and evaluate different types of semantic web retrieval systems, with respect to their ability to manage and retrieve semantic documents. Design/methodology/approach – The authors provide a brief overview of knowledge modeling and semantic retrieval systems in order to identify their major problems. They classify a set of characteristics to evaluate the management of semantic documents. For doing the same the authors select 12 retrieval systems classified according to these features. The evaluation methodology followed in this work is the one that has been used in the Desmet project for the evaluation of qualitative characteristics. Findings – A review of the literature has shown deficiencies in the current state of the semantic web to cope with known problems. Additionally, the way semantic retrieval systems are implemented shows discrepancies in their implementation. The authors analyze the presence of a set of functionalities in different type...

This short paper describes our five submissions to the 2012 edition of the MIREX Symbolic Melodic Similarity task. All five submissions rely on a geometric model that represents melodies as spline curves in the pitch-time plane. The similarity between two melodies is then computed with a sequence alignment algorithm between sequences of spline spans: the more similar the shape of the curves, the more similar the melodies they represent. As in MIREX 2010 and 2011, our systems ranked first for all effectiveness measures used. However, this year there was only one competing system, so we employ this report mainly to describe and compare results within our systems.
