A two LOM aplication profiles: for learning objects and for information objetcs

Learning Objects are the central concept of the current paradigm of E-Learning, but curiously, there is still a widespread confusion about how much to include, how big should be, or what is the “correct” granularity for a Learning Object. Because of this, different works use the same term to different things. This paper attempts to differentiate the concepts of Learning Objects and Information Objects, and analyze the potential for achieving adaptivity in the two levels. Particularly, studying the design of two LOM application profiles for exploit the specifics of each level of granularity.Presentado en el VIII Workshop Tecnología Informática aplicada en Educación (WTIAE)Red de Universidades con Carreras en Informática (RedUNCI

Ontology design for web sites recommendation in the health area

The query of web contents about the health area is an increasingcommon practice among users with different features. Some of them realize queries with a concrete aim, for example patients that suffer a disease or relatives of the patient, doctors, all of them demanding specific information about a disease. Others do it just by curiosity, for example to inform themselves about prevention of diseases. These users have different levels of academic training. Taken this fact into account, this paper presents the design of an ontology that aims to ease the task of determining the degree of adequacy that a given heath web site has for a given user, obtaining a recommendation of reading of the content for this user

Unifying multilevel modelling through ontologies

In the last decades, the multilevel problem has received increasing attention in the conceptual modelling and semantic web communities. Recently, we proposed a solution to this problem in the context of ontological modelling which consists in extending the Web Ontology Language OWL with a new multilevel constructor that equates instances to classes. In this work we highlight the advantages of exploiting the reasoning capabilities of OWL ontologies with the proposed multilevel constructor by analizing requirements from a real-world application on the accounting domain

Web Site Recommendation Modelling Assisted by Ontologies Networks

Web site recommendation systems help to get high quality information. The modeling of recommendation system involves the combination of many features:metrics of quality, quality criteria, recommendation criteria, user profile, specific domain, among others. At the moment of the specification of a recommendation system it must be guaranteed a right interrelation of all of this features. In this paper we propose a ontology network based process for web site recommendation modeling. This ontology network conceptualizes the different domains (web site domain, quality assurance domain, user context domain, recommendation criteria domain, specific domain) in a set of interrelated ontologies. Basically, this work introduces the semantic relationships that were used to construct this ontology network. Moreover, it shows the usefulness of this ontology network for the detection of possible inconsistencies when specifying recommendation criteria. Particularly, this approach is illustrated for the health domain

Ontology-based process for recommending health websites

Website content quality is particularly relevant in the health domain. A common user needs to retrieve health information that is precise, reliable and relevant to his/her profile. Website recommendation systems are an aid to get high quality health-related web sites according to the user's needs. However, in practice, it is not always evident how to describe recommendation criteria for health website. The goal of this paper is to describe, by an ontology network, the criteria used by a health website recommendation process. This ontology network conceptualizes the different domains that are involved in the Salus Recommendation Project as a set of interrelated ontologies.Publicado en IFIP Advances in Information and Communication Technology book series (IFIPAICT, vol. 341).Laboratorio de Investigación y Formación en Informática Avanzad

A Novel Method for Curating Quanti-Qualitative Content

This paper proposes a Researcher-in-the-Loop (RITL) guided content curation approach for quanti-qualitative research methods that uses a version control system based on consensus. The paper introduces a workflow for quanti-qualitative research processes that produces and consumes content versions through collaborative phases validated through consensus protocols performed by research teams. We argue that content versioning is a critical component that supports the research process's reproducibility, traceability, and rationale. We propose a curation framework that provides methods, protocols, and tools for supporting the RITL approach to managing the content produced by quanti-qualitative methods. The paper reports a validation experiment using a use case about the study on disseminating political statements in graffiti

Applying ontologies to educational resources retrieval driven by cultural aspects

This work presents the architecture used in the ongoing e-learning EduCa Project. The approach is based in a strong use of ontologies for the retrieval, management and clustered of electronic educational resources according to user's cultural aspects. Cultural aspects are preferences and ways of behavior determined by the person's culture. In this project, the cultural aspects are just the features that distinguish between the preferences of users from different regions.Facultad de Informátic

Análisis de herramientas CASE para uso didáctico en diseño de bases de datos

En este trabajo se plantea un marco evaluatorio que resume las características elementales que debería presentar una herramienta CASE para el apoyo a los cursos de Bases de Datos, contemplando aspectos técnicos y didácticos. Se realiza una evaluación de herramientas CASE existentes relevadas y se plantea cuán lejos se está de satisfacer el ideal planteado y posibles alternativas para lograrlo.Eje: Tecnología aplicada en EducaciónRed de Universidades con Carreras en Informática (RedUNCI
