Currently, students' mobility in Higher Education has become very common and frequent. Although the transitioning process could be thought to be smooth and quick, students moving from one institution to another must go through rigorous and unfortunately, non-standardized academic validation processes. Usually, most part of the process, including credits recognition and syllabi comparison are manually performed, consuming excessive time and massive human effort. Some of these academic processes however, could be optimized by means of computer technologies, which support data processing and help solving real-life problems usually found in the academic field. In the specific case of Ecuador, we have identified that each Higher Education Institution (HEI) manages customized curricular information management systems which include non-standard syllabi structured documents. The existence of custom made formats at every HEI has originate a large variety of data models. In this work, we propose to address these problems by identifying similarities between different current syllabi of Ecuadorian HEIs, aiming to the optimization, integration and improvement of the academic activities related to the students' mobility processes, such as credits recognition. This proposal relies on the definition of a standard data model, which is used to describe the academic syllabus and that allows the implementation of a computer-based system focused on similarities detection through the use of semantic web technologies and text mining tools.

Una aproximación basada en Linked Data para la detección de potenciales redes de colaboración científica a partir de la anotación semántica de producción científica: Piloto aplicado con producción científica de investigadores ecuatorianos

In this paper, a framework based on semantic Web technologies is presented to detect potential collaboration networks. The collaborators are identified through a semantic enrichment of scientific articles produced by researchers who publish with Ecuadorian affiliations. The scope of this work includes the papers, which have at least one author with Ecuadorian membership. Detected collaborative networks are an important basis to promote the efforts of the Ecuadorian government and higher education institutions, in order to prioritize the efforts and the resources invested in research and determine the relevance and coherence of the research programs.
Una aproximación para la descripción semántica de requisitos para categorización docentes de investigadores Ecuatorianos

The new generation of the Web, the Semantic Web, poses potential opportunities to give meaning to web content. In this paper a framework is presented for ontology network to represent concepts, attributes, operations and restrictions related to curricular items used in national categorization processes of Ecuadorian university teachers. The first part of the paper describes the domain context and related work, the following the abstraction of the model is described, and finally ontology is presented. The domain ontology provides the concepts meaning and their relationships within the domain of curricular items produced by academics, which are requirements of university teaching categorization process in Ecuador.
