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.

Detecting Similar Areas of Knowledge Using Semantic and Data Mining Technologies
(ELSEVIER B.V., 2016-12-09) Sumba, X; Baculima Cumbe, John Fernando; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo; Sumba, F; Tello Guerrero, Marco Andrés
Searching for scientific publications online is an essential task for researchers working on a certain topic. However, the extremely large amount of scientific publications found in the web turns the process of finding a publication into a very difficult task whereas, locating peers interested in collaborating on a specific topic or reviewing literature is even more challenging. In this paper, we propose a novel architecture to join multiple bibliographic sources, with the aim of identifying common research areas and potential collaboration networks, through a combination of ontologies, vocabularies, and Linked Data technologies for enriching a base data model. Furthermore, we implement a prototype to provide a centralized repository with bibliographic sources and to find similar knowledge areas using data mining techniques in the domain of Ecuadorian researchers community.
Diseño e implementación de un repositorio ecuatoriano de datos enlazados geoespaciales

This work presents the processes and activities done for generation, publication and visualization of Geospatial Linked Data of Ecuador, considering that the Web advance (in both, Europe and North America) is focused on publication of this data types and let it to be structured and interconnected, to and from, different sources. Therefore, to generate Geospatial Linked Data, proceeded with the execution of every step of Linked Data's publication methodology. However, there were some troubles for this activity since semantic technologies knowledge is required to implement the generation process. Then, this work describes one solution to allow an easy Geospatial Linked Data generation, for which with a Web search, began a manual recollection of data that contains Geospatial information; after, proceeded with the development of new tools and the modification of the old ones for helping the Geospatial Linked Data generation and adding compatibility of new format of information; and finally, with the use of the developed and modified tools, implement and publish the prototype of the Ecuadorian's Geospatial Linked Data repository.
Similarity detection among academic contents through semantic technologies and text mining
(University of Informatics Sciences, 2018) Saquicela Galarza, Víctor Hugo; Baculima Cumbe, John Fernando; Orellana Flores, Gerardo Enrique; Baculima Piedra, Nelson Xavier; Orellana Campoverde, Marcos Eugenio
Abstract View references (46) Nowadays, the information of university courses is managed by means of syllabus based systems, this is the case of Ecuadorian Higher Education Institutions (IES for its Spanish acronym). However, the syllabus structure is not normalized among all universities, since there is a wide variety of formats and data models used for each IES which naturally, affects academic processes such as the students mobility or credits validation between IES. We have addressed these issues by presenting a proposal based on semantic technologies and text mining methods whose goal is to identify similarities among academic contents. © 2018 CEUR-WS.

Una ontología para representar la información geográfica en el dominio hídrico ecuatoriano
(IDICT, 2018-06-27) Lupercio Novillo, Rosa Lucía; Espinoza Mejía, Jorge Mauricio; Baculima Cumbe, John Fernando; Saquicela Galarza, Víctor Hugo; Lupercio Novillo, Rosa Lucía
In spite of the existing efforts for the creation of semantic models that ensure the interoperability in the water domain, the greater part of these proposals focus on solve specific needs, especially regarding the regulations that the geographic information has to fulfil in a territory or community. To tackle this need, in this work we propose the creation of an ontology that describes the basic concepts, based on existing semantic models of the community and that incorporate the representation of water resources applied to the Ecuadorian context considering the existing regulations. The data set instantiated in the ontological model come from of different Ecuadorian institutions. The modeling result is an ontological network conformed by a collection of ontologies joined through relations between them. All the process involved i) the selection and execution of activities proposed by the methodology NeOn for the construction of the ontology model, ii) the implementation using the Web Ontology Language (OWL), and iii) the documentation of the ontological model. We conclude that the created ontology, named hydrOntologyEC provides amore flexible platform to facilitate the interoperability of the agencies involved in the water domain.
