Towards an E-learning Platform Based on Interactive Visual Elements
(IEEE Computer Society, 2019) Medina Cartuche, Jose Luis; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo; Vega Zamora, Oswaldo Francisco
The traditional approach of e-learning platforms based on learning management systems has allowed education to be accessible to a broader group of people; however, their pedagogical model based on promoting a transmissive approach has caused learning outcomes do not achieve the success of their traditional counterpart. There is a disconnection between what happens in the physical classroom and what happens when students take an online class. The experience usually goes from interactive to static.In this work, we propose the design of an interactive e-learning platform that makes use of dynamic media such as videos, to improve the interactive experience of students. To this end, the main limitations of current systems are studied and different solutions are proposed to mitigate the problems. The main contributions of this work are, first, to establish a set of challenges that interactive e-learning platforms should support, and second, the description of the necessary processes to implement the platform.
Audio fingerprint parameterization for multimedia advertising identification
(Institute of Electrical and Electronics Engineers Inc., 2017) Medina Cartuche, Jose Luis; Vega Zamora, Oswaldo Francisco; Mendoza Siguenza, Daniel Emilio; Saquicela Galarza, Víctor Hugo; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Victor Hugo
This article follows step by step a general framework for fingerprint extraction in order to develop a system for advertisements' monitoring. The parameterization process uses some spatial and spectral characteristics measured over 600 advertisements that contain various types of sounds. Key factors such as accuracy, process time, and granularity are analyzed together in order to enhance the system performance. At the end, the algorithm shows an accuracy of 99% using three seconds of granularity samples, and also the best compromise between processing time and performance is achieved. This study suggests a set of parameterization steps which could be successfully implemented in other related audio applications. © 2017 IEEE.
Enriching Electronic Program Guides using semantic technologies and external resources
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2014-09-15) Saquicela Galarza, Víctor Hugo; Alban Bermeo, Humberto Marcelo; Espinoza Mejía, Jorge Mauricio; Palacio Baus, Kenneth Samuel
Electronic Program Guides (EPGs) describe broadcast programming information provided by TV stations. However, users may obtain more information when these guides have been enriched. The main contribution of this work is to present an automation process for EPG's information enrichment through the use of semantic technologies and external resources. Among the several resources involved in the enrichment process, the following can be mentioned : ontologies, web services, semantic repositories and natural language processing techniques.
REDI: a linked data-powered research networking platform
(Springer, 2018) Sumba Toral, Francisco Xavier; Segarra Flores, José Luis; Villazón Terrazas, Boris Marcelo; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo; Sumba Toral, Francisco Xavier
Research networking is a difficult part of academics in spite of the multiple benefits that the Web has brought within this field in recent years. Even though scientific and business social networks provide a medium to discover peers worldwide, their usefulness meets its limits when real-world requirements come in. The broad audience of those tools and other bibliographic databases lead them to ignore cultural and geographical aspects such regional indexes, organizational structures, among others. On this poster, we introduce REDI, a Linked Data - powered research networking platform which combines both local (institutional/regional) and external (Web) scholarly sources in a consolidated knowledge base. Moreover, REDI leverages on its knowledge base to cluster authors within similar research areas easing networking and unveiling a variety of new information from data for multiple purposes.
Mobile teleradiology system suitable for m-health services supporting content and semantic based image retrieval on a grid infrastructure
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2016-08-16) La Cruz Puente Alexandra; Espinoza Mejía, Jorge Mauricio; Medina Molina, Ruben; Pérez Rocano, Wilson Rodrigo; Saquicela Galarza, Víctor Hugo; Solano Quinde, Lizandro Damián; Vega, F; Vidal, M.-E
Teleradiology systems tackle the problem of transferring radiological images between medical image workstations for facilitating different medical activities, e.g., diagnosis, treatment and follow up a patient, medical training, or consulting second opinion. Nowadays, m-Health (aka mobile health) is becoming popular because of high quality of mobile displays, although remains a work in progress. In this paper a mobile teleradiology system is reported, which main contribution is the development of a platform: (1) supported by a Grid infrastructure, (2) using biomedical ontologies for adding semantic annotations on medical images, and (3) supporting semantic and content-based image retrieval. Images are located physically in different repositories like; hospitals and diagnostic imaging centers. All these features make the system ubiquitous, portable, and suitable for m-Health services.
Challenges and trends about smart big geospatial data: a position paper
(Institute of Electrical and Electronics Engineers Inc., 2018) Saquicela Galarza, Víctor Hugo; Vilches Blázquez, Luis Manuel; Tello Guerrero, Marco Andres
Currently, we are witnessing an exponential growth in the amount of data being generated and captured at multiple locations. This trend will continue over the next years. Hence, we have envisioned a scenario in which many objects will be referencing to or generating location information. Thus, the need for appropriately managing geospatial data is evident. In this paper, we present our vision for an integral Geo Linked Data platform; pointing out the current limitations and challenges in the GeoRDFization, Storage, Query Federation, and Visualization of data with an inherent spatial context.
Author-topic classification based on semantic knowledge
(Springer Verlag, 2019) Segarra Flores, José Luis; Sumba Toral, Francisco Xavier; Ortiz Vivar, Jose Enrique; Gualan Saavedra, Ronald Marcelo; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo
We propose a novel unsupervised two-phased classification model leveraging from semantic web technologies for discovering common research fields between researchers based on information available from a bibliographic repository and external resources. The first phase performs coarse-grained classification by knowledge disciplines using as reference the disciplines defined in the UNESCO thesaurus. The second phase provides a fine-grained classification by means of a clustering approach combined with external resources. The methodology was applied to the REDI (Semantic Repository of Ecuadorian researchers) project, with remarkable results and thus proving a valuable tool to one of the main REDI’s goals discover Ecuadorian authors sharing research interests to foster collaborative research efforts.
Annotating OGC web feature services automatically for generating geospatial knowledge graphs
(2021) Saquicela Galarza, Víctor Hugo; Freire Zurita, Renan Gonzalo; Corcho, Oscar; Vilches Blázquez, Luis M.
The spatial data infrastructure initiatives are now broadly developed and deployed. However, while plenty of tools use them, some tasks are still complex to perform by non-expert users, such as finding, accessing, and using some of their related OGC Web Services (OWS). One of the main reasons for these challenges is associated with semantic heterogeneity within these services. This entails a lack of proper descriptions and requires knowledge about data structure and domain-specific query languages to discover and retrieve these services. Semantic annotations of OWS play a crucial role in achieving semantic interoperability and addressing these associated challenges. In this article we describe an approach for enabling the automatic generation of semantic annotations of Web Feature Services (WFS) at their three request levels (GetCapabilities, DescribeFeatureType, and GetFeature), which are used to generate knowledge graphs. This approach uses various external services, ontological resources (POSM, DBpedia, GeoSPARQL, GeoNames, and datos.ign.es vocabularies), and knowledge bases (DBpedia and datos.ign.es). Moreover, this approach enables us to validate annotations obtained as a previous step to generating geospatial knowledge graphs. Additionally, we present our proposal through an application case and assess it using a representative set of 21 WFS services, achieving an average of 46.70% annotations, of which 22.29% and 35.52% were validated using DBpedia and datos.ign.es initiatives, respectively. This shows the feasibility of our approach to generate knowledge graphs from WFS services in an automatic way
A Systematic Literature Review on Composition of Microservices through the Use of Semantic Annotations: Solutions and Techniques
(Institute of Electrical and Electronics Engineers Inc., 2019) Chavez Zambrano, Kevin Eduardo; Cedillo Orellana, Irene Priscila; Espinoza Mejía, Jorge Mauricio; Saquicela Galarza, Víctor Hugo
The aim of semantic web is to provide meaning to data shared by a network, therefore making it readable by humans and computer applications. The objective of this is to give the information and services a well-defined meaning by tagging web content with machine processable descriptions. Within the semantic web there are annotations, which relate data and classes offering a structured data. In addition, an ontology is an essential part of the semantic web, because it provides a vocabulary of terms and includes properties between concepts. There are several proposals over semantic annotations included in primary studies, but it is necessary to condense them in a secondary study, hence this paper presents a systematic literature review about the composition of microservices through the use of semantic annotations. This allows developers to determine which techniques are the most used in the semantic web. In order to perform this secondary study, the Kitchenham's methodology was applied. After its application, 68 articles were firstly obtained, once the inclusion and exclusion criteria was applied, only 39 studies were selected, which include automatic and manual review.
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.
