- The effect of similar surface features on students’ understanding of the interaction of charges with electric and magnetic fields(2020-01-15) Hernández, Eder; Campos, Esmeralda; Barniol, Pablo; Zavala, GenaroThe literature in student problem-solving abilities in PER has pointed out that novices tend to focus on the surface features of a problem, instead of the underlying principles. In Electricity and Magnetism (E&M) courses, students can confuse the concepts of electric and magnetic fields, which are often represented in problems with similar surface features. It is important to compare the students’ performance on these type of problems to evaluate their understanding of these topics. With this aim, we conducted a study to explore students’ performance in E&M open-ended problems presented with similar surface features. We applied two versions of a questionnaire, one with electricity and one with magnetism problems, to 322 introductory E&M students. In this study, we present some results focusing on a comparison between students’ understanding of electric and magnetic fields in questions regarding electric charges in uniform fields, both at rest and in motion.
- Recommending intra-institutional scientific collaboration through coauthorship network visualization(2013-10-28) Prada, Gustavo A; Cantu-Ortiz, Francisco J; Rodríguez-Acevez, Lucía Alejandra; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyFor improving research productivity, quality and dissemination, we propose the development of a visual recommendation tool summing up scientific collaboration best-practices found in literature. Social Network Analysis are applied to a coauthorship network for generating a Potential Collaboration Index (PCI) based on productivity, connectivity, similarity and expertise. This work is evaluated by recommending intra-institutional collaboration in a comprehensive university. The accuracy of PCI is documented, along with suggestions and comments from 27 interviewed researchers.
- Integrating semi-structured information using semantic technologies: An evaluation of tools and a case study on university rankings data(SciTePress, 2014-08-31) Casas-Bayona, Alejandra; Ceballos Cansino, Héctor GibránInformation integration is not a trivial activity. Information managers face problems like: heterogeneity (in data, schemas, syntax and platforms), distribution and duplicity. In this paper we: 1) analyze ontology-based methodologies that provide mediation frameworks for integrating and reconciling information from structured data sources, and 2) propose the use of available semantic technologies for replicating such functionality. Our aim is providing an agile method for integrating and reconciling information from semistructured data (spreadsheets) and determining to which extent available semantic technologies minimize the need of ontological expertise for information integration. We present our findings and lessons learned from a case study on university rankings data.
- Mapping relational databases through ontology matching: A case study on information migration(2011-10-24) Rodriguez-Mancha, Manuel; Cantu, Francisco J; Diaz-Prado, Aldo; Ceballos Cancino, Héctor GibránIn order to aid domain experts during data integration, several schema matching techniques have been proposed. Despite the facilities provided by these techniques, mappings between database schemas are still made manually. We propose a methodology for mapping two relational databases that uses ontology matching techniques and takes advantage of tools like D2R Server and AgreementMaker for automating mapping generation and for enabling unified access to information. We present the results obtained by some ontology matching algorithms in this context, demonstrating the feasibility of this approach.
- Emerging technologies for the proposal and design of a MOOC on social entrepreneurship.(2020-04-28) Ramírez-Montoya, María-Soledad; González-Padrón, José-Guadalupe; Muzquiz-Flores, Marlene; García-González, Abel; Romero-Rodríguez, José María; Aznar-Díaz, Inmaculada; Tecnologico de MonterreyEmerging technologies such as virtual reality and mixed reality are an educational resource that attracts students' attention and increases their interest in the content presented. The application of this technology to a MOOC course makes the proposal to motivate students really interesting. This paper presents the proposal and design of a MOOC course on social entrepreneurship that integrates virtual reality and open educational resources. Furthermore, the methodology used in the course is based on the Learning Environment Modeling Language (LEML). This makes it really attractive to the public, while improving the traditional content of a training course. Finally, the main findings and implications of the training course on competence in social entrepreneurship and its relation to the development of Sustainable Development Objectives are discussed.
- Validation of instruments to measure social entrepreneurship competence. The OpenSocialLab project(2020-04-28) García-González, Abel; Ramírez-Montoya, María-Soledad; Romero-Rodríguez, José María; Romero-Rodríguez, Luis Miguel; Tecnologico de MonterreyEducation within universities should consider the promotion of training activities aimed at training people who are creative, innovative, enterprising and aware of their environment and needs. The purpose of this paper is to present the preliminary results of the piloting of three instruments for a methodological proposal aimed at measuring the level of mastery scaled by students of undergraduate and graduate courses, in terms of social entrepreneurship skills. Thus, the instruments were validated through various strategies such as expert judgement, non-participating observation, statistical validity and reliability. Furthermore, the piloting takes place within the framework of a mixed method, since the data collection instruments were the focus group, the questionnaire and the semi-structured interview. The sample participating in the validation was different, depending on the instrument piloted: focus group (n = 5), questionnaire (n = 98) and interview (n = 4). Finally, the contributions of this work can be of value in studying social entrepreneurship.
- A hybrid local-global approach for handling ontologies in a multiagent system(2004-06-24) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyAs Ontologic knowledge gets more and more important in agent-based systems, its handling becomes crucial for successful applications. We propose a hybrid approach, in which part of the ontology is handled locally, using a "client component", and the rest of the ontological knowledge is handled by an "ontology agent", which is accessed by the other agents in the system through their client component. We propose specific methods for representing, storing, querying and translating ontologies for effective use in the context of the "JITIK" system, which is a multiagent system for knowledge and information distribution. We report as well a working prototype implementing our proposal.
- Combining global and local ontology handling in a multiagent system(IEEE Computer Society, 2004-05-19) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyOntologic knowledge is getting more and more important in agent-based systems, and its handling is becoming crucial for successful applications. But placing all the ontology-handling capabilities in each of the system's agents could make them too heavy. We propose a combination of local and global ontology handling, where part of the ontology is handled locally, using a "client component", and the rest of the ontological knowledge is handled by an "ontology agent", which is accessed by the other agents in the system through their client component. We propose specific methods for representing, storing, querying and translating ontologies for effective use in the context of the "JITIK" system, which is a multiagent system for knowledge and information distribution. We report a working prototype implementing our proposal.
- Modelling intelligent agents through causality theory(IEEE Computer Society, 2007-11-10) Cantu, Francisco J; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyWe introduce Causal Agents, a methodology and agent architecture for modeling intelligent agents based on Causality Theory. We draw upon concepts from classical philosophy about metaphysical causes of existing entities for defining agents in terms of their formal, material, efficient and final causes and use computational mechanisms from Bayesian causal models for designing causal agents. Agent's intentions, interactions and performance are governed by their final causes. A Semantic Bayesian Causal Model, which integrates a probabilistic causal model with a semantic layer, is used by agents for knowledge representation and inference. Agents are able to use semantic information from external stimuli (utterances, for example) which are mapped into the agent's causal model for reasoning about causal relationships with probabilistic methods. Our theory is being tested by an operational multiagents system implementation for managing research products.
- Towards a causal framework for intelligent agents development(2009-11-13) Cantu, Francisco J; Ceballos Cansino, Héctor Gibrán; Instituto Tecnológico y de Estudios Superiores de MonterreyIn this paper we present a Causal Artificial Intelligence Design (CAID) theory that borrows notions from Classical philosophy for modeling intelligent agents. Principles introduced by this theory are used for extending a goal-driven BDI architecture and implementing what we call Causal Agent. This architecture incorporates causal formalisms like Pearl's Do calculus and C+ which are adapted to Semantic Web knowledge representations. Our approach includes an ontological agent description that enables and justifies the instantiation of agents as part of a plan. An experimental prototype used for validating experimentally our approach is commented.
