- A probabilistic BPMN normal form to model and advise human activities(Springer Verlag, 2015-05-05) Flores Solorio, Victor; Garcia, Juan Pablo; Ceballos Cansino, Héctor Gibrán; Tecnológico de MonterreyAgent-based technologies, originally proposed with the aim of assisting human activities, have been recently adopted in industry for automating business processes. Business Process Model and Notation (BPMN) is a standard notation for modeling business processes, that provides a rich graphical representation that can be used for common understanding of processes but also for automation purposes.We propose a normal form of Business Process Diagrams based on Activity Theory that can be transformed to a Causal Bayesian Network, which in turn can be used to model the behavior of activity participants and assess human decision through user agents. We illustrate our approach on an Elderly health care scenario obtained from an actual contextual study.
- An alignment comparator for entity resolution with multi-valued attributes(Springer Verlag, 2014-11-22) Mazzucchi-Augel, Pablo N; Ceballos Cancino, Héctor GibránEntity matching is a problem that concerns many data management processes. If we consider matching between entities represented by RDF individuals we might find attributes values lists with variable-length for some properties, which will lead us to the problem of comparing multi-valued attributes, e.g. comparing author names lists for determining publication matching. This matching technique would be more complex than comparing fixed-length records, but less complex than comparing XML documents. Instead of comparing a single string, representing the concatenation of these values, each value of one vector should be compared against all values of the other vector. We propose a set of heuristics to address the alignment and comparison process of multi-valued attributes and evaluate them in the context of bibliographic databases. Our first results show that it is possible to reduce the comparisons amount and provide an aggregated similarity metric that outperforms the average similarity of cross product comparisons.
- Using activity theory and causal diagrams for designing multiagent systems that assist human activities(Springer Verlag, 2013-11-30) Brena, Ramon; Ceballos Cansino, Héctor Gibrán; García Vázquez, Juan Pablo; Instituto Tecnológico y de Estudios Superiores de MonterreyIn this paper, we propose to use the Activity Theory and causal diagrams for modelling human activities with the aim of facilitating the specification of an agent-based assistance system through the Prometheus methodology. As a case study, we consider the elder medication activity, a recurring, complex and context-rich activity that involves several individual and collective activities which may require assistance. From the data collected in a contextual study of the elder medication, we modeled the medical consultation and refill medicine activities. Our results demonstrate that causal diagrams allow to capture the dynamics of the modelled activity, introduce the assistance of intelligent agents, extract the multiple scenarios synthesized in the activity structure and translate them into Prometheus artifacts.
- Finding compromises between local and global ontology querying in multiagent systems(Springer Verlag, 2004) Ceballos, Hector; Brena, Ramon; Instituto Tecnológico y de Estudios Superiores de MonterreyAs Ontologie knowledge gets more and more important in agent-based systems, its handling becomes crucial for successful applications. In the context of agent-based 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. In this sort of "caching" scheme, most frequent ontologie queries tend to remain stored locally. 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, and discuss some performance figures.
