Semantic sense extraction from Wikipedia pages
2010
This paper presents a technique aimed to extract structured information from unstructured Wikipedia contents related to a particular topic, and to arrange it in a semantic way inside an ontology. The general framework is the design of an artificial agent able to deliberate when increasing its domain knowledge. In particular, this cognitive agent acts as a dialogue manager in an Intelligent Tutoring System (ITS) already presented by the authors. Our approach is based on the definition of useful patterns able to extract and identify novel concepts and relations to be added to the knowledge base. We propose a method that uses information from the wiki page’s structure. We define different stra…
Knowledge-Based Systems and F.E. Simulations in Metal-Forming Processes Design An integrated Approach
1991
Summary The automatic computer aided planning and design of cold forming processes includes several phases, among which the most important are the optimal choice of the forming operations sequence and, for each operation, the determination of the more suitable operating parameters. With this aim the Authors propose an integrated approach based on the preliminary choice of some feasible forming sequences, carried out by means of a knowledge-based system, and on the subsequent determination of the optimal one employing a finite element simulation of the process.
Time Markers for the Evolution and Exhumation History of a Late Palaeozoic Paired Metamorphic Belt in North-Central Chile (34°-35°30'S)
2005
A multi-method geochronological approach is applied to unravel the dynamics of a paired metamorphic belt in the Coastal Cordillera of central Chile. This is represented by high-pressure - low-temperature rocks of an accretionary prism (Western Series), and a low-pressure- high-temperature overprint in the retro-wedge with less deformed metagreywackes (Eastern Series) intruded by magmas of the coeval arc. A pervasive transposition foliation formed in metagreywackes and interlayered oceanic crust of the Western Series during basal accretion near metamorphic peak conditions (∼350-400°C, 7-11 kbar) at 292-319 Ma (
Acquisition of competencies with serious games in the accounting field: an empirical analysis
2018
El actual sistema de educación superior se basa en un aprendizaje activo por parte del estudiante enfocado al desarrollo de competencias genéricas y específicas. En este contexto muchos autores defienden el uso de simulaciones que favorezcan dicho aprendizaje y, los denominados «juegos serios» (serious games [SG]) se adaptan a este reto. Sin embargo, el empuje que cabría esperar por el desarrollo de las nuevas tecnologías y de la llegada de los denominados «nativos digitales» a las aulas no es coherente ni con su grado de implantación ni con la escasa investigación desarrollada sobre la efectividad de su uso. Los objetivos de este estudio son describir una experiencia docente de implantació…
Action-oriented classification of families' information and communication actions: exploring mothers' viewpoints
2009
Action-oriented service and technology development begins with the idea that people use technologies to reach their action goals. Consequently, we should investigate user needs and how they can be satisfied, and adapt services and technologies to the natural course of actions. Here, we focus on family communication and investigate mobile communication service types for families. For this study 10 mothers were interviewed; we investigated the nature of their everyday information and communication needs and the different knowledge and information transfer actions that were discovered in their families. Qualitative analysis of these interviews was used to generate a taxonomy, which, in turn, c…
Process reference frameworks as institutional arrangements for digital service innovation
2020
Abstract Information systems (IS) service organizations are increasingly more concerned with their ability to co-create digital services with customers in service ecosystems. Practitioners and researchers, however, lack understanding of which organization mechanisms effectively contribute to IS organizations’ innovation practices. Grounded in service-dominant logic, we hypothesized that process reference frameworks (PRFs), such as the IT Infrastructure Library (ITIL), act as institutional arrangements through their norms, rules, and practices, enhancing IS organizations’ ability to innovate digital services. Data collected from 159 IS organizations confirmed our hypotheses, showing that eff…
Leveraging Collaborative Governance: How Co-production Contributes to Outcomes and Public Value in a Small Town
2020
Collaborative governance is increasingly considered an effective approach to improve outcomes and public value. This chapter focuses on co-production as an instrument to implement collaborative governance at local level. It is not uncommon that small towns develop co-production processes to deliver cultural and touristic services. Out of a literature review, the study develops a Dynamic Multidimensional Performance Management framework to explore the impact of co-production on community outcomes. To this end, this chapter discusses the case “Museo Civico di Castelbuono (MCC)”,which concerns the co-production process of the guided tour of the museum’s venue. The resulting model provides insi…
A SOA-based health service platform in smart home environment
2011
The increasing demand for a good healthcare quality has brought Information and Communication Technology to an important role in healthcare domain. The trend in decreasing number of formal healthcare workers gives further pressure to move non-urgent treatments to the patients' homes. However, delivering healthcare services to meet the changing needs of inhabitants in a smart home requires an open and flexible service creation and integration environment so that the modification of existing services as well as creation of new services can be achieved in a timely manner. This paper presents a vision of a logical integration platform in a smart home environment, integrating various devices and…
Gaining Competitive Advantage through Standardization and Differentiation of Services
2015
The goal of the paper is to study the question of whether or not differences between cultural groups influence the decision of a consumer wishing to avail himself of a particular service. Therefore we have developed a semiotic extension of the means-end approach as the theoretical basis for elaborating a solution to this problem. The conjoint analysis specifies the results of the meansend analysis.
Consumer Information Systems as Services
2017
Consumer Information Systems (CIS) are a type of information systems that provides services to consumers instead of addressing users in traditional organizational settings, such as Internet based television. Services typically involve a trade-off between achieving high service productivity and quality. The use of service mass customization to successfully address these issues of both productivity and quality in a service context is proposed. We suggest that the development of Consumer Information Systems as Services (CISaS) may achieve such service mass customization. This paper presents a conceptual framework and investigates how it applies to a set of Internet Protocol Television (IPTV) o…
