A Conceptual Probabilistic Model for the Induction of Image Semantics
2010
In this paper we propose a model based on a conceptual space automatically induced from data. The model is inspired to a well-founded robotics cognitive architecture which is organized in three computational areas: sub-conceptual, linguistic and conceptual. Images are objects in the sub-conceptual area, that become "knoxels" into the conceptual area. The application of the framework grants the automatic emerging of image semantics into the linguistic area. The core of the model is a conceptual space induced automatically from a set of annotated images that exploits and mixes different information concerning the set of images. Multiple low level features are extracted to represent images and…
The Conceptual Levels and Theory Languages of Interaction Design
2009
In a way, concepts are like friends. Tell me what your concepts are and I can tell what you are. Modifying freely the way Wittgenstein (1921) expressed this important Kantian (1781) point on the limiting power of concepts on one’s thinking, the concepts that human– technology interaction designers of different scientific backgrounds use differ from each other and, consequently, they are apt to solve the same tasks in different ways. Theoretical concepts constrain the kinds of questions specialists can ask and what kinds of things they are interested in. Thus programmers have a different view of users than do psychologists or sociologists. Just as a lay person can understand little about ven…
Incompleteness in Conceptual Data Modelling
2013
Although conceptual data modelers can ”get creative” when designing entities and relationships to meet business requirements, they are highly constrained by the business rules which determine the details of how the entities and relationships combine. Typically, there is a delay in realising which business rules might be relevant and a further delay in obtaining an authoritative statement of these rules. We identify circumstances under which viable database designs can be constructed from conceptual data models which are incomplete in the sense that they lack this “infrastructural” detail normally obtained from the business rules. As such detail becomes available, our approach allows the con…
The impact of local communities on the school development - a case study examining expectations and inclusion on a systemic level
2019
This paper presents one specific case of our school development research project. It shed light on the issue of a local community and the structure of expectations, which may limit the school’s development and students’ development. Because this project takes place in Scandinavia one needs first to understand the schooling policy called “one school for all”, which stresses inclusion. In addition, the phenomenon Langfeldt describes as “the quality of schools is created locally” will be explained, as well as the nature of expectations. The data collected is used to show the case’s limiting behavior, the balancing expectation structure between the school and the local community. Based on the c…
The Role of Education in Promoting Social Innovation Processes in the Society
2015
<em>The<strong> </strong>purpose of the paper<strong> </strong>is to</em> <em>clarify the role of education in promoting social innovation processes in the society based on the main findings of the theoretical study conducted from October 2014 to January 2015 within the project “Involvement of the Society in Social Innovation for Providing Sustainable Development of Latvia” supported by the National Research Program 5.2.</em><strong> </strong><em>EKOSOC-LV. The paper provides the analysis of causal interaction between social innovation and education, as well as two conceptual models which disclose the relationship between soc…
Coastal Sustainable Development Studies in Latvia: Integrated Local Social-Ecological Systems Governance
2021
Importance of sustainable coastal governance also in the Baltic sea region has been widely recognised and since such governance has to have integrative nature that requires horizontal cross-sectorial integration as well as involvement of all governance levels and subsequently organisation of vertical integration among the levels. Besides some succesfull local cases around Europe, mainly special outside projects based, there is to be recognized that the municipal integrated sustainable coastal governance has not been yet neither well and widely locally developed in practice nor sufficiently researched field in order to permit necessary design of adequate policy innovations. Practical develop…
Geometric and conceptual knowledge representation within a generative model of visual perception
1989
A representation scheme of knowledge at both the geometric and conceptual levels is offered which extends a generative theory of visual perception. According to this theory, the perception process proceeds through different scene representations at various levels of abstraction. The geometric domain is modeled following the CSG (constructive solid geometry) approach, taking advantage of the geometric modelling scheme proposed by A. Pentland, based on superquadrics as representation primitives. Recursive Boolean combinations and deformations are considered in order to enlarge the scope of the representation scheme and to allow for the construction of real-world scenes. In the conceptual doma…
A Models-to-Program Information Systems Engineering Method
2021
The Model-Driven Development paradigm aims to represent all the information system features through models. Conceptual-Model Programming offers a similar approach, but with a focus on automatic code generation. Both approaches consider modeling and traceability of different abstraction levels, where each level can be tackled with different modeling methods. This heterogeneity introduces a challenge for the quality of the traceability and transformations among models, especially when aiming for automatic code generation. In this paper, we introduce a holistic conceptual-model programming method to generate code from different abstraction levels (from the problem space to the solution space),…
The Effect of Negative Electronic Word of Mouth on Switching Intentions: A Social Interaction Utility Approach
2016
The aim of this chapter is to gain insight on negative eWom about brands from a sender perspective, taking into account individual and social factors. We develop and test a conceptual model using a sample of 302 Spanish active users of social networks who have complained online in 2013. This study provides several theoretical implications. Firstly, using the Social Interaction Utility framework, we analyse the influence of social motivations on negative eWom. Our results show that social motivations are the primary antecedents leading consumers to communicate their negative experiences to other consumers. Successful network sites should identify the effect of social motivations and manage t…
Human Simulation: A Transdisciplinary Approach to Studying Societal Problems
2019
In this chapter, we present a transdisciplinary framework where humanities scholars, social scientists, and engineers can work together to tackle large and complex societal problems. We identify the steps required to construct a human simulation model and the concerns and issues that must be addressed to ensure success. We also present some basic definitions and assumptions inherent to developing this sort of model.
