Summary
This study introduces a dynamic user profile structure using Simple Knowledge Organization for the Web (SKOS) to enable interoperability between diverse user models. A two-tier matching strategy facilitates concept schema alignment for seamless data sharing in ubiquitous computing.
Area of Science:
- Computer Science
- Human-Computer Interaction
- Ubiquitous Computing
Background:
- User profile information is fragmented across various sources, hindering a comprehensive understanding of users.
- Existing user models lack interoperability due to syntactic and semantic heterogeneity.
- The ubiquitous user modeling community recognizes the need for sharing information from diverse user models.
Purpose of the Study:
- To address the heterogeneity of user models and enable user modeling interoperability.
- To propose a dynamic user profile structure for knowledge representation in ubiquitous user modeling.
- To develop a strategy for aligning concept schemas to facilitate data sharing.
Main Methods:
- Utilized Simple Knowledge Organization for the Web (SKOS) for dynamic user profile structure and knowledge representation.
- Proposed a two-tier matching strategy for concept schemas alignment.
- Demonstrated the proposal in an application scenario focused on sharing and reusing data for managing overweight and obesity.
Main Results:
- Successfully created a dynamic user profile structure based on SKOS for ubiquitous user modeling.
- Developed and validated a two-tier matching strategy for effective concept schema alignment.
- Showcased the practical application of the proposed interoperability solution in a health-related data sharing scenario.
Conclusions:
- The proposed SKOS-based dynamic user profile structure enhances knowledge representation for ubiquitous user modeling.
- The two-tier matching strategy effectively enables user modeling interoperability by aligning heterogeneous concept schemas.
- The approach facilitates the sharing and reuse of user data, with potential applications in health management and other domains.

01:30Social Foundations of Self IV: Self in Digital Communication
Since the early 2000s, computer-mediated communication (CMC) has grown rapidly, playing a crucial role in self-development. A key distinction between CMC and real-life interactions is the lack of a physically present partner. This absence makes non-verbal cues such as facial expressions, body language, and paralinguistic signals unavailable in CMC platforms like email, instant messaging, or social media. The lack of these cues can create ambiguity and complicate how feedback is interpreted.The...
02:16Stereotype Content Model
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...
01:26Social Exchange Theory
As formulated by John Thibaut and Harold Kelley, Social Exchange Theory explains human relationships as economic-like exchanges that maximize rewards and minimize costs. This theory suggests that individuals engage in relationships to gain benefits and reduce burdens, similar to economic transactions. It has been widely applied to various types of relationships, including romantic, professional, and social interactions.Rewards and Costs in RelationshipsRelationship rewards include emotional...
02:06Social Exchange Theory
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).
01:20Social Foundations of Self II: The Generalized Other
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
01:21Role-Based Identity
Role-based identities are central to understanding how individuals navigate social environments by adopting distinct self-conceptions aligned with various societal roles. These identities are not fixed traits but are constructed through personal actions and the social feedback individuals receive in context-specific interactions. Each social role, such as student, teacher, or friend, carries a set of expectations and norms that influence how people think, feel, and behave within that...
