Sensemaking on the Pragmatic Web: A Hypermedia Discourse Perspective
The complexity of the dilemmas we face on an organizational, societal and global scale forces us into sensemaking activity. We need tools for expressing and contesting perspectives flexible enough for real time use in meetings, structured enough to help manage longer term memory, and powerful enough to filter the complexity of extended deliberation and debate on an organizational or global scale. This has been the motivation for a programme of basic and applied action research into Hypermedia Discourse, which draws on research in hypertext, information visualization, argumentation, modelling, and meeting facilitation. This paper proposes that this strand of work shares a key principle behind the Pragmatic Web concept, namely, the need to take seriously diverse perspectives and the processes of meaning negotiation. Moreover, it is argued that the hypermedia discourse tools described instantiate this principle in practical tools which permit end-user control over modelling approaches in the absence of consensus
Memetic algorithms for ontology alignment
2011 - 2012Semantic interoperability represents the capability of two or more systems to
meaningfully and accurately interpret the exchanged data so as to produce
useful results. It is an essential feature of all distributed and open knowledge
based systems designed for both e-government and private businesses, since it
enables machine interpretation, inferencing and computable logic.
Unfortunately, the task of achieving semantic interoperability is very difficult
because it requires that the meanings of any data must be specified in an
appropriate detail in order to resolve any potential ambiguity.
Currently, the best technology recognized for achieving such level of precision
in specification of meaning is represented by ontologies. According to the
most frequently referenced definition [1], an ontology is an explicit
specification of a conceptualization, i.e., the formal specification of the
objects, concepts, and other entities that are presumed to exist in some area of
interest and the relationships that hold them [2]. However, different tasks or
different points of view lead ontology designers to produce different
conceptualizations of the same domain of interest. This means that the
subjectivity of the ontology modeling results in the creation of heterogeneous
ontologies characterized by terminological and conceptual discrepancies.
Examples of these discrepancies are the use of different words to name the
same concept, the use of the same word to name different concepts, the
creation of hierarchies for a specific domain region with different levels of
detail and so on. The arising so-called semantic heterogeneity problem
represents, in turn, an obstacle for achieving semantic interoperability... [edited by author]XI n.s
The next generation of interoperability agents in healthcare
Interoperability in health information systems is increasingly a requirement rather
than an option. Standards and technologies, such as multi-agent systems, have proven to be
powerful tools in interoperability issues. In the last few years, the authors have worked
on developing the Agency for Integration, Diffusion and Archive of Medical Information
(AIDA), which is an intelligent, agent-based platform to ensure interoperability in healthcare
units. It is increasingly important to ensure the high availability and reliability of systems.
The functions provided by the systems that treat interoperability cannot fail. This paper
shows the importance of monitoring and controlling intelligent agents as a tool to anticipate
problems in health information systems. The interaction between humans and agents through
an interface that allows the user to create new agents easily and to monitor their activities
in real time is also an important feature, as health systems evolve by adopting more features
and solving new problems. A module was installed in Centro Hospitalar do Porto, increasing
the functionality and the overall usability of AIDA.This work is funded by National Funds through the FCT-Fundacao para a Ciencia e a Tecnologia (Portuguese Foundation for Science and Technology) within project PEst-OE/EEI/UI0752/2014.

(Neg)Entropic scenarios affecting the wicked design spaces of knowledge management systems
CITATION: Schmitt, U. 2020. (Neg)Entropic scenarios affecting the wicked design spaces of knowledge management systems. Entropy, 22(2):169, doi:10.3390/e22020169.The original publication is available at https://www.mdpi.comThe envisioned embracing of thriving knowledge societies is increasingly compromised by threatening perceptions of information overload, attention poverty, opportunity divides, and career fears. This paper traces the roots of these symptoms back to causes of information entropy and structural holes, invisible private and undiscoverable public knowledge which characterize the sad state of our current knowledge management and creation practices. As part of an ongoing design science research and prototyping project, the article’s (neg)entropic perspectives complement a succession of prior multi-disciplinary publications. Looking forward, it proposes a novel decentralized generative knowledge management approach that prioritizes the capacity development of autonomous individual knowledge workers not at the expense of traditional organizational knowledge management systems but as a viable means to foster their fruitful co-evolution. The article, thus, informs relevant stakeholders about the current unsustainable status quo inhibiting knowledge workers; it presents viable remedial options (as a prerequisite for creating the respective future generative Knowledge Management (KM) reality) to afford a sustainable solution with the generative potential to evolve into a prospective general-purpose technology.https://www.mdpi.com/1099-4300/22/2/169Publisher's versio
Diverse perceptions of smart spaces
This is the era of smart technology and of ‘smart’ as a meme, so we have run three workshops to examine the ‘smart’ meme and the exploitation of smart environments. The literature relating to smart spaces focuses primarily on technologies and their capabilities. Our three workshops demonstrated that we require a stronger user focus if we are advantageously to exploit spaces ascribed as smart: we examined the concept of smartness from a variety of perspectives, in collaboration with a broad range of contributors. We have prepared this monograph mainly to report on the third workshop, held at Bournemouth University in April 2012, but do also consider the lessons learned from all three. We conclude with a roadmap for a fourth (and final) workshop, which is intended to emphasise the overarching importance of the humans using the spac
