Organizational modeling with a semantic wiki: formalization of content and automatic diagram generation
A key to maintain Enterprises competitiveness is the ability to describe, standardize, and adapt the way it reacts to certain types of business events, and how it interacts with suppliers, partners, competitors, and customers.
In this context the field of organization modeling has emerged with the aim to create
models that help to create a state of self-awareness in the organization.
This project's context is the use of Semantic Web in the Organizational modeling area. The Semantic Web technology advantages can be used to improve the way of modeling
organizations. This was accomplished using a Semantic wiki to model organizations. Our
research and implementation had two main purposes: formalization of textual content in
semantic wiki pages; and automatic generation of diagrams from organization data stored in the semantic wiki pages.Orientador: Pedro campos e Co-orientador: David Aveir

A short survey of discourse representation models
With the advancement of technology and the wide adoption of ontologies as knowledge representation formats, in the last decade, a handful of models were proposed for the externalization of the rhetoric and argumentation captured within scientific publications. Conceptually, most of these models share a similar representation form of the scientific publication, i.e. as a series of interconnected elementary knowledge items. The main differences are given by the terminology used, the types of rhetorical and/or argumentation relations connecting the knowledge items and the foundational theories supporting these relations. This paper analyzes the state of the art and provides a concise comparative overview of the five most prominent discourse representation models, with the goal of sketching an unified model for discourse representation
MEASURING WEB 2.0 EFFICIENCY
Any potential investment assumes, from the investor’s point of view, answering alegitimate question: What is the value returned by the current investment? Investing in the newsemantic technologies in the area of Web 2.0 and Enterprise 2.0 are no exception to this rule. Theresearch at hand combines a review of the relevant literature with action research, in order toidentify coherent and relevant methods for the measurement of the benefits arising from aninvestment in the new wave of knowledge management and organizational memory buildingtechnologies. The paper is based on the classic ROI computation, attempting to build a newcomputation model, well suited to measure the success of an implementation of the informationalmemory. The valuation model (enforced and explained by means of a case study) may be alsoregarded as a measurement model for the costs and benefits of building organizational memory atthe economic entity level.Organizational knowledge, ROI, computation model, Web 2.0, Semantic Web
The Evolution of Wikipedia's Norm Network
Social norms have traditionally been difficult to quantify. In any particular
society, their sheer number and complex interdependencies often limit a
system-level analysis. One exception is that of the network of norms that
sustain the online Wikipedia community. We study the fifteen-year evolution of
this network using the interconnected set of pages that establish, describe,
and interpret the community's norms. Despite Wikipedia's reputation for
\textit{ad hoc} governance, we find that its normative evolution is highly
conservative. The earliest users create norms that both dominate the network
and persist over time. These core norms govern both content and interpersonal
interactions using abstract principles such as neutrality, verifiability, and
assume good faith. As the network grows, norm neighborhoods decouple
topologically from each other, while increasing in semantic coherence. Taken
together, these results suggest that the evolution of Wikipedia's norm network
is akin to bureaucratic systems that predate the information age.Comment: 22 pages, 9 figures. Matches published version. Data available at
