In our work the traditional bipartite model of ontologies is extended with the social dimension, leading to a tripartite model of actors, concepts and instances.We demonstrate the application of this representation by showing how community-based semantics emerges from this model through a process of graph transformation. We illustrate ontology emergence by two case studies, an analysis of a large scale folksonomy system and a novel method for the extraction of community-based ontologies from Web pages.

The recent announcement by Microsoft of a bid to acquire Yahoo! in a hostile takeover provides stark evidence of the continuing complexity of the intersection of computing and media businesses battling for dominance in the global market. Just as in the case of Time-Warner and AOL (Klein, 2003), the proposed Microsoft-Yahoo! deal is about convergence. The big difference, however, is the new context of threats and opportunities which have led to Redmond's latest effort to deploy its legendary financial muscle in pursuit of corporate goals of market domination. This difference emerges from changing conditions of networked media-computing which are in part associated with the rise of Web 2.0 and which provide an essential clue to understanding why Web 2.0 occupies such an important position in contemporary thinking about the Internet. As I will explain in this paper, Web 2.0 can itself be understood fully only by locating its emergence and significance within the broad movement of convergence of old and new media forms.

From the start of the 21st century, a new form of employment has emerged in developing countries. It employs hundreds of thousands of people and earns hundreds of millions of dollars annually. Yet it has been almost invisible to both the academic and development communities. It is the phenomenon of "gold farming": the production of virtual goods and services for players of online games. China is the employment epicentre but the sub-sector has spread to other Asian nations and will spread further as online games-playing grows. It is the first example of a likely future development trend in online employment. It is also one of a few emerging examples in developing countries of "liminal ICT work"; jobs associated with digital technologies that are around or just below the threshold of what is deemed socially-acceptable and/or formally-legal.

As it tracks and analyzes thought and actions across the world, the Global Power Barometer (GPB) frequently catches sight of issues that will impact global politics. These are the issues that likely will move the icons in coming weeks. We'll share our peeks at the future as they pass certain momentum thresholds. In future days we'll categorize the "Emerging Issues" and provide snippets about the progress of significant trends.

"The debate within the Web community over the optimal means by which to organize information often pits formalized classications against distributed collaborative tagging systems. A number of questions remain unanswered, however, regarding the nature of collaborative tagging systems including whether coherent categorization schemes can emerge from unsupervised tagging by users. This paper uses data from the social bookmarking site del.icio.us to examine the dynamics of collaborative tagging systems. In particular, we examine whether the distribution of the frequency of use of tags for “popular” sites with a long history (many tags and many users) can be described by a power law distribution, often characteristic of what are considered complex systems. We produce a generative model of collaborative tagging in order to understand the basic dynamics behind tagging, including how a power law distribution of tags could arise. We empirically examine the tagging history of sites in order to determine how this distribution arises over time and to determine the patterns prior to a stable distribution. Lastly, by focusing on the high-frequency tags of a site where the distribution of tags is a stabilized power law, we show how tag co-occurrence networks for a sample domain of tags can be used to analyze the meaning of particular tags given their relationship to other tags."

The paper shows that the tags users choose are not chaotic, but rather quickly converge to a common descriptive set of tags that is almost unchanging over time. Perhaps once the tags have stabilized, coherent URI-based identification schemes could emerge?

Nice paper, thanks. Categories / tags / subjects / topics / issues ... that's what I'm working with right now. p.s. sure would be nice if the email notification included the source URL. I'm far more likely to download the PDF when I see something like www2007.org/paper635.pdf

RPI's Tetherless World Constellation will address this emerging area of "Web Science," focusing on the World Wide Web and it's future use. Faculty in the constellation will explore the research and engineering principles that underlie the Web, will enhance the Web's reach beyond the desktop and laptop computer, and will develop new technologies and languages that expand the capabilities of the Web. We will use powerful scientific and mathematical techniques from many disciplines to explore the modeling of the Web from network- and information- centric views. Our goals will include making the next generation web natural to use while being responsive to the growing variety of policy and social needs, whether in the area of privacy, intellectual property, general compliance, or provenance. The Tetherless World Constellation will design new techniques to explore social, scientific, and legal impacts of the evolving technologies deployed on the Web.

So far, most investments in EI have been driven by a focus on an increase in efficiency and topdown change of business processes in relatively static value chains. Typical deployment of EI has been based on the idea of an enterprise-wide "big bang" transition to a new "best way of working", pre-conceived largely by a corporate elite of engineers and analysts. The resulting system and the related procedures were supposed to enforce this way of working and make sure that the enterprise would reap the benefits (of efficiency) for some time to come, by discouraging subsequent unofficial forms of smaller-scale and/or bottom-up change. This approach was very much enterprise centric and typically weak in accommodating subsequent change. It is however no longer adequate, because enterprises increasingly need to rely on bottom-up initiative, emergence and flexibility, in order to remain competitive. Due to fierce global competition, enterprises can no longer survive with a focus on efficiency and producing more of the same (for a lower price). Instead, enterprises need to concentrate on value innovation and producing more of not the same (with higher margins). To this end enterprises operate increasingly in dynamic value networks.Therefore EI should be geared towards leveraging creativity, collaboration and change in more dynamic networks to release its full potential as an instrument for value creation. A new objective for EI should be: To stimulate value creation based on innovation and co-creation in a context of networked enterprises that is very much defined bottom-up, by creative, committed workers.

The contention made in this article is that ontologies are pivotal to several seemingly disparate technical endeavours that are currently emergent and have had more or less publicity. These include Event Driven Architecture (EDA), Complex Event Processing (CEP), Service Oriented Architecture (SOA), Master Data Management (MDM), which are supported by specific ontological initiatives most notably the Semantic Web, which is further leveraged by Model Driven Architecture (MDA). Furthermore how these efforts are all dependent on the adherence to common standards. These endeavours, and their complementary interrelationships, and specifically their relationship to ontology, are explored in more detail below.

Using segments of rich media makes it possible to aggregate context and meaning on these chunks by using a number of different mechanisms. Starting with a granular node -- be it a sound bite, visual clip or written fact -- it is possible to aggregate contextual metadata through a series of steps that emergently progress from: * Starting with thousands of defined Audio Sound Bites & visual clips * Rating sound bites and clustering them with folksonomy tags * Sequencing audio sound bites within playlists * Collaboratively building larger sequences with nested playlists * Independently controlling the video & audio tracks with 2-dimensional nested playlists * Evaluating Multiple Storylines and Hypotheses with a 2-dimensional playlist matrix * Visualizing complex networks by mapping out feedback loop relationships between nodes

Businesses are moving beyond marketing in virtual worlds and are exploring other applications of virtual worlds (see a recent BusinessWeek article & slideshow). Enabling collaboration among remote workers is one such application (see our past posts and paper on this topic). A variety of virtual world options or platforms have been available for supporting remote work and these include Second Life, Qwaq, Forterra, and Tixeo. Last week I had the rare opportunity to see an emerging virtual world called Wonderland, the product of an open source project, Project Wonderland, sponsored by Sun Microsystems. During a conference call with our colleague Nicole Yankelovich, Principal Investigator of the Collaborative Environments Project at Sun Microsystems, Becky Jestice and I were lucky enough to get a tour of Wonderland. Nicole graciously spent over an hour to show us some of the impressive features of Wonderland. The tour was so impressive that I want to devote a post to some key aspects of Wonderland: * Virtual meeting participants can use voice to communicate with one another; * If necessary, participants can connect to a Wonderland meeting via telephone; * Private conversations between participants are possible in a virtual meeting; * Participants can share applications; and * Anyone can try out Wonderland (see instructions below).

In order to meet the emerging needs of e-Researchers, the DART project proposes a comprehensive end-to end approach to developing a new system for managing research activity and publication.

Global (e.g. organization-wide) patterns emerge from everyday 'local' (i.e. one-to-one or small-group) conversations. The more that people (in interaction) make sense of events and take action in particular ways, the more likely they are to make similar sense and take similar actions in the future. That is, from an informal coalitions perspective, these patterns are not formed by managerial dictat or design but by the nature of the everyday sensemaking that has gone before.

In a striking departure from traditional methods of teaching, a new way for students to gain course credits is emerging. The Eduzendium initiative was proposed by Dr. Sorin A. Matei (Purdue University). In collaboration with Dr. Larry Sanger, co-founder of Wikipedia and now Editor-in-Chief of the Citizendium, and a group of Purdue graduate students, he has designed a set of template policies, rules and educational methods that allow incorporating wiki style collaboration in the educational process. The policies have been pretested at Purdue and will soon be released to the educational community through Eduzendium.

Bringing Wisdom to Emerging Technology We are at an amazing and critical juncture in human history. If we continue on our current path, we face many potential disasters: overpopulation, shortages of water, oil, and raw materials, financial instability, disease, terrorism, war, and the destruction of species and ecosystems (eg. see Jeffrey Sachs "Common Wealth: Economics for a Crowded Planet"). But the next few decades will also bring advances in science and technology which may dramatically improve our lives. It is remarkable that we are simultaneously on the verge of major revolutions in biology, neuroscience, psychology, artificial intelligence, nanotechnology, and fundamental physics.

One of the highlights of October's Web 2.0 Summit in San Francisco was the emergence of 'Semantic Apps' as a force. Note that we're not necessarily talking about ...

Cognitive Edge is focused on rejuvenating management practices to better equip organisations when addressing intractable problems or seizing new opportunities in uncertain and complex situations. Where traditional approaches have failed to deliver success, Cognitive Edge techniques enable the emergence of fresh and insightful solutions seen from multiple perspectives.

Last week, I participated in a WWW2007 panel called "Multimedia Metadata Standards in a Semantic Web 3.0", where I took the opportunity to declare the Semantic Web dead. As you can imagine, such a declaration in front of a crowd of semantic web researchers provoked many responses. While I believe panels should be provocative and entertaining, I also have specific reasons for why I went as far as calling the Semantic Web "dead". Let me explain what I mean.

A twine about the concept of an emerging global brain. What are the similarities and differences between the Internet and the human brain and nervous system? What are the steps that are leading us towards a global brain? What are the implications of the global brain?

Quick, incremental updates, along with heavy user involvement, are key characteristics of an emerging software development paradigm championed by a new generation of Web 2.0 start-ups. The new process, which some champions call "application development 2.0," contrasts markedly with the traditional corporate waterfall process that separates projects into several distinct phases, ranging from requirements to maintenance. Nonetheless, application development 2.0 can bring significant benefits to corporate IT shops if managers and developers are willing to change.
