# The primary intention of creating aTags is not the categorization of the document, but the representation of the key facts inside the document. Key facts in the biomedical domain might be, for example, "Protein A interacts with protein B" or "Overexpression of protein A in tissue B is the cause of disease C". # An aTag is comprised of a set of associated entities. The size of the set is arbitrary, but will typically lie between 2 and 5 entities. For example, the fact "Protein A binds to protein B" can be represented with an aTag comprising of the three entities "Protein A", "Molecular interaction" and "Protein B". Similarly, the fact "Overexpression of protein A in tissue B is the cause of disease C" can be represented with an aTag comprising of the four entities "Overexpression", "Protein A", "Tissue B" and "Disease C". # Each document or database entry can be described with an arbitrary number of such aTags. Each aTag can be associated with the relevant portions of text or data in a fine granularity. # The entities in an aTag are not simple strings, but resources that are part of ontologies and RDF/OWL-enabled databases. For example, "Protein A" and "Protein B" are resources that are defined in the UniProt database, whereas "Molecular Interaction" is a class in the branch of biological processes of the Gene Ontology. They are identified with their URIs.

A system and method for organizing knowledge in such a way that humans can find knowledge, learn from it, and add to it as needed is disclosed. The exemplary system has four components: a knowledge base, a learning model and an associated tutor, a set of user tools, and a backend system. The invention also preferably comprises a set of application programming interfaces (APIs) that allow these components to work together, so that other people can create their own versions of each of the components. In the knowledge web a community of people with knowledge to share put knowledge in the database using the user tools. The knowledge may be in the form of documents or other media, or it may be a descriptor of a book or other physical source. Each piece of knowledge is associated with various types of meta-knowledge about what the knowledge is for, what form it is in, and so on. The information in the knowledge base can be created specifically for the knowledge base, but it can also consist of information converted from other sources, such as scientific documents, books, journals, Web pages, film, video, audio files, and course notes. The initial content of the knowledge web comprises existing curriculum materials, books and journals, and those explanatory pages that are already on the World Wide Web. These existing materials already contain most of the information, examples, problems, illustrations, even lesson plans, that the knowledge web needs. The knowledge base thus represents the core content (online documents or references to online or offline documents); the meta-knowledge that was created at the time of entry; and a number of user annotations and document metadata that accumulate over time about the usefulness of the knowledge, additional user opinions, certifications of its veracity and usefulness, commentary, and connections between various units of knowledge.

"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

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.

Wikipedia, the free online encyclopedia, has challenged the way that reference works are used and understood, and even the way that the collective enterprise of knowledge construction and circulation is itself conceptualized. The article presents an ethnographic study of Wikiversity, an educationally-oriented sister project to Wikipedia. It begins by providing an overview of the orientations and aims of Wikiversity, which seeks to provide for participants both open educational contents and an open educational community. It then undertakes a detailed examination of this project's emerging, overlapping communities and cultures by providing descriptions produced through a combination of ethnographic techniques. These descriptions focus on the experiences of a participant-observer in the context of an 11-week course developed and delivered via Wikiversity, titled Composing Free and Open Online Educational Resources. These descriptions are discussed and interpreted through reference to qualitative studies of the more developed dynamics of the Wikipedia effort - allowing this study to trace the possible trajectories for the future development of the fledgling Wikiversity project. In this way, this paper investigates the communal and cultural dynamics of an undertaking that - should it meet only with a fraction of Wikipedia's success - will be of obvious significance to education generally.

Virtual worlds are governed not only by the source code used to develop the world, but also by civil code documents that establish a governance structure that constrains the interactions of users of the virtual world and regulates relationships among stakeholders of the virtual world. While previous research has examined specific aspects of these documents, this paper analyzes these governing documents as a totality. By examining the totality of and the interplay among the governing documents of a number of established social worlds, this paper seeks to discover insights that can prove valuable both for scholarly understanding of social world governance and for the various stakeholders of social worlds. Following this analysis, the paper offers a set of policy recommendations and considerations to facilitate the development of governing documents that more democratically and equally serve the needs and rights of all stakeholders in virtual worlds. The paper concludes that virtual worlds and their governing documents are boundary objects with agency, in that they are the result of interactions among stakeholder groups and in turn reshape the relationships among those stakeholder groups.

COSMO is the proposed Common Semantic Model, viewed as consisting of a lattice of ontologies which will serve as a set of basic logically-specified concepts (classes, relations, functions, instances) with which the meanings of all terms and concepts in domain ontologies can be specified. The most important function of the COSMO is to serve as a Foundation Ontology that has a sufficient inverntory of fundamental concept representations so that it can support utilities to translate assertions of fundamentally different ontologies into the terminology and format of each other. The use of a common set of defining concepts will permit accurate interoperability of knowledge-based systems using the logical relations of their ontologies as the basis for reasoning in the system. The COSMO can also be used as the starting ontology for creation of more specialized domain ontologies.

Sensemaking involves turning circumstances into a situation that is comprehended explicitly in words and that serves as a springboard into action. In this paper we take the position that the concept of sensemaking fills important gaps in organizational theory. The seemingly transient nature of sensemaking belies its central role in the determination of human behavior, whether people are acting in formal organizations or elsewhere. Sensemaking is central because it is the primary site where meanings materialize that inform and constrain identity and action. The purpose of this paper is to take stock of the concept of sensemaking. We do so by pinpointing central features of sensemaking, some of which have been explicated but neglected, some of which have been assumed but not made explicit, some of which have changed in significance over time, and some of which have been missing all along or have gone awry. We sense joint enthusiasm to restate sensemaking in ways that make it more future oriented, more action oriented, more macro, more closely tied to organizing, meshed more boldly with identity, more visible, more behaviorally defined, less sedentary and backward looking, more infused with emotion and with issues of sensegiving and persuasion. These key enhancements provide a foundation upon which to build future studies that can strengthen the sensemaking perspective.

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.

"The value of any individual piece of knowledge is about the value of any individual piece of lego," Wilbanks said in a keynote address to the Open Access and Research Conference held in Brisbane last week. "It's not that much until you put it together with other legos." He says the ability to connect knowledge brings scientific revolutions. For example Watson and Crick's breakthrough on the structure of DNA involved them reading all the scientific papers on nucleotide bonding and encoding it in the form of a physical model, says Wilbanks. But this kind of "human scale" analysis is no longer feasible in an age when automated laboratory processes generate vast amounts of information faster than the human mind can process it. "For example, we have 45,000 papers about one protein or one gene," says Wilbanks. He says a scientist might once have analysed the impact of one drug on one gene, but now pipetting robots are capable of analysing 25,000 genes at a time. "Most of the research says the smartest of us can handle five or six independent variables at once - not 25,000," he says

"The semantic web proposes to inject machine meaningful data into the existing human language oriented web. As part of this effort, on the semantic web, URIs are used to identify entities. But there is currently no standard way to specify what it is that any given URI is to identify, or to whom, or when. Recent work in linguistics offers ideas for a solution to this lack. It focuses on the pragmatics of actual language use among ensembles of people. Also, the World Wide Web provides a set of technologies, in the form of socially constructed web sites, that could be employed to provide a solution. In this paper, I suggest how such socially constructed web sites could be used to address the problem of establishing common ground among a community of machines of the referent of a URI used on the semantic web. The result is a proposal to automate social meaning by creating societies of machines that share knowledge representations identified by URIs."

What tagging does point to convincingly is the social aspect of naming. In a given natural language, many sorts of identifiers, such as common words, are socially centralized. Other sorts of identifiers, such as proper names, are socially decentralized, varying from local context to local context. Black has noticed a correspondence between this socially grounded identification process and the use of socially constructed Web sites.

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 Cultural Revival Dialog - Building the Europe of the Future Together - was organized by the European Movement Croatia in cooperation with the University of Oslo Knowledge Federation Project, on occasion of the 60th anniversary of the International European Movement. The invitation letter was sent to prominent Croatian researchers, policy makers and media workers, inviting them to a free and open dialog about the prospects for contemporary cultural revival. As always, the purpose of this Key Point Dialog was to come closer to the Key Point - an inspiring vision of the cultural revival, which The Club of Rome considered to be the solution to our global issues, or to the world problematique as they called them. This time we began our dialog by reflecting about a specific theme, the Sheng Zhen Qigong. The intention behind this reflection was to become aware of the nature of our present cultural turning point, of the obstacles that hinder us from changing course, and of the opportunities that a new direction may make available.

The Society for Integrative and Comparative Biology (SICB) is one of the largest and most prestigious professional associations of its kind. Formed as the American Society of Zoologists through a 1902 merger of two societies, the Central Naturalists and the American Morphological Society, its focus has remained to integrate the many fields of specialization which occur in the broad field of biology. Throughout most of its history the society was known as the American Society of Zoologists and changed its name to the Society for Integrative and Comparative Biology in 1996 to reflect the scientific breadth, integrative approaches, and interests of its membership across all disciplines of biology. The SICB is organized around disciplinary divisions, each relevant to a major segment of biology.

'"A Science of Non-Classical Dynamics Based on the Progressive Evolution of the Larger Whole" In this paper, I am trying to lay out a new form of computation, which focuses on the harmony reached in a system. This type of computation in some way resembles certain recent results in chaos theory and complexity theory. However, the orientation of harmony-seeking computation is toward a kind of computation which finds harmonious configurations, and so helps to create things, above all, in real world situations: buildings, towns, agriculture, and ecology. I try to show that this way of thinking about computation is closer to intuition and personal feeling than the processes we typically describe as "computations." It is also more useful, potentially, in a great variety of tasks we face in building and taking care of the surface of the Earth, and quite different in character since it is value-oriented, not value-free. Examples are taken from art, architecture, biology, physics, astrophysics, drawing, crystallography, meteorology, dynamics of living systems, and ecology'

A tag cloud is a list of words in different sizes and colors, with or without a sense of depth (3D), meant to represent the statistical importance of keywords mentioned in a particular document base (a blog, a website, twitter,…). It serves as an indicator of the relative importance of the use of certain ideas in the document base at hand. It is a bottom-up, very fuzzy method for the synthesis of knowledge from an arbitrarily big aggregate of (text) data. Because it rests entirely on statistics, very often there is absolutely no relationships between the keywords of a tag cloud. Worse even, if they existed (by pure chance), there is absolutely no way of finding out about the meaning of those relationships.

n the IS field there is a growing recognition of the importance of theorizing the IT artifact and its organizational and societal context from a pragmatic and action-oriented perspective. Over the years, a number of events and journal special issues have been devoted to this topic (e.g. the Language/Action Perspective workshops 1996-2005 and special issues of CACM and Data and Knowledge Engineering, the Understanding Sociotechnical Action workshops and special issue of IJTHI, the Action in Language, Organizations and Information Systems conferences and EJIS special issue, and the Pragmatic Web conference). The aim of SIGPrag is to provide a much needed centre of gravity and to facilitate exchange of ideas and further development of this area of IS scholarship.

In the process of knowledge discovery, workers examine available information in order to make sense of it. By sensemaking, we mean interacting with and operating on the information with a variety of information processing mechanisms [3,18]. Previously, we introduced a concept that uses the spreadsheet metaphor with cells containing visualizations of complex data. In this paper, we extend and apply a cognitive model called "visual sensemaking " to the Visualization Spreadsheet. We use the task of making sense of a large Web site as a concrete example through out the paper for demonstration. Using a variety of visualization techniques, such as the Disk Tree and Cone Tree, we show that the interactions of the Visualization Spreadsheet help users draw conclusions from the overall relationships of the entire information set.

"This paper proposes the creation of an Augmented Social Network (ASN) that would build identity and trust into the architecture of the Internet, in the public interest, in order to facilitate introductions between people who share affinities or complimentary capabilities across social networks. The ASN has three main objectives: 1) To create an Internet-wide system that enables more efficient and effective knowledge sharing between people across institutional, geographic, and social boundaries. 2) To establish a form of persistent online identity that supports the public commons and the values of civil society. 3) To enhance the ability of citizens to form relationships and self-organize around shared interests in communities of practice in order to better engage in the process of democratic governance. In effect, the ASN proposes a form of "online citizenship" for the Information Age."

Way ahead of its time, and I believe Facebook's (and LinkedIn's, and Plaxo's, and...) successes largely substantiate the emphasis the authors place on the significance of rich support for social trust and identity mechanisms.

In this paper, we challenge the universality of three basic assumptions prevalent in organizational decision support and strategy: assumptions of order, of rational choice, and of intent. We describe the Cynefin framework, a sense-making device we have developed to help people make sense of the complexities made visible by the relaxation of these assumptions. The Cynefin framework is derived from several years of action research into the use of narrative and complexity theory in organizational knowledge exchange, decision-making, strategy, and policy-making. The framework is explained, its conceptual underpinnings are outlined, and its use in group sense-making and discourse is described. Finally, the consequences of relaxing the three basic assumptions, using the Cynefin framework as a mechanism, are considered.
