Here, we present a computational model that learns structures of many different forms and that discovers which form is best for a given dataset. The model makes probabilistic inferences over a space of graph grammars representing trees, linear orders, multidimensional spaces, rings, dominance hierarchies, cliques, and other forms and successfully discovers the underlying structure of a variety of physical, biological, and social domains. Our approach brings structure learning methods closer to human abilities and may lead to a deeper computational understanding of cognitive development.

"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.

DeepPeep is a search engine specialized in Web forms. The current beta version tracks 13,000 forms across 7 domains. DeepPeep helps you discover the entry points to content in Deep Web (aka Hidden Web) sites, including online databases and Web services.

Once students have gathered information on a topic, it is important that they reflect on whether the information they have gathered is sufficient to answer the research question. This requires students to make sense of the information they have gathered-to synthesize the information into new knowledge. In order to address the different leaning modalities that students possess, teachers should have students use a variety of forms of representation for this sensemaking stage (see Forms of Representation matrix).

The Open Knowledge Definition (OKD) sets out principles to define the 'open' in open knowledge. The term knowledge is used broadly and it includes all forms of data, content such as music, films or books as well any other type of information. In the simplest form the definition can be summed up in the statement that "A piece of knowledge is open if you are free to use, reuse, and redistribute it". For details read the latest version of the full definition (with explanatory annotations). The history page includes a changelog and links to all previous versions.

People are changing the way that they consume online information, as well as their expectations about its delivery. The social nature of the Web brings with it an expectation of interaction with information and modern Web design is reflecting that. There are now alternate forms of navigation including the ability to browse by user, tag clouds, tabbed navigation etc. Advances in technology along with these shifts in user expectations are affecting the way that information is laid out on a webpage. Today's websites are aiming for intuitive and usable interfaces which are continuously evolving in response to user needs. Website designers are approaching information design differently and designing simple, interactive websites which incorporate advancements in Web interface design, current Web philosophies, and user needs. Information design for the New Web is simple, it is social, and it embraces alternate forms of navigation.

Theory Garden™ MindDraw™ is the brainchild of Professor Richard J. Boland, Jr. and Dr. Tanvir Y. Goraya, Ph.D.It grows form reserach funded from 1991 to 1994 by the National Science Foundation Porgram on coordination Theory and Collaborative Technology. That award was supplemented by a grant form Digital Equipment Corporation (DEC) and included development of a software tool named Spider. Publications describing the Spider project are listed below.

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.

This document defines a concise bounded description of a resource in terms of an RDF graph [5], as a general and broadly optimal unit of specific knowledge about that resource to be utilized by, and/or interchanged between, semantic web agents. Given a particular node in a particular RDF graph, a concise bounded description is a subgraph consisting of those statements which together constitute a focused body of knowledge about the resource denoted by that particular node. The precise nature of that subgraph will hopefully become clear given the definition, discussion and example provided below. Optimality is, of course, application dependent and it is not presumed that a concise bounded description is an optimal form of description for every application; however, it is presented herein as a reasonably general and broadly optimal form of description for many applications, and unless otherwise warranted, constitutes a reasonable default response to the request "tell me about this resource".

A user can start a Web crawl through 80legs's Web-based interface. The form on the company's site lets them set parameters for the project and upload custom code needed to control how the crawler does its job. For example, a user might want the crawler to find images and check them against a database of copyrighted ones. Deysarkar says his company's crawlers are capable of processing up to two billion pages a day. The company charges $2 for every million pages crawled, plus a fee of three cents per hour of processing used.

Contemplation as a form of detached calm engagement.

Narrative techniques both provide a complementary form of what we will call pre-hypothesis research, but further that the use of narrative research techniques produces, through a single intervention, quantitative conclusions supported by narrative context, fragmented knowledge databases, and a mechanism for measuring impact and more complex issues such as mapping ideation cultures.

Snowden again... Looks like a fairly interesting book is on its way, as well...?

tagCare lets you to maintain all your tags jointly in one place, which is especially useful if you normally use several of these different platforms. Many users apply a variety of different tags within different platforms - and finally get lost among them. For example, it is hard to keep track of consistent spelling variants (e.g. not using "science_fiction" in one case and "scienceFiction" in the other) or of preferred terms (e.g. not using "bike" in one case and "bicycle" in the other). Some documents may be tagged with the general term "dog", others more specifically with "greyhound" or "border_collie". tagCare will help you to apply some structure to your tagging vocabulary so that you will more easily navigate through vocabulary choices and use tags more consistently. In tagCare, a user can assemble all tags which he has used within different systems and may then create his own vocabulary hierarchy, synonym collections and cross-references to related terms to establish some lightweight form of controlled vocabulary. This process is also called "tag gardening". Edited and structured tags will then be used to browse document collections in other platforms and to directly tag documents out of tagCare. tagCare is still under development, a first demo version will be available soon and more features will then be added step by step. tagCare will first support Flickr, Bibsonomy and del.icio.us.

An international research consortium has been formed to create the most detailed and medically useful picture to date of human genetic variation. The 1000 Genomes Project will involve sequencing the genomes of at least a thousand people from around the world. The project will receive major support from the Wellcome Trust Sanger Institute in Hinxton, England, the Beijing Genomics Institute Shenzhen in China and the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH).

This paper addresses the issue of text normalization, an important yet often overlooked problem in natural language processing. By text normalization, we mean converting 'informally inputted' text into the canonical form, by eliminating 'noises' in the text and detecting paragraph and sentence boundaries in the text.

The National Center for Biomedical Ontology is a consortium of leading biologists, clinicians, informaticians, and ontologists who develop innovative technology and methods allowing scientists to create, disseminate, and manage biomedical information and knowledge in machine-processable form. Our visionis that all biomedical knowledge and data are disseminated on the Internet using principled ontologies, such that they are semantically interoperable and useful for improving biomedical science and clinical care. Our resources include the Open Biomedical Ontologies (OBO) library, the Open Biomedical Data (OBD) repositories, and tools for accessing and using this information in research. The Center collaborates with biomedical researchers conducting Driving Biological Projects to enable outside research and stimulate technology development in the Center. The Center undertakes outreach and educational activities (Biomedical Informatics Program) to train future researchers to use biomedical ontologies and related tools with the goal of enhancing scientific discovery.

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.
