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.

Sensing importance across a sea of dynamic systems with constantly changing data requires the accumulation and persistence of context. (I am using the term persistence here to mean storing/saving what one has observed and learned - in a database for example.)

What lies at the intersection of journalism and videogames? This research project seeks to understand the ways videogames can be used in the field of journalism, providing examples, theoretical approaches, speculative ideas, and practical advice about the past, present, and future of games and journalism.

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".

Despite significant growth in the number of research papers available through open access, principally through author self-archiving in institutional archives, it is estimated that only c. 20% of the number of papers published annually are open access. It is up to the authors of papers to change this. Why might open access be of benefit to authors? One universally important factor for all authors is impact, typically measured by the number of times a paper is cited (some older studies have estimated monetary returns to authors from article publication via the role citations play in determining salaries). Recent studies have begun to show that open access increases impact. More studies and more substantial investigations are needed to confirm the effect, although a simple example demonstrates the effect.

What Are "Bayesian Belief Network Models?" Bruce G. Marcot 24 April 2005 In short, a Bayesian belief network (BBN) is simply a way of showing how things interact and cause specific outcomes.
