"FINDINGSCollective intelligence has already been proven to work, and CI systems can be designed and managed to fit specific needs.CI building blocks, or "genes," can be recombined to create the right kind of system.Four main questions drive CI "genome" design: What is being done? Who is doing it? Why? How?"

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.

Media Cloud is a project that tracks news content comprehensively - providing open, free, and flexible tools. This will allow unprecedented quantitative analysis of media trends. For instance, some of our driving questions are: 1. Do bloggers introduce storylines into mainstream media or the other way around? 2. What parts of the world are being covered or ignored by different media sources? 3. Where do stories begin? 4. How are competing terms for the same event used in different publications? 5. Can we characterize the overall mix of coverage for a given source? 6. How do patterns differ between local and national news coverage? 7. Can we track news cycles for specific issues? 8. Do online comments shape the news?

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".

Named Graphs is the idea that having multiple RDF graphs in a single document/repository and naming them with URIs provides useful additional functionality built on top of the RDF Recommendations.
