Knowledge organization is the problem of arranging and classifying what we collectively know as a society in ways that can be easily understood and communicated to others. The issues addressed in this thesis include the representation and storage of knowledge, semiotics, ontology, classification, systems for knowledge organization, and the visualization and aesthetics of knowledge systems. The Quanta software system is presented as a generic framework for the integrated storage, organization and visualization of human knowledge in interdisciplinary contexts. Novel contributions are made to both technical and conceptual aspects of knowledge organization. Technical contributions include a hypergraph structure for the storage and efficient representation of knowledge, comparative zoomable timelines for the visualization of events in time, circle packing with dynamic loading to visualize trees, and a distributed architecture and protocol for social knowledge systems. rchoetzlein rchoetzlein

TreeSheets The ultimate replacement for spreadsheets, mind mappers, outliners, PIMs, text editors and small databases. Suitable for any kind of data organization, such as Todo lists, calendars, project management, brainstorming, organizing ideas, planning, requirements gathering, presentation of information, etc. It's like a spreadsheet, immediately familiar, but much more suitable for complex data because it's hierarchical. It's like a mind mapper, but more organized and compact. TreeSheets

Importing to 3D Topicscape Pro from MindManager, FreeMind and Personal Brain (and exporting to FreeMind) Personal Brain import Some of our early Beta Users were Personal Brain users, so from the beginning, we gave them a way of importing their information into 3D Topicscape. 3D Topicscape Pro can read .pba files (exported by Personal Brain Pro) directly and build you a 3D landscape of the information from the Brain, including the structure, all files and notes. The transformation is amazing and the view you will have allows relationships and duplications that were never spotted before to be seen clearly. Not only that, but the import extender can go into the PB database directly and extract Labels, Tags and Types directly. Personal Brain's own exporter will not do that for you.

I packaged the latest development version of jOWL into a 0.5 release, available at Google Code. jOWL is an AJAX/javascript extension to jQuery that I am developing. The jOWL library parses and reasons with OWL-DL documents. Supported browsers for this release are Internet Explorer 7 and Firefox 2 & 3. Online Ontology Visualisation Online Ontology Visualisation

Disco Hyperdata Browser

Disco Hyperdata Browser The Disco - Hyperdata Browser is a simple browser for navigating the Semantic Web as an unbound set of data sources. The browser renders all information, that it can find on the Semantic Web about a specific resource, as an HTML page. This resource description contains hyperlinks that allow you to navigate between resources. While you move from resource to resource, the browser dynamically retrieves information by dereferencing HTTP URIs and by following rdfs:seeAlso links.
