The semantic mapping of the English language is the key to making Natural Language Processing (NLP) effective. Cognition's unique Semantic Map, which it built over the past 24 years, is the most comprehensive and complete map of the English language available today. It can be used in support of the Semantic Web for semantic search, search tools, business analytics, machine translation, document search, context search, and much more.

In my previous article, I introduced the Map/Reduce model as a powerful model for parallelism. However, although Map/Reduce is simple, powerful, and provides a good opportunity to parallelize algorithm, it is based on a rigid procedural structure that requires injection of custom user code and therefore it is not easy to understand the big picture from a high level. You need to drill into the implementation code of the map and reduce functions in order to figure out what is going on.

Argument maps are diagrams that display the structure of an argument. By combining pictures and words, argument maps help people to create better arguments and analyses. iLogos is a freely-available, cross-platform tool that allows you to easily construct and share argument maps.

"This research is grounded in the anthropological understanding that each individual is a unique 'energy source' (Bateson 1972) responsible for acting upon their socially and culturally inflected interpretations in an equally particular way. These indexes capture the actual moments of interaction, of the coming together of individuals in conversational and behavioural exchange (Rapport and Overing 2000). The indexes in this research focus on the socio-cultural field (rather than physical, archaeological or linguistic sub-disciplines), which has been a key element of the discipline since its establishment in the 19th century. Above all, this report highlights how this Cultural Mapping project will offer unparalleled global access into anthropology's own minimal definition: that is, a means to see the Other as Self, and the Self as Other."

Interesting work, based in anthropology

A Semantic Map is kind of like a dictionary, in that it's a representation of Cognition's ability to define things. Cognition claims that its Semantic Map has over 10 million semantic connections; over 4 million semantic contexts (word meanings that create contexts for specific meanings of other related words); over 536,000 word senses (word and phrase meanings); 75,000 concept classes (or synonym classes of word meanings); 7,500 nodes in the technology's ontology or classification scheme; and 506,000 word stems (roots of words) for the English language.

KML is a file format used to display geographic data in an earth browser, such as Google Earth, Google Maps, and Google Maps for mobile. A KML file is processed in much the same way that HTML (and XML) files are processed by web browsers. Like HTML, KML has a tag-based structure with names and attributes used for specific display purposes. Thus, Google Earth and Maps act as browsers for KML files.

As the need for fresh water increases, growing populations across the globe will increasingly turn to groundwater to slake their thirst. But where will we find that water? UNESCO's World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) created this map, along with several others, to serve as a guide to the world's groundwater resources in aquifers and other groundwater environments.

GMT is an open source collection of ~60 tools for manipulating geographic and Cartesian data sets (including filtering, trend fitting, gridding, projecting, etc.) and producing Encapsulated PostScript File (EPS) illustrations ranging from simple x-y plots via contour maps to artificially illuminated surfaces and 3-D perspective views. GMT supports ~30 map projections and transformations and comes with support data such as GSHHS coastlines, rivers, and political boundaries.

OpenLayers makes it easy to put a dynamic map in any web page. It can display map tiles and markers loaded from any source. MetaCarta developed the initial version of OpenLayers and gave it to the public to further the use of geographic information of all kinds. OpenLayers is completely free, Open Source JavaScript, released under a BSD-style License

What if you could contribute to a computational (Map-Reduce) job by simply pointing your browser to a URL? Surely your social network wouldn't mind opening a background tab to help you crunch a dataset or two! Instead of focusing on high-throughput proprietary protocols and high-efficiency data planes to distribute and deliver the data, we could use battle tested solutions: HTTP and your favorite browser.

Crosswalks are documents that map metadata elements between different metadata standards. The crosswalk may be presented as a document for humans to read, in which case the crosswalking process must be performed by humans who are referencing the document. Alternatively, a crosswalk document may be expressed in such a way that a computer can automatically perform a mapping from one metadata standard to another.

This article describes the motivation for and development of a project I have called PepysMap. PepysMap was inspired by the excellent 'blog of the diary of Samuel Pepys run by Phil Gyford 1. Phil posts diary entries day by day (currently for the year 1662). Each blog post contains the text of the diary entry hyperlinked to pages containing detail of people, places and cultural artifacts referenced from the text. The goal of PepysMap is to shadow the development of the Pepys blog by creating a topic map for each diary entry, showing the relationships between people, places and cultural artifacts.

KML is a file format used to display geographic data in an Earth browser such as Google Earth, Google Maps, and Google Maps for mobile. KML uses a tag-based structure with nested elements and attributes and is based on the XML standard. All tags are case-sensitive and must be appear exactly as they are listed in the KML Reference. The Reference indicates which tags are optional. Within a given element, tags must appear in the order shown in the Reference.

Welcome to the National Center for Biomedical Ontology's BioPortal. BioPortal is a Web-based application for accessing and sharing biomedical ontologies. New features in BioPortal 2.0 include: * Full ontology navigation using Flash visualization * Web-service access to BioPortal content and capabilities, which enables developers to use our BioPortal services in their tools. * Ability to add Marginal Notes to classes in BioPortal ontologies, a feature that enables the community to comment on ontologies and to discuss their contents * Ability to create Point to Point Mappings between concepts in different BioPortal ontologies * Bulk export of ontology-to-ontology mappings in RDF format * Navigation of multiple ontologies, which enables users to have several ontologies opened simultaneously in different tabs in the user interface * URIs for all ontology content, which enable developers to access and share BioPortal content from their applications * Improved support through Protégé for ontologies in OWL format

Sensemaking is the process through which humans put together understanding of related information. Sensemaking has been said to involve changes in cognitive representations during a human information processing task. Collection sensemaking involves understanding a collection of media entities, as a whole. One example of a sensemaking task is to compare the damage from Hurricane Katrina to homes, personal effects, and community buildings in different areas of New Orleans. Connected visual and semantic representations provide perspective to support users involved in collection sensemaking tasks. A zoomable map organizes images based on location at varying scales. Multiscale clusters based on zoom level organize images associated with events. The clusters afford contextualized thumbnail browsing and also maintain uniform information density on the map. Metadata enhances context and memory in the process of collection sensemaking.

TagMaps is a toolkit to visualize text (well, tags) geographically on a map.

10 Pillars of Knowledge is a systematic map of human knowledge. It presents, at a glance, the structure of knowledge and the meaningful relations among the main fields. Human knowledge is composed of 10 pillars: Foundations, Supernatural, Matter and Energy, Space and Earth, Non-Human Organisms, Body and Mind, Society, Thought and Art, Technology, History

With formal negotiations on the new international climate change treaty due to open in three weeks time, Independent readers are starting to work with the Debategraph community to develop a comprehensive map of the issues around climate change that are confronting the negotiators.

Argunet is an open platform for creating, sharing and presenting argument maps.
