Mark Watson offers this helpful guide to Semantic Web programming, including discussion about the Calais Web Service.

Klezio is an Semantic RSS Aggregation Portal. It fetches news from RSS feeds, uses openCalais to retrieve the semantic and fetches many interesting stuff (Context) such as Wikipedia, Wikinews, Flickr, twitter and delicious stuff, it also suggests connexe news to the reader.

The idea is to surround the news item with relevant data coming from great apps.

The website is brand new and perfectible, and I'm working on it.

Dublin Core is a metadata standard, even though the use of Dublin Core meta-tags could increase the pages prominence in search engine retrieval lists.

Thinkpedia is a new way to navigate and explore the contents of Wikipedia. It is what we call a "Visual Wiki". Thinkpedia uses SemanticProxy in order to extract semantics out of Wikipedia articles, which are then shown in an interactive visualization which is created with Thinkmap.

During the early days of the Internet in the mid and late 90’s software professionals and Internet users waited in angst for computers to become as smart as people by using artificial intelligence (computers using human reason combined with processing power thousands of times faster than human brain’s processing power). This never panned out because the artificial intelligence community could never produce computer software that would reason just as people do. I believe they are still trying…

This Python module is a wrapper around the OpenCalais API. It makes REST calls to the OpenCalais API via HTTP POST, then parses and simplifies the JSON responses returned by OpenCalais. You can then access the response data in a much more pythonic manner.

Tested with Python 2.5.

Seattle blogs and photos, for serious.

...mostly Capitol Hill right now though.

FlexSpaces+AIR and FlexSpaces+Browser RIA clients for Alfresco have the following Calais features (using the Calais Integration for Alfresco, also in the Calais gallery): semantic tagging, auto-tagging, semi-automatic tag suggesting, node semantic tag properties editor, multiple semantic tag clouds, automatic geo-location tagging (displayed in a google map). These clients are implemented in Flex, AIR, ActionScript and server-side REST api JavaScript web scripts. (The AIR version supports additional desktop drag/drop features). Developed by Steve Reiner (Integrated Semantics).

This Alfresco server extension leverages the Open Calais service to automatically extract semantic metadata from documents stored in Alfresco, has a semantic auto-tagging action service, tag suggest api, enables use of semantic metadata in search. Tags include linked data URIs, and provide geo-location info if available from Calais. Extracted RDF and/or JSON can be optionally associated with documents. Provides a REST api. Also adds an auto-tagging action to the Alfresco web client. The service is implemented in Java (and REST api webs scripts in server side JavaScript). Developed by Alexander Polev (One Point Consulting Limited) and Steve Reiner (Integrated Semantics). Also see FlexSpaces RIA clients for Alfresco (from Integrated Semantics), in the Calais gallery.
