Twitter Data is a simple, open, semi-structured data representation format for embedding machine-readable, yet human-friendly, data in Twitter messages. This data can then be transmitted, received, and interpreted in real time to enable powerful new kinds of applications to be built on the Twitter platform.
This text sets out a series of approaches to the analysis and synthesis
of the World Wide Web, and other web-like information structures.
A comprehensive set of research questions is outlined, together with
a sub-disciplinary breakdown, emphasising the multi-faceted nature of
the Web, and the multi-disciplinary nature of its study and development.
These questions and approaches together set out an agenda for
Web Science, the science of decentralised information systems. Web
Science is required both as a way to understand the Web, and as a way
to focus its development on key communicational and representational
requirements. The text surveys central engineering issues, such as the
development of the Semantic Web, Web services and P2P. Analytic
approaches to discover the Web's topology, or its graph-like structures,
are examined. Finally, the Web as a technology is essentially socially
embedded; therefore various issues and requirements for Web use and
governance are also reviewed.

NaturalOWL is an open-source natural language generation engine written in Java. It produces descriptions of individuals (e.g., items for sale, museum exhibits) and classes (e.g., types of exhibits) in English and Greek from OWL DL ontologies. The ontologies must have been annotated in RDF with linguistic and user modeling resources. We demonstrate a plug-in for Protege that can be used to produce these resources and to generate texts by invoking NaturalOWL. We also demonstrate how NaturalOWL can be used by robotic avatars in Second Life to describe the exhibits of virtual museums. NaturalOWL demonstrates the benefits of Natural Language Generation (NLG) on the Semantic Web. Organizations that need to publish information about objects, such as exhibits or products, can publish OWL ontologies instead of texts. NLG engines, embedded in browsers or Web servers, can then render the ontologies in multiple natural languages, whereas computer programs may access the ontologies directly.
Inspired by Yahoo's Pipes, DERI Web Data Pipes implement a generalization which can also deal with formats such as RDF (RDFa), Microformats and generic XML.
DERI Pipes are Open Source Software, ad as such they can be easily extended and applyed in use cases where a local deployment is needed.
DERI Pipes provides a rich web GUI where pipes can be graphically edited, debugged and invoked. The execution engine is also available as a standalone JAR, which is ideal for embedded use.
DERI Pipes, in general, produce as an output streams of data (e.g. XML, RDF,JSON) that can be used by applications. However, when invoked by a normal browser, they will provide a end user GUI for the user to enter parameter values and browse the results
Sphinx is a full-text search engine, distributed under GPL version 2. Commercial license is also available for embedded use.
Generally, it's a standalone search engine, meant to provide fast, size-efficient and relevant fulltext search functions to other applications. Sphinx was specially designed to integrate well with SQL databases and scripting languages. Currently built-in data sources support fetching data either via direct connection to MySQL or PostgreSQL, or using XML pipe mechanism (a pipe to indexer in special XML-based format which Sphinx recognizes).
The Web is ephemeral. Pages change frequently, and it is nearly impossible to find data or follow a link after the underlying page evolves. We present Zoetrope, a system that enables interaction with the historical Web (pages, links, and embedded data) that would otherwise be lost to time. Using a number of novel interactions, the temporal Web can be manipulated, queried, and analyzed from the context of familar pages. Zoetrope is based on a set of operators for manipulating content streams. We describe these primitives and the associated indexing strategies for handling temporal Web data. They form the basis of Zoetrope and enable our construction of new temporal interactions and visualizations.
E-mail is no longer just e-mail, and it arguably hasn't been for some time. Webmail clients like Yahoo's have offered IM and calendar integration for a while, and now Gmail allows video chatting and embedded gadgets. Zenbe, a new startup, is bringing social features, collaboration, and a new perspective on our e-mail routine with things like a sharable wiki, discussions, and even a Twitter sidebar.
# What is Cruxlux about?
# Shining a light on the crux of things. If something's true, it should withstand scrutiny, and if something's wrong, we should be able to help uncover that. With our novel and powerful technology, we allow interactive back-and-forth between different views, making it easy to see counterpoints to a given argument and to identify the root causes of disagreement on an question. Besides participating on this site, the Cruxlux platform can be embedded on other sites, to enable their visitors to participate in inter-blog debates and chats.
GUESS is an exploratory data analysis and visualization tool for graphs and networks. The system contains a domain-specific embedded language called Gython (an extension of Python, or more specifically Jython) which supports the operators and syntactic sugar necessary for working on graph structures in an intuitive manner. An interactive interpreter binds the text that you type in the interpreter to the objects being visualized for more useful integration. GUESS also offers a visualization front end that supports the export of static images and dynamic movies.
