To manage information quality (IQ) effectively, one needs to know how IQ changes over time, what causes it to change, and whether the changes can be predicted. In this paper we analyze the structure of IQ change in Wikipedia, an open, collaborative general encyclopedia. We found several patterns in Wikipedia's IQ process trajectories and linked them to article types. Drawing on the results of our analysis, we develop a general model of IQ change that can be used for reasoning about IQ dynamics in many different settings, including traditional databases and information repositories.

This paper surveys information architecture in the context of digital libraries. Key concepts are defined as well as common attributes of information architectures in general. Communications standards - including hybrid TCP/IP-OSI, CORBA, and Web services - are explored, as well as the history of information architecture and related models. A number of digital library projects are analyzed with a focus on their distinct architectures. The key role of information architecture in the design and development of the twenty-first century digital library is detailed throughout.

The SMW+ User Forum is an online community for users and developers of Semantic MediaWiki+ in a commercial or production environment with the purpose to improve and extend Semantic Media Wiki+. SMW+ Forum fuses the social networking aspect of Web 2.0 with semantic technologies.

OWL 2 extends the W3C OWL Web Ontology Language with a small but useful set of features that have been requested by users, for which effective reasoning algorithms are now available, and that OWL tool developers are willing to support. The new features include extra syntactic sugar, additional property and qualified cardinality constructors, extended datatype support, simple metamodeling, and extended annotations.

n the IS field there is a growing recognition of the importance of theorizing the IT artifact and its organizational and societal context from a pragmatic and action-oriented perspective. Over the years, a number of events and journal special issues have been devoted to this topic (e.g. the Language/Action Perspective workshops 1996-2005 and special issues of CACM and Data and Knowledge Engineering, the Understanding Sociotechnical Action workshops and special issue of IJTHI, the Action in Language, Organizations and Information Systems conferences and EJIS special issue, and the Pragmatic Web conference). The aim of SIGPrag is to provide a much needed centre of gravity and to facilitate exchange of ideas and further development of this area of IS scholarship.

IkeWiki is a new kind of Wiki (a Semantic Wiki ) developed by SalzburgResearch that allows users to annotate pages and links between pages with semantic annotations. Such annotations are useful because they give machines a certain amount of "understanding" of the content that goes beyond merely displaying the page. This information can then e.g. be used for context-specific presentation of pages, advanced querying, consistency verification or drawing conclusions. Currently, IkeWiki can make use of some of the knowledge represented in RDFS and OWL schemas to display enhanced navigation tools. Furthermore, we implemented a sample "biology ontology" that automatically displays a taxonomy box for biological objects. Although IkeWiki looks and behaves like Wikipedia/MediaWiki in many aspects, it is a complete rewrite, and the system design significantly differs from other Wikis. IkeWiki makes full use of Semantic Web technologies like RDF(S) and OWL using the Jena RDF store, and is implemented as an AJAX-based Rich Internet Application, based on the Dojo Toolkit

Ensembl is a joint project between EMBL - EBI and the Sanger Institute to develop a software system which produces and maintains automatic annotation on selected eukaryotic genomes. Ensembl is primarily funded by the Wellcome Trust. This site provides free access to all the data and software from the Ensembl project. Click on a species name to browse the data.

SWAN (Semantic Web Applications in Neuromedicine) is a project to develop knowledge bases for the neurodegenerative disease research communities, using the energy and self-organization of that community enabled by Semantic Web technology. Created in collaboration with the Alzforum and other partners. Read more about the SWAN project here.

Everything has to do with everything else. Fenfire is a Free Software project developing a computing environment in which you can express these relationships and benefit from them.

ARROWSMITH is interactive software that extends the power of a MEDLINE search. It operates on the output of a conventional search in a way that helps the user see new relationships and form and assess novel scientific hypotheses. It is based on the premise that information developed in one area of research can be of value in another without anyone being aware of the fact.

Sense-Making is an approach to thinking about and implementing communication research and practice and the design of communication-based systems and activities. It consists of a set of philosophical assumptions, substantive propositions, methodological framings, and methods. It has been applied in myriad settings (e.g., libraries, information systems, media systems, web sites, public information campaigns, classrooms, counseling services, and so on), at myriad levels (e.g., intrapersonal, interpersonal, small group, organizational, mass, national, global), and within myriad perspectives (e.g., constructivist, critical, cultural, feminist, postmodern, communitarian). The approach has been developed by Brenda Dervin and is being expanded, transformed, and enriched daily by the efforts of some 100-plus persons worldwide (academics and practitioners, teachers and students). This web site is designed to provide access to these efforts and links to those who are involved. On this site, Sense-Making (capitalized) refers to the methodology; sense-making (not capitalized) refers to the phenomena of making and unmaking of sense.

The Java Text Categorizing Library (JTCL) is a pure java 1.5 implementation of libTextCat which in turn is "a library that was primarily developed for language guessing, a task on which it is known to perform with near-perfect accuracy". It's distributed under the LGPL and can also be used in order to categorize text into arbitrary topics by computing appropiate fingerprints which represent the categories.

The EU IST integrated project Semantic Knowledge Technologies (SEKT) developed and exploited semantic knowledge technologies. Core to the SEKT project has been the creation of synergies by combining the three core research areas ontology management, machine learning and natural language processing.

OpenEdit DAM is an open source Digital Asset Management software used within an enterprise to share documents, photos and web site files online. OpenEdit DAM is built with the OpenEdit Framework (OEF) which is the result of years of testing and agile development.

Science Commons designs strategies and tools for faster, more efficient web-enabled scientific research. We identify unnecessary barriers to research, craft policy guidelines and legal agreements to lower those barriers, and develop technology to make research data and materials easier to find and use.
