The authors describe a generic framework for representing and reasoning with annotated Semantic Web data, a task becoming more important with the recent increased amount of inconsistent and non-reliable meta-data on the web. They formalise the annotated language, the corresponding deductive system and address the query answering problem. Previous contributions on specific RDF annotation domains are encompassed by their unified reasoning formalism as they show by instantiating it on (i) temporal, (ii) fuzzy, and (iii) provenance annotations. Moreover, they provide a generic method for combining multiple annotation domains allowing to represent, e.g., temporally-annotated fuzzy RDF. Furthermore, they address the development of a query language – AnQL – that is inspired by SPARQL, including several features of SPARQL 1.1 (subqueries, aggregates, assignment, solution modifiers) along with the formal definitions of their semantics.

Representing achievements as badges or trophies is a standard practice in online gaming. Awarding badges has also become a key ingredient in “gamifying” online social media experiences. Social systems such as Foursquare, StackOverflow, and Wikipedia have popularized badges as a way of engaging and motivating users. In this paper the authors deconstruct badges and present five social psychological functions for badges in social media contexts: goal setting, instruction, reputation, status/affirmation, and group identification. They argue that future research should further explore these five functions and their application in specific contexts.

In conjunction with the 17th International Conference on “Knowledge Engineering and Knowledge
Management by the Masses” (EKAW 2010) there is a call for papers.

This workshop will not focus on the overall topic of social web applications, e.g. Wikipedia, Facebook and so on, since there are already various initiatives on the topic (e.g. the ICWSM conference as well as various workshops SDOW, etc.) but our main focus will be research conducted on tagging systems, based on the three aforementioned areas. Then, we encourage the submission of research papers that deal with the following topics of interest (but not limited to):

• Semantic Tagging and Linked Data
• Semantics of tagging systems
• Tagging systems versus controlled vocabularies
• Extreme tagging methodologies
• Tagging systems in enterprise environments
• Information retrieval in tagging systems
• Tagging and augmented reality
• Best practices for tagging
• Social aspects of tagging
• Prospective views on the future of tagging systems
• Evolution of tagging systems
• Dynamics of tagging systems
• Ontology learning from tagging systems
• Datasets and baseline for evaluating semantic tagging systems
• Social Network analysis based on tagging systems
• Tag and Resource recommendation
• Tags in genuine Web 2.0 applications vs tags in streamed data (e.g. Twitter)
• User profiles from tagging information
• People-tagging
• Multilingual tagging systems
• User-feedback in tagging systems

The deadline of the submissions is 11th of July 2010, the workshop will be held at the 14th of october.

I have just found a very interesting paper about the application of semantic annotation into the medical domain from 2008.

Here you are the abstract of the paper:

Radiological images contain a wealth of information, such as anatomy and pathology, which is often not explicit and computationally accessible. Information schemes are being developed to describe the semantic content of images, but such schemes can be unwieldy to operationalize because there are few tools to enable users to capture structured information easily as part of the routine research workflow. We have created iPad, an open source tool enabling researchers and clinicians to create semantic annotations on radiological images. iPad hides the complexity of the underlying image annotation information model from users, permitting them to describe images and image regions using a graphical interface that maps their descriptions to structured ontologies semi-automatically. Image annotations are saved in a variety of formats, enabling interoperability among medical records systems, image archives in hospitals, and the Semantic Web. Tools such as iPad can help reduce the burden of collecting structured information from images, and it could ultimately enable researchers and physicians to exploit images on a very large scale and glean the biological and physiological significance of image content.

I have just found a very interesting paper titled “A user-centred evaluation framework for the Sealife semantic Web browsers”.

Abstract: Semantically-enriched browsing has enhanced the browsing experience by providing contextualised dynamically generated Web content, and quicker access to searched for information. However, adoption of Semantic Web technologies is limited and user perception from the non-IT domain sceptical. Furthermore, little attention has been given to evaluating semantic browsers with real users to demonstrate the enhancements and obtain valuable feedback. The Sealife project investigates semantic browsing and its application to the life science domain. Sealife’s main objective is to develop the notion of context-based information integration by extending three existing Semantic Web browsers (SWBs) to link the existing Web to the eScience infrastructure.

Definitely, Life Sciences is a domain where semantic annotation can be very valuable.
