Durham, NC – So much for tagging photographs with names, locations and activities yourself – a new cell phone application can take care of that for you.

The system works by taking advantage of the multiple sensors on a mobile phone, as well as those of other mobile phones in the vicinity.

Dubbed TagSense, the new app was developed by students from Duke University and the University of South Carolina (USC) and unveiled at the ninth Association for Computing Machinery’s International Conference on Mobile Systems, Applications and Services (MobiSys), being held in Washington, D.C.

The Third Canadian Semantic Web Symposium, will be held in the University of British Columbia, Vancouver, British Columbia (Aug 5, 2011). As a follow-up to the previous symposium, CSWS 2011 aims at bringing together Canadian and international researchers in semantic technologies and knowledge management to discuss about various issues related to the Semantic Web.

The Third Canadian Semantic Web Symposium 2011 calls for papers in all topics related to semantic web technologies and their applications. The following are some example topics:
· Languages, tools and methodologies for the Semantic Web
· The application of AI technologies in the Semantic Web
· Searching, querying, visualizing and interpreting the Semantic Web
· Semantic Web-based Knowledge Management;
· Semantic Grid and semantic Grid services
· Trust, privacy, security on the Semantic Web
· Ontology design, evolution and management
· Ontology mapping and merging
· Semantic Web and uncertainty
· Description logics and frame logics as ontology formalisms
· Modular, distributed, and multi-ontologies
· Semantic Web technologies for collaboration and cooperation
· Semantic Web Services (description, discovery, invocation, composition)
· Semantic Web and databases
· Practical applications of Semantic Web techniques in e-business, e-commerce, e-government and e-learning
· Semantic Web rule languages and engines
· Social Semantic Web (Web 3.0)

CSWS 2011 will feature two tracks: a Research and a Work-in-Progress track. The objective of the research track is to solicit original papers that present accomplished research on the area of the Semantic Web. The Work-in-Progress track aims at providing an opportunity for practitioners to present their on-going research on principles and applications of the Semantic Web, even when implementation or deployment has not been completed.

Accepted submissions will be published in the symposium Proceeding.

Authors are invited to submit full papers in PDF, Postscript or MS-Word RTF electronically. All papers must be written in English. Research papers can be up to 12 pages in length and Work-In-Progress papers can be up to 6 pages. Papers must be formatted according to Springer’s LNCS style. Please follow the instructions for authors at Springer’s site for authors. To submit papers, please follow visit

Mechanisms for reasoning with context have become increasingly important factors in the Semantic Web. There is a growing need for general and robust reasoning techniques that make it possible to integrate heterogeneous knowledge or to use homogeneous knowledge across different domains.

Research on this topic has so far, and not surprisingly, concentrated on formal ontologies, i.e., on the logical structures that encode the semantics of a software’s domain of application. Work on the Semantic Web as well as on information integration, distributed knowledge management, multi-agent and distributed reasoning has focussed on the relationship between an ontology and its context. This has aimed at clarifying how to relate knowledge that is distributed over many resources. Recent Semantic Web specific developments suggest that aspects of this relation can be captured by means of named graphs (to express meta-information), the use of provenance (to track the context where data/axioms came from) and querying (to facilitate reasoning).

Other neighbouring research areas, though, have also investigated topics that shed light on how to reason with context in the Semantic Web. Ontology Engineering and Maintenance, for instance, has tackled the problems faced by ontology engineers when developing and maintaining an ontology. The yielded automation of the process of ontology development and of its phases (e.g. knowledge elicitation, revision cycles, alignment with pre-existing ontologies etc.) has improved efficiency, reduced the introduction of unintended meanings into ontologies and in general made explicit the relationship between an ontology and its development context. Finally, research on Problem Solving and Agent Communication has explored how an agent’s ontology needs to change at run-time because of interactions with its context – for instance with other agents whose ontologies are not known or with new non-classifiable world situations. This type of research has delivered a deeper understanding of the evolution of an ontology and is often based on non-monotonic reasoning, belief revision or changes of signature, i.e., of the grammar of the ontology’s language, with a minimal disruption to the original theory.

Topics of interest:
This special issue aims at bringing together work on reasoning with context in  the Semantic Web from the integration, development and evolutionary perspectives described above. Submitted articles, which may describe either theoretical results or applications, must clearly pertain to the Semantic Web and/or to semantic technologies. They should  present either Semantic Web specific approaches to reasoning with context, or approaches that have characteristics that are interesting for the Semantic Web (e.g., scalability, bounded reasoning), or approaches that are of value to a larger community containing a non-trivial Semantic Web sub-community (e.g. revision/update techniques and error pin-pointing).

Submissions are welcome on topics relevant to reasoning with context in the Semantic Web and that include but are not limited to:
- Named graphs
- Provenance
- Knowledge representation languages for semantic technologies
- Planning and reasoning about action and change in the Semantic Web
- Ontology fault diagnosis and repair
- Pinpointing of logical errors in contexts and ontologies
- Explanation and justifications in DL ontologies
- Ontology and context evolution, debugging, update and merging
- Inconsistency handling in contexts and ontologies
- Uncertainty handling, defeasible reasoning and argumentation in ontologies
- Non-classical belief revision
- Context revision and theory change in DL ontologies
- Ontology and context versioning
- Semantic difference in ontologies and in contexts
- Information and knowledge integration
- The role of context and ontology in distributed reasoning and knowledge management
- Heuristic and approximate reasoning
- Bounded reasoning and bounded rationality in the Semantic Web
- Adaptive systems and reconfiguration
- Ontology-based data access
- Querying
- Multi-Agent systems in the Semantic Web
- Temporal and spatial reasoning
- Normative reasoning in the Semantic Web
- General problem solving for semantic technologies
- Machine learning for the Semantic Web
- Philosophical foundations of reasoning about context and ontology evolution
- Comparison of uses of contexts and ontologies

Social networks can be a valuable tool when it comes to getting your name out there, but while many businesses have a Facebook page it’s surprising how often little to no effort is put into using them effectively. No mater how diligently you answer comments on your wall, there will come a time when your user base will grow bored. Here are a few sure fire ways to keep them interested and coming back.

Incentive Programs

A good starting place for making sure your user base sticks around is to give them a reason to. It’s pretty commonplace to see sweepstakes and giveaways as a way to encourage more people to comment, like, and generally keep interest high. What is less common and far more effective, however, is to make a game out of it. As an example, if you implemented a system where points are given for various actions—ten points for liking a page, maybe twenty for referring another user to like the page, and five points for every comment posted—you’re immediately giving your users something to work towards and a sense of progression not unlike those found in video games.

Best Using the Point System

Once you have a system like this put in place, it’s important that when an eventual winner, or winners of this game are chosen, no one feels cheated or like their time was wasted. The best way to do this is to foster a sense of community, and make your users feel like they are working together rather than against one another. A good example of a way to implement this is to keep a grand point total as well as an individual point total, and give incentives to the entire community at various points. When the grand total reaches one hundred thousand points lets say, everyone gets a coupon code for five percent off at your or maybe a partner retailer. This increases sales, makes everyone feel like they have won, and keeps interest in your page extremely high.
