Goal and Motivations
Semantic Web Collaborative Spaces such as semantic wikis, semantic social networks, semantic forums, etc. are social semantic software with the mission to bring together human agents and software agents in order to foster knowledge-intensive collaboration, content creation and management, annotated multimedia collection management, social knowledge diffusion and formalising, and more generally speaking ontology-oriented content management life-cycle.
The domain spans from multidisciplinary research to deployed commercial web applications and contributions from all this spectrum are encouraged. The aim of the SWCS 2012 workshop is to exchange ideas, to discuss pressing research questions arising from theoretical studies and practical usage of semantic web collaborative spaces.
an ESWC 2012 Workshop. May 27 or 28, Hersonissos, Greece.
At SePublica we want to explore the future of scholarly communication and scientific publishing. As we are going through a transition between print media and Web media, SePublica aims to provide researchers with a venue in which this future can be shaped.

SePublica@ESWC Workshop on Semantic Publication (May 30, Crete), LNCS Post-proceedings, Best Paper Award by ElsevierSunday, January 16th, 2011
I am a chair of the following workshop (and Michael is on the PC), which is closely related to KWARC’s research interests (specifically KWARC-relevant topics highlighted below):
1st International Workshop on Semantic Publication (SePublica 2011)
at the 8th Extended Semantic Web Conference (ESWC 2011)
May 30th, Hersonissos, Crete, Greece
Keynote by Steve Pettifer, Manchester University, UK: “Utopia Documents and The Semantic Biochemical Journal experiment”
SUBMISSION DEADLINE (extended) March 4
- Best Paper Award sponsored by Elsevier: US$ 750+250 for the most innovative and feasible proposal concerning semantic publishing
- Springer LNCS post-proceedings: A selection of revised versions of the best submissions will be published in the “ESWC 2011 Workshop Highlights” LNCS volume.
The MISSION of the SePublica workshop is to bring together researchers and practitioners dealing with different aspects of Semantic Technologies in the Publishing Industry. How is the Semantic Web impacting the publishing industry? How is our experience of publications changing because of Semantic Web technologies being applied to the publishing industry?
Gathering Information on this community as well as the current state-of-the-art in research and industry.
Venues of the community:
There are several events for the user modelling and adaptation community. However, both are closely related, which one can also see by the recent merge of two of the biggest venues UM and AH. I was told that besides the venues on international ground, ABIS is an important meeting on a national layer (The workshop has solely taken place in Germany, but gathers researchers across Europe).
- ABIS Workshop (Satellite event of the LWA Workshop)
- International Workshop on Semantic Media Adaptation and Personalization (2008)
- International Conference on Intelligent User Interfaces
- International ACM Conference on Recommender Systems
- Artificial Intelligence in Education (CfP 2009)
- User Modeling Inc. (check out more related conference, job postings, and research groups)
- Conference on Adaptive Hypermedia and Adaptive Web-Based Systems: All forms of Web and Hypermedia personalization from personalized search and browsing to recommender systems to personalized E-Learning. (2008)
- International Conference on User Modelling (2007)
- 1st and 7th International Conference on user modelling, adaptation, and personalization (2009): User Modeling (UM, 1986-2007) and Adaptive Hypermedia and Adaptive Web-Based Systems (AH, 2000-2008) have been merged into the annual conference series User Modeling, Adaptation, and Personalization (UMAP)
Professional Solution of Industry
- Amazon: Adaptive Hypermedia in eBusiness: Recommendations based on user preferences and prior history

Notes & Further Readings
- Adaptive Hypermedia (AH) tailors what the user sees to the learner’s goals, abilities, interests, knowledge, etc. [..] offers a selection of links or content most appropriate to the current user (in his current context, whereas context refers to the device). “Adaptive hypermedia is closely related to Web personalization.”
- Adaptive Educational Hypermedia: “Fundamental problem is that learners inevitably have diverse backgrounds, abilities and motivation – and hence highly individual learning requirements.” (AC 2005) Doesn’t target stand-alone systems (unlike intelligent tutoring systems), but hypermedia systems.
- Distinction between adaptation ((automatic) system-driven personalisation and modifications) and adaptability (user-driven personalisation and modifications).
- The Adaptive Web: Methods and Strategies of Web Personalization (Book by Peter Brusilovsky, 2007)
- AHA Project funded by the NLnet Foundation (1997 – up to date): see The Design of AHA
Towards adaptable and adaptive OMDoc (systems)
Looking at the work in the area of adaptive hypermedia, I believe, that ours and their work go well together: We have a strong representation format of mathematical knowledge (focusing on the design so far and slowly moving to ways of manipulating it, see e.g. JOMDoc/ JOBAD), while they have placed good thoughts on the user modelling, strategies for adaptation, and general frameworks for designing adaptive systems.
The motivation and focus of AH, seems to overlap with our work (cf. Peter Brusilovsky; AHA Project; Alexandra Cristea): For example, to improve accessibility of mathematical knowledge, we talk of adapting it, in particular by selecting, sequencing, and presenting mathematical knowledge for a user or community of users.
- Problems with hypermedia applications: (1) Navigational freedom: which links are relevant (for this user)?; (2) Comprehension: what has the user seen before when reaching a certain node? (3) Presentation: what fits the user’s screen? how much network bandwidth and processing power is available? (cf. Talk)
- Opportunities with AH: (1) Guide users towards relevant information (users can reach relevant information more easily and more quickly), (2) Make sure users can understand the presented information, (3) Change the presentation so that it fits the user’s platform and environment (cf. Talk)
Layers of the Adaptive Hypermedia Framework LAOS
If we look at the layers of the LAOS framework (cf. AC 2004), we can see a great overlap to the OMDoc approach. I believe we are much stronger on the content representation, while OMDoc is still missing the user modelling and adaptive layer:
- Domain model (DM) containing a collection of linked resources
- Goal and constraints model (GM) containing goal-related information, such as instructional and pedagogic information about the resources
- User model (UM) containing user-related information, such as information about the learner
- Adaptation model (AM) containing the behaviour and dynamics, such as, a learning style related adaptive strategy
- Presentation model (PM) containing display and machine-related information, such as the foreground-background colour scheme for the course presentation
In order to make OMDoc (systems) adaptable/ adaptive, we need to provide these layers: (1) OMDoc Commons interlinked on different layers, i.e. logical, narrative, rhetorical, argumentative (?); (2) theory morphisms, i.e. mathematical/ logical prerequisites but maybe also rhetorical prerequisites; (3) is missing; (4) is missing; (5) presentation-pipeline.
Flexible, autonome Verhaltenskontrolle: Erlernen und Adaptation von Sensormotorischen Raumrepräsentationen

Hypothesis: PIM benefits from information linkage and information reuse across PIM application.
Method: Using RDF and Semantic Web technologies.
X-COSIM provides the X-COSIMO ontology:
Among others, X-COSIMO defines contextual information in a formal representation for context, the contextual ontology includes concepts such as email, attachment, sender, recipients. Attachments e.g. contextualizes information object, while sender and recipient contextualizes agents in the systems.
Does an X-COSIM enabled desktop provide better support for PIM tasks than a conventional one?
Better means: increased effectiveness (absolute time spend on each task), increased efficiency (goals reached: distance of mouse movements, number of window switches, …), increased satisfaction (questionnaire, ratings, interview).
- 18 participants: 3 graduate students and 15 Ph.D.s students; none of them used the semantic desktop before.
- Introduction (to the scenario, to the dataset, get acquainted to the system), observation, and feedback phase.
- Scenario: Real data select from the organizers of the Night of Computer Science in Koblenz (more than 140 emails, 44 files, 40 files via eMail, …)
- Tasks: (1) organization tasks (familiarization: all emails in one folder and participants had to create a folder structure), (2) lookup tasks (baseline: re-finding information; baseline as this feature was not expected to be of greater benefit in contrast to others), (3) multi-item tasks (evaluation), (4) document-driven collaboration (evaluation), (5) information collation (evaluation)
- Evaluation Wizard: guiding the user through the evaluation; presenting the lookup tasks, …, and questionnaire. The wizard tracked the execution time for each task.
Results: Semantic desktop can improve PIM.

The social bookmarking system BibSonomy has to deal with a lot of spam; which hamper the quality of search results and navigation. This talk focuses on detecting users as spammer, making all their posts invisible in the system. This decision is based on their tagging and personal data such as eMail etc. The authors present a framework that allows for automatic classification of spammers.
How to detect Spammers: Checking all their tags and, possible, the bookmarked sites. Spam posts are identified if:
- Tags describing a web page do not fit to the content of the site.
- Tags and/or topic of a post are not interesting for the system.
- Subjective notion of what is spam
- No cross-check; noise
- Only two classes: spam or non-spam
- Maybe identification of spammers to not granular enough, rather flag posts as spam
- User may have several accounts
- Profile features (digits in name, digits in mails, length of the names, mails)
- Activity features (time between registration and first post, number of tags per post – spammers use more, …)
- Location features (number of users in the same domain or IP address)
- Semantic features (automatic tag from spamming software “$Group” can be used to make tags public in some bookmarking systems, blacklist of spam tags, co-occurrence of information as “a spammer shares resources with about 18 other spammers, but only with 0.5 non-spammers”)
The authors present a tool (SiteGuide) that supports amateur web-users to design web pages: Helping them to select and organize information for their pages. User input a set of example sites that are similar to their intended website. SiteGuide scrapes and analyses the sites and captures their commonalities in a web site model. From this, SiteGuide generates a site for the users. In addition, the system can provide the difference of a draft site of the user to its internal model of the example sites.
