Web ScienceWeb Science Trans-disciplinary field of Science taking the Web as its primary object of studyWeb Science invests Statistics of the Web Mathematical Modeling of the Web Bio-medical Networks Semantic Processing Economic Analysis of the Web business Behavioral Analysis of Web users
MSc Program in Web ScienceGoal multi-disciplinary approach although oriented towards the Statistics and Mathematics of the Web. Understand and model how the Web works and evolves in the knowledge society.Study base Web assessment, Mathematical Modeling and Operation combined with Business Applications Societal Transformations
Semantic Wikias Learning Management System• Wikis as Learning Management Systems has been explored.• Learning Management Systems integration with Semantic Web is on the way.

MSc in Web Science Program Semantic Wiki (WSSW)
WSSW implementation Engine Most Important Extensions• Apache 2.2.11 • SMW 1.4.3 • SMW Halo 1.4.6• PHP 5.2.9 • Semantic Forms 1.9 • Semantic Gardening 1.3• MySQL 5.1.33 • Semantic TreeView 1.2• MediaWiki 1.15.3 • Semantic Result Formats 1.4.5 • WYSIWYG FCK 2.6.4 • SMW User Manual 1.0 • Semantic Maps 0.5.5 • Semantic Rule Extension 1.0Embedding the semantic webtechnologies • Halo ACL 1.1.1_0Facilitate the use of Semantic Wiki • Confirm User Accounts 1.46for a large community of users, • Password Reset 1.7especially those who are notfamiliar with semantic annotations
WSSW ontologyReuse of existing ontology standards: FOAF describes the academic staff and the studentsReuse of already defined ontologies: Master Ontology the best ontology model for master program implemented by MSc’s students
Snapshots from Web Science Semantic Wiki (WSSW)
Critic - Conclusions• Halo extension constrains the WSSW, and in general the implemented wiki, to use only its data.• No external endpoint can be called to import the query’s results in WSSW pages.
Future Work ImplementationUse SPARQLExtension as soon as it is stable to call external endpoints.Move to LinkedWiki or other extension which implements queries to external endpoints and embeds them in wiki’s pages!Embed content derived as SPARQL queries to WSSW’s pages from related external endpoints.
Future WorkUse Semantic Signup extension to semantically annotate every new user!Annotate courses and the educational objects they provide using the proper codes from the corresponding Scientific Classifications in SKOS format. ACM Classification Mathematics Subject Classification
