A Pattern Science for the Semantic Web
I will present the current state of play with respect to collecting, finding, classifying, and using (design) patterns on the semantic web. The talk will compare historically related work, highlight some successful stories and curious unexpected bottlenecks, and will envision some charming research and development directions from the Web of Data.

From Disasters to WoW: Using Web Science to understand and enable 21st century multidimensional networks
Recent advances in Web Science provide comprehensive digital traces of social actions, interactions, and transactions. These data provide an unprecedented exploratorium to model the socio-technical motivations for creating, maintaining, dissolving, and reconstituting multidimensional social networks. Multidimensional networks include multiple types of nodes (people, documents, datasets, tags, etc.) and multiple types of relationships (co-authorship, citation, web links, etc). Using examples from research in a wide range of activities such as disaster response, public health and massively multiplayer online games (WoW - the World of Warcraft), Contractor will argue that Web Science serves as the foundation for the development of theories and methods to help advance our ability to understand and enable multidimensional networks.

SKOS: Past, Present and Future
SKOS (Simple Knowledge Organisation System) is a common data model for sharing and linking knowledge organization systems via the Web. Many knowledge organization systems, such as thesauri, taxonomies, classification schemes and subject heading systems, share a similar structure, and are used in similar applications. SKOS captures much of this similarity and makes it explicit, enabling data and technology sharing across diverse applications.
The SKOS data model provides a standard, low-cost migration path for porting existing knowledge organization systems to the Semantic Web. SKOS also provides a light weight, intuitive language for developing and sharing new knowledge organization systems. It may be used on its own, or in combination with formal knowledge representation languages such as the Web Ontology language (OWL). SKOS was published as a W3C Recommendation in August 2009 and is seeing growing take-up in a number of fields including (among others) cultural heritage, economics, astronomy, and local government. SKOS also looks set to play a key role in providing vocabularies for the Data Web through its use in Open Linked Data.

The Semantic Product Memory: An Interactive Black Box for Smart Objects
A semantic product memory stores a diary of an individual physical object in a persistent way on an embedded sensor system that is networked by wireless communication to a smart environment. The product monitors itself and its environment. Semantic technologies based on OWL ontologies guarantee interoperability of the product memory across the complete supply chain and lifecycle of smart objects and enable end user access to the product’s lifelog.
In this talk, we present the layered architecture together with the representation and inference formalisms used in our SemProM project, funded by the German Ministry of Education and Research (BMBF) with 16 Million Euro. SemProM goes well beyond traditional RFID technology and is the basis for intelligent automation in smart factories, event-driven logistics as well as smart retail and after-sales. Collecting information logs about objects in such smart environments and making it available - for example about an object’s origin, location, movements, physical properties, environmental conditions, usage history, as well as warranty and maintenance data - can help enterprises to improve their business processes and create new ones. Existing business process models become more accurate since information taken directly from the point of action can be used to manage or adapt processes in real time for the emerging Internet of Things.
We show how such embedded “black box” event recorders can transform everyday objects like cars, circuit boards, pizzas and drug blister packs into smart products. We show how consumers of smart products can access the lifelogs of products by NFC-enabled smartphones using SemProM’s browser and track the complete history of a product in multimodal dialogues. A role-based access control mechanism ensures privacy and security of the SemProM product memories. We will discuss fully operational pilot implementations of semantic product memories developed in the SemProM consortium together with major German companies like SAP, BMW, Siemens, DHL, Globus Retail and Kohl Pharma.
