Parcel: Tom_to_Tim
I am lonely… =( 5 minutes ago from Parcel to Twitter mission status update Postman Bill unloaded me, but I am now sitting in the middle of the warehouse. HELP! 1 hours and 30 minutes ago from Parcel to Twitter request (help) Hey! Postman Bill! you should not pick me up, Tim is not on your route 2 hours ago from Parcel to Twitter and Postman Bill interaction with the real world I have arrived at central distributions, and have been filed for pick up 3 hours ago from Parcel to Twitter event (location, mission progress) Postman Pat dropped me on the way to the Van, but I was not damaged 4 hours 50 minutes ago from Parcel to Twitter event (drop) Picked up at Tom’s House by Postman Pat 5 hours ago from Parcel to Twitter event (pick-up)

Where do you have to go? Tim’s place by any chance? 1 minutes ago from Parcel to Letter object cooperation

Yes! Let’s find someone to take us. 1 second ago from Letter to Parcel and Central Distributions self-X

We are dealing with several domains…
• User (Sender/Receiver) domain – Twitter human readable text
• Object domain – Machine interpretable data – Sensor data à not damaged, wrong pick-up, … – Mission progress à distance to Tom
• Application (Postal Service) domain – Application interpretable data – Mission progress à location (postal service)
• Application (Customer Service) domain – Application and human interpretable data – Efficiency à dropped, delayed, …
Bridging the Gap
Making sensor-generated information usable as a new and key source of knowledge will require their integration into the (existing) information space of Communities à Semantic Integration

Communities
Semantic Integration
• Semantics allows you to create reusable knowledge that helps to – understand who is talking to who – who is doing what – and what the information means
• This enables the integration of information as knowledge
• On a large scale this machine interpretable information is a key enabler and a necessity for the IoT

Description Discovery Integration Distributed processing
Despite Data Volume, Heterogeneity, Distribution, Dynamics: We dream to use all that data like a database!
1. Structured Querying 2. Integrated Views 3. Aggregation, Analyses à Reasoning upon the data
The World at your Fingertips
The world is the knowledge base
Key Challenges – Semantics • Where are we?
– The core technological building blocks are now in place and (widely) available: ontology languages, flexible storage and querying facilities, reasoning engines, etc.
– Standards and guidelines for best practice are being formulated and disseminated by e.g. the W3C.
• What is still difficult?
– Scale and time dependency of data • Storage and Querying of Masses of Dynamic Information
– What do we want to explain by semantics • Semantic modelling of sensors and sensor data
– How to create useful descriptions without modelling the whole universe
• Interoperability of domain specific semantics • Integration with Social Semantic Information Spaces
Conclusions
• Tags/Sensors/Actuators are a global trend à information explosion
• IoT + Semantic Web à Integrated information space
• Collaboration across domains and disciplines is essential – Future Internet Assembly
• Networked Knowledge • Network Architecture • Device Technologies • Security, Privacy and Trust • Application domains
Gartner: „By 2015, wirelessly networked sensors in everything we own will form a new Web. But it will only be of value if the ‘terabyte torrent’ of data it generates can be collected, analyzed and interpreted.”
