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)

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.”
