The document discusses the key challenges of semantic integration to enable the Internet of Things. Specifically, it addresses the difficulties of storing and querying large volumes of dynamic sensor data at scale, developing semantic models for sensors and sensor data, achieving interoperability across domain-specific semantics, and integrating sensor information with social semantic spaces. Overcoming these challenges would allow sensor data to be queried and analyzed like a database, with the world functioning as an integrated knowledge base.
IoT special session 2009
- 1. Mirko Presser CCSR, University of Surrey Guildford, United Kingdom Trends and Promises The Internet of Things Get Real! Go Semantics! In collaboration with Manfred Hauswirth
- 2. 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 Toms House by Postman Pat 5 hours ago from Parcel to Twitter event (pick-up) *Julian Bleecker, Near Future Laboratory *blogjects
- 3. Parcel: Tom_to_Tim I am lonely too =( 2 minutes ago from Letter to Parcel response to mission status 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, I am 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) *blogjects *Julian Bleecker, Near Future Laboratory
- 4. Parcel: Tom_to_Tim Where do you have to go? Tims place by any chance? 1 minutes ago from Parcel to Letter object cooperation I am lonely too =( 2 minutes ago from Letter to Parcel response to mission status 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!

- 5. Parcel: Tom_to_Tim Yes! Lets find someone to take us. 1 second ago from Letter to Parcel and Central Distributions self-X Where do have to go? Tims place? 1 minutes ago from Parcel to Letter object cooperation I am lonely too =( 2 minutes ago from Letter to Parcel response to mission status 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.

- 6. We are dealing with several domains ≒ User (Sender/Receiver) domain Twitter human readable text ≒ Object domain Machine interpretable data Sensor data not damaged, wrong pick-up, Mission progress distance to Tom ≒ Application (Postal Service) domain Application interpretable data Mission progress location (postal service) ≒ Application (Customer Service) domain Application and human interpretable data Efficiency dropped, delayed,
- 7. 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 Semantic Integration Physical World Cyberspace KnowledgeSemantic Integration Communities
- 8. 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
- 10. Semantic Integration Middleware Middleware Middleware 10101010 10101010 10101010 I am a parcel for Tom, dropped once I am TWITTER I am a Post van, not going to Tom
- 11. Semantic Integration Middleware Middleware Middleware Semantic Semantic Semantic Mash-up of Real World Knowledge Description Discovery Integration Distributed processing
- 12. 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 Reasoning upon the data The World at your Fingertips The world is the knowledge base
- 13. 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
- 14. Conclusions ≒ Tags/Sensors/Actuators are a global trend information explosion ≒ IoT + Semantic Web 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
- 15. 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. Thank You
