Context of Project

How much we can be inspired … by the objects around us?


Context: ubiquitous learning Learning from things around us

Objects are linked by Linked Data CDIO model

(Conceive-Design-Implement-Operate)

Context is as important as Content

CONTEXT:

Information relevant to Object.

Information relevant to User.

Historical activities of User

Relevant resource


IDEA Building

IoT model1. Objects are linked.2. Users take advantage from the information ubiquitous.

Use Case

How it works … with a Coffee Machine?


Exploitation of information?

Development & Implementation

Works on the model.



Technologies Chosen 1

Object URI : QR code QR Code Generator : Open Source QR Code Decoder : Specification for different mobile terminals.

Web Builder : PHP 5.2.9 MySQL 5.1.32 PHPMyAdmin 3.1.3 Apache2.2.11



Technologies Chosen 2

Data Management : RDF RDF editor. Resource query language: SPARQL Relationship Graph: DBpedia Relation Finder RDF file query: RAP API Semantic Web Application: MeaningTool



Summary of 1st step implementation

Implementation Link objects to URI Structure data Present readable RDF data on web page Query to RDF file with PHP

Difficulties have been met Had troubles when used some libraries for RAP

API program. (ex. infModel) Schema can not be expanded in Isparql Need more specifications for further development.



Future Desire

Modeling data “Model Driven Data” : Data should be used for model application. Data should be enriched for the use case.

Indexing data and services Combined with context awareness, propose the

most appropriate data and services. User context need to be proceeded for the use

case.



Demonstration

Educational Internet of Things



Conclusion

What I have learned.



Conclusion

Ubiquitous information satisfy curiosity. Power of data when they are linked. Standards are indispensable for universal communication within machines and people. But Currently, - Human is still needed for decision. - More data need to be structured. - Ecosystem of Semantic Web is under developed for its bright future.
