Our Work: A People Centric Perspective
• One important (maybe the most important ) feature of a smart city is that:
– people living in the city is well taken care of
– people’s life in the city is easy and convenient
• A smart city must have rich and well organized apps to help the residents to ease their lives, including: birth, education, medical services, transportation, job finding, entertainment, shopping, paying tax…
Applications that used by residents to help them make their lives more convenient or efficient are referred as People-centric Apps
How To Build Those People-centric Apps
• Requirements and Challenges
– Have complex domain knowledge
– Be creative
– Be agile
– Provide highly personalized services
– Access the data or functionality of other systems
– Manage enormous concurrent access
– Provide services through different devices
– Organize (governance,classify, recommend) these apps
– …
The best solution might be:
building an open platform, aggregating all kinds of resources,
and encouraging everyone to participate

1) Core Ontology Built by domain experts based on the construction of smart cities via
centralized ways Refine the high-level , stable and general domain concepts and their
relationships to support the requirements of self-growth and self-evolution of the model
Provide the common basis for different cities to build localization domain model and interconnect each other
2 ） Collaborative Ontology Editor
Graphical browsing and editing for domain ontology Management of personal workspace Iterative domain ontology evolution and release
management
3) Internet based Knowledge discovery Based on active iterative method, automatically mining the related
concepts of seed from Internet according to the user's seed term. Processing and storing the results of mining as ontology concepts.
