What I have done:

• III Proposal (Collaboration with Hsiao-wei, David, Yu-chin and Wan-rong.) We finished the III proposal about taxi hot spot prediction, and also revised it based on the review result from III.
• AI TA Work I graded MSRS task 2 and term project source code together with Tsu-yu, and created the archive CD for the department office.
• AAMAS Workshop Paper (Collaboration with Yuhana, Wan-rong and Joe.) I joined the discussion about paper outline and content, provided opinions to revise the problem definition, and edited/revised the chapter of introduction, background technology and related work. This paper editing is still on-going, and we expect to submit the paper by Feb. 8.
• Android Developer Challenge (Collaboration with David and Hsiao-wei.) We started discussion about the topic, and we decided to create an application combining the elements of city guidance and urban games. The idea is to provide users a city guidance service to travel in an area, using games as a motivation to have people enjoy. The system first designs a tour path and spots for the user considering the context information. When users arrive the spot, like REXplorer[3] and Snap2Play[5], a specific game which has some connections with the context will be given to the users. We have thinked about using ontology to model the time and location context, game attributes and user experience, and using reasoning to suggest the proper game for one spot and the next destination. However, to minimize the effort and meet the deadline, we will just create a prototype with all information fixed for idea demonstration purpose.
• Course Term Projects
• Paper Survey
  • Ontology SOUPA[4] is a well-known upper ontology for pervasive computing and context-aware systems. It defines (or modifies from other work) time, space, event, and some other core ontologies, and creates a context broker architecture (CoBrA) and two small scenarios to demonstrate the power of ontologies. It is an innovative work to create the ontologies to model context, and we can adjust their ontologies to meet our demand.
  • Geo-spatial Model Ye et al.[10] designs a more general space model to deal with both syntatic/semantic label and geographic position, both resolute referencing and relative referencing, and both containment and connection properties. I have to say that they do consider more aspects of describing geo-spatial information than other work, and this model seems more powerful to deal with different kinds of location representations and to provide services.
  • Navigation Systems To write the related work of the AAMAS Workshop paper, I quickly skimmed through several papers[1, 2, 8, 9].

What I plan to do.

• AAMAS Workshop Paper Finish editing the paper and submit before the due date.
• CA Group Think of one location-aware service, and create a small ontology for the scenario.
• Android Developer Challenge Pick one city tour itinerary, collect relevant photos and descriptions, and design games for introducing the spot. These will become part of the demonstration content of our prototype.
• Paper Survey
  • Spatial Queries Using geographical ontology for spatial queries[6, 7] is one part of SPIRIT Project. I think spatial queries and spatial indexing problems are very alike, and I hope I can find something from their work.
  • Mobile Urban Games REXplorer[3] and Snap2Play[5] introduce two kind of mobile urban games, and I hope I can find some more examples or ideas from their related work.
