By VOA News 01 May 2009 The number of confirmed cases of the H1N1 swine flu virus is rising worldwide -- with nearly all of Mexico, the epicenter of the outbreak, at a standstill in a bid to contain the illness.Mexico has confirmed 15 deaths from the virus It plans to make a research in a

limited domain, like food, text news, etc, aiming to improve the accuracy of the summarization by domain-specific knowledge and dynamic weight

Mexico has confirmed 15 deaths from the virus, but the suspected death toll there is more than 160. Mexican authorities report hundreds of additional cases. ………….

TG3: Collaborative LBS Technologygy

This research involves computer-aided collaborative work, context-aware computing and the processing and optimization of spatio-temporal data miningand optimization of spatio temporal data mining.

It mainly focus on the context data modeling in pervasive environment, and provide flexible and reusable data model so as to facilitate data management and share. g

It focuses on the processing and optimization of ti t l d t i bil i t th t ispatio-temporal data in mobile environments, that is,

to process and optimize users' queries while the possible routes of moving objects are uncertainty.

TG4: Privacy Control in Context-aware Technologyy gy

The privacy-protection in context-aware system will face new challenges: 1) It is difficult to develop an access control policy due to the large amount of information and the mobile users in the environment;amount of information and the mobile users in the environment;2) The restrictions on access and the cloaked data aiming to protect the privacy will inevitably lead to the unavailability of some context information.

We aim to design a expression for privacy control strategy in context to realize the simplification of privacy policy by the mapping fromto realize the simplification of privacy policy by the mapping from abstract policies to specific policies.

The research on context information privacy protection technology p y p gybases on the cloaking, mainly focusing on making a balance between privacy protection and information availability.
