The 2008 China International Industry Fair (CIF) was held from Nov. 4 to 8 at Shanghai New International Expo Centre (SNIEC), Shanghai. The delegation of IACAS joined this grand event. Two research results -- "Mobile Search Technology based on Natural Language Processing" and "High-directivity Audio Loudspeaker" developed by Institute of Acoustics were exhibited on the fair, which aroused the great interest of the visitors and got high praise from the leaders of CAS.

"Mobile Search Technology based on Natural Language Processing" is a kind of advanced technology, searching the target depending on the understanding of natural language included in the data-base. The users just need to send a question without uncertain form. The system will automatically find the answer and send it back to the user. Now the database included more than ten thousand pieces of message, including diet, accommodation, entertainment, travel, shopping, medical treatment and so on.

"High-directivity Audio Loudspeaker" is a novel loudspeaker which can generate an audio signal with high directivity by utilizing the parametric array principle. This loudspeaker is different from the traditional loudspeaker. The sound wave emitted by the high directivity loudspeaker can go along a certain direction. It can be used in sound directional propagation, secure communication and so on.
The China International Industry Fair began 10 years ago as a local industrial exhibition and has become an international event that showcases the highest levels of China's industrial developments.

Exhibits on display this year include the world's first floating crane, produced by Shanghai Zhenhua Port Machinery Co and capable of lifting 7,500 tons, and a hydraulic press produced by Shanghai Electric, which is the world's strongest - capable of exerting 16,500 tons of pressure. The event attracted 1,816 exhibitors, of which 473 are foreign companies.
