Automatic Categorization of Japanese Patents based on Surrogate Texts

This paper describes our work at the fifth NTCIR workshop on the subtask of patent classification. We use KNN (K-Nearest Neighbors) as our classifier and the English PAJ (Patent Abstract Japan) as the patent surrogate for classification. Based on the knowledge and experience learned from our previous experiments with other document collections, we leverage on the parameters to achieve above-ave...

Patents or Patents Pending

An Aluminum Nitride (AlN) MEMS resonator technology has been developed, enabling massively parallel filter and oscillator arrays on a single chip. Low loss filter banks and resonator arrays covering the 10MHz10GHz frequency range have been demonstrated, as has monolithic integration with inductors and CMOS circuitry. The high level of integration enables miniature multi-band, spectrally-aware a...
