Abstract:
According to the present invention, a method for searching for information using the Web and a method for voice conversation using same involve generating a basic word vector for at least one of a provided user query and a language analysis result; usng the basic word vector, searching a vector space database for a vector space corresponding to the basic word vector; searching, if a similarity between the basic word vector and the found vector space is lower than a preset reference, a vector space database for a vector space corresponding to an expanded word vector using the expanded word vector generated from the result of the Web search performed using at least one of the user query and the language analysis result; and searching for knowledge information on the basis of the vector space found in the basic searching step or the expanded searching step. Thus, improved research results may be provided in response to the user query.
Abstract:
The present invention relates to a vehicle body height multi-control apparatus for an air suspension system, wherein an air spring is interposed between a vehicle body and a suspension arm to control the vehicle body height by the injection and discharge of compressed air. The vehicle body height control apparatus comprises: a mechanical leveling valve which rotates in the forward and reverse directions and the upward and downward directions, or in the left and right directions, so as to control the injection and discharge of the compressed air; a valve driver which drives the leveling valve in the direction of the injection and discharge of the compressed air; and a controller which controls the operation of the valve driver. Thus, an inexpensive vehicle body height multi-control apparatus for an air suspension system, which has a simple structure to enable a user to freely control the vehicle body height as needed, is provided.
