Abstract: A data searching method for a data dictionary, comprising obtaining an input word and performing a word embedding operation on the input word to generate a word vector of the input word, calculating a degree of correlation between the input word and a plurality of words in the data dictionary according to the word vector of the input word, and determining at least one recommendation synonym from the plurality of words in the data dictionary according to the degree of correlation between the input word and the plurality of words in the data dictionary, wherein the step including when determining that the cosine similarity between the word vector of the input word and a word vector of a first word of the plurality of words in the data dictionary is greater than a threshold value, determining the first word as a recommendation synonym.

Abstract: A semiconductor device includes a single diffusion break (SDB) structure dividing a fin-shaped structure into a first portion and a second portion, an isolation structure on the SDB structure, a first spacer adjacent to the isolation structure, a metal gate adjacent to the isolation structure, a shallow trench isolation (STI around the fin-shaped structure, and a second isolation structure on the STI. Preferably, a top surface of the first spacer is lower than a top surface of the isolation structure and a bottom surface of the first spacer is lower than a bottom surface of the metal gate.

Abstract: A control device and a method of stopping the spindle motor or an optical disc system. The control device primarily includes an optical disc control chip, a motor driving circuit and a spindle motor. The optical disc control chip generates and delivers a spindle motor control signal to the motor driving circuit for driving the spindle motor into rotation. During a first period, the spindle motor control signal level is controlled to produce the largest reversing torque permitted by the spindle motor for braking purpose. During a second period, the spindle motor control signal level decreases gradually to approach to a lock level that is smaller than that for actuating the spindle motor, so that the reversing torque is also decreasing gradually.
