The application discloses a method for correcting term mistranslation in a translation. The correction method includes the following steps: obtaining an original translated text of target terms in a first translation, obtaining candidate translations corresponding to the target terms from a training set, and setting all the candidate translations to pseudo-translated texts; replacing the originaltranslated text in the first translation with each of the pseudo-translated texts respectively to obtain N second translations, and performing a back-translation operation on the first translation andall the second translations to obtain N+1 back-translated texts; and performing text comparison on a source text and all the back-translated texts to determine the translation accuracy of the first translation, and correcting the original translated text of the target terms according to the translation accuracy. The method can implement the mistranslation correction of domain-specific terms in the machine translation without relying on a large amount of resources in the field. The application also discloses a system for correcting term mistranslation in the translation, a computer readable storage medium and a device for correcting term mistranslation in the translation, which have the above beneficial effects.

A first speech processing device includes a first speech input unit and a first speech output unit. A second speech processing device includes a second speech input unit and a second speech output unit. In a server therebetween, a speech of a first language sent from the first speech input unit is recognized. The speech recognition result is translated into a second language. The translation result is back translated into the first language. A first speech synthesis signal of the back translation result is sent to the first speech output unit. A second speech synthesis signal of the translation result is sent to the second speech output unit. Duration of the second speech synthesis signal or the first speech synthesis signal is measured. The first speech synthesis signal and the second speech synthesis signal are outputted by synchronizing a start time and an end time thereof, based on the duration.

The invention relates to a flue gas analysis device based on an ultraviolet difference technology, and a flue gas analysis method. The flue gas analysis device sequentially comprises an ultraviolet light source, a measuring cell, an optical fiber and a spectrograph, wherein a focusing lens and an optical fiber connection adjustment mechanism are arranged at the end, close to the optical fiber, of the measuring cell; the optical fiber connection adjustment mechanism is used for adjusting the front and back translation, relative to the measuring cell, of a longitudinal end face of the optical fiber so as to utilize the axial chromatic aberration of the focusing lens to enable ultraviolet light emitted by the ultraviolet light source to couple different spectral energy distributions in the optical fiber, thus obtaining the position of the longitudinal end face of the optical fiber with the maximum spectral energy distribution at the absorption wavelengths of all flue gas components by means of multiple adjustments during detection, improving the signal to noise ratio and enhancing the detection sensitivity of concentrations of all the flue gas components. The device and the method can adapt to detection of different sample gases to be detected.

The invention discloses a data enhancement method based on adversarial training in a text classification scene, which comprises the following steps of: translating an original sample xi in a training set back to generate a sample sequence set D '= {x'i, y'i} 1... N; performing a word embedding process on the paraphrasing sample x'i to obtain p theta (x'i); carrying out adversarial training on the paraphrase sample x'i to obtain an adversarial sample original sample xi, carrying out a word embedding process to obtain p theta (xi), and carrying out a word embedding process of adding disturbance on the adversarial sample to obtain comparison loss of the original sample and the adversarial sample through calculation; and if the comparison loss obtained by calculation meets a preset threshold range, adding the generated adversarial sample into the original data set, and sending the adversarial sample and the original data set to a classification model for simulation to obtain a simulation classification accuracy result. According to the method, adversarial training is combined with data enhancement technologies such as back translation, random noise injection, cross enhancement and the like, so that enhanced samples with the highest quality and the highest diversity are obtained.
