Deep Learning in Computational Linguistics for Chinese Language Translation

Abstract

Applying Artificial Intelligence to Chinese language translation in CL (Computational Linguistics) is of practical significance for economic boosts and cultural exchanges. In the present work, the Bi-directional Long Short-Term Memory (BiLSTM) network is employed to extract Chinese text features regarding the overlapping semantic roles in Chinese language translation and hard-to-converge training of high-dimensional text word vectors in text classification during translation. Besides, the AlexNet is optimized to extract the local features of the text and meanwhile update and learn network parameters in the deep network. Then, the attention mechanism is introduced to build a forecasting algorithm of Chinese language translation based on BiLSTM and improved AlexNet. At last, the forecasting algorithm is simulated to validate its performance. Some state-of-art algorithms are selected for a comparative experiment, including Long Short-Term Memory, Regions with Convolutional Neural Networks features, AlexNet, and Support Vector Machine. Results demonstrate that the forecasting algorithm proposed here can achieve a feature identification accuracy of 90.55%, at least an improvement of 4.24% over other algorithms. Besides, it provides an Area Under the Curve of above 90%, a training duration of about 54.21s, and a test duration of about 19.07s. Regarding the performance of Chinese language translation, the algorithm proposed here provides a Bilingual Evaluation Understudy (BLEU) value of 28.21 on the training set, with a Performance Gain Ratio (PGR) reaching 111.55%; on the test set, its BLEU reaches 40.45, with a PGR of 129.80%. Hence, this forecasting algorithm is notably superior to other algorithms, which can enhance the machine translation performance. Through experiments, the Chinese language translation algorithm constructed here improves translation performance while ensuring a high correct identification rate, providing experimental references for the later intelligent development of Chinese language translation in CL.
