In view of the phenomenon of noun coreference in Chinese, This paper proposes a deep learning mechanism based on Conditional Random Field (CRF) to study coreference resolution based on deep semantic information representation. The text is input into the vector of Biditive Encoder Representations from Transformers model. The self-attention mechanism is used to mine the hidden features at the context semantic level. Through the reasoning ability of CRF, the complex features are used for reasoning training, and the training results are scored and classified by softmax to complete the anaphora resolution task. The experimental results show that the performance of coreference resolution can be effectively improved by making full use of text feature representation.

To make good use of the ocean, we must know enough about it. Supported by the Ministry of science and technology of China, the marine physical parameters monitor is developed to obtain real-time marine physical parameters such as temperature, humidity, pressure, rainfall, wind speed, wind direction, solar radiation, water depth, salinity, conductivity and other data. The integrated intelligent service software platform for marine physical property monitoring data is used for real-time collection, storage, historical data analysis, integrated display and other work of these data. As a part of the integrated intelligent service software platform, an improved big data quality control method which comprehensively uses the meteorological industry standards test, least square polynomial fitting, multiple regression and other technologies is proposed in this paper to improve the correct and efficient use of these real-time or historical data in terms of data inspection, correction, reconstruction and quality evaluation, etc. The existing historical data prove the effectiveness of this method.

In view of the practical problems such as the imperfect harmonic testing and evaluation methods of the variable frequency speed regulation system and the high operating cost, a harmonic evaluation index system including 9 indexes is established, and the calculation method of each index is clarified. At the same time, the harmonic testing and analysis method of the variable frequency speed regulation system based on virtual instruments is proposed. The Labview software platform is combined with an external data acquisition module to replace the traditional testing instruments for harmonic testing and signal acquisition, processing and analysis. On the basis of theoretical research, an experimental platform was built to conduct verification experiments, and then the application experiments of 2 working conditions were carried out. The results shows that the test method was correct and feasible. Based on the experimental results, further analysis of the impact of harmonics on the performance of the variable frequency speed control system, and the corresponding law of influence will be obtained, which will provide guidance for the subsequent development of harmonic prevention and other related work.

The ever-increasing penetration of wind power has resulted in new problems and challenges to the secure and economic operation of the power system concerned. Given this background, a bi-level transmission system planning model for this purpose is proposed. In the upper level, the objective is to minimize the total cost, the attained transmission planning scheme will be transferred to the lower level. In the lower level, the objective is to minimize the sum of the discharge cost of the energy storage system and the cost of abandoning the wind farm, the discharge cost of the energy storage system and the cost of abandoning the wind farm are transferred to the upper level as feedback. These two levels are implemented interactively and iteratively. Finally, the essential features of the developed model and adopted algorithms are demonstrated by a modified 18-bus test system.
