In recent years, due to the explosive growth of social media information, mining hot information in social media has become a research direction of great concern. In this paper, Python crawler technology is used to crawl the semi-structured text data of food safety news from static web pages and dynamic web pages. After preprocessing, the structured text data required to establish a document clustering algorithm (CASC) based on a convolutional neural network is obtained. Using the feature extraction ability of convolutional neural network and self-encoder, while preserving the internal structure of the original data to the greatest extent, it is embedded into the low-dimensional potential space for clustering. Finally, it is compared with the performance of the K-means algorithm and spectral clustering algorithm. The experimental results show that the CASC algorithm reduces the running time and time complexity of the algorithm on the premise of ensuring clustering accuracy. The CASC algorithm is superior to the k-means algorithm and spectral clustering algorithm in precision, recall, and composite index. At the same time, the running time is 91 seconds faster than the K-Means algorithm and 5 seconds faster than the spectral clustering algorithm.

“…During the launch and deployment process of the flexible web, the current verification test net size is relatively small, the flight range is close, and the intercept and capture target is mainly stationary or at low speed. [19,20] The simulation and verification tests of the new symmetrical structure flexible web make up for the above shortcomings and provide a new idea for the research. During the test, the flight height can reach tens of meters and the opening area can reach about 20 square meters.…”

A new type of flexible web with a spatial symmetry structure is proposed to address the interception and acquisition of UAVs. It is different from the existing flexible web structure. According to the mechanical characteristics of the flexible web, the dynamic analysis model of the flexible web is established through theoretical deduction. Through finite element simulation calculation, the flexible webs of three different spatial symmetric structures are compared and analyzed. The internal force and air attitude of the three flexible webs are discussed. Among them, the new flexible web has a lag time of 0.162 s and a flight height of 11.624 m. The above simulation parameters are better than those of the other two symmetrical structures. It was proved that the new spatial symmetric flexible web has good traction and deployment performance. In addition, a ground verification test is designed and carried out. The web attitude and flight altitude parameters are compared with the simulation and test results. It is found that the simulation and experimental process of the new symmetric structure web are in good agreement, the synchronization of attitude change is good, and the flight altitude error of the two is controlled at about 5%. The feasibility and effectiveness of this method are proven and it can provide a reference for the research of flexible interception and acquisition of UAVs.
