Research on Vertical Search Method of Multidimensional Resources in English Discipline Based on Edge Computing

Abstract

The traditional vertical search method only considers the content of the webpage, and the global master node is not enough, which will lead to premature convergence and fall into the local optimum, resulting in insufficient multi-dimensional search of resources. Therefore, this paper proposes a multidimensional resource vertical edge based on the calculation of English subject search method. This paper analyzes the architecture of search engine firstly and then introduces the multiaccess edge computing architecture. At last, it constructs the vertical search task computing model of multidimensional resources in English discipline. By associating and traversing the attributes of multidimensional resources of English discipline, the vertical search of attribute information is realized offline, and the vertical search method of multidimensional resources of English discipline based on edge calculation is designed. In order to verify the effectiveness of the proposed method, a comparative experiment is designed. Experimental results show that the method can improve the resource search ratio and recall ratio, and it can also effectively improve the search efficiency. For an English subject resource data of 50 MB, the calculation methods of edge multidimensional resource data search recall rate can reach 97% and multidimensional resource data search time consumption is only 39 ms. The experimental results show that the performance of English subject multidimensional resources vertical search is much better.

Architecture, Technologies, and Applications of Location-Based Services

“…This special issue includes five papers on LBS for education which are listed as follows. LSB techniques were applied on vertical search methods [56], cloud classrooms [57], speech recognition [58], data stream classification [59], and online learning support service system based on LBS for providing education applications. Detailed information of each article on LBS for education could be found in [56][57][58][59][60].…”

Privacy retrieval method of big data in mobile network based on edge computing

“…There are still some deficiencies in functionality. On the one hand, most of the traditional privacy protection ciphertext query protocols are committed to resisting untrusted cloud attacks, and need to rely on privacy computing or trusted third parties to authenticate the legitimacy of users, lack of effective access control strategies, and the security needs to be strengthened [3]. On the other hand, most of the existing searchable encryption technologies are based on the design of tight cipher algorithm.…”
