1 Detecting the Spam Review Using Tri-training Ji Chengzhang*, Dae-Ki Kang** *Weifang University of Science & Technology, Weifang 262700, China **Dongseo University, 47 Churye Ro, Sasang-Gu, Busan 617-716, Republic of Korea [email protected], [email protected] Abstract— Some supervised learning methods were developed to detect spam review and some of them are considerably effective. Some researchers also find that the review spammer consistently produce spam reviews. We observe that the spamming store also consistently produce spam reviews. This provides us two other views to identify review spam: we can identify if the reviewer is spammer and if the store is spamming one. We introduce a three-view semi-supervised method, tri-training, to exploit the large amount of unlabeled data. The experiment results demonstrate that three-view tri-training algorithm can achieve better results than two-view co-training and single-view algorithm. Keywords— Deceptive reviews, semi-supervised learning, supervised learning, tri-training Ji Chengzhang He received the B.S. degree in computer science and technology from Linyi University, Linyi, Shandong Province, China in 2005, and received the M.S. degree in computer application technology from Ocean University of China, Qingdao, Shandong Province, China in 2010.

How to Infuse Yimeng Revolutionary Spirit Into Moral Education in Primary School in Shandong Province: Text Analysis Based on Of
2020 2nd International Conference on Education, Economics and Information Management (EEIM 2020) ISBN: 978-1-60595-684-8 How to Infuse Yimeng Revolutionary Spirit into Moral Education in Primary School in Shandong Province: Text Analysis Based on Official Website of Educational Administration Ji-lin ZOU1,a, Cheng-yan YANG1,b,* and Wen-hui LI1,c 1School of Education, Linyi University, Linyi, Shandong, China [email protected], [email protected], [email protected] *Corresponding author Keywords: Yimeng Revolutionary Spirit, Moral Education, Text Analysis. Abstract. Many researchers have emphasized the role of Yimeng Revolutionary Spirit in the development of primary school students’ moral behaviors and beliefs. Some primary schools have already carried out a lot of moral education activities involving Yimeng Revolutionary Spirit. However, previous researches mostly used the methodology of theoretical reflection. In contrast, our study used a qualitative method called text analysis, which encoding news content published on official website of educational administration in Shandong Province. Results indicated that there are some problems in moral education activities involving Yimeng Revolutionary Spirit. For example, many cities have not enough attention from government official, and insufficient parent participation, insufficient curriculum resource development, and loss of campus culture. These social, family and school factors above are analyzed in details. Lastly, we proposed four targeted and specific solutions to improve the

Detecting Spamming Stores by Analyzing Their Suspicious Behaviors
1 Detecting Spamming Stores by Analyzing Their Suspicious Behaviors Ji Chengzhang*, Dae-Ki Kang** *Weifang University of Science & Technology, Weifang 262700, China **Dongseo University, 47 Churye Ro, Sasang-Gu, Busan 617-716, Republic of Korea [email protected], [email protected] Abstract— The purpose of this paper is to detect the stores with spamming behaviors. We identify suspicious behaviors of these stores to detect spamming stores. These suspicious behaviors are from the two following observations. First, spamming stores may target quantity of sale and product reviews to influence consumers' decisions. Second, they tend to deviate from the other stores in quantity of the sale and reviews. From those observations, we propose a novel scoring methods to find spamming stores, and they are applied on AliExpress dataset. Our experiment results show that our proposed methods are effective in finding spamming stores.

The Development of Local Music in Southern Shandong Province
Advances in Computer Science Research, volume 83 8th International Conference on Social Network, Communication and Education (SNCE 2018) The Development of Local Music in Southern Shandong Province under the background of Massive Open Online Course Qingpeng Huang College of Music and Dance, Zaozhuang University, Zaozhuang, Shandong Province 277160,China [email protected] Keywords: Massive open online course; Southern Shandong local music; Inheritance; Development Abstract. The unstoppable development of massive open online courses has brought new opportunities and challenges to the teaching mode of higher music education in our country and the inheritance and development of local music in southern Shandong Province. In this context, the reform of the teaching mode of the local traditional music course in southern Shandong Province to improve the teaching quality provides an opportunity for popularizing the local traditional music in southern Shandong Province. Introduction The music of southern Shandong Province has a long history and is also an integral part of the excellent culture of the Chinese nation. Over the past several thousand years, it has shown the obvious epoch imprint and rich cultural and historical details in the southern part of Shandong Province. "Sitting straight on his chair, clasping the mandarin duck board with left hand and striking it up and down among the fingers, and then jingling the mandarin duck to give a crisp sound, holding a drumstick with right hand, holding his breath and beating the drum three or five times, boom-bang-bang-bang bang, starting to talk about long-lost Lunan Dagu, the word is clear, the voice is vigorous..

Through detailed data, it analyzes the current status of colleges and universities that have offered non-common language majors in the province in terms of English curriculum setting, English ability cultivation and online classroom construction. In view of the existing problems, this paper puts forward some feasible suggestions on the English curriculum setting, talent training requirements and network classroom construction of non-common language majors, and hopes to make some beneficial exploration on the rationalization of English curriculum setting of colleges and universities in the province. Keywords: non-common language majors, college English, course setting I. INTRODUCTION University of Petroleum and Shandong Normal English has been widely recognized as a universal University, have also adopted this mode. language. In a broad sense, non-common language majors refers to majors other than English, such as In Shandong province, most of the colleges and Japanese, Korean, German, Arabic and so on. Non- universities open up English courses for students common language, in its narrow sense, refers to majoring in non-common languages majors , but the languages other than the working languages prescribed current English curriculum still faces big problems in by the United Nations (Jingsheng Lu, 2012) [1].
