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. Keywords— Spamming behavior, spamming store, detection method 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. He had been working as an Assistant or Lecturer in Weifang University of Science & Technology, China from 2005 to 2015. Currently he is a doctoral candidate in machine learning at Dongseo University, Korea. His research interests include machine learning, data mining, spam review detection.

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

The influence of the thickness of ice film on the response of the QCM was investigated by an impedance analysis method. It is shown that part of freshly prepared amorphous ice film on QCM is disappeared gradually during a stimulant convection process at -18 C. We report a mulriple resonance phenomenon in QCM with unsymmetrical mass loading. The shape of the conductance- frequency spectrum of QCM depends on the thickness and distribution of the ice film deposited. After adsorption of ethanol vapor, the rigidity of the ice film is decreased gradually.
