Publication number: 20190155851Abstract: This application discloses an information filtering method and an information processing apparatus. Shared information that is shared by a user account of an online service is obtained. A credibility reference rating associated with the user account is obtained. The credibility reference rating indicates account credibility of the user account. Whether the shared information satisfies a filtering condition is determined based on the credibility reference rating. Further, the shared information is filtered when the shared information is determined to satisfy the filtering condition.Type: ApplicationFiled: January 29, 2019Publication date: May 23, 2019Applicant: TENCENT TECHNOLOGY (SHENZHEN) COMPANY LIMITEDInventors: Xingya WANG, Qian Chen, Boen Liang, Jinzheng Zhang, Jianwei Yuan, Leming Fang, Chao Wan, Jilan Liang, Zijian He, Rui Tang, Zhike Liang, Xin Huang, Huankun Huang, Haixia Rao, Junwei Shen, Jun Zhang, Shuqin Sun, Pengfei Wang, Yingchao Liu, Wa Ye, Fei Huang, Jiasheng Huang, Zheqi Feng, Luting Chen, Shuwen Hu, Lingyun Xu

Patent number: 8753599Abstract: A method and composition for the reduction of the emission of selenium into the environment from the burning of fossil fuels with the use of two chemistries, either individually or in combination with each other. The method uses polydithiocarbamic compounds, including polydithiocarbamic compounds derived from a polymer produced from acrylic-x and alkylamine in conjunction with a scrubber process to capture selenium and reduce its emission in aqueous phase blowdown. The method and composition also helps reduce corrosion in the scrubber process.Type: GrantFiled: February 6, 2012Date of Patent: June 17, 2014Assignee: Nalco CompanyInventors: Bruce A.
