摘要： 纷纷扰扰、立场各异的吴亦凡事件,以一种极具戏剧化的方式渐趋明朗。7月31日深夜,北京警方发布通报,加拿大籍男艺人吴亦凡因涉嫌强奸犯罪,被警方刑拘。随后几天,在公众怒火和媒体谴责的连番炮轰中,吴亦凡在娱乐圈的存在痕迹被一一抹除,就连搜索引擎上的相关介绍,也改成了“涉违法失德加拿大籍男艺人”,曾经支持他“睡粉”的六六、马薇薇等人亦先后被封号禁言。

关键词： big data   bivariate empirical mode decomposition   multiscale analysis   search engine data   tourist volume forecasting  

摘要： As helpful big data, search engine data (SED) regarding tourism-related factors have currently been introduced to tourist volume prediction, but they have been shown to impact the tourism market on different timescales (or frequency band). This study develops a novel forecasting method using an emerging multiscale analysis-bivariate empirical mode decomposition (BEMD)-to investigate multiscale relationships. Three major steps are performed: (1) SED process to construct an informative index from sufficient SED using statistical analyses, (2) multiscale analysis to extract scale-aligned common factors from the bivariate data of tourist volumes and SED using BEMD, and (3) tourist volume prediction using an SED-based index. In the empirical study, the novel BEMD-based method with SED is used to forecast the tourist volume of Hainan in China, a global tourist attraction, and significantly outperforms both popular techniques (not considering SED or multiscales) and similar variants (considering SED or multiscales) in accuracy and robustness.

关键词： colleges and universities   data mining   heterogeneous information   informatization   resource integration  

摘要： As far as the current higher education is concerned, the information system used in teaching and management is becoming more and more abundant, and the construction of its informatization is more and more rapid. However, the construction of university informatization project is too long, and there is no unified planning and other reasons, resulting in the difficulty of information and information management cannot be shared across departments. With the deepening of informationization and inaccurate information resources, how to use data mining technology to obtain valuable information is an important issue in the research of heterogeneous information in university management informationization. Based on the analysis of the information island problem in the informatization construction of colleges and universities, taking the student management work as a pilot, a heterogeneous information resource integration platform based on distributed query is proposed. Based on the platform, the information can be effectively applied globally. By analyzing its application in student information management, it shows that data mining is an effective technology to improve the management ability and scientific research level of colleges and universities in the construction of information technology.

摘要： Objectives: Patients navigating a new cancer diagnosis and the complex experience of cancer treatment may turn to internet-based resources and social media (SM) for information and support. To understand how gynecologic oncology patients research diseases and providers, we surveyed patients on their internet and SM use. Methods: Institutional review board (IRB) exemption was obtained and informed consent was implied by participation in this anonymous survey. All new patients to the gynecologic oncology clinic at an academic cancer care center were invited to participate. A 20 question study-specific survey was developed which included a variety of different question formats. Baseline characteristics as well as use of SM, search engines, and online review sites to learn about their diagnosis and choose a provider/clinic were assessed. Results: Over a 3 month period, 241 new patients were seen at the clinic with 107 surveys completed (44% response rate). Most patients (68%) were over the age of 50. 78% of patients had at least one social media account, Facebook being the most common (84%). The majority of patients (81%) reported at least daily SM engagement. Only 17% of patients had ever completed an online physician review, while 35% reported having filled out a hospital-provided review. 84% of patients had used the internet to research a medical condition before and 62% had used the internet or social media to research their current problem. The most common online resources were Google (70%), WebMD (35%), American Cancer Society (34%), other medical institutions (26%) and our own website (22%). Only three patients used SM as a resource to obtain information about their disease. With regard to provider choice, 39% of patients did not research their provider prior to their visit. Among those that did, 54% talked to their referring provider, 49% reviewed provider profiles on our website, and 35% used a search engine. A total of 45% felt they would be swayed towards or
