摘要：collaborative work and social computing (cwsc) rely on the voluntary contributions from grassroots users, also known as user-generated content (ugc). cwsc developers tend to take the existence, availability, or sustainability of ugc for granted. the assumption is fueled by industry reports of massive user traffic. previous empirical studies reinforce the optimism. however, these results suffer from at least two problems: focusing on short-term or isolated from competitions. to obtain a more accurate and realistic knowledge of ugc, we need to examine not only loyal users, but also dropouts, switchers (who leave for alternative platforms), reactivated sleepers, and the transitions among them. i’ll illustrate the dynamic processes of ugc with several case studies of social media in china and elsewhere.

报告人简介：dr. weiming shen is a principal research officer at national research council canada. he is a fellow of canadian academy of engineering, fellow of engineering institute of canada (eic), fellow of ieee, and professional engineer of ontario (peo). he is an internationally-recognized expert on agent-based collaborative technologies and applications. he has published several books and over 450 papers in scientific journals and international conferences in the related areas. his work has been cited over 13,000 times with an h-index of 52. he served as a member of the steering committee for the ieee transactions on affective computing; editor-in-chief of the iet collaborative intelligent manufacturing; and an associate editor or editorial board member of over ten international journals (including ieee transactions on automation science and engineering; ieee transaction on smc: systems; ieee smc magazine; advanced engineering informatics; computational intelligence; intelligent buildings international; service computing and applications), and as guest editor for several other international journals.
摘要：industries and societies require new technologies to address increasingly complex design issues for products, structures, buildings, systems, processes, and services while meeting the high expectation of customers. computer supported collaborative work in design (cscwd) emerged in response to this requirement. with the rapid advancement of internet and web based technologies, cscwd has been a very active r&d area in the past two and half decades. recent developments of cloud/fog/edge computing, internet of things, big data, blockchains, and digital twin technologies have brought new opportunities for cscwd. this talk will presents a brief review of the 25-year history of cscwd and discusses future research opportunities and challenges.

from discovery to design: creating ai technologies to support massive-scale online collaboration
报告人简介：haiyi zhu is an assistant professor at the university of minnesota, twin cities. she will join human-computer interaction institute at carnegie mellon university as an assistant professor starting from september 2019. she holds a b.s in computer science from tsinghua university and an m.s. and a ph.d. in human-computer interaction from carnegie mellon university. she has received an nsf crii award as well as several paper awards in venues such as chi, cscw, and human factors, and an allen newell award for research excellence. she has also taken on major service roles in the community, serving as the secretary/treasurer of hcic, program committee members for chi and cscw, and the acting editor for an hci journal special issue on unifying ai and hci.
摘要：the development of internet technologies creates virtual spaces where people all over the world can interact around a shared purpose. internet-based platforms, such as wikipedia, facebook, airbnb, and uber, have transformed the way people connect, communicate, collaborate, work, and live. these platforms also enable collaboration and coordination at unprecedented scales. the english wikipedia alone, as of july 2017, has over 5 million encyclopedia articles, 2.9 million active editors, 38,628 new editors registering on the site in an average month, and about 160,000 new edits every day. in my research, i conduct two types of research activities: 1) “discovery” – i integrate different research methods, including machine learning, log data analysis, and controlled experiments, to produce a clear description and causal understanding of how activities are managed in large online platforms. 2) “design” – i combine an in-depth empirical understanding with design methods to create innovative ai technologies to support massive-scale collaboration on these platforms and evaluate their effectiveness and impacts in the real world. in this talk, i will illustrate my approaches to research, discuss my shift from discovery to design, and discuss my on-going work and future directions.

摘要：大数据问题所固有的规模繁杂性、高速增长性、形式多样性、价值密度低等特点为传统计算处理方法带来了严峻的挑战。一方面，大数据的规模繁杂性和高速增长性带来了海量计算分析的需求；另一方面，形式多样性和价值密度低等特点使得大数据计算任务高度依赖复杂认知推理技术。针对大数据计算中海量计算分析和复杂认知推理需求并存的技术挑战，基于人机协作的群体计算是有效的解决途径。大数据群体计算是一种新型计算模型，其目的是通过整合互联网上大量用户和计算资源来处理现有计算技术难以解决的大数据问题。本报告将介绍大数据群体计算的研究现状，面临的挑战以及发展趋势，特别是介绍人机协作的群体计算模型、质量感知的群体计算方法以及资源可控的群体计算机理等方面最新研究成果。
