超越用户需求 —以内容理解为导向构建推荐系统

作者:IVETA HAJDAKOVA, Stripe Partners; DEB MCDONALD, Spotify; SOHIT KAROL, Spotify Originally published in English: "Beyond User Needs: A Meaning-Oriented Approach to Recommender Systems" 导语:Spotify是一个在全球范围内坐拥数亿用户的音乐流媒体app,擅长以智能推荐打造高质量的听众体验。通常来说,构建智能推荐系统要从用户需求和用户目标入手。本文则试图描述一种以内容理解为导向的新思路:探究听众如何理解音乐,并根据这种理解生成智能推荐,从而让音乐体验更加深刻,让听众对音乐产生新的理解。 依托于卢锡安•卡匹克 (Lucien Karpik)于2010年提出的经济社会学理论,本文试图探索各类听众如何感受音乐、理解音乐。研究表明,听众被音乐打动有两种模式:其一是音乐层面的触动,其音乐体验的核心是音乐本身;其二是非音乐层面的触动,其音乐体验的核心是听众本人。在这两种模式当中,听众借助音乐的各种属性(内部线索)和第三方评价(外部依据)来理解音乐。听众的音乐体验可以根据他们所用到的内部线索与外部依据分为九大类型。 本文所提出的方法不仅适用于音乐平台,也可用于其他提供内容体验的数字平台和推荐系统。 关键字:内容理解,推荐系统,音乐,流媒体 在讨论数字平台、推荐系统以及注意力经济时,规模化是研究与设计当中的重要命题。对于Spotify、Netflix和Youtube这样的流媒体平台来说,商业模式注定它们要吸引大量用户;而对于用户来说,平台的价值在于提供量身定造、引人入胜的内容体验。为此,这一类用户界面要收集海量数据来生成个性化推荐,根据用户的音乐品味、所在场景、甚至是当下心情来推荐内容。 为了让每一位听众在每一次使用Spotify时都有高质量的音乐体验,Spotify面临独特的机遇和挑战。与绝大多数app不同,Spotify主要通过听觉而非视觉来缔造用户的内容体验,因此在分析改进内容体验时会有几大难点: 首先,以视觉为基础的内容类app可以根据屏幕使用时间、点赞和保存等交互行为来理解用户如何使用app。但对于Spotify来说,在按下播放键、音乐响起之后,听众就很少再与app界面产生交互,其音乐体验如何就不得而知了。此外,Spotify听众与app界面的交互在很大程度上取决于听音乐的场景:如果听众正在一边听音乐一边开车或是跑步,就基本不会与app界面有交互。 其次,如果根据音乐态度进行用户细分,各类型听众的音乐知识水平有差异,他们辨识音乐、搜索音乐、发现音乐的能力也因人而异。如何阐释音乐,音乐应该怎么听,好音乐的标准是什么……...

Human Action and the Dynamic Environment

Human Action and the Dynamic Environment
ELIZABETH CHURCHILL, Chair Google CHRIS CSIKSZENTMIHALYI Cornell University GAVIN MCCORMICK WattTime PAMELA MCELWEEN Rutgers University LIANNE YU Studio Resilience An EPIC2020 Sponsored Panel presented by Google What does human scale mean through the lens of the environment? Alternatively, what does the scale of the Earth’s environment mean to human activity and life? We may start by thinking of the enormity of the problem to just describe these two perspectives. But, by stepping back and reframing our questions in terms of the tools we use—design, ethnography, AI, art—we gain a powerful and novel perspective. Panelists discuss their work in terms of the world’s biggest threat, climate change. Approaching this topic from each one’s unique worldview and the tools of their practice, they follow out the scales of local to global and how small and seemingly one-off events can grow to a world scale. How do we design, provoke, educate—and ultimately change the world—by employing disparate data...

Tutorial: Introduction to Survey Design

JENNIFER HUNSECKER Nielsen LAUREN WALTON Nielsen Overview Ethnographers tend to be uneasy about survey research. Some of us shun it because it seems “reductive” of human experience; others are intimidated by complex methods and analytics that weren’t part of our research training. But surveys are everywhere—some are rigorous and insightful, many are lousy. Whether we’re conducting surveys, collaborating with colleagues who do, or interpreting survey-based studies, an understanding of survey research fundamentals is essential. Tutorial offers survey basics from an ethnographer and survey methodologist who collaborate at the world’s leading provider of media and marketing information. Their crash course on survey fundamentals includes: when to use surveys and why basics of survey design writing effective survey questions evaluating survey quality the total survey error framework how ethnographers and survey researchers can add value to each others’ work This tutorial is designed for...

Tutorial: Beyond “Quant-vs-Qual”—Creating Collaborative Inquiry

ALEX HUGHES UC Berkeley JENNY LO Grammarly WILL MONGE Good Research Overview Qual and quant are so divided these days—by academic discipline, language, communities of practice, job titles. Too often, quantitative research is conflated with data science (or vice versa), and data science with optimization algorithms or simply engineering. In many organizations, being “data-driven” tends to define “data” with a narrow conception of enumeration and (mis-) conceptions about the kind of evidence that is suitable to act on. This tutorial critically examines this territory and move beyond it, empowering ethnographers to develop more interdisciplinary programs of inquiry. First the instructors review fundamentals of quantitative research and provide tools ethnographers can use to evaluate its quality and validity. Then they examine constraints and barriers to quant/qual collaboration, including time, funding, values, epistemological conflicts, organizational silos, and more. Finally, using core principles that underlie...

Tutorial: Integrating Sustainability Perspectives in Ethnographic Work

MIKE YOUNGBLOOD Youngblood Group Overview This tutorial examines ways ethnography is uniquely positioned to contribute to the design and innovation of environmentally sustainable (or even better than merely sustainable) products and services. It reviews several emerging design perspectives—such as circular design, regenerative design, systems-oriented design, and value-centered design—and explores ways that ethnographers in industry can use them their own practice and organizations to build sustainability considerations into their work. It is valuable for those who are relatively new to sustainability as well as those with deeper experience who are interested in expanding our collective impact toward more planet-friendly industries. The session covers: Opportunity costs of doing design research “as usual” Key perspectives and approaches for sustainable design and innovation Baking sustainability perspectives into research Ethnographic/anthropological theories and methods that can support a sustainability...

Keynote Address: Bruce Pascoe

BRUCE PASCOE In this keynote address, we join indigenous writer, historian and agriculturalist Bruce Pascoe on his farm on the South East coast of Australia. Bruce employs the theme of Caring to speak to a range of topics close to his heart. While walking on Country with him, we are taken to a ceremonial site on his land that illustrates the importance of cultural heritage, reconciliation, and language to contemporary farming practices in Australia. We visit a forest landscape devastated by the ‘superfires’ experienced over Australia’s 2019/2020 summer, where we learn of the importance of indigenous approaches to land management and controlled burning. Introducing us to some of the nutritious plants and vegetables that indigenous people cultivated in pre-colonial Australia, Bruce talks us through his farming team’s current experiments and future plans to develop indigenous agriculture on a commercial scale on the farm, and he foregrounds the importance of training a new generation of indigenous farmers, chefs, botanists,...

Going to Scale: Lessons from the Pandemic

GENEVIEVE BELL Australia National University The pandemic has disrupted everything from the global flow of goods and services, to the actions that individuals can take in their daily lives. It has changed, for now at least, the ecosystems in which we work—impacting both how we think about ethnographic activity and how it is might be used. In Australia, the pandemic has resulted in a collection of massive, unplanned, social experiments in scale, at scale. Examining five of these social experiments as they’ve played out, Genevieve will extract lessons that seem relevant to the work we all do now and to the ways we might want to orient to the future. After all, as the pandemic is demonstrating, scale is neither a stable nor singular concept, and our responses to it will need to be appropriately located and considered. Genevieve Bell is a Distinguished Professor, Director of the 3A Institute (3Ai) and Florence Violet McKenzie Chair at the Australian National University. She is also Vice President and a Senior Fellow at Intel...

Post-Human Centered

ALICIA DUDEK, Chair Mycoreality IAN BOGOS Georgia Institute of Technology SUSAN MOYLAN COOMBS Gaimaragal Group TRICIA WANG Sudden Compass We invented our world at human height, with us in the middle. Much of our work is designed even more narrowly, with a particular kind of human at the middle. What happens when we go beyond the limited “user-centric” or “human-centric” scales? What does it look like, feel like, move like when humans are not in the middle of the system? Panelists Alicia Dudek is an experienced design ethnographer and futurist. Her work brings the customer’s point of view and human voice to any group’s innovations and decisions. The work she does with teams brings empathy into the organisation to help inform, inspire, and initiate innovation.
