Every day, millions of people across the world take photos and upload them to social media websites. Their goal is to share photos with friends and others, but collectively they are creating vast repositories of visual information about the world. Each photo is an observation of how the world looked at a particular point in time and space. Aggregated together, these photos could provide new sources of observational data for use in disciplines like biology, earth science, social science or history. This project is investigating the algorithms and technologies needed for mining these large collections of photographs and noisy metadata to draw inferences about the physical world. The project has four research thrusts: (1) investigating techniques for identifying and correcting noise in metadata like geo-tags and timestamps, (2) developing algorithms for extracting semantic information from images and metadata, (3) creating methods for robust aggregation of noisy evidence from multiple photos, (4) validating these techniques on interdisciplinary applications in biology, sociology, and earth science.The project is laying the foundation for using visual social media as a new source of observational data for a variety of scientific disciplines. The educational component is preparing students for the next generation of "big data" jobs through new undergraduate and graduate courses and online instructional materials. Undergraduate students (particularly from under-represented groups) are recruited to participate in the research program and encouraged to pursue scientific careers. An annual workshop is planned to educate general audiences, particularly senior citizens, about data mining and social media. Source code, datasets, course materials, and other results of the project will be disseminated to the public via the project web site (http://vision.soic.indiana.edu/career/).

每天，全世界数以百万计的人拍照并上传到社交媒体网站。他们的目标是与朋友和其他人分享照片，但总的来说，他们正在创建关于世界的巨大视觉信息存储库。每一张照片都是对世界在特定时间点和空间点的观察。综合起来，这些照片可以提供新的观测数据来源，用于生物学、地球科学、社会科学或历史等学科。这个项目正在研究挖掘这些大量照片和嘈杂元数据以得出关于物理世界的推论所需的算法和技术。该项目有四个研究重点：(1)研究识别和纠正地理标签和时间戳等元数据中的噪声的技术；(2)开发从图像和元数据中提取语义信息的算法；(3)创建从多张照片中稳健聚集噪声证据的方法；(4)验证这些技术在生物学、社会学和地球科学中的跨学科应用。该项目正在为将可视化社交媒体用作各种科学学科的观测数据的新来源奠定基础。教育部分正在通过新的本科生和研究生课程以及在线教学材料，让学生为下一代“大数据”工作做好准备。本科生(特别是来自代表人数不足的群体)被招募参加研究计划，并鼓励他们从事科学事业。计划举办一次年度研讨会，教育普通受众，特别是老年人，了解数据挖掘和社交媒体。项目的源代码、数据集、课程材料和其他成果将通过项目网站(http://vision.soic.indiana.edu/career/).)向公众传播
