Abstract

U-report is an open-source SMS platform operated by UNICEF Uganda, designed to give community members a voice on issues that impact them. Data received by the system are either SMS responses to a poll conducted by UNICEF, or unsolicited reports of a problem occurring within the community. There are currently 200,000 U-report participants, and they send up to 10,000 unsolicited text messages a week. The objective of the program in Uganda is to understand the data in real-time, and have issues addressed by the appropriate department in UNICEF in a timely manner. Given the high volume and velocity of the data streams, manual inspection of all messages is no longer sustainable. This paper describes an automated message-understanding and routing system deployed by IBM at UNICEF. We employ recent advances in data mining to get the most out of labeled training data, while incorporating domain knowledge from experts. We discuss the trade-offs, design choices and challenges in applying such techniques in a real-world deployment.

通过文本分析放大非洲青年的声音

U-report是联合国儿童基金会乌干达办事处运营的一个开源短信平台，旨在让社区成员就影响他们的问题发表意见。该系统收到的数据要么是对联合国儿童基金会进行的民意调查的短信答复，要么是关于社区内发生的问题的主动报告。目前有20万u -报告参与者，他们每周发送多达1万条主动短信。乌干达项目的目标是实时了解数据，并由联合国儿童基金会的相关部门及时解决问题。考虑到数据流的高容量和速度，对所有消息进行人工检查不再是可持续的。本文描述了IBM在联合国儿童基金会部署的自动消息理解和路由系统。我们采用数据挖掘的最新进展来最大限度地利用标记的训练数据，同时结合专家的领域知识。我们将讨论在实际部署中应用这些技术的权衡、设计选择和挑战。
