Collaborative Research: BlogoCenter - Infrastructure for Collecting, Mining and Accessing Blogs

BlogoCenter项目是一项合作努力（0534784，Junghoo 'John' Cho，加州大学洛杉矶分校和0534323，Dragomir Radev，密歇根大学安阿伯），目标是开发用于构建系统的创新技术，该系统（1）连续监视、收集和存储个人博客（2）自动从博客中发现隐藏的结构和趋势;以及（3）使它们易于被普通用户访问。通过使博客上的新信息易于发现和访问，该项目正在帮助博客实现其作为“基层媒体”的社会变革的全部潜力。它还收集了一个重要的人类互动超文本数据集，供社会和行为科学研究团体进一步分析。在开发这样一个系统的过程中，该项目研究了三个领域的新的研究挑战：（1）新的监测算法，以最小的延迟从快速变化的分布式源中发现和下载新的信息;（2）适合于大规模超文本语料库的新的文本和图形挖掘技术;以及（3）新颖的文本排序和摘要算法，以帮助用户从快速发展的博客中快速获取新的和高质量的信息。该项目将通过网络（http：//www.eecs.umich.edu/blogocenter）向其他研究小组提供所收集的数据集和原型源代码，加速与博客有关的研究的进展，从而对科学界产生重大影响。新的研究成果将通过科学会议和期刊传播，促进分布式Web源监控，文本摘要和排名以及大规模文本和图形挖掘的重大进展。此外，该项目将支持研究生和本科生的研究，并促进跨机构的合作。

The BlogoCenter project is a collaborative effort (0534784, Junghoo 'John' Cho, University of California-Los Angeles and 0534323, Dragomir Radev, University of Michigan Ann Arbor) with a goal to develop innovative technologies for building a system that (1) continuously monitors, collects, and stores personal Weblogs (or blogs) at a central location; (2) discovers hidden structures and trends automatically from the blogs; and (3) makes them easily accessible to general users. By making the new information on the blogs easy to discover and access, this project is helping blogs realize their full potential for societal change as the "grassroots media." It is also collecting an important hypertext dataset of human interactions for further analysis by the social and behavioral sciences research communities. In developing such a system, the project investigates new research challenges in three areas: (1) novel monitoring algorithms that discover and download new information from rapidly-changing distributed sources with minimal delay; (2) new text and graph mining techniques appropriate for large-scale hypertext corpora; and (3) novel text ranking and summarization algorithms to help the users access new and high-quality information quickly from the rapidly-evolving blogs. The project will make a significant impact to the scientific community by making the collected datasets and the source code of the prototype available to other research groups via the Web (http://www.eecs.umich.edu/~radev/blogocenter), accelerating progress in the blog-related research. The new research findings will be disseminated via scientific conferences and journals, spurring significant advancements in distributed Web-source monitoring, text summarization and ranking, and large-scale text and graph mining. In addition, this project will support graduate and undergraduate student research and foster cross-institution collaboration.
