Linked Visual Analysis of Structured Datasets and Document Collections

摘要

Analysts use visual analytical systems for exploring and analyzing structured datasets and increasingly require tools to access supporting documents, research papers and news reports. Visual analytical systems for text corpora typically concentrate on techniques for exploring only document collections. We have developed a system for visualizing and analyzing both document collections and structured datasets. We describe a document visualization tool called InfoMaps developed by us within Weave, an open source framework for data exploration and analysis. Users of Weave analyzing datasets can search for documents from the web and networked repositories, and can use the matched documents as a part of their analysis. Conversely documents in InfoMaps can be used to identify relevant data subsets. In this paper, we discuss InfoMaps, its use and integration with other visual tools of Weave and our approach to the information extraction and integration process.
