Information Integration Overview

The Information Integration (I2) Group focuses on developing systems that stitch together heterogeneous data and information originating in multiple formats and from multiple sources – whether structured (e.g., databases), semi-structured (e.g., Web pages), or unstructured (e.g., documents). The goal of I2 systems is to bring together all information relevant to customers into a common framework that enables cross-source functionality, such as consolidated search, centralized data access, and comprehensive data analysis. To accomplish this type of data integration, we use a variety of techniques ranging from data warehousing, data federation, and data virtualization, to semantic integration, knowledge graphs, and linked data representations. Data systems have been developed within I2 to integrate many different types of NASA-relevant data, ranging from air traffic management data, to International Space Station data, to biological sciences data.
