| - AeroText is a suite of text mining applications that are used for content analysis. Content used can be in multiple languages.
AeroText is a solution developed at the Integrated Systems and Solutions division of Lockheed Martin Corporation, a leading U.S. Defense contractor. Originally developed for the U.S. intelligence community(Department of Defense), the solution has become one of the leading solutions available and is often integrated into other solutions. AeroText solutions provide both information extraction and link analysis capabilities.
AeroText converts unstructured information into structured information. The user has the capability to define the parameters of both.
AeroText output is normalized and stored within the solution’s cache as templates. However, the information can be output in a variety of ways using the Run Time Integration Toolkit (RIT) to integrate the output into existing systems through the use of RIT modules. Wrappers for XML and the DARPA Agent Markup Language ( DAML) and also provided, thus making the solution flexible enough to be utilized in other domains. For instance, the solution was presented to the National Institute of
Health’s Biomedical Computing Interest Group (BCIG) in April 2002 and demonstrated excellent applicability to the biomedical domain.
“AeroText is data-independent, which means it does not rely on or have a bias towards a particular domain, document type, document source, or natural language” (Haser and Childs, 2002). Sample target applications include automatic database generation, document routing, browsing, summarization, enhanced full text search, and targeted document search in addition to link analysis. The solution’s multilingual utility is also a strength. The technology is also flexible enough to be able to support format standards, such as DAML (Kogut and Holmes), which aid in law enforcement activities.
The current 5.x release exists as a set of various components that are used to carry out integration and data mining tasks. The Integrated Development Environment (IDE) is, perhaps, the most important component as it provides the rule development, modification, and coordination capabilities – “a complete environment to build, test, and analyze linguistic knowledge bases” (Kogut and Holmes). This graphical interface includes not only object oriented editors and rules wizards, but is also allows visual tools for analyzing extracted data, debugging linguistic data, and analyzing performance (AeroText). As a result, customized logic domains are available.
The Instance Based Run-Time Engine actually carries out the extraction on input documents by applying a Knowledge Base (see below). According to the company, “an Instance is defined as the creation of a single Document Object in the AeroText Application Program Interface (API).” The engine is available in Java, C, or COM APIs and has wrappers for XML and DAML.
