A Vital Text Analytics System (VTAS), incorporating a repository of enterprise terms or concepts, is one that improves the readability and fidelity of technical specifications, instructions, training manuals requirements engineering documents and other related engineering documents, typically from a single organization or workgroup. The system stresses ontological analysis of a corpus of related documents, and applies a suite of computational tools that supports the identification and assessment of risk in evaluating the content of the documents, as well as providing statistical measures reflecting the frequency and severity of document features that threaten comprehension.
