VisualText 1.2, by Text Analysis International, Inc.

VisualText is the first integrated development environment (IDE) for natural language processing (NLP). It is the most advanced commercial tool available for constructing not only information extraction and tex analysis systems, but the whole gamut of NLP applications, such as machine translation, language generation, ontology building,
categorization, summarization, grammar critiquing, and more.

VisualText builds multi-pass, multi-strategy analyzers that communicate via a single parse tree per text and also via a shared hierarchical KBMS (Knowledge Base Management System) called Conceptual Grammar.
Constraining the analysis to produce a single parse tree practically forces an efficient and fast analyzer to be built. Ambiguity information and competing hypotheses can be carried in the parse tree nodes.

A key aspect of VisualText is a rich, highly integrated user interface that ties together text views, parse tree views, knowledge base views, highlighting of text corresponding to the work done by each pass, instant navigation from syntax errors and parse tree nodes to their corresponding rule and line of code, and much more.

VisualText incorporates the simple yet powerful NLP++ programming language, which combines rewrite rules, a C/C++ style programming language, and data types for parse tree nodes, parse tree semantics, as well as knowledge base concepts, attributes, and values.

The VisualText development environment interprets NLP++, supporting a rapid modify-and-test development cycle. An automated rule generation capability applies to user-highlighted (or ''annotated'') text samples, supporting the construction of analyzers that can be maintained by non-expert users.

The development environment is supported on Windows NT, 2000, 98, and ME. The runtime libraries for analyzers developed (and optionally compiled) with VisualText run on Windows, Linux, and effectively on any platform with a Gnu C++ compiler or equivalent.
VisualText is an open architecture, allowing user or 3rd party code to be integrated with an analyzer, as well as supporting user extensions to the NLP++ language itself.

To enable faster implementation of analyzers, TAI can make available prior to release two general analyzers, TAIParse and GenTxt. Sample applications include an advanced analyzer for web resumes.

VisualText can serve not only as a development environment, but as a workbench for analysts, for annotation, and quality review. It is an ideal substitute for languages such as Perl in many document processing, format conversion, and pattern matching tasks.

Documentation is extensive and well-integrated with the developmen environment.
