Technical Specifications

Mentext components
Mentext includes the following elements:

Engine DLLs *	The program code for the Mentext AI components
Language files *	Files containing language-specific data used by the AI components
Documentation	Help files detailing how to use Mentext
Sample application and source code	Application in C++ demonstrating Mentext in use
Type libraries and header files	Allow use of Mentext components in C++, VB, ASP and scripting environments
Licence control applet	Enables installation of updates, upgrading and viewing licences

* These files are redistributable in your finished application if you have purchased the correct edition

System requirements
Requirements are the same for both the developer and the end-user running the application which the developer has written:

• Windows XP, 2000, ME, 98, NT4 or 95 (server systems require Mentext Server Edition)
• 450 MHz processor
• 64 MB memory
• 10 MB disk space
• 800x600 display resolution with 256 colours minimum (1024x768 with 16bit colour recommended)

Development with Mentext
Developers will need a development environment compatible with COM/ActiveX components, and will need to be familiar with programming using component objects.

Mentext is compatible with projects written in most languages including C++ and Visual Basic, ASP or object based macro/scripting languages such as VBA.

Mentext processing model
Mentext is based on a 2-stage processing scheme:

• Extraction stage - text is processed by Mentext to yield an opaque meaning object representing the meaning of the text
• Comparison stage - meaning objects are compared by Mentext to determine whether the underlying text has equivalent meaning

Because the extraction stage is much slower than the comparison stage, it is usual to perform the extraction stage on fixed 'target' text once and cache the results for later comparison.

The use of an opaque meaning representation object shields the developer from the complexities of the AI's internal processing and allows for rapid implementation of the technology in a range of application scenarios.

Diagnostic information
Mentext contains additional features which run on the developer's computer to help with diagnosing problems and to indicate processing progress. These features are disabled in any redistributed versions of Mentext incorporated into the developer's application.
