the only problem is that it is based on ie….

MnM is an annotation tool which provides both automated and semi-automated
support for annotating web pages with semantic contents. MnM integrates a web
browser with an ontology editor and provides open APIs to link MnM to ontology
servers and for integrating MnM with information extraction tools. MnM works with a number of representation languages, including RDF, DAML+OIL and OCML. The annotated documents can be used to populate ontologies or as a training corpus for information extraction (IE) engines. The MnM IE plug-in is generic and documented and therefore developers can add new IE mechanisms to the system.

The version of MnM available for download has been integrated with Amilcare Version 2.1, a tool for Adaptive Information Extraction from Texts. Amilcare has been developed by Fabio Ciravegna, University of Sheffield, F.Ciravegna@dcs.shef.ac.uk, http://www.dcs.shef.ac.uk/~fabio. This version of Amilcare has been released as demo as part of the MnM tool and CAN BE USED ONLY AS PLUG-IN FOR THE MnM tool. It cannot be used in stand alone or as plugin for any other annotation tool.
Please contact Fabio Ciravegna if you want to use Amilcare in commercial applications, distribute it to other colleagues or integrate it in other tools.

MnM is provided “as is” and it is free of charge for non commercial
use (see http://kmi.open.ac.uk/projects/akt/MnM/license.html for more details).

For more information about MnM you can have a look at the published papers

manual and developer guide (http://kmi.open.ac.uk/projects/akt/MnM/documents.html).
