Sorry, I did not read the text carefully enough and interpret in a way that the TM is already existing. TM generation from any kind of resource is really a challenge. It is even more challenging than getting word processing formats into nicely structured XML. Why? Because generating TMs is about detecting "knowledge" in data/information. Two approaches are promissing and could be somehow generalized: - Use linguistics software on text documents and live with the uncertainties and quality lacks this approach has. - Map XML (SGML) structures to TM constructs (could be used in conjunction with the linguistics stuff to find e.g. assocs). - Use intelligent mapping between relational data in RDBs and TM constructs. Everything else will be hard to generalize because it highly depends on the quality of the input data. I liked the idea Kal and SteveP presented in Austin in their Tutorial. Kal described a way to use a fixed in between DTD which is the target format of a first "conversion" step. For this DTD he provided a tool set to do the flexibble mapping into a TM. It is similar to the Rainbow idea EBT offered a couple of years ago to convert from various text formats into SGML. --Holger -- Dr. H.
