[Synthesis Extraction] Step extraction inconsistencies #18
Description
The synthesis steps generation from the extraction pipeline introduces some inconsistencies:
- Not all properties are generated for all step types (e.g., 'Filter' steps currently do not have a duration while 'Add' steps do)
- Default values that are created when no information is available are different (while most literals are set to "N/A", numbers are sometimes 0 or -1 etc.; this is not just an issue for identifying all unknown values in one go but can create confusion, for example standard pH is -1 which is a valid value)
