A lot of these can be handled by simple mappings; I suggest at ingestion (plus a one-time change):

- \textgreater, \textless, \dots, \textemdash

Some can be handled with HTML conversions:

- \mathbf (add to existing list with \bf and \textbf)
- \mathcal

Some are garbage and should just be fixed manually
- \DALI

Start in texmath.py around line 171 and trace how LaTeX is handled during ingestion. Review the suggested mappings and HTML conversions, then run ingestion against abstracts containing the listed commands; done means the supported commands no longer produce unknown-command warnings, while \DALI is handled manually as noted.
