Semantic document routing (SDR) is the practice of automatically reading an incoming document, working out what it is about, and then sending it on to the team or workflow that should handle it, using the meaning of the text rather than a fixed list of keyword rules.

What semantic document routing is

SDR turns raw uploads (invoices, claims, IDs, contracts, etc.) into a labelled queue entry, so every item lands in the right pipeline, approval chain, or archive. It shows up most often across banking, insurance, healthcare, logistics, and legal teams that want to cut the hours lost to manual triage each week.

In upload-based SDR, two core sub-steps are:

• Intent Span Tagging (IST): marks the spans that carry the routing signal (party, matter type, due date).
