Generate table descriptions
To generate table descriptions, in an Enrichment node in a workflow, select Table, and then choose one of the available provider (and model) combinations that are shown. Make sure after you choose the provider and model, that Table Description is also displayed. If Table Description and Table to HTML are both displayed, be sure to select Table Description.You can change a workflow’s table description settings only through Custom workflow settings.For workflows that use chunking, the Chunker node should be placed after all Enrichment nodes. Placing the
Chunker node before a table descriptions Enrichment node could cause incomplete or no table descriptions to be generated.
Unstructured can potentially generate table summary descriptions only for workflows that are configured as follows:
- With a Partitioner node set to use the Auto or High Res partitioning strategy, and a table summary description node is added.
- With a Partitioner node set to use the VLM partitioning strategy. No table summary description node is needed (or allowed).
- High Res, when the workflow’s Partitioner node is set to use Auto or High Res.
- VLM or High Res, when the workflow’s Partitioner node is set to use VLM.
- With a Partitioner node set to use the Fast partitioning strategy.
- With a Partitioner node set to use the Auto, High Res, or VLM partitioning strategy, for all files that Unstructured encounters that do not contain tables.
