Charting extraction results
After i2 TextChart has imported and processed a collection of documents and you have curated the results, you can add the extracted entities and links to an Analyst's Notebook chart. TextChart supports sending results to the chart separately or in bulk.
Sending entities to a chart
TextChart provides three options for sending entities to a chart. You can specify them individually, choose all entities of the same type, or simply send all the extracted entities at once.
Sending a single entity
To send a single entity from the Document View to a chart, you can use the pop-up menu for that entity in the Entities list on the left of the window, or the Send To Chart button from the entity details pane on the right of the window.
If an extracted entity is already on the chart, you can use the same pop-up menu to select it there.
Sending several entities
To send all the entities of the same type from the Document View to a chart, you can use the pop-up menu for that entity type in the Entities list. Alternatively, to send all the entities extracted from the document to the chart, you can click the Send All button at the top of the list.
Viewing entities on the chart surface
You can hover over any entity on the Analyst's Notebook chart surface to display a window containing information about all the attributes that are associated with that entity.
After you've added an entity from TextChart to the chart, you can use it to start adding related entities from the other documents that you've processed. Right-click the entity, and select Rosoka Expand.
You can choose to add related entities of particular types, or groups of types; or you can use Select All to add all related entities in a single action.
When a chart contains multiple TextChart entities, you can perform the same Rosoka Expand operation on all of them by right-clicking the chart surface and choosing Select All first.
Listing source documents
For any TextChart entity or link on the the Analyst's Notebook chart surface, you can quickly refer back to the documents from which it was extracted.
To retrieve all the documents for a chart entity, right-click and select Show In Documents to reopen the Document View.
On the left of the view, the list of documents that contain the entity allows you to select which document appears on the right. Each document appears with text highlighting that reveals the entity in question.
Similarly, to retrieve all the documents for a chart link, you can use the same Show In Documents command.
Extracted links are then highlighted in the documents that contain them, in the same way as for extracted entities.
