Aspects of the disclosed technology present a workspace window responsive to a relationship data structure that represents a comprehension state including a presentation set of an ordered set of text strings from an electronic document. The presentation set includes one or more identified strings. The workspace window can then receive a quick-click command invocation on the one or more identified strings and modifies the relationship data structure by adding an entity/relationship object to the relationship data structure responsive to the quick-click command invocation and the one or more identified strings. The application relates to sensemaking or maintaining a comprehension state of a document collection, by recording evidence, spatial hypertext, automatic highlighting, automating inferencing, reading recommendations, and reading through multiple documents.
