Methods, systems, and devices for lexical classification, grouping, and analysis of documents and/or document corpora

A computationally-implemented system, comprising means for selecting a target portion of a source document;

• means for presenting a representation of the target portion of the source document to a client;
• means for accepting input from the client that is configured to separate the target portion of the source document into a set of one or more designated lexical units;
• means for receiving association input from the client, said association input configured to associate at least one designated lexical unit with a further portion of the source document that is different than the target portion;
• and
• means for providing an output structure that represents the set of one or more designated lexical units.
