Abstract: Systems and methods for change in language-based textual analysis are disclosed. In one embodiment, in an information processing apparatus comprising at least one computer processor, a method for change in language-based textual analysis may include: (1) retrieving, from a data source, a first document of a first type; (2) retrieving, from the data source, a second document of the first type, the second document being subsequent in time to the first document; (3) identifying changes between the first document and the second document; (4) calculating a change score based on the changes; and (5) providing the change score to a downstream system for projecting a performance of an investment associated with the first document.
