Abstract: A computer-implemented method identifies textual statement relationships. Textual statement pairs including a first and second textual statement are identified, and parsed word group pairs are extracted from first and second textual statements. The parsed word groups are compared, and a parsed word score for each statement pair is calculated. Word vectors for the first and second textual statements are created and compared. A word vector score is calculated based on the comparison of the word vectors for the first and second textual statements. A match score is determined for the textual statement pair, with the match score being representative of at least one of the parsed word score and the word vector score.

Abstract: A requirement statement manipulation system is configured to create and edit requirement statements of various types. The requirement statement manipulation system may generate an interactive visual environment to receive input used in manipulating a requirement statement through creation or editing. The interactive visual environment may include specific requirement-type interfaces allowing requirement statements of a specific type to be manipulated. The interactive visual environment may manipulate requirement statements based on textual input, as well as through text generation.
