In one embodiment, a method is provided for deriving use case diagrams for software development. The method comprises extracting one or more core components from each of a plurality of software development requirements, determining at least one activity from the one or more core components, extracting at least one of a class and an attribute from the one or more core components, and deriving at least one use case diagram based on the at least one activity and the at least one of the class and the attribute. The one or more core components comprise at least one of a core message and a condition. ## Claims ### Claim 1 A method for deriving use case diagrams for software development, the method comprising: retrieving, by a modeling engine, one or more core components from each of a plurality of software development requirements, wherein the one or more core components comprise at least one of a core message and a condition, and wherein the plurality of software development requirements are in unstructured textual format; determining, by the modeling engine, at least one activity from the one or more core components; determining, by the modeling engine, at least one of a class and an attribute from the one or more core components, wherein determining the class comprises determining the class from the core message based on a pre-defined set of rules and a statistical model via an iterative shortlisting process; and deriving, by the modeling engine, at least one use case diagram based on the at least one activity and the at least one of the class and the attribute, wherein deriving the at least one use case diagram comprises aggregating a set of similar activities from the at least one activity based on domain knowledge. ### Claim 2 (depends on 1) The method of claim 1, wherein retrieving one or more core components comprises: determining a plurality of tokens from each of the plurality of software development requirements, wherein each of the plurality of tokens comprises a word or a phrase; determining a plurality of part of speech (PoS) tags corresponding to the plurality of tokens; and determining a plurality of PoS patterns based the plurality of PoS tags. ### Claim 3 (depends on 2) The method of claim 2, wherein determining the at least one activity comprises determining the at least one activity from the at least one of the core message and the condition by: aggregating the plurality of PoS patterns to determine a language pattern; parsing the language pattern to determine the at least one activity and a relationship. ### Claim 4 (depends on 3) The method of claim 3, further comprising deriving at least one activity diagram based on the at least one activity and the relationship. ### Claim 5 (depends on 2) The method of claim 2, wherein determining the attribute comprises determining the attribute from the core message by matching the plurality of PoS patterns against a plurality of pre-defined attributes. ### Claim 6 (depends on 1) The method of claim 1, further comprising deriving at least one class diagram based on the at least one of the class and the attribute. ### Claim 7 (depends on 1) The method of claim 1, wherein deriving the at least one use case diagram further comprises: rendering the set of similar activities as the at least one use case diagram. ### Claim 8 (depends on 7) The method of claim 7, wherein the domain knowledge comprises a plurality of historical activities with a corresponding similarity index. ### Claim 9 (depends on 1) The method of claim 1, further comprising: validating the at least one use case diagram based on a pre-defined set of rules to determine one or more deviations from best practices; and generating one or more recommendations based on the one or more deviations. ### Claim 10 A system for deriving use case diagrams for software development, the system comprising: at least one processor; and a computer-readable medium storing instructions that, when executed by the at least one processor, cause the at least one processor to perform operations comprising: retrieving one or more core components from each of a plurality of software development requirements, wherein the one or more core components comprise at least one of a core message and a condition, and wherein the plurality of software development requirements are in unstructured textual format; determining at least one activity from the one or more core components; determining at least one of a class and an attribute from the one or more core components, wherein determining the class comprises determining the class from the core message based on a pre-defined set of rules and a statistical model via an iterative shortlisting process; and deriving at least one use case diagram based on the at least one activity and the at least one of the class and the attribute, wherein deriving the at least one use case diagram comprises aggregating a set of similar activities from the at least one activity based on domain knowledge. ### Claim 11 (depends on 10) The system of claim 10, wherein retrieving one or more core components comprises: retrieving a plurality of tokens from each of the plurality of software development requirements, wherein each of the plurality of tokens comprises a word or a phrase; determining a plurality of part of speech (PoS) tags corresponding to the plurality of tokens; and determining a plurality of PoS patterns based the plurality of PoS tags. ### Claim 12 (depends on 11) The system of claim 11, wherein determining the at least one activity comprises determining the at least one activity from the at least one of the core message and the condition by: aggregating the plurality of PoS patterns to determine a language pattern;
