Uniform Resource Identifier (URI) may be viewed as a sequence of characters chosen from a subgroup of ASCII characters that identifies an abstract or physical resource [28,29]. These characters are representative of words in natural languages. URI is decked by three entities—uniformity, resource, and identifier—with each contributing a unique adornment to the entire concept of URI. It is evident from [28] that while uniformity enforces consistency, resource depicts anything abstract or physical that is identifiable by URI, and identifier holds vital information to differentiate an identified resource from every other within its scope of identification. The adoption of this simple and extensible mechanism presents huge benefits which includes allowing (i) usage of different types of resource identifiers in the same contexts even with differences in access mechanism deployed, (ii) reusability of identifiers in diverse contexts, (iii) existence of a consistent semantic interpretation of common syntactic protocols across disparate types of resource identifiers, and (iv) introduction of new types of resource identifier without interfering with the way that existing identifiers are used [28,29]. Figure 1.3 is a representation of a typical URI and its components.

An identifier is a name given to an object or variable so that it can be referenced elsewhere in the design. Identifier names are used for modules, registers, ports, wires, or module instance names. Also, begin . . . end blocks may include an identifier. An identifier consists of a sequence of characters that can be letters, digits, $, or underscore ( _ ). The first character of an identifier must be a letter or an underscore. The $ character is reserved for system tasks. Identifiers are case sensitive. For example, Clock and clock are different identifiers. An identifier refers to a unique object in the module in which it is defined.

Identifiers play a vital role in source code maintainability, readability, and comprehensibility [38, 39]. Generally, identifiers refer to the names of any source code entities, e.g. classes, variables, attributes, and methods [40]. According to Deißenböck and Pizka [41], identifiers account for approximately of source code in terms of characters. Consequently, the names chosen as identifiers should better reveal the functionality of the related entities and improve program comprehension [41]. However, for particular reasons such as software evolution, tight development schedule and lack of developer's experience, poorly named identifiers can be introduced into the source code. To get rid of this problem, extensive research have been devoted in identifying rename refactoring opportunities.
