Brief Introduction
Each stage of development process can be treated as a series of “translations” from one language to another. At the very beginning a project team deals with customer’s requirements and expectations expressed in natural language. These customer requirements sometimes might be incomplete, vague or even contradictory to each other. The first step is specification and formalization of customer expectations, transition (“translation”) of them into a formal requirement document for the future system. Then requirements are translated into system architecture and step by step the project team generates megabytes of code written in a very formal programming language. There is always a threat of inserting mistakes, misinterpreting or losing something during the translation. Even a small defect in requirement or design specifications can cause huge amounts of defects at the late stages of the project. Sometimes such misunderstandings can lead to project failure or complete customer dissatisfaction.
The highest usage scenarios of Reverse Semantic Traceability method can be:
- Validating UML models: quality engineers restore a textual description of a domain, original and restored descriptions are compared.
- Validating model changes for a new requirement: given an original and changed versions of a model, quality engineers restore the textual description of the requirement, original and restored descriptions are compared.
- Validating a bug fix: given an original and modified Source code, quality engineers restore a textual description of the bug that was fixed, original and restored descriptions are compared.
- Integrating new software engineer into a team: a new team member gets an assignment to do Reverse Semantic Traceability for the key artifacts from the current projects.

Famous quotes containing the word introduction:
“We used chamber-pots a good deal.... My mother ... loved to repeat: “When did the queen reign over China?” This whimsical and harmless scatological pun was my first introduction to the wonderful world of verbal transformations, and also a first perception that a joke need not be funny to give pleasure.”
—Angela Carter (1940–1992)
“For the introduction of a new kind of music must be shunned as imperiling the whole state; since styles of music are never disturbed without affecting the most important political institutions.”
—Plato (c. 427–347 B.C.)
