Analysing Quality of Textual Requirements Using Natural Language Processing: A Literature Review

摘要

Requirements engineering plays an important role in quality assurance, which is especially important for complex, embedded, safety-related systems. Such systems are often subject to additional regulations regarding functional safety such as ISO 26262 norm for road vehicles or EN 50128 for railway industry. Verifying quality of the requirements is a first step both for validation and verification of the system under test. This paper presents a review of the existing methods of automatic detection of the ambiguity and automatic assessment of the requirements quality together with the possible, future fields of research.
