Trends and Challenges in Requirement Analysis for; Modern Web Applications, Web Services, and Web of Things

Requirements are the key to develop any software. Requirement engineering is a specific discipline of software engineering where one can gather, analyze and evaluate the requirements of particular software. Requirement analysis is the phase of requirement engineering, which refines the requirements according to the technicality of the software. When it comes to web engineering, the importance of requirement engineering specifically requirement analysis becomes more important because of the complexity of the web-based software projects. This paper identifies some invisible trends and challenges in the requirement analysis phase while developing any sort of web related products, services or web of things. Through a systematic literature review, it is well known fact that web applications and web services are fully handled with RE but WoT struggling in the field of requirement engineering. These challenges are then validated from different software houses. Researchers are trying to solve the associated challenges with WoT. 12 challenges and 25 new trends are identified for the requirement analysis in web engineering
