Abstract

Context. A large amount of data is made available daily on the Web, but many databases cannot be accessed by conventional search engines, as they require proper access methods and specialised knowledge through their access languages. Focus. In the scenario of non-expert users to access databases, multiple database categories, and plural idioms, this work analyzes the functional requirements that need to be considered for keyword queries processing over data sources on the Web. The problem is still open and involves challenges such as query interpretation and access to databases. Method. The investigation is centered on the problem itself, which is portrayed by a set of functional issues, which together represent the challenges linked to the research field. Approach. This work introduces and systematically analyzes the functional requirements to the problem scope. Issues reported in the literature are refined and evolved to support the modeling of the problem views: functional responsibilities and their interactions by messaging between problem objects. Conclusions and Results. This paper contributes to characterize the problem, makes clearer its understanding and promotes the development of keyword-based query processing systems. A software engineering artifact is used to model the problem and make it more formal and precise. Further studies will refine such requirements and build (specialise) artifacts tailored to the solution space.
