Towards Conceptual Foundations of Requirements Engineering for Services
A service-oriented system should be engineered to satisfy the requirements of its stakeholders. Requirements are understood in terms of stakeholder goals, softgoals, quality constraints, preferences, tasks, and domain assumptions. The service-oriented system is viewed in terms of services, mediators, choreographies, and orchestrations, among others. To engineer the system according to requirements, it is necessary to…

Machine/AI as Inventor? Notes on Thaler v. USPTO
Can “an artificial intelligence machine be an ‘inventor’ under the Patent Act”? According to the Memorandum Opinion filed on September 2, 2021, in the case 1:20-cv-00903, the US Patent and Trademark Office (USPTO) requires that the inventor is one or more people [1]. An “AI machine” cannot be named an inventor on a patent that…
Engineering Pluripotent Information Systems
A pluripotent information system is an open and distributed information system that (i) automatically adapts at runtime to changing operating conditions, and (ii) satisfies both the requirements anticipated at development time, and those unanticipated before but relevant at runtime. Engineering pluripotency into an information system therefore responds to two recurring critical issues: (i) the need…
Achieving, Satisficing, and Excelling
Definitions of the concepts derived from the goal concept (including functional and nonfunctional goal, hardgoal, and softgoal) used in requirements engineering are discussed, and precise (and, when appropriate, mathematical) definitions are suggested. The concept of satisficing, associated to softgoals is revisited. A softgoal is satisficed when thresholds of some precise criteria are reached. Satisficing does…
