  In requirements specification, software engineers create a textual
description of the envisioned system as well as develop conceptual models using
such tools as Universal Modeling Language (UML) and System Modeling Language
(SysML). One such tool, called FM, has recently been developed as an extension
of the INPUT-PROCESS-OUTPUT (IPO) model. IPO has been used extensively in many
interdisciplinary applications and is described as one of the most fundamental
and important of all descriptive tools. This paper is an attempt to
understanding the PROCESS in IPO. The fundamental way to describe PROCESS is in
verbs. This use of language has an important implication for systems modeling
since verbs express the vast range of actions and movements of all things. It
is clear that modeling needs to examine verbs. Accordingly, this paper involves
a study of English verbs as a bridge to learn about processes, not as
linguistic analysis but rather to reveal the semantics of processes,
particularly the five verbs that form the basis of FM states: create, process,
receive, release, and transfer. The paper focuses on verb classification, and
specifically on how to model the action of verbs diagrammatically. From the
linguistics point of view, according to some researchers, further exploration
of the notion of verb classes is needed for real-world tasks such as machine
translation, language generation, and document classification. Accordingly,
this non-linguistics study may benefit linguistics.
