Abstract:
A requirements analysis step plays a significant role on the
development of information systems, and in this step we
produce various kinds of abstract models of the systems
(called requirements models) according to the adopted
development processes, e.g. class diagrams in the case
of adopting object-oriented development. However, constructing
these models of sufficient quality requires highest
intellectual tasks and skills of human requirements analysts.
In this paper, we develop a computerized tool to extract
from a set of Japanese text documents conceptual information,
called conceptual graph, which can be used as
intermediate representation to generate software requirements
models. More concretely, by applying the variation
of text-mining techniques that we have developed, we extract
significant words from text documents referring to
the same problem domain and identify relevant relationships
among them. The extracted words can be considered
as concepts and they are constituents of a conceptual
graph in the domain. This constructed graph can be used
for generating requirements models, e.g. object oriented
models, featuremodel, and even as a domain ontology that
can be utilized during requirements analysis activities. We
have made experimental analyses of our tool. This paper
also includes the discussion on how the extracted conceptual
graph can act as an object-oriented model, a feature
model and a domain ontology, in order to show its wide
applicability.
