6 CONCLUSIONS AND FURTHER
WORK
The present paper has described a tool that supports
a methodology that aims to accelerate the production
of analysis and early design models. This
methodology is based on semantic abstraction of
linguistic elements and involves the use of the
semantic role theory and a semi-natural language.
The prototype tools have produced good results with
problems described in no more than eight sentences
and 100 words on an average. Observed advantages
of the use of this tool are formalization, standard
notation, validation, traceability, efficiency and early
identification of misunderstood requirements.
Individuals using it, will see how a group of
sentences describing a problem are handled by
GOOAL. The system takes decisions with minimal
user participation, shows its interpretation in 4WL
and produces model views of the problem. Unique
features of this tool are the underlying methodology
and the production of dynamic models. Although the
tool, methodology and techniques expounded here
are far from perfection, results using simple
sentences are promising. Better results are expected
if a more complete general dictionary is used as well
as finer refinements in semantic classification of
verbs into families. With the comparison of results
between both GOOAL tool and the tests we are
running with the students, it can be conclude that we
can use this program as an educative tool.
