Static Code Analysis in the AI Era: An In-depth Exploration of the Concept, Function, and Potential of Intelligent Code Analysis Agents
The escalating complexity of software systems and accelerating development
cycles pose a significant challenge in managing code errors and implementing
business logic. Traditional techniques, while cornerstone for software quality
assurance, exhibit limitations in handling intricate business logic and
extensive codebases. To address these challenges, we introduce the Intelligent
Code Analysis Agent (ICAA), a novel concept combining AI models, engineering
process designs, and traditional non-AI components. The ICAA employs the
capabilities of large language models (LLMs) such as GPT-3 or GPT-4 to
automatically detect and diagnose code errors and business logic
inconsistencies. In our exploration of this concept, we observed a substantial
improvement in bug detection accuracy, reducing the false-positive rate to 66\%
from the baseline's 85\%, and a promising recall rate of 60.8\%. However, the
token consumption cost associated with LLMs, particularly the average cost for
analyzing each line of code, remains a significant consideration for widespread
adoption. Despite this challenge, our findings suggest that the ICAA holds
considerable potential to revolutionize software quality assurance,
significantly enhancing the efficiency and accuracy of bug detection in the
software development process. We hope this pioneering work will inspire further
research and innovation in this field, focusing on refining the ICAA concept
and exploring ways to mitigate the associated costs
Solving package dependencies: from EDOS to Mancoosi
Mancoosi (Managing the Complexity of the Open Source Infrastructure) is an
ongoing research project funded by the European Union for addressing some of
the challenges related to the "upgrade problem" of interdependent software
components of which Debian packages are prototypical examples. Mancoosi is the
natural continuation of the EDOS project which has already contributed tools
for distribution-wide quality assurance in Debian and other GNU/Linux
distributions. The consortium behind the project consists of several European
public and private research institutions as well as some commercial GNU/Linux
distributions from Europe and South America. Debian is represented by a small
group of Debian Developers who are working in the ranks of the involved
universities to drive and integrate back achievements into Debian. This paper
presents relevant results from EDOS in dependency management and gives an
overview of the Mancoosi project and its objectives, with a particular focus on
the prospective benefits for Debian
Integration of Quality Attributes in Software Product Line Development
Different
approaches
for
building
modern
software
systems
in
complex
and
open
environments
have
been
proposed
in
the
last
few
years.
Some
efforts
try
to
apply
Software
Product
Line
(SPL)
approach
to
take
advantage
of
the
massive
reuse
for
producing
software
systems
that
share
a
common
set
of
features.
In
general
quality
assurance
is
a
crucial
activity
for
success
in
software
industry,
but
it
is
even
more
important
when
talking
about
Software
Product
Lines
since
the
intensive
reuse
of
assets
makes
the
quality
attributes
(a
measurable
physical
or
abstract
property
of
an
entity)
of
the
assets
to
be
transmitted
to
the
whole
SPL
scope.
However,
despite
the
importance
that
quality
has
in
software
product
line
development,
most
of
the
methodologies
being
applied
in
Software
Product
Line
Development
focus
only
on
managing
the
commonalities
and
variability
within
the
product
line
and
not
giving
support
to
the
non--Âż
functional
requirements
that
the
products
must
fit.
The
main
goal
of
this
master
final
work
is
to introduce
quality
attributes
in
early
stages
of
software
product
line
development
processes
by
means
of
the
definition
of
a
production
plan
that,
on
one
hand,
integrates
quality
as
an
additional
view
for
describing
the
extension
of
the
software
product
line
and,
on
the
other
hand
introduces
the
quality
attributes
as
a
decision
factor
during
product
configuration
and
when
selecting
among
design
alternatives.
Our
approach
has
been
defined
following
the
Model--Âż
Driven
Software
Development
paradigm.
Therefore
all
the
software
artifacts
defined
had
its
correspondent
metamodels
and
the
processes
defined
rely
on
automated
model
transformations.
Finally
in
order
to
illustrate
the
feasibility
of
the
approach
we
have
integrated
the
quality
view
in
an
SPL
example
in
the
context
of
safety
critical
embedded
systems
on
the
automotive
domain.González Huerta, J. (2011). Integration of Quality Attributes in Software Product Line Development. http://hdl.handle.net/10251/15835Archivo delegad
Taming Uncertainty in the Assurance Process of Self-Adaptive Systems: a Goal-Oriented Approach
Goals are first-class entities in a self-adaptive system (SAS) as they guide
the self-adaptation. A SAS often operates in dynamic and partially unknown
environments, which cause uncertainty that the SAS has to address to achieve
its goals. Moreover, besides the environment, other classes of uncertainty have
been identified. However, these various classes and their sources are not
systematically addressed by current approaches throughout the life cycle of the
SAS. In general, uncertainty typically makes the assurance provision of SAS
goals exclusively at design time not viable. This calls for an assurance
process that spans the whole life cycle of the SAS. In this work, we propose a
goal-oriented assurance process that supports taming different sources (within
different classes) of uncertainty from defining the goals at design time to
performing self-adaptation at runtime. Based on a goal model augmented with
uncertainty annotations, we automatically generate parametric symbolic formulae
with parameterized uncertainties at design time using symbolic model checking.
These formulae and the goal model guide the synthesis of adaptation policies by
engineers. At runtime, the generated formulae are evaluated to resolve the
uncertainty and to steer the self-adaptation using the policies. In this paper,
we focus on reliability and cost properties, for which we evaluate our approach
on the Body Sensor Network (BSN) implemented in OpenDaVINCI. The results of the
validation are promising and show that our approach is able to systematically
tame multiple classes of uncertainty, and that it is effective and efficient in
providing assurances for the goals of self-adaptive systems
KAPTUR: technical analysis report
Led by the Visual Arts Data Service (VADS) and funded by the JISC Managing Research Data programme (2011-13) KAPTUR will discover, create and pilot a sectoral model of best practice in the management of research data in the visual arts in collaboration with four institutional partners: Glasgow School of Art; Goldsmiths, University of London; University for the Creative Arts; and University of the Arts London.
This report is framed around the research question: which technical system is most suitable for managing visual arts research data?
The first stage involved a literature review including information gathered through attendance at meetings and events, and Internet research, as well as information on projects from the previous round of JISCMRD funding (2009-11).
During February and March 2012, the Technical Manager carried out interviews with the four KAPTUR Project Officers and also met with IT staff at each institution. This led to the creation of a user requirement document (Appendix A), which was then circulated to the project team for additional comments and feedback. The Technical Manager selected 17 systems to compare with the user requirement document (Appendix B). Five of the systems had similar scores so these were short-listed. The Technical Manager created an online form into which the Project Officers entered priority scores for each of the user requirements in order to calculate a more accurate score for each of the five short-listed systems (Appendix C) and this resulted in the choice of EPrints as the software for the KAPTUR project
