Data-driven software evolution
The SUPERSEDE way
Hamburg Requirements Engineering Symposium
Wednesday, May 23rd, 2018

2. 2
• SUpporting evolution and adaptation of PERsonalized
Software by Exploiting contextual Data and End-user
feedback
• An European funded project (HORIZON 2020 framework, RIA)
• Call: H2020-ICT-2014-1 (Tools and methods for Software
Development)
• Started May 1, 2015 (3 Years) <- JUST ended!
What is SUPERSEDE?
• Consortium: 4
Academic/Research
and 4 Industrial
partners

3. 3
• Software at use …
Software applications and
services increasingly
exploit and generate
data
– sensors embedded in the
environment
– online data sources
– users’ feedback
Motivations:
Observed trends …
• Software development
- The “move fast” trend:
Agile approaches
- Quality & Efficiency:
• software product quality
matters more and more
• taking care of
changing/evolving
customers' needs

4. 4
• Multi-modal feedback / monitoring
• Feedback analysis / Data analytics
• Automated reasoning at support of decision
making in software development
Motivations:
Candidate solutions from research

5. 5
Objective & Approach
Enable a data-driven engineering process
• collect end-users’ feedback and runtime data in an efficient, scalable and adaptable way
• perform an integrated analysis of the collected data for evolution and adaptation decision-making
• support decision-making in the evolution and runtime adaptation of services and applications based on
user’s feedback and contextual data
• enact the decisions made

• Results:
- Found association between types of speech acts (e.g. Informative, Responsive, Requestive,
etc.) and type of issues (e.g. Enhancement, Defect)
- Distribution of speech acts for the first ten comments for Defect and Enhancement, and
identified common patterns
Textual feedback classification
Speech-act & sentiment analysis
Textual online discussion • Techniques:
- NLP techniques for pre-processing
- speech acts and the sentiment as parameters
for training three machine learning algorithms
(Random Forest, J48 and SMO) classify
comments into Enhancement, Feature and
Defect

ECA rule
If the we receive more
than N (e.g. N=2)
feedbacks in the
window’s time frame
an alert is raised for
decision

Rule 1 (R1):
“Two or more negative
feedbacks in 5 min”
Sliding Window R1“I don’t like Y”“I don’t like X”

What’s behind
DMGame
• Automated reasoning:
• Analytic Hierarchy Process (AHP) method that was selected because its
pairwise comparison mechanism allows us to perform a fine-grained analysis of
the motivations that lead to a resulting ranking, thus exploiting at best the
different skills and expertise of the decision makers
• Genetic Algorithms (GA) because it allows to overcome some of the limitations
of AHP, at the cost of a reduced granularity of the ranking
• Gamification
• To foster user engagement, game elements are included, such as:
- Progress, that is user completion rate is reported to each user
- Time Pressure, that is the process has a fixed duration, and actions done after the
process expiration are discarder;
- Pointsification, that is a point attribution mechanism has been designed, with the
purpose of providing an incentive to (i) perform the voting task quickly, and (ii) perform
an accurate
