16. Our approach for identifying the common
patterns of developer responses

Step 1:
Collect
metrics
We collected 6 metrics:
Review title length, Review text length, Days since last
release, Review rating, Positive sentiment, Negative
sentiment.

1) What is the impact of responding to user reviews
on the review rating?
3) What drives a developer to respond?
24. Our approach for studying what drives a
developer to respond
24
• We manually read a statistically
representative random sample of user-
developer interaction episodes.
• We study the contents of responses to
understand better what drives developers to
respond to reviews
26. We identified four main drivers for responding
