  Software analytics can be improved by surveying; i.e. rechecking and
(possibly) revising the labels offered by prior analysis. Surveying is a
time-consuming task and effective surveyors must carefully manage their time.
Specifically, they must balance the cost of further surveying against the
additional benefits of that extra effort. This paper proposes SURVEY0, an
incremental Logistic Regression estimation method that implements cost/benefit
analysis. Some classifier is used to rank the as-yet-unvisited examples
according to how interesting they might be. Humans then review the most
interesting examples, after which their feedback is used to update an estimator
for estimating how many examples are remaining. This paper evaluates SURVEY0 in
the context of self-admitted technical debt. As software project mature, they
can accumulate "technical debt" i.e. developer decisions which are sub-optimal
and decrease the overall quality of the code. Such decisions are often
commented on by programmers in the code; i.e. it is self-admitted technical
debt (SATD). Recent results show that text classifiers can automatically detect
such debt. We find that we can significantly outperform prior results by
SURVEYing the data. Specifically, for ten open-source JAVA projects, we can
find 83% of the technical debt via SURVEY0 using just 16% of the comments (and
if higher levels of recall are required, SURVEY0can adjust towards that with
some additional effort).
