10 Questions
What is the purpose of the matching threshold $m$ in Algorithm 1 of SemSeed?
It determines the minimum required similarity between the seeding location and the bug-to-imitate.
What is the key difference between a semantics-aware and a semantics-unaware variant of SemSeed?
The semantics-unaware variant does not handle unbound tokens.
What does the blue curve in Figure 3 represent?
The percentage of seeded bugs out of all bugs that a purely syntactic variant of SemSeed creates.
What is the key application of SemSeed explored in the text?
Generating training data for learning-based bug detection.
What percentage of bug seeding patterns are missed when unbound tokens are not handled?
62%
What is the main purpose of the SemSeed approach described in the text?
To create realistic bug seeding patterns for training and evaluation.
What is the key difference between a matching threshold of 0 and a matching threshold of 1 in SemSeed?
A threshold of 0 means the seeding location need not be similar to the bug-to-imitate, while a threshold of 1 requires perfect similarity.
What is the key advantage of the semantics-aware variant of SemSeed over the semantics-unaware variant?
The semantics-aware variant does not miss any bug seeding patterns due to unbound tokens.
How does the matching threshold $m$ influence the bugs that SemSeed creates, according to Figure 3?
A higher matching threshold $m$ results in a higher percentage of seeded bugs out of all bugs.
What is the key difference between the SemSeed approach and the DeepBugs approach mentioned in the text?
SemSeed is used to evaluate the usefulness of semantic bug seeding, while DeepBugs is used to build the learning-based bug detection model.
Test your knowledge on the criteria for discarding bug seeding patterns in software development, based on token count and frequency of occurrence. Understand how a threshold is set to avoid learning obscure patterns with low applicability.
