TAROT

This the repository for our ASE'2022 paper "Using Consensual Biterms from Text Structures of Requirements and Code to Improve IR-Based Traceability Recovery". In this paper, TAROT is proposed to improve IR-based requirement traceability recovery through using consensual biterms extracted from requirements and code, which can also be combined with other enhancing strategies to promote their performance.

Running TAROT

• Please run main() in Start.java.
• You can choose different evaluated system (9 projects) and IR models (e.g., VSM, LSI, and JSD).

Extract Consensual Biterms

• Step1: Run experiment.preprocess.parsecode.ParseCodeAST to extract identifier names from source code, and experiment.preprocess.biterm.ExtractReqBiterm to extract initial biterms from code.
• Step2: Run methodextractIssueBiterm() and extractUcBiterm() in experiment.preprocess.biterm.ExtractReqBiterm to extract initial biterms from issue and uc respectively.
• Step3: Run experiment.preprocess.biterm.ConsensualBiterm to get consensual biterms both shared by requirements and source code.
