Automated Topic–Document Matching Pipeline for Systematic Literature Reviews

This code operationalises a computational screening and classification stage of a systematic literature review (SLR). Specifically, it replaces manual thematic assignment with a reproducible, transparent, and auditable workflow. The code is an automated text-mining and topic-matching pipeline designed to support systematic literature reviews by algorithmically aligning full-text research articles with pre-defined LDA topics using semantic similarity and keyword validation.
