A Meta-Synthesis of Review Studies on Wood–Polymer Composites: Mapping the Current Research Landscape

By extracting terms from different sections of each manuscript and then standardizing synonyms into canonical labels, the framework based the vocabulary on what the investigated publications “do” (i.e., methods, results, and applications), rather than on citation-based proxies. This section-aware, canonicalized term set proved to be both more accurate and more comparable across studies, enabling clearer clustering and more precise trend analysis. Since each term links back to its source section, the map is auditable and reproducible, thereby improving the interpretability of the results. Adopting the proposed Methodological Framework for Key Terms Mapping (MFKTM) significantly enhanced the topical accuracy of our analysis compared to using Keywords Plus or even Author Keywords.
