Research on Life Cycle Assessment (LCA) is being conducted in various sectors, from analyzing building materials and components to comprehensive evaluations of entire structures. However, reviews of the existing literature have been unable to provide a comprehensive overview of research in this field, leaving scholars without a definitive guideline for future investigations. This paper aims to fill this gap, mapping more than twenty years of research. Using an innovative methodology that combines social network analysis and text mining, the paper examined 8024 scientific abstracts. The authors identified seven key thematic groups, building and sustainability clusters (BSCs). To assess their significance in the broader discourse on building and sustainability, the semantic brand score (SBS) indicator was applied. Additionally, building and sustainability trends were tracked, focusing on the LCA concept. The major research topics mainly relate to building materials and energy efficiency. In addition to presenting an innovative approach to reviewing extensive literature domains, the article also provides insights into emerging and underdeveloped themes, outlining crucial future research directions.

翻译：生命周期评估（LCA）研究已在多个领域展开，涵盖从建筑材料与构件的分析到建筑整体的综合评价。然而，现有文献综述未能系统呈现该领域的研究全貌，使得学者缺乏指导未来研究的明确框架。本文旨在填补这一空白，梳理超过二十年的研究脉络。通过结合社交网络分析与文本挖掘的创新方法，本文分析了8024篇科学摘要。作者识别出七个关键主题群，即建筑与可持续性集群（BSCs）。为评估其在建筑与可持续性宏观讨论中的重要性，研究应用了语义品牌价值（SBS）指标。此外，本文追踪了以LCA概念为核心的建筑与可持续性发展趋势。主要研究议题集中于建筑材料与能源效率领域。除提出一种综述广泛文献领域的创新方法外，本文亦揭示了新兴与欠发展主题，为未来关键研究方向提供了重要指引。
