Abstract  By the term “scientific breakthroughs,” we mean innovations that are relatively transformative and have a profound impact on the future direction and trends of a disciplinary field. A scientific breakthrough aims to reveal new phenomena and laws that have emerged earlier but have not yet been recognized or investigated formally. Identifying scientific breakthroughs at an earlier stage can provide decision support to policymakers and granting agencies in optimizing resource allocation. This study selected the field of Gene Engineered Vaccine for empirical research—focusing on weak association linkages in knowledge networks—and constructed a multi-layer network based on subject term co-occurrence, author co-authorship, and reference co-citation relationships. Thereafter, we analyzed the association information between multiple feature items to mine the subject content and evaluated the recognition effect with the help of expert judgment and authoritative reports. The comparative analysis with the identification results based on strong correlation relationships verified that the method constructed in this study is applicable to the early identification of scientific breakthroughs. Future research could draw on network representation learning and introduce temporal networks to pinpoint the moment when a breakthrough is made to fade away.
