Introduction:
Evidence-based development of healthcare innovations requires efficient access to existing knowledge. The Innovation Committee of the Federal Joint Committee (Gemeinsamer Bundesausschuss, G-BA) has funded more than 800 projects since 2016, yet the heterogeneity of topics and terminology limits the effectiveness of the current keyword-based search interface.
Methods:
To address vocabulary-mismatch problems and support more nuanced information needs, we developed and evaluated a semantic search tool using vector-based natural-language retrieval. The application embeds project descriptions and user queries and computes similarity directly in the browser, enabling privacy-preserving, offline operation. In a controlled comparative study with three experienced users, we assessed efficiency and effectiveness across four standardized search tasks.
Results:
Although based on a small sample size, the results indicate that semantic retrieval can meaningfully improve the discovery of projects funded by the Innovation Committee and support evidence-based research workflows.
Conclusion:
Future work should validate these findings in larger cohorts and explore enhanced ranking strategies.

Decision Making: P-value Method
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
