Abstract: This paper highlights the evolution and future directions of the SimpleText Track at CLEF, which, over the last few years, fostered an active NLP and IR research community focused on improving access to scientific text. Its benchmarks on scientific passage retrieval, scientific terminology detection and explanation, and scientific text simplification have become standard references. After using a similar setup of the track in 2021–2024, we propose substantial modifications to the track’s structure and tasks. The CLEF 2025 SimpleText track will contain the following three tasks. Task 1 on Text Simplification: Simplify Scientific Text. Task 2 on Controlled Creativity: Identify and Avoid Hallucination. Task 3 on SimpleText 2024 Revisited: Selected Tasks by Popular Request.
