The International Journal of Artificial Intelligence for Science (IJAI4S) is established to address the growing role of artificial intelligence (AI) in scientific research. As AI technologies continue to advance, they are increasingly applied across various scientific domains, including physics, chemistry, biology, medicine, environmental science, and engineering. However, many traditional academic journals often categorize AI research strictly within computer science, overlooking its transformative impact on scientific discovery. IJAI4S aims to bridge this gap by providing a dedicated platform for high-quality interdisciplinary research that integrates AI with scientific challenges. This journal fosters innovation by accepting both applied AI research in scientific domains and fundamental AI algorithmic developments with scientific relevance. It upholds rigorous academic standards through a double-blind peer review system, ensuring contributions meet the highest levels of scientific integrity, reproducibility, and impact. As an open-access journal, IJAI4S is committed to broad knowledge dissemination, enabling researchers worldwide to access and build upon published findings freely. With a vision to become a leading journal in AI for Science, IJAI4S actively promotes international collaborations, organizes conferences and workshops, and recognizes outstanding contributions through annual best paper awards. By fostering a dynamic research community, the journal aims to accelerate AI-driven scientific advancements and shape the future of intelligent research methodologies. We invite scholars from diverse disciplines to submit their work and collaborate in driving forward the integration of AI in science.
