<div dir="ltr"><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:normal;font-size:12pt"><font face="arial, sans-serif">As Artificial Intelligence systems increasingly rely on both language understanding and structured knowledge, bridging Natural Language Processing and Knowledge Engineering has become a central challenge for the next generation of intelligent systems. The rapid evolution of Large Language Models and knowledge-based AI is creating new opportunities—and new challenges—in how machines acquire, represent, connect, and reason over knowledge. Understanding language alone is no longer enough: modern AI systems must also be able to organize knowledge, integrate it with linguistic information, and use it effectively to support reasoning. As a result, the relationship between language, knowledge, and reasoning has emerged as one of the key research frontiers in contemporary Artificial Intelligence.<b style=""><span lang="EN-US" style="font-size:18pt"></span></b></font></p><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:normal;font-size:12pt"><span lang="EN-US" style=""><font face="arial, sans-serif">The Knowledge and Natural Language Processing (KNLP) Track at the ACM Symposium on Applied Computing investigates methods and applications at the intersection of <b>Knowledge Engineering</b> and <b>Natural Language Processing</b>, with particular emphasis on approaches that combine these two areas.</font></span></p><p class="MsoNormal" style="margin:0cm 0cm 8pt;line-height:normal;font-size:12pt"><span lang="EN-US" style=""><font face="arial, sans-serif">KNLP is an emerging and highly interdisciplinary research field at the core of Artificial Intelligence.
