Knowledge and Natural Language Processing Track @ ACM-SAC
Aim of the Knowledge and Natural Language Processing (KNLP) track at ACM SAC is to investigate techniques and application of knowledge engineering and natural language processing, focusing in particular on approaches combining them. This is an extremely interdisciplinary emerging research area, at the core of Artificial Intelligence, combining and complementing the scientific results from Natural Language Processing and Knowledge Representation and Reasoning.

Paper Submission
Submissions must not have been published or be concurrently considered for publication elsewhere. Papers should be submitted in PDF using the ACM-SAC proceedings format. Authors’ names and affiliations should be entered separately at the submission site and not appear in the submitted papers. Each submission will be reviewed in a DOUBLE-BLIND process according to the ACM-SAC Regulations. Student Research Competition (SRC) submissions are welcome (see SAC 2026 SRC page for details).
Initial Submission Policy
All submissions must initially be submitted as regular papers. There is no separate submission track for poster papers.
Paper selection is based on originality, technical contribution, presentation quality, and relevance to the Knowledge and Natural Language Processing Track.
Based on the outcome of the review process, some submissions—although technically sound—may not be accepted as regular papers due to overall acceptance rate constraints, and could be accepted as posters
Minimum Length for Review Consideration
While there is no formal minimum page requirement, submissions of fewer than four (4) full pages that do not demonstrate substantial contributions may be subject to desk rejection without external review.
Camera-ready Page Limits
Regular Papers (accepted for publication):
Up to eight (8) pages are included with standard registration.
Poster Papers (recommended for acceptance):
Up to two (2) pages are included with standard registration.
Important Dates (check SAC website for up-to-date dates)
