In many academic fields, particularly computer science, artificial intelligence, and engineering, conferences are ranked in tiers to reflect their prestige and selectivity. These rankings are not official but are widely recognized by universities and research institutions. The most common system uses an A, B, and C classification, where "A" is the highest tier.
The tier of a conference is determined by several factors, including its acceptance rate, the quality of its peer review, and its reputation in the research community.
These are the most prestigious conferences in a field. Publishing a paper here is considered a major achievement and is often a requirement for tenure and promotion at top universities.
Acceptance Rate: Typically very low, often below 20%.
Quality of Papers: The papers published are highly original, technically rigorous, and often set the standard for future research in the field.
Reputation: The best-known conferences in a discipline are A-tier, attracting leading researchers and keynote speakers.
Examples: CVPR (Computer Vision), NeurIPS (AI/Machine Learning), SIGCOMM (Computer Networks).
These conferences are also highly respected and are often seen as a step below the top-tier. Publishing here is still a significant accomplishment.
Acceptance Rate: Moderately selective, usually between 25% and 40%.
Quality of Papers: Papers are solid, original contributions, but may be more focused on a specific sub-field or a smaller advance than a major A-tier paper.
Reputation: These are well-established conferences that provide an excellent platform for researchers to present quality work.
C-tier conferences are important for disseminating new ideas, works in progress, or niche research that may not fit a higher-tier conference's scope.
Acceptance Rate: Higher than B-tier conferences, often above 50%.
Quality of Papers: The papers may be less mature or focus on a very narrow topic. They are still peer-reviewed, but the bar for acceptance is lower.
Reputation: These conferences are good for graduate students or researchers who want to get early feedback on their work and practice their presentation skills.
Conference rankings are not officially issued by a single organization. Instead, they are typically developed by professional societies, university committees, or independent research groups that survey academics in a specific field. It's a form of community consensus that reflects the collective opinion on a conference's prestige.
Before submitting your paper, check your university's internal guidelines or a well-known ranking list in your field to understand where a particular conference stands. This will help you make an informed decision and align your publication strategy with your career goals.
