POPL 2023 Call for Papers (https://popl23.sigplan.org/) PACMPL Issue POPL 2023 seeks contributions on all aspects of programming languages and programming systems, both theoretical and practical. Authors of papers published in PACMPL Issue POPL 2023 will be invited to present their work in the POPL conference in January 2023, which is sponsored by ACM SIGPLAN, in cooperation with ACM SIGACT and ACM SIGLOG. # Important Dates Thu 07 Jul 2022: Submission Deadline Tue 06 Sep 2022: Start of Author Response period Fri 09 Sep 2022: End of Author Response period Tue 27 Sep 2022: Notification of Conditional Acceptance Wed 26 Oct 2022: Deadline for submission of revisions Mon 07 Nov 2022: Notification of Final Acceptance Thu 10 Nov 2022: Camera-Ready Deadline Wed 18 - Fri 20 Jan 2023: Conference For the fiftieth POPL and the 50th anniversary of POPL, we will be back where POPL #1 happened: Boston, Massachusetts. Location: Boston Park Plaza, Boston, USA General chair: Andrew Myers Program chair: Amal Ahmed Program Committee members: https://popl23.sigplan.org/committee/POPL-2023-popl-research-papers-program-... Full CFP: https://popl23.sigplan.org/track/POPL-2023-popl-research-papers#POPL-2023-Ca... NEW THIS YEAR: POPL 2023 will use a double-blind reviewing process (instead of the lightweight double-blind process used in recent years). This means that identities of authors will not be visible to reviewers until after acceptance decisions have been made. For authors, the main change is that there is no option to upload non-anonymized supplementary material; only anonymized supplementary material may be submitted. # Scope Principles of Programming Languages (POPL) is a forum for the discussion of all aspects of programming languages and programming systems. Both theoretical and experimental papers are welcome, on topics ranging from formal frameworks to experience reports. We seek submissions that make principled, enduring contributions to the theory, design, understanding, implementation, or application of programming languages. # Evaluation Criteria The Review Committee will evaluate the technical contribution of each submission as well as its accessibility to both experts and the general POPL audience. All papers will be judged on significance, originality, relevance, correctness, and clarity. Each paper must explain its scientific contribution in both general and technical terms, identifying what has been accomplished, explaining why it is significant, and comparing it with previous work. Advice on writing technical papers can be found on the SIGPLAN author information page. Deadlines and formatting requirements will be strictly enforced. # Evaluation Process NEW THIS YEAR: POPL 2023 will use a double-blind reviewing process (instead of the lightweight double-blind process used in recent years). This means that identities of authors will not be visible to reviewers until after conditional-acceptance decisions have been made. For authors, the main change is that there is no option to upload non-anonymized supplementary material; only _anonymized_ supplementary material may be submitted. Also new this year: POPL 2023 will have three Associate Chairs who will help the PC Chair monitor reviews, solicit external expert reviews for submissions when there is not enough expertise on the committee, and facilitate reviewer discussions. As in previous years, authors will have a multi-day period to respond to reviews, as indicated in the Important Dates table. Responses are optional. A response must be concise, addressing specific points raised in the reviews; in particular, it must not introduce new technical results. Reviewers will write a short reaction to these author responses. The Review Committee (RC) will discuss papers electronically and, new this year, also during two days of synchronous, face-to-face, virtual Review Committee meetings. There will be no physical RC meeting; this will avoid the time, cost, and environmental impact of transporting an increasingly large committee to one point on the globe. There is no formal External Review Committee, though experts outside the committee will be consulted. Reviews will be accompanied by a short summary of the reasons behind the committee's decision with the goal of clarifying the reasons behind the decision. To conform with ACM requirements for journal publication, all POPL papers will be conditionally accepted; authors will be required to submit a short description of the changes made to the final version of the paper, including how the changes address any requirements imposed by the Review Committee. That the changes are sufficient will be confirmed by the original reviewers prior to acceptance to POPL. Authors of conditionally accepted papers must submit a satisfactory revision to the Review Committee by the requested deadline or risk rejection. # Double-Blind Reviewing POPL 2023 will use double-blind reviewing. This means that author names and affiliations must be omitted from the submission. Additionally, if the submission refers to prior work done by the authors, that reference should be made in third person. These are firm submission requirements. Any supplementary material must also be anonymized. The FAQ on Double-Blind Reviewing(https://popl23.sigplan.org/track/POPL-2023-popl-research-papers#FAQ-on-Doubl...) clarifies the policy for the most common scenarios. But there are many gray areas and trade-offs. If you have any doubts about how to interpret the double-blind rules, please contact the Program Chair. Make sure to contact the Program Chair for complex cases that are not fully covered by the FAQ. # Submission Guidelines The following two points are easy to overlook: - Conflicts: Each author of a submission has to log into the submission system and properly declare all potential conflicts of interest in the author profile form. A conflict caught late in the reviewing process leads to a voided review which may be infeasible to replace. - Anonymity: POPL 2023 will employ a double-blind reviewing process. Make sure that your submitted paper is fully anonymized. Prior to the paper submission deadline, the authors will upload their full anonymized paper. Each paper should have no more than 25 pages of text, excluding bibliography, using the new ACM Proceedings format. # Artifact Evaluation for Accepted Papers Authors of conditionally accepted papers will be invited to formally submit supporting materials to the Artifact Evaluation process. Artifact Evaluation is run by a separate committee whose task is to assess how the artifacts support the work described in the papers. Artifact submission is strongly encouraged but voluntary and will not influence the final decision regarding the papers. Papers that go through the Artifact Evaluation process successfully will receive a seal of approval printed on the papers themselves. Authors of accepted papers are encouraged to make these materials publicly available upon publication of the proceedings, by including them as "source materials" in the ACM Digital Library. # Copyright, Publication, and Presentation As a Gold Open Access journal, PACMPL is committed to making peer-reviewed scientific research free of restrictions on both access and (re-)use. Authors are strongly encouraged to support libre open access by licensing their work with the Creative Commons Attribution 4.0 International (CC BY) license, which grants readers liberal (re-)use rights. Authors of accepted papers will be required to choose one of the following publication rights: - Author licenses the work with a Creative Commons license, retains copyright, and (implicitly) grants ACM non-exclusive permission to publish (suggested choice). - Author retains copyright of the work and grants ACM a non-exclusive permission to publish license. - Author retains copyright of the work and grants ACM an exclusive permission to publish license. - Author transfers copyright of the work to ACM. These choices follow from ACM Copyright Policy and ACM Author Rights, corresponding to ACM's "author pays" option. While PACMPL may ask authors who have funding for open-access fees to voluntarily cover the article processing charge (currently, US$400), payment is not required for publication. PACMPL and SIGPLAN continue to explore the best models for funding open access, focusing on approaches that are sustainable in the long-term while reducing short-term risk. All papers will be archived by the ACM Digital Library. Authors will have the option of including supplementary material with their paper. The official publication date is the date the proceedings are made available in the ACM Digital Library. This date may be up to two weeks prior to the first day of the conference. The official publication date affects the deadline for any patent filings related to published work. Authors of accepted papers are required to give a short talk (roughly 25 minutes long) at the conference, according to the conference schedule. # Distinguished Paper Awards At most 10% of the accepted papers of POPL 2023 will be designated as Distinguished Papers. This award highlights papers that the POPL Review Committee thinks should be read by a broad audience due to their relevance, originality, significance and clarity. The selection of the distinguished papers will be made based on the final version of the paper and through a second review process.
