2020 Principle and Practice of Data and Knowledge Acquisition Workshop (PKAW2020), July 11-12, 2020, Yokohama, Japan

PKAW2020 is a workshop under IJCAI/PRICAI2020


PKAW (Principle and Practice of Data and Knowledge Acquisition Workshop) was established in 1980s as an integral part of PRICAI (Pacific Rim International Conference on Artificial Intelligence). PKAW2020 will be held as a workshop of the joint conference IJCAI-PRICAI2020 at Yokohama, Japan. Wide range of topics such as knowledge acquisition, data representation and big data acquisition etc. are greatly welcome.

PKAW will not accept any paper that, at the time of submission, is under review for, has already been published in, or has already been accepted for publication in, a journal or another venue with formally published proceedings. If part of the work has been previously published, authors are strongly encouraged to cite and compare/contrast the new contributions with the parts that were already published before. The paper must substantially extend the previously published work.

All papers for the review should be submitted electronically using the conference management tool in PDF/DOC format and formatted using the Springer LNAI template or IJICAI template. The paper should be between 10 to 15 pages long. Camera ready for accepted papers should be submitted using only the Springer LNAI template. For Springer LNAI format templates, please see the Springer’s website:
