If you're encountering the misspelling "acm/ieee-xs", here are a few possible corrections. The correct term could be "ACM/IEEE-CS", which refers to the Association for Computing Machinery and the Institute of Electrical and Electronics Engineers - Computer Society. Alternatively, "ACM/IEEE Xplore" might be a more appropriate term if you are referring to their joint digital library for research articles. Both options are commonly used in the field of computer science.
