Specification for BIO tags: "{{"B-short"}}" and "{{"I-short"}}" represent respectively the beginning and intermediate tokens for abbreviations (acronyms)."{{"B-long"}}" and "{{"I-long"}}" represent respectively the beginning and intermediate tokens for expansions of abbreviations (acronyms meaning). All other tokens are represented by "{{"O"}}". Given the space-separated tokens below, write down for each token the corresponding BIO tag. Use a space to separate tags in the answer.
