Welcome to SPIRE 2021

SPIRE 2021 is the 28th edition of the annual Symposium on String Processing and Information Retrieval. SPIRE has its origins in the South American Workshop on String Processing, which was first held in Belo Horizonte, Brazil, in 1993. Since 1998 the focus of the workshop has also included information retrieval, due to its increasing relevance to and inter-relationship with string processing.

SPIRE 2021 will be held in Lille, France.

Covid-19: We are carefully watching the situation with the Covid-19 pandemic. We aim to conduct a hybrid event, offering the possibility to attend the conference either in person or virtually. In the worst case, SPIRE 2021 will be held 100% online.
