Competition 2: Finnish


Table: The obtained average precision (AP%) in the information retrieval task for the submitted segmentations in Finnish. Methods without authors are reference methods by the organizers. Indexing is performed using Okapi (BM25) weighting for all morphemes except the most common ones (stoplist) with corpus frequency higher than 75,000. Asterisk (*) denotes submissions that did not include segmentations for Competition 2 and were evaluated by using the smaller Competition 1 wordlist.
