Abstract: The paper addresses the problem of automatic identification of phrases to be included in back-of-book indexes. We analyzed books in Polish and English published with subject indexes compiled by their authors. We checked what kinds of phrases are placed in those indexes and how often they actually occur in the corresponding books. In the experiments, we use existing terminology and keyphrase extraction tools. For Polish, the first tool is better than the second one, but for English texts, the results are inconclusive.
