| Popis: | By the means of a flexible machine search system three experiments have been made in order to test the retrieval efficiency of searching free text and keywords. Based upon the relevance judgements of the users, the results indicate that titles and abstracts are good index material which can be used for machine searching without human indexing in the three fields studied. |
