Abstract:

The need for locating information by subject goes back a long way, but has grown even more with the automation of library catalogues and with the explosion of Internet-based resources as well, as people are performing high volumes of subject searching The above-mentioned problems concerning subject retrieval start in the very first stage: the information request. Users have a tendency towards limiting themselves in their requests. They are frequently conditioned by their current knowledge, asking only for the kind of information they already know. On the other hand, they often confuse what they need with what they want, and they want much more than they really need, but request nothing about what they do not already know.
