Information retrieval and the user's profile. Critical aspects

The paper presents the quality services improvement for every type of user in the university library and their utility. The users' profile contains information about the users, which is connected with its informational necessities. The profiles were used as models for possible types of questions (queries) since the appearance of the systems for the redeeming of information. Many efforts have been done recently for the integration of the profiles used and questions in more satisfying systems. Many systems of current awareness are based on the easy profiles. This type of profile is easier to compare with the new documents than any other complex profile; in the same time it clears away the developing of a sophisticated profile.
