    Abstract
    The present paper is devoted to two directions in algorithmic classificatory procedures: the journal co-citation analysis as an example of citation networks and lexical analysis of keywords in the titles and texts. What is common to those approaches is the general idea of normalization of deviations of the observed data from the mathematical expectation. The application of the same formula leads to discovery of statistically significant links between objects (journals in one case, keywords - in the other). The results of the journal co-citation analysis are reflected in tables and map for field "Women's Studies" and for field "Information Science and Library Science". An experimental attempt at establishing textual links between words was carried out on two samples from SSCI Data base: (1) EDUCATION and (2) ETHICS. The EDUCATION file included 2180 documents (of which 751 had abstracts); the ETHICS file included 807 documents (289 abstracts). Some examples of the results of this pilot study are given in tabular form . The binary links between words discovered in this way may form triplets or other groups with more than two member words.

    Abstract
    Predicting relevance of documents from citations is a common problem for information users. The study addresses the relevance prediction process and most specifically, what is viewed by the subject while using the citations. 2 kinds of protocols were collected while 11 subjects viewed 7 citations each. Eye fixations and eye movements between parts of citations were examined. Verbal reports from subjects during this process were used to explore the process of assessment
