### Comparing Individual Relations  
The most direct way of comparing frequency specters for different sets of texts consists of juxtaposing occurrences of isolated relations. Figure 1 presents this information for the most frequent relations. For a relation R, the ordinate axis shows the percentage of its occurrences among the total number of relation's occurrences in the corresponding set of texts. For instance, the set of poetic texts written by [PERSON] consists of 33 texts (Table 1), the total number of relation's occurrences for these texts is equal to 682, and the percent of conjunctions among these occurrences is equal to 26.39%. The diagram only includes relations with a percentage higher than 3% at least for one of the three authors. The considered sets of texts are the following: the verses written by [PERSON] (the first, blue, lines), by [PERSON] (the second, red, lines), and by [PERSON] (the third, grey, lines). For the first two authors, the sets include both periods of creativity, early and late. The diagram shows relative frequencies for ten types of relations: background, conjunction, elaboration, circumstance, preparation, evaluation, contrast, sequence, comparison, negation.  
The comparison reveals several peculiarities of the considered texts; the discrepancies provide data for distinguishing the author's styles of reasoning. For instance, conjunction is the most characteristic relation for [PERSON]'s style, elaboration and circumstance are mostly characteristic for [PERSON]. [PERSON]. Evaluation, contrast and comparison have the highest values for [PERSON], yet these values are comparatively low for all sets of texts represented by the diagram. The latter suggested an idea of comparing not only isolated relations but also some groups of semantically congenial relations. The next subsection provides the results of such comparisons.  
Figure 1 renders the statistical information about usability of relations in the total amount of poetic texts written by a definite author. However, it does not provide information concerning the probability of a relation appearing in a reasoning.  
Figure 2 presents this information for the most frequent relations. The ordinate axis indicates the percent of verses that use the corresponding relation among the total number of verses in the considered set of texts. It does not matter how many occurrences of a relation are in the same verse. For instance, conjunction is the most frequent relation for the texts written by [PERSON], probability of appearing this relation in a verse is about 0.97; this fact correlates with the previous diagram, where conjunction also proved to be the most characteristic for the [PERSON]. [PERSON]'s texts.  
The diagram (Figure 2) shows that probability of solutionhood appearing in the [PERSON]'s lyrics is the lowest. Evaluation, contrast, appeal, comparison, evidence, and concession often participate in reasoning expressed by the lyrics written by [PERSON]; however, these relations have a substantially lower possibility of occurrence in the verses of the two other poets. For [PERSON], evaluation and evidence are extremely rare. [PERSON] is particularly inclined to use the relation of evaluation, the probability of this relation appearing in his text is about 0.64; while for [PERSON] it is about 0.03 and for [PERSON] about 0.27.
