Qualitative and Quantitative Markers of Individual Authorial Conceptualization Olena Levchenko, Marianna Dilai Lviv Polytechnic National University, 12 Bandera Str., Lviv, 79013, Ukraine Abstract This paper proposes a methodology of idiolect/idiostyle research based on identifying quantitative and qualitative markers of individual authorial conceptualization. We present statistical and metaphorical profiles of the concept of СМУТОК (SADNESS) [SMUTOK] in Ukrainian, in general, in the corpus of fiction texts, and also in the idiolects of individual writers. The functioning of the verbalizers of the concept in the writers’ texts is analyzed by means of statistical data grouping, dividing the population into homogeneous groups based on a certain feature. Furthermore, we address the specificity of the metaphorization of the studied concept and focus on the metaphorical attributes of the concept's verbalizers. The data for this research were collected from GRAC-15. Keywords 1 Idiolect, statistics, metaphorization, concept of СМУТОК (SADNESS) [SMUTOK], Ukrainian fiction, GRAC. 1. Introduction With the rapid development of corpus linguistics, stylometric studies, in particular, of the idiolect, have intensified [1, 2, 3, 4, 5, 6, 7, 8]. Obviously, stylometry is mainly based on mathematical calculations of the frequency of occurrence of certain words and parts of speech in the text, as well as estimating of their average length and mutual proportion [9]. However, Martyna Grądziel notes that corpus linguistics is based on comparing the utterance under study with the linguistic norm present in the texts of corpora containing the most common ways of using specific words or sentence structures in society along with the most frequently attributed meanings, and after such comparison, conclusions are drawn about the peculiarities of the author's text [10]. The search for a system of idiostyle markers is ongoing, in particular in forensic science [11, 12]. It should be noted that among such markers J. Olsson mentions idioms (curious phrasing can be significant) [12]. Researchers also use multivariate methods to find similarities between texts [13, 14, 15, 16]. This paper presents a comprehensive study of qualitative and quantitative markers of individual authorial conceptualization. In view of the significance of metaphor in a broad sense, an attempt has been made to analyze the statistical (quantitative and qualitative parameters of single-component verbalizers of the concept) and metaphorical (quantitative and qualitative parameters of multicomponent compounds) profiles of the concept of СМУТОК (SADNESS) [SMUTOK] in Ukrainian both on the basis of texts of the literary style and in the idiolects of individual writers. In order to conduct the research, we created a number of subcorpora in GRAC-15, including subcorpora of fiction, as well as subcorpora of texts by a number of writers (Y. Andrukhovych, Y. Vynnychuk, I. Vilde, O. Zabuzhko, I. Karpa, A. Kokotiukha, V. Lys, M. Matios, H. Pahutyak, I. Rozdobudko, A. Chekh, V. Shklyar).
