Introduction

As you know, the dictionary consists of dictionary articles, is a certain set of them. If the dictionary is built according to the canons of lexicographic science, then it has a certain structure to which all its dictionary articles are subject. Usually the structure of dictionary articles is described in the preface to the dictionary. But between different dictionary entries of the same dictionary there are many connections, relations, reflections, which reflect the content of the subject area that is the object of lexicography, and these relations are usually implicit. However, they are very important for users and those who want to use the dictionary to conduct their own research and create new dictionaries. Partially mentioned structural vocabulary effects are described in the works [2,4,6]. General theory of dictionary structures -the theory of lexicographic systems was created by V. A. Shirokov in the 90s of last century; The most complete presentation of this theory and its applications is published in the seven-volume edition "Linguistic and Information Studies", which is available for free on the website of the Ukrainian Linguistic Portal at https://www.ulif.org.ua/publication. In our work we will follow the principles of this theory.

It is important to distinguish between the most formal model and the XML scheme (coding scheme). That is, it is necessary to consider the form and content of lexical information in the abstract, regardless of the requirements and restrictions imposed on its final presentation as a coded or printed object [7,8]. This process is important, because dictionaries can be coded not only for the purposes of publication in printed (book) or electronic form (website), but also to create computational lexicons. Therefore, it is very important to develop a model that can later be transformed into a variety of alternative formats [3].

In this paper, we outline the following stages:

1. Lexicographic system (L-system) development of dictionary structure 2. Marking the text of the Dictionary with XML tags according to the structure of its L-system (XML document)

Using the examples of dictionary articles of the selected dictionary, we will demonstrate how the XML schema can be applied to any dictionary article. Due to its generality, we believe that our model can serve as a basis for presenting, combining and extracting information not only from dictionaries of the same type, but also from a wide range of terminological dictionaries [5].

The steps

Lexicographic system development of Dictionary of Ukrainian biological terminology (SUBT)

We introduce the notation: АВ it will mean, that А  В. Then, following the theory of lexicographic systems [ 2 ], the structure of the L-system of SUBT is presented in the form: Lexical information in dictionary articles can be represented in the form of a tree structure, which largely reflects the natural hierarchical organization of entries in printed dictionaries. Consider the examples in the notation of the scheme:

Example 1.

вy#са, -ів, мн., одн. вус, -а (рос. усы#, ед. ус., англ. whisker (у тварин), tendril (у рослин), moustache (у людини), antenna (у комах)) 1. Загальна назва розміщених біля рота чутливих волосин (вібрисів) у ссавців та щетинкоподібного пір'я у птахів, деякі дотикові утвори у безхребетних тварин; 2. Надземні виткі прикріплювальні пагони у рослин.

Marking

Representation Надземні виткі прикріплювальні пагони у рослин.

In the example, there is only one terminology block and one semantic block, respectively. It was found that in dictionary articles there are as many terminological blocks as semantic ones and vice versa. There are two Ukrainian complexes in the terminological block. Presented as: вy#са, -ів, мн.; одн. вус, -а. In the semantic block there can be some interpretations in an example of them two are found: The semantic block can be filled with blocks of terminological phrases, synonyms, blocks of references. Terminological blocks can be several, they can be presented in one or two complexes. The examples illustrate some variants of the structure in the notation of the scheme.

Marking the text of the Dictionary with XML tags according to the structure of its L-system (XML document)

The next stage is the automatic conversion of the lexicographic structure of the dictionary into an XML document. However, it is obvious that the XML file explains and stores all the structural elements we have identified and the relationships between them. This is done using a special software procedure developed by us to automatically mark the text of the dictionary. The marking algorithm is developed based on polygraphic features of text identification of structural elements of the L-system (boundaries of the dictionary article (paragraphs), special symbols, positional characteristics, changes of language, fonts, case of letters, etc.). The transition to an XML document is due to the need to define author tag sets and attribute names. Document XML structures can also be nested, providing any level of hierarchy, as long as the rules for embedding XML documents are followed. XML documents can contain any optional grammar descriptions of the document so that other programs can check its structure. The XML representation of the dictionary obtained in this way makes it possible to form its lexicographic database in automatic mode. This stage will be considered in a separate paper.
