RusLICA: A Russian-Language Platform for Automated Linguistic Inquiry and Category Analysis

TL;DR

This paper presents RusLICA, a novel Russian-language platform for automated linguistic analysis that adapts LIWC methodology to Russian, incorporating linguistic, statistical, and model-based features for psycholinguistic research.

Contribution

It introduces a Russian-specific LIWC adaptation with 96 categories, combining linguistic resources and pre-trained language models for comprehensive text analysis.

Findings

Developed a Russian LIWC dictionary with 96 categories

Implemented a web-based analyzer as part of RusLICA

Mapped lemmas to 42 psycholinguistic categories

Abstract

Defining psycholinguistic characteristics in written texts is a task gaining increasing attention from researchers. One of the most widely used tools in the current field is Linguistic Inquiry and Word Count (LIWC) that originally was developed to analyze English texts and translated into multiple languages. Our approach offers the adaptation of LIWC methodology for the Russian language, considering its grammatical and cultural specificities. The suggested approach comprises 96 categories, integrating syntactic, morphological, lexical, general statistical features, and results of predictions obtained using pre-trained language models (LMs) for text analysis. Rather than applying direct translation to existing thesauri, we built the dictionary specifically for the Russian language based on the content from several lexicographic resources, semantic dictionaries and corpora. The paper describes the process of mapping lemmas to 42 psycholinguistic categories and the implementation of the analyzer as part of RusLICA web service.
