The article deals with the contextual funnel method for indirect analysis of socio-emotional processes inuser-generated media texts. The focus is made on the measurability of cultural and contextual narrativesrepresented in media texts, with the study of loneliness serving as a starting parameter for demonstrating themethod. The material consists of 457 posts from r/Replika (n = 245) and r/CharacterAI (n = 212) communities(Reddit, March 2026). The funnel successively narrows the corpus from a broad set to a relevant subcorpus,separating the zero-relevance zone, through eight filtering steps at contextual and linguistic levels. As a result ofthe method application, the contextual zone of loneliness was identified, covering 33.3 % of the corpus (152 outof 457 posts). The cross-validated subcorpus comprised 41 texts (9.0 %), while the zero-relevance zone included19 posts (4.2 %). Inter-coder agreement reached Cohen's κ = 0.89–1.00 across the funnel steps. The studyanalyses media texts as cultural artefacts rather than diagnosing users' psychological states: the contextual zoneindicates the frequency of thematic presence in narratives, not the prevalence of loneliness in the population. Theproposed method enables the formation of thematic dictionaries for assessing narrative content in media texts;however, its transfer to other platforms, languages, and subject areas requires independent validation of thecorresponding dictionaries and coding schemes.
