This thesis investigates patterns of lexico-discursive variation in literary reviews on Instagram and video reviews on YouTube, employing Corpus Linguistics (CL) as a field of language research grounded in real-world usage, and adopting Multidimensional Analysis (MDA) as its lexical methodology. The study addresses key research questions such as: What patterns of variation emerge in the analyzed reviews and video reviews? What underlying discourses are reflected in the set of lexical variables co-occurring in these digital registers—written reviews and video reviews? What ideological discursive formations underpin the linguistic choices of digital literary influencers (DLIs), and how do these choices position them as discursive subjects within the digital domain?Two corpora were analyzed: CLIRI (Corpus of Literary Reviews on Instagram), comprising 517 texts and 144,358 words, and CLIVY (Corpus of Literary Video Reviews on YouTube), consisting of 504 texts and 1,252,978 words. Initially, lexical co-occurrence patterns were identified based on the extracted variables. Factor analysis revealed four primary patterns of variation. The interpretation and labeling of these dimensions indicated the following: (1) Communication and Interactivity versus Introspection and Analysis, (2) Motivation and Cultural Engagement versus Reflection and Existential Realism, (3) Critical and Psychological Analysis versus Historical and Descriptive Contextualization, and (4) Focused Narrative Analysis versus Book Commercialization.The primary hypotheses of the study include: (1) Reviews on Instagram exhibit distinct patterns from video reviews on YouTube, despite addressing the same theme of canonical literature; (2) There is a systematic correlation between lexical features and situational variables in digital registers; (3) The ephemeral and fragmented nature of social networks is not incompatible with the depth and complexity of canonical literature, demonstrating that accessibility can coexist with critical analysis; and (4) The linguistic choices of DLIs reflect specific ideological formations, shaping discursive identities that adapt to the demands of each social media platform. Written reviews on Instagram tend to prioritize a more introspective, analytical, and structured approach, whereas YouTube video reviews are characterized by a focus on interactivity, cultural engagement, and discursive dynamism. This differentiation aligns with studies such as those by Biber and Egbert (2021), which suggest that spoken registers tend to be more fluid and interactive, while written registers typically exhibit greater analytical density and formal organization. By integrating quantitative and qualitative analyses, this research reaffirms the transdisciplinary relevance of Corpus Linguistics and its capacity to describe linguistic variation in digital registers. The study contributes to a deeper understanding of discursive practices in digital environments and underscores the recognition of Corpus Linguistics as an empirical and transdisciplinary Science
