Cross-Lingual Mental Health Ontologies for Indian Languages: Bridging Patient Expression and Clinical Understanding through Explainable AI and Human-in-the-Loop Validation

Ananth Kandala, Ratna Kandala, Akshata Kishore Moharir et al.

Mental health communication in India is linguistically fragmented, culturally diverse, and often underrepresented in clinical NLP. Current health ontologies and mental health resources are dominated by diagnostic frameworks centered on English or Western culture, leaving a gap in representing patient distress expressions in Indian languages. We propose cross-linguistic graphs of patient stress expressions (CL-PDE), a framework for building cross-lingual mental health ontologies through graph-based methods that capture culturally embedded expressions of distress, align them across languages, and link them with clinical terminology. Our approach addresses critical gaps in healthcare communication by grounding AI systems in culturally valid representations, allowing more inclusive and patient-centric NLP tools for mental health care in multilingual contexts.

Towards a Unified System of Representation for Continuity and Discontinuity in Natural Language

Ratna Kandala, Prakash Mondal

Syntactic discontinuity is a grammatical phenomenon in which a constituent is split into more than one part because of the insertion of an element which is not part of the constituent. This is observed in many languages across the world such as Turkish, Russian, Japanese, Warlpiri, Navajo, Hopi, Dyirbal, Yidiny etc. Different formalisms/frameworks in current linguistic theory approach the problem of discontinuous structures in different ways. Each framework/formalism has widely been viewed as an independent and non-converging system of analysis. In this paper, we propose a unified system of representation for both continuity and discontinuity in structures of natural languages by taking into account three formalisms, in particular, Phrase Structure Grammar (PSG) for its widely used notion of constituency, Dependency Grammar (DG) for its head-dependent relations, and Categorial Grammar (CG) for its focus on functor-argument relations. We attempt to show that discontinuous expressions as well as continuous structures can be analysed through a unified mathematical derivation incorporating the representations of linguistic structure in these three grammar formalisms.

Conjoined Predication and Scalar Implicature

Ratna Kandala

Magri (2016) investigates two puzzles arising from conjunction. Although Magri has proposed a solution to the second puzzle, the first remains unresolved. This first puzzle reveals a hidden interaction among quantification, collective/concurrent interpretation, and contextual updating dimensions that have yet to be explored. In essence, the problem is that certain forms of sentences like "Some Italians come from a warm country," when conjoined as in "(Only) Some Italians come from a warm country and are blond," sound infelicitous, even though no obvious alternative triggers a conflicting scalar implicature. In this paper, we offer a conceptual analysis of Magri's first puzzle by situating it within its original theoretical framework. We argue that the oddness arises from the collective or concurrent reading of the conjunctive predicate: in examples such as "(Only) Some Italians come from a warm country and are blond," this interpretation generates an indirect contextual contradiction. Moreover, we suggest that the pragmatic mechanisms governing scalar implicature generation extend beyond what is captured by exhaustification-based grammatical licensing accounts.
