Despite progress in variety classification, forensic linguistics often avoids these methods due to limited transparency. This work examines explainable machine learning for a geolinguistic profiling scenario using German-speaking social media data. It identifies the lexical items most influential for variety classification and finds them representative, while the trained models also exploit place names for categorization.","University of Birmingham  \nExplainability of machine learning approaches in forensic linguistics: a case study in geolinguistic authorship profiling  \nRoemling, Dana; Scherrer, Yves; Miletić, Aleksandra  \nDocument Version  \nPublisher's PDF, also known as Version of record  \nCitation for published version (Harvard):  \nRoemling, D , Scherrer, Y & Miletić, A 2024, Explainability of machine learning approaches in forensic linguistics: a case study in geolinguistic authorship profiling. in The first international conference on Natural Language Processing and Artificial Intelligence for Cyber Security, NLPAICS’2024: Proceedings.

This task is paralleled in dialect classiﬁcation, where a prediction is made about the linguistic variety of a text based on the text itself. While there have been signiﬁcant advances in recent years in variety classiﬁcation, forensic linguistics rarely relies on these approaches due to their lack of transparency, among other reasons. In this paper we therefore explore the explainability of machine learning approaches considering the forensic context. We focus on variety classiﬁcationas a means of geolinguistic proﬁling of unknown texts based on social media data from the German-speaking area. For this, we identify the lexical items that are the most impactful for the variety classiﬁcation. We ﬁnd that the extracted lexical features are indeed representative of their respective varieties and note that the trained models also rely on place names forclassiﬁcations.  \n1 Introduction
