This paper presents recent advances toward an integrated framework that combines TEI-based digital publishing with embedding-based semantic search to support the preservation, exploration and analysis of Holocaust survivor testimonies. The corpus includes written and oral sources and preserves them within a XML-TEI model supported by an ODD customization that preserves provenance, structure and interpretability. A dedicated web application developed within the eXistdb platform provides guided access to the digital corpus and supports the management, visualization, and exploration of the encoded data. The project aims to investigate a specific research goal: to verify the presence of references to the Divine Comedy by Dante within Holocaust testimonies. To this end, we implement a semantic retrieval component based on SentenceTransformers’ embeddings and a vector database, enabling the discovery of both literal and non-literal Dantean passages within the testimonies. The paper presents the advances achieved toward this objective and the ethical constraints shaping access policies, resulting in a sustainable archive and a reproducible methodology for intertextual research in sensitive historical collections.

In Nazi concentration camps, approximately 20 million people perished. This included young and old, men and women, Jews, dissidents, and homosexuals. Only 10% of those deported survived. This paper introduces “Voci dall’Inferno” project, which aims to achieve two key objectives: a) Create a comprehensive digital archive: by encoding a corpus of non-literary testimonies including both written and oral sources. b) Analyze the use of Dante’s language: by identifying the presence of Dante’s lexicon and allusions. Currently, the project holds 47 testimonies, with 29 transcribed in full text and 18 encoded using the XML-TEI format. This project is propelled by a multidisciplinary and educational context with experts in humanities and computer science. The project’s findings will be disseminated through a user-friendly web application built on an XML foundation. Though currently in its prototyping phase, the application boasts several features, including a search engine for testimonies, terms, or phrases within the corpus. Additionally, a browsing interface allows users to read and listen the original testimonies, while a visualization tool enables deeper exploration of the corpus’s content. Adhering to the Text Encoding Initiative (TEI) guidelines, the project ensures a structured digital archive, aligned with the FAIR principles for data accessibility and reusability.
