q-MAP: sensitive QA systems with mapped question embeddings

privJedAI: A Unified Open-Source Pipeline for Privacy-Preserving Record Linkage

Privacy-Preserving Record Linkage (PPRL) is a crucial task for interlinking different, but overlapping data sources without compromising their privacy. PPRL has evolved from simple hash-based exact matching methods to more sophisticated ones in the last two decades. However, existing open-source PPRL systems have limit...

PYTHIA: Universal Question Answering over Knowledge Graphs

PYTHIA is presented, a training-free, plug-and-play solution for KGQA over any RDF KG which consists of an LLM agent guided by a relation-centric conceptual model of the KGQA task which is acted upon through a suite of tools for entity linking, graph exploration and query execution.

AgenticER: the next frontier in Entity Resolution

This work formalizes Agentic ER as a decision-theoretic problem, proposes a reference architecture, identifies core research challenges, and outlines new evaluation dimensions tailored to agentic behavior.

PYTHIA: Universal Question Answering over Knowledge Graphs

Knowledge graph question answering (KGQA) focuses on answering questions with data retrieved from knowledge graphs (KGs). Although Large Language Models (LLMs) have enabled the development of innovative KGQA systems, serious challenges remain. Approaches that utilize supervised finetuning are accurate and responsive, b...
