Pipeline Inspection, Visualization, and Interoperability in PyTerrier

2026-01-24

AI Summary

This work addresses the limited introspectability, visualizability, and interoperability with external tools in existing information retrieval (IR) pipelines, which hinder their interpretability and integration efficiency. To overcome these limitations, the paper introduces novel operations within the PyTerrier framework that enable structured introspection, interactive visualization, and interoperability via the Model Context Protocol (MCP). These capabilities facilitate transparent inspection and dynamic exploration of IR workflows, significantly enhancing pipeline transparency, debuggability, and cross-tool integration. The proposed approach provides researchers, students, and AI agents with more effective means to understand, analyze, and utilize IR systems.

Abstract

PyTerrier provides a declarative framework for building and experimenting with Information Retrieval (IR) pipelines. In this demonstration, we highlight several recent pipeline operations that improve their ability to be programmatically inspected, visualized, and integrated with other tools (via the Model Context Protocol, MCP). These capabilities aim to make it easier for researchers, students, and AI agents to understand and use a wide array of IR pipelines.
