Trie data structure speeds up IR pipeline experiments by 26%

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel method using a trie data structure to optimize the evaluation of complex information retrieval (IR) pipelines. This approach, detailed in a new paper, aims to reduce the computational cost associated with comparing different pipeline configurations. Empirical tests on the MSMARCO v2 dataset, utilizing retrievers like BM25, MonoT5, and DuoT5, demonstrated a 26% decrease in experiment duration. The study also includes findings from a user study involving research students. AI

IMPACT This research could lead to more efficient development and testing of complex AI-powered search and recommendation systems.

    Trie-based Experiment Plans for Efficient IR Pipeline Experiments

    Search engines are often formulated as cascading pipelines, where successive stages combine the results of different retrievers, and iteratively refine the ranking of candidate documents to obtain a final ranking, which can be presented to a user, or provided as context to an LLM…
