WiRe57 : A Fine-Grained Benchmark for Open Information Extraction

TL;DR

WiRe57 provides a detailed benchmark for open information extraction, including annotation guidelines and evaluation methods, to improve the assessment and development of IE systems.

Contribution

It introduces a fine-grained benchmark with standardized guidelines and evaluation scripts for open information extraction, addressing issues of inference and granularity.

Findings

MinIE outperforms other extractors

Benchmark enables precise system evaluation

Guidelines clarify extraction correctness

Abstract

We build a reference for the task of Open Information Extraction, on five documents. We tentatively resolve a number of issues that arise, including inference and granularity. We seek to better pinpoint the requirements for the task. We produce our annotation guidelines specifying what is correct to extract and what is not. In turn, we use this reference to score existing Open IE systems. We address the non-trivial problem of evaluating the extractions produced by systems against the reference tuples, and share our evaluation script. Among seven compared extractors, we find the MinIE system to perform best.
