XQDT E2E verifier: qwen3 1.7B

This repository contains the LoRA adapter for the qwen3 1.7B XQDT verifier from XQDT: eXplainable and Quantitative Data-Text Alignment Metric with Feedback Signals. It is used with `Qwen/Qwen3-1.7B`.

This E2E checkpoint was trained on the joint WebNLG--E2E synthetic training set.

Overview

XQDT verifies alignment between English text and structured triples. It returns missing, extra, and incorrect units, or All correct. missing identifies an input unit omitted from the text, extra identifies text content unsupported by the input, and incorrect identifies an input unit realised with incorrect information.

Example inputs and outputs are provided in smoke_test.json. Generated text may vary slightly across inference libraries and package versions.

Prompt format

text

Verify if the triples align with the text. Find missing, extra, or incorrect triples.
TEXT: {text}
TRIPLES:
1. [S] {subject} [P] {predicate} [O] {object}
Output as markdown table with Type and Triple columns.
