Knowledge Graph-Enhanced Zero-Shot Topic Classification: A Multi-Strategy Comparative Study

arXiv:2605.30465v1 Announce Type: new Abstract: Multi-label topic classification without labeled training data is a challenging task, specially when documents contain complex relational information. We present a zero-shot multi-label topic classification framework and systematically investigate how per-article knowledge graph augmentation affects its performance. The base framework classifies topics in documents without labeled training data and has four variants: article-only classification, keyword-enhanced classification, and self-consistency decoding variants of both. Then, we augment each

Why this matters
Why now

The proliferation of unlabeled data and the increasing complexity of information necessitate advanced methods for efficient topic classification without extensive human annotation.

Why it’s important

This research provides a more efficient and robust method for categorizing large volumes of information, which is critical for knowledge management, search, and autonomous AI systems operating in complex information environments.

What changes

The ability to accurately classify topics in document streams without requiring labeled training data and with enhanced performance via knowledge graphs significantly improves the scalability and adaptability of information processing systems.
