Abstract
Graph neural networks have triggered a resurgence of graph-based text classification. We show that already a simple MLP baseline achieves comparable performance on benchmark datasets, questioning the importance of synthetic graph structures. When considering an inductive scenario, i. e., when adding new documents to a corpus, a simple MLP even outperforms most graph-based models. We further fine-tune DistilBERT for comparison and find that it outperforms all state-of-the-art models. We suggest that future studies use at least an MLP baseline to contextualize the results. We provide recommendations for the design and training of such a baseline.
