Hierarchical text classification has many real-world applications. However, labeling a large number of documents is costly. In practice, we can use semi-supervised learning or weakly supervised learning (e.g., dataless classification) to reduce the labeling cost. In this paper, we propose a path cost-sensitive learning algorithm to utilize the structural information and further make use of unlabeled and weakly-labeled data. We use a generative model to leverage the large amount of unlabeled…

TaxoClass: Hierarchical Multi-Label Text Classification Using Only Class Names
This paper proposes a novel HMTC framework, named TaxoClass, which calculates document-class similarities using a textual entailment model, identifies a document’s core classes and utilizes confident core classes to train a taxonomy-enhanced classifier, and generalizes the classifier via multi-label self-training.
HiGitClass: Keyword-Driven Hierarchical Classification of GitHub Repositories
The HiGitClass framework is proposed, comprising of three modules: heterogeneous information network embedding; keyword enrichment; topic modeling and pseudo document generation, which is superior to existing weakly-supervised and dataless hierarchical classification methods, especially in its ability to integrate both structured and unstructured data for repository classification.
Forget me not: A Gentle Reminder to Mind the Simple Multi-Layer Perceptron Baseline for Text Classification
It is shown that already a simple MLP baseline achieves comparable performance on benchmark datasets, questioning the importance of synthetic graph structures and providing recommendations for the design and training of such a baseline.
Minimally Supervised Categorization of Text with Metadata
MetaCat is proposed, a minimally supervised framework to categorize text with metadata that develops a generative process describing the relationships between words, documents, labels, and metadata and embeds text and metadata into the same semantic space to encode heterogeneous signals.
