Relation Extraction Datasets in the Digital Humanities Domain and their Evaluation with Word Embeddings
This work addresses the need for domain-specific evaluation datasets in digital humanities, but it is incremental as it applies existing methods to new data.
The researchers tackled the problem of evaluating word embedding models for relation extraction in the digital humanities by manually creating datasets from fantasy novels and testing models like word2vec and GloVe on small corpora, finding that factors like corpus term frequencies and task difficulty affect accuracy.
In this research, we manually create high-quality datasets in the digital humanities domain for the evaluation of language models, specifically word embedding models. The first step comprises the creation of unigram and n-gram datasets for two fantasy novel book series for two task types each, analogy and doesn't-match. This is followed by the training of models on the two book series with various popular word embedding model types such as word2vec, GloVe, fastText, or LexVec. Finally, we evaluate the suitability of word embedding models for such specific relation extraction tasks in a situation of comparably small corpus sizes. In the evaluations, we also investigate and analyze particular aspects such as the impact of corpus term frequencies and task difficulty on accuracy. The datasets, and the underlying system and word embedding models are available on github and can be easily extended with new datasets and tasks, be used to reproduce the presented results, or be transferred to other domains.
