As more papers get included in Digital collections satisfying information needs is becoming harder. In particular, when the user searches for information beyond bibliographic metadata. The situation is even worse when the information need requires a key aspect of a paper that first needs to be annotated for indexing purposes and thus, allow searching. For instance, in the biomedical field this might apply to structured abstracts, e.g. ‘background’, ‘objectives’, ‘results’, ‘methods’ and ‘conclusion’. Current state-of-the-art deep learning approaches can only succeed if a sufficiently large amount of annotated data is available for training purposes. However, annotating several thousands of documents is not only expensive, but due to the limited availability of experts often even infeasible. To alleviate this problem, we explore the use of Language Inference as a universal feature that once applied to a limited number of annotated documents can help to achieve high accuracy to generate the desired metadata. We show through our experiments the degree of success on the difficult task of generating the structured metadata of biomedical papers and its performance stability as we increase the number of examples. We compare our suggested approach with deep learning approaches such as Doc2Vec and show that language inference is up to two orders of magnitude better achieving up to 0.82 F1 scores
