Large-Scale Semantic Indexing of Biomedical Publications
Automated annotation of scientific publications in real-world digital libraries requires dealing with challenges such as large number of concepts and training examples, multi-label training examples and hierarchical structure of concepts. BioASQ is a European project that contributes a large-scale biomedical publications corpus for working on these challenges. This paper documents the participa...
متن کاملLarge-scale Semantic Indexing with Biomedical Ontologies
We introduce PubTator, a web-based application that enables large-scale semantic indexing and automatic concept recognition in biomedical ontologies. Not only was PubTator formally evaluated and top-rated in BioCreative, it also has been widely adopted and used by the scientific community from around the world, supporting both research projects and real-world applications in biocuration, crowds...
متن کاملSupplementary Material: Hierarchical Semantic Indexing for Large Scale Image Retrieval
Remark 1.1. We first provide proofs and constructions for probability vectors for non-overlapping categories (Lemma 1.4– 1.12), i.e. x ∈ R , ∑ i xi = 1, 0 ≤ xi ≤ 1 for i = 1, . . . ,K. We use ∆K−1 to denote the set of all such vectors. In Lemma 1.15, we show extension to the general case where x ∈ R , 0 ≤ xi ≤ 1 for i = 1, . . . ,K (but does not necessarily sum to one). We use ∆̃K−1 to denote th...
متن کاملDeepMeSH: deep semantic representation for improving large-scale MeSH indexing
MOTIVATION Medical Subject Headings (MeSH) indexing, which is to assign a set of MeSH main headings to citations, is crucial for many important tasks in biomedical text mining and information retrieval. Large-scale MeSH indexing has two challenging aspects: the citation side and MeSH side. For the citation side, all existing methods, including Medical Text Indexer (MTI) by National Library of M...
متن کاملConceptual Indexing: Practical Large-Scale AI for Efficient Information Access
Finding information is a problem shared by people and intelligent systems. This paper describes an experiment combining both human and machine aspects in a knowledgebased system to help people find information in text. Unlike many previous attempts, this system demonstrates a substantial improvement in search effectiveness by using linguistic and world knowledge and exploiting sophisticated kno...
