DeepMeSH: 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 کاملLarge-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 کاملMeSHLabeler: improving the accuracy of large-scale MeSH indexing by integrating diverse evidence
MOTIVATION Medical Subject Headings (MeSHs) are used by National Library of Medicine (NLM) to index almost all citations in MEDLINE, which greatly facilitates the applications of biomedical information retrieval and text mining. To reduce the time and financial cost of manual annotation, NLM has developed a software package, Medical Text Indexer (MTI), for assisting MeSH annotation, which uses ...
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...
