"""Descriptions of genetic variations and their effect are widely spread across the biomedical literature. However, finding all mentions of a specific variation, or all mentions of variations in a specific gene, is difficult to achieve due to the many ways such variations are described. Here, we describe SETH, a tool for the recognition of variations from text and their subsequent normalization to dbSNP or UniProt. SETH achieves high precision and recall on several evaluation corpora of PubMed abstracts. It is freely available and encompasses stand-alone scripts for isolated application and evaluation as well as a thorough documentation for integration into other applications. The script loads dataset in bigbio schema (using knowledgebase schema: schemas/kb) AND/OR source (default) schema """ from pathlib import Path from typing import Dict, List, Tuple import datasets from .bigbiohub import kb_features from .bigbiohub import BigBioConfig from .bigbiohub import Tasks _LANGUAGES = ['English'] _PUBMED = True _LOCAL = False _CITATION = """\ @Article{SETH2016, Title = {SETH detects and normalizes genetic variants in text.}, Author = {Thomas, Philippe and Rockt{"{a}}schel, Tim and Hakenberg, J{"{o}}rg and Lichtblau, Yvonne and Leser, Ulf}, Journal = {Bioinformatics}, Year = {2016}, Month = {Jun}, Doi = {10.1093/bioinformatics/btw234}, Language = {eng}, Medline-pst = {aheadofprint}, Pmid = {27256315}, Url = {http://dx.doi.org/10.1093/bioinformatics/btw234 } """ _DATASETNAME = "seth_corpus" _DISPLAYNAME = "SETH Corpus" _DESCRIPTION = ( """SNP named entity recognition corpus consisting of 630 PubMed citations.""" ) _HOMEPAGE = "https://github.com/rockt/SETH" _LICENSE = 'Apache License 2.0' _URLS = { "source": "https://github.com/rockt/SETH/archive/refs/heads/master.zip", "bigbio_kb": "https://github.com/rockt/SETH/archive/refs/heads/master.zip", } _SUPPORTED_TASKS = [Tasks.NAMED_ENTITY_RECOGNITION, Tasks.RELATION_EXTRACTION] _SOURCE_VERSION = "1.0.0" _BIGBIO_VERSION = "1.0.0" class SethCorpusDataset(datasets.GeneratorBasedBuilder): """SNP named entity recognition corpus consisting of 630 PubMed citations."""
