Features

TaxoNERD is a domain-specific tool for recognizing taxon mentions in the biodiversity literature.

:tada: New models are out ! Now including additional NLP components (tagger, attribut ruler, lemmatizer, parser) and more accurate common names detection.

• TaxoNERD is available as a command-line tool, a Python module, a spaCy pipeline, and a R package thanks to reticulate.
• TaxoNERD provides two architectures : the md architecture uses spaCy's standard Tok2Vec layer with word vectors for speed, while the biobert architecture uses a Transformer-based pretrained language model (dmis-lab/biobert-v1.1) for accuracy.
• TaxoNERD finds scientific names, common names, abbreviated species names and user-defined abbreviations.
• TaxoNERD can link taxon mentions to entities in a reference taxonomy (NCBI Taxonomy, GBIF Backbone and TAXREF at the moment, more to come).
• TaxoNERD is fast (once the model is loaded), and can run on CPU or GPU.
• Entity linking does not need an internet connection, but may require a lot of RAM depending on the size of the taxonomy (e.g. GBIF Backbone -> ~12.5Gb).
• Thanks to textract, TaxoNERD can extract taxon mentions from (almost) any document (including txt, pdf, csv, xls, jpg, png, and many other formats). With TaxoNERD, the detection of taxonomic entities in a JPG file is as simple as that:

taxonerd ask -m en_core_eco_weak_biobert -f ./tests/test_data/test_jpg/test.jpg 
T0	LIVB 180 192	Harbour seal
T1	LIVB 194 208	Phoca vitulina
T2	LIVB 361 375	Pacific salmon
T3	LIVB 377 394	Oncorhynchus spp.
T4	LIVB 455 467	harbour seal
T5	LIVB 714 718	seal
T6	LIVB 793 805	harbour seal
T7	LIVB 1127 1133	fishes
T8	LIVB 1137 1148	cephalopods

Models

What model should I choose ?

If you have access to a GPU, we recommend using one of the biobert models as they tend to be more accurate than the md models.

The en_core_eco_weak_md and en_core_eco_weak_biobert have been fine-tuned on a silver standard corpus generated using weak supervision. Therefore, they have been trained on a much larger amount of (noisy) data than their gold standard counterparts. As a result, they tend to have better recall, especially with respect to common names detection. They also have high precision. Nevertheless, their performance has not been accurately evaluated.

If you do not trust weakly-supervised data and you are not really interested in detecting common names, en_core_eco_md and en_core_eco_biobert are for you. These models have been fine-tuned on a gold standard corpus (a combination of COPIOUS and Bacteria Biotope 2019) and their performance has been benchmarked in our paper.

Installation

TaxoNERD for Python

Installing the package from pip will automatically install all dependencies, including pandas, spaCy, scispaCy and textract. Make sure you install this package before you install the models. Also note that this package requires Python 3.8+ and spaCy v3.4+.

$ pip install taxonerd

For GPU support, find your CUDA version using nvcc --version and add the version in brackets, e.g. pip install taxonerd[cuda113] for CUDA 11.3. See setup.cfg for supported CUDA versions.

To download the models:

$ pip install https://github.com/nleguillarme/taxonerd/releases/download/v1.5.0/en_core_eco_md-1.0.2.tar.gz
$ pip install https://github.com/nleguillarme/taxonerd/releases/download/v1.5.0/en_core_eco_biobert-1.0.2.tar.gz
$ pip install https://github.com/nleguillarme/taxonerd/releases/download/v1.5.0/en_core_eco_weak_md-1.0.0.tar.gz
$ pip install https://github.com/nleguillarme/taxonerd/releases/download/v1.5.0/en_core_eco_weak_biobert-1.0.0.tar.gz

Entity linker files are downloaded and cached the first time the linker is used. This may take some time, but it should only be done once. Currently (v1.5.1), there are 3 supported linkers:

• gbif_backbone: Links to GBIF Backbone Taxonomy (2019-09-06) (~9.5M names for ~3.5M taxa).
• taxref: Links to TAXREF (v13) (~1.2M names for ~267k taxa).
• ncbi_taxonomy: Links to The NCBI Taxonomy (~3.4M names).

Use as python module

>>> from taxonerd import TaxoNERD
>>> taxonerd = TaxoNERD(prefer_gpu=False)
>>> nlp = taxonerd.load(model="en_core_eco_md", exclude=[], linker="taxref", threshold=0.7)
>>> nlp.pipe_names
['tok2vec', 'tagger', 'attribute_ruler', 'lemmatizer', 'pysbd_sentencizer', 'parser', 'ner', 'taxo_abbrev_detector', 'taxref_linker']

N.B. By default, all components are included in the pipeline. Use the exclude argument to specify the components to exclude. Excluded components won’t be loaded. This may speed up the detection process. The minimal pipeline for taxonomic NER is ['tok2vec', 'ner'].
