Overview

This data was used to evaluate the two models below to decide whether convergence was reached. https://huggingface.co/PDBEurope/BiomedNLP-PubMedBERT-ProteinStructure-NER-v2.1 https://huggingface.co/PDBEurope/BiomedNLP-PubMedBERT-ProteinStructure-NER-v3.1

There are 20 different entity types in this dataset: "bond_interaction", "chemical", "complex_assembly", "evidence", "experimental_method", "gene", "mutant", "oligomeric_state", "protein", "protein_state", "protein_type", "ptm", "residue_name", "residue_name_number","residue_number", "residue_range", "site", "species", "structure_element", "taxonomy_domain"

Annotation was carried out with the free annotation tool TeamTat (https://www.teamtat.org/) and documents were downloaded as BioC XML before converting them to IOB, annotation only JSON and CSV format.

The number of annotations and sentences in each file is given below:

document ID number of annotations in BioC XML number of annotations in IOB/JSON/CSV number of sentences
PMC5173035 885 885 195
PMC4993997 1052 1051 217
PMC5014086 676 676 136
PMC5063996 1048 1046 243

PMC4806292 760 760 167
PMC5603727 1353 1353 240
total 10113 10109 2101

Documents and annotations are easiest viewed by using the BioC XML files and opening them in free annotation tool TeamTat (https://www.teamtat.org/). More about the BioC format can be found here: https://bioc.sourceforge.net/

Raw BioC XML files

These are the raw, un-annotated XML files for the publications in the dataset in BioC format. The files are found in the directory: "raw_BioC_XML" There is one file for each document and they follow standard naming "unique PubMedCentral ID"_raw.xml

Annotations in IOB format

The IOB formated files can be found in the directory: "annotation_IOB". There is one file for each document in the dataset and they all follow the naming "unique PubMedCentral ID".tsv.

Annotations in BioC JSON

The BioC formated JSON files of the publications have been downloaded from the annotation tool TeamTat. The files are found in the directory: "annotated_BioC_JSON" There is one file for each document and they follow standard naming "unique PubMedCentral ID"_ann.json

Each document JSON contains the following relevant keys:

  • "sourceid" --> giving the numerical part of the unique PubMedCentral ID
  • "text" --> containing the complete raw text of the publication as a string
  • "denotations" --> containing a list of all the annotations for the text

Each annotation is a dictionary with the following keys:

  • "span" --> gives the start and end of the annotatiom span defined by sub keys:
    • "begin" --> character start position of annotation
    • "end" --> character end position of annotation
  • "obj" --> a string containing a number of terms that can be separated by ","; the order of the terms gives the following: entity type, reference to ontology, annotator, time stamp
  • "id" --> unique annotation ID

Here an example:

[{"sourceid":"4784909",
  "sourcedb":"",
  "project":"",
  "target":"",
  "text":"",
  "denotations":[{"span":{"begin":24,
                          "end":34},
                  "obj":"chemical,CHEBI:,melaniev@ebi.ac.uk,2023-03-21T15:19:42Z",
                  "id":"4500"},
                 {"span":{"begin":50,
                          "end":59},
                  "obj":"taxonomy_domain,DUMMY:,melaniev@ebi.ac.uk,2023-03-21T15:15:03Z",
                  "id":"1281"}]
  }
]

Annotations in BioC XML

The BioC formated XML files of the publications have been downloaded from the annotation tool TeamTat. The files are found in the directory: "annotated_BioC_XML" There is one file for each document and they follow standard naming "unique PubMedCentral ID_ann.xml

The key XML tags to be able to visualise the annotations in TeamTat as well as extracting them to create the training data are "passage" and "offset". The "passage" tag encloses a text passage or paragraph to which the annotations are linked. "Offset" gives the passage/ paragraph offset and allows to determine the character starting and ending postions of the annotations. The tag "text" encloses the raw text of the passage.

Each annotation in the XML file is tagged as below:

  • "annotation id=" --> giving the unique ID of the annotation
  • "infon key="type"" --> giving the entity type of the annotation
  • "infon key="identifier"" --> giving a reference to an ontology for the annotation
  • "infon key="annotator"" --> giving the annotator
  • "infon key="updated_at"" --> providing a time stamp for annotation creation/update
  • "location" --> start and end character positions for the annotated text span
    • "offset" --> start character position as defined by offset value
    • "length" --> length of the annotation span; sum of "offset" and "length" creates the end character position

Here is a basic example of what the BioC XML looks like. Additional tags for document management are not given. Please refer to the documenttation to find out more.

        <text>Coenzyme A</text>
      </annotation>
    </passage>
  </document>
</collection>

Annotations in CSV

The annotations and the relevant sentences they have been found in have also been made available as tab-separated CSV files, one for each publication in the dataset. The files can be found in directory "annotation_CSV". Each file is named as "unique PubMedCentral ID".csv.

The column labels in the CSV files are as follows:

  • "anno_start" --> character start position of the annotation
  • "anno_end" --> character end position of the annotation
  • "anno_text" --> text covered by the annotation
  • "entity_type" --> entity type of the annotation
  • "sentence" --> sentence text in which the annotation was found
  • "section" --> publication section in which the annotation was found

Annotations in JSON

A combined JSON file was created only containing the relevant sentences and associated annotations for each publication in the dataset. The file can be found in directory "annotation_JSON" under the name "annotations.json".

The following keys are used:

  • "PMC4850273" --> unique PubMedCentral of the publication
  • "annotations" --> list of dictionaries for the relevant, annotated sentences of the document; each dictionary has the following sub keys
    • "sid" --> unique sentence ID
    • "sent" --> sentence text as string
    • "section" --> publication section the sentence is in
    • "ner" --> nested list of annotations; each sublist contains the following items: start character position, end character position, annotation text, entity type

Here is an example of a sentence and its annotations:

{"PMC4850273": {"annotations":
                [{"sid": 0,
                  "sent": "Molecular Dissection of Xyloglucan Recognition in a Prominent Human Gut Symbiont",
                  "section": "TITLE",
                  "ner": [
                    [24,34,"Xyloglucan","chemical"],
                    [62,67,"Human","species"],]
                 },]
}}
