BIOMAT-CellNER: A Biomaterials Domain-Specific Corpus for Named Entity Recognition of Cell Mentions

BIOMAT-CellNER Corpus BIOMAT-CellNER stands for BIOMATerials Cell Named Entity Recognition. It is a corpus developed within the scope of the Horizon Europe BIOMATDB project to support the extraction and classification of cell entity mentions from the scientific literature in the biomaterials domain. It focuses on the annotation of cell mentions, including both cell types (e.g., fibroblasts, stem cells) and cell lines (e.g., HeLa, MC3T3), particularly those that are studied in interaction with biomaterials in experimental settings. The corpus was created through a collaborative effort involving domain experts, who were tasked with the establishment of comprehensive and accurate annotation guidelines for the manual annotation of the final gold standard corpus. To ensure domain relevance and terminological coverage, PubMed abstracts were carefully selected based on relevant MeSH (Medical Subject Headings) categories associated with biomaterials, tissue engineering, and related fields. The abstracts were then manually annotated according to the predefined rules in the annotation guidelines. The BIOMAT-CellNER corpus is one of four developed within the project and is divided into three subsets: a training set (750 documents), a test set (150 documents), and a validation set (100 documents), available in multiple formats, including brat, CSV and CoNLL. This corpus is part of a broader initiative to support the development of an advanced, searchable biomaterials database with integrated analytical tools and digital advisors. It is also intended for use in training Named Entity Recognition (NER) models, enabling the automatic identification and extraction of cell mentions relevant to biomaterials research.
