BIOMAT-MONER: A Domain-Specific Corpus for Named Entity Recognition of Manufactured Objects Relevant to Biomaterials Research

BIOMAT-MONER Corpus BIOMAT-MONER stands for BIOMATerials Manufactured Object Named Entity Recognition. It is a corpus developed within the scope of the Horizon Europe BIOMATDB project to support the extraction and classification of manufactured object relevant to biomaterials research entity mentions from scientific literature in the biomaterials domain. The corpus focuses on the annotation of manufactured objects, including references to devices, tools, experimental apparatus, and implantable medical products, along with their chemical, physical, and mechanical properties among other relevant features, as well as their trade names, that are described in the context of their use in biomaterials-related experiments or applications. 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) terms associated with biomaterials, medical devices, and related fields. The abstracts were then manually annotated according to the rules predefined in the annotation guidelines. The BIOMAT-MONER corpus is one of four developed within the BIOMATDB project and is divided into three subsets: a training set (750 documents), a test set (150 documents), and a validation set (100 documents). It is available in multiple formats, including brat, CSV, and CoNLL, to support diverse NLP workflows. 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 manufactured object mentions relevant to biomaterials research.
