# A resolved representation of the CeLLaTe Dataset
## Overview
This dataset represents an un-edited, whole version of CeLLaTe.
There are no splits, and no entity tags outside of those from the base dataset schema:
- **CellType**
- **CellLine**
- **Tissue**
This version of CeLLaTe allows for a view which is not manipulated or obscured by any downstream tasks carried out in efforts to train transformer models.
### On 'vague' terms
Two versions of this dataset have been created: one retaining _'vague'_ entities and one excluding them (this dataset).
_'Vague'_ terms were removed through the use of a vague terms dictionary, seen at: _https://github.com/EuropePMC/OTAR3088/blob/main/docs/vague_entity_examples.tsv_
The filtering of _'vague'_ entities applies exclusively to the subsects of CeLLaTe which were manually curated.
These are the splits which contain articles of 'single-cell transcriptomics' and 'pharmacology' themes.
We define vague entities as terms that do not strictly satisfy the criteria of a well-defined
named entity, but may exhibit entity-like characteristics depending on contextual usage.
## Dataset Schema
Columns are as follows:
- sentence: a single sentence extracted from a biomedical article
- entities: a list of entity annotations associated with the sentence
- data_source: the originating corpus or article collection from which the sentence was derived
Annotations are provided at the sentence level to facilitate downstream NER training, evaluation, and AL-driven re-annotation workflows
## Data Sources and Domain Composition
The dataset integrates articles from three complementary biomedical domains, each contributing distinct entity distributions:
### 1. Single cell transcriptomics Literature:
- High prevalence of CellType and Tissue entities
- Rich terminology diversity
- Manually curated
### 2. Pharmacology literature
- Enriched in CellLine mentions
- MedChem articles were retrieved here from the ChEMBL 34 database
- SQLite queries linked the ASSAY DESCRIPTIONS and DOCS tables, collecting supporting literature for assay descriptions mentioning cell lines
- Manually curated
### 3. Stem Cell Research (CellFinder)
- Contains all three entity types
- Particularly rich in CellType mentions
- Historically curated dataset with expert annotations (Dated more than 10 years ago)
This multi-domain composition allows the evaluation of:
- Cross-domain robustness
- Entity distribution shifts
- Label imbalance behaviour
- Domain adaptation strategies

## Stem Cell Article Source (CellFinder)
Stem cell–related articles were obtained from the CellFinder repository.The original dataset and annotation methodology are described in:
>Mariana Neves, Alexander Damaschun, Andreas Kurtz, Ulf Leser (2012)
>Annotating and evaluating text for stem cell research.
>In Proceedings Third Workshop on Building and Evaluation Resources for Biomedical Text Mining (BioTxtM 2012),
>Language Resources and Evaluation (LREC) 2012.
The CellFinder corpus provides historically curated annotations across multiple stem-cell–related entity types.
