+# dwulff/mpnet-personality
+
+This is a [sentence-transformers](https://www.SBERT.net) model that maps personality-related items or texts into a 768-dimensional dense vector space and can be used for many tasks in personality psychology, such as clustering personality items and scales, mapping personality scales to personality constructs, and others.
+
+The model has been generated by fine-tuning [all-mpnet-base-v2](https://huggingface.co/sentence-transformers/all-mpnet-base-v2) using unsigned empirical correlations of 200k pairs of personality items. The model, therefore, encodes the content of personality-related texts independent of the direction (e.g., negation).  
+
+See [Wulff & Mata (2025)](https://doi.org/10.1038/s41562-024-02089-y) (see [Supplement](https://static-content.springer.com/esm/art%3A10.1038%2Fs41562-024-02089-y/MediaObjects/41562_2024_2089_MOESM1_ESM.pdf)) for details.
+
+## Usage
+
+Make sure [sentence-transformers](https://www.SBERT.net) is installed:
+
+```
+# latest version
+pip install -U sentence-transformers
+
+# latest dev version
+pip install git+https://github.com/UKPLab/sentence-transformers.git
+```
+
+You can extract embeddings in the following way:
+
+```python
+from sentence_transformers import SentenceTransformer
+
+# personality sentences
+sentences = ["Rarely think about how I feel.", "Make decisions quickly."]
+
+# load model
+model = SentenceTransformer('dwulff/mpnet-personality')
+
+# extract embeddings
+embeddings = model.encode(sentences)
+print(embeddings)
+```
+
+## Evaluation Results
+
+The model has been evaluated on public personality data. For standard personality inventories, such as the BIG5 or HEXACO inventories, the model predicts the empirical correlations between personality items at Pearson r ~ .6 and empirical correlations between scales at Pearson r ~ .7. 
+
+Performance can be higher on the many common personality items it has been trained on due to memorization (r ~ .9). Performance will be worse for more specialized personality assessments and texts beyond personality items, as well as for personality factors due to the reduced variance in correlations.
+
+See [Wulff & Mata (2025)](https://doi.org/10.1038/s41562-024-02089-y) (see [Supplement](https://static-content.springer.com/esm/art%3A10.1038%2Fs41562-024-02089-y/MediaObjects/41562_2024_2089_MOESM1_ESM.pdf)) for details.
