+# Model Card for `passage-ranker.mango`
+
+This model is a passage ranker developed by Sinequa. It produces a relevance score given a query-passage pair and is
+used to order search results.
+
+Model name: `passage-ranker.mango`
+
+## Supported Languages
+
+The model was trained and tested in the following languages:
+
+- Chinese
+- Dutch
+- English
+- French
+- German
+- Italian
+- Japanese
+- Portuguese
+- Spanish
+
+Besides the aforementioned languages, basic support can be expected for additional 93 languages that were used during
+the pretraining of the base model (see
+[list of languages](https://github.com/google-research/bert/blob/master/multilingual.md#list-of-languages)).
+
+## Scores
+
+| Metric              | Value |
+|:--------------------|------:|
+| Relevance (NDCG@10) | 0.480 |
+
+Note that the relevance score is computed as an average over 14 retrieval datasets (see
+[details below](#evaluation-metrics)).
+
+## Inference Times
+
+| GPU        | Batch size 32 |
+|:-----------|--------------:|
+| NVIDIA A10 |         84 ms |
+| NVIDIA T4  |        358 ms |
+
+The inference times only measure the time the model takes to process a single batch, it does not include pre- or
+post-processing steps like the tokenization.
+
+## Requirements
+
+- Minimal Sinequa version: 11.10.0
+- GPU memory usage: 1070 MiB
+
+Note that GPU memory usage only includes how much GPU memory the actual model consumes on an NVIDIA T4 GPU with a batch
+size of 32. It does not include the fix amount of memory that is consumed by the ONNX Runtime upon initialization which
+can be around 0.5 to 1 GiB depending on the used GPU.
+
+## Model Details
+
+### Overview
+
+- Number of parameters: 167 million
+- Base language model: [Multilingual BERT-Base](https://huggingface.co/bert-base-multilingual-uncased)
+- Insensitive to casing and accents
+- Training procedure: [MonoBERT](https://arxiv.org/abs/1901.04085)
+
+### Training Data
+
+- MS MARCO Passage Ranking
+  ([Paper](https://arxiv.org/abs/1611.09268),
+  [Official Page](https://microsoft.github.io/msmarco/),
+  [English & translated datasets on the HF dataset hub](https://huggingface.co/datasets/unicamp-dl/mmarco))
+    - Original English dataset
+    - Translated datasets for the other eight supported languages
+
+### Evaluation Metrics
+
+To determine the relevance score, we averaged the results that we obtained when evaluating on the datasets of the
+[BEIR benchmark](https://github.com/beir-cellar/beir). Note that all these datasets are in English.
+
+| Dataset           | NDCG@10 |
+|:------------------|--------:|
+| Average           |   0.480 |
+|                   |         |
+| Arguana           |   0.537 |
+| CLIMATE-FEVER     |   0.241 |
+| DBPedia Entity    |   0.371 |
+| FEVER             |   0.777 |
+| FiQA-2018         |   0.327 |
+| HotpotQA          |   0.696 |
+| MS MARCO          |   0.414 |
+| NFCorpus          |   0.332 |
+| NQ                |   0.484 |
+| Quora             |   0.768 |
+| SCIDOCS           |   0.143 |
+| SciFact           |   0.648 |
+| TREC-COVID        |   0.673 |
+| Webis-Touche-2020 |   0.310 |
+
+We evaluated the model on the datasets of the [MIRACL benchmark](https://github.com/project-miracl/miracl) to test its
+multilingual capacities. Note that not all training languages are part of the benchmark, so we only report the metrics
+for the existing languages.
+
+| Language | NDCG@10 |
+|:---------|--------:|
+| Chinese  |   0.463 |
+| French   |   0.447 |
+| German   |   0.415 |
+| Japanese |   0.526 |
+| Spanish  |   0.485 |
