- query: What is a corporation? |
|
passage: A company is incorporated in a specific nation, often within the bounds |
|
of a smaller subset of that nation, such as a state or province. The corporation |
|
is then governed by the laws of incorporation in that state. A corporation may |
|
issue stock, either private or public, or may be classified as a non-stock corporation. |
|
If stock is issued, the corporation will usually be governed by its shareholders, |
|
either directly or indirectly. |

# Passage Reranking Multilingual BERT 🔃 🌍 |
|
|
|
|
|
|
|
## Model description |
|
**Input:** Supports over 100 Languages. See [List of supported languages](https://github.com/google-research/bert/blob/master/multilingual.md#list-of-languages) for all available. |
|
|
|
**Purpose:** This module takes a search query [1] and a passage [2] and calculates if the passage matches the query. |
|
It can be used as an improvement for Elasticsearch Results and boosts the relevancy by up to 100%. |
|
|
|
**Architecture:** On top of BERT there is a Densly Connected NN which takes the 768 Dimensional [CLS] Token as input and provides the output ([Arxiv](https://arxiv.org/abs/1901.04085)). |
|
|
|
**Output:** Just a single value between between -10 and 10. Better matching query,passage pairs tend to have a higher a score. |
|
|
|
|
|
|
|
## Intended uses & limitations |
|
Both query[1] and passage[2] have to fit in 512 Tokens. |
|
As you normally want to rerank the first dozens of search results keep in mind the inference time of approximately 300 ms/query. |
|
|
|
#### How to use |
|
|
|
```python |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification |
|
|
|
tokenizer = AutoTokenizer.from_pretrained("amberoad/bert-multilingual-passage-reranking-msmarco") |
|
|
|
model = AutoModelForSequenceClassification.from_pretrained("amberoad/bert-multilingual-passage-reranking-msmarco") |
|
``` |
|
|
|
This Model can be used as a drop-in replacement in the [Nboost Library](https://github.com/koursaros-ai/nboost) |
|
Through this you can directly improve your Elasticsearch Results without any coding. |
|
|
|
|
|
## Training data |
|
|
|
This model is trained using the [**Microsoft MS Marco Dataset**](https://microsoft.github.io/msmarco/ "Microsoft MS Marco"). This training dataset contains approximately 400M tuples of a query, relevant and non-relevant passages. All datasets used for training and evaluating are listed in this [table](https://github.com/microsoft/MSMARCO-Passage-Ranking#data-information-and-formating). The used dataset for training is called *Train Triples Large*, while the evaluation was made on *Top 1000 Dev*. There are 6,900 queries in total in the development dataset, where each query is mapped to top 1,000 passage retrieved using BM25 from MS MARCO corpus. |
|
|
|
## Training procedure |
|
|
|
The training is performed the same way as stated in this [README](https://github.com/nyu-dl/dl4marco-bert "NYU Github"). See their excellent Paper on [Arxiv](https://arxiv.org/abs/1901.04085). |
|
|
|
We changed the BERT Model from an English only to the default BERT Multilingual uncased Model from [Google](https://huggingface.co/bert-base-multilingual-uncased). |
|
|
|
Training was done 400 000 Steps. This equaled 12 hours an a TPU V3-8. |
|
|
|
|
|
## Eval results |
|
|
|
We see nearly similar performance than the English only Model in the English [Bing Queries Dataset](http://www.msmarco.org/). Although the training data is English only internal Tests on private data showed a far higher accurancy in German than all other available models. |
