## Setup Retrieve Sentences and end2end QA pipeline
|
|
|
|
#### 1. Assuming you've already followed the main [README](../README.md) instructions, just clone [Anserini](https://github.com/castorini/Anserini.git):
|
|
```bash
|
|
git clone https://github.com/castorini/Anserini.git
|
|
```
|
|
|
|
Your directory structure should look like
|
|
```
|
|
.
|
|
├── Anserini
|
|
├── Castor
|
|
├── Castor-data
|
|
└── models
|
|
```
|
|
|
|
#### 2. Compile Anserini
|
|
|
|
```bash
|
|
cd Anserini
|
|
mvn package
|
|
cd ..
|
|
```
|
|
|
|
This creates `anserini-0.0.1-SNAPSHOT.jar` at `Anserini/target`
|
|
|
|
We highly recommend the use of [virtualenv](https://virtualenv.pypa.io/en/stable/) as the dependencies
|
|
are subjected to frequent changes.
|
|
|
|
Install the dependency packages:
|
|
|
|
```
|
|
cd Castor
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
#### 3. Download Dependencies
|
|
- Download the TrecQA lucene index
|
|
- Download the Google word2vec file from [here](https://drive.google.com/drive/folders/0B2u_nClt6NbzNWJkWExmaklYNTA?usp=sharing)
|
|
|
|
### To run RetrieveSentences:
|
|
|
|
```bash
|
|
python ./anserini_dependency/RetrieveSentences.py
|
|
```
|
|
|
|
Possible parameters are:
|
|
|
|
| option | input format | default | description |
|
|
|----------------|--------------|---------|-------------|
|
|
| `-index` | string | N/A | Path of the Lucene index |
|
|
| `-embeddings` | string | "" | Path of the word2vec index |
|
|
| `-topics` | string | "" | topics file |
|
|
| `-query` | string | "" | a single query |
|
|
| `-hits` | [1, inf) | 100 | max number of hits to return |
|
|
| `-scorer` | string | Idf | passage scores (Idf or Wmd) |
|
|
| `-k` | [1, inf) | 1 | top-k passages to be retrieved |
|
|
|
|
Note: Either a query or a topic must be passed in as an argument; they can't be both empty.
|
|
|
|
|
|
__NB:__ The speech UI cannot be run in Ubuntu. To test the pipeline in Ubuntu, make the following changes:
|
|
- Comment out the JavaScript part and run the Bash script
|
|
- Make a REST API query to the endpoint using Postman, Curl etc.
|
|
|
|
### To setup the demo
|
|
|
|
#### 1. Installing libraries for demo
|
|
|
|
```sh
|
|
cd anserini_dependency/js
|
|
npm install
|
|
cd ../..
|
|
```
|
|
|
|
#### 2. Flask
|
|
|
|
- Flask is used as the server for the API
|
|
- Copy `config.cfg.example` to `config.cfg` and make necessary changes, such as setting the index path and API keys.
|
|
|
|
|
|
#### 3. Run the Demo
|
|
|
|
```sh
|
|
./run_ui.sh
|
|
```
|
|
|
|
### Additional Notes
|
|
- This is the documentation for the API call to send a question to the model and get back the predicted answer.
|
|
- The request body fields are: question(required )num_hits(optional) and k(optional).
|
|
```
|
|
|
|
# REQUEST:
|
|
HTTP Method: POST
|
|
Endpoint: [host]:[port]/answer
|
|
Content-Type: application/json
|
|
text of body in raw format:
|
|
{
|
|
"question": "What is the birthdate of Einstein?",
|
|
"num_hits": 50,
|
|
"k": 30
|
|
}
|
|
```
|
|
|
|
- The response body contains answers which is a list of objects with two fields - passage, score.
|
|
```
|
|
# RESPONSE:
|
|
Content-Type: application/json
|
|
text of body in raw format:
|
|
{
|
|
"answers": [
|
|
{"passage": "Einstein was born in the 1800s", 'score': 0.976},
|
|
{"passage": "Einstein was a physicist", 'score': 0.524}
|
|
]
|
|
}
|
|
```
