This is the personal assignment of zhiyuan hu on his Information Retrieval Class. The aim is to develop an IR system which can build index and conduct query effectively

Step1. Download dataset to the data directory

Please contact our teaching assistant since the dataset is not released.

Step2. Index construction

First, make sure you have started the Elasticsearch server, run the following command in the terminal

$ elasticsearch

Then construct the index.

python preprocess/index.py --docs <path_to_your_crops>

This process will be time-consuming, I am trying to accelerate it.

The program will print the document num of your crop, you need to manually fill this number to the 6ht line of frontend/util.py.

Step3. Start frontend and begin query!

python main.py

Access 127.0.0.1:5000 to begin your query.
