To Run the Program

1. Go inside the project's folder from terminal;
2. Execute chmod a+x ./run.sh to give permission to the shell script;
3. Run run.sh by command ./run.sh;
4. The script will check for the environment and install necessary libraries. Manual installation might be asked for, including but not limited to,
       Python 3
       numpy
       nltk.all-corpora.
   If the script fails to install them, please install them manually. nltk_download.py is provided for nltk_data;
5. After seeing "ALL-FINISHED" from terminal, results can be checked from results_file.txt;
6. eval_results.txt is the result I got from trec_eval. It includes non-interpolated average precision and precisions when 10 and 30 documents were retrieved.
