Project developed for the MIRVC course of the Master of Artificial Intelligence and Data Engineering at the University of Pisa.

This project consists in the design and implementation of a Search Engine for MSMARCO dataset. Checkout the assignment and the report for all the information about the project.

To run this project you need to download in the main folder the MSMARCO dataset.

1. Import the project in Visual Studio/Visual Studio Code

2. Build the project using Cmake

3. Execute app.exe

1. Install the required software

$ sudo apt-get install git cmake build-essential zlib1g-dev libboost-all-dev

2. Download the source code

$ git clone --recursive https://github.com/edoardoruffoli/MSMARCO-Search-Engine

3. Generate the build files

$ cd MSMARCO-Search-Engine
$ mkdir build && cd build
$ cmake ..

4. Build

$ make

5. Run

$ cd bin
$ ./app

*** Started MSMARCO Search Engine ***
Available commands:
  help - display a list of commands
  query - perform a query
  eval - execute a queries dataset, saving the result file for trec_eval
  index - create the inverted index
  exit - exit the program

Enter a command:
>query
Enter the query execution mode:
    0 : CONJUNCTIVE_MODE
    1 : DISJUNCTIVE_MODE
    2 : DISJUNCTIVE_MODE_MAX_SCORE
