JDK8 and Apache Lucene 6.2.1 is required for running the code.

To run machine learning algorithms there is another repository in python with Tensorflow

All of data(including test collection, goldens, etc) and libraries are ignored in git repository.

These files can be downloaded from dropbox This file includes three folders, data_java, data_php and lib

The lib folder includes all libraries(including Apache Lucene and jsoup) required to run the project

The data_java and data_php folders include the following files and folders (The names are based on java directory, but they are same for php dataset too):

• golden: The golden collection described in the paper.
• java_a_tag.txt: Tags for each answer (Answers don't have tag by their self, taged are extracted from related questions)
• java_q_tag.txt: Tags for each question.
• java_Q_A.txt: each question and it's answer ids.
• Posts.xml: This file is removed from data(due to it's very large size), This is the main dataset obtained from archive.org including posts from 2008-07-31 until 2015-03-08 at the time we download it. the version used in our paper can be downloaded here

Codes include a simple GUI to be used more easily.

Add data folder to the project and put Posts.xml inside it. Then Index posts using the button. All other functions have their own button.

Please cite the paper, If you used the codes in this repository.
