1. Please clone this repo to your local machine.

2. Download Wikipedia's database from here.

3. Import this database into your MySQL Server.

4. Edit DiscrMetaPath/src/main/java/edu/nd/dsg/util/ConnectionPool.java, change URL, USER, and PASS to yours.

5. Unzip DiscrMetaPath/data.tar.gz to DiscrMetaPath/, after this you should have all the data under DiscrMetaPath/data

6. Build the project by make wikibuild. The jar file will be generated under DiscrMetaPath/target/

7. Run generated jar file by java -jar JAR_FILE_YOU_GENERATED

The command line arguments are:

    Usage
    Generate paths: -GEN [-NoSQL cache types first to speedup] [-all get all paths instead of pathLength == 2] [-p build patent]
    Translate paths: -TRANS [-a output all paths] [-nd do not get most discri/similar paths] [-oNum get NUM paths between discri&similar paths] [-p build patent]
    Generate Term frequency: -TERM [-BuildWikiTF generate term frequency] [-BuildPatentTF generate term frequency] [-BuildWikiDF generate document frequency] [-BuildPatentDF generate document frequency]
    Generate Cos distance frequency(sequential): -COS [-p build patent]
    Generate BM25 score: -BM [-ACC accumulative (x,y),(x+y,z),...] [-NODE  sequential (x,y),(y,z),...] [-p build patent]

If you only interested in the results we get, you can get the data from result folder. The data format for each file is:

• For CrowdFlower result files:

    _unit_id,
    _golden,
    _canary,
    _unit_state,
    _trusted_judgments,
    _last_judgment_at,
    choose_path,    // Path that chosen by human
    choose_path:confidence,
    end,    // End article
    path_1, // Path between start and end, generated by our algorithm
    path_2,
    path_3,
    path_4,
    path_5,
    start   // Start article
  

• For other csv files:

    groupId, // Each unique groupId represent for a CrowdFlower task
    pathId, //  Equivalent to CrowFlower's path_*
    nodeId, //  Score of the node at position `i` in path_*
