What's New in TREC 2017 DD Jig

• Python 3.5 environment
• Updates on CubeTest and new metrics: sDCG and Expected Utility
• Additional supporting file for evaluation

---

What's inside the package:

• the jig (jig/jig.py)
• evaluation metric scripts
• sample files

---

Requirements

1. System requirements

• Operation Systems: Mac OS, Windows, Linux.
• Python 3.5 environment.

2. Download the TREC DD Topics:

• Download the Topics (with ground truth) from NIST.

3. Obtain TREC DD Datasets:

• Obtain the TREC DD datasets following the instructions here.
• You will need to obtain the New York Times dataset from LDC.

Install the Jig

1. Download the jig package:

> git clone https://github.com/trec-dd/trec-dd-jig

2. Quick install Python packages needed:

> cd trec-dd-jig
> pip3 install -r requirements.txt

3. Setup the jig

• Create your own directory to hold your trec-dd search system.

  > mkdir your_dd_directory

• Put the jig package under your_dd_directory, that is,

  > mv trec-dd-jig your_dd_directory/.

• Unzip and put the topic (with ground truth) file that you downloaded from NIST, under ~/your_dd_directory/trec-dd-jig/jig/topics/

  > gunzip dd_topic_file.xml.gz
  > mv dd_topic_file.xml your_dd_directory/trec-dd-jig/topics/

• Uncompress and preprocess the datasets. In this jig package, we release sample files from both the Ebola and the NYT datasets. The following codes are for the NYT dataset. They can be run on both the sample files and the actual dataset. Remember to replace the input .tgz file with the actual dataset. The resulting corpus will be in TRECTEXT format.

  > cd trec-dd-jig
  > ./config/process_nyt.sh sample_doc/nyt_sample.tgz sample_doc/nyt_sample

  The first parameter is the .tgz file that you obtained from LDC, the second parameter is the output directory.

  The output directory will contain the following subdirectories:

  - nyt_corpus: a directory that contains the uncompressed New York Times dataset 
  - nyt_trectext: a directoty that contains the processed text in TRECTEXT format
  

• Setup database and prepare parameter files

  > python3 config/setup.py --topics sample_run/topic.xml --trecdirec sample_doc/ebola_sample sample_doc/nyt_sample/nyt_trectext --params sample_run/params

  • where:
    • topics: the topic xml file you download from NIST
    • trecdirec: the directory that holds the Ebola and New York Times dataset in TRECTEXT format
    • params: the parameter file needed in evaluation

  This script will set up a sqlite database at ./trec-dd-jig/jig/truth.db. It will also generate a parameter file which will be used later in the metric calculation. The parameter file for the sample is located at sample_run/params

  Remember to replace the file paths with the actual datasets.

  Congratulations to a successful installation of the jig!

Run the Jig

• Your systems should call python3 jig/jig.py to get feedback for each search iteration. The jig outputs a json dumped string. It provides feedback to your returned documents. Use the following command to call the Jig:

    > python3 jig/jig.py -runid my_runid -topic topic_id -docs docno1:rankingscore docno2:rankingscore docno3:rankingscore docno4:rankingscore docno5:rankingscore

  • where:

    • my_runid: An identifier used to declare the run
    • topic_id: the id of the topic you are working on
    • docno1, docno2 ...: the five document ids that your system returned. It needs to be the document ids in TREC DD datasets.
    • ranking score: the ranking score of the documents generated by your system

• Suppose your run id is 'testrun'. Call the jig with the topic id, the run id, the ids of the 5 documents that your system retrieved together with their ranking scores:

      > python3 jig/jig.py -runid testrun -topic DD16-1 -docs ebola-45b78e7ce50b94276a8d46cfe23e0abbcbed606a2841d1ac6e44e263eaf94a93:833.00 ebola-0000e6cdb20573a838a34023268fe9e2c883b6bcf7538ebf68decd41b95ae747:500.00 ebola-012d04f7dc6af9d1d712df833abc67cd1395c8fe53f3fcfa7082ac4e5614eac6:123.00 ebola-0002c69c8c89c82fea43da8322333d4f78d48367cc8d8672dd8a919e8359e150:34.00 ebola-9e501dddd03039fff5c2465896d39fd6913fd8476f23416373a88bc0f32e793c:5.00

• The jig will print the feedback on the screen. Each feedback is a json dumped string.

• A run file will be automatically generated at the current directory with the runid as its name. This will be the run file that you submit to NIST later.

• Everytime when you run jig/jig.py for the same topic id, the run file will be automatically appended and the number of iterations will increase by one.

Metrics

• In 2017, the Track mainly uses three metrics: Cube Test, Session DCG (sDCG) and Expected Utility. We will provide both the raw scores and the normalized scores for each of them. We also include Precision as an additional metric. The scripts for these metrics can be found at the ./scorer directory.

• You will need the actual topic xml file from NIST and the parameter file generated during installation to evaluate your runs. Remember to replace the sample files in the syntax.

• The following input arguments are shared by the scoring scripts

  • runfile: the run file generated by the jig
  • topics: the ground truth file that is downloaded from NIST
  • params: the parameter file generated during installation
  • cutoff: the number of iterations to be evaluated, eg. --cutoff 5 means the scores are calulated based on the first 5 iterations.

• To run the scorers:

  • Cube Test

    Syntax

      >$ python3 scorer/cubetest.py --runfile your_runfile --topics your_topic.xml --params your_params_file --cutoff your_cut_off_value

    To run the example

      >$ python3 scorer/cubetest.py --runfile testrun.txt --topics sample_run/topic.xml --params sample_run/params --cutoff 5

  • Session DCG (sDCG)

    Syntax

      >$ python3 scorer/sDCG.py --runfile your_runfile --topics your_topic.xml --params your_params_file --cutoff your_cut_off_value

    To run the example

      >$ python3 scorer/sDCG.py --runfile testrun.txt --topics sample_run/topic.xml --params sample_run/params --cutoff 5

  • Expected Utility

    Syntax

      >$ python3 scorer/expected_utility.py --runfile your_runfile --topics your_topic.xml --params your_params_file --cutoff your_cut_off_value

    To run the example

      >$ python3 scorer/expected_utility.py --runfile testrun.txt --topics sample_run/topic.xml --params sample_run/params --cutoff 5

  • Precision (up to the current iteration)

    Syntax

      >$ python3 scorer/precision.py -run your_run_file -qrel your_qrel_file

    To run the example

      >$ python3 scorer/precision.py -run testrun.txt -qrel sample_run/qrels.txt
