ASReview Makita

ASReviews' Makita (MAKe IT Automatic) is a workflow generator for simulation studies using the command line interface of ASReview LAB. Makita can be used to effortlessly generate the framework and code for your simulation study.

A simulation involves mimicking the screening process for a systematic review of a human in interaction with an Active learning model (i.e., a combination of a feature extractor, classifier, balancing method, and a query strategy). The simulation reenacts the screening process as if a researcher were using active learning. The performance of one or multiple model(s) can then be measured by performance metrics, such as the Work Saved over Sampling, recall at a given point in the screening process, or the average time to discover a relevant record.

Using Makita templates, different study structures can be generated to fit the needs of your very own study. If your study requires a unique template, you can create a new one and use it instead.

With ASReview LAB, you can simulate with the web interface, the Python API, or the Command Line Interface (CLI). Makita makes use of the CLI.

What Makita does:

• Setting up a workflow for running a large-scale simulation study
• Preparing a Github repository
• Automating the many lines of code needed
• Creating a batch script for running the simulation study with just one line of code
• Making your research fully reproducible
• Allowing you to add templates to accommodate your own specific research question

What Makita does not do:

• Executing jobs or tasks itself
• Being a black-box
• Writing your paper

For a tutorial on using Makita we refer to the Exercise on Using the ASReview Simulation Mode.

Installation

Install the Makita extension with pip:

pip install asreview-makita

For upgrading, use:

pip install --upgrade asreview-makita

After installing the extension, ASReview should automatically detect Makita. If installed correctly, asreview --help should list Makita as an option.

Getting started

You can create the framework and code for your own simulation study in 4 steps.

1. Create an project folder on your computer.
2. Create a subfolder named data and fill it using one or more datasets.
3. Using your preferred command line tool, cd into the project folder.
4. Create a simulation study from a template found in the list of templates via

asreview makita template NAME_OF_TEMPLATE

where NAME_OF_TEMPLATE is one of the templates (e.g. asreview makita template arfi).

Your simulation study is now properly set up and ready for use. To start the simulations, execute the following shell script in the project folder:

sh jobs.sh

The jobs.sh script is a shell script that runs all jobs in the project folder.

Platform support

By default, ASReview Makita renders job files for the platform of rendering. It is possible to render jobs for other platforms as well. Use the argument --platform with values "Windows", "Linux", or "Darwin" (MacOS) to change the output.

asreview makita template basic --platform Windows

By default, the job file depends on the platform. Windows users will see a jobs.bat file, while other users will see jobs.sh. You can overwrite this with

asreview makita template basic --job_file my_jobs_file.my_ext

Templates

The following table gives an overview of the available templates. See Getting started for instructions on usage.

Note: If no seed is set with the template command, the default seed is used. While this is important for the reproducibility of the results, it may lead to long-term bias. To avoid seed-related bias across different simulation studies, a seed should be for the prior records and models.

Basic template

command: basic

The basic template prepares a script for conducting a simulation study with one run using the default model settings, and two randomly chosen priors (one relevant and one irrelevant record).

optional arguments:

  -h, --help                                       show this help message and exit
  -f OUTPUT_FILE                                   File with jobs
  -s DATA_FOLDER                                   Dataset folder
  -o OUTPUT_FOLDER                                 Output folder
  --init_seed INIT_SEED                            Seed of the priors. Seed is set by default!
  --model_seed MODEL_SEED                          Seed of the models. Seed is set by default!
  --template TEMPLATE                              Overwrite template with template file path.
  --n_runs N_RUNS                                  Number of runs

ARFI template

command: arfi

The ARFI template (All relevant, fixed irrelevant) prepares a script for running a simulation study in such a way that for every relevant record 1 run will be executed with 10 randomly chosen irrelevant records which are kept constant over runs. When multiple datasets are available the template orders the tasks in the job file per dataset.

optional arguments:

  -h, --help                                       show this help message and exit
  -f OUTPUT_FILE                                   File with jobs
  -s DATA_FOLDER                                   Dataset folder
  -o OUTPUT_FOLDER                                 Output folder
  --init_seed INIT_SEED                            Seed of the priors. Seed is set by default!
  --model_seed MODEL_SEED                          Seed of the models. Seed is set by default!
  --template TEMPLATE                              Overwrite template with template file path.
  --n_priors N_PRIORS                              Number of priors

Multiple models template

command: multiple_models

The multiple model template prepares a script for running a simulation study comparing multiple models for one dataset and a fixed set of priors (one relevant and one irrelevant record; identical across models).

optional arguments:

  -h, --help                                       Show this help message and exit
  -f OUTPUT_FILE                                   File with jobs
  -s DATA_FOLDER                                   Dataset folder
  -o OUTPUT_FOLDER                                 Output folder
  --init_seed INIT_SEED                            Seed of the priors. Seed is set by default!
  --model_seed MODEL_SEED                          Seed of the models. Seed is set by default!
  --template TEMPLATE                              Overwrite template with template file path.
  --classifiers CLASSIFIERS [CLASSIFIERS ...]                           Classifiers to use
  --feature_extractors FEATURE_EXTRACTOR [FEATURE_EXTRACTORS ...]   Feature extractors to use
  --impossible_models IMPOSSIBLE_MODELS [IMPOSSIBLE_MODELS ...]         Model combinations to exclude

The default models are:

classifiers           ["logistic", "nb", "rf", "svm"]
feature_extractors   ["doc2vec", "sbert", "tfidf"]
impossible_models     [["nb", "doc2vec"], ["nb", "sbert"]]

Example command: If you want to generate a multiple models template with classifiers logistic and nb, and feature extraction tfidf, you can use the following command:

asreview makita template multiple_models --classifiers logistic nb --feature_extractors tfidf

If you want to specify certain combinations of classifiers and feature extractors that should not be used, you can use the --impossible_models option. For instance, if you want to exclude the combinations of nb with doc2vec and logistic with tfidf, use the following command:

asreview makita template multiple_models --classifiers logistic nb --feature_extractors tfidf doc2vec --impossible_models nb,doc2vec logistic,tfidf

Advanced usage

Create and use custom templates

It is possible to overwrite the internal templates. This can be useful for simulation studies with different needs.

1. Select an existing template that looks similar to your needs. For example, you want to run ARFI with a different model, then you pick the ARFI template.
2. Download the template you selected in step 1 from the Github repository. Template files have the following structure template_*.txt.template. For the ARFI example, the template is template_arfi.txt.template.
3. Save the downloaded template somewhere on your computer. The template is a so-called "Jinja" template. The template consists of ASReview command line commands combined with jinja syntax. The Jinja syntax is very intuitive. See this Cheatsheet.
4. Edit the Jinja template to your needs.
5. Run the custom template with the command line option --template PATH_TO_MY_TEMPLATE.txt.template. For the ARFI example, this would be asreview makita template arfi --template PATH_TO_MY_TEMPLATE.txt.template. Please keep in mind that you follow the usual steps for running a template.
6. A jobs.sh file should be in the your folder.

Please contribute your templates back to the project by making a Pull Request. Then, we can integrate it in the core of the makita package.

Add and use scripts

Makita can add scripts to your repository. The scripts are mainly pre- and postprocessing scripts. These scripts are not (yet) available in any existing ASReview software. Therefore, they can be added manually with asreview makita add-script NAME_OF_SCRIPT.

For example, the results from ASReview datatools are merged via the script merge_descriptives.py (or merge_metrics.py for ASReview insights), using:

1. Collect statistics (with template)
2. Run asreview makita add-script merge_descriptives.py
3. Run python scripts/merge_descriptives.py

Use -s (source) and -o (output) to tweak paths.

Some scripts are added automatically to the folder, as they are part of the template. For example, the get_plot.py script is added to the generated folder when using any template, as it is used to generate the plots.

Still, get_plot.py can be used on its own, as it is a standalone script. To use it, use -s (source) and -o (output) to tweak paths.

Adding a legend to the plot can be done with the -l or --show_legend flag, with the labels clustered on any of the following: 'filename', 'model', 'query_strategy', 'balance_strategy', 'feature_extraction', 'n_instances', 'stop_if', 'n_prior_included', 'n_prior_excluded', 'model_param', 'query_param', 'feature_param', 'balance_param'

Available scripts

The following scripts are available:

• get_plot.py
• get_settings_from_state.py
• merge_descriptives.py
• merge_metrics.py
• merge_tds.py
• split_data_with_multiple_labels.py [DEPRECATED]

Run Makita via Docker

To run Makita template with Docker use the following command:

docker run -v $PWD:/app ghcr.io/asreview/asreview makita <YOUR COMMAND>
