FMAT

😷 The Fill-Mask Association Test (掩码填空联系测验).

The Fill-Mask Association Test (FMAT) is an integrative and probability-based method using BERT Models to measure conceptual associations (e.g., attitudes, biases, stereotypes, social norms, cultural values) as propositions in natural language (Bao, 2024, JPSP).

⚠️ Please update this package to version ≥ 2024.6 for faster and more robust functionality.

Installation

To use the FMAT, the R package FMAT and three Python packages (transformers, torch, huggingface-hub) all need to be installed.

(1) R Package

## Method 1: Install from CRAN
install.packages("FMAT")

## Method 2: Install from GitHub
install.packages("devtools")
devtools::install_github("psychbruce/FMAT", force=TRUE)

(2) Python Environment and Packages

Install Anaconda (a recommended package manager which automatically installs Python, Python IDEs like Spyder, and a large list of necessary Python package dependencies).

Specify the Anaconda’s Python interpreter in RStudio.

RStudio → Tools → Global/Project Options
→ Python → Select → Conda Environments
→ Choose “…/Anaconda3/python.exe”

Install specific versions of Python packages “transformers”, “torch”, and “huggingface-hub”.
(RStudio Terminal / Anaconda Prompt / Windows Command)

For CPU users:

pip install transformers==4.40.2 torch==2.2.1 huggingface-hub==0.20.3

For GPU (CUDA) users:

pip install transformers==4.40.2 huggingface-hub==0.20.3
pip install torch==2.2.1 --index-url https://download.pytorch.org/whl/cu121

See Guidance for GPU Acceleration for installation guidance if you have an NVIDIA GPU device on your PC and want to use GPU to accelerate the pipeline.
According to the May 2024 releases, “transformers” ≥ 4.41 depends on “huggingface-hub” ≥ 0.23. The suggested versions of “transformers” (4.40.2) and “huggingface-hub” (0.20.3) ensure the console display of progress bars when downloading BERT models while keeping these packages as new as possible.
Proxy users should use the “global mode” (全局模式) to download models.
If you see the error HTTPSConnectionPool(host='huggingface.co', port=443), please try to (1) reinstall Anaconda so that some unknown issues may be fixed or (2) downgrade the “urllib3” package to version ≤ 1.25.11 (pip install urllib3==1.25.11) so that it will use HTTP proxies (rather than HTTPS proxies as in later versions) to connect to Hugging Face.

Guidance for FMAT

Step 1: Download BERT Models

Use BERT_download() to download BERT models. Model files are saved to your local folder “%USERPROFILE%/.cache/huggingface”. A full list of BERT models are available at Hugging Face.

Use BERT_info() and BERT_vocab() to find detailed information of BERT models.

Step 2: Design FMAT Queries

Design queries that conceptually represent the constructs you would measure (see Bao, 2024, JPSP for how to design queries).

Use FMAT_query() and/or FMAT_query_bind() to prepare a data.table of queries.

Step 3: Run FMAT

Use FMAT_run() to get raw data (probability estimates) for further analysis.

Several steps of preprocessing have been included in the function for easier use (see FMAT_run() for details).

For BERT variants using <mask> rather than [MASK] as the mask token, the input query will be automatically modified so that users can always use [MASK] in query design.
For some BERT variants, special prefix characters such as \u0120 and \u2581 will be automatically added to match the whole words (rather than subwords) for [MASK].

Notes

Improvements are ongoing, especially for adaptation to more diverse (less popular) BERT models.
If you find bugs or have problems using the functions, please report them at GitHub Issues or send me an email.

Guidance for GPU Acceleration

By default, the FMAT package uses CPU to enable the functionality for all users. But for advanced users who want to accelerate the pipeline with GPU, the FMAT_run() function now supports using a GPU device, about 3x faster than CPU.

Test results (on the developer’s computer, depending on BERT model size):

CPU (Intel 13th-Gen i7-1355U): 500~1000 queries/min
GPU (NVIDIA GeForce RTX 2050): 1500~3000 queries/min

Checklist:

Ensure that you have an NVIDIA GPU device (e.g., GeForce RTX Series) and an NVIDIA GPU driver installed on your system.
Install PyTorch (Python torch package) with CUDA support.
- Find guidance for installation command at https://pytorch.org/get-started/locally/.
- CUDA is available only on Windows and Linux, but not on MacOS.
- If you have installed a version of torch without CUDA support, please first uninstall it (command: pip uninstall torch) and then install the suggested one.
- You may also install the corresponding version of CUDA Toolkit (e.g., for the torch version supporting CUDA 12.1, the same version of CUDA Toolkit 12.1 may also be installed).

Example code for installing PyTorch with CUDA support:
(RStudio Terminal / Anaconda Prompt / Windows Command)

pip install torch==2.2.1 --index-url https://download.pytorch.org/whl/cu121

BERT Models

The reliability and validity of the following 12 representative BERT models have been established in my research articles, but future work is needed to examine the performance of other models.

While the FMAT is an innovative method for the computational intelligent analysis of psychology and society, you may also seek for an integrative toolbox for other text-analytic methods. Another R package I developed—PsychWordVec—is useful and user-friendly for word embedding analysis (e.g., the Word Embedding Association Test, WEAT). Please refer to its documentation and feel free to use it.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
