Software Projects

Document Retrieval for Social Sciences Python Package “retfidf”

GitHub

Developed a Python tool for retrieving documents from large text corpora.

Technical Stack: Python, Word2Vec, TF-IDF

Questionnaire GAN for Online Survey Data Integrity

GitHub

Developed a GAN-based solution to simulate and detect fake responses in online surveys. Introduced a data-independent mechanism for fake response detection using overtrained discriminators.

Technical Stack: Python, Generative Adversarial Networks (GANs), Machine Learning.

Emotion Decomposition via Word Embeddings

GitHub

Extracted emotional dimensions from Reddit text using advanced word embeddings. Revealed patterns and clusters in emotional vectors through PCA visualizations.

Technical Stack: Python, NLP, PCA, Word Embeddings (Doc2Vec)

Affective Norms Extrapolation using Transformers

GitHub

Developed a state-of-the-art transformer-based neural network architecture for extrapolating semantic and emotional norms across multiple languages. Achieved superior correlations with human judgments, improving on prior models by Δr = 0.1 on average, and introduced a method for unsupervised control in stimuli selection. The project was accepted for publication in Behavior Research Methods.

Technical Stack: Python, Transformers, Machine Learning, Natural Language Processing.

Statcheck: Python Implementation for Statistical Checking

GitHub

Developed a Python implementation of the original R package statcheck by Michèle B. Nuijten, enhancing accessibility for the Python community. The tool automatically extracts NHST results from articles, recomputes p-values, and detects inconsistencies. Supports various statistical tests, including t-tests, F-tests, and z-tests, when reported in APA style. Main applications include manuscript self-checks, aiding peer review processes, and research, such as investigating predictors of statistical inconsistencies.

Technical Stack: Python, Text Processing, Statistical Analysis

Meta Yourself Tool (Shiny App)

Shiny App

Built an application for user-friendly exploratory bias detection in meta-analyses, which allows users to assess the reliability of scientific literature via keyword searches.

Technical Stack: R, Shiny, Meta-Analysis.
