Disentangling Political Bias in Social Media Data through Multi-task Embedding Learning (TCSS 2025)

A tensorflow implementation of DisMEL+TransE and data used in the paper [link].

jp-poli_rel_text.txt is the graph data represented as (head, relation, tail) triplets. tweet_text.txt contains tweet text and tweet id in the graph file.

Extracting Political Interest Model from Interaction Data Based on Novel Word-level Bias Assignment (TIST2025)

Code for BiDEL [link].

This package contains code and data for inferring word-level political bias from labeled texts. Please see readme.txt in the package for details.

Word-Level Political Sentiments Inferred from Social Media and Application in Recommendation Diversification (TWEB2024)

A Political Sentiment Dictionary for Japanese Language [html] [text].

This dictionary contains interest scores and political sentiment scores of 63,588 words, generated using the method presented in the paper. The TSV file contains three columns, for the word, interest score, and political sentiment score, respectively. A higher value indicates a leaning towards left, while a lower value indicates a leaning towards right.
