Description

This set of scripts aims at learning various embeddings from online conversations to detect online abuse. Two main approaches are implemented: a content-based approach and a graph-based approach, which can also be used jointly. It leverages our library SWGE, which is described in [C'24, CDL'24], as well as methods from the literature, as described in the experimental protocol from [C'24, CDL'24]. The Alert repository implements similar functionalities, but using feature engineering instead of learned embeddings. This software is used in [CLDL'20a, C'24, CLD'24a] (cf. these publications for more details).

Data

This software was applied to a corpus of chat messages from the French MMORPG SpaceOrigin, already used for Alert, and presented in [PLDL'17, PLDL'17a, PLDL'17b, PLDL'18, PLDL'19, C'19, CLDL'19]. It also requires some signed graphs extracted from this textual corpus, which are available on Zenodo.

These conversational networks are also included as a zip file in this repository: unzip the SpaceOrigin_graphs.zip archive into the in/graphs folder. Conversation should be added in the in/text_conversations folder as a separate file for each conversation with each line corresponding to a message. An example is available on this repository.

Organization

Here are the folders composing the project:

  • Folder in: input data, including the textual conversations and graphs.
  • Folder SGCN: set of scripts to learn embeddings using the SGCN method [CLD'24a].
  • Folder signed_graph2vec: set of scripts to learn embeddings using the SG2V method [CLD'24a].
  • Folder emb: contains all the learned embeddings.
  • Folder output: output files generated by the methods, such as the weights.
  • Folder src: set of scripts to apply the standard unsigned graph embedding models and the text embedding methods.
  • main.py: main script used to launch all the experiments.

Installation

This library requires Python 3.8+. Dependencies car be installed with pip install -r requirements.txt

Use

The main script is the entry point to launch all the experiments. Use python main.py to run it.
