# DFKI-MLST@DialAM-2024 Shared Task
[](https://aclanthology.org/2024.argmining-1.9) [](https://aclanthology.org/volumes/2024.argmining-1)

📌 Description

This repository contains the code for our submission to the DialAM-2024 Shared Task as described in the paper DFKI-MLST at DialAM-2024 Shared Task: System Description (Binder et al., ArgMining 2024) and poster presented at the ArgMining 2024 workshop co-located with ACL 2024 in Bangkok, Thailand. The task was part of the workshop and focused on the identification of argumentative relations in dialogues. See the official website for more information.

📃 Abstract

We present the dfki-mlst submission for the DialAM shared task on identification of argumentative and illocutionary relations in dialogue. Our model achieves the best results in the global setting: 48.25 F1 at the focused level when looking only at the related arguments/locutions and 67.05 F1 at the general level when evaluating the complete argument maps. We describe our implementation of the data pre-processing pipeline, relation encoding and classification, evaluating 11 different base models and performing experiments with, e.g., node text combination and data augmentation. Our source code is publicly available.

✨ How to Reproduce the Results from Our Paper

1. Set up the environment as described in the Environment Setup section.

2. Train models with the configuration from the paper (this will execute 3 runs with different seeds):

   python src/train.py \
   experiment=dialam2024_merged_relations \
   base_model_name=microsoft/deberta-v3-large \
   model.task_learning_rate=1e-4 \
   +model.classifier_dropout=0.1 \
   datamodule.batch_size=8 \
   trainer=gpu \
   seed=1,2,3 \
   +hydra.callbacks.save_job_return.integrate_multirun_result=true \
   --multirun

3. Run the inference on the test set (the model_save_dirs from the training step will be used as the model_name_or_path, see the content of the job_return_value.json in your logs/training folder for the exact paths):

   python src/predict.py \
   dataset=dialam2024_prepared \
   +dataset.input.name=merged_relations \
   model_name_or_path=MODEL/SAVE/DIR1,MODEL/SAVE/DIR2,MODEL/SAVE/DIR3 \
   +pipeline.device=0 \
   +pipeline.batch_size=8 \
   --multirun

   or run the inference with the model checkpoint from the paper (from Huggingface hub):

   python src/predict.py \
   dataset=dialam2024_prepared \
   +dataset.input.name=merged_relations \
   model_name_or_path=DFKI-SLT/dfki-mlst-deberta-v3 \
   +pipeline.device=0 \
   +pipeline.batch_size=8

4. Evaluate the results with the annotated shared task test data that are stored in data/evaluation_data. First, convert the serialized JSON documents into the JSON format required for the DialAM Shared Task with each nodeset in a separate JSON file (note that INPUT/DATA/DIR is the path to one of the directories where the predicted outputs from the previous step are stored):

   python src/utils/convert_documents2nodesets.py \
   --input_dir=INPUT/DATA/DIR \
   --output_dir=PREDICTION/DATA/DIR

   Second, evaluate using the official script for argumentative relations:

   python src/evaluation/eval_official.py \
   --gold_dir=data/evaluation_data \
   --predictions_dir=PREDICTION/DATA/DIR \
   --mode=arguments

   ... and for illocutionary relations:

   python src/evaluation/eval_official.py \
   --gold_dir=data/evaluation_data \
   --predictions_dir=PREDICTION/DATA/DIR \
   --mode=illocutions

   Depending on the hardware that is used to do the predictions the results may slightly vary, for H100 we achieved the following scores for argumentative relations:

   general.p: 0.61956118154322
   general.r: 0.5328788951094529
   general.f1: 0.5533113738298515
   focused.p: 0.43876262626262624
   focused.r: 0.2481962481962482
   focused.f1: 0.3039512181223411

   ... and for illocutionary relations:

   general.p: 0.8108195336938596
   general.r: 0.7925352836170968
   general.f1: 0.7878014615826178
   focused.p: 0.691260002623639
   focused.r: 0.6623577402989167
   focused.f1: 0.6610087288770674

🚀 Quickstart

Environment Setup

# clone project
git clone https://github.com/ArneBinder/dialam-2024-shared-task.git
cd dialam-2024-shared-task

# [OPTIONAL] create conda environment
conda create -n dialam-2024-shared-task python=3.9
conda activate dialam-2024-shared-task

# install PyTorch according to instructions
# https://pytorch.org/get-started/

# install remaining requirements
pip install -r requirements.txt

# [OPTIONAL] symlink log directories and the default model directory to
# "$HOME/experiments/dialam-2024-shared-task" since they can grow a lot
bash setup_symlinks.sh $HOME/experiments/dialam-2024-shared-task

# [OPTIONAL] set any environment variables by creating an .env file
# 1. copy the provided example file:
cp .env.example .env
# 2. edit the .env file for your needs!

Model Training

Have a look into the train.yaml config to see all available options.

Train model with default configuration

# train on CPU
python src/train.py

# train on GPU
python src/train.py trainer=gpu

Execute a fast development run (train for two steps)

python src/train.py +trainer.fast_dev_run=true

Train model with chosen experiment configuration from configs/experiment/

python src/train.py experiment=conll2003

You can override any parameter from command line like this

python train.py trainer.max_epochs=20 datamodule.batch_size=64

Start multiple runs at once (multirun):

python src/train.py seed=42,43 --multirun

Notes:

• this will execute two experiments (one after the other), one for each seed
• the results will be aggregated and stored in logs/multirun/, see the last logging output for the exact path

Model evaluation

This will evaluate the model on the test set of the chosen dataset using the metrics implemented within the model. See config/dataset/ for available datasets.

Have a look into the evaluate.yaml config to see all available options.

python src/evaluate.py dataset=conll2003 model_name_or_path=pie/example-ner-spanclf-conll03

Notes:

• add the command line parameter trainer=gpu to run on GPU

Inference

This will run inference on the given dataset and split. See config/dataset/ for available datasets. The result documents including the predicted annotations will be stored in the predictions/ directory (exact location will be printed to the console).

Have a look into the predict.yaml config to see all available options.

python src/predict.py dataset=conll2003 model_name_or_path=pie/example-ner-spanclf-conll03

Notes:

• add the command line parameter +pipeline.device=0 to run the inference on GPU 0

Evaluate Serialized Documents

This will evaluate serialized documents including predicted annotations (see Inference) using a document metric. See config/metric/ for available metrics.

Have a look into the evaluate_documents.yaml config to see all available options

python src/evaluate_documents.py metric=f1 metric.layer=entities +dataset.data_dir=PATH/TO/DIR/WITH/SPLITS

Note: By default, this utilizes the dataset provided by the from_serialized_documents configuration. This configuration is designed to facilitate the loading of serialized documents, as generated during the Inference step. It requires to set the parameter data_dir. If you want to use a different dataset, you can override the dataset parameter as usual with any existing dataset config, e.g dataset=conll2003. But calculating the F1 score on the bare conll2003 dataset does not make much sense, because it does not contain any predictions. However, it could be used with statistical metrics such as count_text_tokens or count_entity_labels.
