The code for paper Cross-media Structured Common Space for Multimedia Event Extraction.

You can install the environment using requirements.txt for each component.

pip install -r requirements.txt

We download situation recognition data from imSitu. Please find the preprocessed data in PreprcessedSR.

We preprcoessed ACE following JMEE. The sample data format is in sample.json. Due to license reason, the ACE 2005 dataset is only accessible to those with LDC2006T06 license, please drop me an email manling2@illinois.edu showing your possession of the license for the processed data.

We crawled VOA image-captions to train the common space, the image-caption pairs and images can be downloaded using the URLs (We share image URLs instead of downloaded images due to license issue) using script in dataset_image_download.py. We preprocess the data including object detection, and parse text sentences. The preprocessed data is in PreprocessedVOA.

The images and text articles are in m2e2_rawdata, and annotations are in m2e2_annotation under data directory.

Preprocessed vocabulary is in PreprocessedVocab.

We have two variants to parse images into situation graph, one is parsing images to role-driven attention graph, and another is parsing images to object graphs.

(1) attention-graph based version

sh scripts/train/train_joint_att.sh 

(2) object-graph based version:

sh scripts/train/train_joint_obj.sh 

Please specify the data paths datadir, glovedir in scripts.

(1) attention-graph based version

sh test_joint.sh

(2) object-graph based version:

sh test_joint_object.sh

Please specify the data paths datadir, glovedir, and model paths checkpoint_sr, checkpoint_sr_params, checkpoint_ee, checkpoint_ee_params in scripts.
