Cross-media Structured Common Space for Multimedia Event Extraction
Table of Contents
Overview
The code for paper Cross-media Structured Common Space for Multimedia Event Extraction.
Requirements
You can install the environment using requirements.txt for each component.
pip install -r requirements.txt
Data
Situation Recognition (Visual Event Extraction Data)
We download situation recognition data from imSitu. Please find the preprocessed data in PreprcessedSR.
ACE (Text Event Extraction Data)
We preprcoessed ACE following JMEE. The preprocessing script is in dataflow/preprocess_ace_JMEE.py, and 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 showing your possession of the license for the processed data.
Voice of America Image-Caption Pairs
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). We preprocess the data including object detection, and parse text sentences. The preprocessed data is in PreprocessedVOA.
M2E2 (Multimedia Event Extraction Benchmark)
The images and text articles are in m2e2_rawdata, and annotations are in m2e2_annotation.
Vocabulary
Preprocessed vocabulary is in PreprocessedVocab.
Quickstart
Training
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.
Testing
(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.
