Quick Start

Running on raw text data

• Prepare a data directory data containing sub-directories rsd and ltf. The rsd sub-directory contains RSD (Raw Source Data, ending with *.rsd.txt), and ltf sub-directory has LTF (Logical Text Format, ending with *.ltf.xml) files.
  • If you have RSD files, please use the aida_utilities/rsd2ltf.py to generate the LTF files.

  docker run --rm -v ${ltf_dir}:${ltf_dir} -v ${rsd_dir}:${rsd_dir} -i limanling/uiuc_ie_m36 /opt/conda/envs/py36/bin/python /aida_utilities/rsd2ltf.py --seg_option nltk+linebreak --tok_option nltk_wordpunct --extension .rsd.txt ${rsd_dir} ${ltf_dir}

  • If you have LTF files, please use the AIDA ltf2rsd tool (LDC2018E62_AIDA_Month_9_Pilot_Eval_Corpus_V1.0/tools/ltf2txt/ltf2rsd.perl) to generate the RSD files.
• Start services

sh set_up_m36.sh

• Run the scripts. Note that the file paths are absolute paths.

sh pipeline_full_en.sh ${data_root} ${GPU_id}

For example,

sh pipeline_full_en.sh ${PWD}/data/testdata_dryrun 0

If there is no gpu, please only set the data_root parameter:

sh pipeline_full_en.sh ${data_root}

AIDA M36: Running LDC corpus and link entities to LDC released KB

sh pipeline_sample_m36.sh ${data_root_ldc} ${kb_data_dir} ${output_dir} ${parent_child_tab} ${en_asr_path} ${en_ocr_path} ${ru_ocr_path} ${thread_num}

where parent_child_tab is the file meta data in docs of LDC corpus. kb_data_dir is the data directory of a LDC released KB, such as ${PWD}/data/LDC2020E27_AIDA_Phase_2_Practice_Topics_Reference_Knowledge_Base_V1.1/data. For example,

sh pipeline_sample_m36.sh ${PWD}/data/LDC2020E29 ${PWD}/data/LDC2020E27_AIDA_Phase_2_Practice_Topics_Reference_Knowledge_Base_V1.1/data ${PWD}/output/output_dryrun_E29_test ${PWD}/data/LDC2020E11_AIDA_Phase_2_Practice_Topic_Source_Data_V1.0/docs/parent_children.tab ${PWD}/output/output_dryrun_E11_asr_aln ${PWD}/data/video.ocr/en.cleaned.csv ${PWD}/data/video.ocr/ru.cleaned.csv 20

If there is no ASR and OCR files, please use None as input, e.g.,

sh pipeline_sample_m36.sh ${PWD}/data/LDC2020E29 ${PWD}/data/LDC2020E27_AIDA_Phase_2_Practice_Topics_Reference_Knowledge_Base_V1.1/data ${PWD}/output/output_dryrun_E29_test ${PWD}/data/LDC2020E11_AIDA_Phase_2_Practice_Topic_Source_Data_V1.0/docs/parent_children.tab None None None 20

Run on reduced version

Reduced Version disables the functions that will take long runningtime, including the functions of entity filler extraction (time, value, title, etc), part of fine-grained event extraction, etc.

sh pipeline_reduced.sh ${data_root_ltf} ${data_root_rsd} ${output_dir}

For example,

sh pipeline_reduced.sh ${PWD}/data/testdata_dryrun/ltf ${PWD}/data/testdata_dryrun/rsd ${PWD}/output/output_reduced_dryrun

Run on multimedia data

Step 1. Data preparation

Please prepare the input data file structure:

- CU_toolbox
- data 
  |------rsd
  |------ltf
  |------vision
  |------------data/jpg/jpg
  |------------data/video_shot_boundaries/representative_frames
  |------------docs/video_data.msb
  |------------docs/masterShotBoundary.msb
  |------------docs/parent_children.tab
  |------cu_objdet_results
  |------cu_grounding_results
  |------cu_grounding_matching_features
  |------cu_grounding_dict_files

where docs/video_data.msb and docs/masterShotBoundary.msb are empty files and data/video_shot_boundaries/representative_frames is an empty directory. docs/parent_children.tab contains meta data of images and text documents in the format of catalog_id version parent_uid child_uid url child_asset_type topic lang_id lang_manual rel_pos wrapped_md5 unwrapped_md5 download_date content_date status_in_corpus, separated by TAB. If one image (e.g., image_1.jpg) and one text document (e.g., text_1.ltf.xml) belongs to the same news article (e.g., doc_1), then it should be formatted as:

gaia v1 doc_1 image_1 0 .jpg 0 0 0 0 0 0 0 0 0
gaia v1 doc_1 text_1 0 .ltf.xml 0 0 0 0 0 0 0 0 0

Please avoid . in the file names and use JPG as image suffix.

The sample code of preparation is in uiuc_ie_pipeline_fine_grained/multimedia/sample_data_preparation.py.

Please find the sample data and result in sample_data. The CU_toolbox can be downloaded in CU_toolbox.

Step 2. Object detection and cross-media coreference

Please run uiuc_ie_pipeline_fine_grained/multimedia/multimedia.sh to extract objects from images, and perform cross-media coreference. The object results are saved in cu_objdet_results/aida_output_34.pkl(pickle format), and grounding results are saved in cu_grounding_results(pickle format) and cu_graph_merging_ttl (RDF format). Please find the grounding result visualization code in uiuc_ie_pipeline_fine_grained/multimedia/visualize_ttl_grounding.py using the RDF format output.
