Goal and organization of obelics

The folder obelics is aimed for:

• Download WARC files from Common Crawl dumps (warc_downloader.py);
• Extract HTML files from WARC files (html_extractor.py);
• Simplify HTML DOM trees (dom_tree_simplificator.py);
• Convert the simplified DOM trees to another structure adapted for an extraction (pre_extraction_simplificator.py);
• Perform an extraction (web_document_extractor.py);
• Perform a filtering on the extraction (web_document_filtering.py);
• Perform a line deduplication (web_document_line_deduplication.py);
• Visualize the results (visualization).

The primary techniques are defined in the sub-folder processors, while their invocation is found in callers. The configs used for the extraction and the filtering of the documents are in configs.

We refer to our paper for details about these steps.

In visualization, there are different streamlit visualizations:

• global_visualization.py to see original web pages and DOM trees, with our simplificated versions pre-filtering;
• choose_filtering_parameters_web_documents_node_level.py and web_document_and_filtering_visualization.py to see the impact of the filtering at node and document level, and help choosing the filter thresholds.
• web_document_visualization.py for a simple visualization of the final documents.

Goal and organization of build_obelics

In the folder build_obelics, we are giving all the scripts that were used for the creation of OBELICS, with numbers indicating the chronology.

These scripts often call methods defined in processors but not only, and also define other useful methods.
