Harvesting Relational Tables from Lists on the Web

Summary: Unsupervised extraction of relational tables from web lists, handling delimiters and missing fields. Uses an HTML-table corpus to validate splits and alignments, yields an extraction score, and scales to ~100k lists, implying tens of millions of usable tables.
