Queries from Web Tables Quantity queries, with filter conditions on quantitative measures of entities, are so far out of reach of search engines and QA assistants. To enable such queries over web contents [...] Answering Quantity Queries from Web Tables (Demo paper) Vinh Thinh Ho, Koninika Pal, and Gerhard Weikum In Proc.

This involves recognizing quantities, with normalized values and units, aligning them with the
text sources, and a novel matching model to retrieve and rank answers from news articles and other web pages.
