Scientific Table Search Using Keyword Queries

Understand

Tables are common and important in scientific documents, yet most text-based document search systems do not capture structures and semantics specific to tables.

• How to bridge different types of mismatch between keywords queries and scientific tables and what influences ranking quality needs to be carefully investigated.
• This paper considers the structure of tables and gives different emphasis to table components.
• On the query side, thanks to external knowledge such as knowledge bases and ontologies, key concepts are extracted and used to build structured queries, and target quantity types are identified and used to expand original queries.
