US Patent 10163144 Extracting data from a catalog

Techniques for extracting unstructured quantitative data may be provided. For example, a process may attempt to extract unstructured quantitative data to form structured data. This quantitative data may be used for searchable ordering of items in an electronic marketplace. For example, a process may attempt to find common attributes amongst several item descriptions. The common attributes may be recognized in the unstructured data, stored as structured data, and incorporated with a network page to allow the user to search for a particular item with a particular attribute. The desired attribute can help narrow a set of results from a search query.
