Latest Patents

One of his latest patents is titled "Data search queries for descriptive semantics extracted from item reviews." This invention discloses various embodiments for performing data search queries that utilize descriptive semantics derived from customer reviews. The process involves identifying search queries that lead to a selection of a browse node within an item taxonomy. It also determines various items associated with that browse node. The customer reviews are analyzed to extract phrases that appear in both the reviews and the search queries. These phrases are then ranked based on a polarity metric that assesses their subjectivity, sentiment, and coverage. Phrases that exceed a predefined rank threshold are made available for use by a search component of a network site.

Another significant patent is "Extracting product facets from unstructured data." This platform assesses queries related to catalog entries by determining the attributes the query targets using language processing techniques. Once an attribute is identified, the platform checks for appropriate unit types and formats based on the associated category. It then parses additional data related to the catalog entry to identify potential values for the identified attribute. Rule sets may be employed to filter these values down to a single probable value, which is then provided in response to the query.
