Benefits of technology
The invention provides methods for collecting and evaluating large amounts of data to identify relevant data facets that can be used to classify and narrow search queries. This involves reviewing structured and semi-structured data and query logs, using probabilities to select good facets, and determining optimal ranges and groupings of the facets. White and black lists can be used to avoid certain fields. The result is a dynamically determined dataset that improves the user experience by categorizing data and facilitating search queries.
Problems solved by technology
Attempts to provide general classifications (early implementations of search engines such as Yahoo!, for example) often become outdated, overly burdensome or, even worse, irrelevant.
While facet-based searching provides a significant improvement over conventional query / result methods, it is not without its drawbacks.
In particular, current techniques for implementing faceted-based search require a significant amount of work to determine the facets long before a website is implemented.
Likewise, it is difficult to change the facets as the underlying data and queries evolve without disrupting or modifying the functionality of the search application that acts on the data.

Embodiment Construction
[0019]Consumer websites often facilitate product searching using data facets. Conventional methods of implementing data-faceted search require manual analysis and selection of the data facets based on known, fielded properties that exist in the data. Referring to FIG. 1, for example, a web page 100 a collection of laptop computers available at a retail store and organized by five data facets 110. Specifically, the available laptops are grouped according to processor type, screen size, proposed use, price and manufacturer, such that visitors to the webpage can narrow their searches for a particular product meeting certain criteria. Furthermore, each data facet includes not only values (e.g., groupings) 120 for each facet 110, but the number of items 130 that meet that particular criteria. Visitors select a grouping 120 based on individual preferences, and the selection is sent to an underlying search engine which applies the values as filter criteria in a subsequent query that return...

Documents and data are analyzed to determine one or more data facets. The documents, data and other information contained therein may be presented according to statistically-determined groupings based on the data facets.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 353,565 filed Jan. 14, 2009, which claims priority to and the benefits of U.S. provisional patent application Ser. No. 61 / 022,001, entitled “Dynamic Determination Of Data Facets” and filed Jan. 18, 2008, the entire disclosure of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention relates generally to techniques for data search and retrieval, and more specifically, to the determination of parameters for classification, organization, presentation and retrieval of data.BACKGROUND[0003]Data presented to consumers of electronic information is often provided in pure “list” form—that is, as a one-dimensional listing in response to a query. Although much effort goes into determining the contents of the list, the ordering of the results and even the visual presentation of individual items, the consumer must still have some knowledge of the sub...
