Methods and Apparatus for Entity Search

Abstract

Methods and apparatus that deliver a searching experience that is substantially akin to consultation with a human expert, and that satisfies a user's information need in fulfilling projects such as purchasing, shopping, procurement, bartering, requesting for quotes, in online retail, traditional retail, wholesale, health care, travel, real estate, restaurant-going, entertainment, logistics, and sourcing are disclosed. Search results often contain entities that provide services and products. Records being searched are associated with industry sectors in a broad sense. Industry sector information is first derived from a user query; and is used in determining relevant and adequate additional questions for a searcher, and in matching, ranking, and presenting search results.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional application of previously filed U.S. patent application having Ser. No. 11 / 751,802 filed on May 22, 2007; which claims priority to U.S. provisional application Ser. No. 60 / 811,989 filed Jun. 7, 2006.FIELD OF THE INVENTION[0002]The field of the invention is searching technologies.BACKGROUND[0003]Consider someone hunting for an apartment or a house, for a temporary relocation of 12 months. If she wants to use a corporate housing company, then querying “Oakwood corporate housing” or such on a typical search engine (Google™, Yahoo™ Search, MSN™ Search, Ask.com™) might well satisfy her information need. If, however, she wants to rent from other parties, and knows the location in question well enough, searching through Apartments.com'S™ catalogue might suffice.[0004]However, if she poses her information need as a query in a “conversational manner”, such as “family of two kids, one dog, looking for an apartment o...

Problems solved by technology

However, if she poses her information need as a query in a “conversational manner”, such as “family of two kids, one dog, looking for an apartment or a house, commuting to West Los Angeles, good elementary schools, one year lease”, then no available online tools can return helpful results to her.

The above example reveals that there is a lack of tools helpful to searchers in the common situation of fulfilling projects such as purchasing, shopping, procurement, bartering and requesting for quotes, in “industries” such as online retail, traditional retail, wholesale, health care, travel, real estate, restaurant-going, entertainment, logistics, and sourcing.

The state of the art contains various elements that could be helpful, however, there is no known solution that contains all of the above ingredients.

However, there is the need for deriving industry sector information from a user query, which cannot be done by just extracting proper names.

Such a query might not contain a proper name, or the connection between a proper name to an industry sector is not straightforward.

For example, in purchasing, specifications of a product are highly relevant to a purchasing decision, but many times such specifications are not included in the searcher's initial query, for at least two reasons, one, the searcher might not be aware of, or do not know how to ask about, the specifications (e.g., what is the most number of ports a USB port can have); and two, the initial query would be too complicated if it includes many specifications.

But the state-of-the art addresses generality, and cannot serve the need, some of which are reviewed below.
