Method of and system for inferring user intent in search input in a conversational interaction system
First Claim
1. A method of inferring user intent in a search input based on resolving ambiguous portions of the search input, the method comprising:
- providing access to a set of content items, each of the content items being associated with metadata that describes the corresponding content item, the metadata associated with the content items including a mapping of relationships between entities associated with the content items;
receiving search input from a user, the search input being intended by the user to identify at least one desired content item, wherein the search input comprises;
a first portion comprising at least one specified entity, anda second portion comprising a reference to at least one unspecified entity related to the at least one desired content item, wherein the at least one unspecified entity of the second portion and the at least one specified entity of the first portion are different;
without further user input;
inferring a possible meaning for the at least one unspecified entity of the second portion based on the at least one specified entity and the mapping of relationships between entities;
based on the inferred possible meaning for the at least one unspecified entity, the at least one specified entity, and the metadata associated with the content items of the set of content items, selecting at least one common content item from the set of content items, wherein the at least one common content item is related to each of the at least one specified entity and the at least one unspecified entity in the mapping of relationships; and
presenting the selected at least one common content item to the user in response to the search input received from the user.

Abstract
A method of inferring user intent in search input in a conversational interaction system is disclosed. A method of inferring user intent in a search input includes providing a user preference signature that describes preferences of the user, receiving search input from the user intended by the user to identify at least one desired item, and determining that a portion of the search input contains an ambiguous identifier. The ambiguous identifier is intended by the user to identify, at least in part, a desired item. The method further includes inferring a meaning for the ambiguous identifier based on matching portions of the search input to the preferences of the user described by the user preference signature and selecting items from a set of content items based on comparing the search input and the inferred meaning of the ambiguous identifier with metadata associated with the content items.

10. A system for inferring user intent in a search input based on resolving ambiguous portions of the search input comprising:
one or more processors configured to; provide access to a set of content items, each of the content items being associated with metadata that describes the corresponding content item, the metadata associated with the content items including a mapping of relationships between entities associated with the content items; receive search input from a user, the search input being intended by the user to identify at least one desired content item, wherein the search input comprises; a first portion comprising at least one specified entity, and a second portion comprising a reference to at least one unspecified entity related to the at least one desired content item, wherein the at least one unspecified entity of the second portion and the at least one specified entity of the first portion are different; without further user input; infer a possible meaning for the at least one unspecified entity of the second portion based on the at least one specified entity and the mapping of relationships between entities; based on the inferred possible meaning for the at least one unspecified entity, the at least one specified entity, and the metadata associated with the content items of the set of content items, select at least one common content item from the set of content items, wherein the at least one common content item is related to each of the at least one specified entity and the at least one unspecified entity in the mapping of relationships; and present the selected at least one common content item to the user in response to the search input received from the user.
