Problems solved by technology

It is not actually clear from the user's query which of these people the user is trying to find, but it is likely that the user is only interested in one of them, and a large subset of the results are therefore irrelevant
The inability of search engines to resolve the underlying identities of entity instances in web pages hampers their ability to effectively organize search results

Embodiment Construction

[0010] Described herein is an entity-based search system that detects and identifies entities in Internet-based content and uses this identification to organize search results. One goal of entity detection and disambiguation is to label named entities in web pages (or other types of text data) with distinguishable identifiers that unambiguously identify the entities. The system associates one or more entity identifiers with a web page and stores this information as metadata for the page in a search engine index. This metadata will enable entity-based queries and rich data presentation in search engine results pages (SERPs), including: grouping results by entity; filtering results by one or more specific entities; or User preferences for reranking search results.

[0011] In some embodiments, an entity-based search system includes four high-level components: 1) a knowledge repository, which stores a large collection of known entities; 2) a named entity detector, which detects ...

Abstract

An entity-based search system is described herein that detects and recognizes entities in Internet-based content and uses this recognition to organize search results. The system associates one or more entity identifiers with a web page and stores this information as metadata of the page in a search engine index. This metadata will enable entity-based queries as well as rich data presentations in a search engine result page (SERP), including grouping results by entities, filtering results by one or more particular entities, or re-ranking search results based on user preference of entities. Thus, the entity-based search system allows users to identify a particular entity the user is interested in finding, and to receive search results directly related to that entity.

Description

Background technique [0001] The Internet provides access to a vast amount of information. A major challenge given the amount of information is how to find and discover information to provide users with the most relevant information for a particular context. The most common tool used to accomplish this today is a keyword-based search query provided to a search engine. The search engine matches the received keywords to one or more words or phrases in the search index in order to identify documents, web pages or other content potentially relevant to the user's query. For example, if a user searches for "dinosaurs," the search engine provides the user with a list of search results that are links to web pages that contain the term. [0002] User queries typically contain one or more entities identified by names or attributes associated with the entities (for example, person, location, or organization names). For example, one query might search for "Barack Obama," while another m...
