Abstract

A search engine for objects in a corpus of document dynamically evaluates search rank of the objects through Natural Language Processing and machine learning. When a search query is received for a first object, the search engine identifies search results including a plurality of source values that are tied to the first object in the corpus of published documents. A search rank is computed for each identified search result based on content of direct textual references to each of the plurality of source values within the corpus of published documents, as well as a weight assigned to each published document. The identified search results are returned according to the computed search rank.

Claims20

Dependent claims

A system to develop a search engine rank for objects in a corpus of published documents, the system comprising:

a resource database including the corpus of published documents, wherein published documents in the corpus of published documents contain source values and objects tied to the source values based on semantic text analysis of the corpus of published documents wherein the source values are a source of the objects;
a search engine user interface configured to receive a search query specifying a first object;
a processor, and
a memory storing instructions that when executed cause the processor to:
identify search results including a plurality of source values that are tied to the first object in the resource database;
compute a search rank for each of the identified search results based on:
content of direct textual references to each of the plurality of source values within the corpus of published documents;
and
a weight assigned to each published document in the corpus of published documents in which the direct textual references occur, the weight for each published document assigned based on one or more of time related factors, independently assigned peer rankings, or citation frequency factors;
and
return the identified search results according to the computed search ranks.

8 more elements

A non-transitory computer-readable medium storing instructions that when executed cause one or more processors to perform a method to develop a search engine rank for objects in a corpus of published documents, the method comprising:

storing the corpus of published documents, wherein published documents in the corpus of published documents contain source values and objects tied to the source values based on semantic text analysis of the corpus of published documents wherein the source values are a source of the objects;
receiving a search query specifying a first object;
identifying search results including a plurality of source values that are tied to the first object in the corpus of published documents;
computing a search rank for each of the identified search results based on:
content of direct textual references to each of the plurality of source values within the corpus of published documents;
and
a weight assigned to each published document in the corpus of published documents in which the direct textual references occur;
and
returning the identified search results according to the computed search ranks.
