Embodiment 1

[0265] Embodiment 1. A method performed by one or more data processing devices, the method comprising: the data processing device receives a search query at the data processing device, the search query specifying attributes shared by a group of related instances; the data processing device Use the data processing device to identify the grouping of instance identifiers in the collection of unstructured electronic documents; use the data processing device to determine the relevance of the grouping of instance identifiers to the search query; use the data processing device to pair instance identifiers At least some of the example identifiers in the grouping of are individually scored; and the data processing apparatus uses the data processing apparatus to rank at least some of the example identifiers according to the scores.

Embodiment 2

[0266] Embodiment 2. The method according to embodiment 1, wherein determining the relevance of the group of instance identifiers to the search query includes: calculating the relevance of the group of instance identifiers to the source document including the group of instance identifiers; calculating the instance identifier The group identified by is actually the likelihood of the grouping of instance identifiers; and the relevance of the source document including the grouping of instance identifiers is calculated with the search query.

Embodiment 3

[0267] Embodiment 3. The method according to embodiment 1, wherein the grouping of identifying instance identifiers includes: forming a first new query that is biased towards identifying grouping; forming a second new query limited to search summary sources; and using the received query, first The new query and the second new query search a collection of unstructured electronic documents.

Abstract

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for improving search with user corrections. In one aspect, a methods performed by a data processing apparatus include the actions of receiving a value result set, accessing historical records of user corrections stored at one or more data storage devices, the historical records describing user corrections of the characterization of instance attributes by values, determining that the historical records of user corrections describe a first user correction involving a first value in the value result set, and changing a confidence parameter embodying a confidence that the first value correctly characterizes the attribute of the instance. The value result set comprises a collection of one or more values. The values are candidates for characterizing an attribute of an instance.; The first value is involved in the correction as either a corrected value or an uncorrected value.

Description

technical field [0001] The present specification relates to improving ranking in search results, eg, by searching unstructured electronic document collections, utilizing user correction or identification of groups of related instances. Background technique [0002] Searching is generally an automated process in which a user enters a search query and receives responsive results in a result set. The results identify content relevant to the search query, eg, in a machine-readable collection of digital data stored on a data storage device. [0003] An electronic document is a collection of machine-readable digital data. Electronic documents are typically individual files and formatted according to defined formats (eg, PDF, TIFF, HTML, XML, MS Word, PCL, PostScript, etc.). An electronic document collection may be stored as digital data on one or more data storage devices. [0004] Electronic document collections can be unstructured or structured. The formatting of documents i...
