20140074811
The proliferation of data creation and storage has resulted in an increased reliance upon various search technologies for identifying and accessing data. Generally speaking, documents or records accessible at a particular location may be indexed by a search engine and data relating to the indexed information can be stored at a database or other data structure accessible to various systems or devices. Thus, when a search query is submitted to a search engine, the search engine can execute the query against the search index, determine if records or documents matching the search query are present in the search index, order the identified records or documents in accordance with a ranking function, and return search results.
The ranking of search results is often based upon popularity of the respective search results and/or a respective determined relevancy to the submitted query. Thus, for example, if a search term appears in a document, the document can be determined to be relevant to the search query. Similarly, clicks on particular results can be logged and used to affect ranking of a document or record corresponding to the particular result in future result sets.
In some instances, however, documents or records identified as being popular and/or relevant may or may not be of interest to a particular entity. As such, ranking of the documents or records in accordance with popularity-based and/or relevance-based considerations may not be helpful to some searchers. Similarly, some documents or records are ranked higher in result sets based upon sponsorship or advertising fees. Thus, highly ranked documents or records may be of little to no interest to a searcher.
It is with respect to these and other considerations that the disclosure made herein is presented.
Concepts and technologies are described herein for query ranking models. In accordance with the concepts and technologies disclosed herein, a search engine can be configured to expose a ranking function used to rank or order search results. The ranking function can be exposed as an object such as a query ranking model object. If an entity accessed the search engine, the query ranking model object can be exposed to the entity, transmitted to the entity, and/or downloaded by the entity. In some embodiments, a computing device accessed the search engine via a web browser or other application.
The computing device can execute a query application and/or can access query application functionality provided by the search engine. The query application can be configured to receive or otherwise obtain the query ranking model object and generate a query ranking model based upon the query ranking model object. The query ranking model can include one or more features. The “features” can include various aspects or considerations of ranking search results that are to be considered by the search engine when ranking the search results. According to various embodiments, the query ranking model can include data specifying weights assigned to the various features of the query ranking model. The computing device can be configured to generate and/or store any number of query ranking models.
The computing device can generate a query and include data with the query identifying the query ranking model that is to be used to rank search results generated by the search engine. In some embodiments, the computing device can be configured to submit the query ranking model as an object that can be submitted with the query. Alternatively, the query ranking model can be identified by a flag or other data included in the query and stored elsewhere such as at the search engine, at a social networking server, with an online profile, and/or elsewhere. As such, a particular query ranking model can be specified for a particular query, if desired.
The computing device also can be configured to manage query ranking models. The computing device can be configured to allow creation, modification, and/or deletion of query ranking models. The weights of features of the query ranking models can be adjusted. Additionally, or alternatively, the features themselves can be adjusted and/or features can be added to and/or removed from the query ranking models. Changes to the query ranking models can be saved and or used for single searches, if desired. In some implementations, query ranking models can be associated with particular devices and/or users of a search engine or other search services or applications. As such, each user or device can use a personalized query ranking model, if desired.

According to some embodiments, the computing device 102 is configured to operate in communication with, or as part of, a communications network (“network”) 104. In some other embodiments, the computing device 102 does not operate in communication with the network 104. The computing device 102 can be configured to execute an operating system 106 and one or more application programs, modules, software elements, or other computer-executable or computer readable instructions such as, for example, a query application 108.
The operating system 106 is a computer program for controlling the operation of the computing device 102. The query application 108 can include an executable program configured to execute on top of the operating system 106 to provide the functionality described herein for creating, modifying, and/or using query ranking models. Although the query application 108 is illustrated as executing at the computing device 102, it should be understood that the query application 108 may be embodied as an application or module executing on a device remote from the computing device 102 such as a web server, a search engine, or the like. Thus, the functionality of the query application 108 described herein can be provided by a server computer or web server that is executed by an application program executing on the computing device 102 such as a web browser or other application program. Therefore, it should be understood that the illustrated embodiment is illustrative, and should not be construed as being limiting in any way.
The query application 108 can be configured to obtain a query ranking model object 110. The query ranking model object 110 can include an object exposed by various applications, services, and/or devices. In some contemplated embodiments, a search engine 112 can be configured to expose the query ranking model object 110 to searchers and/or other entities. Thus, the search engine 112 can be configured to allow searchers or other entities to determine how results generated by the search engine are to be ranked and/or ordered. In some embodiments, as will be described in more detail below, the query application 108 can be configured to obtain the query ranking model object 110, to modify one or more aspects of the query ranking model object 110, and/or to generate a query ranking model 114.
The query ranking model 114 generated by the query application 108 can be submitted to the search engine 112 and used to rank and/or order results identified by the search engine 112 in response to searches performed on behalf of the computing device 102. In some embodiments, the computing device 102 can be configured to submit the query ranking model 114 with a query 116. In some other embodiments, the computing device 102 can be configured to generate and/or modify query ranking models 114 at the search engine 112 and/or other devices such as social networking services (not illustrated), online profile services, or the like. Thus, the computing device 102 can be configured to submit data identifying the query ranking model 114 to be used to rank and/or order results instead of actually submitting the query ranking model 114 with the query 116. Therefore, while the illustrated embodiments are described as including the query ranking model 114 with query 116, it should be understood that this embodiment is illustrative, and should not be construed as being limiting in any way.
As mentioned above, the query application 108 can be configured to modify the query ranking model object 110 to generate the query ranking model 114. In particular, the query application 108 can be configured to obtain the query ranking model object 110 from the search engine 112 and/or elsewhere, and to identify one or more “features” that are included in the query ranking model object 110. As used herein, the term “features” can be used to refer to variables, constants, relationships, and/or other aspects of results generated by the search engine 112 that are to be used in ranking results identified by the search engine 112 in response to queries such as the query 116. Additional aspects of the features, as well as some examples of the features, are illustrated and described in more detail below with reference to
The query ranking model object 110 can identify one or more features included and/or considered as part of the query ranking model object 110, as well as respective weights assigned to each of the included features. The weights can include percentages that define a relative importance of the particular feature in determining a rank or order of a particular hit to be included as part of a result set. In some embodiments, the features can be weighted positively and/or negatively to increase or decrease, respectively, a relative rank of a hit based upon matches between the hit and the features included in the query ranking model object 110. Features also can be weighted to zero to remove consideration of that feature when ranking and/or ordering results in a result set.
According to various embodiments, the query application 108 can be configured to obtain the query ranking model object 110 from the search engine 112 or other location, and to allow users or other entities to modify weights assigned to the various features included in the query ranking model object 110. Additionally, or alternatively, users or other entities can add or remove features included in the query ranking model object 110. The weights and feature additions or other modifications can be captured by the query application 108 and used to generate the query ranking model 114.
According to various embodiments, the query ranking model 114 can be submitted with the query 116 and disposed of immediately thereafter. In some other embodiments, the query ranking model 114 can be stored at the computing device 102, stored at the search engine 112 as associated with a particular profile or device such as the computing device 102, and/or can be stored at other devices or services. In some implementations, the query ranking model 114 can be associated with various devices and/or users of the search engine 112 and/or other search services or applications, and as such, each user or device can use a personalized query ranking model 114. In some embodiments, query ranking models 114 can be stored at social networking services or other services as associated with a particular user, profile, or device and used at various times and/or for various purposes.
The query application 108 can be configured to generate the query 116 and submit the query 116 to the search engine 112. As is generally understood, the computing device 102 can render a search page or search portal using a web browser or other application program, and the query 116 can be submitted to the search engine 112 via the search page or search portal. In response to receiving the query 116, the search engine 112 can perform a search of a search index or other dataset stored at the search engine 112 and/or in communication with the search engine 112. In the illustrated embodiment, the search engine 112 is illustrated as accessing a data store 118 that stores data against which the query 116 is run. It should be understood that the query 116 described herein can include, but is not limited to, web search strings, database queries, enterprise application search queries, or the like. As such, the data store 118 can include or can store a search index, a site index, a document repository, computing device directories, databases, other information, or the like.
The search engine 112 can generate a result set based upon the query 116. In some embodiments, the search engine 112 generates one or more search results 120. The search results 120 can be returned to a searching entity such as the computing device 102.
