## Title
User interface for recommended alternative search queries

## Abstract

Alternative search queries are provided by: determining alternative search paths for terms in a current search query; receiving a user selection of one or more terms in the current search query; providing a graphical display of one or more alternative search paths for the selected terms; receiving a user selection of at least a portion of one of the alternative search paths to be a new search query; and displaying search results for the new search query. The new search query may then become the current search query, and the determining of the alternative search paths, the receiving of the user selection of the one or more terms in the current search query, and the providing of the graphical display of alternative search paths for the selected terms are performed for the new search query as the current search query.

## Background
BACKGROUND
Keyword searches using a search engine are common today. When a search engine does not return the desired results, users often have to guess what other alternative search terms or words queries they may use to render the desired search results. For example, a user may have a problem with his computer and has done a number of searches on a search engine using various combinations of terms but is unable to find the solution the user seeks. As the user enters the keyword(s), the search engine displays some alternative search terms using a “type ahead” feature. However, the search engine offers no or very little other information concerning these alternative search terms. Thus, the user again has to guess which alternative search term(s) may lead to the desired search results.
SUMMARY
According to one embodiment of the present invention, a computer implemented method for providing a user interface for recommending alternative search queries determines one or more alternative search paths for one or more terms in a current search query, receives a user selection of one or more terms in the current search query; provides a graphical display of one or more alternative search paths for the selected terms, receives a user selection of at least a portion of one of the alternative search paths to be a new search query, and displays search results for the new search query.
System and computer program products corresponding to the above-summarized methods are also described and claimed herein.

Embodiments according to the present invention expand on the capabilities within the user interface of search engines to enable users to render alternate search queries that could lead them to the information that they are seeking. The user may select one or multiple terms within the search query to initiate an alternate query. A processing engine compares the current search query against historical search data and search analytics data to provide an output of alternative search paths in the user interface. The processing engine further renders a user interface to provide a visual of the alternative paths of search terms related to the search query. The user selects an alternative search query by navigating the alternative search paths displayed on the user interface. Optionally, the user may be provided the ability to customize the display of the alternatives search paths.
FIG. 1 illustrates an embodiment of a system for providing a user interface for recommending alternative search queries according to the present invention. The system includes a client device 101 with access to a processing engine 102 that provides alternative search paths for a search query according to the present invention. The processing engine 102 works in conjunction with a search engine 103 typically provided over a network, such as the Internet. The processing engine 102 may be implemented in different ways, including but not limited to a client side application, built into the search engine 103, or on the server side with privileges to access data on the client device 101. The processing engine 102 has access to historical search data 104 and search analytical data 105 in determining the alternative search paths, as described further below. The processing engine 102 further has access to any user preferences 106 for customizing the display of alternative search paths.
FIG. 2 illustrates an embodiment of a client device according to the present invention. The client device 100 includes a computer system 200 operationally coupled to a processor or processing units 206, a memory 201, and a bus 209 that couples various system components, including the memory 201 to the processor 206. The bus 209 represents one or more of any of several types of bus structure, including a memory bus or memory controller, a peripheral bus, an accelerated graphics port, and a processor or local bus using any of a variety of bus architectures. The memory 201 may include computer readable media in the form of volatile memory, such as random access memory (RAM) 202 or cache memory 203, or non-volatile storage media 204. The memory 201 may include at least one program product having a set of at least one program code module 205 that are configured to carry out the functions of embodiments of the present invention when executed by the processor 206. The computer system 200 may also communicate with one or more external devices 211, such as a display 210, via I/O interfaces 207. The computer system 200 may communicate with one or more networks 212 via network adapter 208.
FIG. 3 is a flowchart illustrating an embodiment of a method for providing a user interface for recommending alternative search queries according to the present invention. The processing engine 102 receives a current search query, which includes one or more terms, entered by a user of the search engine 103 (301). The processing engine 102 determines one or more alternative search paths for the terms in the current search query (302). In this embodiment, in determining the alternative search paths, the processing engine 102 compares the terms in the current search query against the historical search data 104 and the search analytical data 105. Example historical search data and search analytical data include but is not limited to: alternative results based on the user's historical searches; historical search results data or analytics gathers from other users to recommend additional or alternative words; and alternative variances for the search terms. At some point in time, the processing engine 102 receives a user selection of one or more of the terms in the current search query (303). For example, the user makes the selection after determining that the current search query does not return the desired results. In response, the processing engine 102 provides a graphical display of the alternative search paths for the selected terms within the search engine user interface (304). The graphical display includes graphical elements corresponding to alternative search terms which provide the user with a visual of different paths of search terms that may lead to a more desirable search result. The graphical display may be rendered in many different ways that allow the user to navigate the alternative search paths and to select at least a portion of one of the paths to be the new search query, as described further below. Default display structure and display settings may be used, which may be customized via the user preferences 106. In response to receiving the user selection of at least a portion of one of the paths (305), the processing engine 102 submits this new search query to the search engine 103, which returns a result of the new search. The processing engine 102 then displays the search results for the new search query (306). In this embodiment, the processing engine 102 may again determine alternative search paths for the new search query as the current search query, and the process (302-306) may then be repeated. In this manner, the user may hone the search in an iterative manner until the desired search results are obtained.
FIGS. 4A-4D illustrate example graphical displays on the user interface according to embodiments of the present invention. FIG. 4A illustrates a hierarchical or decision tree example. FIG. 4B illustrates a word cloud example. FIGS. 4C-4D illustrate bubble examples. Referring to FIG. 4A, assume that the user enters “Product Version 7.0” as the current search query. In response to receiving this current search query (301), the processing engine 102 determines the alternative search paths for the terms in the current search query (302). Assume that the user selects the term “Product” 401. In response to receiving the selection of “Product” 401 (303), the processing engine 102 provides a hierarchical or decision tree of the alternative search paths for “Product” (304). In this example, the paths are illustrated as branches that include “Support Portal” 402, “Application Server” 403, and “OS” 404. The position and size of the words in the paths indicate the likelihood of interest, for example, with the words that are larger and/or closer to the term “Product” 400 indicating a higher likelihood of interest. Optionally, based on the user preferences 106, the processing engine 102 may render different colors (represented by different shadings) and percentages 405-407 of confidence of each alternative term based on the estimation by the processing engine 102 that the path being suggested would be of interest to the user. To select a new search path, the user navigates the tree and selects the path from “Product” 400 to “Support Portal” 402 by clicking on the graphical display of the terms with a mouse, touching the display of the terms with a finger or stylus on a touchscreen, tracing a path from the display of “Product” 400 to the display of “Support Portal” 402 on the touchscreen using a swipe gesture, hovering over the terms in the path, or by voice commands. Upon receiving the selection of the “Product” to “Support Portal” search path (305), the processing engine 102 displays the search results (not shown) for the new search query of “Product Support Portal” (306). In this example, the processing engine 102 may again determine alternative search paths for the “Product Support Portal” as the current search query, and the process (302-306) may then be repeated.
Referring to FIG. 4B, assume that in response to receiving the selection of “Product” 401 (303), the processing engine 102 provides a word cloud of the alternative search paths for “Product” (304). In this example, the paths are illustrated as a cloud of alternative terms of varying sizes, positions, and/or colors (represented by differing shades). For example, based on the user preferences 106, the color (represented by differing shades) depicts the likelihood of interest, and the size of the word depicts the number of previous searches from other users based on historical and analytical data and/or the likelihood that is would be of interest to the user. The user may then select a path including “support” 410 and “portal” 411 among the terms in the word cloud to be the new search path. The different manners of selection as described above with FIG. 4A may be used here as well. Upon receiving the selection of the “support portal” search path (305), the processing engine 102 displays the search results (not shown) for the new search query of “Product Support Portal” (306). In this example, the processing engine 102 may again determine alternative search paths for the “Product Support Portal” as the current search query, and the process (302-306) may then be repeated.
Referring to FIG. 4C, assume that each term in the current search query are displayed in a separate bubble. In this example, “Product”, “Version”, and “7.0” are displayed in separate bubbles 420-422. In response to receiving the selection of “Product” bubble 420 (303), the processing engine 102 provides additional bubbles extending from the “Product” bubble 420 that display alternative search paths for “Product” (304). The bubbles are illustrated in varying sizes, positions, and/or colors (represented by differing shades). For example, based on the user preferences 106, the size of the bubble may depict the number of previous searches from other users based on the historical and analytical data and/or the likelihood that it would be of interest to the user. In this example, the bubbles are displayed in a hierarchical or tree structure, with the bubble sizes being smaller with each level of sub-branches in the hierarchy. Here, the “Product” bubble 420 has three sub-bubbles: “Application Server” 423; Process Server” 424; and “infocenter” 425. The “infocenter” bubble 425 has two sub-bubbles: “7.0” 426 and “8.0” 427. The “7.0” bubble 426 has two sub-bubbles: “deploy” 428 and “install” 429. The “install” bubble 429 has two sub-bubbles: “Alone” 430 and “Network” 431. The user may then select a path of bubbles to indicate the terms to be the new search path. Illustrated in this example, the user selects the bubbles for “Product infocenter 7.0 install Network” as the new search path. The different manners of selection as described above with FIG. 4A may be used here as well. Upon selection, the bubbles in the selected path are displayed with a different color or shading than the non-selected bubbles, per the user preferences 106. Optionally, other graphical displays may be added to provide additional information. For example, the bubbles may be color coded to indicate the likelihood of relevancy.
In this embodiment, one or more levels of sub-bubbles are displayed as the user navigates to a bubble. When the user navigates to a bubble, the display of the bubble may be changed to reflect the navigation, such as by a color change. For example, the processing engine 102 initially displays the sub-bubbles of the “Product” bubble 420, with bubbles “Application Server” 423, “Process Server” 424, and “infocenter” 427 only. Upon the user's navigation to the “infocenter” bubble 425, the processing engine 102 displays the sub-bubbles “7.0” 426 and “8.0” 427. If the user had navigated to the “Application Server” bubble 423 instead of or backtracking from the “infocenter” bubble 425, the sub-bubble(s) of the “Application Server” bubble 423 (not shown), would be displayed.
Alternatively, multiple levels of bubbles may be displayed based on a user profile or previous searches by the user. For example, upon the selection of the “Product” bubble 420, the processing engine 102 may display the search path from the “infocenter” bubble 425 to the “install” bubble 429. The user could have recently registered the product during installation, as reflected by the user profile. Thus, the processing engine 102 displays this path with a higher priority.
Assume that the processing engine 102 receives the selection of the “Product infocenter 7.0 install Network” search path (305). In response, the processing engine 102 displays the search results (not shown) for the new search query of “Product infocenter 7.0 install Network” (306). In this example, the processing engine 102 may again determine alternative search paths for the “Product infocenter 7.0 install Network” as the current search query, and the process (302-306) may then be repeated.
As in FIG. 4C, FIG. 4D illustrates each term in the current search query being displayed in a separate bubble. However, in FIG. 4D, the user selects multiple terms in the current search query. In this example, assume the user selects “Product Version 7.0”, the entire current search query. In response to receiving the selection of “Product Version 7.0” (303), the processing engine 102 provides additional bubbles extending from the selected group of terms that display alternative search paths for “Product Version 7.0” (304). Here, the “Product Version 7.0” bubbles 421-422 have three sub-bubbles: “Product Configuration 1” 440; “Product Configuration 2” 441; and “Product Server Version 7” 442. The “Product Server Version 7” bubble 442 has three sub-bubbles: “Download” 443; “Product documentation” 444; and “System requirements” 445. The “System requirements” bubble has two sub-bubbles: “hardware” 446 and “software” 447. The “software” bubble 447 has four sub-bubbles: “OS1” 448; “OS2” 449; “OS3” 450; and “OS4” 451. The user may then select a path of bubbles to indicate the terms to be the new search path. Illustrated in this example, the user selects the bubbles for “Product Server Version 7 System requirements software OS3” as the new search path. The different manners of selection as described above with FIG. 4A may be used here as well. The bubbles in the selected path are displayed with a different color or shading than the non-selected bubbles, per the user preferences 106. Optionally, other graphical displays may be added to provide additional information. For example, the bubbles may be color coded to indicate the likelihood of relevancy.
Upon receiving the selection of “Product Server Version 7 System requirements software OS3” search path (305), the processing engine 102 displays the search results (not shown) for the new search query of “Product Server Version 7 System requirements software OS3” (306). In this example, the processing engine 102 may again determine alternative search paths for the “Product Server Version 7 System requirements software OS3” as the current search query, and the process (302-306) may then be repeated. As illustrated in FIGS. 4C-4D, the selection of multiple terms in the search query may lead to different alternative search paths than when a single search term is selected.
FIGS. 5A-5C illustrate examples of user navigation of alternate search paths on a touchscreen according to embodiments of the present invention. FIG. 5A illustrates the user selecting multiple search terms using a “swipe” gesture across all three bubbles for “Product”, “Version” and “7.0”. FIGS. 5B and 5C illustrate the user controlling the number of levels of sub-bubbles to display using “pinch” or “stretch” gestures for collapsing or expanding, respectively, on a touchscreen. For example, as illustrated in FIG. 5B, assume that the processing engine 102 displays the alternative search path from the Product Server Version 7” bubble 442 to the “OS3” bubble 450. The user may initially place one finger on or near the “Product Server 7” bubble 442, place another finger on or near the “OS3” bubble 450, and move the fingers together in a “pinch” gesture. In response, the processing engine 102 changes the graphical display to collapse the search path to display fewer levels. Similarly, as illustrated in FIG. 5C, assume that the processing engine 102 initially display the alternative search path from the “Product Server Version 7” bubble 442 to the “System requirements” bubble 445, the user may place both fingers on or near this path and move the fingers apart in a “stretch” gesture. In response, the processing engine 102 expands the search paths extending to display additional levels of sub-bubbles.
FIGS. 4A-4D and FIGS. 5A-tC are provided for illustrative purposes. Other ways or combination of ways for rending the graphical display of alternative search paths, and/or other ways of navigating the alternative search paths, may be used without departing from the spirit and scope of the present invention.
The descriptions of the various embodiments of the present invention has been presented for purposes of illustration, but are not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The terminology used herein was chosen to best explain the principles of the embodiments, the practical application or technical improvement over technologies found in the marketplace, or to enable others of ordinary skill in the art to understand the embodiments disclosed herein.
