## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a continuation application of, and claims priority to, U.S. patent application Ser. No. 10/971,853, now U.S. Pat. No. 8,838,562, titled “Methods and Apparatus for Providing Query Parameters to a Search Engine”, filed on Oct. 22, 2004. The disclosure of the foregoing application is incorporated herein by reference in its entirety for all purposes.


FIELD
This invention relates generally to the field of data processing and more particularly to the field of search query processing.
BACKGROUND
Search engines can search large databases for information related to specified search queries. Users typically provide search queries through a search engine's graphical user interface (GUI). For example, a user may provide a search query term by entering text into a GUI textbox designated for receiving search queries in textual form. The user may type the query text into the textbox. Alternatively, the user may “copy” text from an application program and “paste” the text into the search engine's textbox. After the search engine receives the query in its textbox, it searches one or more databases for data containing the query term.
Although “pasting” can reduce the amount typing necessary for entering search query terms, pasting is typically limited to applications that offer selectable text. Additionally, pasting application text into a search engine textbox may require numerous keyboard and pointing device commands. For example, pasting text into a search engine text box may require users to 1) activate an application containing selectable text; 2) select text; 3) “copy” the text; 4) activate a search engine; and 5) paste the text into the search engine's query text box. Therefore, it would be useful to have methods and apparatus for providing search query terms to a search engine.
SUMMARY
Methods and apparatus for providing query parameters to a search engine are described herein. In one embodiment, the method includes receiving selection information, wherein the selection information indicates search data selected from a graphical user interface. The method also includes creating a query parameter based on the search data and presenting the query parameter to a search engine.
In one embodiment, the apparatus includes a selection processing unit to receive one or more selection indicators which define a graphical user interface selection area, the input processing unit to fetch image data or text data appearing in the graphical user interface selection area. The apparatus also includes a query creation unit to access the image data or text data and create a query based on the image data or text data, the query creation unit to transmit the query to a search engine.

System Operations
This section describes operations performed by embodiments of the invention. In certain embodiments, the operations are performed by instructions residing on machine-readable media (e.g., software), while in other embodiments, the methods are performed by hardware or other logic (e.g., digital logic).
In this section, FIGS. 5-7 will be discussed. In particular, FIG. 5 describes operations for processing a selection request, while FIG. 6 describes operations for creating query parameters based on the selection request. FIGS. 7 and 8 describe operations for using additional non-selected data when creating the query parameter.
FIG. 5 is a flow diagram illustrating operations for receiving and processing a selection request, according to exemplary embodiments of the invention. The flow diagram 500 will be described with reference to the exemplary system of FIG. 4. The flow diagram 500 commences at block 502.
At block 502, the selection processing unit 402 receives a first selection request from the selection device 416 via the selection device driver 414. The first selection request is associated with a first location within a GUI. In one embodiment, the first selection request can be a down-mouse-click received from a first location on an application program, such as a word processor, browser, spreadsheet, etc. The flow continues at block 504.
At block 504, the selection processing unit 402 receives a second selection request from the selection device 416 via the selection device driver 414. The second selection request is associated with a second location on the GUI. In one embodiment, the second selection request can be an up-mouse-click received from a second location on the application program. In one embodiment, the down-mouse-click and up-mouse-click together constitute a single mouse-click. In one embodiment, the first and second locations can be used to define a selection area (on the GUI) that includes search data, such as image data and text. The flow continues at block 506.
At block 506, the selection processing unit 402 determines whether there is selectable text at the first GUI location. According to embodiments, the selection processing unit 402 can determine whether there is selectable text at the first GUI location by querying the application program that occupies the first GUI location or by querying the operating system. If there is selectable text at the first GUI location, the flow continues at block 508. Otherwise, the flow continues at block 510.
At block 508, the selection processing unit 402 fetches the selectable text associated with a GUI area defined by the first and second locations. In one embodiment, the first and second locations define a rectangular selection area on the GUI, where the first location defines one of the rectangle's upper vertices and the second location defines one of the rectangle's lower vertices. According to embodiments, the selection processing unit 402 can fetch selectable text from an operating system clip-board or from another memory location. From block 508, the flow ends.
At block 510, the selection processing unit 402 fetches image data associated with an area of the GUI defined by the first and second locations. As noted above, in some embodiments, the first and second locations define a rectangular selection area with a GUI. The selection processing unit 402 can fetch data appearing in the rectangular selection area. From block 510, the flow ends.
Although the flow diagram 500 describes fetching either text or image data from a GUI selection area, other embodiments fetch both text and image data from a GUI selection area. In one embodiment, after receiving the first and second selection requests, the selection processing unit 402 fetches both text and image data appearing in the GUI selection area.
While FIG. 5 describes operations for receiving and processing a selection request, FIG. 6 describes creating query parameters based on data associated with the selection request.
FIG. 6 is a flow diagram illustrating operations for creating a set of one or more query parameters, according to exemplary embodiments of the invention. The flow diagram 600 will be described with reference to the exemplary system shown in FIG. 4. The flow diagram 600 commences at block 602.
At block 602, the query creation unit 404 accesses query data. In one embodiment, the query data can be text data and/or image data fetched by the selection processing unit 402, as a result of operations of flow diagram 500 (See FIG. 5). However, alternative embodiments do not require that the text data and/or image data be fetched in any particular fashion. The flow continues at block 604.
At block 604, the query creation unit 404 determines whether the query data is text data. If the query data is text data, the flow continues at block 608. Otherwise, the flow continues at block 606.
At block 606, the conversion unit 406 converts the query data into text. In one embodiment, the conversion unit 406 can use optical character recognition to convert image data into text. The flow continues at block 608.
At block 608, the text processing unit 410 processes the text. In one embodiment, the text processing unit 410 modifies the text by adding characters to or deleting characters from the text. The discussion of FIGS. 7 and 8 below describes additional operations for processing the text. The flow continues at block 610.
At block 610, the text processing unit 410 creates a set of one or more query parameters based on the processed text. In one embodiment, the text processing unit 410 can create a query parameter from the converted and processed text. In one embodiment, the text processing unit 410 can create another query parameter based on the language of the converted text (see discussion of block 702 below). In one embodiment, the text processing unit 410 can create yet another query parameter based on context words taken from the GUI (see discussion of block 708 below). The flow continues at block 612.
At block 612, the text processing unit 410 transmits the set of one or more query parameters to the search engine 412. In one embodiment, the text processing unit 410 inserts the processed text into a URL and transmits the URL to a search engine via a browser. From block 612, the flow ends.
The discussion of FIGS. 5 and 6 above described operations for receiving a selection request and creating a set of one or more query parameters. In one embodiment, creating a query parameter set involves processing text (see block 608 of FIG. 6). In the discussion below, FIGS. 7 and 8 describe more detailed operations for processing text, according to embodiments of the invention.
FIG. 7 is a flow diagram illustrating operations for processing text, according to exemplary embodiments of the invention. The operations of the flow diagram 700 will be described with reference to the exemplary system of FIG. 4. The operations of the flow diagram 700 will also be described with reference to FIG. 8 (see discussion of blocks 704, 706, and 708 below). The flow diagram 700 commences at block 702.
At block 702, the text processing unit 410 determines a language of the text. For example, the text processing unit 410 can determine whether the text is English, French, Spanish, Chinese, etc. The flow continues at block 704.
At block 704, the text processing unit 410 completes partial words. In one embodiment, the text processing unit 410 can complete partial words using unselected text data and/or image data appearing in the GUI. FIG. 8 helps illustrate this concept.
FIG. 8 is a block diagram illustrating creating query parameters using text from a GUI, according to exemplary embodiments of the invention. FIG. 8 includes a text passage 800, which includes a selected text segment 802. The selected text segment 802 includes the characters “Jaguars are lar”. The passage 800 also includes an unselected text segment 806, which includes the characters “ge”.
According to one embodiment, the text processing unit 410 can append characters to a selected text string using unselected text segments from the GUI. For example, the text processing unit 410 could complete the string “Jaguars are lar” 802 by appending it with “ge” 806, forming “Jaguars are large”. Completing words may result in query parameters that produce more accurate searches.
Referring back to FIG. 7, from block 704, the flow continues at block 706.
At block 706, the text processing unit 410 deletes certain words from the text. In one embodiment, the text processing unit 410 can delete “stop words”, such as articles, prepositions, and other common words. Deleting words from the text may result in query parameters that produce more accurate search results. The flow continues at block 708.
At block 708, the text processing unit 410 augments the text with context words. In one embodiment, the text processing unit 410 can augment the text with unselected text from the GUI. For example, referring to FIG. 8, the text processing unit can augment the query “Jaguars are large” with one or more unselected context words 804. Because “Jaguars” can relate to cats or automobiles, the text processing unit 410 can search for unselected context words in the passage 800. The text processing unit 410 can add one or more context words 804 to the query. For example, the text processing unit 410 can add “cats” to the query. Adding context words may result in query parameters that produce more accurate search results. From block 708, the flow ends.
Although the flow diagram 700 describes a sequence of text processing operations, embodiments of the invention can employ one or more of the text processing operations described above.
Exemplary Implementation
In this section, an exemplary implementation will be described. While this section describes an exemplary implementation, other embodiments of the invention can be implemented differently. In this section, FIG. 9 describes exemplary operations for creating a query parameter, whereas FIGS. 10-12 show screenshots of a user interface.
FIG. 9 is a flow diagram illustrating operations for providing a query parameter set to a search engine, according to exemplary embodiments of the invention. FIG. 9 will be described with reference to the exemplary system of FIG. 4. In the following discussion, the selection device 416 will be referred to as a mouse and the selection device driver 414 will be referred to as a mouse driver. The flow diagram 900 commences at block 904.
At block 904, the mouse generates a down-mouse-click signal (in response to a user click) and the mouse driver converts the signal into a down-mouse-click indicator and screen coordinate information. The screen coordinate information can include an (x,y) coordinate pair representing a location of a mouse pointer on a GUI. The down-mouse-click indicator can be a data structure suitable for processing by the selection processing unit 402. In one embodiment, the mouse can be a four-button mouse for which a button has been configured for receiving selection input for a query parameter creation system. The flow continues at block 906.
At block 906, the selection processing unit 402 determines whether there is selectable text at the screen coordinates. If there is selectable text at the screen coordinates, the flow continues at block 910. Otherwise, the flow continues at block 908.
At block 908, the selection processing unit 402 draws a resizable window anchored at the screen coordinates. FIG. 10 helps to illustrate this concept. FIG. 10 is a screenshot illustrating image selection in a GUI, according to exemplary embodiments of the invention. In FIG. 10, in response to input from the mouse, the selection processing unit 402 creates a resizable window 1004 (i.e., a selection area) anchored at a screen point 1008. The selection processing unit 402 resizes the window 1004 based on the position of the mouse pointer 1006. The flow continues at block 912.
At block 910, the selection processing unit 402 highlights text between the coordinates and the current mouse pointer position. FIG. 11 helps to illustrate this concept. FIG. 11 is a screenshot illustrating text selection in a GUI, according to exemplary embodiments of the invention. In FIG. 11, the selection processing unit 402 highlights text 1102 between a first screen point 1106 and the mouse pointer 1104. Referring to FIG. 9, the flow continues at block 912.
At block 912, in response to a user up-click, the mouse generates an up-mouse-click signal and the mouse driver converts the signal into a up-mouse-click indicator and screen coordinate information. The flow continues at block 913.
At block 913, the selection processing unit 402 fetches data associated with the GUI area defined by the coordinates. For example, referring to FIG. 10, the selection processing unit 402 fetches the image data appearing in the window 1004. As another example, referring to FIG. 11, the selection processing unit 402 fetches the selected text 1102 (i.e., the selection processing unit 402 fetches “mouse ran up the clock”). In one embodiment, when the screen coordinates indicate that the down-mouse click and up-mouse click occurred at the same GUI location, the selection processing unit 402 can fetch a single word closest to the coordinates. In one embodiment, the selection processing unit 402 can perform OCR on a GUI area surrounding the screen coordinates. After performing the OCR, the selection unit processing 402 can then fetch the word closest to the coordinates. Alternatively, the selection processing unit can fetch any number of words from an area surrounding the coordinates. The flow continues at block 914.
At block 914, the conversion unit 406 determines whether the data is image data. If the data is image data, the flow continues at block 918. Otherwise, the flow continues at block 916.
At block 918, the conversion unit 406 converts the image data into text using optical character recognition. The flow continues at block 916.
At block 916, the query creation unit 404 creates a query parameter using the text and the query creation unit 404 creates a universal resource locator (URL) based on the query parameter. For example, the query creation unit 404 creates a query parameter using “the mouse ran up the clock”. Additionally, the query creation unit 404 creates the following URL based on the query parameter: http://www.google.com/search?hl=en&ie=UTF-8&q=mouse+ran+up+the+clock The flow continues at block 920.
At block 920, the query creation unit 404 launches a browser and inserts the URL into the browser's address bar. FIG. 12 illustrates this concept. FIG. 12 is a screenshot illustrating inserting a query parameter set into a browser address bar. In FIG. 12, a browser 1200 is launched and a URL including the query parameter from above is inserted into the browser's address bar. Launching the browser and inserting the URL into the browser's address bar transmits the query parameter to a search engine. From block 920, the flow ends.
