Technique for customizing displayed content

Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to customize displayed content in a document, such as a web page or a user interface in a software application. In particular, by monitoring user activities while one or more users view the document during multiple sessions, the computer system can identify the most relevant content at a particular time. Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity. For example, the computer system may selectively filter the content in the document so that a subset of the content is displayed. Moreover, the displayed content may be dynamically revised based on subsequent user actions.

BACKGROUND

The present invention relates to techniques for customizing displayed content in a document based on user activity.

When presenting information to a user, it is often challenging to make sure that it is easy to understand and to use. These challenges are even greater in dynamic environments where the information is changing and growing in size.

For example, many websites, such as social networks, encourage users to contribute content, which is then instantaneously displayed on the websites. However, over time, popular websites can become very complicated, including multiple types of content, multiple ‘conversations’ (in which groups of users interact with each other), and multiple links to related websites. As a consequence, these websites can become visually cluttered, which makes it increasingly difficult for users to find relevant or interesting information on them (such as recently added or popular content). This degradation in the ability of users to effectively use such websites has a negative impact on the user experience, which can limit or even decrease the popularity of these websites, with a commensurate impact on advertising revenue.

Similar problems occur in user interfaces. For example, many software applications include multiple functions. However, as the number of functions grows, it becomes increasingly difficult for users to find desired functions amid a sea of possibilities. Consequently, most users are only aware of and only use a small subset of the capabilities of a given software application, which obviates the advantages of the unused (indeed, often unknown) capabilities. In addition, the need to maintain a familiar (albeit crowded) user interface prevents software developers from adding new features or improving suboptimal user interfaces.

SUMMARY

One embodiment of the present invention provides a computer system that customizes displayed content in a document. During operation, the computer system monitors user activity while one or more users view the document during multiple sessions. Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity.

This selective modification of the displayed content may involve selectively filtering content in the document so that a subset of the content is displayed, where the displayed content includes one or more icons that, when activated, allow the one or more users to access a remainder of the content. For example, the one or more icons may include one or more links to additional documents. Moreover, if a given icon is activated by a given user, at least some of the remainder of the content may be displayed in the document.

Note that the selective filtering may be performed dynamically as the user activity evolves or changes. For example, the computer system may adjust the displayed content based on user activity after the selective modification. Thus, if one or more users activate the given icon to display content that is currently hidden, this content may be subsequently added to the displayed content.

Additionally, the selective modification may involve altering a format of at least a portion of the displayed content, such as highlighting the portion of the displayed content.

A wide variety of documents may be customized, including: a user interface for a software application; a social forum that is viewed by multiple users who can add content to the document; and/or a web page that is accessed via a network. For example, the displayed content may include one or more functions of the software application, and the selective modification may limit a total number of function icons in the user interface to a pre-determined range of numbers.

Note that the multiple sessions may include one or more previous sessions and/or current sessions for the one or more users. Moreover, the one or more users may include a group of users. Alternatively, the one or more users may include an individual, thereby allowing the displayed content to be personalized.

In some embodiments, the selective modification is based on user activity of the group of users while viewing multiple documents (which include the document). Moreover, the selective modification may be based on a data rate of a link to a device that displays the displayed content. Additionally, the selective modification may be based on a weighted summation of user activities, where different weights are associated with different subsets of the content in the document and different user activities.

Another embodiment provides a method including at least some of the above-described operations.

Another embodiment provides a computer-program product for use in conjunction with the computer system.

DETAILED DESCRIPTION

Embodiments of a computer system, a method, and a computer-program product (e.g., software) for use with the computer system are described. These embodiments may be used to customize displayed content in a document, such as a web page or a user interface in a software application. In particular, by monitoring user activities while one or more users view the document during one or more sessions, the computer system can identify the most relevant content at a particular time. Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity. For example, the computer system may selectively filter the content in the document so that a subset of the content is displayed. Moreover, the displayed content may be dynamically revised based on subsequent user actions.

By dynamically customizing the displayed content, the computer system and the technique allow providers of websites and developers of software applications to significant increase the usefulness of their products. In contrast with existing products, these embodiments allow users to readily find and use relevant content in products that include dynamic user-supplied content and/or multiple functions/features. Moreover, companies can readily update or modify these products without confusing or alienating customers. This ease of use increases customer productivity, customer satisfaction and customer loyalty. It may also allow the products to be differentiated in the marketplace, with a commensurate impact on revenue and profitability.

We now describe embodiments of a computer system, a method, and software for customizing displayed content in a document.FIG. 1Apresents a drawing illustrating a web page100that includes user-supplied content110at different locations, such as location112-1. For example, in many collaborative systems (such as social networks, forums, blogs, online reviews, and online encyclopedias), users are encouraged to provide content and comments, thereby creating a virtual environment that promotes social interaction. However, as these virtual ‘conversations’ and exchanges of information progress, the amount of content on a given web page increases. Eventually, web pages (such as web page100) become unwieldy, because there is too much content and users are no longer able to navigate these web pages to find relevant content, e.g., content that is of interest to them.

This problem can be addressed by selectively modifying the displayed content based on content that is relevant or of interest to one or more users. For example, the relevant content may be identified by monitoring user activities (such as accessing or providing content110) while one or more users view or interact with web page100during one or more sessions (including one or more previous sessions and/or current sessions of the one or more users). Such customizing of content110in web page100is shown inFIG. 1B, which presents a drawing illustrating a web page120. In particular, content110in web page100(FIG. 1A) has been selectively filtered so that a subset122of this content is displayed in web page120. A remainder of the content110in web page100(FIG. 1A) may be hidden, minimized and/or less prominent in web page120. In addition, a format124of at least a portion of the displayed content in web page120(such as content110-7) may be altered (relative to the format in web page100inFIG. 1A), thereby highlighting at least the portion of the displayed content. This format change can include: a different font, a different color, bold characters, underlining, and/or additional visual or audio effects.

Web page120may also include one or more icons126(which may include links to additional web pages) that, when activated, allow users to access the remainder of the content110in web page100(FIG. 1A), which is hidden or not displayed prominently in web page120. If a user activates an icon, such as icon126-1, at least some of the remainder of the content110in web page100(FIG. 1A) may be displayed. This is shown inFIG. 1C, which presents a drawing illustrating a web page130that displays additional content132in addition to the displayed content in web page120(FIG. 1B).

The selective filtering of content in web page120(FIG. 1B) may be dynamically updated or revised as the user activities evolve or change. Thus, computer systems200inFIG. 2 and 300inFIG. 3, which can be used to implement the selective modifying, can ‘learn’ what constitutes the relevant content for a given user at a particular time. For example, the displayed content may be adjusted based on user activity after the initial selective modification of web page100(FIG. 1A). Thus, if one or more users activate icon126-1(FIG. 1B) to display additional content132, this additional content may eventually be added to the displayed content in web page120(FIG. 1B). Similarly, additional content, which is provided by users after the initial selective modification of web page100(FIG. 1A), may be added to the displayed content in web page120(FIG. 1B).

In an exemplary embodiment, the selective modification is based on a weighted summation of user activities, where different weights may be associated with: different subsets of the content110in web page100(FIG. 1A) that the one or more users provided or accessed (for example, by clicking on links or icons, such as those that expand or minimize content), and/or different user activities (such as when users accessed content, did not access the content, and/or provided the content). If the weighted summation of the user activities associated with a subset of content110in web page100(FIG. 1A) is less than a threshold, then this subset may not be included in the subsequently displayed content in web page120(FIG. 1B). Alternatively or additionally, another subset of the content that is of interest (such as content that is popular, e.g., which is viewed regularly and which has a weighted sum that exceeds a threshold) may be highlighted in the displayed content in web page120(FIG. 1B). Note that different thresholds may be used for the weighted summations for user activities associated with different subsets of the content110in web page100(FIG. 1A).

Additional factors or variables may be used to determine how to selectively modify the content in web page100(FIG. 1A), for example, by changing the different weights that are used when determining weighted summations of user activities. In particular, the displayed content in web page120(FIG. 1B) may be based on user preferences in a user profile (such as metadata), which is provided by the one or more users during a registration procedure. These user preferences may include topics or subjects that a user is interested in or that the user doesn't like. Alternatively or additionally, the selective modification may be based on a data rate of a link to an electronic device that displays the displayed content in web page120(FIG. 1B). For example, communication with a portable electronic device (such as a cellular telephone) via a network may have reduced bandwidth relative to another electronic device (such as a desktop computer). As a consequence, subset122(FIG. 1B) in web page120(FIG. 1B) may include less content when displayed on a portable electronic device than when displayed on the other electronic device.

This technique for customizing displayed content may be used to customize the content displayed for individual users. Thus, the one or more users may include one user, thereby allowing the displayed content in web page120(FIG. 1B) to be personalized.

However, such personalization of content can be difficult, especially if it is based on very limited statistics (such as when the one user hasn't visited or viewed the content110on web site100inFIG. 1Avery often or for very long). This problem may be addressed by aggregating user activity for the one user which is associated with multiple (related) web pages (including web page100inFIG. 1A). Alternatively, collaborative filtering may be used, i.e., the one or more users may include a group of users, and the user activities of this group may be used to selectively modify the content110in web page100(FIG. 1A) when it is displayed in web page120(FIG. 1A) for members of this group and/or for other individuals who have similar interests (e.g., as indicated by their user preferences). Once again, the user activities for the group may be associated with multiple (related) web pages (including web page100inFIG. 1A).

This technique for customizing displayed content may be used with a wide variety of documents in addition to web pages, including a user interface for a software application. For example,FIG. 1Dpresents a drawing illustrating a user interface140of a software application in which there are multiple features/functions that are arranged in a menu150in groups152. If a user activates or clicks on a symbol for a given group (such as group152-2), function icons154are displayed. However, if there are too many groups152and/or too many function icons154, user interface140may become cluttered and difficult for users to use.

This problem can be addressed by selectively modifying the displayed content based on the interests of one or more users. For example, the relevant content may be identified by monitoring user activities (such as using or not using particular function icons154) while one or more users use the software application during one or more sessions (including one or more previous sessions and/or current sessions of the one or more users). As shown inFIG. 1E, which presents a drawing illustrating a user interface160that customizes displayed icons in user interface140(FIG. 1D), a subset of the groups152and/or the function icons154(when the user activates or clicks on a given group, such as group152-2) may be displayed based on the monitored user activities. A total number of groups152and/or function icons154in the user interface160may be limited to a pre-determined range of numbers (such as five or ten), thereby simplifying user interface160and enhancing user productivity and satisfaction with the software application.

User interface160may include icons162(or links) that allow the one or more users to access a remainder of the groups152and/or the function icons154in user interface140(FIG. 1D), as shown inFIG. 1F, which presents a drawing illustrating a user interface170. This user interface displays additional function icons172in addition to the function icons154displayed in user interface160(FIG. 1E) when icon162-1is activated. Additionally, the selective modification may be dynamically adapted over time based on subsequent user activities (including activating any of the icons162), thereby allowing computer systems200inFIG. 2 and 300inFIG. 3, which can be used to implement the selective modifying, to ‘learn’ which of the groups152and/or the function icons154in user interface140(FIG. 1D) are of interest to a given user at a particular time.

FIG. 2presents a block diagram illustrating a networked computer system200that customizes displayed content in a document. As noted previously, the document may include web pages (such as those associated with collaborative systems) and/or user interfaces of software applications. In the discussion that follows, a user interface for a software application is used as an illustrative example.

In computer system200, a user may use a software application, such as financial software, that is resident on computer210. Alternatively, the user may utilize a software-application tool that is embedded in a web page. This web page may be provided by server214via network212.

Note that the software-application tool may be a stand-alone application or a portion of another application (such as financial software that is resident on and/or that executes on server214). In an illustrative embodiment, the software-application tool is a software package written in: JavaScript™ (a trademark of Sun Microsystems, Inc.), e.g., the software-application tool includes programs or procedures containing JavaScript instructions, ECMAScript (the specification for which is published by the European Computer Manufacturers Association International), VBScript™ (a trademark of Microsoft, Inc.) or any other client-side scripting language. In other words, the embedded software-application tool may include programs or procedures containing. JavaScript, ECMAScript instructions, VBScript instructions, or instructions in another programming language suitable for rendering by a web browser or another client application on the computer210.

Over time, computer210(if the software application is resident on computer210) and/or server214(if the software application is implemented as a software-application tool) may monitor and aggregate a log of user activities. As noted previously, this log may include the activities of one or more users (on multiple computers, such as computer210), and the user activities may be associated with one or more software application (which may include the financial software).

Based on the monitored user activities, as well as other factors such as user preferences and/or a data rate of network212, server214may provide instructions to computer210(if the software application is resident on computer210) that customize the displayed content in a user interface for the software application. In particular, the displayed function icons, which are associated with features/functions of the software application, may be selectively filtered and/or modified. Thus, the total number of displayed function icons may be limited and/or function icons that are popular may be highlighted.

Alternatively, if the software application is implemented as a software-application tool, server214may provide a revised web page to computer210. This revised web page may include a version of the software-application tool with customized content, e.g., the displayed function icons, which are associated with features/functions of the software application, may be selectively filtered and/or modified.

Computer210and/or server214may continue to monitor user activity after the displayed content is selectively modified. In this way, computer system200can continue to ‘learn’ what portion of the content associated with the application software is relevant or of interest to users, and can revise or update the displayed content (such as the displayed function icons) as the user activity evolves or changes by providing additional instructions or another revised web page to computer210. For example, as noted previously, if the user repeatedly selects an icon that displays one or more additional function icons, these function icons may be added to the function icons displayed in the user interface for the software application (and other function icons that were displayed, but which were not regularly used, may be removed).

The log of user activities and financial information associated with the financial software (such as an account balance at bank216and/or an account history) for one or more users may be stored on server214and/or at one or more other locations in computer system200(i.e., locally or remotely). Moreover, because this information may be sensitive in nature, it may be encrypted. For example, stored information and/or information communicated via network212may be encrypted.

Computer210may be one of a variety of devices capable of manipulating computer-readable data or communicating such data between two or more computing systems over a network, including: a personal computer, a laptop computer, a portable electronic device (such as a cellular phone or PDA), and/or a client computer (in a client-server architecture). Moreover, network212may include: the Internet, World Wide Web (WWW), an intranet, LAN, WAN, MAN, or a combination of networks, or other technology enabling communication between computing systems.

Computer system200may include fewer components or additional components. Moreover, two or more components may be combined into a single component, and/or a position of one or more components may be changed.

FIG. 3presents a block diagram illustrating a computer system300that customizes displayed content in a document. Computer system300includes one or more processors310, a communication interface312, a user interface314, and one or more signal lines322coupling these components together. Note that the one or more processing units310may support parallel processing and/or multi-threaded operation, the communication interface312may have a persistent communication connection, and the one or more signal lines322may constitute a communication bus. Moreover, the user interface314may include: a display316, a keyboard318, and/or a pointer320, such as a mouse.

Memory324in the computer system300may include volatile memory and/or non-volatile memory. More specifically, memory324may include: ROM, RAM, EPROM, EEPROM, flash memory, one or more smart cards, one or more magnetic disc storage devices, and/or one or more optical storage devices. Memory324may store an operating system326that includes procedures (or a set of instructions) for handling various basic system services for performing hardware-dependent tasks. While not explicitly indicated in the computer system300, in some embodiments the operating system326includes a web browser. Memory324may also store procedures (or a set of instructions) in a communication module328. These communication procedures may be used for communicating with one or more computers and/or servers, including computers and/or servers that are remotely located with respect to the computer system300.

Memory324may also include multiple program modules (or a set of instructions), including: financial module330(or a set of instructions), monitoring/customizing module332(or a set of instructions), and/or optional encryption module348(or a set of instructions).

Monitoring/customizing module332may collect user activities in user-activity log338as one or more users view or interact with one or more documents334, such as document A336-1or document B336-2, during one or more sessions. Based on the user-activity log338, optional user profiles340, and/or weights342, monitoring/customizing module332may identify relevant content in documents334. Then, monitoring/customizing module332may selectively modify the displayed content in documents334. In some embodiments, the displayed content is selectively modified based on link characteristics352(such as a maximum data rate).

The selectively modified documents may include icons and/or links to a remainder of the original content that users can selectively activate. For example, these links may include links to additional documents350. Moreover, monitoring/customizing module332may continue to monitor subsequent user activities, which are stored in user-activity log338, and which allow monitoring/customizing module332to dynamically modify the displayed content as a function of time, thereby maintaining a relevance and ease of use of documents334.

In some embodiments, documents334are associated with financial module330. For example, documents334may include one or more web pages associated with financial module330. Moreover, using financial module330and one or more of documents334, users may modify financial information344, such as financial information for user A346-1or user B346-2.

In some embodiments, at least some of the information stored in memory324and/or at least some of the information communicated using communication module328is encrypted using optional encryption module348.

Instructions in the various modules in the memory324may be implemented in: a high-level procedural language, an object-oriented programming language, and/or in an assembly or machine language. Note that the programming language may be compiled or interpreted, e.g., configurable or configured, to be executed by the one or more processing units310.

Although the computer system300is illustrated as having a number of discrete items,FIG. 3is intended to be a functional description of the various features that may be present in the computer system300rather than a structural schematic of the embodiments described herein. In practice, and as recognized by those of ordinary skill in the art, the functions of the computer system300may be distributed over a large number of servers or computers, with various groups of the servers or computers performing particular subsets of the functions. In some embodiments, some or all of the functionality of the computer system300may be implemented in one or more application-specific integrated circuits (ASICs) and/or one or more digital signal processors (DSPs).

Computer system300may include fewer components or additional components. Moreover, two or more components may be combined into a single component, and/or a position of one or more components may be changed. For example, financial module330and monitoring/customizing module332may be combined into a single module. In some embodiments, the functionality of the computer system300may be implemented more in hardware and less in software, or less in hardware and more in software, as is known in the art.

We now discuss processes for customizing displayed content in a document.FIG. 4presents a flow chart illustrating a process400for customizing displayed content in a document, which may be performed by a computer system (such as computer system200inFIG. 2and/or computer system300inFIG. 3). During operation, the computer system monitors user activity while one or more users view a document during one or more sessions (410). Then, the computer system selectively modifies the displayed content in the document based on the monitored user activity (412).

If a given icon is activated by a given user (414), the computer system may display at least some of the remainder of the content in the document (416). Moreover, the computer system may optionally adjust the displayed content based on user activity after the selective modifying (418).

In some embodiments of process400, there may be additional or fewer operations. Moreover, the order of the operations may be changed, and/or two or more operations may be combined into a single operation.

We now discuss data structures that may be used in computer system200(FIG. 2) and/or300(FIG. 3).FIG. 5presents a block diagram illustrating a data structure500. This data structure may include content510for one or more documents. For example, content510-1for one or more documents may include: one or more document identifiers512-1, one or more locations514-1in the documents, corresponding content516-1at the one or more locations514-1, displayed content518-1, and links to related documents520-1.

FIG. 6presents a block diagram illustrating a data structure600. This data structure may include user activities610for one or more users. For example, user activities610-1may include: one or more user identifiers612-1, one or more sessions614-1, documents616-1, and/or user activities (including content that was accessed618-1or provided620-1).

Note that that in some embodiments of the data structures500(FIG. 5) and/or600there may be fewer or additional components. Moreover, two or more components may be combined into a single component, and/or a position of one or more components may be changed.
