The terms “a,” “an,” and “the” also refer to “one or more” unless expressly specified otherwise.
Furthermore, the described features, advantages, and characteristics of the embodiments may be combined in any suitable manner. One skilled in the relevant art will recognize that the embodiments may be practiced without one or more of the specific features or advantages of a particular embodiment. In other instances, additional features and advantages may be recognized in certain embodiments that may not be present in all embodiments.
These features and advantages of the embodiments will become more fully apparent from the following description and appended claims, or may be learned by the practice of embodiments as set forth hereinafter. As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method, and/or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module,” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.
Many of the functional units described in this specification have been labeled as modules, in order to more particularly emphasize their implementation independence. For example, a module may be implemented as a hardware circuit comprising custom VLSI circuits or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. A module may also be implemented in programmable hardware devices such as field programmable gate arrays, programmable array logic, programmable logic devices or the like.
Modules may also be implemented in software for execution by various types of processors. An identified module of computer readable program code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be organized as an object, procedure, or function. Nevertheless, the executables of an identified module need not be physically located together, but may comprise disparate instructions stored in different locations which, when joined logically together, comprise the module and achieve the stated purpose for the module.
Indeed, a module of computer readable program code may be a single instruction, or many instructions, and may even be distributed over several different code segments, among different programs, and across several memory devices. Similarly, operational data may be identified and illustrated herein within modules, and may be embodied in any suitable form and organized within any suitable type of data structure. The operational data may be collected as a single data set, or may be distributed over different locations including over different storage devices, and may exist, at least partially, merely as electronic signals on a system or network. Where a module or portions of a module are implemented in software, the computer readable program code may be stored and/or propagated on in one or more computer readable medium(s).

In one embodiment, a category may include one or more subcategories. The subcategories may be defined by the user. Alternatively, the subcategories may be predefined for the category database 260.
The recording module 220 may record 510 a navigation action 120 directed to first content 105 of the content stream 100. For example, the recording module 220 may record 510 a content like navigation action 120 directed the first content 105. Alternatively, the recording module 220 may record 510 a navigation action 120 that is intuited from user behavior. For example, if the user pauses while scrolling through a list of content 105, the recording module 220 may record 510 a scroll pause navigation action 124 for all content that is visible to the user during the scroll pause.
In one embodiment, the navigation actions 120 are recorded in the navigation database 265. The navigation database 265 may include an entry for all categories. Alternatively the navigation database 265 may have an entry for all content 105. The navigation database 265 may record a number and type of navigation actions 120 associated with the category and/or content. The navigation database 265 may also include a timestamp for each navigation action 120. Navigation actions 120 may be deleted from the navigation database 265 after a retention and interval.
In one embodiment, the recording module 220 elevates 515 a ranking of a first category associated with the first content 105 in response to the navigation action 120. For example, if a content comment navigation action 120 is directed to the first content 105, the recording module 220 elevates 515 the ranking of the first category that is associated to the first content 105.
In a certain embodiment, the ranking of a category is elevated 515 using Equations 1 or 2, where R is the ranking, v is a value of a navigation action 120, and t is a time interval since the navigation action 120 occurred.

R=Σv/t   Equation 1

R=Σv/t2   Equation 2

Thus each time a navigation action 120 is recorded 510 for content 105 that is associated with the category, the ranking of the category may be elevated 515. The categories may thus be ranked in the sequence of the ranking values. Alternatively, each hierarchal level may be associated with a ranking range. The recording module 220 may assign each category to a hierarchical level based on the ranking of the category.
In one embodiment, each type of navigation action 120 is associated with the unique value v. A content upload navigation action 120 may have a higher value than a scroll cause navigation action 120. Table 1 lists exemplary values for navigation actions

The recording module 225 may display 520 the highest-ranking categories. In one embodiment, the highest-ranking categories are displayed 520 for selection. The highest-ranking categories may be displayed as a combo box, a drop-down menu, selection buttons, radio buttons, or the like.
In one embodiment, the displayed highest-ranking categories are sorted. The displayed highest ranking categories may be sorted based on a criteria selected from the group consisting of the ranking value of each category, category preferences, alphabetizing, cumulative navigation action strength, temporal weight, and an affinity weight to user friends.
For example, the category with the highest-ranking value may be displayed first, followed sequentially by categories with lower ranking values. Alternatively, the user may select the category preferences. For example, the user may specify that a first category has preference over a second category.
In one embodiment, the categories are sorted alphabetically. Alternatively, the categories may be sorted by a cumulative navigation action strength. The cumulative navigation action strength for a category may be calculated using Equation 3, where S is the cumulative navigation action strength, v is the navigation action value of each navigation action 120 directed to content 105 associated with the category, and n is a number of navigation actions 120.

S=(Σv)/n   Equation 3

in one embodiment, the temporal weight is calculated using Equation 4, where W is the temporal weight and t is the time interval since a last navigation action 120 occurred for content 105 associated with the category.

W =1/t   Equation 4

In one embodiment, all subcategories of the category are displayed. Alternatively, only subcategories with rankings that exceed a ranking threshold are displayed.
In one embodiment, the recording module 225 receives 525 a selection of the displayed categories. The selection may be a user selection. For example, a user may select a category from a drop-down menu.
The recording module 225 may perform 530 a content action on content 105 in the selected category in response to the category selection and the method 500 ends. In one embodiment, the content action is displaying the content 105 of the selected category. Alternatively, the content action may share the content of the selected category with a second user.
FIG. 5 is a drawing illustrating one embodiment of displayed categories 125. The browser 110 of FIG. 1 is shown displaying the content stream 100 of FIG. 1. Categories 125 are also displayed 520 in a menu. The categories 125 may be displayed 520 in response to the users selecting a category icon 130.
The user may select a category 125 from the menu. The recording module 225 receives 525 the selection and performs a content action in response to the category selection.
FIG. 6 is a drawing illustrating one embodiment of displayed content 105. The browser 110 of FIG. 5 is shown displaying selected content 105 in response to a selection of a category 125. For example, the depicted selected content 105 may be displayed in response to the users selecting the “jobs” category in FIG. 5.
By elevating the ranking of categories 125 in response to navigation actions 120, the embodiments described herein display the categories 125 that are likely of most interest to the user. As a result, the user may more easily and quickly navigate to content 105 of interest in the content stream 100.
The embodiments may be practiced in other specific forms. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
