Aspects of the present invention relate to monitoring and managing updates to content, and more particularly to a method, system and computer program product for content following content for providing updates to content that is leveraged or used in a deck.
There is a need or desire by users for keeping up to date on content that is being created in a system or network by other users. To address this need or desire, communications software products, such as social software products, offer the concept of following. Following enables a user to indicate an interest in certain pieces of content available in the system or network where the user wants the system to bring changes in those pieces of content to the attention of the user. Attention management has taken different forms ranging from sending emails to the user to presenting activity streams directed to the user, and even as far as being able to take action on the changes by the user from within an embedded experience in an activity stream, enabling the user to keep context and absorb and take action on changes to content. Accordingly, while the concept of a user following a piece of content may be implemented, a problem that is not addressed is content following content. Currently, the user has to follow the necessary pieces of content and then the user must stitch or assemble together the relevant updates and create a package of these updates that may relate to some content that the user may have created. For example, a user may create a document or presentation for a particular audience. The document or presentation may use material from existing content from other sources that may be modified for the intended audience. The material may leverage or use content or pieces of content from other documents or presentations. Traditionally, the user or author reviews the other documents or asks the relevant people for input and puts together the document. Over time, the supporting content or pieces of content that were used to create the document may change and the author or user may need to revise or redo the original document.
According to one embodiment of the present invention, a method for providing updates for pieces of content in a deck may include creating, by a processor, a deck. The deck may include a plurality of pieces of content. The method may also include leveraging, by the processor, a part of existing content, existing before creation of the deck, for at least one of the plurality of pieces of content in the deck. The at least one of the plurality of pieces of content in the deck that leverages the part of existing content is leveraged content and the part of the existing content is referenced content. The method may additionally include configuring, by the processor, the leveraged content for following the referenced content or ancillary content of the referenced content to obtain updates or notifications of updates to the referenced content or ancillary content. Therefore, an advantage of the method is that leveraged pieces of content in the deck are configured for following the parts of referenced content or ancillary content on a system or available through a communications network for providing updates for the leveraged content in the deck. Another advantage of embodiments of the present invention of the leveraged content following the referenced content is that the user does not have to take any action to indicate an interest in particular content or pieces of content as would be the case with the user following content.
According to another embodiment of the present invention, a system for providing updates for pieces of content in deck may include a processor and a module operating on the processor for providing updates for pieces of content in deck. The module may be configured to perform a set of functions including creating a deck. The deck may include a plurality of pieces of content. The set of functions may also include leveraging a part of existing content, existing before creation of the deck, for at least one of the plurality of pieces of content in the deck. The at least one of the plurality of pieces of content in the deck that leverages the part of existing content may be defined as leveraged content and the part of the existing content may be defined as referenced content. The set of functions may additionally include configuring the leveraged content for following the referenced content or ancillary content of the referenced content to obtain updates or notifications of updates to the referenced content or ancillary content. At least one advantage of the system is that leveraged pieces of content in the deck are configured for following the parts of referenced content or ancillary content for providing updates for the leveraged content in the deck.
According to another embodiment of the present invention, a computer program product for providing updates for pieces of content in deck may include a computer readable storage medium having program instructions embodied therewith. The computer readable storage medium is not a transitory medium per se, the program instructions may be executable by a device to cause the device to perform a method that may include creating a deck. The deck may include a plurality of pieces of content. The method may also include leveraging a part of existing content, existing before creation of the deck, for at least one of the plurality of pieces of content in the deck. The at least one of the plurality of pieces of content in the deck that leverages the part of existing content may define leveraged content and the part of the existing content may define referenced content. The method may additionally include configuring the leveraged content for following the referenced content or ancillary content of the referenced content to obtain updates or notifications of updates to the referenced content or ancillary content. An advantage of the computer program product is that leveraged pieces of content in the deck are configured for following the parts of referenced content or ancillary content on a system or available through a communications network for providing updates for the leveraged content in the deck.
In some other embodiments of the present invention and in combination with any of the above embodiments, the leveraged content being configured to follow the referenced content or ancillary content may include subscribing the leveraged content to receive updates or notifications of updates to the referenced content or ancillary content. Updates to the referenced content or ancillary content may be detected by the system or process method and the updates or notifications of updates may be automatically transmitted to the leveraged content. The updates or notifications of updates may be stored in a memory in association with the leveraged content. An advantage of these features is that the leveraged content may then automatically receive updates or notifications of updates to the referenced content or ancillary content and the updates or notifications are stored in association with the leveraged content to facilitate access by the user and use by the user in updating the deck.
In some other embodiments of the present invention and in combination with any of the above embodiments, the leveraged content configured to follow the referenced content or ancillary content may include the leveraged content being configured or transformed to periodically transmit a request to the corresponding referenced content for any updates. The updates may then be transmitted to the leveraged content and stored in a memory in association with the leveraged content to facilitate access and use by the user in revising the deck.
In some other embodiments of the present invention and in combination with any of the above embodiments, an integrated contextual activity stream may be created. The integrated contextual activity stream may include a list of updates or notifications of updates to the referenced content or ancillary content. The integrated contextual activity stream may be presented to the user in response to a predetermined action or event. The list of updates or notification of updates may be in a particular order or ranking. For example, the updates or notifications of updates may be in chronological order, either from most recent to oldest or oldest to most recent. In another embodiment, the updates or notifications of updates may also be in order of importance based on a predetermined criterion, such as subject matter of the update or other criteria. One advantage of these features is that a user can view a history or sequence of updates or notifications of updates to the referenced content. The user may edit the leveraged content in the deck based on the updates or notifications of updates to the corresponding referenced content, or the user may select which updates to the referenced content may be used to revise the corresponding leveraged content in the deck.

One or more parts of existing content available in a system or network may be leveraged or used by a user or author of the deck for one or more of the pieces of content in the deck. The existing content is content that is available at the time of creation of the deck or any revisions to the deck at a later time. The one or more pieces of content in the deck that are leveraged by existing content available in the system or network may be defined herein as leveraged content. The one or more parts of existing content available in the system or network that are used to leverage content in the deck may be defined herein as referenced content. The leveraged content or pieces of leveraged content may correspond to or may be the same as the referenced content or respective parts of referenced content, or the leveraged content or pieces of leveraged content may be derived from the referenced content. The leveraged content may also correspond to ancillary content of the referenced content. An example of ancillary content may be content that is not the original referenced content.
The referenced content or parts of referenced content that may be used to leverage the leveraged content or pieces of leveraged content in the deck may include but is not necessarily limited to files, documents, presentations, blogs, wikis, forums, web pages, other decks or other works. The referenced content may have been created by other members or users of the system or network and/or the author of the deck being created or revised. The system or network may be a public system or network, such as the Internet or a private or proprietary system or network, such as an intranet. The network may be or may include a social network or other communications network in which the user or author is a member or participant.
In block 104, a mechanism to access each part of referenced content or ancillary content may be associated with the corresponding piece of leveraged content used in the deck. In some embodiments, a link may be associated with each piece of leveraged content that provides access to the corresponding part of referenced content or ancillary content. The link may be a uniform resource locator (URL) or other mechanism for accessing the referenced content or ancillary content from the corresponding leveraged content in the deck.
In accordance with an embodiment, selected pieces of leveraged content may be linked to corresponding parts of referenced content. For example, a user or author of the deck may consider that some leveraged content or pieces of leverage content do not need to be linked to the corresponding referenced content or ancillary content because the leveraged content may not need to be updated in response to changes in the referenced content or ancillary content for certain reasons. In other embodiments, each piece of leveraged content may be linked to the corresponding part of the referenced content or ancillary content. An advantage to this feature is that the user or author may then determine at a later time whether to actually update the particular piece of leveraged content with corresponding updated part of the referenced content or ancillary content.
In block 106, the deck may be stored in a memory associated with a computing device of the user or author of the deck. The link or mechanism for accessing a particular part of referenced content may also be stored in association with the corresponding piece of leveraged content in the deck.
In block 108, the deck may be published. In accordance with an embodiment, the deck may be published by making the deck available for access by any user or by chosen users in the system or communications network. For example, the deck may only be made available for participants or members of a particular communications network, social network, or a select group of users. In accordance with another embodiment, the deck may be published by actually transmitting the deck to chosen users or subscribers. In a further embodiment, the deck may be published by transmitting a notification of availability of the deck to chosen users or subscribers. The users or subscribers may then access the deck in response to the notification.
In block 110, each piece of content in the deck may be converted to plain text. This may include leveraged pieces of content and content that is not leveraged or content in the deck that does not make reference or use parts of existing content available in the system or on the network. The content may be converted to plain text by using a word recognition program or other software capable of scanning the pieces of content in the deck and converting the content to plain text.
In block 112, the link or mechanism for accessing the parts of the referenced content or ancillary content may be extracted from the corresponding pieces of leveraged content in the deck. As previously discussed, in some embodiments, selected pieces of the leveraged content may be linked to the corresponding part of referenced content or ancillary content on the system or network. In other embodiments, each piece of leveraged content may be linked to the corresponding part of referenced content or ancillary content to preserve the user's ability to selectively update any of the leveraged content in response to the corresponding part of referenced content or ancillary content being changed.
In block 114, the pieces of leveraged content may be configured for following the corresponding parts of referenced content or ancillary content to obtain updates or notifications of updates to the corresponding referenced content, parts of referenced content or ancillary content. The updates or notifications of updates are received by the respective pieces of leveraged content that correspond to each of the parts of referenced content or ancillary content. The updates or notifications of updates to the referenced content or ancillary content may be stored in a memory of the user's computer device in association with the corresponding piece of leveraged content or in another storage device on the system or network. In accordance with one or more embodiments, an integrated contextual activity stream may be created and associated with each piece of leveraged content that includes the updates or notifications of updates to the referenced content or ancillary content that corresponds to each piece of leveraged content. The integrated contextual activity stream may be stored in the memory of the user's computer device or in another storage device on the system or network. Embodiments of the invention in which the leveraged content is configured for following the referenced content rather than the user or author of the deck saves the user from the burden of personally having to follow multiple different parts of content that may be located at various locations in a system or on a network. Additionally, embodiments in which the updates or notifications of updates are used to create an integrated contextual activity stream avoids the user or author of the deck from having to stitch together or assemble the relevant updates and create a package of these updates that may relate to the leveraged content or some content that the user has created.
The leveraged content following the referenced content being used to obtain updates or notification of updated to the corresponding referenced content or ancillary content in block 114 may involve different operations or functions as described with reference to blocks 116-122 that may or may not be included in different embodiments.
In block 116, in accordance with one or more embodiments of the invention, the leveraged content following the referenced content may include the leveraged content automatically subscribing to receive updates or notifications of updates to the corresponding referenced content or ancillary content using the mechanism or link for accessing the referenced content or ancillary content. Each piece of leveraged content may subscribe to the corresponding part of the referenced content for receiving updates or notifications of updates or in other embodiments selected pieces of leveraged content may subscribe to the corresponding parts of the referenced content. Under some circumstances, the leveraged content may subscribe to ancillary content of the referenced content. The ancillary content may be material or content other than the original material or content available in the system or accessible over the communications network. For example, ancillary content may include but is not necessarily limited to comments related to the referenced content or other materials. The leveraged content or piece of leveraged content will then receive updates or notifications of updates to the corresponding part of the referenced content or ancillary content to which the leveraged content is subscribed. Updates to the referenced content or ancillary content may be detected by a detection module associated with the system and the detection module may instruct the referenced content to transmit the update or a notification of the update to the subscribing leveraged content or piece of leveraged content, or in other embodiments, the detection module or system may transmit the update or notification of update to the subscribing leveraged content. Embodiments of the invention in which the leveraged content is configured for following the referenced content by the leveraged content subscribing to updates to the reference data or ancillary data has the advantage of automatically providing updates to the user or author without the user having to perform any action or having to manually follow different content on the system or network.
In accordance with another embodiment, the leveraged content or piece or leveraged content may be modified to include a code segment that may generate and transmit a query at preset time intervals to the corresponding referenced content or part of referenced content or ancillary content to determine if the referenced content or ancillary content may have been updated. If the referenced content or ancillary content has been updated, the system may retrieve and transmit the update from the referenced content or ancillary content to the leveraged content or piece of leveraged content. In other embodiments, the referenced content or ancillary content that has been updated may be instructed to transmit the update or notification of the update to the corresponding leveraged content or piece of leveraged content. The update may then be stored in the memory in association with the leveraged content similar to that previously described. An integrated contextual activity stream may be created using the updates and associated with the particular leveraged content. The preset time interval for generating and transmitting the query may be adjusted by the user. The preset time interval may set according to an expected frequency of updates to the particular referenced content. For example, the preset time interval may be each day, after a preset number of days, etc.
In block 118, in accordance with some embodiments, the pieces of leveraged content in the deck that are following corresponding referenced content or parts of referenced content on the system or network for receiving updates or notifications of updates may be identified in the deck. The pieces of leveraged content that are following referenced content may be identified by a special marking in the deck. Accordingly, the pieces of leveraged content that are following referenced content are apparent to the user when the deck is viewed. The identification or marking may only be viewable by the author or in other embodiments may be viewed by any user or only those users authorized to view the identification or marking of the pieces of leveraged content following referenced content. Embodiments of the invention that include the feature of marking or identifying leveraged content in the deck have the advantage of facilitating viewing or selectively viewing the updates or integrated contextual activity stream that may have been created using the updates or notifications of updates for a particular piece of leveraged content. The user may selectively operate a feature associated with the particular piece of leveraged content for viewing the updates or integrated contextual activity stream.
In block 120, updates or notifications of updates to the referenced content or parts of referenced content may be received by the corresponding leveraged content in the deck in response to the leveraged content being configured to follow the referenced content or the leveraged content being subscribed to the referenced content. The updates or notifications of updates may be stored in a memory in association with the corresponding leveraged content.
In block 122, as previously discussed, an integrated contextual activity stream may be created for each piece of leveraged content that receives updates or notifications of updates from corresponding referenced content or part of referenced content. The integrated contextual activity stream may be stored in association with the associated leveraged content or piece of leveraged content in a memory on the system or on a computer device associated with the user. Embodiments of the invention that include the feature of creating an integrated contextual activity stream and storing the activity stream in association with the associated piece of leveraged content in the deck have the advantage of assembling the relevant updates or notifications of updates and providing a package of these updates or notifications that the user can utilize to easily and efficiently update the leveraged content in the deck. For example, the user or author may simply cut and paste the updates from the integrated contextual activity stream to the leveraged content in the deck and then perform any editing in the deck.
In block 124, the updates or notifications of updates to the referenced content or part of referenced content or ancillary content corresponding to a particular piece of leveraged content may be presented on a display of a computer device. The updates or notifications of updates may be presented automatically in response to presenting the deck in accordance with one or more embodiments. In another embodiment, the updates or notifications of updates may be presented in response to activating a particular feature associated with the leveraged content or piece of leveraged content.
In accordance with one or more embodiments, the integrated contextual activity stream may be presented containing the updates or notifications of updates. The integrated contextual activity stream may be presented automatically in response to presenting the deck or in response to activating a particular feature associated with the leveraged content or piece of leveraged content. The integrated contextual activity stream may include a list of updates or notifications of updates to the referenced content or ancillary content. The list of updates or notifications of updates may be in a particular order or ranking. For example, the updates or notifications of updates may be in chronological order, either from most recent to oldest or from oldest to most recent. In another embodiment, the updates or notifications of updates may also be listed in order of importance based on a predetermined criterion, such as subject matter of the update or other criteria. The integrated contextual activity stream may include a feature or mechanism for re-use or application of the updates in the deck. One advantage of these features is that a user can view a history or sequence of updates or notifications of updates to the referenced content. The user may edit the leveraged content in the deck based on the updates or notifications of updates to the corresponding referenced content, and/or the user may select which updates to the referenced content may be used to revise the corresponding leveraged content in the deck.
