## Title
Automatically granting access to content in a microblog

## Abstract

A method, system and computer program product for automatically granting access to content referenced in a microblog. A microblog post having content referenced therein is received by a microblog server. The microblog post includes a special character (e.g., “@”) designating a user, group or community. Furthermore, the microblog post includes a special character (e.g., “!”) designating the content. In response to recognizing the special character designating the content, the microblog server grants access to the designated content to the user, group or community referenced in the microblog post. By including a special character in the microblog post to designate content to be made available to the user, group or community referenced in the microblog post, the user can now designate the content to be made available to the users, groups and/or communities that do not previously have rights to access the content in an easy and efficient manner.

## Background
TECHNICAL FIELD
The present invention relates generally to microblogging services, and more particularly to automatically granting access to content (e.g., files) referenced in a microblog to persons, groups and/or communities referenced in the microblog.
BACKGROUND
Microblogging is a broadcast medium in the form of blogging. A microblog differs from a traditional blog in that its content is typically smaller in both actual and aggregate file size. Microblogs allow users to exchange small elements of content, such as short sentences, individual images, or video links, to people who are subscribed to their posts or within their community. These small messages are sometimes called microposts.
In order to assist users to find microblog messages that are relevant to them, some social networking and microblogging tools support the use of hashtags and “@mentions.” Hashtags are words or phrases prefixed with the symbol “#” to indicate a topic of interest. A “mention” is a means by which a blog post references or links to a user, group or community, such as by identifying the user, group or community following the symbol “@.”
While existing microblogging tools use these special characters (e.g., “#,” “@”) to attract attention, they do not provide a way to guarantee access to the content (e.g., file) referenced in the microblog post to the users or groups or communities that are referenced in the microblog post. Currently, users wishing to share content referenced in the microblog post to particular users that do not currently have access to the content need to add these users to the groups or communities referenced in the microblog post prior to sending the microblog post. Additionally, if a user wishes to mention a person in a microblog post but that user is not yet a member of the group or community referenced in the microblog post, the user would not be able to receive the notification of the microblog post, let alone have access to the content referenced in the microblog post. As a result, there is not currently an efficient process for the user to allow users, groups or communities to have access to the content referenced in a microblog post for those users, groups or communities that do not previously have rights to access the content, despite being referenced in the microblog post.
BRIEF SUMMARY
In one embodiment of the present invention, a method for automatically granting access to content referenced in a microblog comprises receiving a microblog post having content referenced therein, where the microblog post comprises a first character designating a user, a group or a community, and where the microblog post comprises a second character designating the content. The method further comprises recognizing the first character and the second character in the microblog post. Additionally, the method comprises notifying the user, the group or the community designated in the microblog post of the microblog post in response to recognizing the first character in the microblog post. In addition, the method comprises granting, by a processor, access to the designated content to the user, the group or the community designated in the microblog post in response to recognizing the second character in the microblog post.
Other forms of the embodiment of the method described above are in a system and in a computer program product.
The foregoing has outlined rather generally the features and technical advantages of one or more embodiments of the present invention in order that the detailed description of the present invention that follows may be better understood. Additional features and advantages of the present invention will be described hereinafter which may form the subject of the claims of the present invention.

DETAILED DESCRIPTION
The present invention comprises a method, system and computer program product for automatically granting access to content referenced in a microblog. In one embodiment of the present invention, a microblog post having content (e.g., file) referenced therein is received by a microblog server. The microblog post includes a special character (e.g., “@”) designating a user, group or community. Furthermore, the microblog post includes a special character (e.g., “!”) designating the content. In response to recognizing the special character (e.g., “!”) designating the content, the microblog grants access to the designated content to the user, group or community designated in the microblog post. By including a special character, such as “!”, in the microblog post to designate content to be made available to the user, group or community referenced in the microblog post, the user can now designate the content to be made available to the users, groups and/or communities that do not previously have rights to access the content in an easy and efficient manner.
In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced without such specific details. In other instances, well-known circuits have been shown in block diagram form in order not to obscure the present invention in unnecessary detail. For the most part, details considering timing considerations and the like have been omitted inasmuch as such details are not necessary to obtain a complete understanding of the present invention and are within the skills of persons of ordinary skill in the relevant art.
Referring now to the Figures in detail, FIG. 1 illustrates a microblogging system 100 configured in accordance with an embodiment of the present invention. Referring to FIG. 1, social network system 100 includes a community of users using client devices 101A-101C (identified as “Client Device A,” “Client Device B,” and “Client Device C,” respectively, in FIG. 1) to be involved in microblogging system 100.

As stated in the Background section, while existing microblogging tools use these special characters (e.g., “#,” “@”) to attract attention, they do not provide a way to guarantee access to the content (e.g., file) referenced in the microblog post to the users or groups or communities that are referenced in the microblog post. Currently, users wishing to share content referenced in the microblog post to particular users that do not currently have access to the content need to add these users to the groups or communities referenced in the microblog post prior to sending the microblog post. Additionally, if a user wishes to mention a person in a microblog post but that user is not yet a member of the group or community referenced in the microblog post, the user would not be able to receive the notification of the microblog post, let alone have access to the content referenced in the microblog post. As a result, there is not currently an efficient process for the user to allow users, groups or communities to have access to the content referenced in a microblog post for those users, groups or communities that do not previously have rights to access the content, despite being referenced in the microblog post.
The principles of the present invention provide a means for automatically granting access to content referenced in a microblog to all the users, groups and/or communities designated in the microblog (even those users, groups and communities that do not previously have rights to access the content) through the use of a special character (e.g., “!”) designating the content as discussed further below in association with FIG. 3.
FIG. 3 is a flowchart of a method 300 for automatically granting access to content referenced in a microblog to all the users, groups and/or communities designated in the microblog through the use of a special character (e.g., “!”) designating the content in accordance with an embodiment of the present invention.
Referring to FIG. 3, in conjunction with FIGS. 1-2, in step 301, microblog server 103 receives a microblog post having content (e.g., file) referenced therein, where the microblog post includes a special character (e.g., “@”) designating a user, group or community and a special character (e.g., “!”) designating the content. For example, the microblog post of “@JohnSmith please review the !QuarterlyReport draft file” designates John Smith to be notified regarding the QuarterlyReport draft file via the “@” character. Furthermore, the “!” character is used to indicate that John Smith is to have access to the Quarterly Report file. By including a special character, such as “!”, in the microblog post to designate content to be made available to the users, groups and/or communities referenced in the microblog post, the user can now designate the content to be made available to the users, groups and/or communities that do not previously have rights to access the content in an easy and efficient manner. It is noted that the principles of the present invention are not limited to the use of the “!” character to designate the content to be made available to the users, groups and/or communities referenced in the microblog post but to include any type of character, user interface affordances, keyboard shortcuts, gestures, etc.
In one embodiment, when the user of client device 101 enters the special character (e.g., “!”) to designate content, the user interface may launch a selection menu thereby allowing the user to select the content (e.g., files) to be inserted in the microblog post in response to entering the special character.
In one embodiment, when the designated content is restricted, another special character (e.g., “^”) may be used in the microblog post to grant access to the restricted content on a local device, such as the local device of a user referenced in the microblog post. It is noted that the principles of the present invention are not limited to the use of the “^” character to grant access to restricted content on a local device but to include any type of character, user interface affordances, keyboard shortcuts, gestures, etc.
In step 302, microblog server 103 recognizes the special character (e.g., “@”) in the microblog post designating the user, group or community and recognizes the special character (e.g., “!”) in the microblog post designating the content. In one embodiment, the special character (e.g., “@”) designates the user, group or community that is adjacent to the special character in the microblog post (e.g., “@JohnSmith”). In one embodiment, the special character (e.g., “!”) designates the content that is adjacent to the special character in the microblog post (e.g., “!QuarterlyReport draft file”). In one embodiment, microblog server 103 recognizes a special character (e.g., “^”) in the microblog post that grants access to restricted content on a local device.
In step 303, microblog server 103 notifies the user, group or community designated in the microblog post of the microblog post in response to recognizing the special character (e.g., “@”) designating the user, group or community. Referring to the above example, microblog server 103 notifies John Smith about the microblog post referencing the QuarterlyReport draft file.
In step 304, microblog server 103 grants access to the designated content to the user, group or community designated in the microblog post in response to recognizing the special character (e.g., “!”) designating the content. In one embodiment, the designated content is accessible online. In one embodiment, microblog server 103 grants access to the designated content to the user, group or community designated in the microblog post by adding the user, group or community designated in the microblog post that did not previously have rights to access the content to an access control list for the designated content. In this manner, the users who did not previously have access to the designated content will now have access to the designated content. Users, groups and communities that previously had rights to access the content may not need to be added to the access control list for the designated content since they would already be listed.
Optionally, in step 305, microblog server 103 provisions the designated content to the user, group or community designated in the microblog post for offline access. In one embodiment, when the content is restricted, the restricted content is accessible offline, such as on a local device, in response to the use of a special character (e.g., “^”) in the microblog post granting access to the restricted content on the local device.
Furthermore, optionally, in step 306, microblog server 103 generates a task to the user, group or community designated in the microblog post to review the designated content.
In some implementations, method 300 may include other and/or additional steps that, for clarity, are not depicted. Further, in some implementations, method 300 may be executed in a different order presented and that the order presented in the discussion of FIG. 3 is illustrative. Additionally, in some implementations, certain steps in method 300 may be executed in a substantially simultaneous manner or may be omitted.
The descriptions of the various embodiments of the present invention have 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.
