Management of content items

Disclosed are various embodiments of a content management application that facilitates a content management system. Content items that can include audio and/or video can be stored in the content management system. A transcript is generated that corresponds to spoken words within the content. Content can be tagged based upon the transcript. Content anomalies can also be detected as well as editing functionality provided.

BACKGROUND

Content management systems can be utilized to organize, manage, and/or distribute content to various users for various purposes. For example, in a learning environment, users can access content provided by a content management system through various types of user interfaces. For example, the content management system can house and manage content that served up to clients via a network by a web server that retrieves content from the content management system. The content managed by a content management system can comprise, for example, learning content that is arranged into various learning units. Content can also comprise, for example, content associated with an electronic commerce site (e.g., product information) that is placed in web pages and transmitted to a client device. Accordingly, updating of content, particularly multimedia content items, can present a challenge, particular for large and diverse content sets.

DETAILED DESCRIPTION

Embodiments of the present disclosure are related to content management systems that can manage various types of content, including video, audio, imagery, documents, other binary file types, and/or other content. For example, a content management system can comprise a learning content management system that manages content for the purposes of learning and/or training. A learning content management system can maintain various learning units, which can include various types of content arranged into various chapters, hierarchies, nodes, or other arrangements that a user may access.

A content management system according to the present disclosure can house and/or manage content that can be accessed in various ways. In some embodiments, the content management system can render a user interface that is accessible via a network that allows users to view content accessible via the content management system. In other embodiments, content accessible via the content management system can be accessed via another system, such as an application that assembles dynamically generated web pages or other forms of content that are in turn sent to a requesting client device via a network.

Accordingly, when content managed by a content management system includes video content, audio content, imagery, documents in proprietary binary form, or other formats, updating content can present management challenges. For example, in an enterprise environment, look and feel guidelines may exist that specify guidelines regarding content that is published in a content management system. As these guidelines are changed over time, identifying conformance of content housed by the content management system to these guidelines can offer a challenge. Additionally, as another example, the names of products or services or other terminology associated with content can change over time. Therefore, assuring that content housed by the content management system is up to date, particularly where audio and/or video content is employed, is yet another logistical challenge. Additionally, where multimedia content is employed in the content management system, the content management system, according to an embodiment of the disclosure, can identify audio and/or video anomalies that can be flagged, potentially removed, and/or otherwise edited in order to improve the quality of content housed in the content management system.

Therefore, with reference toFIG. 1, shown is an example of a user interface100that can be generated by a content management system according to an embodiment of the disclosure. In the depicted example, a user interface that allows an administrative user to access content managed by the content management system is shown. In this introductory example, the user interface depicts an example of a content item stored in a content management system, which in this case is video content. The content item can be viewed by an administrative user to identify potential content anomalies, such as one or more audio anomalies.

In the example shown inFIG. 1, the content management system can identify as well as highlight potential audio anomalies to an administrative user. In the case ofFIG. 1, these anomalies can comprise verbal anomalies or spoken word anomalies. For example, content management systems can analyze a content item to identify interjections, utterances, mumblings, or sounds identified in the content item that may be potentially distracting to the user. The content management system can also provide the ability within the user interface100for the user to edit the content item to remove and/or otherwise edit the content item to eliminate and/or reduce the impact of the detected audio anomalies. As shown in the depicted introductory example ofFIG. 1, the content management system, according to an embodiment of the disclosure, can identify potential content anomalies to an administrative user and provide a playback interface so that these anomalies can be reviewed by a user. Additionally, the content management system can also provide video and/or audio editing functionality so that the user can address the content anomalies by removing content from the content item and/or making other types of adjustments. Other examples of functionality of a content management system according to embodiments of the disclosure are shown and discussed herein.

With reference toFIG. 2, shown is a networked environment200according to various embodiments. The networked environment200includes a computing environment203and at least one data consumer206, which are in data communication with each other via a network209. The network209may include, for example, the Internet, intranets, extranets, wide area networks (WANs), local area networks (LANs), wired networks, wireless networks, or other suitable networks, etc., or any combination of two or more such networks.

Various applications and/or other functionality may be executed in the computing environment203according to various embodiments. Also, various data is stored in a data store212that is accessible to the computing environment203. The data store212may be representative of a plurality of data stores212as can be appreciated. The data stored in the data store212, for example, is associated with the operation of the various applications and/or functional entities described below.

The components executed on the computing environment203, for example, include a content management application215and other applications, services, processes, systems, engines, or functionality not discussed in detail herein. The content management application215provides the functionality of a content management system. For example, the content management application215can provide user interfaces through which content managed by the content management system can be accessed, managed, edited, or otherwise manipulated by administrative users. The content management application215can also provide one or more interfaces (e.g., a web services application programming interface) through which content can be accessed by other systems for presentation to users consuming content that is managed by the content management system. For example, a system charged with assembling dynamically generated web pages from content housed within the content management system can access content via a web services API provided by the content management application215.

For example, the content management application215may communicate with a data consumer206over various protocols such as, for example, hypertext transfer protocol (HTTP), simple object access protocol (SOAP), representational state transfer (REST), real-time transport protocol (RTP), real time streaming protocol (RTSP), real time messaging protocol (RTMP), user datagram protocol (UDP), transmission control protocol (TCP), and/or other protocols for communicating data over the network209in order to provide content that is housed within the content management system.

The data stored within the data store212includes, for example, content items221, which are associated with a content type231as well as meta data233and a content hierarchy223. Content items221represent audio content, video content, imagery, documents, text, or any type of content that can be housed in a content management system. For example, in the case of a learning content management system, content items221can represent training materials, such as videos, slide presentations, documents, or other training collateral that can be associated with a training topic or training module. Content items221can also represent documents in open and/or proprietary formats that contain textual content, embedded imagery, video, audio, and/or any other forms of content.

To this end, content items221can be tagged with a content type231that specifies a content type of the content item221. Additionally, content items221can also be associated with meta data233that is generated by the content management application215to facilitate embodiments of the disclosure. Meta data233can include one or more descriptive tags that are automatically and/or manually generated and associated with a content item221. Meta data233can also include a transcript of spoken words that are contained with the content item221that can be generated by the content management application215. Meta data233can include any other information about a content item221that can be utilized by the content management application215to manage content in the content management system.

The data store212can also store content hierarchy223data that describes how the various content items221are arranged with relation to one another. The content hierarchy223can describe a hierarchical structure where certain content items221are nodes in a tree-like structure. It should also be appreciated that content items221need not be arranged in a hierarchy. For example, the various content items221can simply be stored along with meta data233in the data store212, and the content management application215can locate content items221in the data store212via tags that are stored in the meta data233, an index of content items221stored in the data store212or any other method of organizing content items221as can be appreciated.

The administrative client205is representative of one or more devices that may be coupled to the network209. The administrative client205may comprise, for example, a processor-based system such as a computer system. Such a computer system may be embodied in the form of a server, computing environment, desktop computer, a laptop computer, personal digital assistants, cellular telephones, smartphones, set-top boxes, music players, web pads, tablet computer systems, game consoles, electronic book readers, or any other devices with like capability.

The administrative client205may be configured to execute various applications such as an administrative application251and/or other applications. The administrative client205may be configured to execute applications beyond the administrative application251such as, for example, mobile applications, email applications, instant message applications, and/or other applications. The administrative application251may correspond, for example, to a browser, mobile application, or other type of special purpose application that accesses and renders network pages, such as web pages, or other content served up by the content management application215for the purposes of administering the content management system.

The administrative client205comprises a computing device on which an administrative user can communicate with the content management application215via the network209to access user interfaces that facilitate management, updating, and other administrative tasks with respect to a content management system. For example, an administrative user can, via the administrative application251, access administrative functionalities provided by the content management application215as discussed herein and as can be appreciated by a person of ordinary skill in the art.

The data consumer206is representative of one or more devices that may be coupled to the network209. The data consumer206may comprise, for example, a processor-based system such as a computer system. Such a computer system may be embodied in the form of a server, computing environment, desktop computer, a laptop computer, personal digital assistants, cellular telephones, smartphones, set-top boxes, music players, web pads, tablet computer systems, game consoles, electronic book readers, or any other devices with like capability.

The data consumer206may be configured to execute various applications such as a data consumer application245and/or other applications. The data consumer206may be configured to execute applications beyond the data consumer application245such as, for example, mobile applications, email applications, instant message applications, and/or other applications. The data consumer application245may correspond, for example, to a browser or mobile application that accesses and renders network pages, such as web pages, or other network content served up by the content management application215. The data consumer application245may also represent, for example, a web server or other application tasked with assembling a dynamically generated web page from content items221via the content management application215. In such a scenario, the data consumer application245can access content via a web services API provided by the content management application215and insert content items221into content pages generated by the data consumer application245.

Accordingly, the content management application215, as noted above, can facilitate a content management system in that it can provide access to content items221in the data store212to data consumers206for various purposes. Additionally, the content management application215can facilitate management of content items221stored in the data store212. In one embodiment, the content management application215can facilitate the creation of transcripts that correspond to spoken words within content items221(e.g., audio content, video content). Accordingly, the content management application215can perform a speech to text analysis of content items221having a content type231corresponding to audio and/or video content to generate a transcript of the content item221. The transcript generated by the content management application215can be stored as meta data233of the content item221in the data store212and can also identify time codes in the content item221in which the identified spoken words occur. In some embodiments, the content management application215can generate tags that correspond to the words appearing in the transcript and tag the content item221and/or its corresponding meta data233.

The content management application215can also perform an image recognition analysis of video content in the data store212to identify textual content that appears within images and/or video frames of a content item221. The content management application215can then tag the content item221with identified text in the meta data233of the content item221.

Accordingly, using the transcript and/or tags generated by the content management application215after an analysis of a content item221, the content management application215can facilitate search and retrieval of content items221that match a certain search term. Such a search can also yield particular portions of a content item221that are related to a search term (e.g., a clip of a content item). Additionally, the content management application215can also provide editing functionality that allows an administrative user to edit the content item221or a portion thereof that is related to the search term.

Therefore, in one example, if the name of a product that is discussed in a training module in a learning content management system has changed, the content management application215can perform a search of the content items221in the data store and/or a particular node of a content hierarchy223to identify those content items221that contain the name of the product (e.g., by identifying content items221being tagged with the name or in which the name appears in its transcript). The content management application215can then facilitate editing of the content items221by replacing portion of a video, redubbing an audio track containing the name, removing a portion of the video and/or audio, as well as adjusting an audio track equalization settings.

The speech to text analysis performed by the content management application215can also facilitate other content management tasks. For example, the content management application215can facilitate identification of content anomalies such as an audio anomaly. As one example, the content management application215can identify interjections, verbal stutters or ticks, non-lexical utterances, etc., that occur within the audio of a content item215. Audio anomalies can also comprise white noise that is present in an audio track associated with a content item215. An audio anomaly can also include extended periods of silence or near silence in an audio track. In other words, the audio anomaly can include a predetermined amount of time where a volume level is substantially constant in an audio track associated with the content item. These audio anomalies can be flagged by the content management application215and subsequently removed via an automated or manual task. The content management application215can flag such an anomaly by flagging a time code associated with the anomaly in the meta data233of the content item221. An audio anomaly can also comprise any other noises or sounds that may serve as a distraction to a consumer of a content item215that includes audio or video. For example, background noises that exceed a certain volume level can be identified and flagged. More generally, any sounds in the content item221that have a frequency and/or volume that is outside of a specified range of acceptable frequency and/or volume levels can be flagged in the content item221via a time code of the anomaly in the meta data233.

The content management application215can also be configured to identify audio and/or video anomalies that are potentially intentionally inserted into a content item221for later identification or retrieval. For example, when filming a video for inclusion into a content management system, users may intentionally introduce an audio anomaly as a cue for later identification. As one case, if a user misspeaks when filming a video segment for inclusion into the content management system, the user may clap or speak one or more words and continue filming the segment. Subsequently, when the video is incorporated into the data store212, the content management application215can identify such a cue and facilitate easy access to and editing of the content item215by an administrative user. As another case, a user may insert a video cue, such as a clapperboard cue, that can be identified for later retrieval and editing of the content item221.

The content management application215can also identify video anomalies that may occur within video content in the data store212. Accordingly, the content management application215can perform an image recognition analysis of video content in the data store212to identify whether the look and feel of the video complies with style guidelines. For example, the content management application215can analyze the orientation of textual content and/or imagery within a content item221to determine, for example, whether they comply with style guidelines that specify fonts for on-screen textual content as well as orientation and/or positioning of textual or other types elements (e.g., whether certain elements are centered, horizontal positioning, vertical positioning, etc.).

The content management application215can also determine the presence and/or absence of certain video elements in a content item221as specified by content guidelines or rules. For example, the content management application215can determine whether a certain lead-in and/or lead-out or other visual element (e.g., credit sequence, title sequence, headers, footers, etc.) is present within a particular content item221and flag the content item221for an administrative user.

Reference is now made toFIG. 3, which illustrates an example of how the content management application215can facilitate detection and/or removal of content anomalies in content items221in a content management system. In the depicted example, a user interface300is shown that can be generated by the content management application215and rendered in an administrative client205. In the example user interface300, the content management application215can identify audio anomalies associated with a particular content item221and allow an administrative user to view the content item221and/or portion of the content item221associated with the detected anomalies. In the example ofFIG. 3, the content management application215can display the transcript or a portion thereof that is associated with the content item221in the meta data233in the data store212. Additionally, the user interface300can allow the administrative user to remove the anomaly from content item. Additionally, the content management application215can also provide other content editing functionality so that an administrative user may remix or otherwise manipulate the content item221as can be appreciated.

Reference is now made toFIG. 4, which illustrates another example of a user interface400that can be generated by the content management application215and rendered in an administrative client205. In the depicted example, a search results user interface is shown that is responsive to a search query submitted by a user, such as an administrative user. In response to receiving a search query, the content management application215can identify content items221in the data store212that are relevant to the search query based upon the meta data233of the various content items221. For example, as noted above, the meta data233can include one or more tags as well as a transcript identifying the spoken words within the content item221.

As shown inFIG. 4, a user can submit a search query that can related to, for example, content that the user wishes to update in the content management system. Accordingly, the content management application215can locate content related to the search query from among content items221in the data store212and present the search results to the administrative user in the user interface400shown inFIG. 4.

Continuing the example ofFIG. 4, reference is now made toFIG. 5, which illustrates an example of a user interface500that can be generated by the content management application215and rendered in an administrative client205. In the example ofFIG. 5, the administrative user has selected one of the search results shown in the example ofFIG. 4. Accordingly, in the user interface500ofFIG. 5, the content management application215can present to the user portions of the content item221that incorporate the search term by identifying from the transcript associated with the content item221a time code corresponding to the search term. In other words, the content management application215can identify the various occurrences in the content item215of the search term submitted by the user.

Accordingly, the content management application215can also provide editing capabilities to allow the user to redub, remove, or perform other editing functions to the portion of the content item221containing the search term. Furthermore, as shown in the depicted example, the administrative user can also browse the content item221for other occurrences of the search term and perform editing functions to portions of the content item221at which the remaining occurrences exist.

As noted above, content anomalies can comprise anomalies related to sound, imagery, placement of video elements, orientation of textual elements, the look and feel of textual elements, and other anomalies as can be appreciated. In box705, the content management application215can identify time codes in the content item221that are associated with the detected content anomalies. In box707, the content management application215can generate corresponding time codes that correspond to the content anomalies, and in box709, the flags can be associated with the meta data233of the content item221in the data store212. As noted above, the content management application215can also provide editing functionality that allows an administrative user to edit the content item221to remove, redub, or otherwise manipulate the content item221in response to detection of content anomalies.
