Present methods used to deliver content to users do not involve correlating a measure of complexity of the content with various interactions a user may have before, during, and after the presentation of the content. Present approaches are not specific to a particular user. Moreover, these approaches do not facilitate determining a depth and/or breadth of understanding of concepts discussed in the content by the user.
Present content delivery techniques were not designed with flexibility for content adjustment during the course of coaching through content delivery. For example, a user might press play on a playback device and then listen to and/or watch predetermined presented content. Thus the extent to which the content can be altered and/or rearranged and/or modified with such techniques is limited (e.g., if the user replayed the content, the user would see and/or hear the exact same presentation again). This approach is not tailored to a specific user, and results in a lack of effectiveness in meeting the goal for which the content is presented and/or the user is coached.
System 10 ensures that a user has understood the content and/or the information conveyed through the content at specific instances, before proceeding further so as to make the coaching meaningful and effective in meeting the goal and/or the purpose for which the user is exposed to such content.
System 10 is configured to analyze and segment the content based on semantic concepts present in the content, measure the complexity of the content based on at least one complexity parameter, and provide the content to user 22 based on the complexity of the content. In some embodiments, system 10 analyzes content using semantic ontology to identify semantic concepts; segments the content into one or more content segments based on identified semantic concepts; determines the complexity measure of the content based on a weightage of the identified semantic concepts; and presents the one or more content segments based on complexity measure. For example, content corresponding to heart failure may be presented to the user. In this example, system 10 may analyze the content to identify semantic concepts (topics) such as heart attack, high blood pressure, and/or other semantic concepts. System 10 may segment the content into one or more content segments based on the previously identified semantic concepts (e.g. heart attack, high blood pressure) and associate segments including similar topics into a sequence of topics for presentation. In this example, system 10 may determine the complexity measure of previously identified topics by adding the number of concept nodes (described below) with a weightage assigned to each semantic concept increased by one. System 10, presents the one or more content segments based on the determined complexity measure of the semantic concepts such that more difficult and/or challenging semantic concepts are presented when the user has understood less difficult and/or basic concepts. In some embodiments, system 10 comprises one or more of a processor 12, electronic storage 14, external resources 16, a computing device 18, and/or other components.
Processor 12 is configured to provide information processing capabilities in system 10. As such, processor 12 may comprise one or more of a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information. Although processor 12 is shown in
As shown in
It should be appreciated that although components 26, 28, 30, 32, and 34 are illustrated in
Content analysis component 26 is configured to analyze the content using semantic ontology to identify semantic concepts in the content. The content may be a video and/or textual information (e.g., closed captions of a multimedia video), or information in any other form intended to provide information on a topic related to a clinical condition and/or a clinical plan or goal. Semantic concepts include and/or refer to different topics included in the content. In some embodiments, an individual semantic concept may be indicated by a plurality of linked keywords corresponding to an individual topic of the content. In some embodiments, semantic ontology is a lexical database which groups words into sets of synonyms, records relations among the synonyms, and provides short definitions and usage examples regarding the synonyms. In some embodiments, semantic ontology may include nomenclature of medicine and clinical terms. In some embodiments, semantic ontology may include a dictionary and thesaurus. For example, content analysis component 26 may utilize a semantic ontology (e.g. WordNet™ for non-medical concepts or SNOMED-CT™ for medical concepts) to identify semantic concepts (e.g. Heart Failure) in the closed caption of the multimedia video. Individual semantic concepts may have a varying degree of complexity, and may be related to other semantic concepts within the same content. In some embodiments, the interrelated semantic concepts may be visualized and/or analyzed in a tree form having various topics and keywords representing individual semantic concepts. By way of a non-limiting example,

The content complexity analysis component 30 is configured to determine a measure of complexity of the one or more content segments based on a weightage of the identified semantic concepts. In some embodiments, the weightage of the identified semantic concepts may be determined by the hierarchical level of the identified semantic concepts. For example, as illustrated in
In some embodiments, the measure of complexity is determined by adding the number of the concept nodes to a sum of a complexity measure of each of the identified semantic concepts. In some embodiments, the complexity measure of each of the identified semantic concepts may be determined by increasing a weightage of each of the identified semantic concepts by one. In some embodiments, measure of complexity may be determined using hop length method wherein the terms of a semantic concept are utilized to determine basic, intermediate and advanced semantic concepts in the content. For example, addition (e.g. 2+3) may be a simple concept in mathematics, and multiplication may be a concept that depends on addition (e.g. 5×5=(2+3)×(2+3)); thus multiplication is more complex than addition. In this example, until user 22 has understood the concept of addition, user 22 may find the concept of multiplication difficult to comprehend. In some embodiments, measure of complexity may be hop length indicated by a depth and a breadth of a concept. In some embodiments, a depth of a semantic concept is determined by a number of parent semantic concepts. In some embodiments, a breadth of a semantic concept is determined by a number of links associated with a semantic concept. For example, user 22 has to understand blood circulation, oxygenation flow, and muscular function of heart semantic concepts before learning heart failure semantic concept. In some embodiments, determination of the complexity measure of each of the identified semantic concepts, may include a two-step process. The two step process may include a) determining the complexity measure of each of the identified semantic concepts based on a domain knowledge point of view; and b) determining the complexity measure of each of the identified semantic concepts based on a user's point of view. Determination of the complexity measure based on a domain point of view includes measuring the complexity of each of the identified semantic concepts based on a corresponding weightage as determined by the semantic ontology relative to one or more of a discipline, a field of study, and/or a subject area. Determination of the complexity measure based on a user's point of view includes measuring the complexity based of each of the identified semantic concepts based on one or more of the user's education level, the user's prior exposure to each of the identified semantic concepts, the user's scientific knowledge about each of the identified semantic concepts and/or other factors. For example, to a user who has never been exposed to a given field, a simpler concept, as measured based on domain knowledge, may be complex, and to an expert user, a complex concept, as measured based on domain knowledge, may be a simpler concept.
By way of a non-limiting example, Table 2 illustrates complexity measured for various semantic concepts in the video (e.g., content) wherein a combination of number of measurable parameters is used to determine the overall complexity measure of each of these concepts. User 22 may be a patient with chronic heart failure and a lower level of education. In this example, it may be required for user 22 to understand the individual semantic concepts relating to heart rate, ankle swelling, and/or other semantic concepts from the video in order to understand heart failure. In some embodiments, overall complexity measure of individual semantic concepts may be illustrated by numbers (e.g. 1 for simple semantic concepts, 2 for difficult semantic concepts, 3 for very challenging semantic concepts). In some embodiments, overall complexity measure of individual semantic concepts may be illustrated by skill level (e.g. Basic, Intermediate, Advanced). In some embodiments, the content complexity analysis component 30 may illustrate video semantic graph transition probabilities.

Content presentation component 32 is configured to effectuate presentation of the one or more content segments to user 22 based on the determination of the measure of complexity of the one or more content segments. In some embodiments, effectuating presentation of the one or more content segments includes one or more of presenting rearranged, altered, modified, fragmented, combined, or replaced content segments. Rearranging content segments may include changing a presentation time of each of the content segments. Altering and/or modifying the one or more content segments may include changing textual or visual information corresponding to the content segments prior to presentation of the respective content segments. Fragmenting the one or more content segments may include dividing the content segments into smaller portions and presenting each of the smaller portions independent of one another. Combining content segments may include combining a plurality of similar content segments and/or other content segments prior to presentation of the content segments. Replacing content segments may include substituting one content segments for another content segment. For example, a content segment describing High Blood Pressure may be presented in fragmented components of nutrition, exercise, genetic heredity, and/or other components. In some embodiments, the analysis of the content to identify sematic concepts, the segmentation of the content, and/or the determination of the measure of complexity of the content or content segments therein may be performed prior to the presentation of the content or content segments therein. In some embodiments, the analysis of the content to identify sematic concepts, the segmentation of the content, and/or the determination of the measure of complexity of the content or content segments therein may be performed during at least a portion of the presentation of the content or content segments therein. As an example, the content or content segments to be presented to a user may be rearranged, altered, modified, fragmented, combined (e.g., with one or more other content segments), or replaced during presentation of at least a portion of the content to a user such that one or more rearranged, altered, modified, fragmented, combined, or replaced content or content segments may be presented to the user during the same presentation of the content in a dynamic fashion. In some embodiments,
Complexity visualization component 34 is configured to, responsive to the determination of the measure of complexity of the identified semantic concepts and a timestamp corresponding to the identified semantic concepts, effectuate presentation of a visualization of the measure of complexity, the visualization including a statistical probability graph, a bar chart, or a timeline chart. By way of a non-limiting example,
