The presently disclosed embodiments are related, in general, to multimedia content processing. More particularly, the presently disclosed embodiments are related to method and system for content processing to determine pre-requisite subject matters in multimedia content.
The ever increasing advancements in the field of education have led to the usage of Massive Open Online Courses (MOOCs) as one of the popular modes of learning. Several educational organizations, such as Stanford, Harvard, Massachusetts Institute of Technology (MIT), Yale, and Indian Institute of technology (IIT), are making thousands of hours of video lectures that may be available online and free of cost to students for learning purposes. As the amount and demand for these online lecture videos is increasing across the world, it may be essential to develop methods for efficient consumption of these online lecture videos.
The courses offered by MOOCs comprise multiple lecture videos per course. For example, the courses, provided by National Program on Technology Enhanced Learning (NPTEL), have an average of “30” lecture videos per course of an hour each. Further, the lecture videos are in a pedagogical order, which the students may have to follow to finish up the courses. For example, if a student is undertaking a course, then the student may have to watch the lecture videos of the course in the pedagogical order (e.g., lecture-1, lecture-2, lecture-3, . . . , lecture-n), as defined by MOOC provider or lecturer to finish the course. There is no relaxed ordering of the lecture videos in the course, for example, if one or more concepts discussed in “lecture-i” and “lecture-j” are not related, then they may be watched in any order. Further, if the student is interested in a particular lecture of the course, then there is no information available about other lecture videos or parts of lecture videos that may be essential to understand i.e., no pre-requisite information is available for the particular lecture video. The one solution to such problem is to consider all such previous lecture videos as pre-requisite for the lecture video. However, such a solution may be very unrealistic and impractical, especially for informal learners who, in general, access these video lectures for very specific and varied subject matters. In another solution, an individual, such as a subject matter expert, may manually go through each lecture video, and thereafter may create a list of pre-requisites for each lecture video and each subject matter or concept in each lecture video. However, such manual actions for thousands of videos spanning over multiple courses may be an arduous task. Thus, there is required a method and a system for efficient and effective consumption of these online lecture videos by individuals, such as the students.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to a person having ordinary skill in the art, through a comparison of described system with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

For example, the content generating processor 216 may be implemented using one or more of, but not limited to, an X86-based processor, a RISC processor, an ASIC processor, a CISC processor, and/or other such processor.
The transceiver 218 comprises suitable logic, circuitry, interfaces, and/or code that may be configured to receive/transmit the multimedia content or other information from/to one or more computing devices (e.g., the processor 202, the memory 204, the controller 206, the I/O unit 208, the score generating processor 210, the natural language processor 212, the multimedia extracting processor 214, and the content generating processor 216) over the communication network 108. In an embodiment, the transceiver 218 may implement one or more known technologies to support wired or wireless communication with the communication network 108. In an embodiment, the transceiver 218 may include, but is not limited to, an antenna, a radio frequency (RF) transceiver, one or more amplifiers, a tuner, one or more oscillators, a digital signal processor, a Universal Serial Bus (USB) device, a coder-decoder (CODEC) chipset, a subscriber identity module (SIM) card, and/or a local buffer. The transceiver 218 may communicate via wireless communication with networks, such as the Internet, an Intranet and/or a wireless network, such as a cellular telephone network, a wireless local area network (LAN) and/or a metropolitan area network (MAN). The wireless communication may use any of a plurality of communication standards, protocols and technologies, such as: Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for email, instant messaging, and/or Short Message Service (SMS).
At step 304, the one or more input parameters are received from the user-computing device 102. The one or more input parameters may comprise the one or more subject matters associated with the second set of multimedia content that are of interest to the user, the time-related constraint associated with the user, and the preference of the user for the one or more subject matters and their associated pre-requisite subject matters. In an embodiment, the transceiver 218 may be configured to receive the one or more input parameters from the user-computing device 102 over the communication network 108. In an embodiment, the one or more input parameters may be transmitted along with the request for processing the set of multimedia content of the course to determine the one or more of the set of multimedia content that comprise at least one or more pre-requisite subject matters provided by the user.
Prior to transmitting the one or more input parameters, the user may utilize one or more input units of the user-computing device 102 to select at least one course from one or more courses pre-stored in a memory unit of the user-computing device 102. Each course may include the set of multimedia content (e.g., a set of audio content, a set of video content, a set of animation content, or a combination thereof) that are associated with the one or more subject matters of the course. Further, each of the set of multimedia content of the course may be in the pedagogical order that defines at least the sequence in which each of the set of multimedia content is to be inferred by the user to complete the course. The set of multimedia content of the course may be stored in a storage device, such as the memory unit of the user-computing device 102, memory 204, or the database server 104.
In cases where the sequence of multimedia content in the set of multimedia content is not present, the processor 202 may be further configured to determine the sequence of multimedia content in the set of multimedia content. The sequence of multimedia content in the set of multimedia content may be determined by use of an order of occurrence of words in a textbook to decide on the sequence. For example, let us assume a pair of lecture videos, say, “La” and “Lb.” The processor 202 may be configured to determine if “La” should appear before “Lb” or not in the sequence. The words present in “La” are “w1a, w2a, w3a, . . . , wMa” total “M” words). Similarly, the words present in “Lb” are “w1b, w2b, w3b, . . . , wNb” (total “N” words). For each of these words, the processor 202 may be configured to determine a mean occurrence in a relevant textbook, say “Oma” for “La” and “Onb” for “Lb.” Now for each pair of words from “La” and “Lb,” {wma, wnb}, processor 202 may check if the word from “La” appeared before the word from “Lb” in the textbook (only if both these words are present in the textbook). The processor 202 may utilize a pre-defined indicator variable “Imn” which is set as “+1” if the word from “La” appears before the word from “Lb,” else is set as “−1.” Now if the processor 202 determines that Σm,n Imn is positive, then the processor 202 may determine that “La” is before “Lb.” However, if the processor 202 determines that Σm,n Imn is negative, then the processor 202 may determine that “La” is after “Lb.” Similarly, the processor 202 may determine the sequence of each multimedia content in the set of multimedia content. Based on the determined sequence, the processor 202 may identify the pedagogical order of the set of multimedia content.
In another embodiment, the user may utilize the user-computing device 102 to connect to a remote storage server, such as the database server 104, over the communication network 108 to select the course from the one or more courses. After selecting the course, the user may utilize the one or more input units of the user-computing device 102 to transmit the one or more input parameters to the transceiver 218 over the communication network 108. After receiving the one or more input parameters from the user-computing device 102, the transceiver 218 may store the received one or more input parameters in the storage device, such as the database server 104 or the memory 204.
At step 306, the set of multimedia content of the course is extracted or retrieved from the storage device, based on at least the received one or more input parameters. In an embodiment, the multimedia extracting processor 214 may be configured to extract or retrieve the set of multimedia content of the course from the storage device, such as the database server 104, memory 204, or the memory unit of the user-computing device 102, based on at least the received request comprising the one or more input parameters. For example, the multimedia extracting processor 214 may extract or retrieve the set of multimedia content from the storage device based on at least the course selected by the user.
In an embodiment, the multimedia extracting processor 214 may transmit a query to the storage device, such as the database server 104, memory 204, or the memory unit of the user-computing device 102, to extract or retrieve the set of multimedia content of the course. The multimedia extracting processor 214 may generate the query based on at least the selected course and/or the received one or more input parameters. After extracting the set of multimedia content of the course in the pedagogical order, the multimedia extracting processor 214 may further be configured to extract the one or more concepts in each of the extracted set of multimedia content. Prior to the extraction of the one or more concepts, the natural language processor 212 may be configured to determine the one or more subject matters associated with each of the extracted set of multimedia content. The natural language processor 212 may be configured to determine the one or more subject matters based on at least a processing of the audio content (i.e., speech-to-text transcript) and video content associated with each of the extracted set of multimedia content. Based on at least the processing of the audio content and the video content, the natural language processor 212 may be configured to segment each of the extracted set of multimedia content into one or more segments of multimedia content. In an embodiment, each of the one or more segments of multimedia content may correspond to the one or more subject matters. Thereafter, the natural language processor 212 may store the determined one or more subject matters of each of the extracted set of multimedia content in the storage device, such as the memory 204 or the database server 104.
A person having ordinary skill in the art will understand that the scope of the disclosure is not limited to the determination of the one or more subject matters of multimedia content based on the segmentation of the multimedia content. In an embodiment, the one or more subject matters of the multimedia content may be determined by use of one or more techniques known in the art without limiting the scope of the disclosure.
After determining the one or more subject matters of each of the extracted set of multimedia content, the multimedia extracting processor 214 may extract the one or more concepts from each of the extracted set of multimedia content based on at least one of the determined one or more subject matters and the one or more external knowledge databases (e.g., Wikipedia®). In an embodiment, the multimedia extracting processor 214 may utilize one or more techniques based on at least one or more of parts-of-speech (POS) tagging, text rank weighing, or usage analysis to extract the one or more concepts from each of the extracted set of multimedia content. Further, the multimedia extracting processor 214 may store the extracted one or more concepts corresponding to each of the extracted set of multimedia content in the storage device, such as the memory 204 or the database server 104.
At step 308, the set of pre-requisite concepts and the set of outcome concepts are determined for one or more of the extracted set of multimedia content of the course based on the one or more concepts extracted from each of the set of multimedia content. In an embodiment, the processor 202 may be configured to determine the set of pre-requisite concepts and the set of outcome concepts for the one or more of the extracted set of multimedia content of the course based on the one or more concepts extracted from each of the set of multimedia content. Further, in an embodiment, the set of pre-requisite concepts and the set of outcome concepts are determined by the use of the one or more external knowledge databases.
Prior to the determination of the set of pre-requisite concepts and the set of outcome concepts, the processor 202 may be configured to identify the one or more multimedia content from the extracted set of multimedia content. In an embodiment, the processor 202 may identify the one or more multimedia content from the extracted set of multimedia content based on the received one or more input parameters. For example, based on the one or more subject matters that are of interest to the user, the processor 202 may identify the one or more multimedia content from the extracted set of multimedia content. The identified one or more multimedia content may correspond to the second set of multimedia content. For each of the second set of multimedia content, one or more multimedia content in the extracted set of multimedia content that are preceding each of the second set of multimedia content in the pedagogical order may correspond to the first set of multimedia content. As discussed above, based on the received one or more input parameters, the processor 202 may identify the first set of multimedia content and the second set of multimedia content. Thus, the extracted set of multimedia content may comprise at least the first set of multimedia content and the second set of multimedia content, such that the second set of multimedia content follows the first set of multimedia content in the pedagogical order.
After identifying the first set of multimedia content and the second set of multimedia content, the processor 202 may be configured to determine the set of pre-requisite concepts and the set of outcome concepts for each of the second set of multimedia content and each of the first set of multimedia content, respectively.

Further, in an embodiment, the set of extracted one or more concepts comprises the extracted one or more concepts associated with the first set of multimedia content that shall be acquired, learned, or gained knowledge about in advance by the user prior to viewing of the second multimedia content. Similarly, in an embodiment, the set of outcome concepts of a first multimedia content corresponding to the second multimedia content may be determined based on a set of extracted one or more concepts or skills that may be acquired, learned, or gained knowledge about by the user after viewing or going through the first multimedia content. Similarly, the processor 202 may be configured to determine the set of pre-requisite concepts and the set of outcome concepts for each of the remaining multimedia content in the second set of multimedia content and the remaining multimedia content in the first set of multimedia content, respectively.
At step 310, the concept coverage score of the second multimedia content is determined based on the determined set of pre-requisite concepts associated with the second multimedia content and the determined set of outcome concepts associated with at least one of the first set of multimedia content corresponding to the second multimedia content. In an embodiment, the score generating processor 210 may be configured to determine the concept coverage score of the second multimedia content based on the determined set of pre-requisite concepts associated with the second multimedia content and the determined set of outcome concepts associated with at least one of the first set of multimedia content corresponding to the second multimedia content.
