摘要： A method and a system for Augmented Reality (AR) content creation is disclosed. The method includes creating a feature vector corresponding to each of a sequence of frames extracted from a video, based on a plurality of features captured. The method further includes determining a vector distance between each of two consecutive frames from the sequence of frames, based on the feature vector associated with each of the two consecutive frames. The method further includes dividing the video into a plurality of frames based on the determined vector distance. The method further includes creating a storyline based on an object and an action associated with the object in each of the plurality of frames, and generating a set of instructions for a user based on the storyline created for each of the plurality of frames and real-time video stream capturing a current state of a user environment.

摘要： The present invention relates to a method for generating abstractive summary. The method comprises receiving a query for generating an abstractive summary from a document and splitting the query into one or more lexical units. Further, a semantic graph and a graph index is generated based on a role assigned to the one or more lexical units. Furthermore, a measure of information is determined for the retrieved one or more sentences. The one or more sentences having a semantic graph analogous to the generated semantic graph of the query are retrieved from the document. Finally, at least one of re-ordering and re-phrasing is performed on at least one of the retrieved one or more sentences based on the computed measure of information and the one or more lexical units in the retrieved one or more sentences to generate the abstractive summary.

摘要： A method of identifying relevant keywords from a document is disclosed. The method includes splitting text of the document into a plurality of keyword samples, such that each of the plurality of keyword samples comprises a predefined number of keywords extracted in a sequence. Further, each pair of adjacent keyword samples in the plurality of samples includes a plurality of common words. The method further includes determining a relevancy score for each of the plurality of keyword samples based on at least one of a trained Convolution Neural Network (CNN) model and a keyword repository. The method further includes classifying keywords from each of the plurality of keyword samples as relevant keywords or non-relevant keywords based on the relevancy score determined for each of the plurality of keyword samples.

摘要： The present disclosure relates to method and system for providing context-based response for a user query. The method comprises generating current graphical structure for user query received from user which comprises one or more nodes corresponding to one or more words in the user query and one or more edges connecting the one or more nodes. Each node in the current graphical structure is associated with predefined indexing identification (ID) which is compared with predefined indexing IDs of one or more predefined graphical structures to identify one or more related predefined graphical structures. The one or more related predefined graphical structures are ranked based on number of predefined indexing IDs being matched. Based on comparison, system provides response corresponding to predefined question associated with related predefined graphical structure with highest rank. Therefore, present disclosure provides an efficient mechanism for providing context-based response to user queries.

摘要： The present invention discloses method and system for multimodal analysis based emotion recognition. The method comprising segmenting video data of a user into a plurality of video segments. A plurality of visual features, voice features and text features from the plurality of video segments is extracted. Autocorrelation values among each of the plurality of visual features, the voice features, and the text features is determined. Each of the plurality of visual features, the voice features and the text features is aligned based on video segment identifier and the autocorrelation values to obtain a plurality of aligned multimodal features. One of two classes of emotions is determined for each of the plurality of aligned multimodal features. The determined emotion for each of the plurality of aligned multimodal features is compared with historic multimodal features from a database, and emotion of the user is determined at real time based on comparison.

摘要： The present disclosure discloses a method and system for providing response to a user input. The system receives a user input, processes the user input by finding equivalents of the user input and dividing each of the user input and the equivalents into a frame. One or more keywords are generated for each of the one or more frames. Further, each of the one or more frames are classified into one or more domains present in a knowledge graph. Then, one or more objects are determined in each of the corresponding one or more domains based on the corresponding one or more keywords. Further, a processing means is determined for each of the one or more objects based on the metadata of the corresponding one or more objects. The processing means is processed by the system for providing response to the user input.

摘要： A method and system of language independent iterative learning mechanism for Natural Language Processing (NLP) tasks is disclosed. The method includes identifying at least one NLP feature associated with a set of words within a sentence for an NLP task. The method includes creating a pattern associated with the sentence for the NLP task, based on the at least one NLP feature associated with the set of words and the linkage relationship between each subset of two adjacent words. The method further includes computing a confidence score corresponding to the pattern, based on a comparison within a trained dataset. The method further includes assigning a pattern category to the pattern, based on the confidence score and a predefined threshold score. The method further includes executing the NLP task based on the assigned pattern category.

摘要： A method and driver assistance system for generating touch-based alerts to a driver in a vehicle is disclosed. The driver assistance system receives frames including the driver in vehicle and detects position of face of the driver in plurality of frames. Facial attributes of the driver are identified based on position of the face and one or more eye attributes of the driver are determined based on the identified one or more facial attributes. Based on the facial attributes and the one or more eye attribute sensory information is estimated from a plurality of sensory data. Further, information regarding haptic sensation is computed for the driver based on estimated sensory information and a position of hands of the driver received from a hand tracking device. Thereafter, an alert is generated using signals relating to the haptic sensation to the driver for taking one or more corrective measure.
