Abstract:
Method for Collaborative Learning Based on Think-Group-Share Strategy in an Intelligent Collaborative Learning System The present invention provides a method for providing collaborative learning for learners. The method is designed based on a "Think- Group-Share" model where the learners are recommended (202) learning materials (204) and being grouped (210) in a plurality of learning groups. The learners are then being tested (212) with a set of questions and they share (218) answers with the other learners, so that the learners could evaluate (220) the answers. The evaluation results is taken as reference for recommending (228) further learning materials (204). An e-learning platform is also provided herewith.
Abstract:
Method for Collaborative Learning Based on Divide-Master-Lead Strategy in an Intelligent Collaborative Learning System The present invention provides a method for providing collaborative learning for learners. The e-leaming model provides a "divide-master- teach" strategy where the learners are divided (202) in groups where the learners try to master the learning materials as a group. A group leader is selected (212) for each group, and the group of learners will be tested with a set of questions assigned to them. The learners are to evaluating (230, 238, 240) the answers and the interactions between the learners. The evaluation results are utilized for recommending new reading materials and selecting new leaders for the groups. An e-learning platform is also provided herewith.
Abstract:
The present invention relates to a method for converting a knowledge base (110) to binary form. The method includes converting ontology and conceptual structure of a knowledge base (110) to binary form. An ontology translator (121) converts the ontology of a knowledge base (110) to conceptual binary array (CBA) and descendant's binary array (DBA), while a conceptual structure translator (122) converts the conceptual structure of a knowledge base (110) to CBA, relations binary array (RBA) and graph binary array (GBA).
Abstract:
A system (100) for the evaluation of effectiveness of learning content comprising: a learning content repository (101) containing learning content; an assessment repository (102) that contains assessment questions; a learning activity storage module (106) that stores learning activity of a learner (104); a feedback storage module (107) for storing feedback from the learner; a sentiment analysis module (109) adapted to analyse the feedback; an assessment results module (108) adapted to receive assessment results based on the assessment questions and analyse the assessment results; and an evaluation engine (110) adapted to generate an evaluation report on the basis of (i) the learning activity of the learner (104), (ii) sentiment analysis information generated from the feedback of said learner (104), and (iii) assessment result analysis information generated from the assessment results.
Abstract:
The present invention relates to a method for translating a knowledge base. The method comprises the steps of extracting a first semantic network notation (SN1) from a first knowledge base; translating SN1 into a second network notation (SN2) by using a series of SN1 to SN2 translation rules; translating a SN2 into SN1 by using a series of SN2 to SN1 translation rules; storing the translated SN1 in a second knowledge base; and validating the translations.
Abstract:
A system and method for automated generation of learning object from online social content by producing a list of semantic tags through an Entity Recognition System upon matching of concepts in domain ontology. The system of the present invention includes a plurality of Social Contents (202); a plurality of Recognition Engines which includes at least one Entity Recognition Engine (302, 414), at least one Speech Recognition Engine (416), at least one Image Recognition Engine (428); at least one Semantic Tag Enrichment Engine (308); at least one Social Content knowledge base (206); and at least one Learning Object knowledge base (210). The at least one Entity Recognition Engine (302, 414) having means for receiving Learning Object that is associated with description, learning objective and learning outcome; producing a list of semantic tags upon matching of concepts in domain ontology; and forwarding said list of semantic tags to at least one Semantic Tag Enrichment Engine for metadata enrichment. In short, the present invention provides for automated generation of LO from social contents through LO enrichment; social content selection and metadata enrichment and thereafter composing complete LO which includes text, image and video.
Abstract:
A method (100) and system (200) for ontology navigation and visualization, the system (200) comprises an ontology navigator (202). The ontology navigator (202) comprises means for graphically displaying a plurality of concepts (102) of at least one ontology knowledge base (206), receiving a user query of at least one concept from the plurality of concepts (104), identifying a visualization application (204) for visualizing the at least one concept (106), generating an information set (108) of the at least one concept recognized by the visualization application (204), and forwarding the information set (110) of the at least one concept to the visualization application (204).
Abstract:
The present invention relates to a system and method for semantic level sentiment analysis. The system (100) comprises of a graph generator component (10), a semantic sentiment analyser component (20), a sentiment processor component (30), a sentiment dictionary (40), a sentiment taxonomy (50), a semantic sentiment patterns repository (60) and a propagation rules repository (70). The system (100) accepts text data as input and analyses sentiment in the text. The method enables semantically valid sentiment in terms of the entire text as well as the individual entities in the text.
Abstract:
The present invention relates to a system and method for creating a Learning Object (LO) from a document. Particularly, the system (100) automatically generates the LO at sentence level, paragraph level and topic level in different modalities such as text, image, audio and video. The system (100) comprises a mapper (130), a ranker (140) and a Learning Object Builder (150). The method for creating a Learning Object from a document includes the steps of analysing and processing a document received from a user, matching a retrieved semantic structure by sentence index with a semantic structure from a multimedia repository (120) by the mapper (130), selecting and ranking projected graphs for each type of multimedia by the ranker (140) and producing the Sentence Learning Object, Paragraph Learning Object and Topic Learning Object by the Learning Object Builder (150).
Abstract:
The present invention relates to an image processing system (100). The image processing system (100) is able to compute and analyse spatial relationship between objects detected in an image. The image processing system (100) comprises of an image segmentation and labelling component (110), a blob detection component (120), a spatial relationship extractor component (130), and a domain knowledge base (140). The image processing system (100) extracts spatial relationship between objects in an image by performing a surface subdivision computation, two-dimensional spatial relation computation, three-dimensional spatial relation computation and spatial relation extender.
