Abstract: This application relates to an apparatus for adaptive conversation. In one aspect, the apparatus includes a server communication circuit that forms a communication channel with a user terminal and a server processor functionally connected to the server communication circuit. The server processor may receive, from the user terminal, a user utterance and surrounding external information acquired at a point in time at which the user utterance is collected. The server processor may also generate one word input by combining the surrounding external information with input information generated by performing natural language processing on the user utterance. The server processor may further generate a response sentence by applying the word input to a neural network model, and transmit the response sentence to the user terminal.

Abstract: There are provided a method and a system for automatically generating a back-channel in an interactive agent system. According to an embodiment of the disclosure, an automatic back-channel generation method includes: predicting a back-channel by analyzing an utterance of a user inputted in a back-channel prediction model; and generating the predicted back-channel, and the back-channel prediction model is an AI model that is trained to predict a back-channel to express from the utterance of the user. Accordingly, a back-channel is automatically generated by utilizing a back-channel prediction module which is based on a language model, so that a natural dialogue interaction with a user may be implemented in an interactive agent system, and quality of a dialogue service provided to a user may be enhanced.

Abstract: Provided are a method for segmenting sign language into morphemes, a method for predicting morpheme positions, and a method for augmenting data. A system for analyzing sign language according to an embodiment of the present invention comprises: a recognition unit which recognizes key points of a speaker from a sign language video; and a prediction unit which inputs the recognized key points into an artificial intelligence model, segments the sign language into morphemes, and predicts position information of the segmented morphemes. Accordingly, by recognizing the morphemes of the sign language video frame by frame on the basis of a skeletal model and thereby segmenting the sign language into morphemes and predicting morpheme positions, it is possible to lay the foundations for accurate sign language translation.

Abstract: There is a method for monitoring emotion and behavior occurring during a conversation with a user who is in need of protection. According to an embodiment, a user monitoring method receives an input of a user utterance and generates a conversation content by using a conversation model based on a user utterance content, converts the generated conversation content into a voice and outputs the voice, and recognizes emotion of the user by using an emotion analysis model based on the user utterance content and monitors the emotion. Accordingly, the method may monitor behavior/emotion of a user through a natural conversation while allowing a specialist/guardian to monitor an abnormal sign of a user who is in need of protection.

Abstract: There are provided a method and system for automatic augmentation of gloss-based sign language translation data. A system for automatic augmentation of sign language translation training data according to an embodiment includes: a database configured to store a sequence of sign language glosses and a sequence of spoken-language words in pairs; and an augmentation module configured to augment the pairs stored in the database. Accordingly, gloss-based training data of high quality may be acquired by performing automatic augmentation for gloss-based training data for sign language translation in an efficient method in terms of time and economic aspects, and eventually, accuracy of translation between sign language glosses and sentences may be enhanced.

Abstract: There are provided a method and a system for generating human motions, which generate motions of an empty frame by using motions in a given frame. A human motion generation method according to an embodiment includes: a first step of transforming, by a system, a domain of pose information of a frame; a second step of generating, by the system, motion features of an empty frame in the transformed domain; and a third step of inversely transforming, by the system, the generated motion features into a time domain. Accordingly, the method and system may effectively generate motions by obtaining a basis vector to be used for transforming a domain of motion trajectory information by training a deep learning-based transform model, transforming a motion trajectory through the basis vector, and inputting the transformed motion trajectory to a motion generation model.

Abstract: There are provided a method for segmenting a sign language video by gloss to recognize a sign language sentence, and a method for training. According to an embodiment, a sign language video segmentation method receives an input of a sign language sentence video, and segments the inputted sign language sentence video by gloss. Accordingly, there is suggested a method for segmenting a sign language sentence video by gloss, analyzing various gloss sequences from the linguistic perspective, understanding meanings robustly in spite of various changes in sentences, and translating sign language into appropriate Korean sentences.

Abstract: There is provided a conversation method and system for operating a conversation model according to the presence or absence of related knowledge. A conversation method according to an embodiment may receive an input of a user utterance, may determine a conversation model based on an inputted user utterance content, may create a conversation content by using the determined conversation model, and may convert the created conversation content into a voice, and may output the voice. Accordingly, different conversation models may be operated according to the presence or absence of related knowledge, so that an empathic conversation may be generated instead of generating an inappropriate response in a knowledge-based conversation, and user's satisfaction on a conversation may be enhanced.
