Provided is a method performed by a computing system for providing an integrated chatbot-based service. The method includes receiving, by an integrated chatbot, a query from a user device; extracting a main keyword from the query; transmitting the extracted main keyword to a first chatbot and a second chatbot; receiving, from the first chatbot and the second chatbot, a content search result corresponding to the extracted main keyword; and providing a response to the query to the user device based on the received content search result.

Method for providing service based on integrated chatbot and system thereof

A method of embedding a vector representing an arrangement state of objects in a 3D space according to an embodiment includes dividing a target space into M&#xd7;N subspaces extending from a first surface among planes forming the target space having a cuboid shape, calculating, for each of the subspaces, a feature representing an object arrangement state in the subspace, inputting data representing the feature of each of the subspaces into an artificial neural network and obtaining, from the artificial neural network, an embedding vector representing an arrangement state of an object in the target space.

Apparatus for determining arrangement of objects in space and method thereof

There is provided a tactile feedback device comprising: an array of surface charge generation units; and an array of pressure-generation units, wherein the array of the pressure-generation units is spaced apart from the array of the surface charge generation units, wherein the array of the pressure-generation units is movable relative to the array of the surface charge generation units, wherein an attractive or repulsive force is generated between a corresponding surface charge generation unit of the array of surface charge generation units and a corresponding pressure-generation unit of the array of the pressure-generation units, based on a polarity of surface charges induced in the corresponding surface charge generation unit.
