Abstract: The present invention relates to a fashion product recommendation method for generating first recommended product information and second recommended product information, on which the preference of a user regarding a specific fashion product is reflected, the fashion product recommendation method comprising the steps of: generating, for each product category, attribute categories including at least one piece of attribute information that is a factor characteristically considered when the user selects a fashion product; performing a tournament regarding fashion items including at least one of the attribute categories and assigning a weight to the attribute information to generate the first recommended product information; and additionally assigning a weight to the attribute information according to a filtering result of the user to generate the second recommended product information.

Abstract: A service server includes a product database configured to extract a label describing product details, map the label to a product, and store the label; a query processing unit configured to receive a query to request recommended product information related to a search target object from a user device, recognize the search target object from the received query, and obtain a query label from the recognized search target object; a feature label list providing unit configured to search the product database for one or more candidate recommended products, generate a feature label list based on feature labels selected among feature labels tagged on the one or more candidate recommended products, and provide the feature label list to the user device; and a product recommendation module configured to search the product database for a recommended product, and provide the recommended product information to the user device.

Abstract: The present invention relates to a method, a device, and a system for providing fashion information. Particularly, the system for providing fashion information, of the present invention, comprises: a sample data generation unit for generating sample data in which the same fashion items of various sizes are matched according to human body information; a sample data storage unit for storing the sample data; and a predictive fit data providing unit for receiving, from a user device, fashion item information and user body information, and generating predictive fit data in reference to the sample data stored in the sample data storage unit, wherein the predictive fit data can be referred to size or fit when a user selects the fashion items.

Abstract: The present invention relates to a method for encoding a candidate vector for searching for a neighbor that is nearest to a query in a candidate dataset, the method comprising a normalization step of normalizing an input vector to obtain a direction vector and vector energy; a quantization step of quantizing the direction vector to obtain a code word and a residual vector; a step of repeating the normalization step and the quantization step, as many times as a predetermined number of encoding times, by using the residual vector as an input vector; and a step of encoding the candidate vector by using one or more code words and energy of one or more vectors resulting from the repetition. According to the present invention, a dataset having a very wide range of energy values can be effectively approximated and higher precision thereof can be obtained.

Abstract: The present invention relates to a method, device and computer program for providing image search information. The method for an electronic device to provide image search information according to the present invention comprises: a step of generating a query by using an image if a predetermined query generation event occurs while playing the image; a step of transmitting the query to a server; and a step of receiving a search result corresponding to the query from the server and displaying same on a screen, wherein the search result is a search result of at least one object included in the image. A purpose of the invention is to provide a method, device and program for providing image search information, allowing the search of a product similar to a product exposed in an image, without an additional input of a search word.

Abstract: The preset invention relates to a method for an electronic device to display shopping information, which includes: displaying a shopping information search menu to be fixed in a notification list; running a camera function and displaying a camera preview image upon receiving a user request for a camera search in the shopping information search menu; extracting a search image from the preview image to transmit a query; and displaying shopping information matched to the image by switching a screen or displaying a link to the shopping information to be superposed on the preview image upon receiving the shopping information.

Abstract: The present invention relates to a method, an apparatus, a system, and a computer program in which a server offers product information corresponding to an image displayed on a client and the client displays the product information. A method for offering product information by a server to a client includes: generating a database on a plurality of products and extracting feature information on an image included in the database; receiving an image displayed on the client as a query image from the client; determining a matching product matched to feature information on the query image by retrieving feature information on the image in the database; and offering information on the matching product to the client. According to the present invention, the server may retrieve a database of product information only with an image displayed on the client and may offer product information to the client.
