Abstract: The present invention relates to an in-document search method and device for a query vector, and an object of the present invention is to improve the accuracy of a response by generating sentence data corresponding to data in a table form stored in database. The in-document search method for a query vector includes a step A of receiving a user query from a user terminal, a step B of generating a user query vector for the user query, a step C of extracting candidate table data based on the user query vector in a data storage module, a step D of searching for a response corresponding to the user query vector in the candidate table data, and a step E of providing the response to the user terminal.

Abstract: Disclosed herein is a search method including: generating a user question vector for a user question using a paraphrase model learned using first learning data composed of a first pair of questions and a label indicating that the first pair of questions are similar to each other and second learning data composed of a second pair of questions and a label indicating that the second pair of questions are dissimilar to each other; selecting a similar question based on a similarity analysis result to the user question vector; and determining an answer to the similar question as an answer to the user question.

Abstract: An apparatus for waterproofing a battery cover in a portable terminal is provided, in which a rear case includes an opening for accommodating a battery, a battery cover covers the rear case, and a waterproofing module is disposed between the rear case and the battery cover. The waterproofing module is disposed along an inner periphery of the opening, thus sealing a water infiltration path between the battery cover and the rear case.

Abstract: The present invention relates to a method for biologically treating carbon dioxide using the sulfur-oxidizing chemolithoautotroph Sulfurovum lithotrophicum 42BKT. The method of the present invention may enable carbon dioxide to be fixed or converted in high-concentration and high-pressure conditions which do not allow the biological photosynthetic conversion of microalgae or the like, and may exhibit high efficiency in the fixation of carbon dioxide as compared to existing methods for biologically treating carbon dioxide using microalgae. Further, the method of the present invention may use a gas mixture without a process of separating nitrogen and other gases, thus simplifying the process of the fixation or conversion of carbon diode.
