Abstract: The invention relates to a method and a system for improving performance of text summarization and has an object of improving performance of a technique for generating a summary from a given paragraph. According to the invention to achieve the object, a method for improving performance of text summarization includes: calculating a first likelihood of each of a plurality of nodes included in a graph corresponding to a natural language-based context; calculating a second likelihood of each of the plurality of nodes by assigning a weight to a first likelihood of a node corresponding to a keyword not presenting in the context among a plurality of keywords corresponding to each of the plurality of nodes; calculating a third likelihood of each of all paths present in the graph based on the second likelihood of each of the plurality of nodes; and generating a summary for the context based on a path having the highest third likelihood among the paths.

Abstract: The present invention relates to a nonoxidative methane direct converting reactor and a preparation method of ethylene and aromatic compound using the same and, more specifically, to a nonoxidative methane direct converting reactor and a preparation method of ethylene and aromatic compound using the same, wherein the reactor maximizes a catalytic reaction rate, minimizes cokes production, and provides a high conversion rate of methane and a high yield of ethylene and an aromatic compound even at a low hydrogen supply ratio in the production of ethylene and an aromatic compound from methane.

Abstract: An apparatus and method for welding electrode tabs protruding from an electrode assembly to each other which may include a guide part configured to gather the electrode tabs on a predetermined gathering area, a welding part configured to weld the electrode tabs gathered by the guide part, and a bending part configured to bend the electrode assembly. The bending part ensures that a length from the electrode assembly to the gathering area increases in at least a portion of the electrode tabs before being welded by the welding part. Accordingly, some aspects of the present invention may prevent the electrode tabs from disconnecting. Moreover, the present invention also relates to a secondary battery and may relate to a secondary battery manufactured by the above-described welding apparatus or method.

Abstract: A blood flow measurement device according to various embodiments may be configured to irradiate light to a first position of a subject and a second position of the subject located in a first direction with respect to the first position, acquire intensities of the reflected light at the first position and the second position, determine a first value which is a difference between the intensities of the reflected light at the first position and the second position, irradiate light to a third position of the subject located in a second direction with respect to the second position, acquire an intensity of the reflected light at the third position, determine a second value which is a difference between the intensities of the reflected light at the second position and the third position, and determine a blood flow direction based on the first value and the second value.

Abstract: A high-quality voice signal processing device through removal of ambient noise based on multi-sensor signal fusion, includes: a voice microphone sensor that senses and outputs a speaker's voice signal; an accelerometer sensor that senses vibration of the speaker's vocal cords and outputs a signal; a noise reduction processing MCU that extracts a voice section according to vocal cord vibration using the output signal of the accelerometer sensor, synthesizes a low-frequency component of the accelerometer sensor and a low-frequency component of the voice microphone sensor at different synthesis ratios based on a level of noise extracted from the output signal of the voice microphone sensor using voice section information, and restores and outputs a voice signal by adding the synthesized low-frequency components and a high-frequency component of the voice microphone sensor; and a wireless communication module that externally outputs the restored voice signal.
