Abstract: Disclosed is a random sampling-based collective classification method and system for Sybil account detection. A random sampling-based collective classification method performed by a collective classification system may include performing a first collective classification using training data; constructing sampled new training data by randomly extracting a portion of the entire nodes based on a label assigned to each node according to a result of performing the first collective classification; performing a second collective classification using the constructed new training data; and applying a posterior score difference of each node computed through the first collective classification and the second collective classification to a prior score of each node to be used for training data at a next iteration.

Abstract: A method of preparing a food composition for an egg fluid substitute or for a milk substitute is described, including a step of lysing microorganisms, and corresponding food compositions prepared by such method. The egg fluid substitute or milk substitute changes into a gel having properties similar to egg fluid when heated and exhibits excellent foaming performance, and can replace egg fluid in a wide range of food applications, including confectionery and baking. The described method enables the production of an egg fluid substitute or milk substitute in an environmentally friendly and sustainable manner, and provides a method for utilizing nutritionally valuable microorganisms as an egg fluid substitute or a milk substitute, as well as contributing to the food industry by expanding the choice of food ingredients.
