A technological software solution is proposed for metric search and identification of logical-temporal patterns of a business data flow by creating additional vector data structures and a parallel method for their processing. The subject of research is the methods of searching and identifying logical-temporal patterns in big data. The purpose of the study is to increase the efficiency of searching and recognizing logical-temporal patterns that semantically form business functionality in an 8-hour frame of screenshots with "garbage" data. Applied methods: apparatus of set theory and Boolean algebra, metric models for determining parameters for sets of binary vectors, elements of probability theory, theory of algorithms, software modeling. The results obtained: a method for searching and recognizing patterns based on a vector problem of character sequences that identify patterns in big data streams using unitary coding of information primitives and data; vector models are unitary-encoded data structures for describing a big data flow as Cartesian products of a set of primitive-string-markers and a discrete sequence of implementation of a given time frame. The practical significance of the work: the implementation of the vector method, which made it possible to create a pattern recognition program in a big data stream with a probability of 0.77%.
