Efficient Implementation of Hadoop MapReduce based Business Process Dataflow

Abstract

Hadoop MapReduce is one of the solutions for the process of large and big data, with-it the authors can analyze and process data, it does this by distributing the computational in a large set of machines. Process mining provides an important bridge between data mining and business process analysis, his techniques allow for mining data information from event logs. Firstly, the work consists to mine small patterns from a log traces, those patterns are the workflow of the execution traces of business process. The authors' work is an amelioration of the existing techniques who mine only one general workflow, the workflow present the general traces of two web applications; they use existing techniques; the patterns are represented by finite state automaton; the final model is the combination of only two types of patterns whom are represented by the regular expressions. Secondly, the authors compute these patterns in parallel, and then combine those patterns using MapReduce, they have two parts the first is the Map Step, they mine patterns from execution traces and the second is the combination of these small patterns as reduce step. The results are promising; they show that the approach is scalable, general and precise. It reduces the execution time by the use of Hadoop MapReduce Framework.

[Retracted] Closed Home Physical Education Teaching Model and Response Strategies Based on Big Data Technology

“…e nationwide online physical education is also a precedent in the history of physical education in China, which shows that online physical education, as a new teaching method, is an inevitable product of today's network information era and is a necessary path for China's teaching to become technological and modernized. Online physical education is converted from teachers and students sharing the same space to teachers and students belonging to different spaces under the conditions of epidemic prevention and control, from 3D three-dimensional teaching by word and body to 2D at teaching and physical education action skills video display through online teaching platforms (Tencent Conference APP, Tencent Classroom APP, Nail APP, and so on), from face-to-face teaching in the same place and space at the same time to live classes or prescribed time periods for learning [8][9][10][11][12].…”
