A METHOD OF CONSTRUCTION INFORMATION MANAGEMENT SYSTEM WITH USING BIG DATA PROCESSING

摘要

The present invention utilizes a big data scraping technology, a data collection step of collecting data from a source document including one or more of a quantity calculation statement, a statement, and a milestone into structured-unstructured data composed of natural language, and a big data crawling text conversion technology Using the data processing step of converting the extracted data into a structured data format and processing it in the form of information required for information construction, and using the construction information standard classification system for each of the lowest data collected and processed from the source information, the upper information in the data cube Data building for big data construction consisting of 5W1H multi-dimensional information structure of automatic mapping stage and 5W1H multidimensional information structure of who (WHO), when (WHEN), where (WHERE), what (WHAT), how (HOW), and what method (WHY) It provides a method of using a construction project information management system based on big data including steps, OLAP, Query Optimizer utilization, multi-perspective & LoD information extraction, and data mining module for high-speed operation.
