May 19, 2008 -The National Transportation Safety Board (NTSB) deployed the PolyAnalyst text mining system to perform the analysis of large collections of aviation safety reports.


The NTSB is responsible for maintaining the government's database of civil aviation accidents and conducting special studies of transportation safety issues of national significance. While aviation accidents are rare, reports on thousands of minor safety incidents are collected each month. The analysis of minor incident reports can help determine and eliminate potential root causes of accidents.


To automate and simplify the analysis of aviation safety reports the NTSB acquired the text mining tool PolyAnalyst from Megaputer Intelligence. Now NTSB analysts can determine patterns and trends of safety issues, as well as probable causes of transportation incidents and accidents, through automated analysis of huge collections of incident reports.


PolyAnalyst carries out joint analysis of text and structured data, thereby enabling users to identify and visualize patterns and trends hidden in the data. Its spell checking algorithm detects possible errors and suggests corrections. The term replacement and dictionary management capabilities provide analysts with the means to utilize thesauruses capturing abbreviations, acronyms and various other semantic relationships between terms.
