Job Opening Trends

by Reginald Charney

Fuzzy Data

There was a plethora of terms found when analyzing the job-opening descriptions. For example, Windows' terms include 95, NT, CE, Win, Windows NT, etc. Besides various abbreviations, there are also ambiguous words. Is Win followed by NT to be counted as Windows and Windows NT or just Windows NT alone? Generally, the “maximum munch” rule is used. That is, the longest recognizable term possible is used. Then there are still the misspellings and unknown words. Thus, all this makes determining what is required fuzzy. Having said that, here are some of the statistics used in the job descriptions:

  • number of job openings: 129,000

  • number of unique words: 12,200

  • number of unique skill sets: 68,800

Five most often used words:

  • C++: 19,951

  • Java: 16,920

  • SQL: 9,121

  • vb: 9,003

  • HTML: 8,788

  • JavaScript: 4,793

As you would expect with all these terms, skill sets made up of a couple of words would tend to appear more often than skill sets made up of three or more words. The top five skill sets were:
  • frame relay: 445

  • Oracle dba: 445

  • C++ Java: 412

  • WinNT server: 361

  • Shell script: 361
