CaMS Seminar Series kicks off with “How Web Search Works”

Published: September 14, 2015.

Dr. Ray Klump, professor and chair of Computer and Mathematical Sciences at Lewis University, gave the first presentation for this year’s CaMS (Computer and Mathematical Sciences) Seminar Series titled, “How Web Search Works.”

Klump explained computer science is about more than hardware and software, “Computer science is best when it deals in ideas.”

During the seminar, Klump discussed that web search is something everyone takes for granted and only a few know how it works behind the scenes. He enlightened his audience describing web search as a combination of indexing, matching, and ranking. He also discussed:

  • the importance of algorithms,

  • how the KISS principle applies to the efficiency of web search,

  • the history of search engines,

  • Google’s “money maker,”

  • how word-location indexing maps works,

  • issues with cycles,

  • and the types of strategies PageRank uses.

The series is scheduled to continue two Tuesdays per month at 3:30 p.m . Visit to watch the archived presentations.
