The Extended Boolean Model for Information Retrieval

The Extended Boolean Model for Information Retrieval. This is an IR tutorial I wrote circa 2006 (http://www.minerazzi.com/tutorials/term-vector-6.pdf). It may be useful to those interested in learning its applicability and implementation.

The model was developed by Edward Alan Fox in his 1983 PhD thesis: Extending the Boolean and Vector Space Models of Information Retrieval with p-norm Queries and Multiple Concept Types. Ph.D. Dissertation, Cornell University. Retrieved from https://catalog.hathitrust.org/Record/009232562

The tutorial covers the advantages, limitations, and drawbacks of the model. By varying the p-norm, from p = 1 to p = infinity, its ranking behavior changes from that of a vector space-like to that of a strict Boolean-like.

I know, I know. This was posted way back at

I’m just reposting it just in case some missed this great classic model.
