Rels is a program that determines the relevance of text documents to a
set of keywords expressed in boolean infix notation. The relevance is
determined by comparing the phonetic representation of the keywords
with the phonetic representation of every word in a
document. (Phonetic searching has some degree of tolerance to
misspelled words.) The list of file names that are relevant are
printed to the standard output, in order of relevance.
For example, the command:
rel "(directory & listing)" /usr/share/man/cat1
(ie., find the relevance of all files that contain both of the words
"directory" and "listing" in the catman directory) will list 21 files,
out of the 782 catman files, (totaling 6.8 MB,) of which "ls.1" is the
fifth most relevant-meaning that to find the command that lists
directories in a Unix system, the "literature search" was cut, on
average, from 359 to 5 files, or a reduction of approximately 98%.
Although this example is remedial, a similar expediency can be
demonstrated in searching for documents in email repositories and text
archives.
Additional applications include information robots, (ie., "mailbots,"
or "infobots,") where the disposition (ie., delivery, filing, or
viewing,) of text documents can be determined dynamically, based on
the relevance of the document to a set of criteria, framed in boolean
infix notation. Or, in other words, the program can be used to order,
or rank, text documents based on a "context," specified in a general
mathematical language, similar to that used in calculators.
There is a companion application, wgetrels, which is an intelligent
Internet Web page search engine.
