NAME
create-icfrequency.pl - This program sums the frequency counts of the CUIs from a specified set of sources in plain text.
SYNOPSIS
This program sums the frequency counts of the CUIs from a specified set of sources in plain text. The CUIs are determined by mapping the words in the text to CUIs in the UMLS using the strings in the MRCONSO table or MetaMap.
USAGE
Usage: create-icfrequency.pl.pl [OPTIONS] OUTPUTFILE INPUTFILE
OUTPUTFILE
The output file contains frequency counts for CUIs in the following format:
SAB :: (include|exclude) <sources>
REL :: (include|exclude) <relations>
N :: NUMBER
CUI<>freq
CUI<>freq
...
INPUTFILE
File containing plain text.
Optional Arguments:
--compoundify
The text contains compounds depicted by an underscore. For example, the term blood_pressure would be counted as a single term rather than blood and then pressure.
--term
Obtains the CUI counts using the term counts. This is the default.
--metamap TWO_DIGIT_YEAR
This option takes the two digit year of the version of metamap that is being used. For example, --metamap 10 would use ./metamap10 to call metamap to tag the text.
This obtains the CUI counts using MetaMap. This requires that you have MetaMap installed on your system. You can obtain this package:
These frequency counts are used to obtain the propagation counts. The format is similar to the output of count.pl from Text::NSP using the unigram option.
--config FILE
This is the configuration file. The format of the configuration file is as follows:
SAB :: <include|exclude> <source1, source2, ... sourceN>
For example, if we wanted to include on those CUIs in the MSH vocabulary:
SAB :: include MSH REL :: include RB, RN
or maybe use all the CUIs except those in MSH:
SAB :: exclude MSH
If you go to the configuration file directory, there will be example configuration files for the different runs that you have performed.
--username STRING
Username is required to access the umls database on MySql Note: if --username is specified the --password is also required.
--password STRING
Password is required to access the umls database on MySql Note: if --password is specified the --username is also required.
--hostname STRING
Hostname where mysql is located. DEFAULT: localhost
--database STRING
Database contain UMLS DEFAULT: umls
--debug
Sets the UMLS-Interface debug flag on for testing
--help
Displays the quick summary of program options.
--version
Displays the version information.
PROPAGATION
The Information Content (IC) is defined as the negative log of the probability of a concept. The probability of a concept, c, is determine by summing the probability of the concept ocurring in some text plus the probability its decendants occuring in some text:
For more information on how this is calculated please see the README file or the perldoc for create-icpropagation.pl
