Text::Names - Perl extension for proper name parsing, normalization, recognition, and classification
use Text::Names qw/parseNames samePerson/; my @authors = parseNames("D Bourget, Zbigniew Z Lukasiak and John Doe"); # @authors = ('Bourget, D.','Lukasiak, Zbigniew Z.','Doe, John') print "same!" if samePerson("Dave Bourget","David F. Bourget"); # same! print guessGender("David"); # "M"
This modules provides a number of name normalization routines, plus high-level parsing and name comparison utilities such as those illustrated in the synopsis.
While it tries to accommodate non-Western names, this module definitely works better with Western names, especially English-style names.
No subroutine is exported by default.
This modules normalizes names to this format:
Lastname(s) [Jr], Given name(s)
1) Bourget, David Joseph Richard
2) Bourget Jr, David
3) Bourget, D. J. R.
These are all normalized names. This format is what is referred to as the normalized representation of a name here.
Returns true iff name1 is a common abbreviation of name2 in English. For example, 'Dave' is a common abbreviation of 'David'. The list of abbreviations used includes a number of old abbreviations such as 'Davy' for 'David'.
Like parseName, but a) returns the normalized form of the name instead of an array, and b) does additional cleaning-up. To be prefered to parseName in most cases and by default if processing variable or dubious data.
Returns the name in the "last, given" format.
Returns true if the name is among the 1000 most popular firstnames (male or female) according to the 1990 US Census. If a threshold percentage is passed, the name must have at least this frequency for the subroutine to return true. See http://www.census.gov/genealogy/www/data/1990surnames/names_files.html.
Returns true if the name is among the 1000 most popular surnames according to the 1990 US Census. If a threshold percentage is passed, the name must have at least this frequency for the subroutine to return true. See http://www.census.gov/genealogy/www/data/1990surnames/names_files.html.
Normalizes the whitespace within a name. This is mainly for internal usage.
Takes a name in one of the multiple formats that one can write a name in, and returns it as an array representing the post-comma and pre-comma parts of its normalized form (in that order). For example, parseName("David Bourget") returns ('David','Bourget').
Use on already-normalized names to split them into four parts: full given names, initials, last names, and suffix. The only 'suffix' recognied is 'Jr'.
Takes an array of names (as strings) and returns an array of normalized representations of the names in the array.
Takes a string of names as parameter and returns an array of normalized representations of the names in the string. This routine understands a wide variety of formattings for names and lists of names typically found as list of authors in bibliographic citations. See the test 03-parseNames.t for multiple examples.
Given a normalized name of the form "last, given", returns "given last".
Returns a true value iff name1 and name2 could reasonably be two writings of the same name. For example, 'D J Bourget' could reasonably be a writing of 'David Joseph Bourget'. So could 'D Bourget'. But 'D F Bourget' is not a reasonable writing of 'David Joseph Bourget'. The value returned is a (potentially new) name string which combines the most complete tokens of the two submitted name strings.
Contrary to what one might expect, this subroutine does not use weakenings() behind the scenes. Another way to check for name compatibility would be to check that two names have a weakening in common (probably too permissive for most purposes) or that one name is a weakening of the other.
Sets the abbreviation mapping used to determine whether, say, 'David' and 'Dave' are compatible name parts. The mapping is also used by abbreviationOf(). The format of the array should be: 'Dave', 'David', 'Davy', 'David', etc, otherwise representable in Perl as 'Dave' => 'David', 'Davy' => 'David', etc.
Returns an array of normalized names which are weakenings of the name passed as argument. Substituting a given names by an initial, or removing an initial, for example, are operations which generate weakenings of a name. Such operations are applied with arbitrary depth, until the name has been reduced to a single initial followed by the lastname, and all intermediary steps returned.
Returns 'F' if someone with the provided firstname is likely female, 'M' if likely male, and undef otherwise. A frequency threshold (default = 0) can be specified so that a gender is returned only if the name is found with at least this frequency among people with this gender (according to the US census). A threshold of 0.1 (which means 0.1%) ensures very reliable results (precision above 99%) with a recall of about 60%. When the threshold is lower, this function has a tendency to overestimate the number of females.
None by default.
This module currently overwrites @Text::Capitalize::exceptions globally, which can have unintended side-effects.
