NAME

maketarget.pl

SYNOPSIS

Creates a Perl regex for the TARGET word by detecting its various forms from the given SVAL2 file.

DESCRIPTION

This program will create a regular expression file called target.regex that can be used to match target words via the --target option in many SenseClusters programs. The target.regex file can be of two forms:

 /<head>\s*(target1|target2)\s*</head>/

or

 /(\btarget1\b)|(\btarget2\b)/

The first form is appropriate when the corpus already has the target word marked with head tags, while the second should be used when the corpus is plain unannotated text. The second form is the default, while the first is available with the --head option. Note that in the first form the <head> tag acts as a delimiter on word boundaries, while in the second form the \b character class is used for that purpose.

USAGE

maketarget.pl [OPTIONS] SVAL2

INPUT

Required Arguments:

SVAL2

Should be a file in Senseval-2 format from which various possible forms of the TARGET word are to be detected.

Optional Arguments:

--head

Create target word regex in the form: <head>\s*(target1|target2)\s*</head>

--help

Displays the summary of command line options.

--version

Displays the version information.

OUTPUT

maketarget.pl automatically creates the file with name 'target.regex' that shows the Perl regex for the TARGET word. The regex is a OR of various forms of the word detected placed within a single regex, optionally surrounded by <head> and </head> tags.

For example: Contents of a sample <target.regex> file:

 /(\bLine\b)|(\bLines\b)|(\bline\b)|(\blined\b)|(\blines\b)/ (default)

 /<head>\s*(Line)|(Lines)|(line)|(lined)|(lines)\s*</head>/ (with --head)

BUGS

This program does not recognize target words of the form:

 <head> Bill Clinton </head>

It is restricted to target words that are a single string, such as

 <head> Bill_Clinton </head>
