# NAME

windower.pl

# SYNOPSIS

Limits the contexts of given instances to W tokens around the target word.

# USAGE

windower.pl [OPTIONS] SVAL2 W

# INPUT

## Required Arguments:

### SVAL2

SVAL2 must be a tokenized and preprocessed instance file in the Senseval-2 format.

### W

Should be a positive integer number specifying the window size. windower will display only the tokens that appear in the window of [-W, +W] centered around the target word.

## Optional Arguments:

### --plain

Output will be displayed in plain text format showing context of each instance on a single separate line. i.e. each i'th line on stdout will show the context of the i'th instance in the given SVAL2 file. By default, output is created in Senseval-2 format.

### --token TOKENREGEX

TOKENREGEX should be a file containing Perl regular expressions that define the tokenization scheme in SVAL2. windower recognizes only those character sequences from SVAL2 that match the specified token regex/s, everything else will be ignored. If --token is not specified, windower searches the default token.regex file in the current directory.

### --target TARGETREGEX

Specify a file containing Perl regular expressions that define the target word/s. Target words must be valid tokens recognizable by the specified tokenization scheme (via --token or token.regex)

Following are some of the examples of TARGET word regex files -

/<head>[Ll]ines?<\/head>/

which specifies that the target word could be

     line, Line, lines or Lines

delimited in <head> and </head> tags.

Above regex can also be specified as multiple regexes in TARGET as -

/<head>line<\/head>/

/<head>lines<\/head>/

/<head>Line<\/head>/

/<head>Lines<\/head>/

with a single regex per line

Regex

/<head>\w+<\/head>/

shows a more general regex for target words marked in <head> tags

Regex

/<head.*>\w+<\/head>/

Shows the regex for matching target words in the original Senseval-2 data.

/[Ll]ines?/

shows that any occurrence of words - Line, line, Lines, lines are target words (that are not delimited in any special tags).

### Other Options :

#### --help

Displays this message.

#### --version

Displays the version information.

# OUTPUT

When --plain is not selected, OUTPUT is in Senseval-2 format that looks same as the input SVAL2 file except the context of each instance shows atmost W words around the target word.

When --plain is ON, OUTPUT shows each context on a single line i.e. context of i'th instance in the given SVAL2 file is shown on the i'th line on stdout.
