Facemark Detection

This model classifies given text into facemark(1) or not(0).

This model is a fine-tuned version of cl-tohoku/bert-base-japanese-whole-word-masking on an original facemark dataset. It achieves the following results on the evaluation set:

Model description

This model classifies given text into facemark(1) or not(0).

Intended uses & limitations

Extract a facemark-prone potion of text and apply the text to the model. Extraction of a facemark can be done by regex but usually includes many non-facemarks.

For example, I used the following regex pattern to extract a facemark-prone text by perl.

$input_text = "facemark prne text"

my $text          = '[0-9A-Za-zぁ-ヶ一-龠]';
my $non_text      = '[^0-9A-Za-zぁ-ヶ一-龠]';
my $allow_text    = '[ovっつ゜ニノ三二]';
my $hw_kana       = '[ｦ-ﾟ]';
my $open_branket  = '[\(∩꒰（]';
my $close_branket = '[\)∩꒱）]';
my $around_face   = '(?:' . $non_text . '|' . $allow_text . ')*';
my $face          = '(?!(?:' . $text . '|' . $hw_kana . '){3,8}).{3,8}';
my $face_char     = $around_face . $open_branket . $face . $close_branket . $around_face;

my $facemark;
if ($input_text=~/($face_char)/) {
  $facemark = $1; 
}

Example of facemarks are:

This model intended to use for a facemark-prone text like above.
