This is a command-line tool. It reads ASCII text from the specified files (or its standard input), and will print on the standard output lines that (probably) match a Greek surname. Various command-line options can direct the matching to be performed on specified fields or the longest part of a field.

Installation

Run make install

Execution

The classifier requires two files containing n-grams derived from large collections of Greek and international surnames. Therefore, run it from the directory containing the source code (as perl greek-classifier.pl), or install it in order to run it from any directory (as greek-classifier).

Example

perl greek-classifier.pl highly-cited-cs-all.txt
ALAMOUTI
ALEXOPOULOS
CURTIS
DENNIS
KOMLOS
PAPADIMITRIOU
POLYDOROS
TRIVEDI
VALIANT
VARANASI
VARDI
VAZIRANI
VOLAKIS
YANNAKAKIS

Command-line options

greek-classifier [-d distance] [-k field] [-l] [-t separator] [file ...]
greek-classifier -g [file ...]
-d distance     Specify the distance that generates a match (default 9)
                Higher values increase precision (fewer wrong entries)
                Lower values increase recall (fewer missed entries)
-D              Print the calculated distances
-g              Generate an n-gram table
-k field        Specify field to match; first is 1 (default whole line)
-l              Match only line's / field's longest word
-t separator    Specify field separator RE (space characters by default)
-u              Normalize matched part to uppercase
-w              Print matching word, rather than matching line

Performance

These are the classifier's performance metrics, as reported by the script evaluate.sh

• Precision: .94
• Recall: .86
• Specificity: .97
• Accuracy: .94
• MCC: .86

Use case

The Python 3 script greek-scientists.py is a small CGI web application that queries the DBLP bibliographic database for Greek scientists who have published in a given venue over a specific period.
