[CHaracter Ocr COordination for MUFI iN texts] A simple script to maintain a reasonable training set of HTR/OCR characters

Choco-Mufin

[CHaracter Ocr COordination for MUFI iN texts]

Tools for normalizing the use of some characters and checking file consistencies. Mainly target at dealing with overly diverse ways to transcribe medieval data (allographetic and graphematic for example) while keeping information such as abbreviation, hence MUFI.

Install

pip install chocomufin

Commands

The workflow is generally the following: you generate a conversion table (chocomufin generate table.csv your-files.xml), then use this table to either control (chocomufin control table.csv your-files.xml) or convert them (chocomufin convert table.csv your-files.xml). Conversion will automatically add a suffix which you can define with --suffix.

Table of conversion

Syntax

A conversion table MUST contain at least a char and a replacement column, SHOULD contain a regex and allow column (with either true or empty values), and MAY contain any additional column.

The columns have the following effect:

• char is used to match a value in the XML or the text.
• replacement is used to replace what was found in char.
• regex, if true, means char and replacement should be parsed as regex.
• allow, if true, will indicate that replacement should be ignored, and that the value(s) in char are valid.

Any other column should be seen as a comment.

Example

In the following table:

lineno,char,replacement,regex,allow
1,V,U,,
2,[a-ik-uw-zA-IK-UW-Z],,true,true
3,(\S)(\.)(\S),\g<0>\g<1> \g<2>,true,
4,_,,,true

• Line no. 1 will replace any V into a U;
• Line no. 2 will allow any character in the range defined: those characters won't be replaced and will be accepted as is.
• Line no. 3 will replace any dot without spaces around it with a regex replacement groups used in the regex.
• Line no. 4 will allow _ in the text, and not replace it with anything.

As table:

lineno	char	replacement	regex	allow
1	V	U
2	[a-ik-uw-zA-IK-UW-Z]		true	true
3	(\S)(.)(\S)	\g<1>\g<2> \g<3>	true
4	_			true

In this context, lineno is not used at all by chocomufin, but serves as a documentation tool. It would not break chocomufin.

Github Action Template

Just replace the path to table.csv and the file that needs to be tested, then save this file on your repository in .github/workflows/chocomufin.yml:

# This workflow will install Python dependencies, run tests and lint with a single version of Python
