- 🎯 First round response: The answer to your question is: When training an Arabic recognition model and creating a customized Arabic dictionary, there are several best practices to consider.
Regarding the changing shapes of Arabic letters, such as the letter alif having 4 forms with different unicode glyphs, you have two options. You can either include all possible shapes of the letter in the dictionary or include a single letter in the alphabet. If you choose to include a single letter, the model can still be trained to recognize different shapes of the same letter through a 1-to-many mapping. The model is capable of handling this mapping.
Since Arabic is a cursive language and letters merge together when joined, known as ligature, it is important to take this into account when creating the dictionary. The dictionary should include ligature forms of the letters to ensure accurate recognition.
As for the order of paddleOCR recognition, it is important to note that Arabic is a right-to-left language. If paddleOCR reads texts from left to right, you should be concerned. However, the provided text does not specify any files that need to be changed to address this concern.
In summary, when training an Arabic recognition model and creating a customized Arabic dictionary, you can include all possible shapes of Arabic letters or use a single letter with a 1-to-many mapping. The dictionary should also include ligature forms of the letters. As for the order of paddleOCR recognition, further clarification is needed on whether any files need to be changed to accommodate the right-to-left nature of Arabic.

Let's say I want to train an Arabic recognition model, what's the best practice when creating a customized Arabic dictionary?\nNow, there are several things that make it challenging:\nArabic letters change their shapes depending on their locations in the word, for example, the letter alif has 4 forms and each one has a unicode glyph. Should I include all possible shapes of it in the dictionary or should I just include a single letter in the alphabet?\nfollow-up on 1, if I only include a single letter, then how is the model trained such that it can recognize different shapes of the same letter? It sounds like a 1-to-many mapping, can the model do that?\nArabic is cursive, that means when joining letters together, they merge together, which is called ligature. How can I take this into account when creating the dictionary?\nWhat's the order of paddleOCR recognition? Because Arabic is a right-to-left language, and if paddleocr reads texts from left to right, should I be concerned and are there any files that I should change?
