2	Prof. Abdulmajid Ahmed Ghalib Al-Khulaidi	Main supervisor	Sana’a University	Member
3	Prof. Muneer Abdullah Saeed Hazaa Al-Mekhlafi	External Examiner	Thamar University	Chair

The dissertation aimed to improve the retrieval of Arabic text from documents.

The dissertation concluded with several key findings, including:

Inventing a method to generate a large database of Arabic words and their roots based on morphology.
Using the generated data to train a BiLSTM RNN model for recognizing Arabic word roots.
Testing the proposed model’s ability to recognize the true root and improve data classification against seven previous methods.

The candidate also presented several recommendations and future research gaps, such as the potential use of the word generation method for other problems, including question answering.

The PhD dissertation was examined and recommended by the Viva-Voce Committee for acceptance and approval. The PhD defense was attended by a number of academics, researchers, interested students, the candidate’s colleagues, and family members.
