Latest Patents

Al-Khatib's latest patents include an innovative Arabic spell checking error model. This model is data-driven and focuses on error patterns found at the morphemes level. It generates a model through an error-correct patterns generator, which is stored in an error-correct patterns database (ECPD). The ECPD works alongside a correction candidates' generator (CCG) to provide a list of correction candidates for any given error word. This error model is capable of learning various types and forms of language patterns from an annotated corpus, allowing it to analyze errors and suggest corrections for a wide range of Arabic spelling mistakes.

Another significant patent is a method for the retrieval of Arabic historical manuscripts. This method employs Latent Semantic Indexing (LSI) to address the challenges of indexing and retrieving Arabic historical manuscripts. It automates the indexing process through word spotting, utilizing 'Text Image' similarity of keywords. The method includes several steps: manuscript page preprocessing, segmentation, and feature extraction, which uses a circular polar grid feature set. After extracting salient features, the indexing of historical Arabic manuscripts is performed using LSI to support content-based image retrieval (CBIR).
