This paper presents a method for structuring a machine-readable version of the Arabic-English Al-Mawrid dictionary, addressing the lack of standardization in printed formats. The approach converts unstructured streams of words and punctuation into explicit hierarchical structures that define entry components such as subentries, domain labels, and translation equivalences. Parsing serves as the central step within a cascaded design, implemented using the parsing expression grammars formalism. This technique allows for the automatic or semi-automatic organization of dictionary entries despite the absence of microstructure standardization in Arabic dictionaries. The study demonstrates that inducing microstructure enables plausible accuracy in structuring these complex lexical resources. By transforming raw text into defined formats, the work supports downstream natural language processing applications requiring machine-readable lexical data.
