Attributing an anonymous text to its author has become an important issue in modern forensic linguistics. Researchers employ stylistic analysis, statistical analysis, and corpus linguistics in this field. An anonymous text can be compared with a collection of known texts written by a suspect, followed by an examination of similarities and differences in: Vocabulary. Sentence length. Syntactic structures. Punctuation marks. Recurring errors. Function words. Expressive style. Fifth: The Role of Computational Linguistics and Artificial Intelligence The field of authorship identification has witnessed significant development as a result of the use of computational tools, corpus analysis, and natural language processing techniques. Recent research has included specialized efforts to identify the authors of texts written in the Arabic script, using computational methods to compare different writing patterns. Recent studies have also begun to investigate the use of artificial intelligence models to identify the authors of Arabic forensic texts. This trend may open new opportunities for developing supporting tools for investigators and forensic experts. However, the use of artificial intelligence does not mean replacing the linguistic expert. Computational results require scientific interpretation and human review, particularly in cases involving legal responsibility. Sixth: The Importance of Linguistic Evidence in Criminal Investigation The analysis of linguistic evidence can contribute to: Assisting in identifying the author of an anonymous text. Analyzing threatening and extortion messages. Examining anonymous posts on social media. Identifying the dialectal characteristics of a speaker. Comparing texts attributed to the same individual. Analyzing confessions and statements. Detecting stylistic similarities between texts. Supporting other forms of forensic evidence. Specialized studies emphasize that the value of linguistic evidence increases when it is considered as part of an integrated body of evidence rather than being relied upon independently. Seventh: Challenges Facing Forensic Linguistic Analysis Despite the importance of this field, it faces a number of challenges, including: The diversity of Arabic dialects. Similarities between the writing styles of different individuals. The possibility that a suspect may deliberately alter their writing style. The use of pseudonyms and fake accounts. The use of artificial intelligence programs to generate texts. The limited availability of specialized Arabic forensic linguistic corpora. The difficulty of distinguishing accidental similarities from similarities that indicate common authorship. The need to take the social and cultural context of the text into consideration. Conclusion This study demonstrates that language can play an important role within the framework of forensic evidence, particularly in cases where written texts or spoken discourse constitute part of the criminal event. The analysis of criminal discourse has become an interdisciplinary field that connects linguistics with forensic, legal, and computational sciences, thereby creating new opportunities for the development of scientific investigative methods. The importance of this field is particularly evident in the digital environment, where cybercrimes leave behind a large amount of texts, correspondence, comments, and posts that can be subjected to linguistic analysis. Therefore, developing Arabic forensic linguistics, establishing specialized linguistic corpora, and training experts in the analysis of Arabic texts and dialects can contribute to enhancing the use of language as a source of forensic evidence. [10/5/2026 11:03 AM] سراب عباس جاسم: Results The study reached a number of conclusions, the most important of which are: [10/5/2026 11:06 AM] هويدا نزال حسين: Language can constitute an important source of evidence in certain criminal cases. Linguistic analysis operates at several levels, including lexical, syntactic, semantic, pragmatic, and stylistic analysis. Electronic messages and anonymous posts represent an important field for the application of forensic linguistics. Dialectal features can provide useful indicators, but they are not sufficient on their own to establish the identity of the author. Corpus analysis and computational tools contribute to the development of authorship identification. Linguistic evidence should be integrated with other forms of forensic evidence in order to achieve more reliable conclusions.
