Computer linguistics expert witness candidates typically have a background in natural language processing, artificial intelligence, speech recognition, computer science, and/or machine learning. The chosen expert may be a member of an industry association such as the Association for Computational Linguistics (ACL). A computational linguistic specialist needs to not only have expertise, but must also possess the ability to provide expert testimony in such a manner that jurors can understand the linguistic evidence.
Computational linguistics draws upon linguistics, computer science, artificial intelligence, mathematics, logic, philosophy, cognitive science, cognitive psychology, psycholinguistics, anthropology and neuroscience. As defined by ACL, computational linguistics is:
“the scientific study of language from a computational perspective … the work of computational linguists is incorporated into many working systems today, including speech recognition systems, text-to-speech synthesizers, automated voice response systems, web search engines, text editors, language instruction materials, to name just a few.”
Computer linguistics matters that require technical expertise typically involve intellectual property, such as a patent litigation or a trade secret dispute. Litigation support by a computer linguistics expert witness could include expert report preparation, expert opinion, and expert witness testimony at a trial. In addition, clients may seek a computer linguistics industry expert for pre-litigation consulting work.
