'''OpenLogos''' is an open source program that translates from [[English language|English]] and [[German language|German]] into [[French language|French]], [[Italian language|Italian]], [[Spanish language|Spanish]] and [[Portuguese language|Portuguese]]. It accepts various document formats and maintains the format of the original document in translation. OpenLogos does not claim to replace human translators; rather, it aims to enhance the human translator's work environment.

The OpenLogos program is based on the Logos Machine Translation System, one of the earliest commercial [[machine translation]] programs. The original program was developed by Logos Corporation in the United States, with additional development teams in Germany and Italy.

== History ==

Logos Corporation was founded by Bernard (Bud) Scott in 1970, who worked on its Logos Machine Translation System until the company's dissolution in 2000. The project began as an English-Vietnamese translation system, which became operational in 1972 (during the American-[[Vietnam War]]), and later was developed as a multi-target translation solution, with English and German as source languages. Recently, the [[German Research Center for Artificial Intelligence]] has been working on OpenLogos, a [[Linux]]-compatible version of the original Logos program released under the [[GNU GPL]] license.

== Languages ==

Currently, OpenLogos translates from German and English into French, Italian, Spanish and Portuguese. In the long term, the goal of OpenLogos developers is to support bidirectional translation among these languages.
