## 2 Background
### Machine Translaters
The tool provides an API [30] that facilitates machine-to-machine communication, enabling automation through scripts for text input and retrieval. In terms of input formats, E-Translation supports a wide range, with a daily limit of 100 documents and a character limit of 2500 for individual text submissions. Translation outputs are generated in text format, and translated files are provided in.dox format. The tool does not allow direct modifications to its translation models or customizable programming versions. E-Translation is trained on various sources, including EU documents, translation memories, and publicly available multilingual texts. While these corpora cannot be modified, public entities may request adjustments in specific cases. The tool receives periodic updates to enhance its functionality and accuracy. Pangeanic [31] is a translation tool developed by the company of the same name. It does not support multitasking, as it cannot handle multiple translation tasks simultaneously. However, Pangeanic offers an API that enables automation for inputting and retrieving translated texts. The tool supports a wide variety of input formats, generating translation outputs in both text and document formats. Unlike some competitors, Pangeanic does not allow direct modifications to its translation models or provide user-programmable versions. However, it offers specialized dictionaries, allowing for limited customization. The tool utilizes proprietary specialized dictionaries for translation, though the exact sources of its data are not explicitly disclosed. Operating exclusively online, Pangeanic is classified as a generalist translation tool, though it offers the possibility of specialization through domain-specific corpora provided by the company. While the update frequency is not explicitly stated, Pangeanic regularly releases updates to enhance service quality and functionality. Additionally, its API provides a fast and efficient solution for machine translation, allowing users to integrate translation capabilities directly into their content management systems. Systran [23] is an advanced artificial intelligence tool developed by Changvision, designed with multitasking capabilities that allow multiple translation tasks to be processed simultaneously. The platform provides an API with two modes: a free version with a 500,000-character limit and a professional version priced at EUR 8.99 per month with no volume restrictions. Through the Systran API and automation scripts, users can efficiently input text for translation and retrieve results. The tool supports a wide range of input formats and document types, each with specific size limitations depending on the format. Translation results are generated in JSON format when using the API for both text and document translations. Notably, Systran allows customization and modification of its translation models through its Profiles API [32], enabling the integration of specific corpora or dictionaries for domain-specific translations. The tool operates exclusively online and is updated periodically to improve functionality and accuracy. Reverso [24], developed by Softissimo INC, is an artificial intelligence tool specializing in translation and natural language processing. Unlike general-purpose multitasking tools, Reverso is designed to provide precise translations alongside complementary linguistic tools tailored for individual and professional users. While Reverso does not officially offer a public API, community-developed tools and APIs are available [33], though their usage may be subject to restrictions imposed by the Reverso team. The platform does not support automation for inputting and retrieving translated texts, thereby limiting its integration with advanced automation systems. It accommodates a wide range of input formats, with translation outputs available in plain text and.docx formats. However, Reverso does not permit direct modifications within the platform, nor does it provide programmable versions for user-driven customizations.
