Google Translate

Google Translate

translate.google.com

Google Translate is a free multilingual neural machine translation service developed by Google, to translate text and websites from one language into another. It offers a website interface, a mobile app for Android and iOS, and an application programming interface that helps developers build browser extensions and software applications. As of September 2020, Google Translate supports 109 languages at various levels and as of April 2016, claimed over 500 million total users, with more than 100 billion words translated daily.Launched in April 2006 as a statistical machine translation service, it used United Nations and European Parliament documents and transcripts to gather linguistic data. Rather than translating languages directly, it first translates text to English and then pivots to the target language in most of the language combinations it posits in its grid, with a few exceptions including Catalan-Spanish. During a translation, it looks for patterns in millions of documents to help decide on which words to choose and how to arrange them in the target language. Its accuracy, which has been criticized and ridiculed on several occasions, has been measured to vary greatly across languages. In November 2016, Google announced that Google Translate would switch to a neural machine translation engine - Google Neural Machine Translation (GNMT) - which translates "whole sentences at a time, rather than just piece by piece. It uses this broader context to help it figure out the most relevant translation, which it then rearranges and adjusts to be more like a human speaking with proper grammar". Originally only enabled for a few languages in 2016, GNMT is used in all 109 languages in the Google Translate roster as of September 2020, except for the language pair between English and Latin.

Google Books

Google Books

google.com

Google Books (previously known as Google Book Search and Google Print and by its code-name Project Ocean) is a service from Google Inc. that searches the full text of books and magazines that Google has scanned, converted to text using optical character recognition (OCR), and stored in its digital database. Books are provided either by publishers and authors through the Google Books Partner Program, or by Google's library partners through the Library Project. Additionally, Google has partnered with a number of magazine publishers to digitize their archives.The Publisher Program was first known as Google Print when it was introduced at the Frankfurt Book Fair in October 2004. The Google Books Library Project, which scans works in the collections of library partners and adds them to the digital inventory, was announced in December 2004. The Google Books initiative has been hailed for its potential to offer unprecedented access to what may become the largest online body of human knowledge and promoting the democratization of knowledge. However, it has also been criticized for potential copyright violations, and lack of editing to correct the many errors introduced into the scanned texts by the OCR process. As of October 2015, the number of scanned book titles was over 25 million, but the scanning process has slowed in American academic libraries. Google estimated in 2010 that there were about 130 million distinct titles in the world, and stated that it intended to scan all of them. As of October 2019, Google celebrated 15 years of Google Books and provided the number of scanned books as more than 40 million titles.Google Book's scanning efforts have been subject to litigation, including Authors Guild v. Google, a class-action lawsuit in the United States. This was a major case that came close to changing copyright practices for orphan works in the United States.

Encyclopædia Britannica

Encyclopædia Britannica

britannica.com

The Encyclopædia Britannica (Latin for "British Encyclopaedia") is a general knowledge English-language online encyclopaedia. It was formerly published by Encyclopædia Britannica, Inc., and other publishers (for previous editions). It was written by about 100 full-time editors and more than 4,000 contributors. The 2010 version of the 15th edition, which spans 32 volumes and 32,640 pages, was the last printed edition. The Britannica is the English-language encyclopaedia that was in print for the longest time: it lasted 244 years. It was first published between 1768 and 1771 in the Scottish capital of Edinburgh, as three volumes. (This first edition is available in facsimile.) The encyclopaedia grew in size: the second edition was 10 volumes, and by its fourth edition (1801–1810) it had expanded to 20 volumes. Its rising stature as a scholarly work helped recruit eminent contributors, and the 9th (1875–1889) and 11th editions (1911) are landmark encyclopaedias for scholarship and literary style. Starting with the 11th edition and following its acquisition by an American firm, the Britannica shortened and simplified articles to broaden its appeal to the North American market. In 1933, the Britannica became the first encyclopaedia to adopt "continuous revision", in which the encyclopaedia is continually reprinted, with every article updated on a schedule. In March 2012, Encyclopædia Britannica, Inc. announced it would no longer publish printed editions, and would focus instead on Encyclopædia Britannica Online.The 15th edition had a three-part structure: a 12-volume Micropædia of short articles (generally fewer than 750 words), a 17-volume Macropædia of long articles (two to 310 pages), and a single Propædia volume to give a hierarchical outline of knowledge. The Micropædia was meant for quick fact-checking and as a guide to the Macropædia; readers are advised to study the Propædia outline to understand a subject's context and to find more detailed articles. Over 70 years, the size of the Britannica has remained steady, with about 40 million words on half a million topics. Though published in the United States since 1901, the Britannica has for the most part maintained British English spelling.

Wikisource

Wikisource

wikisource.org

Wikisource is an online digital library of free-content textual sources on a wiki, operated by the Wikimedia Foundation. Wikisource is the name of the project as a whole and the name for each instance of that project (each instance usually representing a different language); multiple Wikisources make up the overall project of Wikisource. The project's aim is to host all forms of free text, in many languages, and translations. Originally conceived as an archive to store useful or important historical texts (its first text was the Déclaration universelle des Droits de l'Homme), it has expanded to become a general-content library. The project officially began on November 24, 2003 under the name Project Sourceberg, a play on the famous Project Gutenberg. The name Wikisource was adopted later that year and it received its own domain name. The project holds works that are either in the public domain or freely licensed; professionally published works or historical source documents, not vanity products. Verification was initially made offline, or by trusting the reliability of other digital libraries. Now works are supported by online scans via the ProofreadPage extension, which ensures the reliability and accuracy of the project's texts. Some individual Wikisources, each representing a specific language, now only allow works backed up with scans. While the bulk of its collection are texts, Wikisource as a whole hosts other media, from comics to film to audio books. Some Wikisources allow user-generated annotations, subject to the specific policies of the Wikisource in question. The project has come under criticism for lack of reliability but it is also cited by organisations such as the National Archives and Records Administration.As of October 2021, there are Wikisource subdomains active for 72 languages comprising a total of 4,957,848 articles and 2,390 recently active editors.
