Colossal Clean Crawled Corpus
Common Crawl is a nonprofit 501(c)(3) organization that crawls the web and freely provides its archives and datasets to the public. Common Crawl's web archive consists of petabytes of data collected since 2008. It completes crawls approximately once a month. Common Crawl was founded by Gil Elbaz. Advisors to the non-profit include Peter Norvig and Joi Ito. The organization's crawlers respect nofollow and robots.txt policies. Open source code for processing Common Crawl's data set is publicly available. The Common Crawl dataset includes copyrighted work and is distributed from the US under fair use claims. Researchers in other countries have made use of techniques such as shuffling sentences or referencing the Common Crawl dataset to work around copyright law in other legal jurisdictions. Contents archived by Common Crawl are mirrored and made available online in Wayback Machine. English is the primary language for 46% of documents in the March 2023 version of the Common Craw ...

Jurisdiction
Jurisdiction (from Latin 'law' and 'speech' or 'declaration') is the legal term for the legal authority granted to a legal entity to enact justice. In federations like the United States, the concept of jurisdiction applies at multiple levels (e.g., local, state, and federal). Jurisdiction draws its substance from international law, conflict of laws, constitutional law, and the powers of the executive and legislative branches of government to allocate resources to best serve the needs of society. International dimension Generally, international laws and treaties provide agreements which nations agree to be bound to. Such agreements are not always established or maintained. Extraterritorial jurisdiction is exercised through three principles outlined in the UN charter. These are equality of states, territorial sovereignty and non-intervention. This raises questions of when can many states prescribe or enforce jurisdiction. The ''Lotus'' case establishes two key rules t ...

Benelux
The Benelux Union (; ; ; ) or Benelux is a politico-economic union, alliance and formal international intergovernmental cooperation of three neighbouring states in Western Europe: Belgium, the Netherlands, and Luxembourg. The name is a portmanteau formed from joining the first few letters of each country's name and was first used to name the customs agreement that initiated the union (signed in 1944). It is now used more generally to refer to the geographic, economic, and cultural grouping of the three countries. The Benelux is an economically dynamic and densely populated region, with 5.6% of the European population (29.55 million residents) and 7.9% of the joint EU GDP (€36,000/resident) on 1.7% of the whole surface of the EU. In 2015, 37% of the total number of EU cross-border workers worked in the Benelux; 35,000 Belgian residents work in Luxembourg, while 37,000 others cross the border to work in the Netherlands each day. In addition, 12,000 Dutch and close to a thous ...

Tebibyte
The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol () refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The size of the byte has historically been hardware-dependent and no definitive standards existed that mandated the size. Sizes from 1 to 48 bits have been used. The six-bit character code was an often-used implementation in early encoding systems, and computers using six-bit and nine-bit bytes were common in the 1960s. These systems often had memory words of 12, 18, 24, 30, 36, 48, or 60 bits, corresponding to ...

GPT-3
Generative Pre-trained Transformer 3 (GPT-3) is a large language model released by OpenAI in 2020. Like its predecessor, GPT-2, it is a decoder-only transformer model of deep neural network, which supersedes recurrence and convolution-based architectures with a technique known as "attention". This attention mechanism allows the model to focus selectively on segments of input text it predicts to be most relevant. GPT-3 has 175 billion parameters, each with 16-bit precision, requiring 350GB of storage since each parameter occupies 2 bytes. It has a context window size of 2048 tokens, and has demonstrated strong " zero-shot" and " few-shot" learning abilities on many tasks. On September 22, 2020, Microsoft announced that it had licensed GPT-3 exclusively. Others can still receive output from its public API, but only Microsoft has access to the underlying model. Background According to ''The Economist'', improved algorithms, more powerful computers, and a recent increase i ...

Web ARChive
The WARC (Web ARChive) archive format specifies a method for combining multiple digital resources into an aggregate archive file together with related information. These combined resources are saved as a WARC file which can be replayed using appropriate software such as ReplayWeb.page, or used by archive websites such as the Wayback Machine. The WARC format is a revision of the Internet Archive's ARC_IA File Format that has traditionally been used to store " web crawls" as sequences of content blocks harvested from the World Wide Web. The WARC format generalizes the older format to better support the harvesting, access, and exchange needs of archiving organizations. Besides the primary content currently recorded, the revision accommodates related secondary content, such as assigned metadata, abbreviated duplicate detection events (see §7.6 "revisit"), and later-date transformations. The WARC format is inspired by HTTP/1.0 streams, with a similar header and the use of CRLFs as ...

Nutch
Apache Nutch is a highly extensible and scalable Open-source license, open source web crawler software project. Features Nutch is coded entirely in the Java (programming language), Java programming language, but data is written in language-independent formats. It has a highly modular architecture, allowing developers to create plug-ins for media-type parsing, data retrieval, querying and clustering. The fetcher ("robot" or "web crawler") has been written from scratch specifically for this project. History Nutch originated with Doug Cutting, creator of both Lucene and Hadoop, and Mike Cafarella. In June, 2003, a successful 100-million-page demonstration system was developed. To meet the multi-machine processing needs of the crawl and index tasks, the Nutch project has also implemented the MapReduce project and a distributed file system. The two projects have been spun out into their own subproject, called Hadoop. In January, 2005, Nutch joined the Apache Incubator, from whi ...

Search Engine Optimization
Search engine optimization (SEO) is the process of improving the quality and quantity of Web traffic, website traffic to a website or a web page from web search engine, search engines. SEO targets unpaid search traffic (usually referred to as "Organic search, organic" results) rather than direct traffic, referral traffic, social media traffic, or Online advertising, paid traffic. Unpaid search engine traffic may originate from a variety of kinds of searches, including image search, video search, academic databases and search engines, academic search, news search, and industry-specific vertical search engines. As an Internet marketing strategy, SEO considers how search engines work, the computer-programmed algorithms that dictate search engine results, what people search for, the actual search queries or Keyword research, keywords typed into search engines, and which search engines are preferred by a target audience. SEO is performed because a website will receive more visito ...

Blekko
Blekko (trademarked as blekko) was a company that provided a web search engine with the stated goal of providing better search results than those offered by Google Search, with results gathered from a set of 3 billion trusted webpages and excluding such sites as content farms. The company's site, launched to the public on November 1, 2010, used slashtags to provide results for common searches. Blekko also offered a downloadable search bar. It was acquired by IBM in March 2015, and the service was discontinued."Blekko: The Newest Search Engine" ''PC Magazine'', November 1, 2010. Accessed November 1, 2010. Blekko also differentiated itself by offering richer data than its competitors. For instance, if a user accessed a domain name with the added ''/seo'', he would be directed to a page containing the statistics of the URL. This is the reason experts cited Blekko's fitness with the Big Data paradigm since it gathers multiple data sets and presents them visually so that the user is ...

Heritrix
Heritrix is a web crawler designed for web archiving. It was written by the Internet Archive. It is available under a free software license and written in Java (programming language), Java. The main interface is accessible using a web browser, and there is a command-line tool that can optionally be used to initiate crawls. Heritrix was developed jointly by the Internet Archive and the Nordic national libraries on specifications written in early 2003. The first official release was in January 2004, and it has been continually improved by employees of the Internet Archive and other interested parties. For many years Heritrix was not the main crawler used to crawl content for the Internet Archive's web collection. The largest contributor to the collection, as of 2011, is Alexa Internet. Alexa crawls the web for its own purposes, using a crawler named ''ia_archiver''. Alexa then donates the material to the Internet Archive. The Internet Archive itself did some of its own crawling us ...
