google generation

The University College London (UCL) CIBER group will be conducting a study for the JISC and the British Library to investigate how the Google generation searches for information and the implications for the country's major research collections. The study will try to address the following questions: - whether or not as a result of the digital transition and resources being created digitally, young people, the "Google generation", are searching for and researching content in new ways and if so, how this will shape the way they research and search in the future; - whether or not new ways of searching and researching for content will prove to be any different from the way that existing researchers/scholars work. The project comprises three main activities. The CIBER team will examine library and information science literature published over the past 30 years, including a twenty-year long survey into the research behaviour of academics as they get older. Secondly, they will analyse web logs of two online services from the BL and JISC to ascertain whether people of a variety of ages interact with them differently. Finally, a panel of industrial and technology experts will help to assess the strategic implications of the findings from the two main studies for information experts, national libraries and policy makers. Project start date: 2007-03-03. Project end date: 2007-09-30. (Excerpt from <a href="http://www.publishing.ucl.ac.uk/behaviour.html">this source</a>)

google refine

Google Refine is a standalone desktop application provided by Google for data cleanup and transformation to other formats. It has now been renamed to OpenRefine and is hosted as an opensource project on Github. It is similar to spreadsheet applications (and can work with spreadsheet file formats), however acts more like database. It operates on rows of data which have cells under columns, which is very similar to relational database tables. One Refine project is one table. User can filter rows to display using facets that define filtering criteria (for example, showing rows where given column is not empty). Unlike spreadsheets, most operations in Refine are done on all visible rows: transformation of all cells in all rows under one column, creation of new column based on existing column data, etc. All actions that were done on dataset are stored in project and can be replayed on another dataset. Unlike spreadsheets, no formulas are stored in cells, but formulas are used to transform data, and transformation is done only once. Transformation expressions are written in proprietary GREL language. Also Jython can be used to write expressions. The program has a web user interface, however it is not hosted by the software developer (SAAS), but is available for download and use on local machine. When starting Refine, it starts a web server and starts browser to open web UI powered by this webserver.

google scholar

Google Scholar is a freely accessible web search engine that indexes the full text of scholarly literature across an array of publishing formats and disciplines. Released in beta in November 2004, the Google Scholar index includes most peer-reviewed online journals of Europe and America's largest scholarly publishers. It is similar in function to the freely-available Scirus from Elsevier, CiteSeerX, and getCITED. It is also similar to the subscription-based tools, Elsevier's Scopus and Thomson ISI's Web of Science. Its advertising slogan - "Stand on the shoulders of giants" - is a nod to the scholars who have contributed to their fields over the centuries, providing the foundation for new intellectual achievements.

google search

Google Search or Google Web Search is a web search engine owned by Google Inc. and is the most-used search engine on the Web. Google receives several hundred million queries each day through its various services. The main purpose of Google Search is to hunt for text in webpages, as opposed to other data, such as with Google Image Search. Google search was originally developed by Larry Page and Sergey Brin in 1997. (Excerpt from <a href="http://en.wikipedia.org/wiki/Google_search">Wikipedia article: Google Search</a>)

google trends

Google Trends is a public web facility of Google Inc., based on Google Search, that shows how often a particular search-term is entered relative to the total search-volume across various regions of the world, and in various languages. The horizontal axis of the main graph represents time (starting from some time in 2004), and the vertical is how often a term is searched for relative to the total number of searches, globally. Below the main graph, popularity is broken down by region, city and language. It is possible to refine the main graph by region and time period. On August 5, 2008, Google launched Google Insights for Search, a more sophisticated and advanced service displaying search trends data.

google wave

Apache Wave is a software framework centered on online real-time collaborative editing, originally developed by Google as Google Wave. It was first announced at the Google I/O conference on May 27, 2009. Google Wave is a web-based computing platform and communications protocol, designed to merge key features of media like e-mail, instant messaging, wikis, and social networking. Communications using the system can be synchronous and/or asynchronous, depending on the preference of individual users. Software extensions provide contextual spelling/grammar checking, automated translation among 40 languages, and numerous other features. On August 4, 2010, Google announced the suspension of stand-alone Wave development and the intent of maintaining the web site at least for the remainder of the year. Development was handed over to the Apache Software Foundation which started to develop a server based product called Wave in a box (WIAB).

The Gopher protocol is a TCP/IP application layer protocol designed for distributing, searching, and retrieving documents over the Internet. Strongly oriented towards a menu-document design, the Gopher protocol was a predecessor of (and later, an alternative to) the World Wide Web. The protocol offers some features not natively supported by the Web and imposes a much stronger hierarchy on information stored on it. Its text menu interface is well-suited to computing environments that rely heavily on remote text-oriented computer terminals, which were still common at the time of its creation in 1991, and the simplicity of its protocol facilitated a wide variety of client implementations. Although largely supplanted by the Web in the years following, the Gopher protocol is still in use by enthusiasts, and a small population of actively-maintained servers remains.

The GNU General Public License (GNU GPL or simply GPL) is the most widely used free software license, originally written by Richard Stallman for the GNU project. The GPL is the first copyleft license for general use, which means that derived works can only be distributed under the same license terms. Under this philosophy, the GPL grants the recipients of a computer program the rights of the free software definition and uses copyleft to ensure the freedoms are preserved, even when the work is changed or added to. This is in distinction to permissive free software licenses, of which the BSD licenses are the standard examples.

A globally unique identifier or GUID is a unique reference number used as an identifier in computer software. The term GUID also is used for Microsoft's implementation of the Universally Unique Identifier (UUID) standard. The value of a GUID is often represented as a 32-character hexadecimal string, such as {21EC2020-3AEA-1069-A2DD-08002B30309D}, and is usually stored as a 128-bit integer. The total number of unique keys is 2128 or 3.4×1038 - roughly 2 trillion per cubic millimeter of the entire volume of the Earth. This number is so large that the probability of the same number being generated randomly twice is extremely small.

H.263 is a video compression standard originally designed as a low-bitrate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts Group (VCEG) in a project ending in 1995/1996 as one member of the H.26x family of video coding standards in the domain of the ITU-T. H.263 has since found many applications on the internet: much Flash Video content (as used on sites such as YouTube, Google Video, MySpace, etc.) used to be encoded in Sorenson Spark format (an incomplete implementation of H.263), though many sites now use VP6 or H.264 encoding. The original version of the RealVideo codec was based on H.263 up until the release of RealVideo 8. (Excerpt from <a href="http://en.wikipedia.org/wiki/H.263">Wikipedia article: H.263</a>)

H.264 / MPEG-4 Part 10 or AVC (Advanced Video Coding) is a standard for video compression, and is currently one of the most commonly used formats for the recording, compression, and distribution of high definition video. The final drafting work on the first version of the standard was completed in May 2003. H.264 is perhaps best known as being one of the codec standards for Blu-ray Discs; all Blu-ray players must be able to decode H.264. It is also widely used by streaming internet sources, such as videos from Vimeo, YouTube, and the iTunes Store, web software such as the Adobe Flash Player and Microsoft Silverlight, broadcast services for DVB and SBTVD, direct-broadcast satellite television services, cable television services, and real-time videoconferencing.

Apache Hadoop is an open source software framework that supports data-intensive distributed applications licensed under the Apache v2 license. It enables applications to work with thousands of computational independent computers and petabytes of data. Hadoop was derived from Google's MapReduce and Google File System (GFS) papers. Hadoop is a top-level Apache project being built and used by a global community of contributors, written in the Java programming language. Yahoo! has been the largest contributor to the project, and uses Hadoop extensively across its businesses. On February 19, 2008, Yahoo! Inc. launched what it claimed was the world's largest Hadoop production application. The Yahoo! Search Webmap is a Hadoop application that runs on more than 10,000 core Linux cluster and produces data that is now used in every Yahoo! Web search query. There are multiple Hadoop clusters at Yahoo!, and no HDFS filesystems or MapReduce jobs are split across multiple datacenters. Every hadoop cluster node bootstraps the Linux image, including the Hadoop distribution. Work that the clusters perform is known to include the index calculations for the Yahoo! search engine. On June 10, 2009, Yahoo! made available the source code to the version of Hadoop it runs in production. Yahoo! contributes back all work it does on Hadoop to the open-source community. The company's developers also fix bugs and provide stability improvements internally, and release this patched source code so that other users may benefit from their effort. In 2010 Facebook claimed that they had the largest Hadoop cluster in the world with 21 PB of storage. On July 27, 2011 they announced the data had grown to 30 PB. Besides Facebook and Yahoo!, many other organizations are using Hadoop to run large distributed computations. Some of the notable users include: (Excerpt from <a href="http://en.wikipedia.org/wiki/Apache_Hadoop">Wikipedia article: Hadoop</a>)

handle system

The Handle System is a technology specification for assigning, managing, and resolving persistent identifiers for digital objects and other resources on the Internet. The protocols specified enable a distributed computer system to store identifiers (names, or handles), of digital resources and resolve those handles into the information necessary to locate, access, and otherwise make use of the resources. That information can be changed as needed to reflect the current state and/or location of the identified resource without changing the handle. The Handle System was developed by Bob Kahn, co-inventor of the TCP/IP protocols that underlie the operation of the Internet, with support from the Defense Advanced Research Projects Agency DARPA at the Corporation for National Research Initiatives (CNRI), which continues to develop and manage it.
