Browse All Lyrics Alphabetically
Browsing is a kind of orienting strategy. It is supposed to identify something of relevance for the browsing organism. When used about human beings it is a metaphor taken from the animal kingdom. It is used, for example, about people browsing open shelves in libraries, window shopping, or browsing databases or the Internet. In library and information science it is an important subject, both purely theoretically and as applied science aiming at designing interfaces which support browsing activities for the user. Definition Hjørland (2011b) provided the following definition: "Browsing is a quick examination of the relevance of a number of objects which may or may not lead to a closer examination or acquisition/selection of (some of) these objects. It is a kind of orienting strategy that is formed by our "theories", "expectations" and "subjectivity". Controversies As with any kind of human psychology, browsing can be understood in biological, behavioral, or cognitive terms ...

Information Behavior
Information behavior is a field of information science research that seeks to understand the way people search for and use information in various contexts. It can include information seeking and information retrieval, but it also aims to understand why people seek information and how they use it. The term 'information behavior' was coined by Thomas D. Wilson in 1981 and sparked controversy upon its introduction. The term has now been adopted and Wilson's model of information behavior is widely cited in information behavior literature. In 2000, Wilson defined information behavior as "the totality of human behavior in relation to sources and channels of information". A variety of theories of information behavior seek to understand the processes that surround information seeking. An analysis of the most cited publications on information behavior during the early 21st century shows its theoretical nature. Information behavior research can employ various research methodologies grou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Browser
A web browser is application software for accessing websites. When a user requests a web page from a particular website, the browser retrieves its files from a web server and then displays the page on the user's screen. Browsers are used on a range of devices, including desktops, laptops, tablets, and smartphones. In 2020, an estimated 4.9 billion people used a browser. The most used browser is Google Chrome, with a 65% global market share on all devices, followed by Safari with 18%. A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website's server and display its web pages, a user must have a web browser installed. In some technical contexts, browsers are referred to as user agents. Function The purpose of a web browser is to fetch content from the World Wide Web or from local storage and display it on a user's device. This process ...

Skimming (reading)
Speed reading is any of many techniques claiming to improve one's ability to read quickly. Speed-reading methods include chunking and minimizing subvocalization. The many available speed-reading training programs may utilize books, videos, software, and seminars. There is little scientific evidence regarding speed reading, and as a result its value seems uncertain. Cognitive neuroscientist Stanislas Dehaene says that claims of reading up to 1,000 words per minute "must be viewed with skepticism". History The term "speed reading" is thought to have been coined in the late 1950s by Evelyn Wood, a schoolteacher. She was reportedly curious why some people were naturally faster at reading, so tried to force herself to read very quickly. In 1958, while brushing off the pages of a book she had thrown, she noticed that the sweeping motion of her hand across the page caught the attention of her eyes, and helped them move more smoothly across the page. She then used the hand as a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Serendipity
Serendipity is an unplanned fortunate discovery. Serendipity is a common occurrence throughout the history of product invention and scientific discovery. Etymology The first noted use of "serendipity" was by Horace Walpole on 28 January 1754. In a letter he wrote to his friend Horace Mann, Walpole explained an unexpected discovery he had made about a lost painting of Bianca Cappello by Giorgio Vasari by reference to a Persian fairy tale, ''The Three Princes of Serendip''. The princes, he told his correspondent, were "always making discoveries, by accidents and sagacity, of things which they were not in quest of." The name comes from ''Serendip'', an old Persian name for Sri Lanka (Ceylon), hence ''Sarandib'' by Arab traders. It is derived from the Sanskrit ''Siṃhaladvīpaḥ'' (Siṃhalaḥ, Sri Lanka + dvīpaḥ, island). The word has been exported into many other languages, with the general meaning of "unexpected discovery" or "fortunate chance". Applications Inventio ...

Optimal Foraging
Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. Although obtaining food provides the animal with energy, searching for and capturing the food require both energy and time. To maximize fitness, an animal adopts a foraging strategy that provides the most benefit (energy) for the lowest cost, maximizing the net energy gained. OFT helps predict the best strategy that an animal can use to achieve this goal. OFT is an ecological application of the optimality model. This theory assumes that the most economically advantageous foraging pattern will be selected for in a species through natural selection. When using OFT to model foraging behavior, organisms are said to be maximizing a variable known as the currency, such as the most food per unit time. In addition, the constraints of the environment are other variables that must be considered. Constraints are defined as factors that can limit the forager's abili ...

Information Grazing
Information grazing refers to the ability to quickly obtain knowledge and facts just in time to solve new problems or answer questions. "Information grazing" can also be "information jumping", jumping from site to site and cherry-picking information seems to "rewire" the brain to deleterious effects or focus on something long enough to fully understand all its implications. Unlike traditional learning, where learning a subject in depth was necessary to draw enough pertinent knowledge to solve new problems or answer questions, information grazing assumes some subjects are so large, fast-changing, interdependent, or esoteric, that traditional methods of learning may be unable to solve new problems or answer questions as efficiently. Information grazing is also one of the most commonly used coping techniques for stress and experts have noticed a trend with people many under the age of 35. The change from a traditional in-depth learning and memorizing of facts to a mentality of quick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Information Foraging
Information foraging is a theory that applies the ideas from optimal foraging theory to understand how human users search for information. The theory is based on the assumption that, when searching for information, humans use "built-in" foraging mechanisms that evolved to help our animal ancestors find food. Importantly, a better understanding of human search behavior can improve the usability of websites or any other user interface. History of the theory In the 1970s optimal foraging theory was developed by anthropologists and ecologists to explain how animals hunt for food. It suggested that the eating habits of animals revolve around maximizing energy intake over a given amount of time. For every predator, certain prey is worth pursuing, while others would result in a net loss of energy. In the early 1990s, Peter Pirolli and Stuart Card from PARC noticed the similarities between users' information searching patterns and animal food foraging strategies. Working together with p ...

Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming. Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site, but studies show that the greatest benefit to biodiversity comes from removing grazing animals from the landscape. ...

Relevance
Relevance is the concept of one topic being connected to another topic in a way that makes it useful to consider the second topic when considering the first. The concept of relevance is studied in many different fields, including cognitive sciences, logic, and library and information science. Most fundamentally, however, it is studied in epistemology (the theory of knowledge). Different theories of knowledge have different implications for what is considered relevant and these fundamental views have implications for all other fields as well. Definition "Something (A) is relevant to a task (T) if it increases the likelihood of accomplishing the goal (G), which is implied by T." (Hjørland & Sejer Christensen, 2002). A thing might be relevant, a document or a piece of information may be relevant. The basic understanding of relevance does not depend on whether we speak of "things" or "information". For example, the Gandhian principles are of great relevance in today's world. Ep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
File Browser
A file manager or file browser is a computer program that provides a user interface to manage files and folders. The most common operations performed on files or groups of files include creating, opening (e.g. viewing, playing, editing or printing), renaming, copying, moving, deleting and searching for files, as well as modifying file attributes, properties and file permissions. Folders and files may be displayed in a hierarchical tree based on their directory structure. Features File transfer Graphical file managers may support copying and moving of files through "copy and paste" and "cut and paste" respectively, as well as through drag and drop, and a separate menu for selecting the target path. While transferring files, a file manager may show the source and destination directories, transfer progress in percentage and/or size, progress bar, name of the file currently being transferred, remaining and/or total number of files, numerical transfer rate, and graphical ...

Gary Marchionini
Gary Marchionini is an American information scientist and educator at the University of North Carolina at Chapel Hill (1998-present). Work Gary Marchionini is a leader in defining theory of human information interaction and exploratory search and his work sits at the intersection of human-computer interaction and information retrieval, a subdomain known as human-computer information interaction ( HCIR). His 1995 book, ''Information Seeking in Electronic Environments'' has been influential in shaping our understanding of search as a learning activity that is dependent not only on individual search capabilities and preferences but on the nature of the topical domain, the search task, and the features of the search system. A pioneer in the development of digital libraries, he led the development of one of the early digital video repositories, the Open Video Project and chaired the 2008 ACM/IEEE Joint Conference on Digital Libraries Conference and was program chair for the 2006 con ...
