An expert is somebody who has a broad and deep understanding and competence in terms of knowledge , skill and experience through practice and education in a particular field or area of study. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials , training , education , profession , publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally ) rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage . The individual was usually a profound thinker distinguished for wisdom and sound judgment .
89-396: Cyclopedia , cyclopaedia and cyclopedien are archaic terms for an encyclopedia . The term may specifically refer to: Encyclopedia An encyclopedia ( American English ) or encyclopaedia ( British English ) (from Greek ἐγκύκλιος παιδεία meaning 'general education') is a reference work or compendium providing summaries of knowledge , either general or special, in

"Expert" is also being mistakenly interchanged with the term " authority " in new media. An expert can be an authority if through relationships to people and technology, that expert
267-428: A CD-ROM disc. The user would execute the encyclopedia's software program to see a menu that allowed them to start browsing the encyclopedia's articles, and most encyclopedias also supported a way to search the contents of the encyclopedia. The article text was usually hyperlinked and also included photographs , audio clips (for example in articles about historical speeches or musical instruments), and video clips . In
356-605: A Systematic Dictionary of the Sciences, Arts and Crafts'), better known as Encyclopédie ( French: [ɑ̃siklɔpedi] ), was a general encyclopedia published in France between 1751 and 1772, with later supplements, revised editions, and translations. It had many writers, known as the Encyclopédistes . It was edited by Denis Diderot and, until 1759, co-edited by Jean le Rond d'Alembert . The Encyclopédie
445-734: A compendium of articles (either wholly or partially taken) from a specific encyclopedia. Four major elements define an encyclopedia: its subject matter, its scope, its method of organization, and its method of production: Some works entitled "dictionaries" are similar to encyclopedias, especially those concerned with a particular field (such as the Dictionary of the Middle Ages , the Dictionary of American Naval Fighting Ships , and Black's Law Dictionary ). The Macquarie Dictionary , Australia's national dictionary, became an encyclopedic dictionary after its first edition in recognition of
534-456: A critique of the expert systems literature, Dreyfus & Dreyfus suggest: If one asks an expert for the rules he or she is using, one will, in effect, force the expert to regress to the level of a beginner and state the rules learned in school. Thus, instead of using rules he or she no longer remembers, as the knowledge engineers suppose, the expert is forced to remember rules he or she no longer uses. ... No amount of rules and facts can capture
623-446: A discussion by fiat. In other words, the community, rather than single individuals, direct the course of discussion. The production of knowledge, then, as a process of dialogue and argumentation, becomes an inherently rhetorical activity. Hartelius calls attention to two competing norm systems of expertise: “network norms of dialogic collaboration” and “deferential norms of socially sanctioned professionalism”; Misplaced Pages being evidence of
712-440: A disease correctly; etc. The word expertise is used to refer also to expert determination , where an expert is invited to decide a disputed issue. The decision may be binding or advisory, according to the agreement between the parties in dispute. There are two academic approaches to the understanding and study of expertise. The first understands expertise as an emergent property of communities of practice . In this view expertise
801-467: A function of its knowledge production. Going over the historical development of the encyclopedic project, Hartelius argues that changes in traditional encyclopedias have led to changes in traditional expertise. Misplaced Pages's use of hyperlinks to connect one topic to another depends on, and develops, electronic interactivity meaning that Misplaced Pages's way of knowing is dialogic. Dialogic expertise then, emerges from multiple interactions between utterances within

Expert In specific fields, the definition of expert is well established by consensus and therefore it is not always necessary for individuals to have a professional or academic qualification for them to be accepted as an expert. In this respect,

Hartelius acknowledges that knowledge , experience , training , skill , and qualification are important dimensions of expertise but posits that the concept is more complex than sociologists and psychologists suggest. Arguing that expertise is rhetorical, then, Hartelius explains that expertise "is not simply about one person's skills being different from another's. It
1157-412: A middle grade of understanding is generally known as a technician and often employed to assist experts. A person may well be an expert in one field and a layperson in many other fields. The concepts of experts and expertise are debated within the field of epistemology under the general heading of expert knowledge. In contrast, the opposite of a specialist would be a generalist or polymath . The term

Based on simulations, they estimated that about 50,000 chunks (units of memory) are necessary to become an expert, and hence the many years needed to reach this level. More recently, the CHREST model (Chunk Hierarchy and REtrieval STructures) has simulated in detail a number of phenomena in chess expertise (eye movements, performance in
1335-404: A particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries . Generally speaking, encyclopedia articles focus on factual information concerning the subject named in
1424-581: A problem, or clarify uncertainties where normally one or more human experts would need to be consulted) typically is grounded on the premise that expertise is based on acquired repertoires of rules and frameworks for decision making which can be elicited as the basis for computer supported judgment and decision-making. However, there is increasing evidence that expertise does not work in this fashion. Rather, experts recognize situations based on experience of many prior situations. They are in consequence able to make rapid decisions in complex and dynamic situations. In
1513-405: A prominent place in libraries , schools and other educational institutions. The appearance of digital and open-source versions in the 21st century, such as Misplaced Pages (combining with the wiki website format), has vastly expanded the accessibility, authorship, readership, and variety of encyclopedia entries. Indeed, the purpose of an encyclopedia is to collect knowledge disseminated around

With the information traditionally associated with individual experts now stored within a text produced by a collective, knowing about something is less important than knowing how to find something. As he puts it, "With the internet, the historical power of subject matter expertise is eroded: the archival nature of the Web means that what and how to information
1691-447: A shepherd with fifty years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep. Research in this area attempts to understand the relation between expert knowledge, skills and personal characteristics and exceptional performance. Some researchers have investigated the cognitive structures and processes of experts. The fundamental aim of this research
1780-614: A similar token, a fear of experts can arise from fear of an intellectual elite's power. In earlier periods of history, simply being able to read made one part of an intellectual elite. The introduction of the printing press in Europe during the fifteenth century and the diffusion of printed matter contributed to higher literacy rates and wider access to the once-rarefied knowledge of academia. The subsequent spread of education and learning changed society, and initiated an era of widespread education whose elite would now instead be those who produced
1869-540: A specific field, an expert has: Marie-Line Germain developed a psychometric measure of perception of employee expertise called the Generalized Expertise Measure. She defined a behavioral dimension in experts, in addition to the dimensions suggested by Swanson and Holton. Her 16-item scale contains objective expertise items and subjective expertise items.

An important feature of expert performance seems to be the way in which experts are able to rapidly retrieve complex configurations of information from long-term memory. They recognize situations because they have meaning. It is perhaps this central concern with meaning and how it attaches to situations which provides an important link between
2047-590: Is a German-language encyclopedia which until 2009 was published by the F. A. Brockhaus printing house. The first edition originated in the Conversations-Lexikon published by Renatus Gotthelf Löbel and Franke in Leipzig 1796–1808. Renamed Der Große Brockhaus in 1928 and Brockhaus Enzyklopädie from 1966, the current 21st thirty-volume edition contains about 300,000 entries on about 24,000 pages, with about 40,000 maps, graphics and tables. It
2136-416: Is a linguistic work that primarily focuses on an alphabetical listing of words and their definitions . Synonymous words and those related by the subject matter are to be found scattered around the dictionary, giving no obvious place for in-depth treatment. Thus, a dictionary typically provides limited information , analysis or background for the word defined. While it may offer a definition, it may leave

Many sites and search engines such as Google and Technorati use the term "authority" to denote the link value and traffic to a particular topic. However, this authority only measures populist information. It in no way assures that

The earliest encyclopedic work to have survived to modern times is the Naturalis Historia of Pliny the Elder , a Roman statesman living in the 1st century AD, a work indebted to Varro (1st century BCE). He compiled a work of 37 chapters covering natural history , architecture, medicine, geography , geology, and all aspects of
2403-503: Is also fundamentally contingent on a struggle for ownership and legitimacy." Effective communication is an inherent element in expertise in the same style as knowledge is. Rather than leaving each other out, substance and communicative style are complementary. Hartelius further suggests that Misplaced Pages's dialogic construction of expertise illustrates both the instrumental and the constitutive dimensions of rhetoric; instrumentally as it challenges traditional encyclopedias and constitutively as
2492-598: Is most famous for representing the thought of the Enlightenment . According to Denis Diderot in the article "Encyclopédie", the Encyclopédies aim was "to change the way people think" and for people to be able to inform themselves and to know things. He and the other contributors advocated for the secularization of learning away from the Jesuits . Diderot wanted to incorporate all of the world's knowledge into

Among the areas covered were: grammar , rhetoric , mathematics , geometry , music , astronomy , medicine , law , the Catholic Church and heretical sects, pagan philosophers , languages , cities , animals and birds , the physical world , geography , public buildings , roads , metals , rocks , agriculture , ships , clothes , food , and tools . Another Christian encyclopedia
2670-471: Is no better than that of novices. The first principle of skilled memory, the meaningful encoding principle, states that experts exploit prior knowledge to durably encode information needed to perform a familiar task successfully. Experts form more elaborate and accessible memory representations than novices. The elaborate semantic memory network creates meaningful memory codes that create multiple potential cues and avenues for retrieval. The second principle,
2759-434: Is readily available." The rhetorical authority previously afforded to subject matter expertise, then, is given to those with the procedural knowledge of how to find information called for by a situation. An expert differs from the specialist in that a specialist has to be able to solve a problem and an expert has to know its solution .

In the second view, expertise is a characteristic of individuals and is a consequence of the human capacity for extensive adaptation to physical and social environments. Many accounts of the development of expertise emphasize that it comes about through long periods of deliberate practice. In many domains of expertise estimates of 10 years' experience deliberate practice are common. Recent research on expertise emphasizes

3738-410: The retrieval structure principle states that experts develop memory mechanisms called retrieval structures to facilitate the retrieval of information stored in long-term memory. These mechanisms operate in a fashion consistent with the meaningful encoding principle to provide cues that can later be regenerated to retrieve the stored information efficiently without a lengthy search. The third principle,

The modern encyclopedia evolved from the dictionary in the 18th century; this lineage can be seen in the alphabetical order of print encyclopedias.

5162-496: The dynamics behind dialogic expertise creates new information nonetheless. Knowledge production is created as a function of dialogue. According to Hartelius, dialogic expertise has emerged on Misplaced Pages not only because of its interactive structure but also because of the site's hortative discourse which is not found in traditional encyclopedias. By Misplaced Pages's hortative discourse, Hartelius means various encouragements to edit certain topics and instructions on how to do so that appear on

Drawing on a Bakhtinian framework, Hartelius posits that Misplaced Pages is an example of an epistemic network that is driven by the view that individuals' ideas clash with one another so as to generate expertise collaboratively.

6764-516: The rhetorical problems faced by experts: just as someone with autonomous expertise may not possess the skill to persuade people to hold their points of view, someone with merely attributed expertise may be persuasive but lack the actual knowledge pertaining to a given subject. The problem faced by audiences follows from the problem facing experts: when faced with competing claims of expertise, what resources do non-experts have to evaluate claims put before them? Hartelius and other scholars have also noted
6853-435: The rulers, Plato said, must tell the people of the city "the noble lie" to keep them passive and content, without the risk of upheaval and unrest. In contemporary society, doctors and scientists, for example, are considered to be experts in that they hold a body of dominant knowledge that is, on the whole, inaccessible to the layman. However, this inaccessibility and perhaps even mystery that surrounds expertise does not cause
6942-428: The same number of chunks, but the size of the chunks varied with subjects' prior experience. Experts' chunks contained more individual pieces than those of novices. This research did not investigate how experts find, distinguish, and retrieve the right chunks from the vast number they hold without a lengthy search of long-term memory. Skilled memory enables experts to rapidly encode, store, and retrieve information within
7031-608: The scientist and statesman Shen Kuo (1031–1095) with his Dream Pool Essays of 1088; the statesman, inventor, and agronomist Wang Zhen (active 1290–1333) with his Nong Shu of 1313; and Song Yingxing (1587–1666) with his Tiangong Kaiwu . Song Yingxing was termed the " Diderot of China" by British historian Joseph Needham . Before the advent of the printing press, encyclopedic works were all hand-copied and thus rarely available, beyond wealthy patrons or monastic men of learning: they were expensive, and usually written for those extending knowledge rather than those using it. During
7120-426: The site. One further reason to the emergence of dialogic expertise on Misplaced Pages is the site's community pages , which function as a techne ; explicating Misplaced Pages's expert methodology. Building on Hartelius, Damien Pfister developed the concept of "networked expertise". Noting that Misplaced Pages employs a "many to many" rather than a "one to one" model of communication, he notes how expertise likewise shifts to become
7209-535: The things for which those words stand. Thus, while dictionary entries are inextricably fixed to the word described, encyclopedia articles can be given a different entry name. As such, dictionary entries are not fully translatable into other languages, but encyclopedia articles can be. In practice, however, the distinction is not concrete, as there is no clear-cut difference between factual, "encyclopedic" information and linguistic information such as appear in dictionaries. Thus encyclopedias may contain material that
7298-473: The topic, the article can treat the topic's more extensive meaning in more depth and convey the most relevant accumulated knowledge on that subject. An encyclopedia article also often includes many maps and illustrations , as well as bibliography and statistics . An encyclopedia is, theoretically, not written to convince, although one of its goals is indeed to convince its reader of its veracity. In addition, sometimes books or reading lists are compiled from
7387-520: The two separate words were reduced to a single word due to a scribal error by copyists of a Latin manuscript edition of Quintillian in 1470. The copyists took this phrase to be a single Greek word, enkyklopaedia , with the same meaning, and this spurious Greek word became the Neo-Latin word encyclopaedia , which in turn came into English. Because of this compounded word, fifteenth-century readers since have often, and incorrectly, thought that
7476-464: The use of proper nouns in common communication, and the words derived from such proper nouns. There are some broad differences between encyclopedias and dictionaries. Most noticeably, encyclopedia articles are longer, fuller and more thorough than entries in most general-purpose dictionaries. There are differences in content as well. Generally speaking, dictionaries provide linguistic information about words themselves, while encyclopedias focus more on
7565-526: The world around him. This work became very popular in Antiquity , was one of the first classical manuscripts to be printed in 1470, and has remained popular ever since as a source of information on the Roman world, and especially Roman art , Roman technology and Roman engineering . The Spanish scholar Isidore of Seville was the first Christian writer to try to compile a summa of universal knowledge,
7654-837: The world's largest encyclopedia in 2004 at the 300,000 article stage. By late 2005, Misplaced Pages had produced over two million articles in more than 80 languages with content licensed under the copyleft GNU Free Documentation License . As of August 2009, Misplaced Pages had over 3 million articles in English and well over 10 million combined articles in over 250 languages. Today, Misplaced Pages has 6,916,922 articles in English, over 60 million combined articles in over 300 languages, and over 250 million combined pages including project and discussion pages. Since 2002, other 💕s appeared, including Hudong (2005–) and Baidu Baike (2006–) in Chinese, and Google's Knol (2008–2012) in English. Some MediaWiki-based encyclopedias have appeared, usually under
7743-403: The written content itself for consumption, in education and all other spheres. Plato's " Noble Lie ", concerns expertise. Plato did not believe most people were clever enough to look after their own and society's best interest, so the few clever people of the world needed to lead the rest of the flock. Therefore, the idea was born that only the elite should know the truth in its complete form and
7832-422: Was a complete encyclopedia explaining the seven liberal arts . Financial, commercial, legal, and intellectual factors changed the size of encyclopedias. Middle classes had more time to read and encyclopedias helped them to learn more. Publishers wanted to increase their output so some countries like Germany started selling books missing alphabetical sections, to publish faster. Also, publishers could not afford all
7921-586: Was the Institutiones divinarum et saecularium litterarum of Cassiodorus (543–560) dedicated to the Christian divinity and the seven liberal arts. The encyclopedia of Suda , a massive 10th-century Byzantine encyclopedia, had 30,000 entries, many drawings from ancient sources that have since been lost, and often derived from medieval Christian compilers. The text was arranged alphabetically with some slight deviations from common vowel order and placed in
