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] |

Dan Sperber
Dan Sperber (born 20 June 1942 in Cagnes-sur-Mer) is a French social and cognitive scientist and philosopher. His most influential work has been in the fields of cognitive anthropology, linguistic pragmatics, psychology of reasoning, and philosophy of the social sciences. He has developed: an approach to cultural evolution known as the epidemiology of representations or cultural attraction theory as part of a naturalistic reconceptualization of the social; (with British philosopher and linguist Deirdre Wilson) relevance theory; (with French psychologist Hugo Mercier) the argumentative theory of reasoning. Sperber formerly ''Directeur de Recherche'' at the ''Centre National de la Recherche Scientifique'' is Professor in the Departments of Cognitive Science and of Philosophy at the Central European University in Budapest. Background Sperber is the son of Austrian-French novelist Manès Sperber. He was born in France and raised an atheist but his parents, both non-religious A ...

Precision And Recall
In pattern recognition, information retrieval, object detection and classification (machine learning), precision and recall are performance metrics that apply to data retrieved from a collection, corpus or sample space. Precision (also called positive predictive value) is the fraction of relevant instances among the retrieved instances, while recall (also known as sensitivity) is the fraction of relevant instances that were retrieved. Both precision and recall are therefore based on relevance. Consider a computer program for recognizing dogs (the relevant element) in a digital photograph. Upon processing a picture which contains ten cats and twelve dogs, the program identifies eight dogs. Of the eight elements identified as dogs, only five actually are dogs (true positives), while the other three are cats (false positives). Seven dogs were missed (false negatives), and seven cats were correctly excluded (true negatives). The program's precision is then 5/8 (true positives / se ...

Federal Rules Of Evidence
First adopted in 1975, the Federal Rules of Evidence codify the evidence law that applies in United States federal courts. In addition, many states in the United States have either adopted the Federal Rules of Evidence, with or without local variations, or have revised their own evidence rules or codes to at least partially follow the federal rules. History The law of evidence governs the proof of facts and the inferences flowing from such facts during the trial of civil and criminal lawsuits. Before the twentieth century, evidence law was largely the product of decisional law. During the twentieth century, projects such as the California Evidence Code and the Uniform Rules of Evidence encouraged the codification of those common law evidence rules. In 1965, Chief Justice Earl Warren appointed an advisory committee of fifteen to draft the new rules. The committee was composed of U.S. lawyers and U.S. legal scholars. The Federal Rules of Evidence began as rules proposed pursuan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Description
Description is the pattern of narrative development that aims to make vivid a place, object, character, or group. Description is one of four rhetorical modes (also known as ''modes of discourse''), along with exposition, argumentation, and narration. In practice it would be difficult to write literature that drew on just one of the four basic modes. As a fiction-writing mode Fiction-writing also has modes: action, exposition, description, dialogue, summary, and transition. Author Peter Selgin refers to ''methods'', including action, dialogue, thoughts, summary, scenes, and description. Currently, there is no consensus within the writing community regarding the number and composition of fiction-writing modes and their uses. Description is the fiction-writing mode for transmitting a mental image of the particulars of a story. Together with dialogue, narration, exposition, and summarization, description is one of the most widely recognized of the fiction-writing modes. As state ...

Intensional Logic
Intensional logic is an approach to predicate logic that extends first-order logic, which has quantifiers that range over the individuals of a universe (''extensions''), by additional quantifiers that range over terms that may have such individuals as their value (''intensions''). The distinction between intensional and extensional entities is parallel to the distinction between sense and reference. Overview Logic is the study of proof and deduction as manifested in language (abstracting from any underlying psychological or biological processes). Logic is not a closed, completed science, and presumably, it will never stop developing: the logical analysis can penetrate into varying depths of the language (sentences regarded as atomic, or splitting them to predicates applied to individual terms, or even revealing such fine logical structures like modal, temporal, dynamic, epistemic ones). In order to achieve its special goal, logic was forced to develop its own formal tools, mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Economic Development
In the economics study of the public sector, economic and social development is the process by which the economic well-being and quality of life of a nation, region, local community, or an individual are improved according to targeted goals and objectives. The term has been used frequently in the 20th and 21st centuries, but the concept has existed in the West for far longer. " Modernization", "Westernization", and especially "industrialization" are other terms often used while discussing economic development. Historically, economic development policies focused on industrialization and infrastructure; since the 1960s, it has increasingly focused on poverty reduction. Whereas economic development is a policy intervention aiming to improve the well-being of people, economic growth is a phenomenon of market productivity and increases in GDP; economist Amartya Sen describes economic growth as but "one aspect of the process of economic development". Economists primarily focus on the g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poverty
Poverty is the state of having few material possessions or little income. Poverty can have diverse social, economic, and political causes and effects. When evaluating poverty in statistics or economics there are two main measures: ''absolute poverty'' compares income against the amount needed to meet basic needs, basic personal needs, such as food, clothing, and Shelter (building), shelter; ''relative poverty'' measures when a person cannot meet a minimum level of living standards, compared to others in the same time and place. The definition of ''relative poverty'' varies from one country to another, or from one society to another. Statistically, , most of the world's population live in poverty: in Purchasing Power Parity, PPP dollars, 85% of people live on less than $30 per day, two-thirds live on less than $10 per day, and 10% live on less than $1.90 per day ...

Social Justice
Social justice is justice in terms of the distribution of wealth, opportunities, and privileges within a society. In Western and Asian cultures, the concept of social justice has often referred to the process of ensuring that individuals fulfill their societal roles and receive their due from society. In the current movements for social justice, the emphasis has been on the breaking of barriers for social mobility, the creation of safety nets, and economic justice. Social justice assigns rights and duties in the institutions of society, which enables people to receive the basic benefits and burdens of cooperation. The relevant institutions often include taxation, social insurance, public health, public school, public services, labor law and regulation of markets, to ensure distribution of wealth, and equal opportunity. Interpretations that relate justice to a reciprocal relationship to society are mediated by differences in cultural traditions, some of which emphasize t ...

Famine
A famine is a widespread scarcity of food, caused by several factors including war, natural disasters, crop failure, Demographic trap, population imbalance, widespread poverty, an Financial crisis, economic catastrophe or government policies. This phenomenon is usually accompanied or followed by regional malnutrition, starvation, epidemic, and increased death, mortality. Every inhabited continent in the world has experienced a period of famine throughout history. In the 19th and 20th century, generally characterized Southeast and South Asia, as well as Eastern and Central Europe, in terms of having suffered most number of deaths from famine. The numbers dying from famine began to fall sharply from the 2000s. Since 2010, Africa has been the most affected continent of famine in the world. Definitions According to the United Nations World Food Programme, famine is declared when malnutrition is widespread, and when people have started dying of starvation through lack of access to suf ...

Medieval Poetry
Poetry took numerous forms in medieval Europe, for example, lyric and epic poetry. The troubadours and the minnesänger are known for their lyric poetry about courtly love. Among the most famous of secular poetry is ''Carmina Burana'', a manuscript collection of 254 poems. Twenty-four poems of ''Carmina Burana'' were later set to music by German composer Carl Orff in 1936. Examples of medieval poetry Old English religious poetry includes the poem ''Christ'' by Cynewulf and the poem ''The Dream of the Rood'', preserved in both manuscript form and on the Ruthwell Cross. We do have some secular poetry; in fact a great deal of medieval literature was written in verse, including the Old English epic '' Beowulf''. Scholars are fairly sure, based on a few fragments and on references in historic texts, that much lost secular poetry was set to music, and was spread by traveling minstrels, or bards, across Europe. Thus, the few poems written eventually became ballads or lays, and never ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
