unreferenced date October 2007 Text normalization is a process by which writing text is transformed in some way to make it consistent in a way which it might not have been before. Text normalization is often performed before text is processed in some way, such as generating speech synthesis synthesized speech , automated language translation , storage in a database , or comparison. Examples of text normalization Unicode normalization converting all letters to lower or upper case removing punctuation removing accent marks and other diacritics from letters expanding abbreviations removing stopwords or too common words stemming While this may be done manually, and usually is in the case of ad hoc and personal documents, many programming language s support mechanisms which enable text normalization. Text normalization is useful, for example, for comparing two sequences of characters which mean the same but are represented differently. The examples of this kind of normalization include, but not limited to, don t vs do not , I m vs I am , Can t vs Cannot . Further, 1 and one are the same, 1st is the same as first , and so on. Instead of treating these strings as different, through text processing, one can treat them as the same. Category Unicode compu sci stub pl Normalizacja tekstu de Normalisierung Text ... more details
Audio normalization or peak normalization is the process of uniformly increasing or decreasing the amplitude of an entire Sound recording and reproduction audio signal so that the resulting peak amplitude matches a desired target the norm . Description Specifically, normalization applies a constant amount of gain to the selected region of the recording to bring the highest peak to a target level, usually to 1.0, or to 6.0 dB, in order to allow for addition of two channels without exceeding 0.0 dBFS, or 100 0 dB Fact date March 2009 . This differs from Audio level compression dynamics compression , which applies varying levels of gain over a recording to fit the level within a minimum and maximum range. Normalization applies the same amount of gain across the selected region of the recording so that the relative dynamics and Signal to noise ratio signal to noise ratio are unchanged. Normalization is often used when remastering audio tapes for CD production Fact date March 2009 , in order to maximize the signal level while not changing the signal to noise ratio. It is often combined with Audio level compression dynamic range compression and limiting hard limiting to increase the apparent volume of a CD. It is typically applied along with other audio and digital processing, such as dithering . Normalization is commonly amongst the functions provided by a digital audio workstation . Normalization is different than loudness leveling systems such as Replay Gain in that it only searches for the highest peak it does not account for the apparent loudness of the content. As such, normalization is generally used in order to prevent Clipping audio clipping in the mastering stage of a recording.

sociology Normalization refers to social processes through which ideas and actions come to be seen as normality behavior normal and become taken for granted or natural in everyday life. In sociological theory normalization appears in two forms. First, the concept of normalization is found in the work of Michel Foucault , especially Discipline and Punish , in the context of his account of disciplinary power. As Foucault used the term, normalization involved the construction of an idealized norm of conduct &ndash for example, the way a proper soldier ideally should stand, march, present arms, and so on, as defined in minute detail &ndash and then rewarding or punishing individuals for conforming to or deviating from this ideal. ref Foucault, Michel, 1990.

The Trouble with Normal Postwar Youth and the Making of Heterosexuality . In Michelle Webber and Kate Bezanson, eds., Rethinking Society in the 21st Century Critical Readings in Sociology . Canadian Scholars Press Inc. ref . In Foucault s account, normalization was one of an ensemble of tactics for exerting the maximum social control with the minimum expenditure of force, which Foucault calls disciplinary power . Disciplinary power emerged over the course of the 19th century, came to be used extensively in military barracks, hospitals, asylums, schools, factories, offices, and so on, and hence became a crucial aspect of social structure in modern societies.

A normalization is sometimes based on a property. Quantile normalization , for instance, is normalization based on the magnitude quantile of the measures. In another usage in statistics, normalization refers to the division of multiple sets of data by a common variable in order to negate that variable s effect on the data, thus allowing underlying characteristics of the data sets to be compared this allows data on different scales to be compared, by bringing them to a common scale. In terms of levels of measurement , these ratios only make sense for ratio measurements where ratios of measurements are meaningful , not interval measurements where only distances are meaningful, but not ratios . Parametric normalization frequently uses pivotal quantity pivotal quantities functions whose sampling distribution does not depend on the parameters and particularly ancillary statistic s pivotal quantities that can be computed from observations, without knowing parameters. Examples There are various normalizations in statistics nondimensional ratios of errors, residuals, means and standard deviations, which are hence scale invariant some of which may be summarized as follows.

Unreferenced stub auto yes date December 2009 Context date October 2009 In neuroimaging , spatial normalization is an image processing step, more specifically an image registration method. Human brains differ in size and shape, and one goal of spatial normalization is to deform human brain scans so one location in one subject s brain scan corresponds to the same location in another subject s brain scan. It is often performed in research based functional neuroimaging where one wants to find common brain activation across multiple human subjects. The brain scan can be obtained from magnetic resonance imaging MRI or positron emission tomography PET scanners. There are two steps in the spatial normalization process Specification estimation of warp field Application of warp field with resampling The estimation of the warp field can be performed in one modality, e.g., MRI, and be applied in another modality, e.g., PET, if MRI and PET scans exist for the same subject and they are Image registration coregistered . Spatial normalization typically employs a 3 dimensional nonrigid transformation model a warp field for warping image processing warping a brain scan to a template. The warp field might be parametrized by basis function s such as cosine and polynomial polynomia . There is a number of programs that implement both estimation and application of a warp field. It is a part of the Statistical parametric mapping SPM and AIR program AIR programs.

In statistics, quantile normalization is a technique for making two probability distribution distributions identical in statistical properties. To quantile normalize a test distribution to a reference distribution of the same length, sort the test distribution and sort the reference distribution. The highest entry in the test distribution then takes the value of the highest entry in the reference distribution, the next highest entry the next highest entry in the reference distribution, and so on, until the test distribution is a perturbation of the reference distribution. To quantile normalize two or more distributions to each other, without a reference distribution, sort as before, then set to the average usually, arithmetical mean of the distributions. So the highest value in all cases becomes the mean of the highest values, the second highest value becomes the mean of the second highest values, and so on. Generally a reference distribution will be one of the standard statistical distributions such as the Gaussian distribution or the Poisson distribution . The reference distribution can be generated randomly or from taking regular samples from the cumulative distribution function of the distribution. However any reference distribution can be used. Quantile normalization is frequently used in microarray data analysis.

URL normalization or URL canonicalization is the process by which Uniform Resource Locator URLs are modified and standardized in a consistent manner. The goal of the normalization process is to transform a URL into a normalized or canonical URL so it is possible to determine if two syntactically different URLs may be equivalent. Search engine s employ URL normalization in order to assign importance to web pages and to reduce indexing of duplicate pages. Web crawler s perform URL normalization in order to avoid crawling the same resource more than once. Web browsers may perform normalization to determine if a link has been visited or to determine if a page has been cached. Normalization process There are several types of normalization that may be performed. Some of them are semantics preserving and some are not. Semantic preserving normalizations The following normalizations are described in RFC 3986 ref http tools.ietf.org html rfc3986 section 6 RFC 3986, Section 6 Normalization and Comparison ref to result in equivalent URLs Converting the scheme and host to lower case.

In image processing , normalization is a process that changes the range of pixel intensity values. Applications include photographs with poor contrast vision contrast due to glare, for example. Normalization is sometimes called contrast stretching. In more general fields of data processing, such as digital signal processing , it is referred to as dynamic range expansion. The purpose of dynamic range expansion in the various applications is usually to bring the image, or other type of signal, into a range that is more familiar or normal to the senses, hence the term normalization. Often, the motivation is to achieve consistency in dynamic range for a set of data, signals, or images to avoid mental distraction or fatigue. For example, a newspaper will strive to make all of the images in an issue share a similar range of grayscale . Normalization is a linear process. If the intensity range of the image is 50 to 180 and the desired range is 0 to 255 the process entails subtracting 50 from each of pixel intensity, making the range 0 to 130. Then each pixel intensity is multiplied by 255 130, making the range 0 to 255. Auto normalization in image processing software typically normalizes to the full dynamic range of the number system specified in the image file format. The normalization process will produce iris regions, which have the same constant dimensions, so that two photographs of the same iris under different conditions will have characteristic features at the same spatial location.

In mathematics , the Noether normalization lemma is a result of commutative algebra , introduced in harv Noether 1926 . A simple version states that for any Field 28mathematics 29 field k , and any finitely generated commutative k algebra A , there exists a nonnegative integer d and algebraically independent elements y sub 1 sub , y sub 2 sub , ..., y sub d sub in A such that A is a finitely generated module over, and hence also an integral extension of, the polynomial ring B k y sub 1 sub , y sub 2 sub , ..., y sub d sub . The integer d is uniquely determined by A it is the Krull dimension of A . When A is an integral domain , d is then the transcendence degree of the field of fractions of A over k . The lemma can be understood geometrically. Suppose A is integral. Let B be the coordinate ring of d dimensional affine space math mathbb A d k math , and A as the coordinate ring of some other d dimensional affine variety X . Then the inclusion map B &rarr A induces a surjective finite morphism of affine varieties math X to mathbb A d k math . The conclusion is that any affine variety is a branched covering of affine space. When k is infinite, such a branched covering map can be constructed by taking a general projection from an affine space containing X to a d dimensional subspace. The form of the Noether normalization lemma stated above can be used as an important step in proving Hilbert s Nullstellensatz . This gives it further geometric importance, at least formally, as the Nullstellensatz underlies the development of much of classical algebraic geometry .

A database refactoring is a simple change to a database schema that improves its design while retaining both its behavioral and informational semantics. A database refactoring is conceptually more difficult than a code refactoring code refactorings only need to maintain behavioral semantics while database refactorings also must maintain informational semantics. ref Scott Ambler and Pramod Sadalage 2006 . Refactoring databases Evolutionary database design . Addison Wesley. ISBN 978 0321293534 ref The process of database refactoring is the act of applying database refactorings to evolve an existing database schema database refactoring is a core practice of evolutionary database design . You refactor a database schema for one of two reasons to develop the schema in an evolutionary manner in parallel with the evolutionary design of the rest of your system or to fix design problems with an existing legacy database schema Database refactoring does not change the way data is interpreted or used and does not fix computer bug bug s or add new functionality.
