Generic Strategy For Classifying A Text Document .1 Generic Strategy for Classifying a Text Document The main steps involved are i) document pre– processing, ii) feature extraction / selection iii) model selection iv) Training and testing the classifier. Information pre–preparing lessens the measure of the information content records essentially. It includes exercises like sentence limit determination [2], characteristic dialect particular stop–word disposal [1] [2] [3] and stemming [2] [4]. Stop–words are practical words which happen as often as possible in the dialect of the content (for instance, „a‟, ‟the‟, ‟an‟, ‟of‟ and so forth in English dialect), so they are not helpful for order. Stemming is the activity of decreasing words to their root or base structure. For English dialect, the Porter‟s stemmer is a prominent calculation [4] [12], which is an addition stripping arrangement of orderly strides for stemming an English word, decreasing the vocabulary of the preparation content by around 33% of its unique size [4]. For instance, utilizing the Porter‟s stemmer, the English word "speculations" would in this manner be stemmed as "speculations → speculation → sum up → general → gener". In situations where the source records are site pages, extra pre–handling is required to evacuate/alter HTML and other script labels [13]. Highlight extraction/choice distinguishes essential words in a content report. This is done utilizing strategies like TF–IDF (term recurrence opposite report recurrence) [14], LSI (dormant Get more content on StudyHub.Vip

The article I chose to critique is "An Efficient Method for Classifying Perfectionists" (Rice, K & Ashby, J, 2007). This article is very informative and detailed in its description of the study of classification of perfectionists. Intro The introduction is lengthy but covers all needed aspects of the study. The stated purpose is clear. It states at the end of the first paragraph that the study is looking for an easy method for counselors or school staff to identify perfectionism within its student body and further identify one's that may need intervention due to maladaptive perfectionism which can lead to increased mental and physical issues. Rice and Ashby (2007) provide an extensive literature review. This review covers most previous ...show more content... They used a variety of other tests along with the APS–R to find these cut off scores and validate their data (dependent variables). These included: Frost's Multidimensional Perfectionism Scale (FMPS), Multidimensional Perfectionism Scale (MPS), the Center for Epidemiological Studies – Depression Scale (CES–D), Satisfaction with Life Scale (SWLS), students grade point average (GPA), and self reported perfectionism rating. I believe the authors provided a strong theoretical perspective and that their literature review backed the need for this type of research and their hypothesis. Method Rice and Ashby use descriptive and correlational research methods for this study. They compiled a sufficient number of subjects and who had completed multiple surveys and tests and correlated the data. This data was quantitative and qualitative in measure. They used tests with ordinal data to obtain raw scores for their correlation. They also provided cross sectional data evaluation by using data from multiple other testing tools. I believe that the research design was adequate for their needs. I do believe that there could be threats to their validity due to the fact that the authors themselves did not collect the data; they used data Get more content on StudyHub.Vip

The System Of Naming And Classifying Organisms The theory of evolution is significant as repeated testing that explains "an observable, verifiable truth – that life on this plant has changed over time." (Fuentes, 22) It is the well–supported history of where all life came from on this planet. Starting over 500 years ago with Nicolaus Copernicus, Galileo Galilei, Francis Bacon, and Isaac Newton paving the way for the possibility of new scientific exploration into studies such as "stratigraphy, the study of the rock and soil layers of the earth" by Robert Hooke and Carolus Linnaeus' study of taxonomy, "the system of naming and classifying organisms" based on morphological similarities and differences, humanity would begin to uncrack the code of where life came from in a nonbiblical sense. (Fuentes, 26) Further studies by George–Louis Leclerc – Comte du Buffon, Erasmus Darwin (Charles' grandfather), Georges Cuvier, James Hutton and Charles Lyell as well as Jean Baptiste Pierre Antoine de Monet – Chevalier de Lamarck's studies in which he "correctly identified the environment as a challenge to organisms and adaptation as the result of changing to meet environmental challenges" helped prompt the formulation of the current understanding of evolution by Charles Darwin and Alfred Russel Wallace each in their own special way. Through the work of curious minds before them, Darwin's inspiration working as a naturalist on the HMS Beagle and traveling to the Galapagos Islands, and Wallace's promptings for publication in 1856, Get more content on StudyHub.Vip

Classifying Business Organizations Essay Classifying Business Organizations Business organizations can be classified in a variety of ways depending on its size, sector, legal status etc. These classifications differ from one firm from another. Legal status has an important bearing on the environment in which the business operates. It is important to have a comprehensive knowledge of the advantages and disadvantages of the several legal forms so that managers and directors can decide which legal form their firm should adopt. The sole trader is the simplest business to develop and has very little legal formalities, obligations or constraints. A sole trader or sole proprietor ...show more content... First, a partnership allows two or more people to work together and bring different skills and resources to the business. Second, if the partnership suffers a loss but the partners have other employment income, the loss can be used to reduce their taxable income, thereby lowering the income tax payable by the partner. There are also two main disadvantages to forming a partnership. Firstly, because a partnership is based on the individual partners, and it is not a separate legal entity, if one of the partners dies, the partnership ends. Secondly, although the resolution of disagreements amongst partners is generally covered under a partnership agreement or case law, it usually is very difficult. There is no Act that exists which sets out rules for settling partnership disputes. Limited companies branch into private limited companies and public limited companies (PLC). A private limited company is one that restricts the right to transfer its shares and limits the number of its members. A public limited company is basically the same as private limited company the chief difference is that shares of Plcs may be offered to the public for subscription. The company may apply to the Stock Exchange for permission for its shares to be listed, thus, providing an effective market for such shares. One of the major advantages of a limited company is that the shareholders are not Get more content on StudyHub.Vip

Classifying Rocks Essay Classifying Rocks Rocks are classified to make it easier on people to identify them in the future. This can be done by a numerous amount of ways. Each rock type has their own specific ways, but there are two distinct characteristics that apply to all. These are texture and composition. These two, along with many others helps to classify igneous, sedimentary, and metamorphic rocks. Igneous rocks are classified first by texture. This is broken down mainly into grain size. First there are intrusive, or plutonic igneous rocks. These types of rocks cool within the crust and forms large, visible crystals . The opposite would be extrusive, or volcanic rocks. These cool at the surface rapidly, forming small grains. A combination ...show more content... Depending on what the sedimentary rock is formed by, determines whether is known as clastic or chemical. Clastic rocks are composed of particles from weathering. They are then sorted by grain size, gravel being the largest and clay being the smallest. A few examples would be sandstones and shales. Chemical sedimentary rocks are biochemical, and contain ions in the solution from weathering. These are also further classified. First you have limestone, which can be either organic or inorganic. An example would be fossiliferous or chalk. Next is dolostone, and it is formed from dolomite. Chert is next; and can be organic or inorganic also. Flint and jasper are some examples of chert. Rock salt and gypsum are what are known as evaporites. These form from the evaporation of saline waters in an arid environment. Finally there is coal, which is organic and forms from buried plant remains and carbon. There is one more type of rock that is classified the same way as the previous two. Metamorphic rocks are pre–existing rocks that are changed by heat and pressure. The pre–existing rock is called the parent rock, or protolith. Metamorphism occurs in these rocks when the minerals become instable. There are two types of metamorphism, contact and regional. Contact is high temperature, low pressure. It is basically a massive rock that is baked. Regional is high pressure and low temperature. Strong fabric, or layering, develops from Get more content on StudyHub.Vip

Classifying Personality Disorders A challenge with classifying personality disorders is that personality disorders are not stable over time while the very definition of personality disorders suggests that they should be stable over time. However, according to figure 15.2, half the people with a personality disorder at some point in time had achieved remission when interviewed two years later (455). Another challenge with classifying personality disorders is that personality disorders are highly comorbid. For instance, a person diagnosed with borderline personality disorder can also be diagnosed with paranoid personality disorder–they also predict poorer outcomes for these disorders (another challenge). Moreover, it was found that more than 50% of people diagnosed with a personality disorder also met the diagnostic criteria for another personality disorder. Furthermore, in the alternative DSM–5 diagnoses (appears in the appendix of the DSM 5) are based on personality traits and includes two types of dimensional scores that can be rated using self–report items. The two types of dimensional scores are 5 personality trait domains and 25 more specific personality trait facets. For instance, negative affectivity includes anxiousness, emotional ...show more content... Although, for some personality disorders, little research was conducted regarding treatments. Moreover, treatment of schizotypal personality disorder is similar to treatment of schizophrenia and thus antipsychotic medication can help. Treatment of avoidant personality disorder is also similar to treatment of social anxiety disorder where antidepressants and behavioral treatment can help. Dialectical behavior therapy, psychodynamic therapy and longer term versions of cognitive therapy have been shown some support as treatment for borderline personality disorder . Lastly, psychotherapy is considered the best treatment for personality Get more content on StudyHub.Vip

Challenges in defining and classifying normal & abnormal behavior with regards to age In the study of abnormal psychology, one of the contentions often debated upon is the determination of abnormal behavior in terms of specific demographics, such as age, gender, and race. However, determining abnormal behavior in terms of age (for example) is a problematic endeavor in that the concept of 'abnormal behavior' itself is subject to different social (cultural) interpretations. One of the challenges encountered in determining normal and abnormal behavior in general (which includes age) is social norms. Because social norms vary across societies and cultures, an acceptable behavior in one culture might be considered abnormal in another. Another challenge to determining normal/abnormal behavior is "historical variation" in terms of acceptable and unacceptable behavior. An example would be the hyperactivity of children: before, this behavior is considered normal as children are considered playful and have short attention span as a result. However, over time, psychologists have identified this kind of behavior as not normal for children, and individuals who demonstrate hyperactivity and very short attention span as having attention–deficit hyperactivity disorder (ADHD) (Butcher, 2010:146). At best, objective determination of normal/abnormal behavior is through diagnostic systems, one of which is the Diagnostic and Statistical Manual of Mental Disorders, also called DSM.

Classification of Organisms Essay Taxonomy is the study of the classification of organisms, it is the organization (separation) of all the known organisms into groups based on their shared features, these groups are then organized into further, larger groups. These groups are all referred to as Taxa (Taxon – singular). The taxa used in taxonomy are: Species , Genus, Family, Order, Class, Phylum and kingdom, each group getting larger going form species to kingdom.

The first name is always a noun and the second an adjective. The relation between Phylogeny and Classification Phylogeny is the evolutionary history of a species, it is a valuable biological mechanism used to determine what genus a species may fall into, as species which have very similar (homologous) features can be assumed to have evolved from the same common ancestors, e.g. horses donkeys and zebras all have homologous features and can all be filed under the genus Equus. Artificial selection Humans have also had a hand in how many of the animals we see every day are the way they are. Take Dogs for example, they have been bred to produce a wide variety of qualities that we find desirable in them, and these can be behavioural, or physical properties. Guard dogs have been bred to have phenotypes such as broad shoulders, heavy build and they also have been selectively bred to be aggressive and territorial other dogs, such as terriers have been bred to be small and fairly docile, ideal qualities for a house pet. In this case Humans have taken the place of natural selection for the dogs, to tailor them to our requirements. Desirable phenotypes which are recognized in the

Classifying Countries Of The Modern World Classifying Countries of the Modern World The ocean is a vast pool with many different kinds of fish, no fish is exactly the same. You can say the same about the countries of the world, but the best way to put all these countries into groups is by judging whether they are developed or developing. Countries develop at their own pace and geographers use the stage of their development to categorize them. For example, take Japan and Ghana. Both countries are very different in almost every aspect of life, Japan is a developed country , and Ghana is a developing country . Ghana differs from Japan in population and its growth, as Ghana has a younger population and more difficulties in maintaining the health of their population. Ghana also differs from Japan in its land use and agriculture by having more subsistence farming, while Japan concentrates more on commercial farming. Developed countries, such as Japan, have older and more stable populations than developing countries. One of the statistics that helps define the growth of a population is the total fertility rate(TFR) which is the number of children born per woman. Japan has a very low TFR of 1.4 births per woman which shows that Japan's population is decreasing and will continue to decline because their TFR is well below replacement level. The replacement level fertility rate is 2.1 births per woman and would keep a population completely stable because it accounts for a man, a woman and a small percentage of people who don't Get more content on StudyHub.Vip

Classifying Criminal Cases There are two different ways to classify crimes in a court of law. One being criminal and the other civil. In this paper I will explain the difference between civil and criminal law and how these cases are handled. Criminal law pertains to a crime or an act against the public rather than one individual. The government will bring legal action against the person for committing a crime . If the person is found guilty, the defendant may have to pay some type of a fine, serve time in jail, or be placed on probation (msbar.org). A civil case is a dispute between two people, or parties, on a certain issue. One party can sue the other, and it is then up to a jury to determine if there is liability. The court may order the guilty party to pay money to the other party or to fulfill an obligation. Civil cases are brought by an individual or corporation wanting to collect money that is owed or money due to damages for a crime. A criminal case is brought on by the local, state or federal government ...show more content... He then drove over 90 mph on a two lane road, and swerved around at least 12 other motorists.

He sued Deputy Harris for violating his Fourth Amendment rights and that it was not reasonable to use deadly force to end the pursuit because he had only committed a traffic violation (Scott v. Harris). The element of mens rea is when Mr. Scott decided to flee from the police in a routine traffic stop.This case would be classified as mala prohibita because Mr. Scott decided to run from the police he did it anyway even though it is prohibited by law to do so. This case also has actus reus which is a guilty act. The guilty act was Mr. Scott speeding and fleeing from the police(crime Get more content on StudyHub.Vip

Briggs, Latisha J. HMR630 Week #1 Paper February 7, 2015 The Importance of Classifying and Distinguishing Between Independent Contractors and Employee's Briggs, Latisha J. National University Abstract Through this paper we will explore the importance of distinguishings classifications between independent contractors and employees. We will examine identifying established relationship between employers and workers while covering assigned roles of employees and independent contractors. We will briefly discuss enacted laws and recommended practices to avoid misclassification penalties and consequences. Lastly, we will explore vital factors that should be considered while classifying workers. The Importance of Distinguishing Classification Between Independent Contractors and Employees Determining the classification between an independent contractor and an employee proves to be rather complex, yet vital, regarding tax issues. Therefore, assigning correct classification is critical to both employer and workers that carry out the labor, especially pertaining to benefits and tax payment obligations. Organizations that classify their workers as employees assume financial responsibility for them. Hartman asserts this by stating that, "the distinction, however, is significant for tax law compliance and categorization, for benefit plans, for cost reduction plans, and for discrimination claims" (Bennett–Alexander, Hartman, 2012). Specifically, the employer's Get more content on StudyHub.Vip

The fact that it is a portable computer designed to use anywhere makes the laptop a favorite of many people. The next classification of computers is called the office computers such as workstations or supercomputers. What is the difference between a workstation and desktop computers? "A desktop computer that has a more powerful processor, additional memory and enhanced capabilities for performing a special group of task, such as 3D Graphics or game development" (What are the Different p. 6). Another computer under this classification is the server or networks. "A computer that has been optimized to provide services to other computers over a network. Servers usually have powerful processors, lots of memory and large hard drives" (What are the Differences p. 7). Networks combine several computers in an office or building space. Also, under the classification of business computer is the supercomputer. This type of computer is more expensive than any of the others with it often costing millions of dollars. "Although some supercomputers are single computer systems, most are comprised of multiple high performance computers working in parallel as a single system" (What are the differences 10). Supercomputers usually are used to predict weather, handle bank accounts, or insurance details. Three classifications of computers are home computers, portable computers, and business computers.

Their sole purpose seems to be simply to drain the life out of everyone, all the time. Whiners are different from the bigheads in that they are always looking for help, yet they appear to share a similar weakness for being at the center of attention . Courtesy isn't typical of whiners; if they need to vent at two o'clock in the morning, they don't see a problem with picking up their phone and calling you, and if a whiner wants to have an hour long cry session on your couch, well, that's fine too. They speak with indigent inflections and beg advice from anyone nearby. Whiners operate with emotion comparable to that of the bighead but with a drab sense of passion and feeble undertones. Seemingly afraid to make any life decisions, they constantly seek family advice. They rarely act on any input given; their gain lies not in improving their situations but in the validation they feel from the encouragement and attention they receive in response to their tales of persecution and unexplained illnesses. Fortunately for the whiners , most families aren't complete without at least one member falling into the following group. Of an almost completely different breed are the levels. They are insightful and open–minded, generally honest and receptive. Levels have a tight grip on the way they should operate their own lives and Get more content on StudyHub.Vip

Classifying Types of Shoppers Shopping is a big deal to most people in this particular century. People are trained to shop a few years after they are born. People shop for so many reasons. Some people shop to release stress and others shop just for fun. Some people even classify shopping as a hobby. Just recently, a new kind of shopping has started dominating gradually. Online shopping is little by little vanquishing all other kinds of shopping and it is all thanks to shoppers. Without these dedicated shoppers, shopping would have been a thing of the past. These shoppers are classified into three sub groups which makes identification easier. There are the cheap shoppers, the spendthrifts, and the indifferent shoppers who simply don't carabout anything. Foremost are the cheap shoppers. This types shoppers are also known as bargainers. They are easily recognized in any store because they are usually armed with a calculator and search through the hardest to get at shelves. They are often seen working in pairs. They call their selves tag team partners. Working I pairs enables cheap shoppers to readily compare prices from items in different sections of the store or two separate stores. These shoppers can be found mainly on the weekend, during a huge sale, or in the clearance sections of stores. They are always shopping for cheap items and they are never concerned about the quality. Bargaining is what they do best. It is their belief that no matter how low the price is, it can always be reduced to fit Get more content on StudyHub.Vip

Introduction Mental health disorders has been very strenuous and complex to understand and diagnose, many diagnosis criteria such as DSM have been used to determine the disorders and medication (Szabo, 2011). I am asserting that "Yes, Psychopathology diagnostic classification systems (such as the DSM or ICD) are of little use to health professionals and patients because behaviours are often misidentified and medicalised". To assert this, this paper is going to explore four main topics that contribute to the little use of psychopathology diagnostic classification system, these include downsides for using DSM diagnostic criteria, Medicalisation and misdiagnose, consequences of medicalisation to the health professionals and community and Psychological trauma in patients. Szabo, (2011) states that Diagnostic and Statistical Manual of Mental Disorders (DSM) has been utilised to diagnose and categorize mental illness in psychiatry . However this diagnosis is focused on definitions of operational rather than the cause (Warelow & Holmes, 2011). This paper will first explore the downside of using DSM criteria to diagnose mental health. Downsides for using DSM diagnostic criteria Using the Diagnostic and Statistical Manual of Mental Disorder as a diagnostic method has been of little use for clients and health professionals as this method gives indications that are similar for nearly all mental health issues (Johnstone, 2008). The fact is that there is no individuals who can claim Get more content on StudyHub.Vip
