Natural Language Processing Scope English Language Essay

Natural Language Processing Scope English Language Essay Abstract: The challenging sphere of natural language processing has been a major concern in the field of computer science and artificial intelligence since the late 40s. It encompasses the next strive forward in artificial intelligence to make computers and human interface more flexible and human understandable. Various methods were adopted since its inscription like machine translation, speech recognition, e-teaching, auto tutor etc. Researchers saw it as a likely bridge between human spoken language and computers which used programming languages and binary codes. As mentioned earlier, it is still a challenging task of making a computer to understand human natural language as such. Hence, further enhancements and techniques will foster the demanding yet fruitful and futuristic computational trends. Keywords: NLP Natural Language Processing, Semantic, Syntactic, Lexical, Phonology, MT Machine Translation Introduction: The computational scheme has evolved from basic set of instructions in the form of binary codes to mnemonic instruction codes to programming languages that have prevailed intensively during the later part of twentieth century. Along that evolution came the inspirational research on making the computer understand natural human language and interact with the humans in short applying natural language processing to normal computer usage and beyond. Natural language processing can be defined as a theoretical approach enclosing analysis and manipulation of natural language texts usually spoken by humans. This is done at various levels of linguistic analysis in order to attain a human-like approach to processing of tasks and other problems. It must be noted that NLP is not a single defined standard system but a collection of numerous language processing techniques and methods. Also, in view of facilitating the user and standing true to the name, texts must be of natural language usage and not a set of selected texts that could be used for processing. Because, the later approach would certainly forgo the real meaning of natural language processing. In any NLP system, various levels of linguistic analysis of the text are performed. This is done because humans usually breakup linguistic texts into various levels and then process or understand the language. Human-like approach and processing in the NLP systems are considered as an integral part of AI. The applications of NLP are versatile and are currently being researched and implemented in fields like military science, security systems, virtual reality simulation, medicine and regular computer science and artificial intelligence. The techniques and approaches that have been used or researched so far form the basic platform of NLP. Some of them are based on classification of natural linguistic phonology, morphology, lexical variations, syntactic, semantic, pragmatic levels. Some of the notable works done in this field are: Machine Translation Weaver and Booth (1946) Syntactic Structures Chomsky (1957) Case grammar Fillmore Semantic Networks Quillain Conceptual Dependency Schank Augmented Transition Networks Woods Functional Grammar Kay Also that there have been famous prototypes developed to highlight the impact of particular techniques and principles. They are: ELIZA Weizenbaum SHRDLU Winograd PARRY LUNAR Woods The scope of the article revolves around the evolution of NLP and its implementation in security systems. Methods: Strata of natural language processing: The optimal descriptive way of putting forward the actions that are going on in natural language processing system is through the strata of natural language processing. During the early days of natural language processing, it was held that the different data of natural language processing followed a sequential pattern. But current Psycholinguistic researches have revealed that the system follows rather a synchronic pattern. This is because humans use all of the strata of language processing and they dont follow a sequential pattern. For this reason, in order to achieve high efficiency of NLP system more strata of language processing must be adopted. This stratum deals with the interpretation of speech sounds within and across words. There are three types of rules that are typically used: 1) Phonetic rules for sounds within words 2) Phonemic rules for variations of pronunciation when words are spoken together 3) Prosodic rules for fluctuation in stress and intonation across a sentence. Morphology This strata deal with the componential nature of words, which are composed of morphemes the smallest units of meaning. For example, the word postproduction can be morphologically analyzed into three separate morphemes: the prefix post, the root product and the suffix tion. Since the meaning of each morpheme remains the same across words, humans break down an unknown word into its constituent morphemes in order to understand its meaning. In the same way, an NLP system recognizes the meaning given by each morpheme in order to achieve and interpret meaning. Lexical Both the humans and NLP systems at this stratum, interpret the meaning of individual words. Several types of processing contribute to word-level understanding the first of these being assignment of a single part-of-speech tag to each word. In this processing, words that can function as more than one part-of-speech are assigned the most probable part-of speech tag based on the context in which they occur. Moreover at the lexical stratum, those words that have only one possible sense or meaning can be replaced by a semantic representation of that meaning. The nature of the representation varies according to the semantic theory utilized in the NLP system. One can notice that, a single lexical unit is split into its more basic properties. If there is a set of semantic primitives used across all words, these simplified lexical representations make it possible to unify meaning across words and to produce complex interpretations, much the same as humans do. Syntactic The concept of analysing the sentence by looking into the grammatical composition of a sentence and its dependency is used here. This needs both grammar and a parser. The output achieved here is a representation of the sentence that gives the structural dependency relationships between the words. The efficiency of a parser depends on the different grammars used. Not all NLP applications require a full parse of sentences, therefore the remaining challenges in parsing of prepositional phrase attachment and conjunction scoping no longer stymie those applications for which phrasal and clausal dependencies are sufficient. Syntax conveys meaning in most languages because order and dependency contribute to meaning. For example the two sentences: I smoked a cigarette. and The cigarette smoked me. differ only in terms of syntax, but convey contrasting meanings. Semantic This is the strata at which most people think meaning is determined, however, as we can see in the above defining of the stratum, it is all the levels that contribute to meaning. Semantic processing determines the possible meanings of a sentence by focusing on the interactions among word-level meanings in the sentence. This level of processing can include the semantic disambiguation of words with multiple senses; in an analogous way to how syntactic disambiguation of words that can function as multiple parts-of-speech is accomplished at the syntactic level. Semantic disambiguation permits one and only one sense of polysemous words to be selected and included in the semantic representation of the sentence. For example, amongst other meanings, file as a noun can mean either a folder for storing papers, or a tool to shape ones fingernails, or a line of individuals in a queue. If information from the rest of the sentence were required for the disambiguation, the semantic, not the lexical level, would do the disambiguation. A wide range of methods can be implemented to accomplish the disambiguation, some which require information as to the frequency with which each sense occurs in a particular corpus of interest, or in general usage, some which require consideration of the local context, and others which utilize pragmatic knowledge of the domain of the document. Discourse While syntax and semantics work with sentence-length units, the discourse level of NLP works with units of text longer than a sentence. That is, it does not interpret multisentence texts as just concatenated sentences, each of which can be interpreted singly. Rather, discourse focuses on the properties of the text as a whole that convey meaning by making connections between component sentences. Several types of discourse processing can occur at this level, two of the most common being anaphora resolution and discourse/text structure recognition. Anaphora resolution is the replacing of words such as pronouns, which are semantically vacant, with the appropriate entity to which they refer (30). Discourse/text structure recognition determines the functions of sentences in the text, which, in turn, adds to the meaningful representation of the text. For example, newspaper articles can be deconstructed into discourse components such as: Lead, Main Story, Previous Events, Evaluation, Attributed Quotes, and Expectation. Pragmatic This level is concerned with the purposeful use of language in situations and utilizes context over and above the contents of the text for understanding The goal is to explain how extra meaning is read into texts without actually being encoded in them. This requires much world knowledge, including the understanding of intentions, plans, and goals. Some NLP applications may utilize knowledge bases and inferencing modules. For example, the following two sentences require resolution of the anaphoric term they, but this resolution requires pragmatic or world knowledge. Natural Language processing in textual information retrieval As the reader has probably already deduced, the complexity associated with natural language is especially key when retrieving textual information [Baeza-Yates, 1999] to satisfy a users information needs. This is why in Textual Information Retrieval, NLP techniques are often used [Allan, 2000] both for facilitating descriptions of document content and for presenting the users query, all with the aim of comparing both descriptions and presenting the user the documents that best satisfy their information needs. In other words, a textual information retrieval system carries out the following tasks in response to a users query: Indexing the collection of documents: in this phase, NLP techniques are applied to generate an index containing document descriptions. Normally each document is described through a set of terms that, in theory, best represents its content. When a user formulates a query, the system analyses it, and if necessary, transforms it with the hope of representing the users information needs in the same way as the document content is represented. The system compares the description of each document with that of the query, and presents the user with those documents whose descriptions are closest to the query description. The results are usually listed in order of relevancy, that is, by the level of similarity between the document and query descriptions. C:UsershpDesktopUntitled.bmp The architecture of an information retrieval system As of now there are no NLP techniques that allow us to extract a documents or querys meaning without any mistakes. In fact, the scientific community is divided on the procedure to follow in reaching this goal. In the following section we will explain the functions and peculiarities of the two key approaches to natural language processing: a statistical approach and a linguistic focus. Both proposals differ considerably, even though in practice natural language processing systems use a mixed approach, combining techniques from both focuses. CONCLUSION: Despite the useful universal aspect of programming languages, these languages are still understood only by very few people, unlike the natural languages which are understood by all. The ability to turn natural into programming languages will eventually decrease the gap between very few and all, and open the benefits of computer programming to a larger number of users. In this paper, we showed how current state of-the-art techniques in natural language processing can allow us to devise a system for natural language programming that addresses both the descriptive and procedural programming paradigms. The output of the system consists of automatically generated program skeletons, which were shown to help non-expert programmers in their task of describing algorithms in a programmatic way. As it turns out, advances in natural language processing helped the task of natural language programming. But we believe that natural language processing could also benefit from natural language programming. The process of deriving computer programs starting with a natural language text implies a plethora of sophisticated language processing tools such as syntactic parsers, clause detectors, argument structure identifiers, semantic analyzers, methods for co reference resolution, and so forth which can be effectively put at work and evaluated within the framework of natural language programming. We thus see natural language programming as a potential large scale end-user (or rather, end computer) application of text processing tools, which puts forward challenges for the natural language processing community and could eventually trigger advances in this field.

Eulogy for Daughter :: Eulogies Eulogy

Eulogy for Daughter My Dear Charity, Where do I start?   How do I begin a farewell when I still can't believe you're gone?   How do I say goodbye to a part of my soul? The day you were born I felt this indescribable love.   One I had never known before.   From the beginning of your life I never knew I could have a love that was so strong.   When you were an infant I told people how great you were and they said, "Yeah, but wait until she is two."   When you were two I told people how great you were and they said, "Yeah, but wait until she is ten."   When you were ten I told people how great you were and they said, "Yeah, but just wait until she is 16."   And now you are 16 and I am telling people how great you are. You came into my life and changed me forever.   Over the years people have complimented me for being a good mother but I can't take credit for that.   You were born good and you were the one who was often teaching me.   I believe you are an angel God sent to teach me.   You taught me love.   You taught me honesty.   You taught me how to forgive and how to be strong.   You are the strongest person I have ever known and you gave me strength when I was weak.   When times were sad and tough I looked to you for strength.   You taught me how to be myself.   Most of all you taught me about life and how to live. When you got sick and the doctors told me I should hold you back you taught me it was more important to feel and grow like any other child than to have me hide you under my wing.    It was more important to live.   And that you did.   You danced so beautifully, for years.   And then your greatest joy, cheerleading.   You made me so proud.   You have always been my greatest pride and joy.   I'm not sure how I can live this life without you.   Remember when you would cry and tell me you were so afraid because you didn't want me to die before you.   And I would tell you I wasn't going to die.   And remember me saying you couldn't die before me, so we agreed, we had to go at the same time because neither of us could live without the other.

Innovation in Food and Beverage Outlet

Executive summary â€Å"CONCEPT SELLS AND NOT JUST THE FOOD† – the project is executed only because of the fact that the statement i just made holds true in today’s challenging world. With the progression of the food service industry over the ages, it is appropriate to define a food and beverage outlet as a commercial organisation whose primary objective is profitability by means of discharging food and beverage to a guest. Thus it can be stated that one of the amin motives of the existence of a food and beverage outlet is profitability. Over the years there has been a padigram shift, and it’s not about the food and beverage anymore but it is about the â€Å"whole experience. † Thus, in this project i intend to explore innovations in the food and beverage industry, the various kinds of Entertainment and Novel ideas introduced by restaurateur and see the evolution of the entertainment over the years with the global perspective. The list of activities that i intend to undertake is : Do a detailed research of the innovations that the various renowned outlets across the world have done inorder to attract customers and increase their sales. Visit and study various outlets in mumbai in reference with the innovations done. Study the in-house entertainment provided by the various outlets in mumbai like tendulkar’s, out of the blue, jazz by the bay etc. Take personal interviews of the restaurateurs. Analyse the data acquired. Based on the study, make recommendations for a basic outlet so as to increase its profit. As it is said that â€Å"nowadays people pay for the experience and not just for the food† and also the busy schedule does not allow them to go to different places for enetrtainment and food, combination of entertainment and good food is exactly what is required. Inorder to understand the concept better i am short listing some restaurants in mumbai which have used innovations to drive customers in and will give details of the same. However, does entertainment in a food and beverage outlet actually make a difference to the guest or the outlet? What are the diffrent forms of entertainment that a food and beverage outlet offers? What are the innovations used? These questions will be discussed in depth in the due course of the project.

Inequality within organizations

Inequality within organizations Organizations are institutions which are set up and established based on a certain set of objectives with the aim of ensuring that the vision for which they are set up are obtained or realized. It is worth noting that organizations are institutions which are established and run by human beings.Advertising We will write a custom essay sample on Inequality within organizations specifically for you for only $16.05 $11/page Learn More In this case the success or failure of an organization to reach the stated objectives lay in the hands of the people who are concerned and more importantly in the leader who spells the vision to the members who are within the organization. As an entity, organizations have their own cultures and systems of operation. This implies that there are organizations which operate on principles which ensure that needs of the staff plus the customer or client based are realized and there are other organizations which may not have that aspect at all. Differences are bound to exist amidst people who hold different ideologies and opinions about certain aspects. This is an important aspect in organizations because it gives the organization an opportunity to work and gel in a unique and diverse manner. However, there are cases whereby these differences bring about conflict. These conflicts arise when there is no common ground and consequently cases of inequity crop up among personnel. Inequity may be defined as a situation in which a person perceives that he or she is receiving less than he or she is giving, or is giving less than he or she is receiving. This leads to the experience of tension, and tension motivates a person to act in a manner to resolve the inequity. Eventually the image of the company is harmed as well as the productivity of the employees. It is important as an administrator to work towards ensuring that any form of inequity is resolved. There are several strategies which can be used in resolving inequity and restoring equity to the situation . As an administrator these are some of the strategies that might be put to use. These include altering the person’s outcomes, altering the person’s output, altering the comparison other’s outcomes, altering the comparison other’s inputs, change who is used as a comparison to the other, rationalize the inequity and leave the organizational situation.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More It is important for an administrator to select a strategy or a set of tactics. This is not an easy issue, it is an issue which is very sensitive and which has got long term consequences, thus as the administrator grapples with formulation of a strategy and tactics to restore equity, the range of consequences of alternative actions must be taken into account. This is the only way which will ensure that the effects of the in equity involved are put into consideration and at the same time the parties which feel aggrieved are catered for amicably. Arriving at a conclusion on how to deal with the issues which are faced within an organization is quite important. This is because it enables the person to be in a position of developing strategies that are ethical and establishing a decision making process which caters for the needs of all the persons concerned. In essence ethics in organizations cannot be overlooked because it informs the process of arriving at the desired decision. Ethically, arriving at the right decision entails identifying the root cause of the problem at hand. This is done by developing a step by step approach towards resolving the arising conflict. In this process one has to begin with a consideration of the uncertainties involved in any ethical problem. Secondly the generation of alternative solutions to the problem which at times may entail separating the defining problem and gathering more information towards resolving the conflict and lastly always acting under time pressure to ensure that these conflicts are brought under immediate control.

Political Parties and Pressure Groups Essay Example | Topics and Well Written Essays - 1250 words

Political Parties and Pressure Groups - Essay Example Political Parties and Pressure Groups However, some state officials use this power to fulfill their personal interest. The destructive activities were made possible by the use beyond the power vested upon these government officials. This is the greatest problem of governing. It is apparent that the state is now operating for their own benefits and disregarding the rights of the society. A criminal activity such as corruption which is stealing the money of the society is very visible, where politicians openly ignore their responsibilities as well as their sworn statement towards the public. This practice exhibits gross parasitism, malfeasance and criminality. While these practices were done by those government officials with whom the general public has elected, it has become a question as to why those criminal offences were committed by those "supposed to be" leaders. Are there other factors that greatly influence those practices Do these practices affect democracy Do these practices have any relation to political parties and pressure groups Are political parties and pressure groups a hindrance or an aid in democracy According to Jack L. Davies (2001), political parties can be organized by anyone, can select their own membership and leadership any way they want, and can define any political positions that they want without consulting with anyone else. However, they do not represent any citizens, other than the members of the party itself. They must then present their candidates for election and political positions for approval by referenda as appropriate before their political agenda has any real relevance. Political parties are groups or organizations which aim for certain goals and have their own political ideologies and policies. They seek to attain political power in the government by electing a leader and running in the election in order for these political ideologies and policies to be implemented. Though political parties' aids in democracy by giving the general public a lot of choices of what political party will best serve the nation, political parties have also its own strengths and weaknesses. The bright side of political parties, aside from giving the general public a lot of choices, by free and open competition, is also, as stated by Kenneth Wollack, President of National Democratic Institute, (2005) in new democracies, governments, political parties and civil society are finding ways to work cooperatively to construct and consolidate their nascent democratic institutions. Political parties train political leaders and educate the general public by explaining and defending the government policies. They give the general public some points to ponder by pointing out the weaknesses of the governing party's policies and other party lists' policies at the same time promote their own course of action. These happen during the election campaigns. During election campaigns, these political parties serve as a channel for the general public and the government as well repair damage roads and do other things that the government has recently failed to do that will give benefit to the general public. Political parties have also its own disadvantages. First is, the political leaders who

Communication - Essay Example the film’s running time of 87 is generous, considering the genre. This was a massive box office hit film generating more than $5 million on the first week of release. City Lights was the first Charles Chaplin’s first production after the technology in talking movies was first introduced. Nonetheless, the film did not the technology in its development, wisely so, since the sound equipment used would have trapped the film in sound sets and stages. Since the movie was built on the comedy genre, the actors staying up close to the equipment and this would not have produced the bouts of laughter an expectation, the audience relished. After watching the film, one must contend that the few sound used underscore the silent comedy without any overbearing the audience. In the opening scene, where the mayor unveils a civic statue only to find Charlie Chaplin on its arms enjoying slumber, the speech is shown by sounds sounding like shrills and screeches. Additionally, when Charlie Chaplin swallows the whistle and accidentally causes a concert to stop, followed by a scene in which he makes a call for cab to a stop and then another in which he surrounds himself with dogs. The first and the sequence of scenes as mentioned above, provide, perhaps the only moments when sounds is used. According to Gehring (12), the character, Little Tramp dwelt in the language understood all over the world then, pantomime. A part from these, music is only used in the film, when the synchronized score is used to aid with the movement of the comedy.
