Improving Effectiveness and Efficiency of Sentiment Analysis

Improving Effectiveness and Efficiency of Sentiment Analysis Modha Jalaj S. Chapter – 1 1. Introduction: Big Data has been created lot of buzz in Information Technology word. Big Data contain large amount of data from various sources like Social Media, News Articles, Blogs, Web, Sensor Data and Medical Records etc. Big Data includes Structured, Semi-Structured and Unstructured data. All these data are very useful to extract the important information for analytics. 1.1 Introduction of Big Data: [26] Big Data is differs for other data in 5 Dimensions such as volume, velocity, variety, and value. [26] Volume: Machine generated data will be large volume of data. Velocity: Social media websites generates large data but not massive. Rate at which data acquired from the social web sites are increasing rapidly. Variety: Different types of data will be generated when a new sensor and new services. Value: Even the unstructured data has some valuable information. So extracting such information from large volume of data is more considerable. Complexity: Connection and correlation of data which describes more about relationship among the data. Big Data include social media, Product reviews, movie reviews, News Article, Blogs etc.. So, to analyze this kind of unstructured data is challenging task. This thing makes Big Data a trending research area in computer Science and sentiment analysis is one of the most important part of this research area. As we have lot of amount of data which is certainly express opinion about the Social issues, events, organization, movies and News which we are considering for sentiment analysis and predict the future trends and effect of certain event on society. We can also modify or make the improve strategy for CRM after analysing the comments or reviews of the customer. This kind analysis is the application of Big Data. 1.2 Introduction of Sentiment Analysis: Big Data is trending research area in computer Science and sentiment analysis is one of the most important part of this research area. Big data is considered as very large amount of data which can be found easily on web, Social media, remote sensing data and medical records etc. in form of structured, semi-structured or unstructured data and we can use these data for sentiment analysis. Sentimental Analysis is all about to get the real voice of people towards specific product, services, organization, movies, news, events, issues and their attributes[1]. Sentiment Analysis includes branches of computer science like Natural Language Processing, Machine Learning, Text Mining and Information Theory and Coding. By using approaches, methods, techniques and models of defined branches, we can categorized our data which is unstructured data may be in form of news articles, blogs, tweets, movie reviews, product reviews etc. into positive, negative or neutral sentiment according to the sentiment is expressed in them. Figure 1.2.1: Sentiment Analysis Sentiment analysis is done on three levels [1] Document Level Sentence Level Entity or Aspect Level. Document Level Sentiment analysis is performed for the whole document and then decide whether the document express positive or negative sentiment. [1] Entity or Aspect Level sentiment analysis performs finer-grained analysis. The goal of entity or aspect level sentiment analysis is to find sentiment on entities and/or aspect of those entities. For example consider a statement â€Å"My HTC Wildfire S phone has good picture quality but it has low phone memory storage.† so sentiment on HTCà ¢Ã¢â€š ¬Ã… ¸s camera and display quality is positive but the sentiment on its phone memory storage is negative. We can generate summery of opinions about entities. Comparative statements are also part of the entity or aspect level sentiment analysis but deal with techniques of comparative sentiment analysis. Sentence level sentiment analysis is related to find sentiment form sentences whether each sentence expressed a positive, negative or neutral sentiment. Sentence level sentiment analysis is closely related to subjectivity classification. Many of the statements about entities are factual in nature and yet they still carry sentiment. Current sentiment analysis approaches express the sentiment of subjective statements and neglect such objective statements that carry sentiment [1]. For Example, â€Å"I bought a Motorola phone two weeks ago. Everything was good initially. The voice was clear and the battery life was long, although it is a bit bulky. Then, it stopped working yesterday. [1]† The first sentence expresses no opinion as it simply states a fact. All other sentences express either explicit or implicit sentiments. The last sentence â€Å"Then, it stopped working yesterday† is objective sentences but current techniques can’t express sentiment for the above specified sentence even though it carry negative sentiment or undesirable sentiment. So I try to solve out the above problematic situation using our approach. [1] The Proposed classification approach handles the subjective as well as objective sentences and generate sentiment form them. 1.3 Objectives: The objective of this research work is to improve the effectiveness and efficiency of classification as well as sentiment analysis because this analysis plays a very important role in analytics application. Till now Sentiment analysis focus on Subjectivity or Subjective sentiment i.e. explicit opinion and get idea about the people sentiment view on particular event, issue and products. Sentiment analysis does not consider objective statements although objective statements carry sentiment i.e. implicit opinion. So here the main objective is to handle subjective sentences as well as objective sentences and give better result of sentiment analysis. Classification of unstructured data and analysis of classified unstructured data are major objectives of me. Practical implementation will be also done by me in the next phase. 1.4 Scope: Scope of this dissertation is described as below. We are considering implicit and explicit opinion so sentiment analysis expected to be improved Analysis of unstructured data gives us important information about people choice and view We are proposed an approach which can be applied for close domain like â€Å"Indian Political news article†, â€Å"Movie Reviews†, â€Å"Stock Market News† and Product Review† so, with the consideration of implicit and explicit opinions we can generate precise view of people so industries can define their strategies. Business and Social Intelligence applications use this sentiment analysis so with this approach it’ll be efficient. Applications: There are so many application of Sentiment Analysis which is used now-a-day to generate predictive analysis for unstructured data. Areas of applications are Social and Business intelligence applications, Product reviews help us to define marketing or production strategies, Movie reviews analysis, News Analysis, Consider political news and comments of people and generate the analysis of election, Predict the effect of specific events or issues on people, Emotional identification of person can be also generated, Find trends in the world Comparative view can also be described for products, movies and events, Improve predictive analysis of return of investment strategies. 1.6 Challenges: There are following challenges which are exists in sentiment analysis are Deal with noisy text in sentiment analysis is difficult. Create SentiWordNet for open domain is challenging task i.e. make a universal SentiWordNet is the Challenging task. When a document discusses several entities, it is crucial to identify the text relevant to each entity. Current accuracy in identifying the relevant text is far from satisfactory.[5] There is a need for better modelling of compositional sentiment. At the sentence level, this means more accurate calculation of the overall sentence sentiment of the sentiment-bearing words, the sentiment shifters, and the sentence structure. [5] There are some approaches that use to identify sarcasm, they are not yet integrated within autonomous sentiment analysis systems.[5]

Blind Children :: essays research papers

Blind children, if given a chance, can play and learn right alongside their sighted peers. An open mind, a positive attitude, and a little creativity are usually all it takes to integrate blind students into regular preschool programs. The blind child can learn the same concepts that are taught the other children. The only difference is the method of learning. The blind child must make more use of the other senses. They also need parents and teachers who will allow lots of hands-on experiences. Blind children can learn the same concepts as other children. They may just need to learn it in a different method such as hands-on. Concepts such as big and little, same and different, prepositions (over, under, in, out, behind), shapes, number concepts, and others are easily taught with concrete objects as an alternative to pictures on paper. Parents of blind children are used to helping their children get accustomed to new places and will guide you in doing so. Usually, one or two visits to the classroom when the other children are not present will be enough to orient the child. Children will use many things to find their way around. The sound of the wall clock or heater may be a way for them to locate themselves. They quickly learn that the story time area is carpeted and that the dress-up area is next to the windows where they can feel the sun or hear the rain. Blindness does not mean that the child is totally without usable vision. Most of blind children have varying amounts of vision, which can be quite helpful. â€Å"Legal blindness† is a term you may hear. It means that a child has 10% or less of normal vision. Teachers need to know that many factors affect what, and how much, a child may see at any particular time. Type of eye condition, fatigue, lighting, excitement, etc. all affect a partially sighted child’s vision. There is little need to worry about the comfort the blind child will have with its peers in the classroom.

Behaviors of two Revenue and Profit Maximization: A Companion of Two Economic Models

Revenue is often simplified in economics or basic finance projections to â€Å"Price x Quantity† (the price of a good times the number of goods sold) though it is rarely this simple in actuality. Net revenue (revenue – returns) is used when sales returns are a factor in the business (http://en. wikipedia. org)†. â€Å"Our first look at firm behavior comes within the context of perfect competition. What comes below is a step-by-step explanation of how perfectly competitive firms maximize their profits, both algebraically and graphically, and a discussion of our result (http://www. louisville. edu)†.Remember that, in perfectly competitive markets, no individual firm has any influence over the market price (since there are many firms and each is a small player in the overall market). Since each firm's product is identical to that of other firms (i. e. products are homogeneous), all firms face the same price. Objectives The paper is a summary of a journal of ec onomic literature. This article is about revenue versus profit maximization. This covers the differences of behavior by the type of control and market power. Also, it illustrates the different behaviors and model firms can use to profit and revenue.Profit maximization was used to critically evaluate the different article models. Revenues versus Profit maximization: Differences in Behavior by the Type of Control and by Market Power Professor Baumol did not favor to the neoclassical theory. He suggested maximizing the total revenues not the profit. This is so called minimum profit constraint or rather spotty observation of business behavior. It is purposely to test empirically the maximization revenues (RM). So it’s expected that large firms falls into specification firms. To which, is in turn into two classifications; Olig holistic firm and owner’s interest firm.The first type of firm is further classified as to the theory of â€Å"Oligopoly†. While the owner int erest firm, the second type means no management interest. While firms cannot individually influence the market price through their actions, they can collectively. Therefore, our starting point will be the market demand and supply curves. These are the same demand and supply curves from the earlier material on Consumer Theory (i. e. they do all the same tricks, like demand shifting when there's a change in income, which those other demand and supply curves did.
