Available in PDF, EPUB and Kindle. Book excerpt: Sentiment analysis and opinion mining is the field of study that analyzes people's opinions, sentiments, evaluations, attitudes, and emotions from written language. It is one of the most active research areas in natural language processing and is also widely studied in data mining, Web mining, and text mining. In fact, this research has spread outside of computer science to the management sciences and social sciences due to its importance to business and society as a whole. The growing importance of sentiment analysis coincides with the growth of social media such as reviews, forum discussions, blogs, micro-blogs, Twitter, and social networks. For the first time in human history, we now have a huge volume of opinionated data recorded in digital form for analysis. Sentiment analysis systems are being applied in almost every business and social domain because opinions are central to almost all human activities and are key influencers of our behaviors. Our beliefs and perceptions of reality, and the choices we make, are largely conditioned on how others see and evaluate the world. For this reason, when we need to make a decision we often seek out the opinions of others. This is true not only for individuals but also for organizations. This book is a comprehensive introductory and survey text. It covers all important topics and the latest developments in the field with over 400 references. It is suitable for students, researchers and practitioners who are interested in social media analysis in general and sentiment analysis in particular. Lecturers can readily use it in class for courses on natural language processing, social media analysis, text mining, and data mining. Lecture slides are also available online.

Available in PDF, EPUB and Kindle. Book excerpt: Other people's opinions are important piece of information for making informed decisions. Today the Web has become an excellent source of consumer opinions. However, as the volume of opinionated text is growing rapidly, it is getting impossible for users to read all reviews to make a good decision. Reading different and possibly even contradictory opinions written by different reviewers even make them more confused. In the same way, monitoring consumer opinions is getting harder for the manufactures and providers. These needs have inspired a new line of research on mining customer reviews, or opinion mining. Aspect-based opinion mining, is a relatively new sub-problem that attracted a great deal of attention in the last few years. Extracted aspects and estimated ratings clearly provides more detailed information for users to make decisions and for suppliers to monitor their consumers. In this thesis, we address the problem of aspect-based opinion mining and seek novel methods to improve limitations and weaknesses of current techniques. We first propose a method, called Opinion Digger, that takes advantages of syntactic patterns to improve the accuracy of frequency-based technique. We then move on to model-based approaches and propose an LDA-based model, called ILDA, to jointly extract aspects and estimate their ratings. In our next work, we compare ILDA with a series of increasingly sophisticated LDA models representing the essence of the major published methods in the literature. A comprehensive evaluation of these models indicates that while ILDA works best for items with large number of reviews, it performs poorly when the size of the training dataset is small, i.e., for cold start items. The cold start problem is critical as in real-life data sets around 90% of items are cold start. We address this problem in our last work and propose a LDA-based model, called FLDA. It models items and reviewers by a set of latent factors and learns them using reviews of an item category. Experimental results on real life data sets show that FLDA achieve significant gain for cold start items compared to the state-of-the-art models.

Download or read book Opinion Mining in Information Retrieval written by Surbhi Bhatia and published by Springer Nature. This book was released on 2020-05-19 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses in detail the latest trends in sentiment analysis,focusing on “how online reviews and feedback reflect the opinions of users and have led to a major shift in the decision-making process at organizations.” Social networking has become essential in today’s society. In the past, people’s decisions to buy certain products (and companies’ efforts to sell them) were largely based on advertisements, surveys, focus groups, consultants, and the opinions of friends and relatives. But now this is no longer limited to one’s circle of friends, family or small surveys;it has spread globally to online social media in the form of blogs, posts, tweets, social networking sites, review sites and so on. Though not always easy, the transition from surveys to social media is certainly lucrative. Business analytical reports have shown that many organizations have improved their sales, marketing and strategy, setting up new policies and making decisions based on opinion mining techniques.
Download or read book Sentiment Analysis in Social Networks written by Federico Alberto Pozzi and published by Morgan Kaufmann. This book was released on 2016-10-06 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of Sentiment Analysis is to define automatic tools able to extract subjective information from texts in natural language, such as opinions and sentiments, in order to create structured and actionable knowledge to be used by either a decision support system or a decision maker. Sentiment analysis has gained even more value with the advent and growth of social networking. Sentiment Analysis in Social Networks begins with an overview of the latest research trends in the field. It then discusses the sociological and psychological processes underling social network interactions. The book explores both semantic and machine learning models and methods that address context-dependent and dynamic text in online social networks, showing how social network streams pose numerous challenges due to their large-scale, short, noisy, context- dependent and dynamic nature. Further, this volume: Takes an interdisciplinary approach from a number of computing domains, including natural language processing, machine learning, big data, and statistical methodologies Provides insights into opinion spamming, reasoning, and social network analysis Shows how to apply sentiment analysis tools for a particular application and domain, and how to get the best results for understanding the consequences Serves as a one-stop reference for the state-of-the-art in social media analytics Takes an interdisciplinary approach from a number of computing domains, including natural language processing, big data, and statistical methodologies Provides insights into opinion spamming, reasoning, and social network mining Shows how to apply opinion mining tools for a particular application and domain, and how to get the best results for understanding the consequences Serves as a one-stop reference for the state-of-the-art in social media analytics

Download or read book Aspect Based Sentiment Analysis Using Artificial Intelligence written by Samik Datta and published by Mohammed Abdul Sattar. This book was released on 2024-01-18 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sentiment analyses are widely utilized to recognize the character of the end users and play an essential task in monitoring the user's review. In sentiment analysis, opinion mining is utilized to understand the opinion presented in written language or text. Reviewing the usage of different household objects generate more complexities in e-commerce applications and among service providers. Here, the object presented as movie text, special symbols, and emoticons and dealing with the unstructured data became highly complicated. In the Aspect Based Sentiment Analysis, two kinds of tasks are executed. The procedure to detect the attributes in the object where the people are commenting is called aspect category. In this phase, the object attributes are termed as aspects and aspect value or sentiment identification is performed as the next task with the aspects. Customer reactions are understood quickly in sentiment analysis, and they face more complications in analyzing human languages. NLP is the field connected with computers for processing human languages such as French, English, German etc. It became more essential to design a new model for professionals who are highly close to humans based on their applications and usage. It is complex to allocate different things to the machine, and the dependencies must be addressed. The processes of human textual data processing are the essential field where machines are trained to observe and process the knowledge of data content. These types of observation need a multi-disciplinary technique, and also, the process of naturally attained text is offered to logic, search, machine learning, knowledge representation, planning and statistical technique. In the present internet era, large volumes of text are presented in the form of power-point presentations, word pages and PDF pages. In this case, the programs are needed to generate some sense with the textual documents, and also, they need different NLP approaches. Finally, the search identifies the best optimization technique for the computer. In some cases, the selection is required for processing the data, and also, the search techniques find the good possible solution to obtain the optimal best solution. Moreover, logic is essential to perform effective interference and reasoning. Next, the textual data are modified as logical forms into a machine for processing. Based on knowledge presentation, the embedded knowledge is collected according to machine knowledge. In NLP, the communication procedure is improved regarding the sentence, meaning, phrases, words and syntactic processing that are more essential for NLP.
Download or read book Handbook of Research on Current Trends in Asian Economics Business and Administration written by Akkaya, Bülent and published by IGI Global. This book was released on 2021-10-08 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social sciences have always been an important tool that enables human beings to examine and understand society. Through social sciences, researchers gain understandings of social phenomena and changes by providing commentaries, producing explanations, and attempting to synthesize a diversity of information sets to formulate theories. Since the concept of change has been the hallmark of the new millennium, researchers have witnessed a transformation in every aspect of the modern world at an ever-increasing speed, particularly in the social facet of human life. Ways of thinking that had previously been upheld and taught may, therefore, no longer be appropriate or effective as tools to understand contemporary phenomena and changes. The Handbook of Research on Current Trends in Asian Economics, Business, and Administration is a critical reference source that examines different aspects of social sciences, management, sociology, and education to better understand today’s society and social life in the Asian context. The book identifies trends, impacts, and implications of disruptive technologies for business and socio-economic development as well as strategic advantage on different levels of business and administration. Covering topics that include e-commerce, green management, information technology, economic growth, and distance learning, this book is essential for economists, academicians, government officials, policymakers, social scientists, managers, leaders, behavioral scientists, academicians, researchers, and students.
Download or read book Sentic Computing written by Erik Cambria and published by Springer Science & Business Media. This book was released on 2012-07-28 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book common sense computing techniques are further developed and applied to bridge the semantic gap between word-level natural language data and the concept-level opinions conveyed by these. In particular, the ensemble application of graph mining and multi-dimensionality reduction techniques is exploited on two common sense knowledge bases to develop a novel intelligent engine for open-domain opinion mining and sentiment analysis. The proposed approach, termed sentic computing, performs a clause-level semantic analysis of text, which allows the inference of both the conceptual and emotional information associated with natural language opinions and, hence, a more efficient passage from (unstructured) textual information to (structured) machine-processable data.

Download or read book Sentiment Analysis of Product Reviews written by Chinmay Milind Suryavanshi and published by . This book was released on 2021 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Digital reviews play a critical role in improving global customer interaction and shaping consumer purchasing habits. E-commerce websites generate thousands of reviews about different products on their website. It is almost impossible to read and understand each review and it would take a considerable amount of man-force to decipher each review and understand customer's opinions. Sentiment Analysis is the process of identifying, extracting, and studying subjective knowledge using Natural Language Processing (NLP). In the context of product reviews, it involves studying consumer behavior to understand their shopping interests or patterns and then using that to understand their sentiment towards a product and manufacturer or a company. In the proposed work, over 20,000 reviews have been classified into positive and negative sentiments using Sentiment Analysis and machine learning. This model can then be used to predict the sentiment of the product review entered by the user. Logistic Regression, a linear implementation of Support Vector Machines called Linear Support Vector Classifier (LSVC) and Decision Tree algorithms have been used for the classification of reviews. The results show that the highest accuracy is achieved by Logistic Regression. The review can be entered by the user in our Graphical User Interface (GUI) which is then processed as input to our model which predicts the sentiment. The review along with its classified sentiment will be displayed to the user. The project also proposes an Aspect-Based sentiment analysis approach to extract the aspects or features of the product along with its associated opinion word, both of which are displayed on the command prompt. This Aspect-Based approach will help the business owner to extract the exact features loved or hated by the customers. The GUI is constructed using the Flask framework which uses Python programming language. This study shows that Logistic Regression has the highest accuracy compared to other algorithms.
Download or read book Fuzzy Techniques for Decision Making 2018 written by José Carlos R. Alcantud and published by MDPI. This book was released on 2020-12-02 with total page 776 pages. Available in PDF, EPUB and Kindle. Book excerpt: Zadeh's fuzzy set theory incorporates the impreciseness of data and evaluations, by imputting the degrees by which each object belongs to a set. Its success fostered theories that codify the subjectivity, uncertainty, imprecision, or roughness of the evaluations. Their rationale is to produce new flexible methodologies in order to model a variety of concrete decision problems more realistically. This Special Issue garners contributions addressing novel tools, techniques and methodologies for decision making (inclusive of both individual and group, single- or multi-criteria decision making) in the context of these theories. It contains 38 research articles that contribute to a variety of setups that combine fuzziness, hesitancy, roughness, covering sets, and linguistic approaches. Their ranges vary from fundamental or technical to applied approaches.
