Book Synopsis Application of Latent Dirichlet Allocation in Online Content Generation by : Yajia Yang
Download or read book Application of Latent Dirichlet Allocation in Online Content Generation written by Yajia Yang and published by . This book was released on 2016 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, I apply latent dirichlet allocation(LDA) to cluster 100,000 health related articles using the livestrong.com data set. I first review the previous research progress in topic modeling. Then I introduce how LDA model is constructed. In stead of using simple word counts as model inputs, Part-of-Speech(POS) tagging and Term-Frequency Inverse Document Frequency(tf-idf) transformation are performed in data preprocessing steps in order to improve training efficiency and model interpretability. I further discuss the choices of model parameters, evaluating of model performance and visualization of model outputs from a real world point of view. Finally, I discuss two variations of conventional LDA including paralleled LDA and Online LDA. In addition to a traditional perplexity measure, I discuss how to use cosine similarity and Symmetric Kullback-Leibler Divergence to evaluate clustering performance. Three examples of using LDA outputs as building blocks for more complicated machine learning system are also demonstrated: 1) Cascaded LDA for taxonomy building. 2) In-cluster similarity computing. 3) Auto categorization.

Book Synopsis Artificial Intelligence for Customer Relationship Management by : Boris Galitsky
Download or read book Artificial Intelligence for Customer Relationship Management written by Boris Galitsky and published by Springer Nature. This book was released on 2020-12-23 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second volume of this research monograph describes a number of applications of Artificial Intelligence in the field of Customer Relationship Management with the focus of solving customer problems. We design a system that tries to understand the customer complaint, his mood, and what can be done to resolve an issue with the product or service. To solve a customer problem efficiently, we maintain a dialogue with the customer so that the problem can be clarified and multiple ways to fix it can be sought. We introduce dialogue management based on discourse analysis: a systematic linguistic way to handle the thought process of the author of the content to be delivered. We analyze user sentiments and personal traits to tailor dialogue management to individual customers. We also design a number of dialogue scenarios for CRM with replies following certain patterns and propose virtual and social dialogues for various modalities of communication with a customer. After we learn to detect fake content, deception and hypocrisy, we examine the domain of customer complaints. We simulate mental states, attitudes and emotions of a complainant and try to predict his behavior. Having suggested graph-based formal representations of complaint scenarios, we machine-learn them to identify the best action the customer support organization can chose to retain the complainant as a customer.
Book Synopsis Distributed Diverging Topic Models by : James Andrew Marquardt
Download or read book Distributed Diverging Topic Models written by James Andrew Marquardt and published by . This book was released on 2014 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: In their 2001 work Latent Dirichlet Allocation, Blei, Ng, and Jordan proposed the generative model of the same name that has since become the basis for most research in the field of topic modeling. The model overcame many of the shortcomings of previous probabilistic models such as allowing the inference of topics in documents not present in the learning phase, as well as allowing for topic mixtures. In the past decade the algorithm for inferring the probabilities associated with the model has been implemented in many different languages, been extended to allow topic relationships with other entities such as emotion and document label, and optimized in a variety of ways to allow faster learning. Latent Dirichlet Allocation (LDA) has found applications within a wide variety of disciplines; including digital humanities, computational social science, e-commerce, and government science policy. In short, the numerous advances and applications illustrate the significant influence of the original LDA algorithm. However, in spite of the numerous publications and tools created as a result of LDA, the model suffers from one issue: it is extremely computationally intensive. This shortcoming is so great that its utility towards large datasets of the scale of those mined from the Internet is somewhat questionable. Additionally, the topic modeling algorithm often requires a degree of active learning, requiring feedback from a domain expert, which in certain circumstances would be ideally minimized. In this work we present Distributed Diverging Latent Dirichlet Allocation (DD-LDA), a novel algorithm for the creation of topic models based on the original Latent Dirichlet Allocation model. The algorithm takes advantage of recent advances in distributed systems approaches to computation, and demonstrates its utility through decreased time requirements as well as increased model performance via the ability to intelligently determine appropriate model size.

Book Synopsis Modeling and Data Mining in Blogosphere by : Nitin Agarwal
Download or read book Modeling and Data Mining in Blogosphere written by Nitin Agarwal and published by Morgan & Claypool Publishers. This book was released on 2009-08-08 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive overview of the various concepts and research issues about blogs or weblogs. It introduces techniques and approaches, tools and applications, and evaluation methodologies with examples and case studies. Blogs allow people to express their thoughts, voice their opinions, and share their experiences and ideas. Blogs also facilitate interactions among individuals creating a network with unique characteristics. Through the interactions individuals experience a sense of community. We elaborate on approaches that extract communities and cluster blogs based on information of the bloggers. Open standards and low barrier to publication in Blogosphere have transformed information consumers to producers, generating an overwhelming amount of ever-increasing knowledge about the members, their environment and symbiosis. We elaborate on approaches that sift through humongous blog data sources to identify influential and trustworthy bloggers leveraging content and network information. Spam blogs or "splogs" are an increasing concern in Blogosphere and are discussed in detail with the approaches leveraging supervised machine learning algorithms and interaction patterns. We elaborate on data collection procedures, provide resources for blog data repositories, mention various visualization and analysis tools in Blogosphere, and explain conventional and novel evaluation methodologies, to help perform research in the Blogosphere.
