Download or read book Exploiting Implicit and Explicit Network Structures for Text Classification written by Poonam Rajiv Bhide and published by . This book was released on 2015 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of text classification is of great importance and has been studied extensively in the field of Computer Science and Machine Learning. Proliferation of digital media has led to collection of massive data in the form of documents, articles, reviews, and news. While these documents contain much important information, it is difficult to manually examine such massive sets of documents and extract the relevant information from each. Every data set has different properties and correlations between its attributes. Network structures formed by correlating some useful attributes can be very helpful for categorizing text. This thesis aims at exploiting the implicit and explicit network structures in legislative bills of the U.S. Congress, to aid in categorizing bill sections. When investigating legislative bills, it becomes clear that bills share a lot of common language. Text reuse amongst bills has resulted in many implicit local alignments amongst bills, where the bill authors do not explicitly mark the content they are copying from previous bills. Many policies also have explicit references to the United States Code. Such implicit and explicit structures in the corpus can aid the text classification of bill sections. An important problem for political scientists aiming to analyze the legislative process is detecting instances of policy proposals. A bill section that either conveys a new policy or changes brought about to an older version of the policy can be classified as a policy idea. On the other hand, statements such as those made in adherence to laws, and references made to historical events or laws are non-policy ideas. The primary evaluation in this thesis is performed on a database of bill sections annotated by political scientists for this kind of policy content. We present analysis of implicit and explicit network structures that may have some impact on the text classification. In future, successful development of efficient classifier algorithm for complex text cases will enable rapid data search and information retrieval. This project aims at contributing in the groundwork for the ongoing research, by taking a classification problem along with network structures.

Download or read book An Introduction to Text Mining written by Gabe Ignatow and published by SAGE Publications. This book was released on 2017-09-22 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Students in social science courses communicate, socialize, shop, learn, and work online. When they are asked to collect data for course projects they are often drawn to social media platforms and other online sources of textual data. There are many software packages and programming languages available to help students collect data online, and there are many texts designed to help with different forms of online research, from surveys to ethnographic interviews. But there is no textbook available that teaches students how to construct a viable research project based on online sources of textual data such as newspaper archives, site user comment archives, digitized historical documents, or social media user comment archives. Gabe Ignatow and Rada F. Mihalcea's new text An Introduction to Text Mining will be a starting point for undergraduates and first-year graduate students interested in collecting and analyzing textual data from online sources, and will cover the most critical issues that students must take into consideration at all stages of their research projects, including: ethical and philosophical issues; issues related to research design; web scraping and crawling; strategic data selection; data sampling; use of specific text analysis methods; and report writing.

Download or read book Open Set Text Classification Using Neural Networks written by Vinodini Molukuvan Venkataram and published by . This book was released on 2018 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a closed set environment, classifiers are trained on examples from a number of known classesandtestedwithunseenexamplesbelongingtothesamesetofknownclasses. However, in most real-world scenarios, a trained classifier is likely to come across novel examples that do not belong to any of the known classes. Such examples should ideally be categorized asbelonging toan unknown class. The goal of an open set classifier isto identify and classify test examples of classes unseen during training. The classifier should be able to declare that a test example belongs to a class it does not know when necessary, and possibly, incorporateitintoitsknowledgeasanexampleofanewclassithasencountered. There is some published research in open set image classification, but open set text classification remains mostly unexplored. In this thesis, we investigate the suitability of various neuralnetworks,viz. ConvolutionalNeuralNetworks(CNNs),RecurrentNeuralNetworks (RNNs), Hierarchical Neural Networks (HNNs) and Hierarchical Neural Networks with Attention, for open set text classification. We find that CNNs are good feature extractors compared to other neural networks and hence perform better than existing state-of-the-art open set classifiers in smaller domains meaning training the classifier on a low number of classes and testing the classifier on a high number of classes (e.g., train on 2 classes and test on 10 classes), although their open set classification abilities in higher domains (e.g., train on 7 classes and test on 10 classes) in general still need to be explored deeper.

Book excerpt: Second, we propose graph representations for the social networks induced from documents and users and apply them on different text classification tasks. Third, we propose social network features extracted from these structures for documents and users. Fourth, we exploit different methods for modeling the social network of communication for four tasks: email classification into business and personal, overt display of power detection in emails, hierarchical power detection in emails, and Reddit post classification. Our main findings are: incorporating the social network information using our proposed methods improves the classification performance for all of the four tasks, and we beat the state-of-the-art graph embedding based model on the three tasks on email; additionally, for the fourth task (Reddit post classification), we argue that simple methods with the proper representation for the task can outperform a state-of-the-art generic model.

Download or read book Sequential Short text Classification with Neural Networks written by Franck Dernoncourt and published by . This book was released on 2017 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Medical practice too often fails to incorporate recent medical advances. The two main reasons are that over 25 million scholarly medical articles have been published, and medical practitioners do not have the time to perform literature reviews. Systematic reviews aim at summarizing published medical evidence, but writing them requires tremendous human efforts. In this thesis, we propose several natural language processing methods based on artificial neural networks to facilitate the completion of systematic reviews. In particular, we focus on short-text classification, to help authors of systematic reviews locate the desired information. We introduce several algorithms to perform sequential short-text classification, which outperform state-of-the-art algorithms. To facilitate the choice of hyperparameters, we present a method based on Gaussian processes. Lastly, we release PubMed 20k RCT, a new dataset for sequential sentence classification in randomized control trial abstracts.

Download or read book Supervised Machine Learning for Text Analysis in R written by Emil Hvitfeldt and published by CRC Press. This book was released on 2021-10-22 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Text data is important for many domains, from healthcare to marketing to the digital humanities, but specialized approaches are necessary to create features for machine learning from language. Supervised Machine Learning for Text Analysis in R explains how to preprocess text data for modeling, train models, and evaluate model performance using tools from the tidyverse and tidymodels ecosystem. Models like these can be used to make predictions for new observations, to understand what natural language features or characteristics contribute to differences in the output, and more. If you are already familiar with the basics of predictive modeling, use the comprehensive, detailed examples in this book to extend your skills to the domain of natural language processing. This book provides practical guidance and directly applicable knowledge for data scientists and analysts who want to integrate unstructured text data into their modeling pipelines. Learn how to use text data for both regression and classification tasks, and how to apply more straightforward algorithms like regularized regression or support vector machines as well as deep learning approaches. Natural language must be dramatically transformed to be ready for computation, so we explore typical text preprocessing and feature engineering steps like tokenization and word embeddings from the ground up. These steps influence model results in ways we can measure, both in terms of model metrics and other tangible consequences such as how fair or appropriate model results are.
