Feature selection based on a normalized difference measure for text classification

Feature selection based on a normalized difference measure for text classification Feature selection based on a normalized difference measure for text classification   a b s t r a c t The goal of feature selection in text classification is to choose highly distinguishing fea- tures for improving the performance of a classifier. The well-known text classification fea- ture selection metric named balanced accuracy measure (ACC2) (Forman, 2003) evaluates a term by taking the difference of its document frequency in the positive class…

Classification of text documents based on score level fusion approach

Classification of text documents based on score level fusion approach Classification of text documents based on score level fusion approach   a b s t r a c t Text document classification is a well known theme in the field of the information retrieval and text min- ing. Selection of most desired features in the text document plays a vital role in classification problem. This research article addresses the problem of text classification by considering Sentence–Vector Space Model (S-VSM) and Unigram representation models…

A feature selection model based on genetic rank aggregation for text sentiment classification

A feature selection model based on genetic rank aggregation for text sentiment classification A feature selection model based on genetic rank aggregation for text sentiment classification   Abstract Sentiment analysis is an important research direction of natural language processing, text mining and web mining which aims to extract subjective information in source materials. The main challenge encountered in machine learning method-based sentiment classification is the abundant amount of data available. This amount makes it difficult to train the learning algorithms in a feasible…

TERM-WEIGHTING APPROACHES IN AUTOMATIC TEXT RETRIEVAL

TERM-WEIGHTING APPROACHES IN AUTOMATIC TEXT RETRIEVAL TERM-WEIGHTING APPROACHES IN AUTOMATIC TEXT RETRIEVAL   Abstract- The experimental evidence accumulated over the past 20 years indicates that text indexing systems based on the assignment of appropriately weighted single terms produce retrieval results that are superior to those obtainable with other more elaborate text representations. These results depend crucially on the choice of effective term weighting systems. This article summarizes the insights gained in automatic term weighting, and provides baseline single-term-indexing models with which other more…

Machine Learning in Automated Text Categorization

Machine Learning in Automated Text Categorization Machine Learning in Automated Text Categorization Abstract: The automated categorization (or classification) of texts into predefined categories has witnessed a booming interest in the last 10 years, due to the increased availability of documents in digital form and the ensuing need to organize them. In the research community the dominant approach to this problem is based on machine learning techniques: a general inductive process automatically builds a classifier by learning, from a set of preclassified documents, the…

Artificial intelligence projects using matlab in iran Artificial intelligence projects using matlab in iran Artificial intelligence (AI, also machine intelligence, MI) is apparently intelligent behaviour by machines, rather than the natural intelligence (NI) of humans and other animals. In computer science AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem solving".…
