Speech Title: Types of Text Clustering and Text Encoding Schemes
Abstract: This tutorial is concerned with the modifications of machine learning algorithms for processing textual data. Among tasks of processing symbolic data, we set the text classification as the scope of this tutorial, and explore the various types of classification tasks. In this tutorial, we describe the process of encoding texts into tables, string vectors, and graphs as well as numerical vectors as the structured forms. We present the schemes of modifying the machine learning algorithms such as k nearest neighbor, Naïve Bayes, learning vector quantization, and perceptron, into the version which can receive the alternative structured forms to numerical vectors as the input data. Therefore, the goal of this research is to improve the word classification performance by solving problems such as dimensionality and sparse distribution in encoding textual data into numerical vectors.
