i OOP in Python ii About the Tutorial Python has been an object-oriented language since it existed. In this tutorial we will try to get in-depth features of OOPS in Python programming 1 What is Object Oriented Programming? .......................................................................................................... 2 Why to Choose Object-oriented programming?...... Procedural vs. Object Oriented Programming .................................................................................................. 2 Principles of Object Oriented Programming ...........

Construction A Conceptual Knowledge Graph oriented News Data Domain-specific Knowledge Graph Construction A Conceptual Knowledge Graph oriented News Data Motivation With the emergence of massive connecting significant insights from these massive unstructured texts. A Conceptual Knowledge Graph oriented News Data How to mine and organize meaningful concepts and their semantic connections from a set rather than having a collection of relevant documents. Motivation A Conceptual Knowledge Graph oriented News Data We present a system that extracts salient entities, concepts, and their relationships
