Introduction
In the field of natural language processing, entity detection plays a crucial role in extracting meaningful information from textual data. Identifying entities with specific characteristics can provide valuable insights for various applications. In this assignment, we will focus on implementing PySpark code using DataFrames, RDDs, or Spark UDF functions to find entities with names that are palindromes.
Problem Statement
The task at hand is to identify companies whose names read the same way forward and backward, known as palindromes. We will be working with a subset of a dataset containing information about companies. The dataset includes three columns: the name of the company, the city it's located in, and its website domain. By leveraging the power of PySpark, we aim to identify and extract all entities whose names are palindromes.
Implementation Details
To solve this problem, we will be utilizing Google Colab, which provides a powerful environment for running PySpark code. PySpark is the Python API for Apache Spark, a widely-used distributed computing framework for big data processing.
We will start by loading the dataset into a Spark DataFrame, which provides a structured representation of the data. With DataFrames, we can easily manipulate and process the data using Spark's distributed computing capabilities.
Next, we will define a Spark UDF (User-Defined Function) to check whether a given name is a palindrome. The UDF will take a string as input and return a Boolean value indicating whether the string is a palindrome. This UDF will be applied to the "name" column of the DataFrame to identify palindromic entities.
Once we have applied the UDF to the "name" column, we will filter the DataFrame to retain only the rows where the name is a palindrome. This will give us a new DataFrame containing only the entities with palindromic names.
To provide insights into the results, we will print the count of palindromic entities and display the resulting Spark DataFrame using the show() function. This will allow us to examine the extracted entities and their associated information, such as the city and website domain.
