Keywords

💡Plagiarism Detector

A plagiarism detector is a software tool designed to identify and prevent instances of plagiarism in written work. In the context of the video, the creator is discussing the development of such a tool using Python. This tool is crucial for educational institutions and publishers to ensure academic integrity and originality in submitted documents.

💡Natural Language Processing (NLP)

Natural Language Processing is a field of artificial intelligence that focuses on the interaction between computers and humans through natural language. In the video, NLP is used to process text data for the plagiarism checker, helping to understand and analyze the language in a way that is both meaningful and useful for detecting similarities between documents.

💡Python

Python is a high-level programming language known for its readability and versatility. The video script mentions Python as the programming language used to develop the plagiarism detector. It is chosen for its extensive library support and community, which simplifies the development of complex applications like a plagiarism checker.

💡Requirements

In software development, 'requirements' refer to the specific conditions or capabilities that a program must meet or possess. The script mentions a 'requirements' file, which likely contains a list of all necessary libraries and dependencies needed for the plagiarism detector to function properly.

💡Dependency

A dependency in programming is a software package or library that another piece of software relies on to function. The video discusses installing dependencies using 'pip install', which are crucial for the plagiarism checker to operate correctly, such as NLP libraries.

Unicode is a computing standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The script mentions using Unicode to remove non-alphanumeric characters from text, which is a preprocessing step for the plagiarism detection process.

💡API

An API, or Application Programming Interface, is a set of routines, protocols, and tools for building software applications. The video discusses using an API for web search, which might be employed to compare documents against a vast database of online content to check for plagiarism.

💡Sentiment Analysis

Sentiment analysis, also known as opinion mining, is the process of determining whether a piece of writing is positive, negative, or neutral. While not directly related to plagiarism detection, the video mentions future plans to release a sentiment analysis tool, indicating an expansion into other areas of natural language processing.

💡Error Handling

Error handling is the process of responding to the many types of exceptions that can occur during the execution of a software program. The script describes encountering and resolving errors such as 'no model found in the discovery' and 'permission issues', which are common challenges in the development process.
