Artificial Intelligence has multiple branches, of which Natural language processing (NLP) has emerged as a powerful new-age tool. NLP goes back to the 1950s when Alan Turing released an article – “Computing Machinery and Intelligence” – that proposed a test (now known as the Turing test) involving automated interpretation and generation of natural human languages. Even so, NLP has only recently gained global recognition and popularity.

What is Natural Language Processing?
Natural Language Processing is all about facilitating human-to-machine communications. It aims to train computers to understand, interpret, and manipulate natural human languages. NLP draws inspiration from multiple disciplines such as Artificial Intelligence, Computer Science, and Computational Linguistics.
In-demand Machine Learning Skills
Humans communicate in their native languages such as English, Japanese, Spanish, etc., whereas computers speak in their native language, which is binary language. While computers cannot understand our natural human languages, machine language is mostly incomprehensible to most people.
This is where NLP enters to bridge the gap between human communication and computer understanding. Natural language processing empowers and trains computers to communicate with humans in their native language by helping them read texts, hear speech, interpret audio/text messages, measure sentiment, and much more.
With the explosion of data brought about by the everyday interactions and transactions in the digital world, natural language processing has become more crucial for businesses. Thanks to NLP, companies can harness vast volumes of raw business data, social media chatter, etc., to make sense of data and take data-oriented decisions.

Top GitHub NLP Projects
1. Paraphrase Identification
Paraphrase detection is an NLP application that detects whether or not two different sentences have the same meaning. It is widely used in machine translation, question answering, information extraction/retrieval, text summarization, and natural language generation.
This is a beginner-friendly project wherein you will build a paraphrase identification system that can accurately identify the similarities and differences between two textual entities (for example, sentences) by applying syntactic and semantic analyses on them.
2. Document Similarity
This is another beginner-friendly project that aims to quantify the similarities between two documents by using the Cosine similarity method. By finding the similarities between the two papers, this project will highlight the common topics of discussion.
Cosine similarity converts two documents to vectors to compute the similarity between those vectors. It calculates the document similarities by taking the inner product space that measures the cosine angle between them.
Document similarity mentions the measure of documents with identical intent. Many examples of document similarity in NLP projects use the spaCy module in Python.

In this project, you’ll build an application that can predict the next word as you type words. The tools used to create this text prediction project include Natural Language Processing, Text Mining, and R’s suite of tools.
The project uses a Maximum Likelihood estimator with Kneser Ney Smoothing as the prediction model. The prediction is designed on the collection of words stored in the database used for training the model. You can find the complete set of resources for this project on GitHub.
4. The Science of Genius
This project is a part of the Science of Success project. The aim here is to determine if specific lexical factors can indicate the attention an article received, as measured by normalized citation indices, using a host of data science and NLP analytical tools.
In the initial phases, this project focuses on studying the temporal and disciplinary variance in the length and syntactic features of article titles in the Web of Science – a dataset containing over 50 million articles published since 1900. The bigger picture is to create a quantitative model that can accurately estimate a scientific paper’s impact on the community.
5. Extract stock sentiment from news headlines
As the title suggests, you will use sentiment analysis on financial news headlines from Finviz to produce investing insights in this project. The sentiment analysis technique will help you understand and interpret the emotion behind the headlines and predict whether the present market situation is in favor of a particular stock or not.
6. Intelligent bot
This project involves building a smart bot that can parse and match results from a specific repository to answer questions. The bot uses WordNet for this operation. It weighs the context of a question concerning the tags in structured documents (such as headers, bold titles, etc.). Since it retains the context, you can ask related questions around the same topic.
For instance, if you wish to query a Wikipedia article, you can use the template “Tell me about XYZ” and continue to ask similar questions once the context is established. Again, you can query a webpage by mentioning the page’s URL as the source like “https://www.microsoft.com/en-us/software-download/faq.” This works exceptionally well with FAQ and Q&A pages.
Many tech companies are now using conversational bots, known as Chatbots, to communicate with their customers and solve their concerns. It saves time for both companies and customers. The users are informed first to mention all the details that the bots ask for. The customers are connected to a customer care executive only if human intervention is required in the NLP projects.
This project explains how to use the NLTK library in Python for text preprocessing and text classification. You can also learn how lemmatisation, Tokenization, and Parts-of-Speech tagging are executed in Python. This project familiarises you with the models like Decision trees, Bag-of-words, and Naive Bayes. You can go through an example chatbot application using Python for text classification using NTLK.
It is one of the best NLP projects because chatbots are used in many use cases in the service and hospitality industry. They are used as waiters at the restaurant or assistants for your device. Furthermore, intelligent chatbots are widely adopted for customer service in various sectors. Certain common examples include Alexa, Google Assistant, Siri, etc.

What are the main challenges of Natural language processing?
Natural language processing has a lot of challenges. The major problem is the lack of availability of computational power. The current algorithms are created to run in off-line systems which need huge computational power and may take more time to complete the processing. The other problem is the available resources. Creating an algorithm that can work with a small amount of data is not easy and more time consuming. Another challenge is the availability of huge amounts of data that we need to process.
Which NLP model gives the best accuracy?
The best accuracy for NLP models is achieved by passing the text through a series of increasingly sophisticated filters. The first layer is to remove stop words, punctuation, and numbers. After that, the entire text should be stemmed using a Porter stemmer, then all of the words should be replaced by their lemmatized forms. Then, the final step is to remove any words that do not exist in a vocabulary of 200,000 words.
What is tokenization in NLP?
Tokenization is a process of breaking down a sentence into its constituent parts, called tokens. After applying the process, we can easily extract the meaning or intent of a sentence. Tokenization is done after doing sentence splitting. In NLP, the tokens are used for further processing, classification and representation of the sentence. Some of the NLP tasks that involve tokenization are language detection, POS tagging and parsing.
