Oscar qualifies leads automatically by asking users to put their zip codes into the form fields first. They use the input fields to make sure the website visitor lives in an area where they offer insurance coverage. And if they don’t, a message pops lets the website visitor know.

Natural Language Generation
NER is the technique of identifying named entities in the text corpus and assigning them pre-defined categories such as ‘ person names’ , ‘ locations’ ,’organizations’,etc.. In real life, you will stumble across huge amounts of data in the form of text files. Once the stop words are removed and lemmatization is done ,the tokens we have can be analysed further for information about the text data. The raw text data often referred to as text corpus has a lot of noise. There are punctuation, suffices and stop words that do not give us any information.
As a Gartner survey pointed out, workers who are unaware of important information can make the wrong decisions. To be useful, results must be meaningful, relevant and contextualized. Now, I will walk you through a real-data example of classifying movie reviews as positive or negative. The tokens or ids of probable successive words will be stored in predictions. Now that the model is stored in my_chatbot, you can train it using .train_model() function. When call the train_model() function without passing the input training data, simpletransformers downloads uses the default training data.
Disadvantages of NLP
Jabberwocky is a nonsense poem that doesn’t technically mean much but is still written in a way that can convey some kind of meaning to English speakers. See how “It’s” was split at the apostrophe to give you ‘It’ and “‘s”, but “Muad’Dib” was left whole? This happened because NLTK knows that ‘It’ and “‘s” (a contraction of “is”) are two distinct words, so it counted them separately. But “Muad’Dib” isn’t an accepted contraction like “It’s”, so it wasn’t read as two separate words and was left intact.

Text analytics converts unstructured text data into meaningful data for analysis using different linguistic, statistical, and machine learning techniques. Analysis of these interactions can help brands determine how well a marketing campaign is doing or monitor trending customer issues before they decide how to respond or enhance service for a better customer experience. Additional ways that NLP helps with text analytics are keyword extraction and finding structure or patterns in unstructured text data.

Now, I shall guide through the code to implement this from gensim. Our first step would be to import the summarizer from gensim.summarization. Every token of a spacy model, has an attribute token.label_ which stores the category/ label of each entity. Below code demonstrates how to use nltk.ne_chunk on the above sentence. Let us start with a simple example to understand how to implement NER with nltk .
You mistype a word in a Google search, but it gives you the right search results anyway. It is a way of modern life, something that all of us use, knowingly or unknowingly. Through this blog, we will help you understand the basics of NLP with the help of some real-world NLP application examples. The invention of Carlos Pereira, a father who came up with the application to assist his non-verbal daughter start communicating, is currently available in about 25 languages. After acquiring the information, it can leverage what it understood to come up with decisions or execute an action based on the algorithms.
You can access the dependency of a token through token.dep_ attribute. For better understanding, you can use displacy function of spacy. It is clear that the tokens of this category are not significant. Below example demonstrates how to print all the NOUNS in robot_doc. You see that the keywords are gangtok , sikkkim,Indian and so on. Here, all words are reduced to ‘dance’ which is meaningful and just as required.It is highly preferred over stemming.
I will now walk you through some important methods to implement Text Summarization. From the output of above code, you can clearly see the names of people that appeared in the news. The below code demonstrates how to get a list of all the names in the news . Now that you have understood the base of NER, let me show you how it is useful in real life. Let me show you an example of how to access the children of particular token. For better understanding of dependencies, you can use displacy function from spacy on our doc object.
