What is NLP? How it Works, Benefits, Challenges, Examples

Machine learning requires A LOT of data to function to its outer limits – billions of pieces of training data. That said, data (and human language!) is only growing by the day, as are new machine learning techniques and custom algorithms. All of the problems above will require more research and new techniques in order to improve on them. AI machine learning NLP applications have been largely built for the most common, widely used languages.

The main difference between Stemming and lemmatization is that it produces the root word, which has a meaning. Implementing the Chatbot is one of the important applications of NLP. It is used by many companies to provide the customer’s chat services.

We will provide a couple of examples of NLP use cases and tell you about its most remarkable achievements, future trends, and the challenges it faces. More complex models for higher-level tasks such as question answering on the other hand require thousands of training examples for learning. Transferring tasks that require actual natural language understanding from high-resource to low-resource languages is still very challenging. With the development of cross-lingual datasets for such tasks, such as XNLI, the development of strong cross-lingual models for more reasoning tasks should hopefully become easier. Several companies in BI spaces are trying to get with the trend and trying hard to ensure that data becomes more friendly and easily accessible. But still there is a long way for this.BI will also make it easier to access as GUI is not needed.

Week one will include over 50 unique sessions, with a special track on NLP in healthcare. Week two will feature beginner to advanced training workshops with certifications. Text classification is used to assign an appropriate category to the text. As you may have seen, articles on news websites are often divided into categories. Such categorization is usually done automatically with the help of text classification algorithms. Linguistics is a broad subject that includes many challenging categories, some of which are Word Sense Ambiguity, Morphological challenges, Homophones challenges, and Language Specific Challenges (Ref.1).

Discriminative methods are more functional and have right estimating posterior probabilities and are based on observations. Srihari [129] explains the different generative models as one with a resemblance that is used to spot an unknown speaker’s would bid the deep knowledge of numerous languages to perform the match. Discriminative methods rely on a less knowledge-intensive approach and using distinction between languages. Whereas generative models can become troublesome when many features are used and discriminative models allow use of more features [38]. Few of the examples of discriminative methods are Logistic regression and conditional random fields (CRFs), generative methods are Naive Bayes classifiers and hidden Markov models (HMMs).

Consumers today have learned to use voice search tools to complete a search task. Since the SEO that businesses base their marketing on depends on keywords, with voice-search, the keywords have also changed. Chatbots are now required to “interpret” user intention from the voice-search terms and respond accordingly with relevant answers. These are easy for humans to understand because we read the context of the sentence and we understand all of the different definitions. And, while NLP language models may have learned all of the definitions, differentiating between them in context can present problems.

Now you can guess if there is a gap in any of the them it will effect the performance overall in chatbots . Now resolving the association of word ( Pronoun) ‘he’ with Rahul and sukesh could be a challenge not necessarily . Its just an example to make you understand .What are current NLP challenge in Coreference resolution. You must have played around the Google Translate , If not first go and play with Google Translate .It can translate the text from one language to another .
