10 Major Challenges of Using Natural Language Processing

In the recent past, models dealing with Visual Commonsense Reasoning [31] and NLP have also been getting attention of the several researchers and seems a promising and challenging area to work upon. Santoro et al. [118] introduced a rational recurrent neural network with the capacity to learn on classifying the information and perform complex reasoning based on the interactions between compartmentalized information. Finally, the model was tested for language modeling on three different datasets (GigaWord, Project Gutenberg, and WikiText-103).

A good way to visualize this information is using a Confusion Matrix, which compares the predictions our model makes with the true label. Ideally, the a diagonal line from top left to bottom right (our predictions match the truth perfectly). Xie et al. [154] proposed a neural architecture where candidate answers and their representation learning are constituent centric, guided by a parse tree.

After training the same model a third time (a Logistic Regression), we get an accuracy score of 77.7%, our best result yet! Whenever it comes to classifying data, a common favorite for its versatility and explainability is Logistic Regression. The vector will contain mostly 0s because each sentence contains only a very small subset of our vocabulary. We wrote this post as a step-by-step guide; it can also serve as a high level overview of highly effective standard approaches.

Further, Natural Language Generation (NLG) is the process of producing phrases, sentences and paragraphs that are meaningful from an internal representation. The first objective of this paper is to give insights of the various important terminologies of NLP and NLG. Using these approaches is better as classifier is learned from training data rather than making by hand. The naïve bayes is preferred because of its performance despite its simplicity (Lewis, 1998) [67] In Text Categorization two types of models have been used (McCallum and Nigam, 1998) [77]. But in first model a document is generated by first choosing a subset of vocabulary and then using the selected words any number of times, at least once irrespective of order.

Training the output-symbol chain data, reckon the state-switch/output probabilities that fit this data best. Natural Language Processing can be applied into various areas like Machine Translation, Email Spam detection, Information Extraction, Summarization, Question Answering etc. Next, we discuss some of the areas with the relevant work done in those directions.

The science of extracting meaning and learning from text data is an active topic of research called Natural Language Processing (NLP). However, skills are not available in the right demographics to address these problems. What we should focus on is to teach skills like machine translation in order to empower people to solve these problems. Academic progress unfortunately doesn’t necessarily relate to low-resource languages.

Challenges of NLP

Real-world examples of NLU include small tasks like issuing short commands based on text comprehension to some small degree like redirecting an email to the right receiver based on basic syntax and decently sized lexicon. While this may seem trivial, it can have a profound impact on a chatbot’s ability to carry on a successful conversation with a user. The same problems that plague our day-to-day communication with other humans via text can, and likely will, impact our interactions with chatbots. Examples of these issues include spelling and grammatical errors and poor language use in general. Advanced Natural Language Processing (NLP) capabilities can identify spelling and grammatical errors and allow the chatbot to interpret your intended message despite the mistakes. Some of the other challenges that make NLP difficult to scale are low-resource languages and lack of research and development.

NLP machine learning can be put to work to analyze massive amounts of text in real time for previously unattainable insights. It mainly focuses on the literal meaning of words, phrases, and sentences. POS stands for parts of speech, which includes Noun, verb, adverb, and Adjective. It indicates that how a word functions with its meaning as well as grammatically within the sentences. A word has one or more parts of speech based on the context in which it is used. It is used for extracting structured information from unstructured or semi-structured machine-readable documents.

In this tutorial, we will use BERT to develop your own text classification model.

Artificial intelligence is all set to bring desired changes in the business-consumer relationship scene. NLP makes any chatbot better and more relevant for contemporary use, considering how other technologies are evolving and how consumers are using them to search for brands. Unless the speech designed for it is convincing enough to actually retain the user in a conversation, the chatbot will have no value. Therefore, the most important component of an NLP chatbot is speech design. In addition, the existence of multiple channels has enabled countless touchpoints where users can reach and interact with.

• So, it is important to understand various important terminologies of NLP and different levels of NLP.
• The naïve bayes is preferred because of its performance despite its simplicity (Lewis, 1998) [67] In Text Categorization two types of models have been used (McCallum and Nigam, 1998) [77].
• Dependency Parsing is used to find that how all the words in the sentence are related to each other.
• This offers a great opportunity for companies to capture strategic information such as preferences, opinions, buying habits, or sentiments.
• Whenever it comes to classifying data, a common favorite for its versatility and explainability is Logistic Regression.

NLG techniques provide ideas on how to build symbiotic systems that can take advantage of the knowledge and capabilities of both humans and machines. Needless to say, for a business with a presence in multiple countries, the services need to be just as diverse. An NLP chatbot that is capable of understanding and conversing in various languages makes for an efficient solution for customer communications. This also helps put a user in his comfort zone so that his conversation with the brand can progress without hesitation. Today, chatbots do more than just converse with customers and provide assistance – the algorithm that goes into their programming equips them to handle more complicated tasks holistically.

Examples of Natural Language Processing in Action

It stores the history, structures the content that is potentially relevant and deploys a representation of what it knows. All these forms the situation, while selecting subset of propositions that speaker has. The only requirement is the speaker must make sense of the situation [91].

NLP based chatbots not only increase growth and profitability but also elevate customer experience to the next level all the while smoothening the business processes. Together with Artificial Intelligence/ Cognitive Computing, NLP makes it possible to easily comprehend the meaning of words in the context in which they appear, considering also abbreviations, acronyms, slang, etc. This offers a great opportunity for companies to capture strategic information such as preferences, opinions, buying habits, or sentiments. Companies can utilize this information to identify trends, detect operational risks, and derive actionable insights.

Earlier machine learning techniques such as Naïve Bayes, HMM etc. were majorly used for NLP but by the end of 2010, neural networks transformed and enhanced NLP tasks by learning multilevel features. Major use of neural networks in NLP is observed for word embedding where words are represented in the form of vectors. Initially focus was on feedforward [49] and CNN (convolutional neural network) architecture [69] but later researchers adopted recurrent neural networks to capture the context of a word with respect to surrounding words of a sentence.
