It also helps to quickly find relevant information from databases containing millions of documents in seconds. An NLP-generated document accurately summarizes any original text that humans can’t automatically generate. Also, it can carry out repetitive tasks such as analyzing large chunks of data to improve human efficiency.

The second objective of this paper focuses on the history, applications, and recent developments in the field of NLP. The third objective is to discuss datasets, approaches and evaluation metrics used in NLP. The relevant work done in the existing literature with their findings and some of the important applications and projects in NLP are also discussed in the paper. The last two objectives may serve as a literature survey for the readers already working in the NLP and relevant fields, and further can provide motivation to explore the fields mentioned in this paper.

Increased documentation efficiency & accuracy

How much can it actually understand what a difficult user says, and what can be done to keep the conversation going? These are some of the questions every company should ask before deciding on how to automate customer interactions. Some phrases and questions actually have multiple intentions, so your NLP system can’t oversimplify the situation by interpreting only one of those intentions. For example, a user may prompt your chatbot with something like, “I need to cancel my previous order and update my card on file.” Your AI needs to be able to distinguish these intentions separately.

  • As Multilingual NLP grows, ethical considerations related to bias, fairness, and cultural sensitivity will become even more prominent.
  • Unstructured data directly reflects the interests, feelings, opinions and knowledge of customers, employees, patients, citizens, etc.
  • The third objective is to discuss datasets, approaches and evaluation metrics used in NLP.
  • Finally, NLP models are often language-dependent, so businesses must be prepared to invest in developing models for other languages if their customer base spans multiple nations.
  • However, applying NLP to a business can present a number of key challenges.

In this section, we’ll explore real-world applications that showcase the transformative power of Multilingual Natural Language Processing (NLP). From breaking down language barriers to enabling businesses and individuals to thrive in a globalized world, Multilingual NLP is making a tangible impact across various domains. The fifth task, the sequential decision process such as the Markov decision process, is the key issue in multi-turn dialogue, as explained below. It has not been thoroughly verified, however, how deep learning can contribute to the task. On the other hand, for reinforcement learning, David Silver argued that you would ultimately want the model to learn everything by itself, including the algorithm, features, and predictions.

Ontology-guided extraction of structured information from unstructured text: Identifying and capturing complex relationships

Naive Bayes is a probabilistic algorithm which is based on probability theory and Bayes’ Theorem to predict the tag of a text such as news or customer review. It helps to calculate the probability of each tag for the given text and return the tag with the highest probability. Bayes’ Theorem is used to predict the probability of a feature based on prior knowledge of conditions that might be related to that feature. Anggraeni et al. (2019) [61] used ML and AI to create a question-and-answer system for retrieving information about hearing loss. They developed I-Chat Bot which understands the user input and provides an appropriate response and produces a model which can be used in the search for information about required hearing impairments.

In order to resolve this, an NLP system must be able to seek context to help it understand the phrasing. Different languages have not only vastly different sets of vocabulary, but also different types of phrasing, different modes of inflection, and different cultural expectations. You can resolve this issue with the help of “universal” models that can transfer at least some learning to other languages. However, you’ll still need to spend time retraining your NLP system for each language.

Domain-specific language

Say your sales department receives a package of documents containing invoices, customs declarations, and insurances. Parsing each document from that package, you run the risk to retrieve wrong information. A word, number, date, special character, or any meaningful element can be a token. It is a plain text free of specific fonts, diagrams, or elements that make it difficult for machines to read a document line by line.

  • Bayes’ Theorem is used to predict the probability of a feature based on prior knowledge of conditions that might be related to that feature.
  • Statistical models are good for general and scalable tasks, but they require a lot of data and may not capture the nuances and contexts of natural languages.
  • AI needs continual parenting over time to enable a feedback loop that provides transparency and control.
  • An NLP system can be trained to summarize the text more readably than the original text.
  • A language can be defined as a set of rules or set of symbols where symbols are combined and used for conveying information or broadcasting the information.
  • Moreover, it is not necessary that conversation would be taking place between two people; only the users can join in and discuss as a group.

Therefore, the use of NLP models in higher education expands beyond the aforementioned examples, with new applications being developed to aid students in their academic pursuits. Natural language processing (NLP) is a field of artificial intelligence (AI) that focuses on understanding and interpreting human language. It is used to develop software and applications that can comprehend and respond to human language, making interactions with machines more natural and intuitive. NLP is an incredibly complex and fascinating field of study, and one that has seen a great deal of advancements in recent years. A third challenge of NLP is choosing and evaluating the right model for your problem. There are many types of NLP models, such as rule-based, statistical, neural, or hybrid ones.

Videos and images as user-generated content are quickly becoming mainstream, which in turn means that our technology needs to adapt. Eight of the 13 colonoscopy quality measures were extracted with high performance, achieving F measures ≥ 0.90 at each site (12 of 13 were ≥ 0.85 at each site), and F measures were ≥ 0.95 for detection of any adenoma (Table 2). Overall, performance on pathology-based metrics was higher than on colonoscopy-based metrics. We take our mission of to quality education seriously.

Add-on sales and a feeling of proactive service for the customer provided in one swoop. In the event that a customer does not provide enough details in their initial query, the conversational AI is able to extrapolate from the request and probe for more information. The new information it then gains, combined with the original query, will then be used to provide a more complete answer. The dreaded response that usually kills any joy when talking to any form of digital customer interaction.


In summary, there are still a number of open challenges with regard to deep learning for natural language processing. Deep learning, when combined with other technologies (reinforcement learning, inference, knowledge), may further push the frontier of the field. We think that, among the advantages, end-to-end training and representation learning really differentiate deep learning from traditional machine learning approaches, and make it powerful machinery for natural language processing. Cross-lingual representations   Stephan remarked that not enough people are working on low-resource languages. There are 1,250-2,100 languages in Africa alone, most of which have received scarce attention from the NLP community.

Unstructured data directly reflects the interests, feelings, opinions and knowledge of customers, employees, patients, citizens, etc. All these manual work is performed because we have to convert unstructured data to structured one . Using the sentiment extraction technique companies can import all user reviews and machine can extract the sentiment on the top of it .

Natural Language Processing (NLP) Challenges

Natural Language Processing (NLP) is a subfield of artificial intelligence (AI). It enables robots to analyze and comprehend human language, enabling them to carry out repetitive activities without human intervention. Examples include machine translation, summarization, ticket classification, and spell check.

This can help set more realistic expectations for the likely returns from new projects. Our recent state-of-the-industry report on NLP found that most—nearly 80%— expect to spend more on NLP projects in the next months. Yet, organizations still face barriers to the development and implementation of NLP models.

The fifth step to overcome NLP challenges is to keep learning and updating your skills and knowledge. NLP is a fast-growing and dynamic field that constantly evolves and innovates. New research papers, models, tools, and applications are published and released every day.
