Unlocking the potential of natural language processing: Opportunities and challenges

The biggest challenges in NLP and how to overcome them

This model is called multi-nominal model, in addition to the Multi-variate Bernoulli model, it also captures information on how many times a word is used in a document. Natural language processing (NLP) is a branch of artificial intelligence that deals with understanding or generating human language. NLP has a wide range of real-world applications, such as virtual assistants, text summarization, sentiment analysis, and language translation. The first step to overcome NLP challenges is to understand your data and its characteristics.

In this blog we will discuss the potential of AI/ML and NLP in Healthcare Personalization. We will see how they can be effective in analyzing large amounts of data from various sources, including medical records, genetic information, and social media posts, to identify individualized treatment plans. We will also throw light upon some major apprehensions that Healthcare experts have shown with these technologies, and the workaround that can be employed to tackle them. In Natural Language Processing (NLP) semantics, finding the meaning of a word is a challenge. A knowledge engineer may find it hard to solve the meaning of words have different meanings, depending on their use.

Modular Deep Learning

Powerful as it may be, it has quite a few limitations, the first of which is the fact that humans have unconscious biases that distort their understanding of the information. This form of confusion or ambiguity is quite common if you rely on non-credible NLP solutions. As far as categorization is concerned, ambiguities can be segregated as Syntactic (meaning-based), Lexical (word-based), and Semantic (context-based). Startups planning to design and develop chatbots, voice assistants, and other interactive tools need to rely on NLP services and solutions to develop the machines with accurate language and intent deciphering capabilities.

Therefore, you need to ensure that you have a clear data strategy, that you source data from reliable and diverse sources, that you clean and preprocess data properly, and that you comply with the relevant laws and ethical standards. This is where NLP (Natural Language Processing) comes into play — the process used to help computers understand text data. Learning a language is already hard for us humans, so you can imagine how difficult it is to teach a computer to understand text data. With spoken language, mispronunciations, different accents, stutters, etc., can be difficult for a machine to understand. However, as language databases grow and smart assistants are trained by their individual users, these issues can be minimized.

Overcoming the Top 3 Challenges to NLP Adoption

The sixth and final step to overcome NLP challenges is to be ethical and responsible in your NLP projects and applications. NLP can have a huge impact on society and individuals, both positively and negatively. Therefore, you should be aware of the potential risks and implications of your NLP work, such as bias, discrimination, privacy, security, misinformation, and manipulation.


So, for building NLP systems, it’s important to include all of a word’s possible meanings and all possible synonyms. Text analysis models may still occasionally make mistakes, but the more relevant training data they receive, the better they will be able to understand synonyms. The following is a list of some of the most commonly researched tasks in natural language processing. Some of these tasks have direct real-world applications, while others more commonly serve as subtasks that are used to aid in solving larger tasks. I will just say improving the accuracy in fraction is a real challenge now . People are doing Phd in machine translation , some of them are working for improving the algorithms behind the translation and some of them are working to improve and enlarge the training data set ( Corpus ).

High-quality and diverse training data are essential for the success of Multilingual NLP models. Ensure that your training data represents the linguistic diversity you intend to work with. Data augmentation techniques can help overcome data scarcity for some languages.

Here – in this grossly exaggerated example to showcase our technology’s ability – the AI is able to not only split the misspelled word “loansinsurance”, but also correctly identify the three key topics of the customer’s input. It then automatically proceeds with presenting the customer with three distinct options, which will continue the natural flow of the conversation, as opposed to overwhelming the limited internal logic of a chatbot. When a customer asks for several things at the same time, such as different products, boost.ai’s conversational AI can easily distinguish between the multiple variables.

Choosing the right language model for your NLP use case

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. AI machine learning NLP applications have been largely built for the most common, widely used languages. And it’s downright amazing at how accurate translation systems have become. However, many languages, especially those spoken by people with less access to technology often go overlooked and under processed.

  • Data is the fuel of NLP, and without it, your models will not perform well or deliver accurate results.
  • They have categorized sentences into 6 groups based on emotions and used TLBO technique to help the users in prioritizing their messages based on the emotions attached with the message.
  • Peter Wallqvist, CSO at RAVN Systems commented, “GDPR compliance is of universal paramountcy as it will be exploited by any organization that controls and processes data concerning EU citizens.
  • For example, Australia is fairly lax in regards to web scraping, as long as it’s not used to gather email addresses.
  • When a student submits a question or response, the model can analyze the input and generate a response tailored to the student’s needs.

With advancements in deep learning and neural machine translation models, such as Transformer-based architectures, machine translation has seen remarkable improvements in accuracy and fluency. Multilingual Natural Language Processing models can translate text between many language pairs, making cross-lingual communication more accessible. 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. There are challenges of deep learning that are more common, such as lack of theoretical foundation, lack of interpretability of model, and requirement of a large amount of data and powerful computing resources. There are also challenges that are more unique to natural language processing, namely difficulty in dealing with long tail, incapability of directly handling symbols, and ineffectiveness at inference and decision making.

Lexical level ambiguity refers to ambiguity of a single word that can have multiple assertions. Each of these produce ambiguities that can be solved by the knowledge of the complete sentence. The ambiguity can be solved by various methods such as Minimizing Ambiguity, Preserving Ambiguity, Interactive Disambiguation and Weighting Ambiguity [125].

Since all the users may not be well-versed in machine specific language, Natural Language Processing (NLP) caters those users who do not have enough time to learn new languages or get perfection in it. In fact, NLP is a tract of Artificial Intelligence and Linguistics, devoted to make computers understand the statements or words written in human languages. It came into existence to ease the user’s work and to satisfy the wish to communicate with the computer in natural language, and can be classified into two parts i.e.
