Major Challenges of Natural Language Processing NLP

Challenges in Developing Multilingual Language Models in Natural Language Processing NLP by Paul Barba

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. Humans produce so much text data that we do not even realize the value it holds for businesses and society today. We don’t realize its importance because it’s part of our day-to-day lives and easy to understand, but if you input this same text data into a computer, it’s a big challenge to understand what’s being said or happening. NLP machine learning can be put to work to analyze massive amounts of text in real time for previously unattainable insights. This is where training and regularly updating custom models can be helpful, although it oftentimes requires quite a lot of data.

Data availability   Jade finally argued that a big issue is that there are no datasets available for low-resource languages, such as languages spoken in Africa. If we create datasets and make them easily available, such as hosting them on openAFRICA, that would incentivize people and lower the barrier to entry. It is often sufficient to make available test data in multiple languages, as this will allow us to evaluate cross-lingual models and track progress.

More Than Words

The sets of viable states and unique symbols may be large, but finite and known. Few of the problems could be solved by Inference A certain sequence of output symbols, compute the probabilities of one or more candidate states with sequences. Patterns matching the state-switch sequence are most likely to have generated a particular output-symbol sequence. Training the output-symbol chain data, reckon the state-switch/output probabilities that fit this data best.

HMM is not restricted to this application; it has several others such as bioinformatics problems, for example, multiple sequence alignment [128]. Sonnhammer mentioned that Pfam holds multiple alignments and hidden Markov model-based profiles (HMM-profiles) of entire protein domains. HMM may be used for a variety of NLP applications, including word prediction, sentence production, quality assurance, and intrusion detection systems [133].

AI for Air Quality

In the existing literature, most of the work in NLP is conducted by computer scientists while various other professionals have also shown interest such as linguistics, psychologists, and philosophers etc. One of the most interesting aspects of NLP is that it adds up to the knowledge of human language. The field of NLP is related with different theories and techniques that deal with the problem of natural language of communicating with the computers. Some of these tasks have direct real-world applications such as Machine translation, Named entity recognition, Optical character recognition etc.

These days companies strive to keep up with the trends in intelligent process automation. OCR and NLP are the technologies that can help businesses win a host of perks ranging from the elimination of manual data entry to compliance with niche-specific requirements. ABBYY FineReader gradually takes the leading role in document OCR and NLP. This software works with almost 186 languages, including Thai, Korean, Japanese, and others not so widespread ones. ABBYY provides cross-platform solutions and allows running OCR software on embedded and mobile devices. The pitfall is its high price compared to other OCR software available on the market.

As mentioned before, Natural Language Processing is a field of AI that studies the rules and structure of language by combining the power of linguistics and computer science. This creates intelligent systems which operate on machine learning and NLP algorithms and is capable of understanding, interpreting, and deriving meaning from human text and speech. Chat GPT by OpenAI and Bard (Google’s response to Chat GPT) are examples of NLP models that have the potential to transform higher education. These generative language models, i.e., Chat GPT and Google Bard, can generate human-like responses to open-ended prompts, such as questions, statements, or prompts related to academic material. 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. The world has changed a lot in the past few decades, and it continues to change.

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. The problem with naïve bayes is that we may end up with zero probabilities when we meet words in the test data for a certain class that are not present in the training data. Another important challenge that should be mentioned is the linguistic aspect of NLP, like Chat GPT and Google Bard. Emerging evidence in the body of knowledge indicates that chatbots have linguistic limitations (Wilkenfeld et al., 2022). For example, a study by Coniam (2014) suggested that chatbots are generally able to provide grammatically acceptable answers.
