What are the current big challenges in natural language processing and understanding? Artificial Intelligence Stack Exchange

It also has many ambiguities, such as homonyms, synonyms, anaphora, and metaphors. Moreover, language is influenced by the context, the tone, the intention, and the emotion of the speaker or writer. Therefore, you need to ensure that your models can handle the nuances and subtleties of language, that they can adapt to different domains and scenarios, and that they can capture the meaning and sentiment behind the words. Yes, words make up text data, however, words and phrases have different meanings depending on the context of a sentence. Although NLP models are inputted with many words and definitions, one thing they struggle to differentiate is the context.

The technique is highly used in NLP challenges — one of them being to understand the context of words. It can identify that a customer is making a request for a weather forecast, but the location (i.e. entity) is misspelled in this example. By using spell correction on the sentence, and approaching entity extraction with machine learning, it’s still able to understand the request and provide correct service. To be sufficiently trained, an AI must typically review millions of data points. Processing all those data can take lifetimes if you’re using an insufficiently powered PC.

Multilingual NLP in Action

This use case involves extracting information from unstructured data, such as text and images. NLP can be used to identify the most relevant parts of those documents and present them in an organized manner. Natural languages are full of misspellings, typos, and inconsistencies in style. For example, the word “process” can be spelled as either “process” or “processing.” The problem is compounded when you add accents or other characters that are not in your dictionary.

But once it learns the semantic relations and inferences of the question, it will be able to automatically perform the filtering and formulation necessary to provide an intelligible answer, rather than simply showing you data. The extracted information can be applied for a variety of purposes, for example to prepare a summary, to build databases, identify keywords, classifying text items according to some pre-defined categories etc. For example, CONSTRUE, it was developed for Reuters, that is used in classifying news stories (Hayes, 1992) [54]. It has been suggested that many IE systems can successfully extract terms from documents, acquiring relations between the terms is still a difficulty. PROMETHEE is a system that extracts lexico-syntactic patterns relative to a specific conceptual relation (Morin,1999) [89].

Challenges and Solutions in Multilingual NLP

It might not be sufficient for inference and decision making, which are essential for complex problems like multi-turn dialogue. Furthermore, how to combine symbolic processing and neural processing, how to deal with the long tail phenomenon, etc. are also challenges of deep learning for natural language processing. The mission of artificial intelligence (AI) is to assist humans in processing large amounts of analytical data and automate an array of routine tasks.

Here the speaker just initiates the process doesn’t take part in the language generation. 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].

The fourth step to overcome NLP challenges is to evaluate your results and measure your performance. There are many metrics and methods to evaluate NLP models and applications, accuracy, precision, recall, F1-score, BLEU, ROUGE, perplexity, and more. However, these metrics may not always reflect the real-world quality and usefulness of your NLP outputs. Therefore, you should also consider using human evaluation, user feedback, error analysis, and ablation studies to assess your results and identify the areas of improvement.
