Applied Sciences Special Issue : Natural Language Processing: Trends and Challenges

In fact, a large amount of knowledge for natural language processing is in the form of symbols, including linguistic knowledge (e.g. grammar), lexical knowledge (e.g. WordNet) and world knowledge (e.g. Wikipedia). Currently, deep learning methods have not yet made effective use of the knowledge. Symbol representations are easy to interpret and manipulate and, on the other hand, vector representations are robust to ambiguity and noise.

There are still lots of other use cases for speech recognition like transcription services or voice-controlled devices. Remember about the feature that allows drivers to control cars safely hands-free. 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. Implement analytics tools to continuously monitor the performance of NLP applications.

Challenges

CRAG doesn’t stop at mere acknowledgment when the evaluation deems the retrieved documents suboptimal. Instead, it employs a sophisticated decompose-recompose algorithm, selectively focusing on the crux of the retrieved information while discarding the chaff. This ensures that only the most relevant, accurate knowledge is integrated into the generation process. Moreover, CRAG embraces the vastness of the web, utilizing large-scale searches to augment its knowledge base beyond static, limited corpora.

Today, NLP tends to be based on turning natural language into machine language. But with time the technology matures – especially the AI component –the computer will get better at “understanding” the query and start to deliver answers rather than search results. Initially, the data chatbot will probably ask the question ‘how have revenues changed over the last three-quarters?

Next, we discuss some of the areas with the relevant work done in those directions. NLP can be classified into two parts i.e., Natural Language Understanding and Natural Language Generation which evolves the task to understand and generate the text. The objective of this section is to discuss the Natural Language Understanding (Linguistic) (NLU) and the Natural Language Generation (NLG). Although rule-based systems for manipulating symbols were still in use in 2020, they have become mostly obsolete with the advance of LLMs in 2023.

• Table 2 shows the performances of example problems in which deep learning has surpassed traditional approaches.
• 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].
• It has not been thoroughly verified, however, how deep learning can contribute to the task.
• The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).
• It is often possible to perform end-to-end training in deep learning for an application.

Linguistics is the science of language which includes Phonology that refers to sound, Morphology word formation, Syntax sentence structure, Semantics syntax and Pragmatics which refers to understanding. Noah Chomsky, one of the first linguists of twelfth century that started syntactic theories, marked a unique position in the field of theoretical linguistics because he revolutionized the area of syntax (Chomsky, 1965) [23]. 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.

Homonyms – two or more words that are pronounced the same but have different definitions – can be problematic for question answering and speech-to-text applications because they aren’t written in text form. The earliest decision trees, producing systems of hard if–then rules, were still very similar to the old rule-based approaches. Only the introduction of hidden Markov models, applied to part-of-speech tagging, announced the end of the old rule-based approach.

From creating captions for posts to generating content ideas to writing posts, the tool helps social media professionals beat writer’s block and work more efficiently. Unlike regular chatbots, Lyro doesn’t require any training from support agents — the company activates it and starts responding to users’ natural language processing challenges queries right away. It also covers NLP’s objectives, challenges, and latest research developments. Establish feedback mechanisms to gather insights from users of the NLP system. Use this feedback to make adaptive changes, ensuring the solution remains effective and aligned with business goals.

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. There are particular words in the document that refer to specific entities or real-world objects like location, people, organizations etc.

Autocorrect and grammar correction applications can handle common mistakes, but don’t always understand the writer’s intention. Ambiguity in NLP refers to sentences and phrases that potentially have two or more possible interpretations.

Enhancing the Accuracy of Large Language Models with Corrective Retrieval Augmented Generation (CRAG)

Deep learning certainly has advantages and challenges when applied to natural language processing, as summarized in Table 3. This editorial first provides an overview of the field of NLP in terms of research grants, publication venues, and research topics. 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. These models try to extract the information from an image, video using a visual reasoning paradigm such as the humans can infer from a given image, video beyond what is visually obvious, such as objects’ functions, people’s intents, and mental states. NLU enables machines to understand natural language and analyze it by extracting concepts, entities, emotion, keywords etc. It is used in customer care applications to understand the problems reported by customers either verbally or in writing.
