Enhancing the Accuracy of Large Language Models with Corrective Retrieval Augmented Generation CRAG
Sonnhammer mentioned that Pfam holds multiple alignments and hidden Markov model-based profiles (HMM-profiles) of entire protein domains. The cue of domain boundaries, family members and alignment are done semi-automatically found on expert knowledge, sequence similarity, other protein family databases and the capability of HMM-profiles to correctly identify and align the members. HMM may be used for a variety of NLP applications, including word prediction, sentence production, quality assurance, and intrusion detection systems . Wiese et al.  introduced a deep learning approach based on domain adaptation techniques for handling biomedical question answering tasks.
Most of the problems in natural language processing can be formalized as these five tasks, as summarized in Table 1. In the tasks, words, phrases, sentences, paragraphs and even documents are usually viewed as a sequence of tokens (strings) and treated similarly, although they have different complexities. Several companies in BI spaces are trying to get with the trend and trying hard to ensure that data becomes more friendly and easily accessible. But still there is a long way for this.BI will also make it easier to access as GUI is not needed. Because nowadays the queries are made by text or voice command on smartphones.one of the most common examples is Google might tell you today what tomorrow’s weather will be. But soon enough, we will be able to ask our personal data chatbot about customer sentiment today, and how we feel about their brand next week; all while walking down the street.

AI machine learning NLP applications have been largely built for the most common, widely used languages. However, many languages, especially those spoken by people with less access to technology often go overlooked and under processed. For example, by some estimations, (depending on language vs. dialect) there are over 3,000 languages in Africa, alone.
Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website.

Merity et al.  extended conventional word-level language models based on Quasi-Recurrent Neural Network and LSTM to handle the granularity at character and word level.
A Meme’s Glimpse into the Pinnacle of Artificial Intelligence (AI) Progress in a Mamba…
The key driving factors for NLP adoption were improvements in computational power, advancements in AI and machine learning, and data availability. The latter occurred largely because of the cloud, which provided better scalability and lower costs for data storage and processing. Addressing these challenges requires not only technological innovation but also a multidisciplinary approach that considers linguistic, cultural, ethical, and practical aspects.
So, it will be interesting to know about the history of NLP, the progress so far has been made and some of the ongoing projects by making use of NLP. The third objective of this paper is on datasets, approaches, evaluation metrics and involved challenges in NLP. Section 2 deals with the first objective mentioning the various important terminologies of NLP and NLG. Section 3 deals with the history of NLP, applications of NLP and a walkthrough of the recent developments. Datasets used in NLP and various approaches are presented in Section 4, and Section 5 is written on evaluation metrics and challenges involved in NLP. Natural language processing (NLP) is an interdisciplinary subfield of computer science and linguistics.
We discussed the biggest use cases but left out smaller ones like autocorrect and autocomplete features, fraud detection, etc. To make our research fuller, let’s speak about real-life examples of how NLP transforms industries. Search engines like Google use NLP to improve the accuracy of their search results. This approach helps to understand the user intent behind the query better and match it with the most relevant search results.
It’s task was to implement a robust and multilingual system able to analyze/comprehend medical sentences, and to preserve a knowledge of free text into a language independent knowledge representation [107, 108]. 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 combination and integration of these components allow data scientists to build powerful NLP systems and contribute to better AI communication results.

Its market size was valued at $18.9 billion in 2023 and is expected to grow to $68 billion by 2028. Nothing’s surprising about this, regarding the diverse applications of NLP in the modern-day world, from chatbots to machine translation to document analysis. 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. Table 2 shows the performances of example problems in which deep learning has surpassed traditional approaches. Among all the NLP problems, progress in machine translation is particularly remarkable.
LSTM (Long Short-Term Memory), a variant of RNN, is used in various tasks such as word prediction, and sentence topic prediction.  In order to observe the word arrangement in forward and backward direction, bi-directional LSTM is explored by researchers . In case of machine translation, encoder-decoder architecture is used where dimensionality of input and output vector is not known. Neural networks can be used to anticipate a state that has not yet been seen, such as future states for which predictors exist whereas HMM predicts hidden states. 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.
- As a result, we can calculate the loss at the pixel level using ground truth.
- Some of these tasks have direct real-world applications such as Machine translation, Named entity recognition, Optical character recognition etc.
- Some of the methods proposed by researchers to remove ambiguity is preserving ambiguity, e.g. (Shemtov 1997; Emele & Dorna 1998; Knight & Langkilde 2000; Tong Gao et al. 2015, Umber & Bajwa 2011) [39, 46, 65, 125, 139].

Most higher-level NLP applications involve aspects that emulate intelligent behaviour and apparent comprehension of natural language. More broadly speaking, the technical operationalization of increasingly advanced aspects of cognitive natural language processing challenges behaviour represents one of the developmental trajectories of NLP (see trends among CoNLL shared tasks above). The Python programing language provides a wide range of tools and libraries for attacking specific NLP tasks.
To find the words which have a unique context and are more informative, noun phrases are considered in the text documents. Named entity recognition (NER) is a technique to recognize and separate the named entities and group them under predefined classes. But in the era of the Internet, where people use slang not the traditional or standard English which cannot be processed by standard natural language processing tools. Ritter (2011)  proposed the classification of named entities in tweets because standard NLP tools did not perform well on tweets.
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. A major drawback of statistical methods is that they require elaborate feature engineering. Since 2015, the statistical approach was replaced by the neural networks approach, using word embeddings to capture semantic properties of words. CRAG’s methodology is distinguished by its dynamic approach to document retrieval.
Using these approaches is better as classifier is learned from training data rather than making by hand. The naïve bayes is preferred because of its performance despite its simplicity (Lewis, 1998)  In Text Categorization two types of models have been used (McCallum and Nigam, 1998) . But in first model a document is generated by first choosing a subset of vocabulary and then using the selected words any number of times, at least once irrespective of order. It takes the information of which words are used in a document irrespective of number of words and order.
Artificial Intelligence (AI) has been used for processing data to make decisions, Interact with humans, and understand their feelings and emotions. With the advent of the Internet, people share and express their thoughts on day-to-day activities and global and local events through text messaging applications. Hence, it is essential for machines to understand emotions in opinions, feedback, and textual dialogues to provide emotionally aware responses to users in today’s online world. The field of text-based emotion detection (TBED) is advancing to provide automated solutions to various applications, such as business and finance, to name a few.
For example, CONSTRUE, it was developed for Reuters, that is used in classifying news stories (Hayes, 1992) . 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) . IE systems should work at many levels, from word recognition to discourse analysis at the level of the complete document. An application of the Blank Slate Language Processor (BSLP) (Bondale et al., 1999)  approach for the analysis of a real-life natural language corpus that consists of responses to open-ended questionnaires in the field of advertising.
The LSP-MLP helps enabling physicians to extract and summarize information of any signs or symptoms, drug dosage and response data with the aim of identifying possible side effects of any medicine while highlighting or flagging data items . The National Library of Medicine is developing The Specialist System [78,79,80, 82, 84]. It is expected to function as an Information Extraction tool for Biomedical Knowledge Bases, particularly Medline abstracts.
