Challenges and solutions to employing natural language processing and machine learning to measure patients health literacy and physician writing complexity: The ECLIPPSE study PMC

A systematic review of applications of natural language processing and future challenges with special emphasis in text-based emotion detection Artificial Intelligence Review

The pipeline integrates modules for basic NLP processing as well as more advanced tasks such as cross-lingual named entity linking, semantic role labeling and time normalization. Thus, the cross-lingual framework allows for the interpretation of events, participants, locations, and time, as well as the relations between them. Output of these individual pipelines is intended to be used as input for a system that obtains event centric knowledge graphs. All modules take standard input, to do some annotation, and produce standard output which in turn becomes the input for the next module pipelines. Their pipelines are built as a data centric architecture so that modules can be adapted and replaced. Furthermore, modular architecture allows for different configurations and for dynamic distribution.

Nowadays NLP is in the talks because of various applications and recent developments although in the late 1940s the term wasn’t even in existence. 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.

While Natural Language Processing has its limitations, it still offers huge and wide-ranging benefits to any business. And with new techniques and new technology cropping up every day, many of these barriers will be broken through in the coming years. Since BERT considers up to 512 tokens, this is the reason if there is a long text sequence that must be divided into multiple short text sequences of 512 tokens.

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. Natural Language Understanding or Linguistics and Natural Language Generation which evolves the task to understand and generate the text. 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.

Title:Robust Natural Language Processing: Recent Advances, Challenges, and Future Directions

The Pilot earpiece will be available from September but can be pre-ordered now for $249. The earpieces can also be used for streaming music, answering voice calls, and getting audio notifications. SaaS natural language processing challenges text analysis platforms, like MonkeyLearn, allow users to train their own machine learning NLP models, often in just a few steps, which can greatly ease many of the NLP processing limitations above.

This necessitated that all storage and analysis of the data take place on a secure server behind the KPNC firewall. While the secure server represented a solution to the challenge of maintaining security on confiden tial information, the processes for receiving training and obtaining access to the secure server were understandably rigorous and time-consuming. Furthermore, occasional server connectivity problems and limitations on computational speed of analyses performed via the server portal, together created occasional delays in data processing for the non-KPNC investigators on the team. Another issue was that patient or physician names and phone numbers necessitated additional data security measures be taken.

Challenges

The ambiguity can be solved by various methods such as Minimizing Ambiguity, Preserving Ambiguity, Interactive Disambiguation and Weighting Ambiguity [125]. 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]. They cover a wide range of ambiguities and there is a statistical element implicit in their approach.

Eight ECLIPPSE investigators were subsequently asked by WB to participate in communications regarding challenges and solutions. Of these eight, five were then invited by WB to participate in a virtual, online focus group that lasted for 90 min. The purpose of the focus group was to mitigate regal bias by allowing researchers to act as sounding boards and identify those challenges and solutions that were shared between and within disciplines and teams. Participants were asked about challenges and solutions specific to the tasks that they had to perform, or to clarify who was knowledgeable about challenges and solutions they had less involvement in. Participants were presented with a preliminary table of challenges and solutions related to both the LP and the CP – based on the review of the study documents and the first set of interviews – to stimulate recall and generate rich discussion and promote consensus-building.

They all use machine learning algorithms and Natural Language Processing (NLP) to process, “understand”, and respond to human language, both written and spoken. Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature

Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for

future research directions and describes possible research applications.

In this article, we will learn about the evolution of NLP and how it became the way it is as today. After that, we will go into the advancement of neural networks and their applications in the field of NLP, especially the Recurrent Neural Network (RNN). In the end, we will go into the SOTA models such as Hierarchical Attention Network (HAN) and Bidirectional Encoder Representations from Transformers (BERT). In this paper, we provide a short overview of NLP, then we dive into the different challenges that are facing it, finally, we conclude by presenting recent trends and future research directions that are speculated by the research community. So, for building NLP systems, it’s important to include all of a word’s possible meanings and all possible synonyms.

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 [114]. The National Library of Medicine is developing The Specialist System [78–80, 82, 84]. It is expected to function as an Information Extraction tool for Biomedical Knowledge Bases, particularly Medline abstracts.

Earlier machine learning techniques such as Naïve Bayes, HMM etc. were majorly used for NLP but by the end of 2010, neural networks transformed and enhanced NLP tasks by learning multilevel features. Major use of neural networks in NLP is observed for word embedding where words are represented in the form of vectors. Initially focus was on feedforward [49] and CNN (convolutional neural network) architecture [69] but later researchers adopted recurrent neural networks to capture the context of a word with respect to surrounding words of a sentence. LSTM (Long Short-Term Memory), a variant of RNN, is used in various tasks such as word prediction, and sentence topic prediction.

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. 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?

This process, essential for tasks like machine translation and content summarization, requires substantial computational resources, making it less feasible for real-time applications or on devices with limited processing capabilities. This talk presents challenges and opportunities for Natural Language Processing (NLP) Applications, focusing on the future of NLP in the age of Large Language Models (LLMs). Representative examples of ChatGPT output are provided to illustrate areas where more exploration is needed, particularly with respect to task-specific goals. The goal of NLP is to accommodate one or more specialties of an algorithm or system. The metric of NLP assess on an algorithmic system allows for the integration of language understanding and language generation. Rospocher et al. [112] purposed a novel modular system for cross-lingual event extraction for English, Dutch, and Italian Texts by using different pipelines for different languages.

The innovative LLM-to-SLM method enhances the efficiency of SLMs by leveraging the detailed prompt representations encoded by LLMs. This process begins with the LLM encoding the prompt into a comprehensive representation. A projector then adapts this representation to the SLM’s embedding space, allowing the SLM to generate responses autoregressively. To ensure seamless integration, the method replaces or adds LLM representations into SLM embeddings, prioritizing early-stage conditioning to maintain simplicity. It aligns sequence lengths using the LLM’s tokenizer, ensuring the SLM can interpret the prompt accurately, thus marrying the depth of LLMs with the agility of SLMs for efficient decoding. Vendors offering most or even some of these features can be considered for designing your NLP models.

Many companies have more data than they know what to do with, making it challenging to obtain meaningful insights. As a result, many businesses now look to NLP and text analytics to help them turn their unstructured data into insights. Core NLP features, such as named entity extraction, give users the power to identify key elements like names, dates, currency values, and even phone numbers in text. Expert.ai’s NLP platform gives publishers and content producers the power to automate important categorization and metadata information through the use of tagging, creating a more engaging and personalized experience for readers.

Similarly, the researchers of this study were asked to provide a retrospective account of their experience with certain challenges, and their solutions for attempting to resolve those challenges. As with any qualitative study that involves a retrospective account, there is a possibility of recall bias. Relatedly, the coding of the challenges and solutions into broader categories reflects how the two raters interpreted the materials provided based on their unique perspectives. However, we attempted to reduce any variation by employing a consensus process between the two coders, and also by providing opportunities for the entire research team to comment and suggest revisions to our codes and categories within each domain in an ongoing fashion. Ambiguity is one of the major problems of natural language which occurs when one sentence can lead to different interpretations.

Customers can interact with Eno asking questions about their savings and others using a text interface. This provides a different platform than other brands that launch chatbots like Facebook Messenger and Skype. They believed that Facebook has too much access to private information of a person, which could get them into trouble with privacy laws U.S. financial institutions work under. Like Facebook Page admin can access full transcripts of the bot’s conversations. If that would be the case then the admins could easily view the personal banking information of customers with is not correct. It has been observed recently that deep learning can enhance the performances in the first four tasks and becomes the state-of-the-art technology for the tasks (e.g. [1–8]).

We also elected to retain these automated texts for subsequent linguistic analyses because such text was representative of some of the language used by physicians when messaging patients. Since the number of labels in most classification problems is fixed, it is easy to determine the score for each class and, as a result, the loss from the ground truth. In image generation problems, the output resolution and ground truth are both fixed. But in NLP, though output format is predetermined in the case of NLP, dimensions cannot be specified.

Balancing development of methods that were optimized using available data versus developing methods that were easily adaptable to a wider range of settings, i.e., transportability, also posed a challenge. This was especially important when trying to manage and come to consensus on research and publication priorities. After WB and DS introduced the idea for this study at a bi-weekly team meeting, each member of the team agreed to contribute to a comprehensive review of the methodologic process related to the ECLIPPSE project.

Among all the NLP problems, progress in machine translation is particularly remarkable. Neural machine translation, i.e. machine translation using deep learning, has significantly outperformed traditional statistical machine translation. The state-of-the art neural translation systems employ sequence-to-sequence learning models comprising RNNs [4–6]. End-to-end training and representation learning are the key features of deep learning that make it a powerful tool for natural language processing. It might not be sufficient for inference and decision making, which are essential for complex problems like multi-turn dialogue.

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 National Library of Medicine is developing The Specialist System [78,79,80, 82, 84]. Deep learning is also employed in generation-based natural language dialogue, in which, given an utterance, the system automatically generates a response and the model is trained in sequence-to-sequence learning [7]. Table 2 shows the performances of example problems in which deep learning has surpassed traditional approaches.

Deep learning refers to machine learning technologies for learning and utilizing ‘deep’ artificial neural networks, such as deep neural networks (DNN), convolutional neural networks (CNN) and recurrent neural networks (RNN). Recently, deep learning has been successfully applied to natural language processing and significant progress has been made. This paper summarizes the recent advancement of deep learning for natural language processing and discusses its advantages and challenges. Expected challenges, such as missing linguistic structural markers or the existence of text noise (e.g., clinician signatures, hyperlinks, etc.), were mostly a part of the data mining process, but nonetheless required creative solutions. Those challenges that were more unique to the process of assessing patient HL and physician linguistic complexity arose in the analysis phase (e.g., threshold decisions, rater selection, and training, etc.). Researchers in this field may find the articulation and resolution of these challenges to be particularly helpful, providing opportunities to act preemptively.

Those interested in engaging in interdisciplinary work in this field may also benefit from our explication of the challenges related to such collaboration and the processes we applied to facilitate and optimize our interdisciplinary research. Rationalist approach or symbolic approach assumes that a crucial part of the knowledge in the human mind is not derived by the senses but is firm in advance, probably by genetic inheritance. It was believed that machines can be made to function like the human brain by giving some fundamental knowledge and reasoning mechanism linguistics knowledge is directly encoded in rule or other forms of representation.

Low-resource languages

This was so prevalent that many questioned if it would ever be possible to accurately translate text. Even the business sector is realizing the benefits of this technology, with 35% of companies using NLP for email or text classification purposes. Additionally, strong email filtering in the workplace can significantly reduce the risk of someone clicking and opening a malicious email, thereby limiting the exposure of sensitive data. One of the first ideas in the field of NLP could be as early as in the 17th century.

How to combine symbol data and vector data and how to leverage the strengths of both data types remain an open question for natural language processing. Recently, Natural Language Processing (NLP) has witnessed pivotal advancements evolving various fields and transforming how we communicate and interact with computers by understanding human languages and dialects. However, many challenges still need to be addressed or improved to improve user performance. For example, mining software repositories have many open challenges, i.e., developing efficient techniques to handle and process massive research datasets, including source code, commit history, and bug reports. Similarly, researchers must develop state-of-the-art approaches to improve the performance of existing supervised and unsupervised learning approaches in classifying, clustering, and summarizing various social-media-based problems.

You can foun additiona information about ai customer service and artificial intelligence and NLP. A chatbot system uses AI technology to engage with a user in natural language—the way a person would communicate if speaking or writing—via messaging applications, websites or mobile apps. The goal of a chatbot is to provide users with the information they need, when they need it, while reducing the need for live, human intervention. This form of confusion or ambiguity is quite common if you rely on non-credible NLP solutions.

Overload of information is the real thing in this digital age, and already our reach and access to knowledge and information exceeds our capacity to understand it. This trend is not slowing down, so an ability to summarize the data while keeping the meaning intact is highly required. 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.

Agreeing on a set of research goals, terminology, and selection of collaboration tools that are available to all team members should be determined and agreed upon from the outset. In considering how to assess performance of both LP and CP, we faced a critical challenge due to the absence of true “gold standards” for either patient HL or physician linguistic complexity. While we did have self-reported HL as one previously validated “gold standard” for the development of the patient LP [43], it is a subjective measure that is more aligned with the construct of “HL-related self-efficacy ” and is therefore somewhat limited.

Text Analysis with Machine Learning

Today, employees and customers alike expect the same ease of finding what they need, when they need it from any search bar, and this includes within the enterprise. Join our 38k+ ML SubReddit, 41k+ Facebook Community, Discord Channel, and LinkedIn Group. The College of Engineering is training the next generation of engineers who will make a difference.

First, the capability of interacting with an AI using human language—the way we would naturally speak or write—isn’t new. And while applications like ChatGPT are built for interaction and text generation, their very nature as an LLM-based app imposes some serious limitations in their ability to ensure accurate, sourced information. Where a search engine returns results that are sourced and verifiable, ChatGPT does not cite sources and may even return information that is made up—i.e., hallucinations. However, if we need machines to help us out across the day, they need to understand and respond to the human-type of parlance. Natural Language Processing makes it easy by breaking down the human language into machine-understandable bits, used to train models to perfection. Yet, in some cases, words (precisely deciphered) can determine the entire course of action relevant to highly intelligent machines and models.

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 without any order. 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. There are particular words in the document that refer to specific entities or real-world objects like location, people, organizations etc. 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.

However, new techniques, like multilingual transformers (using Google’s BERT “Bidirectional Encoder Representations from Transformers”) and multilingual sentence embeddings aim to identify and leverage universal similarities that exist between languages. Ambiguity in NLP refers to sentences and phrases that potentially have two or more possible interpretations. To address these possible imprecisions during LP and CP model development, we ran testing and training sets and used cross validation to try and maintain generalizability across the entire sample population (see below). Next, to address the problem of the parser stoppages, periodic human oversight of data processing was necessary. When parser stoppages occurred, the location of the stoppage was excised, and the parser was run again.

• This form of confusion or ambiguity is quite common if you rely on non-credible NLP solutions.
• HMM may be used for a variety of NLP applications, including word prediction, sentence production, quality assurance, and intrusion detection systems [133].
• Harnessing written content from the patient portal to address HL and make progress in lowering HL demands of healthcare delivery systems is a novel approach.
• Despite simple tools like Flesch – Kincaid readability level [38], there currently are no high-throughput, theory-driven tools with sufficient validity to assess writing complexity using samples of physicians’ written communications with their patients [5].
• In our research, we rely on primary data from applicable legislation and secondary public domain data sources providing related information from case studies.

Trained to the specific language and needs of your business, MonkeyLearn’s no-code tools offer huge NLP benefits to streamline customer service processes, find out what customers are saying about your brand on social media, and close the customer feedback loop. Santoro et al. [118] introduced a rational recurrent neural network with the capacity to learn on classifying the information and perform complex reasoning based on the interactions between compartmentalized information. Finally, the model was tested for language modeling on three different datasets (GigaWord, Project Gutenberg, and WikiText-103). Further, they mapped the performance of their model to traditional approaches for dealing with relational reasoning on compartmentalized information. Since simple tokens may not represent the actual meaning of the text, it is advisable to use phrases such as “North Africa” as a single word instead of ‘North’ and ‘Africa’ separate words.

• Their model revealed the state-of-the-art performance on biomedical question answers, and the model outperformed the state-of-the-art methods in domains.
• The National Library of Medicine is developing The Specialist System [78–80, 82, 84].
• Descartes and Leibniz came up with a dictionary created by universal numerical codes used to translate text between different languages.
• This helps search systems understand the intent of users searching for information and ensures that the information being searched for is delivered in response.

[47] In order to observe the word arrangement in forward and backward direction, bi-directional LSTM is explored by researchers [59]. 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. One of the most interesting aspects of NLP is that it adds up to the knowledge of human language.

Bi-directional Encoder Representations from Transformers (BERT) is a pre-trained model with unlabeled text available on BookCorpus and English Wikipedia. This can be fine-tuned to capture context for various NLP tasks such as question answering, sentiment analysis, text classification, sentence embedding, interpreting ambiguity in the text etc. [25, 33, 90, 148]. Earlier language-based models examine the text in either of one direction which is used for sentence generation by predicting the next word whereas the BERT model examines the text in both directions simultaneously for better language understanding. BERT provides contextual embedding for each word present in the text unlike context-free models (word2vec and GloVe).
