Exploring the opportunities and challenges of NLP models in higher education: is Chat GPT a blessing or a curse?

Poorly structured data can lead to inaccurate results and prevent the successful implementation of NLP. Seunghak et al. [158] designed a Memory-Augmented-Machine-Comprehension-Network (MAMCN) to handle dependencies faced in reading comprehension. The model achieved state-of-the-art performance on document-level using TriviaQA and QUASAR-T datasets, and paragraph-level using SQuAD datasets. Fan et al. [41] introduced a gradient-based neural architecture search algorithm that automatically finds architecture with better performance than a transformer, conventional NMT models. They tested their model on WMT14 (English-German Translation), IWSLT14 (German-English translation), and WMT18 (Finnish-to-English translation) and achieved 30.1, 36.1, and 26.4 BLEU points, which shows better performance than Transformer baselines.

Sometimes this becomes an issue of personal choice, as data scientists often differ as to what they deem is the right language – whether it is R, Golang, or Python – for perfect data mining results. How this presents itself in data mining challenges is when different business situations arise, such as when a company needs to scale and has to lean heavily on virtualized environments. Secondly, we approach the solution from the business angle as well, where marketing and development teams ensure that accurate data is collected as much as possible. For example, businesses must ensure that survey questions are more representative of the objective, and data entry points, such as in retail, have a method of validating the data, such as email addresses. This way, when we analyze sentiment through emotion mining, it will lead to more accurate results.

Natural Language Processing (NLP) Challenges

While linguistics is an initial approach toward extracting the data elements from a document, it doesn’t stop there. The semantic layer that will understand the relationship between data elements and its values and surroundings have to be machine-trained too to suggest a modular output in a given format. There are several methods today to help train a machine to understand the differences between the sentences.

Initially, the data chatbot will probably ask the question ‘how have revenues changed over the last three-quarters? But once it learns the semantic relations and inferences of the question, it will be able to automatically metadialog.com perform the filtering and formulation necessary to provide an intelligible answer, rather than simply showing you data. A third challenge of NLP is choosing and evaluating the right model for your problem.

Data quality and availability

Data labeling is easily the most time-consuming and labor-intensive part of any NLP project. Building in-house teams is an option, although it might be an expensive, burdensome drain on you and your resources. Employees might not appreciate you taking them away from their regular work, which can lead to reduced productivity and increased employee churn. While larger enterprises might be able to get away with creating in-house data-labeling teams, they’re notoriously difficult to manage and expensive to scale. Due to the sheer size of today’s datasets, you may need advanced programming languages, such as Python and R, to derive insights from those datasets at scale.

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. Chunking known as “Shadow Parsing” labels parts of sentences with syntactic correlated keywords like Noun Phrase (NP) and Verb Phrase (VP). Various researchers (Sha and Pereira, 2003; McDonald et al., 2005; Sun et al., 2008) [83, 122, 130] used CoNLL test data for chunking and used features composed of words, POS tags, and tags. NLP can also aid in identifying potential health risks and providing targeted interventions to prevent adverse outcomes. It can also be used to develop healthcare chatbot applications that provide patients with personalized health information, answer common questions, and triage symptoms.

What are the main challenges and risks of implementing NLP solutions in your industry?

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. Human language is symbolic (based on logic, rules, and ontologies), discrete and highly ambiguous. In the  example Tweet “ there is little awareness or understanding about feelings of grief and bereavement when a person is still living, but when you care for someone with dementia, loss does not just mean loss of life” (“twitter.com”, 2021). This demonstrates high variability, whereby the core message is  living grief and bereavement.

Pragmatic level focuses on the knowledge or content that comes from the outside the content of the document. Real-world knowledge is used to understand what is being talked about in the text. When a sentence is not specific and the context does not provide any specific information about that sentence, Pragmatic ambiguity arises (Walton, 1996) [143]. Pragmatic ambiguity occurs when different persons derive different interpretations of the text, depending on the context of the text. Semantic analysis focuses on literal meaning of the words, but pragmatic analysis focuses on the inferred meaning that the readers perceive based on their background knowledge. ” is interpreted to “Asking for the current time” in semantic analysis whereas in pragmatic analysis, the same sentence may refer to “expressing resentment to someone who missed the due time” in pragmatic analysis.

Bibliographic and Citation Tools

It is a plain text free of specific fonts, diagrams, or elements that make it difficult for machines to read a document line by line. Natural Language Generation is the process of generating human-like language from structured data. This technique is used in report generation, email automation, and chatbot responses. Text summarization is the process of generating a summary of a text document.

There is use of hidden Markov models (HMMs) to extract the relevant fields of research papers. These extracted text segments are used to allow searched over specific fields and to provide effective presentation of search results and to match references to papers. For example, noticing the pop-up ads on any websites showing the recent items you might have looked on an online store with discounts.

Search engines like Google even use NLP to better understand user intent rather than relying on keyword analysis alone. Although NLP became a widely adopted technology only recently, it has been an active area of study for more than 50 years. IBM first demonstrated the technology in 1954 when it used its IBM 701 mainframe to translate sentences from Russian into English.
