Entity extraction uses an application of NLP called Named Entity Recognition. It allows a user to extract relevant and valuable information from a data set. This application of NLP can be a crucial player during research or query resolution where a user is searching for a particular fact or answer. This NLP use case is also about making the most out of vast information to derive concrete insights. For example, NLP can understand the drug’s formation and compound to understand how a medicine would react to a particular patient and disease. NLP in healthcare facilities makes the information more accessible and understandable.
The encoder takes the input sentence that must be translated and converts it into an abstract vector. The decoder converts this vector into a sentence in a target language. The attention mechanism in between two neural networks allowed the system to identify the most important parts of the sentence and devote most of the computational power to it. This allowed data scientists to effectively handle long input sentences.
A new and interesting use case of NLP in cybersecurity is data exfiltration prevention. Data exfiltration is a breach that involves unauthorized data copying through malware that is launched through specific domains. This expression means the activity to search and compare information like transportation rates, fuel rates, and other benchmark rates that are necessary to compare costs and identify cost-saving opportunities. Other NLP use cases in healthcare include handling PHI and cross-referencing symptoms. This article was drafted by former AIMultiple industry analyst Alamira Jouman Hajjar.

It then adds, removes, or replaces letters from the word, and matches it to a word candidate which fits the overall meaning of a sentence. Is primarily used for risk management and alpha generation in the finance world. Institutions like the Bank of America and JP Morgan Chase rely on this technology.
AI solutions can do personalized offers.AI solutions can collect client’s feedback while servicing them. This type of analysis in the finance industry uses solutions based on NLP to find financial news, and emotional, and factual reactions to it. Further, they can forecast the market reaction to particular financial news in this environment. To make machines grasp people’s language, developers train algorithms.
These companies all use AI chatbots with NLP to understand, address and solve daily human requests of assistance. Relevant data can be also extracted and directly put into accounting documentation by saving further time, and money . The NLP application can give a hand by reading, classifying, labelling, and filing this huge amount of document, with consequent streamlining of the whole supply process. Cross-referencing symptoms habilitates more precise diagnosis and accurate patient monitoring through assigning an appropriate code to each patient. These data can be also read by NLP with timesaving and better accuracy in treatment administration.
Interpreting voice inputs, understanding speech, or analyzing written or textual information are several examples of natural language processing. One of the novel findings in this field was developed at Cornell University. FinBert offers financial sentiment analysis with pre-trained models. The authors suggest that pre-trained language models do not need many labeled examples.
For instance, it handles human speech input for such voice assistants as Alexa to successfully recognize a speaker’s intent. Here, text is classified based on an author’s feelings, judgments, and opinion. Sentiment analysis helps brands learn what the audience or employees think of their company or product, prioritize customer service tasks, and detect industry trends. The market is almost saturated with speech recognition technologies, but a few startups are disrupting the space with deep learning algorithms in mining applications, uncovering more extensive possibilities. The NLP technologies bring out relevant data from speech recognition equipment which will considerably modify analytical data used to run VBC and PHM efforts.
Automated speech/voice recognition
When we feed machines input data, we represent it numerically, because that’s how computers read data. This representation must contain not only the word’s meaning, but also its context and semantic connections to other words. To densely pack this amount of data in one representation, we’ve started using vectors, or word embeddings. By capturing relationships between words, the models have increased accuracy and better predictions. Deep learning or deep neural networks is a branch of machine learning that simulates the way human brains work.
In this case, NLP is used for the initial scraping of CVs according to set criteria. During the interview, the CI determines whether the candidate is compliant with the position or not. The CN streamlines the sale funnel and presents viable options based on user history and expressed preferences. Instead of relying on strict commands, development of natural language processing machines are learning to interact with people on people’s terms. As a result, you get a lot of information gathered with less effort and more time to go deep into insights. For instance, a couple of algorithms can save many hours of manual work and make it easy for the non-tech specialist to handle data on their own.

The exact functioning of different chatbots might be different, but all follow a database or algorithm in which, when the user input is passed, a response is given which solves a business problem. In the process of Text analytics, the source text or documents are processed, then various NLP methods are applied to them. If the text happens to be web-scraped, there will be a lot of HTML, which has to be cleaned. Text Analytics is the process of gathering useful data and insights from text data.

By applying NLP and big data, companies can create patterns of how clients spend their money. With this information, they can forecast the volume of funds that flows out per day or per month. NLP with other models can offer a different approach to solve this task. It is worthwhile mentioning that AI auditing solutions cannot substitute auditor jobs. But they can rather upskill these jobs and raise the quality of the audit.
Natural Language Processing Applications and Use Cases
As there is so much textual information in the finance sector, financial entities resort to software based on natural language processing to better process it. Considered an advanced version of NLTK, spaCy is designed to be used in real-life production environments, operating with deep learning frameworks like TensorFlow and PyTorch. SpaCy is opinionated, meaning that it doesn’t give you a choice of what algorithm to use for what task — that’s why it’s a bad option for teaching and research. Instead, it provides a lot of business-oriented services and an end-to-end production pipeline. This technique inspired by human cognition helps enhance the most important parts of the sentence to devote more computing power to it. Originally designed for machine translation tasks, the attention mechanism worked as an interface between two neural networks, an encoder and decoder.
Natural Language Processing is a type of AI that seeks to enable computers to process or understand human language. Ideally, NLP does this by programming computers to analyze and process large quantities of natural language data. It can manipulate speech and text through computational power enabled by various software. For a more in depth look at deep learning, machine learning, and artificial intelligence refer to this article.
This is possible with specific NLP software that extracts the subjective meaning of thousands and thousands of comments, pieces of advice, emoticons, and posts that are published on social media every second. Semantic search refers to a search method that aims to not only find keywords but understand the context of the search query and suggest fitting responses. Retailers claim that on average, e-commerce sites with a semantic search bar experience a mere 2% cart abandonment rate, compared to the 40% rate on sites with non-semantic search. Several retail shops use NLP-based virtual assistants in their stores to guide customers in their shopping journey. A virtual assistant can be in the form of a mobile application which the customer uses to navigate the store or a touch screen in the store which can communicate with customers via voice or text.
Intent Analysis – can be used to analyze specific phrases and determine the intentions behind them. For example, it can be used to determine whether a customer is going to buy something, or if he still considering different options. For a personalized demo using your company’s keywords, don’t hesitate to reach us. For example, financial institutions can find all mentions of some policy, regulation, or event with their financial impact as a context. In this case, the system will generate all mentions of the query phrase and highlight the mentions with financial impact. There are different views on what’s considered high quality data in different areas of application.

A set of researchers from France worked on developing another NLP based algorithm that would monitor, detect and prevent hospital-acquired infections among patients. NLP helped in rendering unstructured data which was then used to identify early signs and intimate clinicians accordingly. Healthcare organizations can use NLP to transform the way they deliver care and manage solutions. Organizations can use machine learning in healthcare to improve provider workflows and patient outcomes.
It relies on the data that it catalogs based on what the other millions of Google users are searching for when inputting search terms. This is possible by using natural language processing that helps understand subtleties between various search terms. NLP is a component of AI that utilizes machine learning algorithms to empower computer systems to comprehend and interpret human language. NLP is most commonly linked with initiatives to improve human-to-machine interactions, such as a customer support chatbot or a virtual assistant. At Gramener, we help global pharmaceutical leaders decode unstructured text such as patient information and clinical trial data using natural language processing techniques.

Deep learning propelled NLP onto an entirely new plane of technology. For example, grammar already consists of a set of rules, same about spellings. A system armed with a dictionary will do its job well, though it won’t be able to recommend a better choice of words and phrasing. Some common applications of text classification include the following.
For instance, Haptik produced a virtual assistant for Tata Mutual Fund to enhance customer retention and reduce call center workload. Initiative augmented the workforce of Tata by allowing employees to focus solely on urgent customer issues, by cutting call center enquiries by approximately 70%.

In NLP, one quality parameter is especially important — representational. There are statistical techniques for identifying sample size for all types of research. For example, considering the number of features (x% more examples than number of features), model parameters , or number of classes. Use your own knowledge or invite domain experts to correctly identify how much data is needed to capture the complexity of the task. The curse of dimensionality, when the volumes of data needed grow exponentially with the dimension of the model, thus creating data sparsity.
