18 Natural Language Processing Examples to Know

Adding a Natural Language Interface to Your Application

For instance, simply representing the inclusion or exclusion of the words ‘stronger’ or ‘weaker’ is highly informative about the meaning of the instruction. MonkeyLearn is a machine learning platform that offers a wide range of text analysis tools for businesses and individuals. With MonkeyLearn, users can build, train, and deploy custom text analysis models to extract insights from their data. The platform provides pre-trained models for everyday text analysis tasks such as sentiment analysis, entity recognition, and keyword extraction, as well as the ability to create custom models tailored to specific needs. Natural language processing (NLP) is a field within artificial intelligence that enables computers to interpret and understand human language.

Deep neural networks include an input layer, at least three but usually hundreds of hidden layers, and an output layer, unlike neural networks used in classic machine learning models, which usually have only one or two hidden layers. Directly underneath AI, we have machine learning, which involves creating models by training an algorithm to make predictions or decisions based on data. It encompasses a broad range of techniques that enable computers to learn from and make inferences based on data without being explicitly programmed for specific tasks. The rise of ML in the 2000s saw enhanced NLP capabilities, as well as a shift from rule-based to ML-based approaches. Today, in the era of generative AI, NLP has reached an unprecedented level of public awareness with the popularity of large language models like ChatGPT.

Proven and tested hands-on strategies to tackle NLP tasks

Our supervised algorithms were relatively simple, and authors should consider incorporating other features into their training datasets. For example, we could have added columns to describe the sentiment of a review (based on the Bing lexicon), its lexical diversity, or its length in words or characters. When doing this, it is important to normalise the values of these features before algorithm training. Artificial neural networks are so-called because they share a conceptual topography with the human central nervous system. Each neuron sums its inputs, multiplies this by a weight, and transforms the signal through an activation function. The weight of each neuron and their collective arrangement will affect model performance [14].

We then divided these 1100 words’ instances into ten contiguous folds, with 110 unique words in each fold. As an illustration, the chosen instance of the word “monkey” can appear in only one of the ten folds. We used nine folds to align the brain embeddings derived from IFG with the 50-dimensional contextual embeddings derived from GPT-2 (Fig.1D, blue words).

Get Started with Natural Language Processing

The purpose of this article is to provide an introduction to the use of common machine learning techniques for analysing passages of written text. Levothyroxine and Viagra were reviewed with a higher proportion of positive sentiments than Oseltamivir and Apixaban. One of the three LDA clusters clearly represented drugs used to treat mental health problems. A common theme suggested by this cluster was drugs taking weeks or months to work. Supervised machine learning algorithms predicted positive or negative drug ratings with classification accuracies ranging from 0.664, 95% CI [0.608, 0.716] for the regularised regression to 0.720, 95% CI [0.664,0.776] for the SVM. NLG derives from the natural language processing method called large language modeling, which is trained to predict words from the words that came before it.

Being able to create a shorter summary of longer text can be extremely useful given the time we have available and the massive amount of data we deal with daily. The RNN (specifically, an encoder-decoder model) is commonly used given input text as a sequence (with the words encoded using a word embedding) feeding a bidirectional LSTM that includes a mechanism for attention (i.e., where to apply focus). ELECTRA, short for Efficiently Learning an Encoder that Classifies Token Replacements Accurately, is a recent method used to train and develop language models.

Use Case: Direct Response Marketing

Subsequent use of the Palm 2 language model made Bard more visual in its responses to user queries. Bard also incorporated Google Lens, letting users upload images in addition to written prompts. The Gemini language model was added later, enabling more advanced reasoning, planning and understanding. Unlike prior AI models from Google, Gemini is natively multimodal, meaning it’s trained end to end on data sets spanning multiple data types. That means Gemini can reason across a sequence of different input data types, including audio, images and text. For example, Gemini can understand handwritten notes, graphs and diagrams to solve complex problems.

• These models utilize advanced algorithms and neural networks, often employing architectures like Recurrent Neural Networks (RNNs) or Transformers, to understand the intricate structures of language.
• The zero-shot encoding analysis suggests that the common geometric patterns of contextual embeddings and brain embeddings in IFG is sufficient to predict the neural activation patterns for unseen words.
• We also acknowledge the National Institutes of Health for their support under award numbers DP1HD (to A.G., Z.Z., A.P., B.A., G.C., A.R., C.K., F.L., A.Fl., and U.H.) and R01MH (to S.A.N.).
• A fundamental human cognitive feat is to interpret linguistic instructions in order to perform novel tasks without explicit task experience.

This article will be all about processing and understanding text data with tutorials and hands-on examples. Other connectionist methods have also been applied, including recurrent neural networks (RNNs), ideal for sequential problems (like sentences). RNNs have been around for some time, but newer models, like the long–short-term memory (LSTM) model, are also widely used for text processing and generation. The Markov model is a mathematical method used in statistics and machine learning to model and analyze systems that are able to make random choices, such as language generation. Markov chains start with an initial state and then randomly generate subsequent states based on the prior one. The model learns about the current state and the previous state and then calculates the probability of moving to the next state based on the previous two.

Data risks

Natural language processing has the ability to interrogate the data with natural language text or voice. This is also called “language in.” Most consumers have probably interacted with NLP without realizing it. For instance, NLP is the core technology behind virtual assistants, such as the Oracle Digital Assistant (ODA), Siri, Cortana, or Alexa. When we ask questions of these virtual assistants, NLP is what enables them to not only understand the user’s request, but to also respond in natural language. NLP applies both to written text and speech, and can be applied to all human languages. Other examples of tools powered by NLP include web search, email spam filtering, automatic translation of text or speech, document summarization, sentiment analysis, and grammar/spell checking.

The field of NLP, like many other AI subfields, is commonly viewed as originating in the 1950s. One key development occurred in 1950 when computer scientist and mathematician Alan Turing first conceived the imitation game, later known as the Turing test. This early benchmark test used the ability to interpret and generate natural language in a humanlike way as a measure of machine intelligence — an emphasis on linguistics that represented a crucial foundation for the field of NLP. ML is a subfield of AI that focuses on training computer systems to make sense of and use data effectively. Computer systems use ML algorithms to learn from historical data sets by finding patterns and relationships in the data. One key characteristic of ML is the ability to help computers improve their performance over time without explicit programming, making it well-suited for task automation.

The researchers noted that, like any advanced technology, there must be frameworks and guidelines in place to make sure that NLP tools are working as intended. The authors further indicated that failing to account for biases in the development and deployment of an NLP model can negatively impact model outputs and perpetuate health disparities. Privacy is also a concern, as regulations dictating data use and privacy protections for these technologies have yet to be established.

By training models on vast datasets, businesses can generate high-quality articles, product descriptions, and creative pieces tailored to specific audiences. This is particularly useful for marketing campaigns and online platforms where engaging content is crucial. Called DeepHealthMiner, the tool analyzed millions of posts from theInspire health forum and yielded promising results. The deluge of unstructured data pouring into government agencies in both analog and digital form presents significant challenges for agency operations, rulemaking, policy analysis, and customer service. NLP can provide the tools needed to identify patterns and glean insights from all of this data, allowing government agencies to improve operations, identify potential risks, solve crimes, and improve public services. Ways in which NLP can help address important government issues are summarized in figure 4.

Like most other artificial intelligence, NLG still requires quite a bit of human intervention. We’re continuing to figure out all the ways natural language generation can be misused or biased in some way. And we’re finding that, a lot of the time, text produced by NLG can be flat-out wrong, which has a whole other set of implications.

• However, the base form in this case is known as the root word, but not the root stem.
• “We’ve seen performance drops in question-answering for Singapore English, for example, of up to 19 percent,” says Ziems.
• The zero-shot inference demonstrates that the electrode activity vectors predicted from the geometric embeddings closely correspond to the activity pattern for a given word in the electrode space.
• Its natural language processing is trained on 5 million clinical terms across major coding systems.

We are not suggesting that classical psycholinguistic grammatical notions should be disregarded. In this paper, we define symbolic models as interpretable models that blend symbolic elements (such as nouns, verbs, adjectives, adverbs, etc.) with hard-coded rule-based operations. On the other hand, deep language models are statistical models that learn language from real-world data, often without explicit prior knowledge about language structure.

Natural language processing, or NLP, is a field of AI that enables computers to understand language like humans do. Our eyes and ears are equivalent to the computer’s reading programs and microphones, our brain to the computer’s processing program. NLP programs lay the foundation for the AI-powered chatbots common today and work in tandem with many other AI technologies to power the modern enterprise.
