Natural Language Processing Meaning, Techniques, and Models

Chatbots were the earliest examples of virtual assistants prepared for solving customer queries and service requests. The first chatbot was created in 1966, thereby validating the extensive history of technological evolution of chatbots. The working mechanism in most of the NLP examples focuses on visualizing a sentence as a ‘bag-of-words’. NLP ignores the order of appearance of words in a sentence and only looks for the presence or absence of words in a sentence. The ‘bag-of-words’ algorithm involves encoding a sentence into numerical vectors suitable for sentiment analysis.

How Are Algorithms Used for Natural Language Processing?

Many languages carry different orders of sentence structuring and then translate them into the required information. The reviews and feedback can occur from social media platforms, contact forms, direct mailing, and others. To make things digitalize, Artificial intelligence has taken the momentum with greater human dependency on computing systems. The computing system can further communicate and perform tasks as per the requirements. Recall that CNNs were designed for images, so not surprisingly, they’re applied here in the context of processing an input image and identifying features from that image.

Artificial Intelligence (AI), including NLP, has changed significantly over the last five years after it came to the market. Therefore, by the end of 2024, NLP will have diverse methods to recognize and understand natural language. It has transformed from the traditional systems capable of imitation and statistical processing to the relatively recent neural networks like BERT and transformers. Natural Language Processing techniques nowadays are developing faster than they used to. NLP can also provide answers to basic product or service questions for first-tier customer support. “NLP in customer service tools can be used as a first point of engagement to answer basic questions about products and features, such as dimensions or product availability, and even recommend similar products.

Another kind of model is used to recognize and classify entities in documents. For each word in a document, the model predicts whether that word is part of an entity mention, and if so, what kind of entity is involved. For example, in “XYZ Corp shares traded for $28 yesterday”, “XYZ Corp” is a company entity, “$28” is a currency amount, and “yesterday” is a date. The training data for entity recognition is a collection of texts, where each word is labeled with the kinds of entities the word refers to. This kind of model, which produces a label for each word in the input, is called a sequence labeling model. As Christina Valente, a Senior Director of Product Operations explains, “before Akkio ML, projects took months-long engineering effort, costing hundreds of thousands of dollars.
