For machine translation, we use a neural network architecture called Sequence-to-Sequence (Seq2Seq) (This architecture is the basis of the OpenNMT framework that we use at our company). Naive Bayes is a probabilistic classification algorithm used in NLP to classify texts, which assumes that all text features are independent of each other. Despite its simplicity, this algorithm has proven to be very effective in text classification due to its efficiency in handling large datasets. Long short-term memory (LSTM) – a specific type of neural network architecture, capable to train long-term dependencies. Frequently LSTM networks are used for solving Natural Language Processing tasks.

They help machines make sense of the data they get from written or spoken words and extract meaning from them. For estimating machine translation quality, we use machine learning algorithms based on the calculation of text similarity. One of the most noteworthy of these algorithms is the XLM-RoBERTa model based on the transformer architecture. NLP uses either rule-based or machine learning approaches to understand the structure and meaning of text. It plays a role in chatbots, voice assistants, text-based scanning programs, translation applications and enterprise software that aids in business operations, increases productivity and simplifies different processes.

  • The Machine and Deep Learning communities have been actively pursuing Natural Language Processing (NLP) through various techniques.
  • Each document is represented as a vector of words, where each word is represented by a feature vector consisting of its frequency and position in the document.
  • The basic idea of text summarization is to create an abridged version of the original document, but it must express only the main point of the original text.
  • Machine learning algorithms are mathematical and statistical methods that allow computer systems to learn autonomously and improve their ability to perform specific tasks.

It’s also used to determine whether two sentences should be considered similar enough for usages such as semantic search and question answering systems. Symbolic AI uses symbols to represent knowledge and relationships between concepts. It produces more accurate results by assigning meanings to words based on context and embedded knowledge to disambiguate language. It is a highly demanding NLP technique where the algorithm summarizes a text briefly and that too in a fluent manner.
