Natural language processing, which evolved from computational linguistics, uses methods from various disciplines such as computer science, artificial intelligence, linguistics, and data science to enable computers to understand human language in written and verbal form. While computational linguistics focuses more on aspects of language, natural language processing emphasizes the use of machine learning and deep learning techniques to perform tasks such as translation or answering questions. Natural language processing works by converting unstructured data into a structured data format. It does this by identifying named entities (a process called named entity recognition) and identifying word patterns using methods such as tokenization, stemming, and lemmatization, which examine the root shapes of words. For example, the suffix -ed on a word, such as called, indicates the past tense, but it has the same basic infinitive (call) as the verb in the present calling. NLG solutions, even basic ones, usually take a long time to set up. You will also have to pay for a solution and possibly the associated NLG services. You should take a realistic look at technology, what it can do for you, and how well you can grow with it. Early chatbot systems, including CleverBot, developed by Rollo Carpenter in 1988 and launched in 1997, answer questions by identifying how a human answered the same question in a conversational database via an information retrieval (IR) approach. Modern chatbot systems are primarily based on machine learning (ML) models, such as sequence-to-sequence learning and reinforcement learning in human speech output generation. Hybrid models have also been studied. For example, Alibaba Shopping Assistant uses an IR approach to extract the best candidates from the knowledge base before using the ML-driven seq2seq model to re-evaluate candidates and generate the response.
 Despite progress, there are still many challenges to produce automated creative and humorous content that rivals human production. In an experiment to generate satirical headlines, the results of their best BERT-based model were perceived as fun 9.4% of the time (while true onion headlines were 38.4%) and a GPT-2 model suitable for satirical headlines scored 6.9%.  It was pointed out that two main problems with humor generation systems are the lack of annotated datasets and the lack of formal evaluation methods that could be applicable to other creative content. Some argued that there is a lack of attention to the creative aspects of language production within NLG compared to other applications. NLG researchers benefit from insights into what constitutes creative language production, as well as structural features of storytelling that also have the potential to improve NLG results in data-to-text systems.  Content: Decide what information should be included in the text. For example, in the pollen example above, decide to explicitly mention that the pollen content in the southeast is 7. Natural language generation is another subset of natural language processing. While natural language understanding focuses on computer reading comprehension, natural language generation allows computers to write. NLG is the process of generating a text response in human language based on data entry. This text can also be converted to speech format using text-to-speech services. Do you produce these kinds of stories on a regular basis? If these stories are presented in a coherent and reproducible format (e.g.
Do you report or tell a story about the same types of numbers every week or month)? An example of interactive use of NLG is the WYSIWYM framework. It means What You See is What You Mean and allows users to view and edit the continuously rendered view (NLG output) of an underlying formal language document (NLG input), which manipulates the formal language without learning it. At the Marketing AI Institute, we`ve spent years studying AI technologies and their impact on marketing, including NLG. We`ve gathered our expertise in this article, which includes everything you need to know about this transformative AI technology. NLG also includes text summary functions that generate summaries from captured documents while maintaining the integrity of the information. Extractive Summary is the AI innovation behind the key point analysis used in That`s Defactable. Chatbots, voice assistants, and AI blog writers (to name a few) all use natural language generation. NLG systems can turn numbers into narratives based on predefined patterns.
You can predict which words should be generated next (for example, in an email that you actively type). Or the most sophisticated systems can formulate summaries, articles, or entire answers. Natural language generation (NLG) is the process of transforming data into natural language using artificial intelligence. Transformer. This neural network architecture is able to learn deep dependencies in language and create sentences from the meaning of words. Transformer is linked to AI. It was developed by OpenAI, a non-profit AI research company in San Francisco. Transformer includes two encoders: one to process inputs of any length and another to output generated sets. Initially, NLG systems used templates to generate text.
Based on certain data or queries, an NLG system would fill the void, like a Mad Libs game. But over time, natural language generation systems have evolved with the application of hidden Markov chains, recurrent neural networks, and transformers, enabling more dynamic real-time text generation. NLP translates what you say into data. An NLG system uses this data to generate speech. But what if the machine`s response doesn`t make sense? This is where natural language understanding (NLU) comes in. Structuring of documents: Global organization of the information to be transmitted. For example, the decision to describe areas with high pollen content first, rather than areas with low pollen content. NLG has been around since the development of ELIZA in the mid-1960s, but the methods were first used commercially in the 1990s.  NLG techniques range from simple model-based systems such as a mail merge that generates form letters to systems that have a complex understanding of human grammar. NLG can also be achieved by training a statistical model using machine learning, usually on a large corpus of human-written text.  NLG`s generation of creative language has been assumed since the beginning of the field. A new pioneer in this field is Phillip Parker, who has developed an arsenal of algorithms capable of automatically generating textbooks, crosswords, poems and books on topics ranging from binding to cataracts.
 The advent of large language models based on pre-trained transformers such as GPT-3 has also enabled breakthroughs, with these models showing a recognizable ability to create and write tasks.  NLG is related to both NLU and Information Retrieval. It is also associated with text summary, speech generation, and machine translation. Much of the fundamental research in NLG also overlaps with computational linguistics and fields dealing with human-computer and machine-to-human interaction. NLG research often focuses on creating computer programs that provide context to data points. Advanced NLG software can evaluate large amounts of digital data, identify patterns, and share that information in a way that is easy for humans to understand. The speed of NLG software is particularly useful for producing time-sensitive news and other stories on the Internet. In the best case, NLG output can be published verbatim as web content. Natural language generation (NLG) is a software process that generates natural language output.
In one of the most frequently cited surveys of NLG methods, NLG is characterized as « the branch of artificial intelligence and computational linguistics that deals with the construction of computer systems capable of producing intelligible texts in English or other human languages from an underlying non-linguistic representation of information. »  Natural language processing is the process of accurately translating what you say into machine-readable data so that NLG can use that data to generate a response. NLP is an umbrella term that refers to the use of computers to understand human language in written and verbal form. NLP is based on a framework of rules and components and converts unstructured data into a structured data format. The process of generating text can be as simple as keeping a ready-made list of text that is copied and pasted, possibly linked to adhesive text. The results can be satisfactory in simple areas such as horoscope machines or custom business letter generators. However, a sophisticated NLG system must include planning and merging phases of information to enable the generation of text that looks natural and does not repeat. Typical phases of natural language generation, suggested by Dale and Reiter, are as follows: A captioning system consists of two subtasks. In image analysis, the characteristics and attributes of an image are recognized and labeled before these outputs are assigned to linguistic structures. Recent research uses deep learning approaches through functions of a pre-trained convolutional neural network such as AlexNet, VGG or Caffe, where subtitle generators use a pre-trained network activation layer as input functions. Text generation, the second task, is performed using a variety of techniques. In the Midge system, for example, input images are displayed as triplets consisting of object/offer identifiers, action/pose recognitions, and spatial relationships.
