- https://en.wikipedia.org/wiki/Islands_of_automation - was a popular term used largely during the 1980s to describe how rapidly developing automation systems were at first unable to communicate easily with each other. Industrial communication protocols, network technologies, and system integration helped to improve this situation. Just a few of the many examples of helping technologies are Modbus, Fieldbus, Ethernet, etc. It is more recently used by automation specialists to describe a discrete and fully enclosed automated system applied in a largely manual environment. In today's interconnected world it is uncommon for automated systems to be fully stand alone. Therefore, the old usage is defunct and the new usage is more appropriate for companies that wish to automate in a limited fashion.
- https://en.wikipedia.org/wiki/X10_(industry_standard) - a protocol for communication among electronic devices used for home automation (domotics). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio based protocol transport is also defined. X10 was developed in 1975 by Pico Electronics of Glenrothes, Scotland, in order to allow remote control of home devices and appliances. It was the first general purpose domotic network technology and remains the most widely available. Although a number of higher bandwidth alternatives exist, X10 remains popular in the home environment with millions of units in use worldwide, and inexpensive availability of new components.
- https://en.wikipedia.org/wiki/xPL_Protocol - an open protocol intended to permit the control and monitoring of home automation devices. The primary design goal of xPL is to provide a rich set of features and functionality, whilst maintaining an elegant, uncomplicated message structure. The protocol includes complete discovery and auto-configuration capabilities which support a fully "plug-n-play" architecture - essential to ensure a good end-user experience. xPL benefits from a strongly specified message structure, required to ensure that xPL-enabled devices from different vendors are able to communicate without the risk of incompatibilities. Communications between xPL applications on a Local Area Network (LAN) use UDP on port 3865. xPL development has primarily occurred in the DIY community, where users have written connecting software to existing protocols and devices. Some examples include bridges to other home automation protocols like Z-Wave and UPB. Commercially, the Logitech SqueezeCenter software for the Squeezebox supports xPL.

- https://en.wikipedia.org/wiki/Natural_language_processing - a subfield of linguistics, computer science, information engineering, and artificial intelligence concerned with the interactions between computers and human (natural) languages, in particular how to program computers to process and analyze large amounts of natural language data.Challenges in natural language processing frequently involve speech recognition, natural language understanding, and natural language generation.
- https://en.wikipedia.org/wiki/History_of_natural_language_processing - describes the advances of natural language processing (Outline of natural language processing). There is some overlap with the history of machine translation, the history of speech recognition, and the history of artificial intelligence.
- https://en.wikipedia.org/wiki/Natural-language_understanding - or natural-language interpretation (NLI) is a subtopic of natural-language processing in artificial intelligence that deals with machine reading comprehension. Natural-language understanding is considered an AI-hard problem. There is considerable commercial interest in the field because of its application to automated reasoning, machine translation, question answering, news-gathering, text categorization, voice-activation, archiving, and large-scale content analysis.
- https://en.wikipedia.org/wiki/Natural-language_generation - a software process that transforms structured data into natural language. It can be used to produce long form content for organizations to automate custom reports, as well as produce custom content for a web or mobile application. It can also be used to generate short blurbs of text in interactive conversations (a chatbot) which might even be read out by a text-to-speech system.Automated NLG can be compared to the process humans use when they turn ideas into writing or speech. Psycholinguists prefer the term language production for this process, which can also be described in mathematical terms, or modeled in a computer for psychological research. NLG systems can also be compared to translators of artificial computer languages, such as decompilers or transpilers, which also produce human-readable code generated from an intermediate representation. Human languages tend to be considerably more complex and allow for much more ambiguity and variety of expression than programming languages, which makes NLG more challenging.

- Tutorial: Computational modelling of metaphor | EACL 2014 - Metaphor processing is a rapidly growing area in NLP. The ubiquity of metaphor in language has been established in a number of corpus studies and the role it plays in human reasoning has been confirmed in psychological experiments. This makes metaphor an important research area for computational and cognitive linguistics, and its automatic identification and interpretation indispensable for any semanticsoriented NLP application. The tutorial is targeted both at NLP researchers who are new to metaphor and need a comprehensive overview of metaphor processing techniques and applications, as well as at scientists working in the field who want to stay up to date on the recent advances in metaphor research.
- languagengine - Blog - What Happened to Old School NLP? - For the last 25 or so years, NLP has consisted almost entirely of fairly simple statistical models of language have prevailed. Rather than using carefully built grammars and fancy parsers, rather than trying to build systems that rely on linguistics, instead modern NLP tries to learn as much as possible from scratch. NLP research is now, essentially, just a branch of machine learning rather than a branch of linguistics. What happened? 
- -1803.11175- Universal Sentence Encoder - We present models for encoding sentences into embedding vectors that specifically target transfer learning to other NLP tasks. The models are efficient and result in accurate performance on diverse transfer tasks. Two variants of the encoding models allow for trade-offs between accuracy and compute resources. For both variants, we investigate and report the relationship between model complexity, resource consumption, the availability of transfer task training data, and task performance. Comparisons are made with baselines that use word level transfer learning via pretrained word embeddings as well as baselines do not use any transfer learning. We find that transfer learning using sentence embeddings tends to outperform word level transfer. With transfer learning via sentence embeddings, we observe surprisingly good performance with minimal amounts of supervised training data for a transfer task. We obtain encouraging results on Word Embedding Association Tests (WEAT) targeted at detecting model bias. Our pre-trained sentence encoding models are made freely available for download and on TF Hub.

- Metacat - a computer model of analogy-making and perception that builds on the foundations of an earlier model called Copycat. Copycat was originally developed by Douglas Hofstadter and Melanie Mitchell as part of a research program aimed at computationally modeling the fundamental mechanisms underlying human thought processes. Central to the philosophy of this research is the belief that the mind's ability to perceive connections between apparently dissimilar things, and to make analogies based on these connections, lies at the heart of intelligence. According to this view, to understand the analogical mechanisms of thinking and perception is to understand the source of the remarkable fluidity of the human mind, including its hidden wellsprings of creativity.
Like Copycat, Metacat operates in an idealized world of analogy problems involving short strings of letters. Although the program understands only a limited set of concepts about its letter-string world, its emergent processing mechanisms give it considerable flexibility in recognizing and applying these concepts in a wide variety of situations. The program's high-level behavior emerges in a bottom-up manner from the collective actions of many small nondeterministic processing agents (called codelets) working in parallel, in much the same way that an ant colony's high-level behavior emerges from the individual behaviors of the underlying ants, without any central executive directing the course of events.
Metacat focuses on the issue of self-watching: the ability of a system to perceive and respond to patterns that arise not only in its immediate perceptions of the world, but also in its own processing of those perceptions. Copycat lacked such an "introspective" capacity, and consequently lacked insight into how it arrived at its answers. It was unable to notice similarities between analogies, or to explain the differences between them or why one might be considered to be better or worse than another. In contrast, Metacat's self-watching mechanisms enable it to create much richer representations of analogies, allowing it to compare and contrast answers in an insightful way. Furthermore, it is able to recognize, remember, and recall patterns that occur in its own "train of thought" as it makes analogies. For instance, by monitoring its own processing, Metacat can often recognize when it has fallen into a repetitive cycle of behavior, enabling it to break out of its "rut" and try something else. 
- https://en.wikipedia.org/wiki/Virtual_assistant - a software agent that can perform a range of tasks or services for a user based on user input such as commands or questions, including verbal ones. Such technologies often incorporate chatbot capabilities to simulate human conversation, such as via online chat, to facilitate interaction with their users. The interaction may be via text, graphical interface, or voice - as some virtual assistants are able to interpret human speech and respond via synthesized voices. In many cases users can ask their virtual assistants questions, control home automation devices and media playback, and manage other basic tasks such as email, to-do lists, and calendars - all with verbal commands.
In recent years, prominent virtual assistants for direct consumer use have included Amazon's Alexa, Apple's Siri, Microsoft's Cortana, and Google Assistant. Also, companies in various industries often incorporate some kind of virtual assistant technology into their customer service or support. Recently, the emergence of recent artificial intelligence based chatbots, such as ChatGPT, has brought increased capability and interest to the field of virtual assistant products and services.
