Natural language processing (NLP) is a subfield of artificial intelligence that studies how to process and understand human language, with the ultimate goal of enabling natural communication between humans and computers; it is an interdisciplinary field that draws from computer science, linguistics, psychology and other areas to allow computers to understand, generate and translate between different human languages. NLP techniques include morphology, lexicography, syntax, semantics and discourse analysis to analyze words, sentences and full conversations at different levels of meaning.
Managing Reputation in the Digital Age - Magnus CarterMentor Digital
Magnus welcomes everyone and sets the scene for the valuable and informative talks to follow by talking about how reputation within public sector organisations and charities is very much shaped in three ways; their websites, the media and social media. It is important to have a dialogue with the public, to share information and ensure their support and confidence through a positive image. Magnus demystifies some of the issues you can face and gives some valuable pointers for the future.
NLP
Machine learning
is an interdisciplinary subfield of computer science and linguistics. It is primarily concerned with giving computers the ability to support and manipulate speech. It involves processing natural language datasets, such as text corpora or speech corpora, using either rule-based or probabilistic (i.e. statistical and, most recently, neural network-based) machine learning approaches. The goal is a computer capable of "understanding" the contents of documents, including the contextual nuances of the language within them. The technology can then accurately extract information and insights contained in the documents as well as categorize and organize the documents themselves.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

4. How does NLP work…
• Morphology: What is a word?
• 奧林匹克運動會(希臘語:Ολυμπιακοί Αγώνες,簡稱奧運會或
奧運)是國際奧林匹克委員會主辦的包含多種體育運動項目的國際
性運動會,每四年舉行一次。
• ك
بيوت
ها = “to her houses”
• Lexicography: What does each word mean?
– He plays bass guitar.
– That bass was delicious!
• Syntax: How do the words relate to each other?
– The dog bit the man. ≠ The man bit the dog.
– But in Russian: человек собаку съел = человек съел собаку
5. How does NLP work…
• Semantics: How can we infer meaning from sentences?
– I saw the man on the hill with the telescope.
– The ipod is so small!
– The monitor is so small!
• Discourse: How about across many sentences?
– President Bush met with President-Elect Obama today at the
White House. He welcomed him, and showed him around.

out?

youtube videos, automatic 411, …

– Yesterday, I called out when Art Long vowed to ensure that the four-
star hotel, to live in. I see no future, I rely on it in the 80s may be
regarded as a four-star, and I want the big 368-bed Room, the room
is only one 0.5 m * 1-meter small windows, what we can see, I rely
on, ...
– "本人刚从酒店回来,很想发表一下自己的看法。总体印象:位置很好
,价格也不错,但是服务一般或是太一般了,前台接待的水平和效
率 ..."
– "I came back from the hotel, would like to express my own views. The
overall impression: a good location, good prices, but services in
general or too general, the level of the front reception and efficiency
..."
11. Why is machine translation hard?
• Requires both understanding the “from” language and
generating the “to” language.
• How can we teach a computer a “second language”
when it doesn’t even really have a first language?
• Can we do machine translation without solving natural
language understanding and natural language
generation first?
