Touted as the first digital assistant designed specifically for education, this technology opens the door for future problem-solving and educator support. With more and more technology being introduced to the classroom, educators need simple ways to manage the tools at their disposal. Otherwise, tech can be forgotten or unused. Symphony Classroom allows educators to control multiple devices, including the teacher's own laptop, from anywhere in the classroom. The product's hub has numerous USB and HDMI ports to support tech integration and control.

A key distinguishing feature of conversational recommender systems over traditional recommender systems is their ability to elicit user preferences using natural language. Currently, the predominant approach to preference elicitation is to ask questions directly about items or item attributes. These strategies do not perform well in cases where the user does not have sufficient knowledge of the target domain to answer such questions. Conversely, in a shopping setting, talking about the planned use of items does not present any difficulties, even for those that are new to a domain. In this paper, we propose a novel approach to preference elicitation by asking implicit questions based on item usage. Our approach consists of two main steps. First, we identify the sentences from a large review corpus that contain information about item usage. Then, we generate implicit preference elicitation questions from those sentences using a neural text-to-text model. The main contributions of this work also include a multi-stage data annotation protocol using crowdsourcing for collecting high-quality labeled training data for the neural model. We show that our approach is effective in selecting review sentences and transforming them to elicitation questions, even with limited training data. Additionally, we provide an analysis of patterns where the model does not perform optimally.

While we've had weeks of early Black Friday deals already, Thanksgiving has brought additional sales, some of which we expect to continue through Black Friday proper. This has been a trend for the past few years -- if you happen to be online and searching for Black Friday deals a few hours before the day arrives, you can expect at least a handful of solid early sales. And that strategy may pay off this year even more than others as supply chain issues continue to push back shipping estimates. The sooner you grab the items on your gift list, the better the chance they'll arrive on time. To make your search a bit easier, we gathered the best early Black Friday tech deals we could find here.

Amazon's Black Friday sale has kicked off, and there are plenty of deals to be enjoyed on everything from home and garden to kids toys. If you're in search of an affordable smart home device, it's worth noting that Amazon's Echo Dot (3rd Gen) Smart Speaker with Alexa is now reduced to just $19.99. Now 50 per cent off its original price, this is just one of the top discounts offered in the sale, which has been running all week with new discounts dropping every day.

Streaming devices are pretty affordable nowadays, but there are some benefits to opting for a more expensive model like the Apple TV 4K. We consider it to be the best high-end streaming box, and right now it's on sale for $160, which is one of the better prices we've seen. Amazon has the device for $169, but an automatically applied coupon will knock the price down to $160 at checkout. Apple modestly upgraded its set-top box this year with the biggest improvement being the new Siri remote. The previous remote that came with the Apple TV 4K was clunky to use, but this new model is a huge improvement. It's larger and has a touch-sensitive directional pad that makes it much easier to swipe and scroll between content on your screen.

We live in a world where robots and robotic technology have become part of our everyday lives. While films such as "Metropolis" and television series like "The Twilight Zone" warned of a world in which our mechanical creations would enslave us, many of us could not envision a day without virtual personal assistants like Siri or the floor-cleaning robotic vacuum Roomba.

If you're in the market for a budget-friendly smart speaker or two (or three) this Black Friday, it might be worth casting a glance in Amazon's direction. Several Echo devices went on sale last week, and now you can save on more. Among them is the Echo Dot with Clock. It's $35 at the moment, which is $25 lower than the regular price and an all-time low. The Echo Dot is a smaller version of the Echo speaker.

Should I buy a Chromebook or a Windows laptop? It's a common question, whether asked by parents weighing the best computer option for back-to-school or by people who just want an inexpensive computer for themselves. We'll help you choose the right one. Our latest update includes more answers to questions you might have: such as, how slow (and inexpensive) can a Chromebook be before it stops being usable? What does Windows 11 and Windows 11 SE mean for laptops? Read on for the answers, plus our up-to-date buying guide for November 2021 and Black Friday, plus more details and what to buy. A notebook PC or laptop powered by Microsoft Windows offers several advantages. Windows offers the most flexibility to run just about any app, your choice of any browser, and configure antivirus options, utilities, and more. You can tweak and configure your PC as you choose. That convenience demands more computing horsepower, and often a higher price compared to most Chromebooks. Prices can soar into the thousands of dollars, and if you need a powerful PC for gaming or video editing, Chromebooks can't compete, and they don't try to. But you'll find some great deals among our more affordably priced, top Windows picks. See our buying guide to the best laptops for even more options.
