Indeed, commercial task-oriented dialog systems in the form of smart devices like Amazon's Alexa are used by millions of people every day. Within the academic research community, however, task-oriented dialog system models are often benchmarked on relatively few evaluation datasets. This is in spite of the fact that the past few years have seen a substantial growth in the number of available datasets for building and evaluating intent classification and slot-filling models for task-oriented dialog systems. Thus, the goal of this survey is to catalog these intent classification and slot-filling datasets to help facilitate their use in building and evaluating dialog systems and beyond. Other surveys have discussed dialog datasets in depth (Serban et al. 2018), but exclude almost all intent classification and slot-filling datasets, and model-focused surveys on dialog systems mostly focus on models and pay much less attention to datasets.

Late last year, Valerie Peter, a twenty-three-year-old student in Manchester, England, realized that she had an online-shopping problem. It was more about what she was buying than how much. A fashion trend of fuzzy leg warmers had infiltrated Peter's social-media feeds--her TikTok For You tab, her Instagram Explore page, her Pinterest recommendations. She'd always considered leg warmers "ugly, hideous, ridiculous," she told me recently, and yet soon enough she "somehow magically ended up with a pair of them," which she bought online at the push of a button, on an almost subconscious whim. "They're in the back of my closet," she said.)

AI is changing the marketing world by automating tasks, making them easier for marketers to complete, and increasing their productivity. With all this talk about AI, you may be wondering what exactly does AI mean? According to Wikipedia: Artificial Intelligence (AI) is a field of computer science that focuses on creating intelligent machines. It involves building systems that think as humans do. A typical example is Siri or Alexa. These programs mimic human interactions with users, and they speak to people and understand natural language conversations. In practice, AI refers to any technology used to create intelligent software, robots, or other machines that work like humans. Examples include advanced search algorithms, natural language processing, machine learning, expert systems, neural networks, speech recognition, image recognition, video games, self-driving cars, virtual assistants, chatbots, autonomous drones, and so much more. In short, AI is a branch of computer science that deals with the concept of creating thinking machines. We live in a society where everyone is always looking at their smartphones.

Hear from top leaders discuss topics surrounding AL/ML technology, conversational AI, IVA, NLP, Edge, and more. Ankit Sirmorya, Amazon's machine learning (ML) engineering manager, is an emerging thought leader in the artificial intelligence (AI) and ML space. He serves as the community lead for Global AI Hub, a group dedicated to AI that is growing at a rapid pace. He reviews software engineering and data science-related books and provides feedback after in-depth analysis. Sirmorya also has a YouTube channel, Tech Takshila, which has a worldwide audience.

WELCOME to the future, where artificial intelligence (AI) systems augment, automate or replace human decision-making. Imagine applying for a bank loan through an online system; you key in all pertinent information and almost instantaneously, the system informs you that you do not qualify for a loan. Coincidentally, you know that a friend with a profile very similar to yours got his loan approved by the same system. Let's look at a second scenario: you decide to look for a new job – you send your resume to an online hiring system that immediately tells you you're not a right fit. A peer of yours who you think does not qualify has better luck.

Bundle recommender systems recommend sets of items (e.g., pants, shirt, and shoes) to users, but they often suffer from two issues: significant interaction sparsity and a large output space. In this work, we extend multi-round conversational recommendation (MCR) to alleviate these issues. MCR, which uses a conversational paradigm to elicit user interests by asking user preferences on tags (e.g., categories or attributes) and handling user feedback across multiple rounds, is an emerging recommendation setting to acquire user feedback and narrow down the output space, but has not been explored in the context of bundle recommendation. In this work, we propose a novel recommendation task named Bundle MCR. We first propose a new framework to formulate Bundle MCR as Markov Decision Processes (MDPs) with multiple agents, for user modeling, consultation and feedback handling in bundle contexts. Under this framework, we propose a model architecture, called Bundle Bert (Bunt) to (1) recommend items, (2) post questions and (3) manage conversations based on bundle-aware conversation states. Moreover, to train Bunt effectively, we propose a two-stage training strategy. In an offline pre-training stage, Bunt is trained using multiple cloze tasks to mimic bundle interactions in conversations. Then in an online fine-tuning stage, Bunt agents are enhanced by user interactions. Our experiments on multiple offline datasets as well as the human evaluation show the value of extending MCR frameworks to bundle settings and the effectiveness of our Bunt design.

Social media marketing plays a vital role in promoting brand and product values to wide audiences. In order to boost their advertising revenues, global media buying platforms such as Facebook Ads constantly reduce the reach of branded organic posts, pushing brands to spend more on paid media ads. In order to run organic and paid social media marketing efficiently, it is necessary to understand the audience, tailoring the content to fit their interests and online behaviours, which is impossible to do manually at a large scale. At the same time, various personality type categorization schemes such as the Myers-Briggs Personality Type indicator make it possible to reveal the dependencies between personality traits and user content preferences on a wider scale by categorizing audience behaviours in a unified and structured manner. This problem is yet to be studied in depth by the research community, while the level of impact of different personality traits on content recommendation accuracy has not been widely utilised and comprehensively evaluated so far. Specifically, in this work we investigate the impact of human personality traits on the content recommendation model by applying a novel personality-driven multi-view content recommender system called Personality Content Marketing Recommender Engine, or PersiC. Our experimental results and real-world case study demonstrate not just PersiC's ability to perform efficient human personality-driven multi-view content recommendation, but also allow for actionable digital ad strategy recommendations, which when deployed are able to improve digital advertising efficiency by over 420% as compared to the original human-guided approach.

There are many fears out there when it comes to artificial intelligence – some rational, some irrational. By now, most people have integrated some form of artificial intelligence (AI) into their daily lives. For example, if you use Alexa to check the weather or ask Siri to tell you jokes, that's AI. However, despite the widespread use of such technology around the world, people are still concerned about AI. While many fears are valid – such as AI taking over certain jobs, or making humans lazier – others are unfounded.

Have you ever given any thought to how digital assistants like Siri can accurately understand our speech and return highly specific answers? Or have you ever tried to delve into the Alexa schematics just to empathize better with this virtual assistant? I bet not, and that is exactly why you need to get even more familiar with a term called NLP or Natural Language processing. NLP is one of the major AI technologies aimed at making machines capable enough to interpret speech and text-based human language. And if you are still unsure about the utilities involved, NLP forms the backbone of several common tools like chatbots, grammar checkers, translation software modules, spam filters, and even scaled search engines.

Various efficient and robust product recommender systems using machine learning algorithms are helpful in filtering and exploring unseen data by users for better prediction and extrapolation of decisions. These are providing a wider range of solutions to such challenges as imbalanced data set problems, cold-start problems, and long tail problems. This book also looks at fundamental ontological positions that form the foundations of recommender systems and explain why certain recommendations are predicted over others.
