TourBERT: A pretrained language model for the tourism industry Artificial Intelligence

Tourism is one of the most important economic sectors in the world (Hollenhorst The Bidirectional Encoder Representations et al., 2014), and its services have many from Transformers (BERT) is currently the characteristics that distinguish them from most important and state-of-the-art natural other products. Services are not tangible language model (Tenney et al., 2019) since and cannot be tested in advance, which is its launch in 2018 by Google. BERT Large, why the customer assumes an increased which is based on a Transformer risk before starting the trip. The service is architecture, is considered one of the most co-created together with the customer, so powerful language models with 24 layers, the customer is an active co-creator of the 16 attention heads, and 340 million service. Services are subject to the unoactu parameters (Lan et al. 2019). BERT is a principle, which means they are pretrained model and can be fine-tuned to produced at the same time as they are perform numerous downstream tasks such consumed, and they are considered as text classification, question answering, bilateral, i.e. a reciprocal relationship sentiment analysis, extractive between persons (Chehimi, 2014). In summarization, named entity recognition, addition, tourism services are relatively or sentence similarity (Egger, 2022). The expensive compared to everyday products model was pretrained on a huge English and have an intercultural dimension.

How to Visualize Text Embeddings with TensorBoard


A word embedding is any method which converts words into numbers, and it is the primary task of any Machine Learning (ML) workflow involving text data. Independently from the problem being faced (classification, clustering, …), leveraging an effective numeric representation of the input text is paramount to the success of the ML model. But what is an effective numeric representation of text? Basically, we want to embed a word in a number or a vector able to convey information about the meaning of a word. One way to intuitively appreciate this concept is provided by word analogies¹, i.e. relationships of the form: "word₁ is to word₂ as word₃ is to word₄".

Roadmap to Natural Language Processing (NLP) - KDnuggets


Natural Language Processing (NLP) is the area of research in Artificial Intelligence focused on processing and using Text and Speech data to create smart machines and create insights. One of nowadays most interesting NLP application is creating machines able to discuss with humans about complex topics. IBM Project Debater represents so far one of the most successful approaches in this area. All of these preprocessing techniques can be easily applied to different types of texts using standard Python NLP libraries such as NLTK and Spacy. Additionally, in order to extrapolate the language syntax and structure of our text, we can make use of techniques such as Parts of Speech (POS) Tagging and Shallow Parsing (Figure 1).

Gefilter Fish: Finding concise topics from Amazon's customer reviews


Patrick Lestrange was an Insight Data Science Fellow (Winter 2018) from Insight's second Seattle session. In his first four weeks at Insight, he built a Chrome extension for Amazon customers to easily identify useful topics in customer reviews. Previously, Patrick was a postdoctoral researcher at the University of Washington, where he also received his PhD in Chemistry in May 2017. He is now a Data Scientist at Boeing, working on pilot-less airplanes. Like over 75% of Americans, I do most of my shopping online with Amazon in part because their wealth of product reviews allows me to make smart choices as a consumer.

Market Segmentation in the Emoji Era

Communications of the ACM

Ishaan and Elizabeth, both graduate students in business, are attending a marketing strategy lecture at a business school in the Northeast. While learning about the principles of market segmentation, Ishaan texts "outdated" followed by three thinking--face emojis to Elizabeth. He wonders how demographic-, geographic-, or psychographic-based segmentation--the topic of the lecture--can help his family's franchise restaurant deal with the hundreds of sometimes-not-so-positive online reviews and social media posts. Meanwhile, Elizabeth hopes that the fast-food restaurant where she ordered her lunch understands that she now belongs to the segment of'extremely displeased' customers. Earlier, she used the restaurant's new app to order a burrito without cheese and sour cream, only to discover that the meal included both offending ingredients. Her lunch went straight into the trash can and she angrily tweeted her disappointment to the restaurant. This simple vignette illustrates an important point. Organizations of every size are challenged with capitalizing on enormous amounts of unstructured organizational data--for instance, from social media posts--particularly for applications such as market segmentation. The purpose of this article is to give the reader an idea of the challenges and opportunities faced by businesses using market segmentation, including the impacts of big data. Our research will demonstrate what market segmentation might look like in the near future, as we also offer a promising approach to implementing market segmentation using unstructured data.
