HybridQA: A Dataset of Multi-Hop Question Answering over Tabular and Textual Data

arXiv.org Artificial Intelligence

Existing question answering datasets focus on dealing with homogeneous information, based either only on text or KB/Table information alone. However, as human knowledge is distributed over heterogeneous forms, using homogeneous information might lead to severe coverage problems. To fill in the gap, we present \dataset, a new large-scale question-answering dataset that requires reasoning on heterogeneous information. Each question is aligned with a structured Wikipedia table and multiple free-form corpora linked with the entities in the table. The questions are designed to aggregate both tabular information and text information, i.e. lack of either form would render the question unanswerable. We test with three different models: 1) table-only model. 2) text-only model. 3) a hybrid model \model which combines both table and textual information to build a reasoning path towards the answer. The experimental results show that the first two baselines obtain compromised scores below 20\%, while \model significantly boosts EM score to over 50\%, which proves the necessity to aggregate both structure and unstructured information in \dataset. However, \model's score is still far behind human performance, hence we believe \dataset to an ideal and challenging benchmark to study question answering under heterogeneous information. The dataset and code are available at \url{https://github.com/wenhuchen/HybridQA}.


5G Commercialization and Trials in Korea

Communications of the ACM

Since Korea has a limited ICT R&D fund compared to other IT global countries, its strategy was essential to achieve its global competence in each generation of mobile communication. Just after the rollout of the world's first 5G service, the government took the next step by announcing the 5G strategy to promote the 5G application to a wide-ranging industry and create a sustainable 5G ecosystem leading to new growth engines. In this article, we focus on the government-industry 5G collaborations, including the R&D roadmap and promotion to the 5G commercialization, the global collaboration, the first 5G experience, and 5G vertical trials to make the 5G-enabled industrial transformation take place in Korea. The development of an electronic digital switching system called TDX in the 1980s, the world's first CDMA mobile service in the 1990s, and the nationwide wired and mobile broad Internet networks in the 2000s are the key advances that made it possible for Korean consumers to easily adopt new technologies such as LTE and 5G. In 2018, the handset penetration rate of South Korea was similar to western Europe, where LTE adaption was 84% with 99.95% coverage and 65Mbps downlink capacity.4


Olympic orbiter: 'Gundam satellite' hitches ride to ISS to promote 2020 Games

The Japan Times

A microsatellite carrying model robots from the popular science fiction anime "Mobile Suit Gundam" was successfully launched to promote the Olympics, organizers said Saturday. The so-called G-Satellite, which contains two figurines from the animated series, hitched a ride to the International Space Station on Friday aboard a SpaceX/Dragon cargo flight from Cape Canaveral, Florida. It will reach the ISS on Monday at 8 p.m. Japan time. The satellite will be released into orbit in the latter part of April and will circle Earth during the Olympics and Paralympics, marking the first time a satellite is used to celebrate the games. According to organizers, the satellite, which has an electronic bulletin board and seven small cameras, will send back images of the robots and messages displayed in English, French and Japanese.

#artificialintelligence

Atos, a global leader in digital transformation, today announced the delivery of its high-powered artificial intelligence, Codex AI Suite, to analyze data and predict attraction performance for Triple Five Group's American Dream retail and entertainment complex. This modern IoT and machine learning platform will enable American Dream to reduce downtime, increase guest satisfaction and lower maintenance costs. Atos' Codex AI Suite collects and stores data from hundreds of ride sensors, which feeds into an algorithm that detects apparent trends, anomalies and unique identifiers of a machine's state. It is an easy-to-use, efficient and cost-effective solution to help American Dream rapidly build and deploy artificial intelligence applications, better extract value from data and develop new business opportunities. The solution will establish a baseline of data analytics using historical data captured from the ride controller and activated through apps rendering on any device.


Across the Language Barrier

Communications of the ACM

Waverly Labs' Ambassador, an over-the-ear translation device, can support up to 20 languages and 42 dialects. The greatest obstacle to international understanding is the barrier of language," wrote British scholar and author Christopher Dawson in November 1957, believing that relying on live, human translators to accurately capture and reflect a speaker's meaning, inflection, and emotion was too great of a challenge to overcome. More than 60 years later, Dawson's theory may finally be proven outdated, thanks to the development of powerful, portable real-time translation devices. The convergence of natural language processing technology, machine learning algorithms, and powerful portable chipsets has led to the development of new devices and applications that allow real-time, two-way translation of speech and text. Language translation devices are capable of listening to an audio source in one language, translating what is being said into another language, and then translating a ...


South Sudan's Olympians in love with Japanese language -- as well as real track in Gunma

The Japan Times

They are trying to get a head start, and unlike most of the 11,000 athletes who will be in Tokyo for the games, and thousands more for the Paralympics, they will be able to speak Japanese. "Just the language itself, I love it," said Abraham Majok, a runner who arrived in Japan in November with three other South Sudanese athletes and a coach. "And it's nice and since we started learning it. But, you know, we are moving well with it and we just love it." They are training northwest of Tokyo in Maebashi, Gunma Prefecture, supported mainly by donations from the public.


AI Facial Recognition and IP Surveillance for Smart Retail, Banking, and the Enterprise

#artificialintelligence

Facial Recognition technology detects faces in the camera's field of view and matches them against faces previously stored in a database. Anti-spoofing is provided through liveness testing without the need for a stereo or a 3D camera. Face Recognition technology is now taking a further step as it is being combined with IP surveillance. Gemalto, a part of the Thales Group and a company that focuses on Digital Identification and Data Protection in order to counter the two root causes of cyberattacks, identity theft, and unencrypted data, defines Facial Recognition as the process of identifying or verifying the identity of a person using their face. It is a technology that captures, analyzes, and compares patterns based on the person's facial details.


Incredible moment a British Paralympian swimmer takes her first steps wearing a robotic exoskeleton

Daily Mail - Science & tech

Incredible footage shows the moment a British Paralympian swimmer with cerebral palsy stands up and takes her first steps wearing a robotic exoskeleton. Grace Harvey, 21, was able to take the special walk with the help of state-of-the-art technology developed in Japan -- giving her a day she will never forget. In the video, the swimmer from Ware, Hertfordshire, smiled nervously as she took her'first' tentative steps. She went on to giggle when a bystander said'You're running, Grace.' Swimmer Ms Harvey holds the European record for the 200 metre (656 feet) Individual Medley and is presently the British number one in the 100 metre (328 feet) backstroke event. She is currently training in the city of Suzuka, Japan, ahead of the 2020 Tokyo Paralympics in August.


Artificial Swarm Intelligence In The Context Of Singularity

#artificialintelligence

Technical singularity is defined as a hypothetical future of superhuman machines with a cognitive capability far beyond the capacity of human minds. In the journey toward this potential technology revolution is something that I have been focused on called artificial swarm intelligence. A starling murmuration, something that people have told me is awe-inspiring, is a marvel of nature similar to an army of ants or a swarm of bees. How do all these individual entities organize around a common mission that includes a form of collaboration and unified orchestration as a team? When thinking about swarms of AI bots or even nanobots, the foundational concept we want to define is what exactly AI bot are.


Plain Japanese, please: Amid tourism boom, easy form of language could help ease communication

The Japan Times

With Japan targeted by an ever increasing flood of visitors, the plain form of Japanese is spreading as a more inclusive means of communication in situations ranging from disasters to tourism. "Every language must be respected, and when we communicate with people who don't speak Japanese, responding in their native language should be a priority," said Akira Yoshikai, head of Yasashii Nihongo Tourism Kenkyukai, a group that promotes plain Japanese and its potential in tourism. "But when it's not practical to do so at an individual level, plain Japanese could be another option," he said. This form of the language targets those who can use Japanese to navigate tasks like shopping and making plans with friends, according to a research group at Hirosaki University in Aomori Prefecture. It uses all three components of the writing system -- hiragana, katakana and kanji -- but at the second- or third-grade elementary school level.
