People adapt their language to their conversation partners, for example by using technical terms. Computers, on the other hand, still find it difficult to react individually to different users • Vera Demberg wants to change that. The professor of Computer Science and Computational Linguistics at Saarland University is tackling a key issue of communication: People infer things beyond what is literally said – and everyone makes his or her own assumptions • This fact poses a major difficulty for computers. For her research project on this topic, Vera Demberg has received the prestigious ERC Starting Grant from the European Research Council, which provides 1.5 million euros over five years.
In this research project, Vera Demberg is working with computer systems that can explain or summarize content. So-called chatbots, programs that automatically ask customers about problems and offer them solutions, are an example of this.
"The goal of my research project is to ensure that systems that automatically generate language adapt to individual users in their manner of expression. In this way, I want to reduce misunderstandings and ensure that people can communicate with computers more naturally," says the Saarbrücken-based computational linguist.
Current voice-based computer systems react to a specific user only to a very limited extent, for example by recommending certain products. "People, however, adjust not only the content but also the spoken form of their statements to their counterpart, so that as much as possible of what they say is understood. This is exactly what I want to achieve for computer systems," explains Vera Demberg.
In the future, a computer system should be able to recognize whether it is, for example, talking to an expert or a layperson, and adapt the frequency of technical terms or the sentence length accordingly.
To achieve this, the researcher must first analyze how people understand language on an individual level and how this process can be modeled in a computer. "An essential component of individual language comprehension is what conclusions one draws when hearing an ambiguous statement," explains Vera Demberg.
For example, the sentence "Today Anna arrived precisely at three o'clock" allows two different interpretations: Anna came on time (as always), or Anna came on time (as an exception). Explicitly emphasizing the word "precisely" allows both interpretations.
It is essential to model such individual conclusions, so-called inferences, in a computer so that the system can anticipate and prevent possible misunderstandings. "The project is therefore very interdisciplinary. I am working together with colleagues from computer science, language science and psycholinguistics to get to the bottom of this question," explains Demberg.
As an application for her basic research, Demberg mentions dialog- and task-oriented systems in which facts are explained and summarized or users are provided with a virtual tutor. The new technology could also be used in cars to create driver assistance systems that are able to adapt their language to the traffic situation – just like a real co-driver.
The project, titled "Individualized Interaction in Discourse (IDDISC)," is located at the Saarland Informatics Campus at Saarland University. It is funded by the European Research Council with a grant of 1.5 million Euros over five years, creating five scientific jobs. The award is already the tenth ERC Starting Grant and the 21st award of the European Research Council assigned to a project at the Saarland Informatics Campus. • 9/20

Video views in Q2 increased by 40% and connected TVs grew by 160% as consumption of news and entertainment content nearly doubled during the COVID-19 pandemic
Brightcove Inc published the Brightcove Q2 2020 Global Video Index Entertainment and Media Edition, which found that OTT streaming of entertainment content continued to dominate, even as governments began loosening stay-at-home restrictions. The data suggests that consumers’ media consumption habits may be permanently shifting away from linear TV, cementing streaming as the go-to choice for entertainment viewing.
Brightcove’s Q2 2020 Global Video Index analyzes hundreds of billions of recent data points from Brightcove’s customers globally to provide insights into how viewers are watching video content. The Q2 data shows that consumption of news and entertainment content nearly doubled (40%) from Q1 (23%) – a significant finding considering Q2 typically sees slower growth in video viewing compared to Q1. Looking at the first half of 2020 compared to 2019, the number of views overall is up more than 30%.
“A recent PwC report found that 69% of video users in Australia under 45 years of age say mobile is their top choice for watching streaming video. Our data also supports that fact showing that smartphones – and now and connected TVs – are driving consumers to stream more content than ever,” said Jim O’Neill, Principal Analyst and Author of Brightcove’s Global Video Index. “There’s been a shift in entertainment video consumption, and streaming will now continue to grow and serve as the entertainment medium of choice during the pandemic and beyond.”
Where consumers choose to view their content is also shifting. Connected TVs (CTVs) saw the most growth in Q2 (160% year-over-year), indicating a resurgence in larger screens as the viewing medium of choice for entertainment.
Other notable findings from the Q2 2020 Brightcove Global Video Index that are specific to Australia and New Zealand include:
“2020 has become video’s evolutionary moment, and streaming entertainment video content is one area where we will continue to see growth,” said Jeff Ray, Brightcove CEO. “The crisis has impacted people at an emotional and financial level, making the need for human connection through video content more crucial than ever. We’re seeing this play out with the rise of streaming services subscriptions, indicating that the future of entertainment consumption lies in connected and mobile devices – linear television could soon be of the past.” • 8/20

The world is eager to do business with Africa but finds it difficult to access African markets because of poor infrastructure
By Tonny Tugee
Without a doubt, Africa is one of the world's fastest-growing economic hubs. Crucial to this rate of development is the ability to meet the demand for key infrastructure. At the end of last year, a World Bank economic update reported that Kenya has seen its Information and Communications Technology (ICT) sector grow at an average of 10.8% annually since 2016, becoming a significant source of economic development and job creation with spillover effects in almost every sector of the economy.
While this is hugely encouraging news for Kenyans, it also raises questions about the factors which might impact the ongoing positive trajectory of infrastructure development, both in Kenya and the rest of the continent.
In 2019, Kenya invested US$59 million in the Djibouti Africa Regional Express (DARE) submarine fibre-optic cable system, which reached the shores of Mombasa during March this year. The others include SEACOM, East African Marine System (TEAMS), Eastern African Submarine Cable System (EASsy) and Lion2 systems. According to Njoroge Nani Mungai, Chairman of Kenya's Communications Authority, the investment demonstrates the government's desire to improve Kenya's position as a regional IT hub. It is also aimed at guaranteeing both companies and individuals' access to a faster, more secure, and more reliable Internet connection. Revenues generated by the digital economy should reach US$23,000 billion by 2025, thanks to investments 6.7 times higher than those in other sectors.
In addition, terrestrial fibre networks have continued to expand, offering more connectivity options and better network redundancy – great news for land-locked countries. However, according to MainOne's CEO, Funke Opeke, these remain underutilised due to high prices and a failure to establish an enabling environment.
Mobile network coverage
Telecommunications has continued to register positive growth, with increased uptake and usage of mobile phone services. High-bandwidth Internet infrastructure has become more widely available, while the rollout of 4G infrastructure by the MNOs has already led to substantial growth in subscriptions to data and Internet services. With the expansion of fibre-optic infrastructure across the country, more homes will be connected to better-quality, higher-speed broadband services, which will be extended to the rural areas.
Consequently, the increase in mobile network coverage has led to a decline in fixed-line networks related to voice calls. Alternative solutions need to be considered to ensure a stable Internet connection throughout Kenya to bridge the rural and urban digital development divide.
The world is eager to do business with Africa but finds it difficult to access African markets because of poor infrastructure. Greater economic activity, enhanced efficiency and increased competitiveness are hampered by inadequate transport, communication, water, and power infrastructure. The World Bank economic update, mentioned earlier, highlighted challenges relating to the inadequate power supply, transport networks and communication systems as crucial to ensuring ongoing connectivity, and continental economic development. It found that the poor state of infrastructure in sub-Saharan Africa reduced national economic growth by two percentage points every year and cut business productivity by as much as 40%.
It is estimated that about US$93 billion is needed annually over the next decade to overhaul sub-Saharan African infrastructure. About two-thirds or $60 billion of that is needed for entirely new infrastructure and $30 billion for the maintenance of existing infrastructure. Only about $25 billion annually is being spent on capital expenditure, leaving a substantial shortfall that must be financed.
The economic climate of Kenya will determine access to the tools needed to build the relevant infrastructure. According to André Pottas, Deloitte's Corporate Finance Advisory Leader for sub-Saharan Africa, this translates into exciting opportunities for global investors who need to look past the traditional Western view of Africa as a homogeneous block and undertake the detailed research required to understand the nuances and unique opportunities of each region and each individual country.
The key to unlocking Kenya
With governments across the continent committing billions of dollars to infrastructure, Africa is at the start of a 20 to 30-year infrastructure development boom. Fortunately, we have access to a global network of exports, which we need to be utilising optimally to ensure a stable infrastructure, both digital and physical.
However, in preparation for the boom, the only way for Africa's infrastructure backlogs to be cleared and to unlock connectivity and communications in Kenya is through globally competitive, growth-oriented, mobile, and digital technology businesses. It is imperative to establish partnerships with trusted private sector players who already cater to the local and international communications market with reliable connectivity solutions. • 8/20
