SAN FRANCISCO - Samsung Electronics Co. unveiled a smartphone Wednesday that when folded open can be used as a tablet, becoming the first major manufacturer to offer the feature as it strives to stoke excitement in a slumping market. The South Korean giant also appeared to get the jump on rivals by announcing the first smartphone for fifth-generation -- or 5G -- wireless networks, while stepping up its efforts in artificial intelligence and wearables. The Galaxy Fold, unveiled at a San Francisco event, serves as a smartphone with a 4.6-inch display but also opens like a book to become a 7.3-inch tablet. "We are giving you a device that doesn't just define a new category, it defies category," said Samsung's Justin Denison at the event. The Fold will be available April 26, starting at $1,980, the company said.

The Serious Fraud Office is a specialist prosecuting authority tackling the top level of serious or complex fraud, bribery, and corruption across England, Wales and Northern Ireland. It both investigates and prosecutes its cases, which is unique but necessary because the cases are complicated, and lawyers and investigators need to work together from the outset of them. Supporting both lawyers and investigators is an IT infrastructure that is managed by chief technology officer (CTO) Ben Denison, who also looks after the technology that supports the SFO's operational activities. "That includes digital evidence, so in our cases when we're investigating someone we'll see information from phones, tablets, laptops, and email, and we have a digital forensics team that processes that material and extracts relevant data from it, and it can then be ingested into another system which our case teams use to review it from," Denison tells PublicTechnology. In essence, the SFO ensures that all of the data – whether it's digital or a hard copy – is put into one place, so that it can be reviewed together.

It previously piloted similar technology developed by Canadian firm OpenText during its four-year investigation into fraud at Rolls-Royce which involved reviewing 30 million documents. The SFO said that technology was up to 80% cheaper than using outside counsel to review those documents and identify legally privileged material. OpenText, the "AI lawyer", goes "further than just flagging legally privileged material" an SFO spokesperson told Sky News. "It can also scan and organise information from multiple document types - PowerPoint, Outlook calendar invites, Word documents etc - displaying the information relevant to an investigation on a timeline for an investigator to then review." The SFO told Sky News they expect the system to cost "around £12m over the expected lifetime of 7 years - which is offset against the savings the new tech will bring by enhancing our ability to review and investigate in a targeted way, without solely relying on human review."

The Serious Fraud Office (SFO) had a problem. Its investigation into corruption at Rolls-Royce was inching towards a conclusion, but four years of digging had produced 30 million documents. These needed to be sorted into "privileged" and "non-privileged", a legal requirement that involves paying junior barristers to do months of repetitive paperwork. "We needed a way that was faster," says Ben Denison, chief technology officer at the SFO. So, in January 2016, he started working with RAVN.
