chemical weapons inspectors say they have finished gathering samples at the site of an alleged chlorine attack in syria last month. a team from the organisation for the prohibition of chemical weapons said their samples from douma will now be sent for analysis. for the first time since the second world war there will be no nobel prize for literature. the swedish academy which uses the winner of the award is caught up in a crisis of allegations of sexual assault, around the husband of one of the academy'sjudges. the around the husband of one of the academy's judges. the academy has now decided that the damage to its credibility was so serious it would have no choice but to cancel the awards. churchill, steinbeck, dylan. for more than a century, the nobel literature prize has been amongst the most prestigious awards for authors from around the world. but the institution that hands out the literature award, the swedish academy,

has been in turmoilfor months. it's all because of this french photographer, jean—claude arnault, who ran a cultural project that got funding from the swedish academy. he's accused of sexually assaulting at least 18 women and leaking information about prizes. he is married to katarina frostenson, who was a member of the academy when the allegations came out. she later resigned, alongside a handful of others, amid deep internal rows about how the allegations were handled. so it's a big deal that the swedish academy hasn't really been able to cope with this scandal. but also the fact that they haven't expressed any remorse, any regret about their behaviour in public in the last few weeks. the swedish academy's decision to postpone the prize is an admission that it's lost credibility, both here in sweden and around the world. in a statement today, it said it would spend the next year looking at how to tackle conflict of interest and communication in future, as well as recruiting new members. this is a scandal that's notjust put the literary sphere in a spin, but upset a lot of people

across sweden where sex assault allegations are taken seriously, and the nobel awards are a source of national pride. they haven't taken the questions seriously about the sexual harassment. it's such an honourable group of people are acting like kids. i think it is bad for sweden because a lot of swedes think that the swedish academy are the good guys, the people who do good and want to do good. restoring public confidence in the academy and the prize won't be an easy assignment. reporter: there he is. in a moment we'll have newswatch — but first here's click we are becoming aware of how

much data we give away without even realising it. our habits online can say a lot about our personalities, but when we are out and about, what does our behaviour in the real world say about us? well, in the uk, we're all getting used to the fact that we are being filmed by cctv a lot the time. but although a human can tell a lot about a person just by looking at video footage, that is a really hard job for a computer to do. that said, this system is having a pretty good guess at who is looking at right now. it's a very flattering guess actually, but probably no worse than a human would guess given the same footage. this system is an artificial intelligence that researchers at southampton university have trained to estimate

the gender, age and a description of everyone that falls under the gaze of their test cameras. we have millions of images, different types of people captured from different environment, from all around the world, and we hand—label these. they are labelled by human beings as male or female, or 16—30, and the magic part is that we can feed these into a machine, into a computer, to learn what it means to look male, what it means to look female, just from the visual cues alone. the team are pitching this at retailers, as an improved way of measuring footfall — instead ofjust counting the number of customers who come into a store, this can tell shopowners whether the right kind of people, the shop's target audience, are being drawn in. rather than know that 100 people came in and we sold 50 things, we can tell them that 50 people from their target demographic came in and they sold 50 things, so now they know how they are converting certain types of people, who they are converting. retailers would get

a breakdown through each day of the most popular spots in store and the most popular routes taken through the store by each type of customer. and with this high street view here, you can see which shop windows are more grabby and how long people dwell on different areas. in this example we can see carphone warehouse actually has a higher proportion of females walking past it than gap on the other side of the road, which might indicate that maybe gap should move their placement along the high street as this side of the street sees more of its target demographic. this kind of profiling of humans by computer systems has many uses, from this kind of aanonymised retail analysis, to other areas that my say more about us as people. one of the more controversial uses for ai is in policing. marc cieslak travelled to durham to find out more. peterlee police station in county durham.

the early hours of the morning. the man pictured here in the station's cctv, let's call him steve, has been arrested for possession of heroin. your arrest is on suspicion... here in durham the police are trying ai software which could help make decisions about suspects being held in custody. after steve has been processed, the custody sergeant will enter his details into a system called the harm assessment risk tool, or hart. it is an ai tool designed to help custody sergeants make decisions about what to do with a suspect. what it does algorithmically, it uses all of our data to tell us who is high risk of reoffending, medium risk of reoffending, and low risk of reoffending. it is not absolutely perfect, but it gives us a really clear indication of who might commit crime in the future. the ai is trying to

identify repeat offenders who, rather than being sent to court, will be entered into a rehabilitation scheme called checkpoint. this is the first time an ai system like this has been used in the uk. i put my name in here... the system is now searching for the prisoner, we will click on the list, the system will decide if i am at low risk and the sergeant would be presented with... "low—risk — the subject is not likely to reoffend in the next month." so if the sergeant has decided this person will be remanded in custody, they will be refused bail and go to court the next morning. it is a different story for steve. he has a long list of previous convictions including drug possession, assault and driving offences. the ai assesses the data that durham constabulary holds on him and makes this recommendation.

he can only enter checkpoint if it rates him as a moderate risk. everyone who works with the hart project i spoke to is keen to stress that the information it provides is advisory only and the human custody sergeant makes all the final decisions. but the use of this technology in general is, for some people, cause for concern. this kind of artificial intelligence system in policing relies on big data. and that means people's privacy is at risk, and it risks us moving more towards a surveillance state. but it also risks discrimination, because patterns that exist in data already risk being perpetuated and repeated. and there is very little accountability over it. cambridge university's criminology lab is the birthplace of technology being used by the police in durham. it has been in development

for five years. the decisions that hart makes are based on historical data. it uses this information to predict the future outcomes. our artificial intelligence, is looking to the past and the patterns we have observed, to predict the future. we know that the past is not perfect — humans are making decisions, and humans are making predictions in the criminaljustice system. back in peterlee's police station, steve has been assessed and accepted into the checkpoint programme. he ended up spending around eight hours in police custody. what is the future of this kind of technology? in terms of how i see it developing, i think over the next five years

there will be a proliferation of these kind of tools, i think going forward society will come to accept them more, but human beings, government, society, needs to stamp its foot little bit about it. and the reason i say that is because we need to have more regulation. a few years back, wearables became the buzzword. but this year, there has been a lot of talk about hearables. now, that could mean a personal training session or real—time translation directly into a pair of earbuds. but this week, i'm putting to the test a few devices that aim to give you a hearing test and, as a result, optimise what you are listening to. even for those of us who are unaware of having any defect,

the chances are our lifestyles will have had some impact on our hearing and due to this, we don't all hear things in exactly the same way. we have a huge range of hearing, from 20 hertz to 20,000 hertz, and there are various causes of different type of hearing impairment, so we could have a hearing loss through ageing, it could be through noise—induced hearing element as well. but can some headphones balance this out, and do we actually need them to? i popped into one of our peaceful radio studios to find out. so first of all, i have these audera headphones. now, i need to do a hearing test to create my profile. what we're doing here is finding the quietest part of my audible range throughout all the different frequencies. it takes about ten minutes to go through this whole process for a full range of sound on both ears. ok, so the results of my test. i can tell that each ear seems to hear differently from each other but beyond that, obviously, it doesn't mean a huge amount. but what i can do now is i can put the headphones to the test. shouts: 0k, sorry if i'm shouting! this is at 0% now! let's apply 50%!

well, it sounds a lot cleaner! the sound is a lot sharper! you can hear each element of the sound really clearly! the clarity at 100% is pretty good. so what do the experts make of the concept? with the auderas, it uses a basic form of pure tone audiometry. this is something that we perform every day in the clinic and it involves presenting different pitches and different tones and then measuring how loud we have to make it in order for someone to be able to hear it. auderas are stating that they take that into account with the settings on the headphones, and then incorporate that, giving extra sound in the area to compensate for any hearing loss. the mimi music app works in a similar way and has been around a few years. after creating your earprint, it aims to optimise the music you listen to through any wired headphones. here i have the nurophone headphones which look pretty interesting for a start as they're sort of in—ear and over—ear. but they work differently. instead of asking you whether you can hear something, they do the test for you, and they do it in just 60 seconds. they claim to do so by sending sound waves into your ear which will trigger a reaction, sending electrical impulses to your brain and sound

waves back out your ear. it's through measuring them that the app will create what it calls your hearing signature. in my not—very—scientific experiment here, i am noticing a much bigger difference between the generic and the personalised in these headphones. the music sounds totally different. it's different parts of the music that sound louder. and that's mixed in with just a real clear, crisp sound. but our expert had some questions over this upgrade of sound quality. they do give you the opportunity with the headphones to be able to compare the generic settings with those taking into account your personal profile. there was a hugely marked difference between those two things when i actually tested them out on my hearing, which actually prompted me to go downstairs and use our diagnostic 0to—acoustic emission test and see if i had normally functioning ears, which i did — so in terms of the reliability of that, in terms of the accuracy of how they actually come to those conclusions, i'm not entirely sure. but would i want either of these over another pair of headphones at the same price point?

maybe the fact is that i don't need them. if my hearing was a little more damaged, there would be greater rewards to reap. and that is it for the shortcut of click this week. the full version is up click this week. the full version is up on iplayer, and we are also one facebook and twitter. hello, and welcome to newswatch with me, samira ahmed. was bbc news more interested in forcing home secretary amber rudd out of herjob than justice? and why did the name and address of this woman who asked to be kept anonymous appear on screen? justice for the windrush generation.
