Hi What I'm going to talk about is related to the two first presentations we have today here It's about citizen science crowd the data
00:21
It's about citizen science small cities crowd data, how can we Get all this Data and use it On a right way and how not to lose data on the on the way to
00:42
Save it and being able to use it So Well, it's a bit you have Twitter there if you want to participate but it's Well Probably there's nothing important on that place Well, I'm Maria. I work for geocat
01:03
Which is that Dutch company that mostly works with what you see on the right side of the screen We work mostly with your network, but we also work with your server map server a lot a lot of
01:22
Inspire post yes, we also have you got rich if you are interested in knowing. What's this? we have to stand on the we have a booth on the coffee Hall So we participate on an European research project and
01:43
This project started because we noticed that there's a lot of Classically and SDI has Collects data and then the government so the public administrations use this data and And
02:01
The flow of the data is very strict When you enter data on an SDI, it's well formed It's you have checked that it's right. You have checked that has good quality it's only data that has been collected for one goal and you
02:22
Do use it for that wall, but right now there's a lot of different sources. I know that Our friend here says she didn't like the Internet of Things Expression I didn't I don't like it either but it's true that there is some part of it
02:40
There we have or smartphone. Yes, we have smartphones we have Cars that have sensors we have sensors everywhere. We have a lot of different sources for data right now and this data is Being uploaded on the cloud and we want to use it. We don't want it to just
03:03
be for forgotten on the cloud, so First thing is people that build their own the drones or their own sensors and collect data and they upload the data and They want to well share this data But they don't care about if this is well formed if it has errors or maybe they care about it
03:25
But they use a different format that you are expecting we also have People uploading data. They don't know it's real data that can be used That people that tweet about I have seen a car accident on this road or I have I don't know
03:43
I have seen a fire. I'm fleeing from a fire. So this is also data that We it will be good if we can reuse it Well, we also have all these open data movement that is Collecting data open street map is the very big example, but we have more examples
04:05
There's a very big movement of people collecting data on the format that this sometimes is not Sometimes it's it has a good format other times. It doesn't have a good format. So We
04:20
Have data that comes from who knows where it just appears there and we want to use it So on this European research project called the cobweb, you can see it below on the left We try to create free software
04:40
Framework that tries to Interact with all these sources extract data also we have our own Channel to collect data Easy to use for users that are not very technical or not experts, but we can collect that data and
05:03
process it to use later, so The main idea is this one You want to collect some kind of data So you start a survey you say you post on a portal and say, okay, I want to collect data about
05:22
Butterflies because I like butterflies and I want to know what kind of butterflies we have on this area or I want to see birds migrating also or I want to We are focused on Environmental data, but it can be used to anything you can think of maybe I want to collect data about
05:42
car accidents also So people can collect this data. We also get data from different sensors from Twitter from Any social network? We process the data make sure the data is right more or less
06:00
We classify it we conflate it with different sources. So we have we generate data sets These data sets can be published for general purpose or maybe it's not it's sensitive data like with endangered species
06:21
So it's not published for the general public but only for people who ask for access for these data sets Also scientific you use this data to research and these also these These data sets can be reused to create new surveys. For example, if you
06:43
are collecting data about some endangered species and you notice that There they have disappeared from some Area, they should be there. You can start collecting data about what is happening in that area why they are not
07:00
there anymore So when I explain this this is this looks very simple, but when we try to make this on On free open source framework, it's not that easy to To build and to
07:22
Prepare it for general purpose not for just a use case in concrete Also, I don't know. I want to mention that I don't know why people on this conference talk about Open source we should talk about free Source or liver a source because open source is not free as in freedom
07:43
open source is just You have the code, but maybe you cannot reuse it or you cannot modify it free software free code is What is good in this case because you can reuse it you can adapt it you can Free as in freedom not as in free beer
08:03
anyway This Was the general idea so we start developing it We have a lot of different components. This is a very abstract and generic
08:21
Diagram of what cobweb is because this is much more detailed On Friday a panos is here. I don't know exactly when is your on Friday afternoon I think we have another cobweb talk that is going to focus on the mobile part on the PC API mobile app offering to
08:41
but So I'm going to talk about the rest So the idea is mostly what I have talked we have the coordinators we which are the People that are in charge of creating new surveys who decide more or less
09:03
What kind of data they want to collect? so with The tools we have created We have a mobile phone application Which you can? generic mobile phone application Which you can say okay? I'm going to use this survey
09:23
So it downloads a form the coordinator has created and on this form It's very easy to use for users that are not expert because it guides you what kind of data You want to collect what kind of data you want to? Maybe a photo. Maybe you want to check something and
09:43
Then this data gets uploaded You can access well this data goes through a conflation processing to a quality assurance The quality assurance is important here because well We have
10:01
We have to make sure because users are not expert. So we have to make sure the data is make sense Yesterday I think there was a workshop that also talks about this. I don't remember exactly which one was but The
10:20
Thing is that we are talking about people that are collecting data Routing data that may not know exactly what they are doing. So We have to make sure it's right. We have to compare with what other people are uploading of the same Event or area and we also want to conflate it and process it with sensors other
10:47
External sources and I don't know if we already added the Twitter or social networks, but in any case the idea is to get from other sources so you can compare and check if a user is
11:04
Telling what he has to do and then the data is offered by OGC services with your server and It can be reused Also This data we are offering it. I don't know if you know about these five stars of open data
11:28
Open data says that the quality of your data Can be measured in these five stars First level is have your data on the web. We already published the data
11:41
That is an machine readable way machine readable data So it's also machine readable data because we use ontologies We use OGC services Also, it has to be on a non-profit a format OGC services
12:01
RDF standards Geonetwork has an RDF endpoint and well your server office offers the data also in The JSON and I Don't remember there the white and finally a linked RDF. Well, this is not finished but
12:27
At least we have four of the five stars for sure on this data so Let me remember you that this is a framework Does this free source so it can be reused if you are interested in something like this?
12:43
You can go to github search for cobweb. I think the name is cobweb Minos EU So you can check it and reuse it well
13:02
This can be used we focused on environmental data, but this can be reused for any kind of data you want to Make people Upload and then you can reuse the data for anything you want. So
13:20
This is very Easy to readapt to anything you want to do So what are the challenges here because this is not just connecting a few different existing software Pieces of software we have developed For example, the what panels is going to tell you on Friday. This is new almost new development
13:46
About this mobile phone that allows you to create custom forms to upload data Also the catalog had to be adapted to because
14:00
a Geo network, which is what we are used to what we are using It's focused on people that know what they are doing But cobweb is focused to people that doesn't know what they are doing or doesn't are not experts on collecting data Also the data analysis is also a big part of what we have been doing here because
14:25
The quality assurance make sure that the data is right is important then Conflation of the data with other sources also is very important Assurance the data protection and security restriction also is very important because
14:43
At least in Europe, we have very strong privacy laws so for example If someone uploads data, you cannot publish it on a way that Other people can relate that data with the original person unless
15:05
The person who uploads it once that other people knows it. So We have to make sure that we relate the data to the person who has uploaded it But we have to make sure that
15:21
External third-party people cannot make that relationship back Also, we find that the original black tone was very complex for the user and we have to simplify it because again, we are talking about non-expert people and
15:43
What we are trying to do now is adding semantics adding stronger ontologies and in semantics so we can link to other sources so we can make people that When they take the data they can
16:01
Link to the ontologies and know exactly what we are talking about also We have to make sure because we have a lot of trolls. So we have to make sure on the quality assurance that what people upload is not just
16:20
What they want to is true and that is what we are looking for This is Okay, this is the portal it's a geonetwork modified
16:46
I'm not going to show the part of the Of the mobile phone because Panos is going to do it but We already have users
17:00
uploading things here and and You can search the portal and search what kind of Things is are being uploaded if you are interested in maybe doing some
17:21
Collecting some data somewhere we are open for collaborations always and Okay, I closed it and I didn't want to close it
17:44
Generally, I think it's time also, so that's it you have questions
18:20
There's two kind of
18:21
One is protect the uploaders privacy, so Because if someone Usually goes on the weekends to somewhere to collect data. You don't want to know that because then
18:42
someone can enter their home or something, so That's one and the other one is if you are collecting Delegate data like on the endangered species data You don't want people to know where some and then your species live because then they will go there who knows So that's the two main points on privacy here and those are covered with corporate
19:10
yes, you can give privileges to special users to Both upload the data or download the data access the OGC services
19:25
and Well if you are on a Special Survey you are not able to see what other people have uploaded on this same
19:41
Survey on the same kind of data. So just see what you have uploaded Well, there's also the anonymous use case where you don't log in so you can't see almost anything on a private survey, but If you have logged in you can see your own data, but you cannot see what other people have uploaded
20:02
So you only see what you already know? Maybe I some loose but You mentioned some mobile applications to give a special data. What applications? The mobile application
20:23
Panos there say hi He's going to give a talk on Friday. So if you look on the I didn't want to That's why I focus on this apart. Sorry. He's going to explain it because you are going to talk about that, right?
