   52  sudo apt-get install mongodb-clients
   53  mongo 'mongodb://mongodb.cms.waikato.ac.nz:27017' -u anupama -p

Failed with
    Error: HostAndPort: host is empty at src/mongo/shell/mongo.js:148
    exception: connect failed

This is due to a version incompatibility between Client and mongodb Server.
The solution is to follow instructions at http://www.programmersought.com/article/6500308940/
and then https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/
as below:

   54  sudo apt-get purge mongodb-clients
   55  sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 9DA31620334BD75D9DCB49F368818C72E52529D4
   56  echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/4.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-4.0.list
   57  sudo apt-get update
   58  sudo apt-get install mongodb-clients
   59  mongo 'mongodb://mongodb.cms.waikato.ac.nz:27017' -u anupama -p
(still doesn't work)
   60  sudo apt-get install -y mongodb-org
The above ensures an up to date mongo client but installs the mongodb server too. Maybe this is the only step that is needed to install up-to-date mongo client and mongodb server?
   72  sudo service mongod status

  103  sudo service mongod start
"mongod" stands for mongo-daemon. This runs the mongo db server listening for client connections
  104  sudo service mongod status
   88  sudo service mongod stop

This is due to a version incompatibility between Client and mongodb Server.
Can find client version above. (2.6.10)
Server version can be found by running the mongo client shell. Doing so without loading a db:

    4.0.13 <<<<<<<<<-------------------<<<< MONGODB SERVER VERSION

(Check Mongo server version: https://stackoverflow.com/questions/38160412/how-to-find-the-exact-version-of-installed-mongodb)

Finally we now know the mongodb server version: 4.0.13
This version doesn't work with our mongo client (shell) version of 2.6.10.

Enable MongoDB's free cloud-based monitoring service, which will then receive and display
metrics about your deployment (disk utilization, CPU, operation statistics, etc).

The monitoring data will be available on a MongoDB website with a unique URL accessible to you
and anyone you share the URL with. MongoDB may use this information to make product
improvements and to suggest MongoDB products and deployment options to you.

To enable free monitoring, run the following command: db.enableFreeMonitoring()
To permanently disable this reminder, run the following command: db.disableFreeMonitoring()

------------------------

Ask Clint to rename "anupama" database to "ateacrawldata" database following the instructions at:
    https://stackoverflow.com/questions/9201832/how-do-you-rename-a-mongodb-database
I don't have permissions to do this.
Nor do I have permissions to create Mongo collections within a new database that I create, like ateacrawldata.
I only seem to have rights to the "anupama" database.

So now mongodb is running on node1 on localhost:27017.

Next, in another x-term connected to analytics' node1 Vagrant VM, port forward node1's localhost:27017 to analytics' localhost:27017:
    vagrant ssh -- -L 27017:localhost:27017



Finally, in another x-term, port-forward from analytics:27017 to current machine's 27017:
    ssh -L 27017:localhost:27017 analytics


Now can connect Robo-3T running on current machine to localhost:27017.

Then in a new x-term, can use the client mongo shell to connect (by default to localhost:27017):
    
    wharariki:[122]/Scratch/ak19/GS309>mongo --shell
    MongoDB shell version v4.0.13

Country code to geolocation CSV file found by Dr Bainbridge:
https://developers.google.com/public-data/docs/canonical/countries_csv

Import into mongodb with:
https://stackoverflow.com/questions/4686500/how-to-use-mongoimport-to-import-csv



NOTE: mongoimport is a commandline utility and not a command to be run from the mongo shell. See https://jira.mongodb.org/browse/DOCS-11072
This means, in an x-term, DON'T RUN MONGO SHELL/client first. Instead, directly from x-term, run the following to import the countrycodes.csv file:


    mongoimport -d ateacrawldata -c countrylocations --type csv --file /Scratch/ak19/maori-lang-detection/MoreReading/countrycodes.csv --headerline

BUILDING TOWARDS NEW MONGODB QUERY: Counts by country code of TENTATIVE NON-PRODUCT SITES that are in Maori
---

# https://stackoverflow.com/questions/16902930/mongodb-aggregation-framework-match-or
# https://docs.mongodb.com/manual/reference/operator/query/and/

# 1. all the websites which are from NZ:
db.getCollection('Websites').find({geoLocationCountryCode: "NZ"}).count()
128

# 2. all the websites that have /mi in URL path which are from NZ:
db.getCollection('Websites').find({$and: [{urlContainsLangCodeInPath: true}, {geoLocationCountryCode: "NZ"}]})
6

# 3. all the websites that don't have /mi in URLpath
db.getCollection('Websites').find({urlContainsLangCodeInPath: false}).count()
1292

# 4. all the websites that don't have /mi, or if they do are from NZ
# (should be the sum of the above points 2 and 3 above)
db.getCollection('Websites').find({$or: [{urlContainsLangCodeInPath: false}, {$and: [{urlContainsLangCodeInPath: true}, {geoLocationCountryCode: "NZ"}]}]}).count()
1298

# 5. All the websites that have at least 1 page detected as MRI AND either don't have /mi un URL path or if they do are from NZ
# These are the TENTATIVE NON-PRODUCT SITES
# Should be less than the point 4, but more than 1 to 3

db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}},{$or: [{urlContainsLangCodeInPath: false}, {$and: [{urlContainsLangCodeInPath: true}, {geoLocationCountryCode: "NZ"}]}]}]}).count()
X 859

Now with http(s)://mi.* also excluded, the above query returns a count of:
389


BUT THIS IS THE CORRECT VERSION OF THE QUERY:
db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}},{$or: [{geoLocationCountryCode: "NZ"}, {urlContainsLangCodeInPath: false}]}]}).count()
389


# 6. Now do the counts by country code of the above, by pasting the query of point 5 as the $match clause (i.e. without the .count() suffix)
# Counts by country code of TENTATIVE NON-PRODUCT SITES that are in Maori
db.Websites.aggregate([
    {
        $match: {$and: [{numPagesContainingMRI: {$gt: 0}},{$or: [{urlContainsLangCodeInPath: false}, {$and: [{urlContainsLangCodeInPath: true}, {geoLocationCountryCode: "NZ"}]}]}]}
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 }
        }
    },
    { $sort : { count : -1} }
]);

The result is very close to the same aggregate on just numPagesContainingMRI.

That's because if you count those websites that contain /mi/ AND numPagesContainingMRI, they're very few:

db.Websites.aggregate([
    {
        $match: {
            $and: [{numPagesContainingMRI: {$gt: 0}},{urlContainsLangCodeInPath: true}]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 }
        }
    },
    { $sort : { count : -1} }
]);


_id count
us      4.0
nz      4.0
au      3.0
ru      1.0
de      1.0

Total: 13 sites that have /mi/ and are detected as having MRI content,
db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}},{urlContainsLangCodeInPath: true}]}).count()
13

Of these 13, the 4 from NZ were already included in steps 5 and 6. So the difference is only 8 sites that are MI.


Let's get a listing of the sites' domains - 3 whose country codes are NOT NZ have NZ TLD!
/* 1 */
{
    "_id" : "nz",
    "count" : 4.0,
    "domain" : [ 
        "http://firstworldwar.tki.org.nz", 
        "http://www.firstworldwar.tki.org.nz", 
        "https://admin.teara.govt.nz", 
        "http://community.nzdl.org"
    ]
}

/* 2 */
{
    "_id" : "us",
    "count" : 4.0,
    "domain" : [ 
        "https://sexualviolence.victimsinfo.govt.nz", 
        "https://follow3rs.com", 
        "http://www.church-of-christ.org", 
        "http://www.mytrickstips.com"
    ]
}

/* 3 */
{
    "_id" : "au",
    "count" : 3.0,
    "domain" : [ 
        "https://rapuatearatika.education.govt.nz", 
        "https://www.kiwiproperty.com", 
        "https://curriculumtool.education.govt.nz"
    ]
}

/* 4 */
{
    "_id" : "ru",
    "count" : 1.0,
    "domain" : [ 
        "http://www.treningmozga.com"
    ]
}

/* 5 */
{
    "_id" : "de",
    "count" : 1.0,
    "domain" : [ 
        "http://www.almancax.com" # Website to learn German, autotranslated
    ]
}


But we're not catching a potentially large number of auto-translated sites, like
- https://www.gigalight.com/all-languages.html
- http://www.hzhinew.com/

https://culturesconnection.com/manual-or-automatic-translation/
Manual Or Automatic Translation?

Automatic translation continues to improve day by day. However, it is still unable to reach perfect levels of accuracy and lacks a natural feel. Will it ever replace human translation?

--------------
Mr Bill Rogers' suggestions for beginnings of trying to sieve out the auto-translated sites:
- skip .com. .co.<tld>. But .co.nz is also used for non-commercial sites or sites that nevertheless have high quality Maori language content.
- change cut-off value of OpenNLP language prediction? But for sentences and overlapping sentences, we're not using the cut-off value, we're just checking the best predicted language regardless of confidence level for this.

- Code for (a range of) loading of language options in auto-translated sites?

====================

# https://stackoverflow.com/questions/20175122/how-can-i-use-not-like-operator-in-mongodb

Info on the sites with Maori language content that are either from NZ or have .nz domain (TLD):

       db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}}, {$or:[{geoLocationCountryCode: "NZ"}, {domain: /.nz$/}]}]})
       
       db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}}, {$or:[{geoLocationCountryCode: "NZ"}, {domain: /.nz$/}]}]}).count()
       183

Inverse: the sites detected as containing at least 1 Maori language sentence that are NOT from NZ NOR have .nz domain ending (TLD):
     db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}}, {geoLocationCountryCode: {$ne: "NZ"}}, {domain: {$not: /.nz$/}}]}).count()
     685

The above two figures correctly add up to a total of 868 sites, which is the number of sites detected as containing at least 1 sentence in MRI:
    db.getCollection('Websites').find({numPagesContainingMRI: {$gt: 0}}).count()
    868

Without those with /mi in path:
    db.getCollection('Websites').find({$and: [{numPagesContainingMRI: {$gt: 0}}, {geoLocationCountryCode: {$ne: "NZ"}}, {domain: {$not: /.nz$/}}, {urlContainsLangCodeInPath: false}]}).count()

Now let's get a listing of all 685 sites to be manually inspected to determine whether they're auto-translated:

/*
db.Websites.aggregate([
    {
        $match: {
            $and: [{numPagesContainingMRI: {$gt: 0}}, {geoLocationCountryCode: {$ne: "NZ"}}, {domain: {$not: /.nz$/}}, {urlContainsLangCodeInPath: false}]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 },
            domain: { $addToSet: '$domain' }
        }
    },
    { $sort : { count : -1} }
]);
*/
db.Websites.aggregate([
    {
        $match: {
            $and: [{numPagesContainingMRI: {$gt: 0}}, {geoLocationCountryCode: {$ne: "NZ"}}, {domain: {$not: /.nz$/}}, {urlContainsLangCodeInPath: {$ne: true}}]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 },
            domain: { $addToSet: '$domain' }
        }
    },
    { $sort : { count : -1} }
]);


We can knock of another 54 non-NZ sites with our new urlContainsLangCodeInPathPrefix field:

   db.getCollection('Websites').find({urlContainsLangCodeInPathPrefix: true, geoLocationCountryCode: {$ne: "NZ"}, domain: {$not: /.nz$/}}).count()
   54


SO, can repeat query with new field "urlContainsLangCodeInPathPrefix":
Number of sites containing >= 1 MRI sentences that are not from NZ or of .nz TLD and which don't contain "/mi(/)" or "http(s)://mi." in URL path:
   db.getCollection('Websites').find({$and: [
                     {numPagesContainingMRI: {$gt: 0}},
                     {geoLocationCountryCode: {$ne: "NZ"}},
                     {domain: {$not: /.nz$/}},
                     {urlContainsLangCodeInPathSuffix: {$ne: true}},
                     {urlContainsLangCodeInPathPrefix: {$ne: true}}
                ]}).count()

   651


REDO THE COUNT BY COUNTRY QUERY FOR THIS:

db.Websites.aggregate([
    {
        $match: {
            $and: [{numPagesContainingMRI: {$gt: 0}}, {geoLocationCountryCode: {$ne: "NZ"}}, {domain: {$not: /.nz$/}}, {urlContainsLangCodeInPathSuffix: {$ne: true}}, {urlContainsLangCodeInPathPrefix: {$ne: true}}]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 },
            domain: { $addToSet: '$domain' }
        }
    },
    { $sort : { count : -1} }
]);


AFTER BUGFIX FOR miInURLPath being set at the correct now:
db.getCollection('Websites').find(
{$and: [
    {numPagesContainingMRI: {$gt: 0}},
    {geoLocationCountryCode: {$ne: "NZ"}},
    {domain: {$not: /.nz$/}},
    {urlContainsLangCodeInPath: {$ne: true}}
]}).count()

220

db.Websites.aggregate([
    {
        $match: {
            $and: [
            {numPagesContainingMRI: {$gt: 0}},
            {geoLocationCountryCode: {$ne: "NZ"}},
            {domain: {$not: /.nz$/}},
            {urlContainsLangCodeInPath: {$ne: true}}
            ]
        }
    },
    { $unwind: "$geoLocationCountryCode" },
    {
        $group: {
            _id: {$toLower: '$geoLocationCountryCode'},
            count: { $sum: 1 },
            domain: { $addToSet: '$domain' }
        }
    },
    { $sort : { count : -1} }
]);

Can inspect websites' pages for whether it's relevant/auto-translated as follows:
    db.getCollection('Webpages').find({URL:/svenkirsten.com/, mriSentenceCount: {$gt: 0}})


* CN: Only 1/113 sites from CN stood out as being of interest: http://kiwi2china.com/
     BUT: it's auto-translated (e.g. Dutch is clearly auto-translated), MRI not in default or any visible drop down list, and the domain changes once you view it in Dutch to https://nl.admission.nz/

* FR: 16 sites from FR
    http://blueheavenisland.com, http://www.blueheavenisland.com - misdetection. French Polynesia
    https://www.lexilogos.com/ -> takes me to NZ website MaoriDictionary.co.nz etc for translating words anyway
    http://kihikihi.fr/ -> travel (blog?). Appears to be Hawaiian related and not Maori.

GETTING TABLE DATA OUT OF MONGO DB:

https://stackoverflow.com/questions/28733692/how-to-export-json-from-mongodb-using-robomongo
"export to file" as in a spreadsheet like to a .csv?

IMO this is the EASIEST way to do this in Robo 3T (formerly robomongo):

 1.   In the top right of the Robo 3T GUI there is a "View Results in text mode" button, click it and copy everything

 2.   paste everything into this website: https://json-csv.com/

 3.   click the download button and now you have it in a spreadsheet.
