spam detection using google prediction api - social-networking

I am looking for example to build a spam detection service in a social network. For example: identify a user posted comment as spam on a social network site (such as facebook). I don't have any training data. Does the google API have its own training data set, that can help me identify spam in user posted comments. How does that work? I need something to seed the algorithm with

What actions can we take with google recaptcha enterprise

I have been using Google reCaptcha V2 (Invisible recaptcha) for a long time and we know that if some spammer or bot is trying to call our API then the user will get a puzzle to solve. What will happen if I use the Google Enterprise solution, in this case, Google API will simply return the score based on the action taken by the user?
What if spammer buys a fresh new IP range and is trying to call our APIs, How frequent the google returns the low score that particular IP.
I have seen on my website that spammer used to call APIs with new IP every time, so need to check how google detects this as a spammer.
The score-based site key is the currently recommended type. You are correct that there is no challenge or puzzle in this case.
https://cloud.google.com/recaptcha-enterprise/docs/choose-key-type
While the IP is a part of what determines the score, it is far more complex than that, and having malicious users or bots simply change their IP address will not circumvent the bot detection, the algorithm is quite sophisticated.
The exact details of what signals the score is based on is proprietary and Google holds those details close to the chest, because if adversaries knew those details they could attempt to make workarounds for their bots.

Use of Google Fit API in medical device

I would like to use the Google Fit API for a medical app in France. The Google Fit data would only be used for the fitness part of the app and would be displayed in graphs for reading purposes.
I saw this in the Terms and Conditions of Google Fit API :
Google does not intend Google Fit to be a medical device. You may not use Google Fit in connection with any product or service that may qualify as a medical device pursuant to Section 201(h) of the Federal Food Drug & Cosmetic (FD&C) Act.
As the app will only be available in the European Union, do the same conditions apply to it ?
I'm sorry if this is the wrong place to ask this kind of questions but I couldn't find any email address for Google API support.
Thank you

Yahoo, Google, Yelp API

Is there any php API to gather information about a business(address, reviews) by its phone number from Yelp, Google, Insiderpages, Yahoo..
Please help, i have done research about these, but did't get the right info, though yelp is providing info by it's phone number but there they ask ywsid as mendatory (http://api.yelp.com/phone_search?phone=1234567890&ywsid=XXXXXXXXXXXXXXXX) but i want by phone number only.
Please note that all APIs have terms, most of them won't allow you to store their data in your own database and most of them have display requirements, before proceeding with any developing please read carefully their display requirements and terms.
Depending on your project you might not be allowed to use the data as you might need/want to on your project.
The other alternative would be scrapping sites, but most sites have rules against scraping too...
And again read a lot before putting too effort on something you are prohibited to in first place.
Yelp
ywsid = API key, you need to get your own key if you are using the yelp API, get it here
if you are using it to add it to your own database or storing the information anywhere it is against their policies display requirements & api terms.
if you are using any API you must read their terms before even thinking of doing anything.
Google Places
API
Insiderpages
I Don't think they have one but you could use the citygrid API that does a [lot of sites] search at once.
Yahoo
Yahoo API
CityGrid
As mentioned before citygrid API
Foursquare
Foursquare API
Merchant Circle
Merchant Circle API
White Pages
White Pages API
Yellow Pages
Yellow Pages API
Bottom line is, all these companies have put a lot of time and effort and money to build their databases, and they want you to redirect people back to their pages so they can make their money back/profit.

Using linkedin API, which is the better way of know when was accepted my invitation

Which is the best way of know when was accepted an linkedin invitation using API?
I'm developing a social search web site using linkedin among other social networks.
In my site, any user, can add many linkedin user account to your site account, for then find people from linkedin using Linkedin People Search API (http://developer.linkedin.com/docs/DOC-1191.html)
with the peoples found, i could be to send and invitation or a direct message, depend of the level connection of linkedin account using for that...
Then, using Linkedin API, what is the best way to monitoring when the invitation was accepted?...
Per the documentation, there is no way to directly monitor messages or invitations that you send via the API to another user. So you'll need to come up with some way to monitor this off-line if it is something that you really need. One idea would be to keep track of the ID of the member's you are sending invitations to, and on subsequent (or periodic) calls to the Connections API, you could scan the returned list to see if any of the stored ID's are now connections, and take the appropriate action.
Hope this helps!

How is adwords built?

I want to know how an advertising network like adwords is built. What kind of systems display the ads and what kind of systems search keywords in the content of the publisher's website.
Google has a spider which indexes the content of pages on its adsense network. The ads are pulled in with JavaScript. The actual algorithms which decide what ads to display on a page are closely guarded secrets. Google uses Python a lot, so odds are most of the backend uses that.
To make this question approachable you need to specify what level/type of detail you want/need. Are you looking for a broad understanding of the information architecture and flow? do you need search/parse algorithms pseudo code/code? what exactly do you need?
