12. SCHWAG ALERT
We’ve got hoodies (as many as you can take)
Prize! Apple TV for best in show using our Image API
Prize! Kindle for best in show using our Text API
We’re hiring!

15. Using the MetaLayer
Text API

16. Our Text API offers methods for extracting contextual features
from text documents using various forms of entity extraction.
•Find place names in documents and turn them into lat/lon
coordinates for mapping
•Perform auto-tagging and classification using uncommon
keywords
•Utilize our sentiment analysis algorithms

17. ARCHITECTURE
Built using pyNLTK (python natural language toolkit)
Brown Corpus (Brown University Standard Corpus of Present-Day
American English)
Extended to deal with short form text like Tweets
Corpus can be extended to optimize the API for specific use cases.
60,000 items per minute on a single server
Scales horizontally for ‘bigger data’ streams

18. FUNCTIONS
Sentiment Analysis
Tagging (Uncommon Keywords)
Location Disambiguation
Bundle (a Buffet of Awesome)

19. FORMAT
Post: “This is some excellent text that needs to be tagged especially if
we can pick the location Philadelphia, PA out of it.”
Response Example: { "status": "success", "method": "bundle", "service":
"datalayer", "response": { "datalayer": { "text": "this is some excellent text
that needs to be tagged especially if we can pick the location
Philadelphia PA out of it", "locations": [ { "latitude":
39.952300000000001, "confidence": 10.0, "name": "Philadelphia, PA, US",
"longitude": -75.162400000000005 } ], "sentiment":
0.63960214906683133, "tags": [ "excellent", "text", "location",
"Philadelphia", "PA" ] } } }

21. Using the MetaLayer
Image API

22. Our Image API offers methods for extracting contextual features
from photos and image documents.
•Find all the objects in a photo along with their relative
coordinates in the frame
•Extract color/histogram profiles
•Parse text from the image to make it actionable

23. ARCHITECTURE
Built using Teeseract OCR with a proprietary training set.
Extensible and Adaptive
20,000 items per minute on a single server
Scales horizontally
Parses JPG and PNG documents

24. FUNCTIONS
Color Profile (all colors in an image)
Histogram (the distribution of color in an image)
Optical Character Recognition (OCR)
Object Recognition
Bundle (Awesome Reloaded!)

25. MetaLayer Dashboard API
*Coming soon young, Padawan.*

26. Our Dashboard API offers methods for interacting with
MetaLayer Dashboard products through scripting.
•Remotely create and configure dashboard environments
•Push data to RESTful Dashboard hook (ex. real-time streams)
•Poll/Request data from Dashboard hook (ex. historic data)
•Analytics from Dashboard activity streams
•Create data mashups, consume the JSON output

27. ARCHITECTURE
Dashboard is build with Python and Django
Adds GUI elements to working with APIs
Drag and drop data science. Anyone can use it to mash up data.
Background tasks distributed across horizontal servers.

28. FUNCTIONS
Control Administration & User Roles
Modify GUI Features
Data Acquisition
Data Consumption
Analytics
