This document provides an overview of Delve and the Office Graph for IT professionals and administrators. It describes what Delve and the Office Graph are, how they work, and how content is populated and queried. Delve is a next generation search-driven publishing tool that uses the Office Graph to surface relevant content based on a user's relationships and interactions. The Office Graph is a graph database that represents objects like documents and people as nodes and their relationships as edges. It analyzes signals across Office 365 to populate the graph and power recommendations in Delve.

7. DELVE

8. WHAT IS “DELVE”
› Delve = to delve into sth. => synonyms for: engross, search through
etc.
› Next generation Search Driven Publishing
› A really cool idea
› Based on Search, Analytics + machine learning
› A feature for O365
› Yet an other feature that’s sounds super simple but can get tricky

9. SIMPLE – NOT EASY
› My Documents
› Recent Documents
› Docs I'm following
› Documents Shared with Me
› Documents we have in common
› Suggested documents to follow (with social impact)
› Items related to current user (based on a system result source)
and now:
› Delve

10. ENABLING / DISABLING DELVE
Per User Per Tenant

12. • Content, based on your relationships with
coworkers and your behavior
• Designed to provide you with the content you
want, and the content you didn’t even know you
needed
• Delve shows you content from across your
O365 tenant
• Home – Delve curated view, containing what
delve considers to be relevant to you
• Me - find and resume content that you’ve
worked on recently.
• Delve only shows you content that you have
access to
• Boards are visible for everyone, but content is
security trimmed
OVERVIEW

13. • Documents shows up as “content cards”
on “boards” that cover information, such
as Title, Last Modified by, summary, and a
thumbnail of the document.
• New content emerges from the top,
scrolling down gives you access to more
content that Delve considers less relevant.
• Relevant content is based on your
relationships with documents and with the
people who have viewed, edited, and
created the content.
OVERVIEW

15. THE OFFICE GRAPH

16. WHAT IS A GRAPH
› http://en.wikipedia.org/wiki/Graph_(abstract_data_type)
A drawing of a labeled graph on 6
vertices and 7 edges.
A graph with
3 nodes and
3 edges
› Graphs
› Provide data abstraction
› Graph Composition
› Nodes – the data points
› Edges – the relationships
between those points

17. GRAPH DB
› NoSQL Database
› Consists of three elements:
› Nodes
› Edges
› Properties
› Every element contains a direct pointer to its
adjacent elements

18. HOW IT WORKS - EDGE
› The Office Graph contains information about
enterprise objects such as people and documents,
as well as the relationships and interactions
between these objects.
› The relationships and interactions
are represented as edges.

19. HOW IT WORKS
› Search & Analytics:
› A user is searching for “Contoso”
› 100 times per day someone is searching for
“marketing”.
› Office Graph:
› User John Doo (Actor) modified (Edge)
Contoso.docx (Object)

20. EXAMPLE - HOW A GRAPH WORKS
› Item to Item recommendation

22. GRAPH BENEFITS AND DRAWBACKS
› Benefits
› Graphs out perform SQL in topological and
locational searches, seeking out all records
that have relationships with each other
› The non reliance of a schema allows the
structure of the graph database to be changed
as new edge and node types are defined
› Drawbacks
› Data duplication. Because each
relationship is a record, many nodes can
have the same kind of relationships
› The more records that must be traversed,
the slower the query. SQL can handle large
result sets better
Database structured to capture and analyze metadata across all Office365 workloads: Exchange
Online, SharePoint Online, OneDrive for Business, Yammer etc…
The actual data is not stored, the Graph only stores metadata in the form of Nodes, and Edges.

23. HOW IT WORKS - EDGE
› Some edges represent a single interaction:
› Modified: Carl modified a document
› Viewed: Jarvis viewed a presentation
› Some edges are computed based on multiple interactions:
› WorkingWith: People whom you frequently interact with
› TrendingAround: Items that are popular in your circle of colleagues
› Some edges are relationships between enterprise objects:
› OrgManager, OrgColleague, and so on: Organizational structure edges

24. HOW IT WORKS - PRIVACY
› Public:
› object is connected to the Actor by a public edge
› visible for everyone
› can be discovered by others using Delve (with security trimming, of
course!)
› Example: "modify" or "create"
› Private:
› Object is connected to the Actor by a private edge
› cannot be discovered by other users.
› Example: "view" relationship is always private. If I view a
document, nobody will know about it.
Search ACL + Private & Public Edges

25. HOW IT WORKS - PRIVACY
› Public:
› object is connected to the Actor by a public edge
› visible for everyone
› can be discovered by others using Delve (with security trimming, of

› Example: "modify" or "create"
› Private:
› Object is connected to the Actor by a private edge
› cannot be discovered by other users.
› Example: "view" relationship is always private. If I view a
document, nobody will know about it.
Search ACL + Private & Public Edges

26. ROUNDUP - SECURITY
› All nodes contain an ACL used for security trimming
› If you do not have access to the node, it will not be included
in the result set
› Edges are classified as public or private
› Anyone with access to a node can traverse the public edge.
› Only the user that created a private edge can traverse it.

27. QUERY THE
GRAPH

28. GQL QUERIES
› Related to Me
› https://<tenant_address>/_api/search/query?Querytext='*'&a
mp;Properties='GraphQuery:ACTOR(ME)‘
› Related to Me & Someone Else
› https://<tenant_address>/_api/search/query?Querytext='*'&a
mp;Properties='GraphQuery:AND(ACTOR(ME),ACTOR(<ID>))'

29. MICROSOFT GRAPH API
› Microsoft Graph (NOT OFFICE GRAPH!!!), the single endpoint that you can use to
access a number of Microsoft's cloud technologies.
› Currently there are two insights from the Office Graph that you can
query for:
› TrendingAround: GET https://graph.microsoft.com/beta/me/trendingAround
› WorkingWith: GET https://graph.microsoft.com/beta/me/workingWith

32. POPULATING THE OFFICE GRAPH
› SharePoint content (default inclusion)
› Outlook Online attachments
› No documented «signal API»
› Use the undocumented HTTP API at own risk.
› Throttling per user

35. ARCHITECTURE
The Active Content
Cache
• Designed to enable
near-real time
updates at
conversational
speed (measured in
seconds)
• Contains most
recently active items
• Not designed to
contain the full
Tenant Graph, but
rather the most
likely to be relevant
nodes and edges.
• Every object has an
expiration policy
associated with it.
Tenant Graph Store
• The full graph of all
the nodes and
edges within a
tenant.
• Optimized for
analytics, not speed
• Indexed to
efficiently locate
nodes and used to
push nodes and
edges into the
Active Content
Cache.
• Because
optimization
decisions the
latency of moving
nodes and edges
into the Active
Content Cache
cannot be
guaranteed to be
“conversational.”

36. ARCHITECTURE
Input Router
• Directs the incoming
edits to the Active
Content Cache and
Tenant Graph Store
• Updates external
applications
regarding these
edits
• Powers the
Conversational
Experience
Workload Analytics
• Specific to each
workload, this is the
piece responsible
for reviewing local
data and updating
the Graph through
the REST API.
• Only changes to the
Active Content
Cache or to Tenant
Analytics are
pushed by the API

37. ROUNDUP - WHAT IS THE “OFFICE
GRAPH”
› Office Graph is an underling technology for Delve and a suite-wide intelligence
fabric that will help you discover content and make new connections.
› The Office Graph represents a collection of analyzed signals (edges) via
machine learning, also called insights.
› These new insights are derived from each user’s behavior, their relationships to
content, topics and one another.
› Content and signals are captured from Exchange Online, SharePoint Online,
Azure, Yammer and more coming soon…
