DELVE
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
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
ENABLING / DISABLING DELVE
Per User Per Tenant
• 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
• 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
THE OFFICE GRAPH
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
GRAPH DB
› NoSQL Database
› Consists of three elements:
› Nodes
› Edges
› Properties
› Every element contains a direct pointer to its adjacent elements
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.
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)
EXAMPLE - HOW A GRAPH WORKS
› Item to Item recommendation
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.
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
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
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
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.

QUERY THE
GRAPH
GQL QUERIES
› Related to Me
› https://<tenant_address>/_api/search/query?Querytext='*'&Properties='GraphQuery:ACTOR(ME)‘
› Related to Me & Someone Else
› https://<tenant_address>/_api/search/query?Querytext='*'&Properties='GraphQuery:AND(ACTOR(ME)\,ACTOR(<ID>))'
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

› Use the undocumented HTTP API at own risk.

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.”
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
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…
