The first version of Delve formerly known as “Project Olso & Office Graph” is now available.
So what exactly is Delve? Here is what Microsoft says:
Delve (Codename Oslo) & Office Graph
Delve (Codename Oslo) is the first experience to use the power of the Office Graph. Delve is a new way to search and discover content across Office 365 based on personalized insights. Delve will be available as a Windows 8 app, on mobile devices, and integrated in the Office 365 web experience. Office Graph is an underlying technology and a suite-wide intelligence fabric that will help you discover content and make new connections. The Office Graph analyzes signals and applies machine learning. Personalized insights are built up for each user, based on their behavior, their relationships to content, topics and one another. Content and signals are captured from Exchange Online, SharePoint Online, and Yammer.
The Delve feature is located in the Office Bar at the top of the O365 site. Delve is only available for O365.
Here are some additional useful links:
Actually Delve shows content from SharePoint team site and OneDrive for business content. In the future we will also see more content sources to push content to the Office Graph, such as email attachments, meetings, group content, video portal content, yammer signals/shares etc. We will also see a API for Delve in the future. The API will probably be a REST based API supporting CRUD operations.
Actually Delve looks like this:
Going to Query Editor in a search result webpart we can see a new Result Source:
This result source is not shown under SharePoint online administration or in the site settings menu. It’s actually only visible in the Query Builder. The Office Graph gets its own index. We can assume that this new result source is mapped to the new Graph Index. Actually the new result source is not showing any results using it in a search result webpart.
Is Delve only another content aggregation?
In SharePoint / SharePoint Online we have several sites and webparts showing content based on search and social indicators:
· My Documents
· Recent Documents
· Docs I'm following
· Suggested documents to follow
· Documents Shared with Me
· Documents we have in common
Aggregating all this in one page shows that the content is mostly related:
So is Delve only a aggregated view of all this? No it is not! Delve is based on the Office Graph which is a kind of machine learning to map the relationships between people, content, and activity that occurs across Office 365
To give you an idea how this works let’s have a look at the following example.
As part of Google we have an Analytics engine called Google Trends. http://www.google.com/trends/
I use this engine to get the following report.
• Search term 1: Hangover
• Search term 2: Vodka
• Entity: Time
That means: Item1=Hangover Item2=Vodka
Item to Item recommendation shows a correlation between this to search terms / items at the end of December every year – at New Year's Eve ;-)
To complete this lets have a look on how the features like Items “Related to Current User” or “Suggested documents to follow” works.
“Items related to current user” is based on a result source. This result source can be used in content search webpart:
“Suggested documents to follow” is based on the managed property “recomendetfor”
Based on search:
• 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)
Based on search and the Office Graph
This all can be a little bit confusing for end users and decision maker. I think that Delve is the future of all this ideas and techniques. Delve will get an addition push with the upcoming Phone and Windows Apps which allows us to get access to all this using mobile devices and without using the web interface of O365.
