1. A method comprising: detecting, by a processor, a user interaction with a first collaboration tool of a multi-model collaboration space, wherein the user interaction comprises at least one of engaging in a collaboration activity associated with the first collaboration tool or accessing a first item of content in the first collaboration tool; in response to the user interaction, identifying, by the processor, a second item of content from a second collaboration tool of the multi-model collaboration space, wherein the second item of content is contextually related to at least one of the collaboration activity or the first item of content in the first collaboration tool; and generating, by the processor, a unified content view of the multi-model collaboration space automatically in response to the user interaction, the unified content view comprising a first interactive interface of the first collaboration tool and a second interactive interface of the second collaboration tool, the second interactive interface presenting the second item of content associated with the second collaboration tool, wherein the second interactive interface integrates a functionality of the second collaboration tool such that a user can establish in an electronic collaborative activity directly via the second interactive interface, wherein the first interactive interface and the second interactive interface are separately arranged from each other in the unified content view, wherein the unified content view of the multi-model collaboration space is also visually represented in three dimensions, the three dimensions comprising a resource dimension, a time dimension, and a semantic dimension, and wherein the three dimensional unified content view of the multi-model collaboration space is nested to comprise a second three dimensional multi-modal collaboration space.
