1. A method of suggesting objects in a real-time collaboration tool, the method comprising: forming a first vector representing an object utilized in the real-time collaboration tool; comparing the vector to a plurality of vectors representing a plurality of objects stored in a database to locate one or more vectors similar to the first vector, the comparing including, for each vector in the plurality of vectors stored in the database, calculating a measure proportional to an inner product of the first vector and the vector from the plurality of vectors stored in the database, divided by a product of norms of each of the first vector and the vector from the plurality of vectors stored in the database; and recommending one or more of the plurality of objects stored in the database to a user of the real-time collaboration tool based on the comparing.
