Line 18: [[Image:vector space model.jpg\|right\|250px]] [[Relevance (information retrieval)\|Relevance]] [[ranking]]s of documents in a keyword search can be calculated, using the assumptions of [[semantic similarity\|document similarities]] theory, by comparing the deviation of angles between each document vector and the original query vector where the query is represented as ~~the~~a ~~same~~vector ~~kind~~with ofsame ~~vector~~dimension as the vectors that represent the other documents. In practice, it is easier to calculate the [[cosine]] of the angle between the vectors, instead of the angle itself:
