Webb27 apr. 2011 · For example if every 1 in 7 bases are mismatched in a pair-wise alignment, then Simrank using 7-mers would report a 0% similarity where BLAST would conclude 86% similarity. Thus, tuning k-mer length to the expected frequency of mismatches may result in application-adapted search sensitivity. Webb16 okt. 2024 · These two equations make SimRank be a state-of-art measure for similarity. However, SimRank cannot be directly applied on HINs without the ability of semantic distinguishing. Taking Fig. 1 as an example, if we compute \( s^{\prime}(p_{1} ,p_{3} ) …

Webb22 nov. 2015 · Basic SimRank Equation Let's denote the similarity between objects a and b by s (a,b) ∈ [0, 1]. Following our earlier motivation, we write a recursive equation for s (a,b). If a = b then s (a, b) is defined to be 1. Otherwise, where C is a constant between 0 and 1. A slight technicality here is that either a or b may not have any in-neighbors.
