An Efficient Parallelized Ontology Network-Based Semantic Similarity Measure for Big Biomedical Document Clustering

Algorithm 1

Algorithm of MapReduce-based data transformation.

Data transformation

Input: <d, list(m)>

Output: <m, list(d)>

Notation: Write (k, v) outputs <k, v>

Class mapper

 Method map (d, list(m))

  For each m ∈ list(m)

   Write (m, d)

  End for

Class reducer

 Method reduce (m, list(d))

   s ← string(list(d))

   Write (m, s)
