I have spark job to compute the similarity between text documents:
RowMatrix rowMatrix =newRowMatrix(vectorsRDD.rdd());CoordinateMatrix rowsimilarity=rowMatrix.columnSimilarities(0.5);JavaRDD<MatrixEntry> entries = rowsimilarity.entries().toJavaRDD();List<MatrixEntry> list = entries.collect();for(MatrixEntry s : list)System.out.println(s);
the MatrixEntry(i, j, value) represents the similarity between columns(let's say the features of documents).But how can I show the similarity between rows? suppose I have five documents Doc1,.... Doc5, I would like to show the similarity between all those documnts. How do I get that?
