Dear all, I am trying to compute the cosine similarity between several documents. I have an indexed directory A made using 10000 files and another indexed directory B made using 20000 files. All the indexed documents from both directories have the same length (100 sentences). I want to get the cosine similarity between documents from directory A and documents from directory B. I have used the code from here but on the two indexed directories. So I use something like getCosineSimilarity(docs_A[i], docs_B[j]);
I get the following error: Exception in thread "main" org.apache.commons.math3.exception.DimensionMismatchException: 44,375 != 596,263 at org.apache.commons.math3.linear.RealVector.checkVectorDimensions(RealVector.java:179) at org.apache.commons.math3.linear.RealVector.checkVectorDimensions(RealVector.java:165) at org.apache.commons.math3.linear.RealVector.dotProduct(RealVector.java:307) at NewApp.testCosine.getCosineSimilarity(testCosine.java:57) Please help me. Thank you very much!
