An Implementation of TF-IDF in C++

• Need to modify the function loadData() to fit the real situation.
• Two versions of outputs

• Eigen::MatrixXf object.
• std::vector<std::vector<double>> object.

Use TF-IDF in music lyric similarity calculation.

• Both single thread and multi thread versions.
• Compile with g++ for single thread version

g++ -std=c++0x -Wall -o lyricSimilarity lyricSimilarity.cpp -static-libstdc++

• Compile the multithreading version

g++ -std=c++0x -Wall -o lyricSimilarity_multithreading lyricSimilarity_multithreading.cpp -static-libstdc++ -lpthread
