Document similarity [closed]

Question

I used tf/idf to calculate consine similarity between two documents. It has some limitation and does not perform very well.

I looked for LDA (latent dirichlet allocation) to calculate document similarity. I don't know much about this. I couldn't find much stuff too about my problem.

Can you please provide me any tutorial related to my problem? Or can you give some advices how can i achive this task with LDA???

Thanks

P.S: also is there any source code availabe to perform such task with LDA??
