Porter algorithm is the least aggressive algorithm which is why is widely used and is the oldest stemming algorithm. The stems of the words are somewhat intuitive and are understandable. On the other hand, Lancaster algorithm is very aggressive because of its strictly chopping words and making it much confusing. With this algorithm in use, the stems become non-relatable to some extent and for this very reason, it is least used.
