4/15/2023 0 Comments Stem word vs word root![]() ![]() Some stemming algorithms may reduce both the words to the stem univers, which would imply both the words mean the same thing, and that is clearly wrong. Over stemming is the process where a much larger part of a word is chopped off than what is required, which in turn leads to two or more words being reduced to the same root word or stem incorrectly when they should have been reduced to two or more stem words. Let’s see more about them in the next sections. And these complications are called over stemming and under stemming. But (there’s always a but), unfortunately, it’s not as simple as that. Similarly, if we have the words - ask, asking and asked - we can apply stemming algorithms to get the root word - ask. So after we stem the words, we’ll have just the one word - send. All three words are different tenses of the same root word send. Let’s assume we have a set of words - send, sent and sending. For this post, we’ll stick to stemming and see a few examples. We’ll talk about lemmatization in another post, maybe. This is, for the most part, how stemming differs from lemmatization, which is reducing a word to its dictionary root, which is more complex and needs a very high degree of knowledge of a language. ![]() We use a few algorithms to decide how to chop a word off. This might not necessarily mean we’re reducing a word to its dictionary root. Knowing the various verb forms is a great starting point for learning these complex rules and exceptions.To put simply, stemming is the process of removing a part of a word, or reducing a word to its stem or root. However, with others, they are all different (e.g., take, I took, I had taken). Understanding the verb forms (including the root form) is essential when learning English because it allows teachers and pupils to talk about the components that form the various tenses.įor example, with some verbs, the root form, past form, and past participle form are the same (e.g., let, I let, I had let). The "-ING form" is also known as the "present participle form.".The "past form" is also known as the "past-tense form.". ![]()
