Lemmatization is slower as compared to stemming but it knows the context of the word before In simple words, stemming technique only looks at the form of the word whereas lemmatization technique looks at the meaning of the word. It means after … The purpose of stemming is the same as with lemmatization: to reduce our vocabulary and dimensionality for NLP tasks and to improve speed and efficiency in information retrieval and information processing tasks. Stemming is a simpler, faster process than lemmatization, but for simpler use cases, it can have the same effect. Stemming and Lemmatization are text preprocessing methods within the field of NLP that are used to standardize text, words, and documents for further analysis. Both in stemming and in lemmatization… A lemmatization system would handle matching “car” to “cars” along with matching “car” to “automobile”. In a more traditional search engine, matching “car” to “cars” would be handled by stemming, but matching “car” to “automobile” would be handled by a separate system.

Lemmatization vs stemming. Stemming and Lemmatization in Python, follows an algorithm with steps to perform on the words which makes it faster. Main differences between stemming and lemmatization: The main difference is the way they work and therefore the result they each of them returns: Stemming algorithms work by cutting off the end or the beginning of the word, taking into account a list

Lemmatization: based on its usage, the machine looks for the appropriate dictionary form of the word. Stemming: characters are removed of the end of the word by following language-specific rules. In weak inflected languages, the method chosen may not influence the quality of the results. Stemming is a simpler, faster process than lemmatization, but for simpler use cases, it can have the same effect.

词形还原（Lemmatization）是文本预处理中的重要部分，与词干提取（stemming）很相似。简单说来，词形还原就是去掉单词的词缀，提取单词的主干部分，通常提取后的单词会是字典中的单词，不同于词干提取（stemming），提取后的单词不一定会出现在单词中。

The main difference is the way they work and therefore the result each of them returns. Stemming algorithms work by cutting off the end or the beginning of the word, taking into account a list of common prefixes and suffixes that can be found in an inflected word. This indiscriminate cutting can be successful in some occasions, but not always, and that is why we affirm that this approach presents some limitations. Stemming and Lemmatization both generate the foundation sort of the inflected words and therefore the only difference is that stem may not be an actual word whereas, lemma is an actual language word. Stemming follows an algorithm with steps to perform on the words which makes it faster. The real difference between stemming and lemmatization is threefold: Stemming reduces word-forms to (pseudo)stems, whereas lemmatization reduces the word-forms to linguistically valid lemmas.
