Nov 11, 2020 · Lemmatization. Lemmatization also reduces the word to its root just like Stemming. Lemmatization is closely related to stemming. The difference is that a stemmer operates on a single word without knowledge of the context, and therefore cannot discriminate between words which have different meanings depending on part of speech.

- Lemmatization is the process of converting a word to its base form. Python has nice implementations through the NLTK, TextBlob, Pattern, spaCy and Stanford CoreNLP packages. We will see how to optimally implement and compare the outputs from these packages.
- Stemming and Lemmatization are both data pre-processing steps. However, they both work to establish that the two given words are the different forms of the same word, the approach the two follow is absolutely different. Stemming - It follows a heuristic approach and works by cutting out the prefix or the suffix to find the stem.

Natural language processing (NLP) is a subfield of linguistics, computer science, and artificial intelligence concerned with the interactions between computers and human language, in particular how to program computers to process and analyze large amounts of natural language data. This annotator analyzes every word in a sentence and assigns it to a head node (another word in the same sentence) with a syntactic relation. The labels given to each relation of head and dependent reflect syntactic relations that exist between those words; for example, if a verb has a noun phrase as a subject, the relation of the verb to the head noun of its subject is given the label nsubj.
