FastText FastText Text Classification and Word Representation

Words of their herbal form can’t be used for any Machine Learning task in common. One way to use the words is to remodel these words into some representations that catch some attributes of the word. It is analogous to describing a person as – where height, weight etc are the attributes of the individual. Similarly, word representations catch some abstract attributes of words in the manner that similar words are inclined to have identical word representations. There are primarily two strategies used to develop word vectors – Skipgram and CBOW.

/fasttext – It is used to invoke the FastText library. skipgram/cbow – It is where you specify whether skipgram or cbow is for use to create the word representations. input – This is the name of the parameter which specifies here word for use as the name of the file used for education. This argument have to be used as is. data. txt – a sample text file over which we wish to train the skipgram or cbow model.

Change this name to the name of the text file you have. output – This is the name of the parameter which specifies here word for use as the name of the model being created. This argument is to be used as is. model – This is the name of the model created. As recommended by the name, text classification is tagging each document in the text with a particular class. Sentiment analysis and email type are classic examples of text class.

In this era of era, tens of millions of electronic documents are being generated day by day. It would cost a huge period of time in addition to human efforts to classify them in low-cost categories like spam and non spam, essential and unimportant etc. Text category concepts of NLP come here to our rescue. Let’s see how by doing hands on practice according to a sentiment analysis challenge. I have taken the knowledge for this evaluation from kaggle. echo “here’s a sample sentence” | .
