Sentence Segmentation or Sentence Tokenization is the process of identifying different sentences among group of words. Spacy library designed for Natural Language Processing, perform the sentence segmentation with much higher accuracy. Spacy provides different models for different languages. In this post we’ll learn how sentence segmentation works, and how to set user defined segmentation rules.
Named Entity Recognition NER works by locating and identifying the named entities present in unstructured text into the standard categories such as person names, locations, organizations, time expressions, quantities, monetary values, percentage, codes etc. Spacy comes with an extremely fast statistical entity recognition system that assigns labels to contiguous spans of tokens.
Parts of Speech tagging is the next step of the tokenization. Once we have done tokenization, spaCy can parse and tag a given Doc. spaCy is pre-trained using statistical modelling. This model consists of binary data and is trained on enough examples to make predictions that generalize across the language. Example, a word following “the” in English is most likely a noun.
spaCy is designed specifically for production use. It helps you build applications that process and “understand” large volumes of text. It can be used to build information extraction or natural language understanding systems, or to pre-process text for deep learning. In this article you will learn about Tokenization, Lemmatization, Stop Words and Phrase Matching operations using spaCy.
spaCy is an open-source Python library that parses and “understands” large volumes of text.
spaCy is the best way to prepare text for deep learning.
It interoperates seamlessly with TensorFlow, PyTorch, scikit-learn, Gensim and the rest of Python’s awesome AI ecosystem.
With spaCy, you can easily construct linguistically sophisticated statistical models for a variety of NLP problems.
It does not matter how much experience you have, actually anybody can start or switch to data science and machine learning. The only important this is, how much eager you are for it. What it means to you. If you are very much keen to work in this field then nobody can stop you. There might be some short term hurdles however if you are focused enough and know your goals regarding where you want to see yourself after certain years, then you will definitely be successful in overcoming those hurdles.
Lot of research is being done in medical field, where researchers are working to develop AI models which can even develop the “Sense of smell”.It will help medical field to detect illness by smelling the human’s breath.They have achieved great success in detecting chemicals called aldehydes. Aldehydes are associated with human illnesses and stress.
NLP can organize unstructured data and perform several automated tasks such as automatic summarization, sentiments analysis, speech recognition, etc.
