Introduction To Text Analytics

Text analytics has recently become prominent solutions to deliver valuable business insights in a big data environment. Big data deals with three different types of data and they are unstructured, structured and semi-structured.

Textual data comes under Unstructured data and it is is different from other two types of data because it cannot be organized into numeric fields or analyzed using traditional business intelligence software. 

NLP is a necessary means to facilitate text analytics by establishing structure in unstructured text to enable further analysis. Through text mining, we take a large collection of text data and try to derive useful information by analyzing it. The text can be represented in many different ways like character, word, phrase, parts of speech, sentiment, etc... BluePi is proficient with some of the most advanced technologies including like Python, NLTK (Natural Language Toolkit), POS Tagger (Part-Of-Speech Tagger), Scala, Apache Spark’s MLlib (Machine Learning Library).

Text analytics can be processed in seven steps:

1)Text Identification

2)Text Mining

3)Text Categorization and Clustering

4)Search Access

5)Link analysis and Sentiment Analysis
