      Introduction

      Text analytics, or text mining, is all about deriving some high-quality structured data from obtained unstructured data. A very good reason for using text analytics might be extracting some additional data about customers from obtained unstructured data sources, in order to enrich that customer master data and to produce entirely new customer insight as well as to determine sentiment about different services and products. The most common text analytics applications are in case of management, for instance, healthcare patient records, and insurance claims assessments. Text analytics is widely used as well in competitor analysis, media coverage analysis, sentiment analytics, voice of the customer, pharmaceutical drug trial improvement, fault management, and different fields of service optimization.

      Text mining is the process of converting obtained unstructured data into some meaningful data notably used for further analysis, especially when it comes to measuring customer opinions, feedback, and product reviews to provide that search facility, entity modeling, and sentimental analysis in order to support mainly fact-based decision making. Text mining uses techniques from several different fields including machine learning techniques, statistical, and linguistic techniques. Text mining also involves different information particularly retrieved from unstructured data as well as the process of properly interpreting that output data in order to derive trends and patterns as well as to evaluate and interpret the output data.

      Text mining commonly involves categorization, lexical analysis, pattern recognition, annotation, clustering, tagging, visualization, information extraction, predictive analytics, and association analysis. This certain field of data analytics provides different tools, algorithm-based applications, extraction tools, and servers used for converting unstructured data into some meaningful data notably used for further analysis. The outputs of such data analytics are some extracted entities and facts particularly with certain relationships stored in some relational XML or some other
