How Can Sentiment Analysis be Used?

Sentiment Analysis finds a variety of applications within an organization to understand the voice of customers and employees. It plays a significant role for any business or organization. It helps data analysts within large enterprises gauge public opinion, conduct nuanced market research, monitor brand and product reputation, and understand customer experiences.


What are the steps of Sentiment Analysis?

Sentiment Analysis steps is complex that consist of 5 different procedures to analyze sentiment data. These steps are:


1. Data collection: The first step of sentiment analysis consists of collecting data from user-generated content in blogs, forums, and social networks. These data are disorganized and expressed differently by using various vocabularies, slang, writing context, etc. Manual analysis is almost impossible. Therefore, text analytics and natural language processing are used to extract and classify such data.


2. Text preparation: It consists of cleaning the extracted data before analysis. The Non-textual contents that are irrelevant for the analysis are identified and eliminated;


3. Sentiment detection: The extracted sentences of the reviews and opinions are analyzed. The sentences with subjective expressions (opinions, beliefs, and views) are retained, and sentences with objective communication (facts, factual information) are discarded;


4. Sentiment classification: In this step, subjective sentences are classified in positive, negative, good, bad; like-dislike, but classification can be made by using multiple points;


5. Presentation of output: The main objective of sentiment analysis is to convert unstructured text into meaningful information. When the analysis is finished, the results are displayed on graphs like pie charts, bar charts, and line graphs. Moreover, time can also be analyzed and graphically displayed, constructing a sentiment timeline with the chosen value (frequency, percentages, and averages) over time.

what is topic modelling

  Have you ever been in a situation where you were asked to find a specific piece of information for your company, from an extensive collection of documents, within a tight deadline? When you are looking through the company database manually for a crucial piece of information, it is highly time-consuming and practically impossible. With the growing amount of data in recent years, it is difficult to obtain the relevant and desired information in a short period, especially during urgent matters. In such cases, we can use  Topic Modeling  to mine through the data and fetch the information we are looking for quickly. It automatically identifies topics present in a text object and derives hidden patterns exhibited by a text corpus. Thus, assisting better decision making. A good topic model should result in the following– “health”, “doctor”, “patient”, “hospital” for a topic such as “Healthcare”. For a business that deals with thousands of customer interactions daily, such as social media, c

Why topic modeling?

  As large amounts of data are collected every day, more and more information becomes available. At the same time, it becomes difficult to access the necessary information that we are looking for. Moreover, as these kinds of data are unstructured or free-form text, analyzing such volumes of text data manually becomes highly tedious and time-consuming. The simple solution is to use Topic modeling , as it provides us with methods for automatically organizing, understanding, searching, and summarising extensive electronic archives. It can help us sort through unstructured data in the following ways: - Discovering the hidden themes in the collection. - Classifying the documents into the discovered themes. - Using the classification to organize/summarise/search the documents. With the use of Topic Modeling , we can figure out what topics a bunch of unstructured text cover. This set of text documents may range from emails to survey responses, support tickets, product reviews, etc. Once we id

                              Sentiment analysis means contextual data mining wherein you input a sentence, and it is categorized according to the underlying consumer emotions. A sentiment analysis system for text analysis combines natural language processing (NLP) and machine learning techniques to assign weighted sentiment scores to the entities, topics, themes, and categories within a sentence or phrase. When we look at any sentence, the human brain searches for sentiment-bearing phrases – that is, words and phrases that carry a tone or opinion and tries to interpret it, usually as adjective-noun combinations. We also draw from our previous experiences and accumulated knowledge to identify each sentiment-bearing phrase and interpret their negativity or positivity. This is precisely how computer sentiment analysis works. It involves deep learning and machine learning techniques that “trains” the system to instinctively recognize nouns and phrases as “offensive” and categorize them a
