Text Analytics in Tableau: Unlocking Insights from Your Data
Introduction
Text data is ubiquitous.
From social media posts to customer reviews, product descriptions to support tickets, a vast ocean of unstructured textual information surrounds us.
Harnessing the power of this data requires a specialized approach—and that’s where text analytics in Tableau shines.
This article delves into the world of text analytics in Tableau, guiding you through the process of extracting meaning, uncovering hidden patterns, and transforming raw text into actionable business insights.
This exploration will emphasize how text analytics in Tableau can unlock the value within textual datasets.
Understanding the Basics of Text Analytics in Tableau
What is Text Analytics?
Text analytics in Tableau goes beyond simple keyword searches.
It involves using algorithms and techniques to identify meaningful patterns, sentiments, and relationships within unstructured textual data.
From sentiment analysis to topic modeling, these methods transform raw words into valuable insights for various use cases.
Effectively applying text analytics in Tableau hinges on the correct combination of techniques and tools.
This is how text analytics in Tableau allows data-driven decision-making.
How Tableau Handles Text Data
Tableau’s native functionality is excellent for visualizing numerical and categorical data.
But what about text data?
The core power of text analytics in Tableau often comes from using Tableau’s excellent integration with external data and preparation capabilities (and frequently combined with custom calculated fields or the use of custom data wrangling to get the needed data ready) .
Tableau connects to databases housing textual information or readily processes downloaded data, making this type of work possible for different text analytic approaches.
Preparing Text Data for Tableau
Data Collection and Organization
Collecting relevant textual data and properly organizing it into a structured format is the foundation of successful text analytics in Tableau.
Ensure consistency in your data (same type of data entries; no errors etc.).
Often, data preparation is the most laborious and important task within any analysis process.
Text Preprocessing: Cleaning the Data
Before applying any advanced analytics in Tableau to this data, ensure the data is prepared properly, removing irrelevant characters (e.g. hashtags).
Stop words, typos and redundant information also must be removed or appropriately flagged in order to improve the accuracy of sentiment analysis using text analytics in Tableau.
Text analytics in Tableau works optimally with clean, accurate text.
Text analytics in Tableau uses proper preprocessing in order to correctly handle raw data.
Stop word removal, for instance, plays a significant role in effectively applying sentiment analysis, another powerful feature of text analytics in Tableau.
Performing Text Analytics with Tableau
Using Natural Language Processing (NLP) Libraries
Tableau doesn’t offer NLP inbuilt.
Usually, the way to use advanced features from NLP in text analytics in Tableau will depend upon the ability of external data preparation and input or custom functions or workflows.
We’ll show common ways to execute basic to sophisticated processes that integrate external processes for using the analytical processes.
Some external libraries can significantly improve the quality and comprehensiveness of any output based on the quality and thoroughness of any inputs made.
External processing (using an alternative environment, such as Python) provides greater functionality.
Extracting Key Topics and Trends
Topic modeling is an important application of text analytics in Tableau.
Techniques allow finding recurring patterns and groups of words within text collections that signify trends and topics.
For example, finding how frequently the topic of “customer satisfaction” appears, or the words and phrases frequently mentioned by customers within product descriptions, feedback forums or social media.
Often text analytics in Tableau can be enhanced by combining with methods or programs like LDA or similar techniques to reveal the key words and underlying themes driving any discussions, behaviors or outputs that exist within datasets of textual information.
Using text analytics in Tableau in this way can identify useful indicators and insightful results from text input from diverse groups and collections.
Implementing Sentiment Analysis in Tableau
Measuring Customer Feedback
Applying text analytics in Tableau to identify sentiment within feedback or reviews helps quantify how satisfied customers are with specific products.
Customer satisfaction is one of the main things that is measured.
Positive, neutral or negative sentiment from customers, can often tell us something about products and services within a given domain.
Visualizing Sentiment Trends
Tableau enables effective visualization of sentiment data, highlighting shifts in public opinion.
Creating charts, from sentiment ratings on social media, review scores across time periods (i.e. customer feedback collected in different times of the year), can be valuable.
Advanced Text Analytics in Tableau: Beyond Basics
Visualizing Relationships Between Words
You can even take analysis of words and their meanings and relationships further than simple counts and frequency analysis; visualize the semantic relationships (word networks/co-occurrences etc.).
How similar to certain words or themes are certain products (often used for comparisons to assist understanding of which categories of products align closely with similar meanings).
For more powerful analysis text analytics in tableau has the ability to be significantly improved in order to allow this greater insight.
Exploring Text Clusters with Word Clouds
Another text analytics in Tableau method: generate meaningful word clouds or highlight areas where several concepts come together (i.e., product topics grouped in collections with certain trends).
Text analytics in Tableau can improve quality of work from visual methods alone
How To Integrate Text Data Into Your Tableau Workflows
Using External Data Sources
Integrate a database containing the textual information in your analysis pipeline from your text data source.
Often, the analysis that uses the external information should already contain a collection of steps and routines that must be preformed prior to analysis of this information to maintain the quality.
Using text analytics in Tableau often comes together with various other datasets or external routines, especially since data frequently arrives in multiple formats
Building Calculated Fields for Analysis
Use calculated fields for sophisticated explorations by identifying meaningful metrics.
Create metrics to evaluate positive sentiment percentages of your review collections.
Understanding sentiment through metrics provides clarity for insight creation and decision making.
Leveraging Data Blending for Combining Data Sources
Combine relevant, non-text, numerical or quantitative information together.
Combining customer reviews (text) and demographics or product information for more thorough insights about product effectiveness.
Effectively analyzing trends through data analytics from combining diverse text and other datasets can improve analysis in multiple categories.
Conclusion: The Power of Text Analytics in Tableau
Text analytics in Tableau is a valuable tool.
By integrating these analytical techniques (both simple and advanced ones), you can transform unstructured text into structured data—providing your organization with insightful understanding to help support data-driven decisions.
Text analytics in Tableau enables business insight identification for your business from a powerful combination of processes.
Effectively harnessing textual data within tableau unlocks actionable insights to understand consumer behavior patterns and ultimately support crucial decisions based on thorough knowledge of consumer needs, wants and requirements from various products or services in an enterprise, organization or within an ecosystem or segment.
Using text analytics in Tableau will continue to be one of the main methods to interpret meaningful results within your data.
