Text Analytics is a branch of AI that uses NLP to create structured data by converting unstructured text from documents and databases. This data is used to power learning algorithms or for analytic purposes. Text analytics also extracts and classifies actionable insights from social media, emails, and customer feedback. What Are the Applications of Text Analytics? Text Analytics plays an indelible role in:   • Monitoring brand reputation Text analytics evaluates large data volumes from social media posts and product reviews. The real-time analysis helps businesses track and address customers’ negative feedback and uphold their brand reputation and public perception.   • Enhancing customer service Businesses use text analysis to improve their efficiency in serving their customers. The technology analyzes customer feedback and queries to reveal insights that allow organizations to promptly identify and address the issues and deliver an efficient customer experience.   • Gathering business intelligence Text analysis unravels the reasons for specific trends and patterns by assigning context to numerical data. For instance, the technology helps explain the reasons driving the change in sales performance, while data analysis only shows the change.   • Improving operational efficiency Text analytics effortlessly processes and extracts valuable information in data-intensive fields like healthcare. It decodes extensive medical records, patient feedback, and medical research papers to extract vital insights to support decision-making processes. These decisions eventually improve the operational efficiency of the institution.   • Scrutinizing incoming emails In the realm of cybersecurity, text analytics uses advanced algorithms to survey and segregate incoming emails for spam, malware, and phishing content. This process substantially minimizes the risk of cybersecurity attacks and augments overall digital security. FAQs 1. How does Text Analytics work? Text analytics processes unstructured text using NLP techniques like: Tokenization Parsing Stemming Lemmatization POS tagging Stop Word removal Text normalization These processes simplify the text into manageable units and prepare the data for machine analysis. 2. What are the major hurdles in text analytics? Text analysis may present challenges due to its lack of fixed structures and its magnitude, which often exceeds the numeric data size. Also, its unstructured nature requires more sophisticated algorithms to identify sentiments, meaning, and patterns within the diversely styled and formatted textual content. The requirements increase the processing complexities, necessitating advanced NLP techniques and ML models to draw actionable insights from text data. 3. What is the preferred language for text analytics? Generally, the preferred language for text analysis depends on the project requirements, the complexities, available tools, and the team’s expertise. Here’s a list of languages that fit the bill: Python for its libraries like Scikit-learn, NLTK, and spaCY. This language also supports NLP procedures and is simple and readable. R for data visualization and statistical analysis. 4. Are NLP and text analysis the same? Although NLP and text analysis are related, they are distinct avenues within Artificial Intelligence. NLP uses tasks like language understanding and generation and speech recognition to enable computers to interpret and generate human language. In short, NLP encompasses multiple linguistic tasks beyond text analysis. Text analysis, on the other hand, is a specific NLP-reliant application that analyzes, processes, and derives information from text data. 5. How is Text Analytics integrated into business operations? When integrating text analytics into business operations, companies must decide between developing software from scratch or adopting a ready-made SaaS solution. Also, the duration and cost of integration vary according to the scale and complexity of the process. For a successful integration, organizations should: Hire data scientists and engineers Choose the right tools Estimate the development time. Related Terms Natural Language Processing  Machine Learning  Training Data

Training-validation-testing data is a set of data fed to a machine learning model to create the model and teach it how to accurately perform a specific task. The training data consists of input data and various annotations related to the task, as extracted from multiple sources. It can be raw data in the form of images, text, or sound, with labels such as ‘bounding boxes’, tags, or connections. The machine learning algorithms use the annotations in the training data to apply the same to new, unlabeled examples. Applications of Training Data in Real-Life Situations Training data is used for Developing deep learning models for applications such as facial recognition, object detection, and gesture recognition. Creating language models for speech recognition, text classification, and sentiment analysis. Training data for autonomous vehicles to enable image and video recognition from cameras, LiDAR, and other sensors. Modeling predictive analytics for forecasting, customer segmentation, and churn prediction with historical data. Implementing models for fraud detection applications such as credit card fraud, insurance fraud, and identity theft.

Once the model has been trained using the training dataset, it is essential to test its performance with a test dataset. This dataset evaluates the performance of the model and verifies that it can generalize well with an unseen data sample. The test dataset is another subsample of the original data, often containing similar characteristics and having a proportional probability distribution to the training set. It serves as a benchmark for evaluating model performance once the training stage has been completed. Typically, the test dataset comprises 20-25% of all original data used in a Machine Learning project. At this stage, the testing accuracy can be compared to the accuracy obtained on the training set; if the accuracy of the training data is significantly greater than that of the testing data, then this indicates overfitting. As such, it is critical that the test data is representative of the original dataset and is sufficiently large enough to generate accurate predictions. What is Test Data Used For? Test data is essential for software development, as it helps ensure the software’s reliability, efficiency, and error-free operation. Banks use test data to monitor customer transactions and detect suspicious activity, such as anomalous purchases or withdrawals. Companies can leverage test data to gain insights about customers, drive product development, optimize marketing strategies and boost sales. In healthcare, test data is used to develop tests, drugs, and treatment protocols with better efficacy and to analyze patient data to recognize patterns to make informed decisions regarding patient care. Test data is also used in education to evaluate student performance, assess educational programs, generate standardized tests, and provide feedback to teachers and students on areas needing improvement.
