This training course is an introduction into knowledge discovery from unstructured data like text documents. It focuses on the necessary preprocessing steps and the most successful methods for automatic text classification (including Naive Bayes and Support Vector Machines, SVM) and text clustering. Many practical exercises for different settings (for example e-mail spam detection, automatical e-mail routing, adaptive personal news filtering, sentiment analysis of text documents like news, web pages, blogs, e-mail, or PDF documents) will enable the participants to transfer the gained knowledge to own text mining problems.
After the training course the participants will have the ability to
- identify the processes for processing unstructured data,
- transform textual data into a structured format,
- apply different statistical text processing methods,
- perform text classification or text clustering,
- work on recent tasks like sentiment analysis or opinion mining.
This training course together with the course “Data Mining / Predictive Analytics with RapidMiner and RapidAnalytics 3” is the recommended preparation for the exam for becoming a certified Rapid-I Expert.
