Text Link Analyisis node (SPSS Modeler)
Sometimes, you might not need to create a category model to score. The Text Link Analysis (TLA) node adds a pattern-matching technology to text mining's concept extraction. TLA identifies relationships between the concepts in the text data based on known patterns. These relationships can describe how a customer feels about a product, which companies are doing business together, or even the relationships between genes or pharmaceutical agents.
