چکیده

Providing means for effectively accessing and exploring large textual data sets is a problem attracting the attention of text mining and information visualization experts alike. The rapid growth of the data volume and heterogeneity, as well as the richness of metadata and the dynamic nature of text repositories, add to the complexity of the task. This chapter provides an overview of data visualization methods for gaining insight into large, heterogeneous, dynamic textual data sets. We argue that visual analysis, in combination with automatic knowledge discovery methods, provides several advantages. Besides introducing human knowledge and visual pattern recognition into the analytical process, it provides the possibility to improve the performance of automatic methods through user feedback.

Knowledge Discovery from Texts with Conceptual Graphs and FCA

Building conceptual lattices from conceptual graphs looks as natural way in Formal Concept Analysis but still is not discovered at length. If conceptual graphs are acquired from natural language texts then they contain specific material for knowledge discovery. Conceptual graphs serve as semantic models of text sentences and the data source for concept lattice. With the use of concept lattice i...
