Visualizing the document pre-processing effects in text mining process
(2018-01-01)
Text mining is an important step to categorize textual data by using data mining techniques. As most obtained textual data is unstructured, it needs to be processed before applying mining algorithms – that process is known ...
HiPP: A Novel Hierarchical Point Placement Strategy and its Application to the Exploration of Document Collections
(IEEE COMPUTER SOC, 2008)
Point placement strategies aim at mapping data points represented in higher dimensions to bi-dimensional spaces and are frequently used to visualize relationships amongst data instances. They have been valuable tools for ...
Least square projection: A fast high-precision multidimensional projection technique and its application to document mapping
(IEEE COMPUTER SOC, 2008)
The problem of projecting multidimensional data into lower dimensions has been pursued by many researchers due to its potential application to data analyses of various kinds. This paper presents a novel multidimensional ...
Hybrid visualization approach to show documents similarity and content in a single view
(2018-05-23)
Multidimensional projection techniques can be employed to project datasets from a higher to a lower dimensional space (e.g., 2D space). These techniques can be used to present the relationships of dataset instances based ...
Learning principles in program visualizations: a systematic literature review
(2016-10)
Program visualizations help students understand
the runtime behavior of other programs. They are educational
tools to complement lectures or replace inefficient static
drawings. A recent survey found 46 program ...
