Revitalizing the typological approach: Some methods for finding types

Lars R. Bergman, András Vargha, Zsuzsanna Kövi
2017 Journal for Person-Oriented Research  
An artificial data set and an empirical data set were analyzed using two different methodological approaches, one more explorative (using LICUR, a cluster analysis-based procedure) and one more model-based  ...  It was also argued that, in a number of situations, a more explorative approach could be more useful than a standard model-based one.  ...  Acknowledgment The preparation of the present article was supported by the National Research, Development and Innovation Office of Hungary (Grant No. K 116965).  ...

A Graph-Based Framework for Web Document Mining [chapter]

Adam Schenker, Horst Bunke, Mark Last, Abraham Kandel
2004 Lecture Notes in Computer Science  
In this paper we describe methods of performing data mining on web documents, where the web document content is represented by graphs.  ...  We show how traditional clustering and classification methods, which usually operate on vector representations of data, can be extended to work with graph-based data.  ...  The 5-simple distance representation was an improvement in 9 out of 12 cases. Raw frequency was better in 8 of 12 cases, while normalized frequency was an improvement in 11 of 12 cases.  ...

The Noise Component in Model-based Cluster Analysis [chapter]

Christian Hennig, Pietro Coretto
2008 Studies in Classification, Data Analysis, and Knowledge Organization  
The so-called noise-component has been introduced by Banfield and Raftery (1993) to improve the robustness of cluster analysis based on the normal mixture model.  ...  The first one consists of replacing the uniform distribution by a fixed constant, modelling an improper uniform distribution that doesn't depend on the data.  ...  Banfield and Raftery (1993) introduced the term "model-based cluster analysis" for such methods.  ...
