A Qualitative Study of Similarity Measures in Event-Based Data

2011
This paper presents an interview-based study of the definition of sequence similarity in different application areas of event-based data. The applicability of nine identified measures across these areas is investigated and discussed. The work helps highlight what are the core characteristics sought when analysing event-based data and performs a first ...

Qualitative comparison of graph-based and logic-based multi-relational data mining

Proceedings of the 4th international workshop on Multi-relational mining - MRDM '05, 2005
The goal of this paper is to generate insights about the differences between graph-based and logic-based approaches to multi-relational data mining by performing a case study of graph-based system, Subdue and the inductive logic programming system, CProgol.

The Research of Qualitative Data Hierarchical Cluster Based on Dummy Variable

2006 6th World Congress on Intelligent Control and Automation, 2006
Existing data clustering algorithms measure similarity between objects by using a distance metrics that is defined mainly for quantitative data. According to this, the idea of dummy variables in statistics is used to transform the qualitative data to measure swatch matrix shown by binary scale.

Fault Diagnosis Based on Qualitative Data by Gray System Theory

Applied Mechanics and Materials, 2014
Gray system theory is good at dealing with the uncertain problems with a little amount of data. Some equipment’s fault data is abundant, and fault phenomenon is not explicit, uncertain and qualitative. So, it is difficult to diagnosing this kind fault through the traditional methods in a short time. This paper analyzes the data’s feature and then makes

Expert diagnostic using qualitative data and rule-based inferential reasoning

1998
A diagnostic structure based on modular expert system architecture is presented in this paper. An illustrative example shows how expert knowledge is used to deduce fault situations. In this example, qualitative representation of numerical variables of process is used to interface expert knowledge and process variables.

Quantitative Risk Assessment of Noroviruses in Drinking Water Based on Qualitative Data in Japan

Environmental Science & Technology, 2006
Noroviruses are one of the major causes of viral gastroenteritis in Japan. A quantitative risk assessment was conducted to evaluate the health risk caused by this virus in drinking water. A Monte Carlo analysis was used to calculate both the probability of infection and the disease burden using disability-adjusted life years (DALYs).

Principal Component Analysis Based on a Subset of Variables for Qualitative Data

1998
A principal component analysis based on a subset of variables is proposed by Tanaka and Mori (1996) to derive principal components which are computed as linear combinations of a subset of quantitative variables but which can reproduce all the variables very well. The present paper discusses an extension of their modified principal component analysis so

Data-based revision of probability distributions in qualitative multi-attribute decision models

Intelligent Data Analysis, 2005
An automatic data-based revision method of probabilistic multi-attribute decision models is proposed. Data-based revision of decision models is defined as follows: given an existing model and a set of data items, revise the model to match the data items.

An Effective and Cost-Based Framework for a Qualitative Hybrid Data Deduplication

2019
In real world, entities may occur several times in a database. These duplicates may have varying keys and/or include errors that make deduplication a difficult task. Deduplication cannot be solved accurately using either machine-based or crowdsourcing techniques only.
