“…The Wrocław taxonomy is one of the oldest and most widely used hierarchical clustering methods (Pedich, 1977;Mercik, Kołodziejczyk;1986, Senetra andSzarek-Iwaniuk, 2019). Its results are greatly influenced by the selection of the features of the objects which are compared and the critical distance used.…”

Classification of the Tatra Mountain lakes in terms of the duration of their ice cover (Poland and Slovakia)

2019

This paper presents the results of a classification of the Tatra lakes based on the duration of their ice cover, altitude, volume, and potential incoming solar radiation (PISR). It is embedded in the context of the impact of current climate change on the mountain environment. A digital elevation model, morphometric data, satellite imagery from the winter seasons of 2015-2017 and the Wrocław taxonomy method were used in the study. It was found that the order of freezing and thawing of the lakes investigated may change from year to year. The relationship between ice cover duration and altitude is clearly weakened by variations in lake volumes, with insolation having a noticeably lesser effect. Determining the duration of ice cover of the lakes over several seasons facilitates identifying the similarities and dissimilarities between them. Five groups of lakes displaying similar characteristics were identified as well as 2 groups of lakes with highly individual characteristics. Based on the data obtained, it can be concluded that the duration of ice cover on the Tatra lakes has been shortening noticeably over the last 100 years. Small high-altitude lakes seem to be most vulnerable to climate change.

“…The cluster analysis method employed allows the lakes to be grouped objectively with no need to first assume the number of classes. In addition, the boundaries between the classes distinguished are measurable and the structure of the similarities between the objects researched is conspicuous (Senetra and Szarek-Iwaniuk, 2019).…”

“…This method was developed by Hwang and Yoon (Hwang and Yoon 1981) and further improvement was made by Hwang (Hwang et al 1993). Hwang and Yoon proposed clustering, which is derived as an enhancement of the Wroclaw Taxonomy, which in turn is derived from the prior works of (Senetra and Szarek-Iwaniuk 2019;Czekanowski 1961 Lu and White 2014). The entropy weight TOPSIS method is a combination of the entropy method and TOPSIS method, in which the specific steps are as follows.…”

This paper presents an evaluation index system of public service quality, which contains 35 indexes from the dimensions of the output and effect. Based on data from 2010 to 2017 in 12 coastal provinces and cities of China, this paper assesses public service quality by using the methods of entropy weight order preference similarity to the ideal solution (TOPSIS) and analyzes the effect of fiscal transparency on public service quality. The results show that the public service quality in the 12 coastal provinces and cities of China studied is relatively high, and fiscal transparency has a positive effect on public service quality. This analysis showed that an increase of 1% in fiscal transparency would lead to an increase of 0.0323% in the quality of public services. Fiscal transparency contributes to the quality of public services by improving the scale of investment and the efficiency of public services expenditure; this is because fiscal transparency can increase the expenditure on public welfare services and curb official corruption. Furthermore, the proposed evaluation index can enable government administrators to take the necessary steps on the appropriate dimensions to improve public service quality. This study can provide some guidelines for other countries, especially to improve public service quality by increasing fiscal transparency.

“…According to Zavadskas et al (2010), the major problem here is the "estimation influence of different attributes". To solve this problem, both practitioners and scientists apply either qualitative or quantitative methods (Barańska, 2008;Maleta, 2013;Senetra & Szarek-Iwaniuk, 2019). From the valuation procedural prospective, the attribute significance (which is called the attribute weight) represents the impact of a feature on the price range in the real estate market (Sawiłow, 2004).…”

One of the largest problems in the real estate market analysis, which includes valuation, is determining the significance of individual property attributes that may affect value or attractiveness perception. The study attempts to assess the significance of selected attributes of real estate based on the detection and analysis of the emotions of potential investors. Human facial expression is a carrier of information that can be recorded and interpreted effectively via the use of artificial intelligence methods, machine learning and computer vision. The development of a reliable algorithm requires, in this case, the identification and investigation of factors that may affect the final solution of the problem, from behavioural aspects through technological possibilities. In the presented experiment, an approach that correlates the emotional states of buyers with the visualization of selected attributes of properties is utilized. The objective of this study is to develop an original method for assessing the significance of property attributes based on emotion recognition technology as an alternative to the commonly used methods in the real estate analysis and valuation, which are usually based on surveys. The empirical analysis enabled determination of the mainstream property attributes significance from evoked emotions intensity within the group of property clients (represented by 156 respondents). The significance ranking determined on the basis of the unconscious expressed facial emotions was verified and compared to the answers given in a form of questionnaire. The results have shown that the conscious declaration of the attribute ranking differs from the emotion detection conclusions in several cases.
