We based our research on the Innovativeness Union Scoreboard (IUS) dataset. In order to solve the problem, we propose to use the Double Self-Organizing Feature Map (SOM) approach. In the first step, countries, described by determinants of innovativeness economy, are clustered using SOMs according to five year time series for each determinant separately. In the second step, results of the first step are clustered again using SOM to obtain the final correlation represented in the form of a minimal spanning tree. We propose some modifications of the clustering process using SOMs to improve classification results and efficiency of the learning process.<\/jats:p>","DOI":"10.3233\/fi-2014-959","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T00:43:01Z","timestamp":1575333781000},"page":"37-48","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Towards Assessment of Innovativeness Economy Determinant Correlation: the Double Self-Organizing Feature Map Approach"],"prefix":"10.1177","volume":"129","author":[{"given":"Marta","family":"Czy\u017cewska","sequence":"first","affiliation":[{"name":"University of Information Technology and Management, Sucharskiego Str. 2, 35-225 Rzesz\u00f3w, Poland. mczyzewska@wsiz.rzeszow.pl, jszkola@wsiz.rzeszow.pl, kpancerz@wsiz.rzeszow.pl"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jaros\u0142aw","family":"Szko\u0142a","sequence":"additional","affiliation":[{"name":"University of Information Technology and Management, Sucharskiego Str. 2, 35-225 Rzesz\u00f3w, Poland. mczyzewska@wsiz.rzeszow.pl, jszkola@wsiz.rzeszow.pl, kpancerz@wsiz.rzeszow.pl"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Krzysztof","family":"Pancerz","sequence":"additional","affiliation":[{"name":"University of Information Technology and Management, Sucharskiego Str. 2, 35-225 Rzesz\u00f3w, Poland. mczyzewska@wsiz.rzeszow.pl, jszkola@wsiz.rzeszow.pl, kpancerz@wsiz.rzeszow.pl"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,1,1]]},"container-title":["Fundamenta Informaticae"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2014-959","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2014-959","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T06:30:56Z","timestamp":1777444256000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/FI-2014-959"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,1]]},"references-count":0,"journal-issue":{"issue":"1-2","published-print":{"date-parts":[[2014,1]]}},"alternative-id":["10.3233\/FI-2014-959"],"URL":"https:\/\/doi.org\/10.3233\/fi-2014-959","relation":{},"ISSN":["0169-2968","1875-8681"],"issn-type":[{"value":"0169-2968","type":"print"},{"value":"1875-8681","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,1]]}}}
