Fabric quality and performance is assessed subjectively by the customer using an important and complex phenomenon of fabric hand. Objectively, it is evaluated with complicated and expensive instruments, such as Kawabata Evaluation System for Fabrics (KES-F) and Fabric Assurance with Simple Testing (FAST). The present research explores a non-touch objective approach, i.e., three-dimensional (3D) drape model to estimate fabric hand. Fabric hand prediction was testified on different commercial fabrics spanning a wide range of areal weight, thickness, yarn count, and fabric density. Fabric objective ranks based on drape indicators using principal component analysis (PCA) were compared with subjective ranks of fabric hand. Additionally, fabric drape is evaluated three dimensionally and a new drape indicator drape height (DH) is proposed. The cosine similarity results have proved fabric drape as an objective alternate to fabric hand.

The main goal of this paper is to analyse intelligent text string matching methods (like fuzzy sets and relations) and evaluate their usefulness for image search. The present study examines the ability of different algorithms to handle multi-word and multi-sentence queries. Eight different similarity measures (N-gram, Levenshtein distance, Jaro coefficient, Dice coefficient, Overlap coefficient, Euclidean distance, Cosine similarity and Jaccard similarity) are employed to analyse the algorithms in terms of time complexity and accuracy of results. The outcomes are used to develop a hierarchy of methods, illustrating their usefulness to image search. The search response time increases significantly in the case of data sets containing several thousand images. The findings indicate that the analysed algorithms do not fulfil the response-time requirements of professional applications. Due to its limitations, the proposed system should be considered only as an illustration of a novel solution with further development perspectives. The use of Polish as the language of experiments affects the accuracy of measures. This limitation seems to be easy to overcome in the case of languages with simpler grammar rules (e.g. English).

Przepływ informacji, który jest w dzisiejszych czasach niezbędny do działania organizacji na rynku wspomagany powinien być technikami informatycznymi. Wiedza, która jest konieczna do pozyskania na rynku logistyki jest pochodną danych i informacji, którymi dysponuje przedsiębiorstwo logistyczne. Niezbędne jest szybkie zbieranie danych, gromadzenie ich oraz przetwarzanie i analiza nie tylko wewnątrz firmy ale również czerpanie wiedzy z zewnątrz. Pomocne w tym zakresie mogą okazać się metody bazujące na eksploracyjnej analizie danych tekstowych – text mining. Zaprezentowano możliwe przykłady wykorzystania i korzyści płynące z zastosowania metod text miningowych w logistyce. W artykule przedstawiono zagadnienie grupowania towarów/produktów, jako atrybutów, według których dokonuje się porównywania, oceny i grupowania kontrahentów. Dokonano zarówno przeglądu jak i przedstawiono propozycje metod i algorytmów grupowania w katalogu towarów.

Necessary the flow of the information which is in contemporary times to the working of the organization should be helped computer technicians. The knowledge which is essential to gaining over on the field of the logistics is the derivative data and information which the logistic company disposes. He indispensable is fast data setting, collection their and processing and analysis not only inside the firm but also draws knowledge from outside. Helpful in this field can prove methods of the text mining. Introduced the possible examples of exploitation and advantages flowing from the use of methods text mining in the logistics. In the paper introduced the question of clustering goods/ products as the attributes according to which achieved comparing, estimation and clustering contractors. It was achieved both the inspection as and the introduced proposals of methods and the algorithms of clustering in the catalog of goods.
