Opis:: In this paper, we use non-invariant Fourier descriptors to derive transformation variables which allow us to optimally localize and reorient robot-generated maps based on the map shapes in order to determine, in an automated way, the accuracy of the generated maps. Our method uses only 4 simple calculations for alignment, therefore is extremely fast and gives a very good optimization for data maps that contain consistent, high frequency noise. A drawback to this method is occlusions in the map which affect the low frequency Fourier descriptors and cause localization and orientation errors. Preprocessing and optimization can help minimize these drawbacks. This application can be easily adapted to other areas such as image comparison or fault detection.

Tytuł:: Die typologischen Untersuchungen von Indefinitpronomina – die Implicational Map von Haspelmath
Autorzy:: Filar, Magdalena
Powiązania:: https://bibliotekanauki.pl/articles/700417.pdf

Tematy:: typology, indefinite pronouns, cross-linguistic comparison, implicational map, semantic functions
Opis:: The article is a brief introduction into the specifics and methodology of typological studies of indefinite pronouns, and presents the concept of an implicational map for indefinite pronoun functions, proposed by Haspelmath (1997). The implicational map identifies nine core functions (contexts) of indefinite pronouns that must be distinguished for the purposes of cross-linguistic comparison, and shows the semantic complexity of indefinite reference. The typological analysis conducted in this article focuses on the main similarities and differences in the form and meaning potential of indefinite pronouns, and is restricted to the three major types of Polish and German indefinite pronouns.
