Opis:
This paper introduces my concept of cognitive equivalence (cf. Mandelblit, 1997), an attempt to reconcile elements of Nida’s dynamic equivalence with recent innovations in cognitive linguistics and cognitive psychology, and building on the current focus on translators’ mental processes in translation studies (see e.g. Göpferich et al., 2009, Lewandowska-Tomaszczyk, 2010). My approach shares its general impetus with Lewandowska-Tomaszczyk’s concept of re-conceptualization, but is independently derived from findings in cognitive linguistics and simulation theory (see e.g. Langacker, 2008; Feldman, 2006; Barsalou, 1999; Zwaan, 2004). Against this background, I propose a model of translation processing focused on the internal simulation of reader reception and the calibration of these simulations to achieve similarity between ST and TT impact. The concept of cognitive equivalence is exemplarily tested by exploring a conceptual / lexical field (MALE BALDNESS) through the way that English, German and Japanese lexical items in this field are linked to matching visual-conceptual representations by native speaker informants. The visual data gathered via this empirical method can be used to effectively triangulate the linguistic items involved, enabling an extra-linguistic comparison across languages. Results show that there is a reassuring level of inter-informant agreement within languages, but that the conceptual domain for BALDNESS is linguistically structured in systematically different ways across languages. The findings are interpreted as strengthening the call for a cognition-focused, embodied approach to translation.

Opis:
Small earth dams are most valuable in arid and semi-arid areas where they are used for both domestic and agricultural purposes. These dams however, continue to fail. The causes of such failures are interconnected in the sense that one can trigger the other. Most research into earth dams nevertheless, uses reductionist approaches. Such approaches do not consider the complex interactions between these modes and/or causes. This research used fuzzy cognitive mapping to identify the prominent modes and causes of small earth dam failure in Swaziland and to capture their interactions. A sample of seven earth dam construction experts was purposively selected from five institutions for individual interviews. An individual map was developed from each interview. An aggregated map was thereafter developed by combining seven individual maps. The results indicated that overtopping, piping and sliding were the common modes of earth dam failure. Overtopping was mainly due to siltation whilst animal barrows and tree roots were largely responsible for piping. Sliding was mostly associated construction defects and sudden drawdown. It was concluded that most of the failures were linked to poor management of catchments and that of the dams. It is recommended that future designs and management should increase the level of community participation in order to limit some of the causes associated with land use practices.

Opis:
In this review-paper, I focus on biopsychological foundations of geometric cognition. Starting from the Kant’s views on mathematics, I attempt to show that contemporary cognitive scientists, alike the famous philosopher, recognize mutual relationships of visuospatial processing and geometric cognition. What I defend is a claim that Tinbergen’s explanatory questions are the most fruitful tool for explaining our “hardwired,” and thus shared with other animals, Euclidean intuitions, which manifest themselves in spatial navigation and shape recognition. I claim, however, that these “hardwired intuitions” cannot capture full-blooded Euclidean geometry, which demands practice with cultural artifacts in various time-scales.

Opis:
Cognitive engineering is considered nowadays as interesting multidisciplinary domain that focuses on improving the relations between humans and the systems that are supervised and operated. The industrial automation and control systems (IACS) in hazardous plants are increasingly computerized and perform various safety functions. These are designed and implemented according to the functional safety concept. The objective is to maintain high performance / productivity and reduce various risks related to identified hazards and threats. An approach is proposed to apply selected cognitive engineering methods for verifying the design of the functional safety technology implemented in given hazardous plant in context of defined safety functions, operator interfaces, communication means and procedures. The methodology developed might be applied for functional safety management in life cycle of industrial hazardous plants and oil port terminals.

Rules are a common symbolic model of knowledge. Rule-based systems share roots in cognitive science and artificial intelligence. In the former, they are mostly used in cognitive architectures; in the latter, they are developed in several domains including knowledge engineering and machine learning. This paper aims to give an overview of these issues with the focus on the current research perspective of artificial intelligence. Moreover, in this setting we discuss our results in the design of rule-based systems and their applications in context-aware and business intelligence systems.

Opis:
A metaheuristic proposed by us recently, Ant Colony Optimization (ACO) hybridized with socio-cognitive inspirations, turned out to generate interesting results compared to classic ACO. Even though it does not always find better solutions to the considered problems, it usually finds sub-optimal solutions usually. Moreover, instead of a trial-and-error approach to configure the parameters of the ant species in the population, in our approach, the actual structure of the population emerges from predefined species-to-species ant migration strategies. Experimental results of our approach are compared against classic ACO and selected socio-cognitive versions of this algorithm.

Opis:
It is often claimed that structured collections of individuals with mental or cognitive states—such collections as courts, countries, and corporations—have mental or cognitive states of their own. The existing critical literature casts substantial doubt on this claim. In this paper, I evaluate a defensive move made by some proponents of the view that groups have mental or cognitive states of their own: to concede that group states and individual states aren’t of the same specific natural kinds, while holding that groups instantiate different species of mental or cognitive states—perhaps a different species of cognition itself—from those instantiated by humans. In order to evaluate this defense of group cognition, I present a view of natural kinds—or at least of the sort of evidence that supports inferences to sameness of natural kind—a view I have previously dubbed the ‘tweak-and-extend’ theory, as well as a theory of cognitive systems. Guided by the tweak-and-extend approach, I arrive at a tentative conclusion: that what is common to models of individual cognitive processing and models of group processing does not suffice to establish sameness of cognitive (or mental) kinds, properties, or state-types across individuals and extant groups, not even at a generic level.

W pracy są przedstawione najważniejsze zagadnienia związane z tematyką kognitywnej kategoryzacji dla kognitywnych systemów informacyjnych. Początkowo jest dokonana klasyfikacja systemów kognitywnej analizy danych oraz ich geneza i rozwój, a w dalszej części pracy omówiona jest klasa systemów UBMSS (Understanding Based Management Support Systems). Klasa UBMSS jest swoistego rodzaju automatycznym wspomaganiem procesu podejmowania decyzji strategiczno-finansowych przedsiębiorstw. W odniesieniu do omawianej tematyki klasa systemów UBMSS jest przedstawiona jako element wspomagający zarządzanie jednostkami.
Key problems of cognitive categorization in cognitive information systems are presented in the publication. Cognitive data analysis systems will first be classified, then their genesis and development will be presented, and then their main class will be discussed - UBMSS (Understanding Based Management Support Systems). UBMSS systems provide automatic support for the strategic and financial decision-making process in enterprises. Due to the subject discussed here, UBMSS systems will be presented as assets supporting the management of units. This publication presented intelligent systems for cognitive data analysis and categorization with a particular emphasis on strategic analysis systems used to analyse financial and economical data. This type of systems used to interpret, analyse and reason work following the operating principles of cognitive information system. Cognitive systems interpret all data by extracting semantic levels from them. Thus the course of human processes of leaning about the described phenomenon becomes the foundation for developing cognitive systems which are called cognitive data analysis systems.

Opis:
The article deals with the ancient metrology and a possible recognition of the rules determining ornamentation observed on Attic geometric pottery. While referring to former studies, the author presents ornamentation of Attic geometric pottery, revealing an exceptional standardisation and repetitiveness of elements, as having two developmental tendencies. One concerns horizontal arrangement of decorative motifs, placed in surrounding belts, while the other decoration is put in vertical panels, focusing. These both tendencies in the course of development of Attic geometric period become one harmonized whole. It is also possible to demonstrate on an example of monumental became from Athens (inv. NM 804), that the vessel was exactly twice as tall as the biggest width of its body, as well as that ornaments covering its whole surface have been made according to an accepted module. The author suggests that such a way of thinking and ordering activities should not be interpreted as proving the beginnings of classical mathematical thinking, which is to develop later. However, metrological analyses of ancient artefacts suggests that such objects as Attic geometric pottery may permit recognition of already existing disposition of its creators for visual representations of experienced reality and for attempts made to generalize these experiences.

This paper presents cognitive information systems for analysis and interpretation of economical data. The semantic data analysis systems are examples of UBMSS (Understanding Based Management Support Systems) systems presented in this publication on two examples - for estimation of the enterprise liquidity and analysis of the financial-cash flow. One of the UBMSS systems is dedicated to analysis of solvency (very good solvency, good solvency, poor or very poor solvency) of the enterprise ratio. The second one of the analyzed systems is used for assessing the cash flow structure - favourable or unfavourable structure of financial flow and risky structure of cash flow. UBMSS systems for cognitive analysis and semantic interpretation of the analyzed economical and financial data are also dedicated to analysis of other kinds of economical data, for example cash to current liabilities ratio, balance of payment, etc.

Opis:
Identification of learning styles supports Adaptive Educational Hypermedia Systems compiling and presenting tutorials custom in cognitive characteristics of each individual learner. This work addresses the issue: identifying the learning style of students, following the Kolb’s learning cycle. To this purpose, we propose a three-layers Fuzzy Cognitive Map (FCM) in conjunction with a dynamic Hebbian rule for learning styles recognition. The form of FCMs is designed by humans who determine its weighted interconnections among concepts. But the human factor may not be as reliable as it should be. Thus, a FCM model of the system allowing the adjustment of its weights using additional learners’ characteristics such as the Learning Ability Factors. In this article, two consecutively interconnected FCM (in the form of a three layer FCM) are presented. The schema’s efficiency has been tested and compared to known results after a fine-tuning of the weights of the causal interconnections among concepts. The simulations results of training the process system verify the effectiveness, validity and advantageous characteristics of those learning techniques for FCMs. The online recognition of learning styles by using threelayer Fuzzy Cognitive Map improves the accuracy of recognition obtained using Bayesian Networks that uses quantitative measurements of learning style taken from statistical samples. This improvement is due to the fuzzy nature of qualitative characterizations (such as learning styles), and the presence of intermediate level nodes representing Learning Ability Factors. Such factors are easily recognizable characteristics of a learner to improve adjustment of weights in edges with one end in the middle-level nodes. This leads to the establishment of a more reliable model, as shown by the results given by the application to a test group of students.

Opis:
Legal translation is a highly skilled task. It has even been described as the “ultimate linguistic challenge” (Harvey 2002: 177). However, law firms or corporations that procure translations from self- employed translation practitioners often find the intricacies of the task difficult to perceive. Following extensive fieldwork examining how legal translation is commissioned and performed in ‘outstitutional’ contexts, I have developed a multidimensional model which illustrates the legal translator’s textual agency, aimed at conveying the complexities of translation performance to clients and other stakeholders. It may also serve to train fledgling legal translators, and to heighten practising translators’ awareness of their overall task. The impetus for the model sprang primarily from findings of serious information asymmetry and goal divergence in the market, and evidence that actors involved do not grasp (a) the need for legal translators to be fully briefed, or (b) the layers of skills involved. 
Tłumaczenie prawne jest zadaniem wymagającym wysokich kwalifikacji. Zostało nawet opisane jako „największe wyzwanie językowe” (Harvey 2002: 177). Jednak firmy prawnicze lub korporacje, które zamawiają tłumaczenia od samozatrudnionych tłumaczy często nie zauważają zawiłości tego zadania. Po przeprowadzeniu szeroko zakrojonych badań terenowych, analizując, w jaki sposób zlecane jest tłumaczenie prawne i przeprowadzane w kontekście „pozainstytucjonalnym”, opracowałam wielowymiarowy model, który ilustruje złożoności wykonania tłumaczenia. Może również służyć kształceniu początkujących tłumaczy prawniczych i zwiększaniu świadomości tłumaczy na temat ich zadania.

Procedury takiego wnioskowania semantycznego oparte są o model rezonansu kognitywnego i zostały zaaplikowane do zadania znaczeniowej interpretacji wybranego rodzaju zobrazowań diagnostycznych centralnego układu nerwowego jako modułu inteligentnej analizy w systemach informacyjnych. Prezentowana w pracy aplikacja ma charakter badawczy i służy opracowaniu skutecznych metod wykrywania poszukiwanych zmian na pewnym zbiorze danych pochodzących z badań magnetycznorezonansowych struktur rdzenia kręgowego.
This paper demonstrates that AI methods, in particular linguistic mechanisms of semantic meaning reasoning can be applied to the development of intelligent IT systems. They enable also conducting an in-depth meaning analysis in the presented DDS information systems. This paper presents also IT mechanisms of object meaning description on selected examples of spinal cord image analysis. The procedures for such semantic reasoning are based on the model of cognitive resonance. They have been applied to the task of meaning interpretation of a selected type of central nervous system diagnostic images, as an intelligent analysis module in IT systems. The application presented in this paper is of research character and it serves the preparation of efficient lesion detection methods applied to a dataset originating from magnetic and resonance examinations of the spinal cord structures.

Opis:
Systemy UBIAS, opisywane we wcześniejszych pracach, zapoczątkowały powstanie nowej generacji inteligentnych systemów rozumienia danych obrazowych, w szczególności medycznych. Systemy te są również przydatne przy operowaniu w multimedialnych bazach danych ilekroć wykonywane operacje (wyszukiwania, grupowania, raportowania) muszą być oparte na merytorycznym sensie zawartości obrazu, a nie na formie informacji obrazowej. Systemy E-UBIAS przedstawiane w niniejszej pracy stanowią nową kategorię kognitywnych systemów przystosowanych do semantycznej interpretacji obrazu. Innowacją wprowadzoną w systemach E-UBIAS i poszerzającą możliwości wcześniejszych systemów UBIAS jest wprowadzenie nowego elementu zdobywania wiedzy podczas normalnej eksploatacji systemu (czyli swoistego procesu uczenia). Wskazano na możliwości zastosowania tych systemów, a także na nowe możliwości ich wykorzystania do pozyskiwania danych obrazowych traktowanych jako charakterystyki biometryczne.
In previous papers given by authors the special class of computer vision systems was introduced and discussed. Such system named UBIAS was dedicated to cognitive analysis of images - especially medical ones. Replacing in UBIAS systems the image analysis and pattern recognition processes by cognitive resonance and automatic understanding we in fact introduce new class of vision systems which possibilities and advantages are not fully recognized until yet. Nevertheless the UBIAS image understanding systems have limitations related to "hand made" knowledge acquisition and representation process, which is necessary before starting the UBIAS system functioning. Sometimes collection of rules given by expert is too narrow, sometimes presentation of such rules in linguistic form used in UBIAS system is difficult, sometimes there are also another sources of problem - result is the same: The efficiency and quality of understanding of the images under consideration is not satisfactory. In all cases, when automatic understanding of the image using UBIAS methods is not good enough the solution can be E-UBIAS (Extended Understand-ing-Based Image Analysis System), which is presented in this article. The E-UBIAS systems set a new category of intelligent vision systems, which extend the possibilities of UBIAS towards acquiring knowledge and learning processes. In E-UBIAS systems two types of knowledge are used as a support of cognitive resonance procedures, leading to automatic understanding of the image semantic content. First type knowledge is acquired from experts ad is represented in linguistic form in graph-grammar structures used in typical cognitive resonance process. This is deductive part of the system. Second type knowledge is registered during normal work of the system. Every reasoning process performed by the system for some particular image give us new piece of information, which can be concatenated with other similar pieces coming from previous experiences. Such part of system is inductive one. Moreover systems belonging to the E-UBIAS class can be also used for collection of biometric characteristics for every person, which image was analyzed by the system and which semantic description was processed for automatic understanding purposes. It can be very useful in many security applications.

Opis:
W pracy opisano nową klasę specjalistycznych systemów informacyjnych, nazwanych UBIAS. Systemy takie należą do klasy kognitywnych systemów wnioskujących i są przeznaczone do znaczeniowej analizy skomplikowanych elementów nowoczesnych multimedialnych baz danych. Systemy UBIAS nadają się zwłaszcza do wydobywania znaczeniowej warstwy z informacji przedstawionej w postaci obrazów. W pracy przedstawiane są argumenty uzasadniające twierdzenie, że znaczenie obrazu i jego forma to dwa rozłączne aspekty, z których ten pierwszy jest zdecydowanie ważniejszy. Przedstawiane rozważania prowadzone są w sposób ogólny, ale eksperymenty, które doprowadziły do zdefiniowania systemów UBIAS odwoływały się w większości do semantycznej analizy obrazów biomedycznych.
Paper describes new class of cognitive information systems named UBIAS (Understanding-Based Image Analysis Systems). Such systems belong to the group of cognitive reasoning computer systems and are dedicated for the semantic analysis of the images. In contemporary information systems many types of multimedial (e.g. visual) patterns are used, and semantic oriented analysis of such type of information is necessary. The general idea of automatic understanding of the images can be applied to any type of image, but in paper only biomedical images are taken into account. For diagnostic purposes and for intelligent selection of proper medical images from the big and not annotated databases (e.g., Internet) we must consider semantic content of the images, because reasoning based on image information as well as selection suitable image information needs semantic analysis of the image merit content. Typical image processing, analysis and also pattern recognition or clustering is definitely not satisfied. For automatic image understanding we propose UBIAS systems. Such systems are predecessors of a new generation of intelligent systems for understanding of visual data and using this data in many purposes. Possible applications spread out from medical diagnosis, throw searching in visual databases up to extraction biometric characteristics for personal identification. Additionally such systems are very useful in the tasks of intelligent semantic i.e. based on merit content (and not only with regard to the form), information management in multimedia databases. Particular systems dedicated to semantic analysis of the images were described in previous authors papers, but the presented paper present the class of UBIAS systems using general description instead of examples.
