Zmanipulowane treści dezinformacyjne wykorzystują mechanizmy uprzedzeń poznawczych, wzorców behawioralnych lub emocjonalnych oraz nawyki użytkowników, dlatego są tak trudne do rozróżnienia od faktów. Celem niniejszego rozdziału jest analiza tych kwestii zarówno z perspektywy bezpieczeństwa poznawczego, jak i dziedziny Text Mining, wskazująca na potrzebę interdyscyplinarnego podejścia do przeciwdziałania dezinformacji. Wiedza o metodach Text Mining jest nadal mało znana szerokiemu gronu odbiorców, tak samo jak rodząca się dopiero dziedzina bezpieczeństwa poznawczego. Rezultat mariażu tych dziedzin w kontekście przeciwdziałania dezinformacji może przyczynić się do przejścia z technik defensywnych i naprawczych do ofensywnych i prewencyjnych.

However, to be fully supportive, these ASR systems must meet certain requirements dictated by market realities: high accuracy of speech recognition and low rate of errors, the possibility of additional training the model, and the possibility of on-premise system installation. Therefore, the aim of this paper is to perform a comparative analysis of leading ASR systems available on the Polish market for the needs of conducting medical interviews. We selected three systems, Google ASR, Microsoft ASR, and Techmo ASR, and we compared their performance on a prepared data set of medical-related expressions spoken in Polish. The results of our analysis indicated that there are minor discrepancies in the accuracy of speech recognition between all three evaluated ASR systems, whereas only two ASR systems met the raised requirements, in both cases partially. Still, they all exhibited specific problems in recognising word endings or word boundaries. We were able to categorise such problems into: Misrecognitions, Quality Problems, and Word Boundaries, varying in their level of influence on the further speech recognition process. Our research findings are expected to provide valuable insights to a wide range of stakeholders facilitating the development of tailored speech recognition solutions that meet the specific needs of medical sector.

The paper focuses on the food industry and therefore we analyse cooking recipe texts available on one of the many Internet sites with recipes. Our analysis consists of clusterization processes, classification models and concept linking associations. Each of these techniques contributes to the selection of marketing tools applied to analysis of websites. Clustering allows to identify groups of recipes that use specific ingredients produced by specific companies. Classification assigns newly added recipes to a suitable category, which afterwards may be used to prepare advertising materials appropriate for selected category. Concept linking helps to discover associations between products and cooking accessories.

As a result, Question Answering systems have evolved and can classify and answer questions in an intuitive yet communicative way. However, the lack of large volumes of labeled data prevents large-scale training and development of Question Answering systems, confirming the need for further research. This paper aims to handle this real-world problem of lack of labeled datasets by applying a pseudolabeling technique relying on a neural network transformer model DistilBERT. In order to evaluate our contribution, we examined the performance of a text classification transformer model that was fine-tuned on the data subject to prior pseudolabeling. Research has shown the usefulness of the applied pseudo-labeling technique on a neural network text classification transformer model DistilBERT. The results of our analysis indicated that the model with additional pseudo-labeled data achieved the best results among other compared neural network architectures. Based on that result, Question Answering systems may be directly improved by enriching their training steps with additional data acquired cost-effectively.

However, there is no unique measurement system that would be widely accepted and applied within various urban areas to verify whether a given city is developing in a sustainable way. The aim of this paper is to apply the TOPSIS algorithm on the basis of selected urban indicators, in order to evaluate the progress of a single city towards the concept of sustainable development observed over a longer period of time. A capital city of Poland, Warsaw, faces several challenges associated with development policy evaluation, thus confirming the need for this research. We meticulously selected 48 indicators from the economic, social and environmental areas as an input for TOPSIS algorithm, which allowed us to calculate a new proposed aggregated index for evaluating urban policy on the example of Warsaw. Research has shown usefulness of applied TOPSIS algorithm in assessing the long-run development of an urban area towards the concept of a sustainable city. The results of our analysis indicated that over a period of ten years, during 2008-2017, the urban policy decision-making has been balancing the socio-economic and environmental aspects and the city of Warsaw has been developed in a sustainable manner.
