  - Rok 2013

  Voice over IP is a widely used concept with regard to a realization technology of different types of telephony systems, including those that are used in enterprises. Such systems of a call procesing component and a set of desk endpoints that are pervasove from a user perspective. Those andpoints are usually not mobile, but in result can deliver a much greater set of functions needed in an everyday office work. Those functions also...

• Context-aware User Modelling and Generation of Recommendations in Recommender Systems

  Publikacja

  • A. Karpus

  - Rok 2018

  Recommender systems are software tools and techniques which aim at suggesting new items that may be of interest to a user. This dissertation is focused on four problems in recommender systems domain. The first one is context-awareness, i.e. how to obtain relevant contextual information, how to model user preferences in a context and use them to make predictions. The second one is multi-domain recommendation, which aim at suggesting...

  • C. Sanin
  • E. Szczerbicki

  - Advances in Intelligent Systems and Computing - Rok 2019

  Visual content searching, browsing and retrieval tools have been a focus area of interest as they are required by systems from many different domains. Context-based, Content-Based, and Semantic-based are different approaches utilized for indexing/retrieving, but have their drawbacks when applied to systems that aim to mimic the human capabilities. Such systems, also known as Cognitive Systems, are still limited in terms of processing...

• Towards better understanding of context-aware knowledge transformation

  Publikacja

  • M. Owoc
  • P. Weichbroth
  • K. Żuralski

  - Annals of Computer Science and Information Systems - Rok 2017

  Considering different aspects of knowledge functioning, context is poorly understood in spite of intuitively identifying this concept with environmental recognition. For dynamic knowledge, context especially seems to be an essential factor of change. Investigation on the impact of context on knowledge dynamics or more generally on the relationship between knowledge and its contextual interpretation is important in order to understand...

• A New Model for context aware applications analysis and design

  Publikacja

  • H. Krawczyk
  • S. Nasiadka

  - Rok 2011

  W artykule zostały opisane aplikacje kontekstowe, które działają w przestrzeniach inteligentnych, oraz zostały przeanalizowane ich właściwości. Na podstawie analizy zaproponowano nowe podejście do ich modelowania które zapewnia oddzielenie logiki aplikacji w zakresie adaptacji (do zmian środowiska) od jej realizacji. Zostały wykorzystane MVC i modele zmian stanu. Zaproponowano ilościową miarę poziomu kontekstowości a także sposób...

• A CONTEXT IN RECOMMENDER SYSTEMS

  Publikacja

  • A. Karpus

  - Rok 2016

  Recommender systems aim to propose potentially interesting items to a user based on his preferences or previous interaction with the system. In the last decade, researcher found out that known recommendation techniques are not sufficient to predict user decisions. It has been noticed that user preferences strongly depend on the context in which he currently is. This raises new challenges for the researchers such as how to obtain...

• Multi-domain and Context-Aware Recommendations Using Contextual Ontological User Profile

  Publikacja

  • A. Karpus
  • K. Goczyła

  - Rok 2022

  Recommender Systems (RS) became popular tools in many Web services like Netflix, Amazon, or YouTube, because they help a~user to avoid an information overload problem. One of the types of RS are Context-Aware RS (CARS) which exploit contextual information to provide more adequate recommendations. Cross-Domain RS (CDRS) were created as a response to the data sparsity problem which occurs when only few users can provide reviews or...

• 1D convolutional context-aware architectures for acoustic sensing and recognition of passing vehicle type

  Publikacja

  • A. Kurowski
  • S. Zaporowski
  • A. Czyżewski

  - Rok 2020

  A network architecture that may be employed to sensing and recognition of a type of vehicle on the basis of audio recordings made in the proximity of a road is proposed in the paper. The analyzed road traffic consists of both passenger cars and heavier vehicles. Excerpts from recordings that do not contain vehicles passing sounds are also taken into account and marked as ones containing silence....

• Energy-Aware Scheduling for High-Performance Computing Systems: A Survey

  Publikacja

  • B. Kocot
  • P. Czarnul
  • J. Proficz

  - ENERGIES - Rok 2023

  High-performance computing (HPC), according to its name, is traditionally oriented toward performance, especially the execution time and scalability of the computations. However, due to the high cost and environmental issues, energy consumption has already become a very important factor that needs to be considered. The paper presents a survey of energy-aware scheduling methods used in a modern HPC environment, starting with the...
