Special Issue Information

Dear Colleagues,

Data mining and machine learning have revolutionised many scientific fields. In information retrieval, systems can search the web, act as question-answering systems, work as personal assistants, work with chatbots, and search digital libraries.

Information retrieval systems can act as rankers, a typical task they share with recommendation systems. The two fields also share the ability to search efficiently and possibly in a personalised way in large corpora, knowledge bases, heterogeneous sources, content and digital libraries. Both compete in the same application areas. Both can advance with the integration of external knowledge, leading to knowledge-based systems.

Furthermore, the novel techniques of deep learning neural networks and transformers can advance both systems even more drastically, making them more similar and leading to convergence into a unique system type. 

This Special Issue addresses the above topics as well as the following topics:

  • The convergence of information retrieval and recommendation systems;
  • The architecture, the technology, the algorithms for searching, digesting, transforming, filtering, learning on massive data;
  • Real-time and online data processing and analysis;
  • Heterogeneous and multimedia content;
  • Pipelines and integration of machine learning tasks in the system;
  • Bias in data and its impact on system results;
  • Knowledge integration in the system;
  • Integration of context in question answering;
  • Personalisation and consideration of the user;
  • Privacy and robustness of the system;
  • Explainability of the system and its results;
  • Accountability of the pipeline;
  • Applications.

The paper concerns the problem of action-rule extraction when datasets are large. Such rules can be used to construct a knowledge base in a recommendation system. One of the popular approaches to construct action rules in such cases is to partition the dataset horizontally (personalization) and vertically. Different clustering strategies can be used for this purpose. Action rules extracted from vertical clusters can be combined and used as knowledge discovered from the horizontal clusters of the initial dataset. The number of extracted rules strongly depends on the methods used to complete that task. In this study, we chose a software package called SCARI recently developed by Sikora and his colleagues. It follows a rule-based strategy for action-rule extraction that requires prior extraction of classification rules and generates a relatively small number of rules in comparison to object-based strategies, which discover action rules directly from datasets. Correlation between attributes was used to cluster them. We used an agglomerative strategy to cluster attributes of a dataset and present the results by using a dendrogram. Each level of the dendrogram shows a vertical partition schema for the initial dataset. From all partitions, for each level, action rules are extracted and then concatenated. Their precision, the lightness, and the number of rules are presented and compared. Lightness shows how many action rules can be applied on average for each tuple in a dataset. Full article

Recommendation systems play a pivotal role in improving product competitiveness. Traditional recommendation models predominantly use centralized feature processing to operate, leading to issues such as excessive resource consumption and low real-time recommendation concurrency. This paper introduces a recommendation model founded on deep learning, incorporating edge computing and knowledge distillation to address these challenges. Recognizing the intricate relationship between the accuracy of deep learning algorithms and their complexity, our model employs knowledge distillation to compress deep learning. Teacher–student models were initially chosen and constructed in the cloud, focusing on developing structurally complex teacher models that incorporate passenger and production characteristics. The knowledge acquired from these models was then transferred to a student model, characterized by weaker learning capabilities and a simpler structure, facilitating the compression and acceleration of an intelligent ranking model. Following this, the student model underwent segmentation, and certain computational tasks were shifted to end devices, aligning with edge computing principles. This collaborative approach between the cloud and end devices enabled the realization of an intelligent ranking for product listings. Finally, a random selection of the passengers’ travel records from the last five years was taken to test the accuracy and performance of the proposed model, as well as to validate the intelligent ranking of the remaining tickets. The results indicate that, on the one hand, an intelligent recommendation system based on knowledge distillation and edge computing successfully achieved the concurrency and timeliness of the existing remaining ticket queries. Simultaneously, it guaranteed a certain level of accuracy, and reduced computing resource and traffic load on the cloud, showcasing its potential applicability in highly concurrent recommendation service scenarios.
