Distributed Storage of Large Knowledge Graphs with Mobility Data

Dear Colleagues,

In today’s big data and AI era, a huge amount of mobility data is generated from heterogeneous sources, such as social media, GPS, and the Internet of Things (IoT). Managing and analyzing such big mobility data, often organized in the form of knowledge graphs (KGs), is essential in many real-world applications including location-based services, recommender systems, smart transportation, and digital economy. However, there are still several great challenges in mobility data management and mining. For example, mobility data are often received incrementally over time and should be stored in a distributed manner. As another example, mobility data often contain sensitive user information and should be analyzed with privacy concerns. To bridge these gaps, researchers and engineers are developing new and enhancing existing techniques and methods to improve the performance of mobility data analytics.

The goal of this Special Issue is to provide an overview of the latest developments regarding mobility data, knowledge graphs, and distributed systems. Both theoretical and technical aspects are of interest. Interdisciplinary approaches are also highly welcome.

Topics of interest include but are not limited to the following:
•    Distributed and/or stream processing of mobility data and knowledge graphs;
•    Data structures and algorithms for mobility data and knowledge graphs;
•    Machine learning and deep learning on mobility data and knowledge graphs;
•    Federated learning on mobility data and knowledge graphs;
•    Security and privacy issues on mobility data and knowledge graph analytics;
•    Fairness, transparency, and interpretability of mobility data and knowledge graph analytics;
•    Other novel applications and emerging technologies for mobility data and knowledge graphs.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Future Internet is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
