Research Challenges in Relational Database Management Systems for LLM Queries
Kerem Akillioglu, Anurag Chakraborty, Sairaj Voruganti +1
Large language models (LLMs) have become essential for applications such as text summarization, sentiment analysis, and automated question-answering. Recently, LLMs have also been…
LazyVLM: Neuro-Symbolic Approach to Video Analytics
Xiangru Jian, Wei Pang, Zhengyuan Dong +2
Current video analytics approaches face a fundamental trade-off between flexibility and efficiency. End-to-end Vision Language Models (VLMs) often struggle with long-context proces…
BigDocs: An Open Dataset for Training Multimodal Models on Document and Code Tasks
Juan Rodriguez, Xiangru Jian, Siba Smarak Panigrahi +40
Multimodal AI has the potential to significantly enhance document-understanding tasks, such as processing receipts, understanding workflows, extracting data from documents, and sum…
Incremental Sliding Window Connectivity over Streaming Graphs
Chao Zhang, Angela Bonifati, M. Tamer Özsu
We study index-based processing for connectivity queries within sliding windows on streaming graphs. These queries, which determine whether two vertices belong to the same connecte…
Indexing Techniques for Graph Reachability Queries
Chao Zhang, Angela Bonifati, M. Tamer Özsu
We survey graph reachability indexing techniques for efficient processing of graph reachability queries in two types of popular graph models: plain graphs and edge-labeled graphs.…
Efficient Execution of SPARQL Queries with OPTIONAL and UNION Expressions
Lei Zou, Yue Pang, M. Tamer Özsu +1
The proliferation of RDF datasets has resulted in studies focusing on optimizing SPARQL query processing. Most existing work focuses on basic graph patterns (BGPs) and ignores othe…
Foundations and Scoping of Data Science
M. Tamer Özsu
There has been an increasing recognition of the value of data and of data-based decision making. As a consequence, the development of data science as a field of study has intensifi…
Optimizing Differentially-Maintained Recursive Queries on Dynamic Graphs
Khaled Ammar, Siddhartha Sahu, Semih Salihoglu +1
Differential computation (DC) is a highly general incremental computation/view maintenance technique that can maintain the output of an arbitrary and possibly recursive dataflow co…
The Case for Distributed Shared-Memory Databases with RDMA-Enabled Memory Disaggregation
Ruihong Wang, Jianguo Wang, Stratos Idreos +2
Memory disaggregation (MD) allows for scalable and elastic data center design by separating compute (CPU) from memory. With MD, compute and memory are no longer coupled into the sa…
GSmart: An Efficient SPARQL Query Engine Using Sparse Matrix Algebra -- Full Version
Yuedan Chen, M. Tamer Özsu, Guoqing Xiao +2
Efficient execution of SPARQL queries over large RDF datasets is a topic of considerable interest due to increased use of RDF to encode data. Most of this work has followed either…
The Future is Big Graphs! A Community View on Graph Processing Systems
Sherif Sakr, Angela Bonifati, Hannes Voigt +38
Graphs are by nature unifying abstractions that can leverage interconnectedness to represent, explore, predict, and explain real- and digital-world phenomena. Although real users a…
