Natural Language Interfaces to Data
Abdul Quamar, Vasilis Efthymiou, Chuan Lei +1
Recent advances in NLU and NLP have resulted in renewed interest in natural language interfaces to data, which provide an easy mechanism for non-technical users to access and query…
Scaling Knowledge Graph Embedding Models
Nasrullah Sheikh, Xiao Qin, Berthold Reinwald +1
Developing scalable solutions for training Graph Neural Networks (GNNs) for link prediction tasks is challenging due to the high data dependencies which entail high computational c…
BI-REC: Guided Data Analysis for Conversational Business Intelligence
Venkata Vamsikrishna Meduri, Abdul Quamar, Chuan Lei +2
Conversational interfaces to Business Intelligence (BI) applications enable data analysis using a natural language dialog in small incremental steps. To truly unleash the power of…
Medical Entity Disambiguation Using Graph Neural Networks
Alina Vretinaris, Chuan Lei, Vasilis Efthymiou +2
Medical knowledge bases (KBs), distilled from biomedical literature and regulatory actions, are expected to provide high-quality information to facilitate clinical decision making.…
To Share, or not to Share Online Event Trend Aggregation Over Bursty Event Streams
Olga Poppe, Chuan Lei, Lei Ma +2
Complex event processing (CEP) systems continuously evaluate large workloads of pattern queries under tight time constraints. Event trend aggregation queries with Kleene patterns a…
Sharon: Shared Online Event Sequence Aggregation
Olga Poppe, Allison Rozet, Chuan Lei +2
Streaming systems evaluate massive workloads of event sequence aggregation queries. State-of-the-art approaches suffer from long delays caused by not sharing intermediate results o…
GRETA: Graph-based Real-time Event Trend Aggregation
Olga Poppe, Chuan Lei, Elke A. Rundensteiner +1
Streaming applications from algorithmic trading to traffic management deploy Kleene patterns to detect and aggregate arbitrarily-long event sequences, called event trends. State-of…
Event Trend Aggregation Under Rich Event Matching Semantics
Olga Poppe, Chuan Lei, Elke A. Rundensteiner +1
Streaming applications from health care analytics to algorithmic trading deploy Kleene queries to detect and aggregate event trends. Rich event matching semantics determine how to…
Property Graph Schema Optimization for Domain-Specific Knowledge Graphs
Chuan Lei, Rana Alotaibi, Abdul Quamar +2
Enterprises are creating domain-specific knowledge graphs by curating and integrating their business data from multiple sources. The data in these knowledge graphs can be described…
