Parallel Materialization of Datalog Programs with Spark for Scalable Reasoning
As the volume of semantic data increases rapidly, semantic reasoning becomes a very challenging task. Existing scalable reasoners focus on fragments of OWL 2 RL (eg. RDFS, OWL Horst), and cannot support Semant...

A Lightweight Evaluation Framework for Table Layouts in MapReduce Based Query Systems
Table layout determines the way how the relational row-column data values are organized and stored. In recent years, considerable candidates have been developed in MapReduce based query systems; they differ on...

Scalable Horn-Like Rule Inference of Semantic Data Using MapReduce
Semantic data analysis tasks benefit much from rule inference, which derives implicit knowledge from explicit information. Recently, available semantic data from the Web, sensor readings, semantic databases an...

Consistent Query Answering Based on Repairing Inconsistent Attributes with Nulls
Although integrity constraints can successfully capture data semantics, the actual data in the database often violates such constraints. A Consistent Query Answer (CQA) in a possibly inconsistent database is a...

Template Matching and Monte Carlo Markova Chain for People Counting under Occlusions
It is challenging to count and analyze people in crowds due to the changes of lighting, occlusions, shadows, backgrounds, and weather conditions. Especially for the occlusion problem, until now, it is still il...

Robust Face Recognition with Light Compensation
This paper proposes a face recognition method which is based on a Generalized Probabilistic Descent (GPD) learning rule with a three-layer feedforward network. This method aims to recognize faces in a loosely ...
