Spatio-Temporal-Keyword Pattern Queries over Semantic Trajectories with Hermes@Neo4j
نویسندگان
چکیده
In this paper, we demonstrate Hermes@Neo4j1, an extension of Neo4j graph DMBS for semantic trajectories of moving objects, on the so-called Spatio-Temporal-Keyword Pattern queries. For this purpose, our engine exploits on hybrid Spatio-TemporalKeyword (STK) index structures, also boosted by an appropriate selectivity estimation model. Hermes@Neo4j functionality is demonstrated over synthetic and real semantic trajectory

An Approach for Spatial Pattern Matching in Simulation Trajectories
For models that include spatial aspects, the description and recognition of spatio-temporal patterns is an important building block for the analysis of simulation trajectories. We propose an approach that makes use of user-definable qualitative spatial relations between moving entities to represent simulation trajectories as directed labeled graph. In this graph, spatio-temporal patterns can be...
متن کاملMultimedia at Work Editor : Tiziana Catarci University of Rome
tem provides integrated support for spatiotemporal and semantic queries for video.1 A knowledge base—consisting of a fact base and a comprehensive rule set implemented in Prolog— handles spatio-temporal queries. These queries contain any combination of conditions related to direction, topology, 3D relationships, object appearance, trajectory projection, and similaritybased object trajectories. ...
متن کاملA Video Database Management System
We develop a Web-based video database management system, named BilVideo, providing an integrated support for both spatio-temporal and semantic (keyword, event/activity and category-based) queries on video data. In this paper, we introduce the architecture of BilVideo and its SQL-like textual video query language that has the capability to handle a broad range of spatio-temporal queries, which m...
متن کاملSpatio-Temporal Querying in Video Databases
In this paper a video data model that allows efficient and effective representation and querying of spatio-temporal properties of objects is presented. The data model is focused on the semantic content of video streams. Objects, events, activities performed by objects are main interests of the model. The model supports fuzzy spatial queries including querying spatial relationships between objec...
متن کاملExploiting Semantic Predications in a Graph Database
Knowledge extraction using semantic relations is crucial for accurate and valid knowledge management in biomedicine. The Semantic MEDLINE Database (SemMedDB) contains semantic predications extracted with the SemRep semantic interpreter. Predications are structured as subject-predicate-object triples and can be represented as a directed network. Arguments correspond to UMLS Metathesaurus concept...
