SPARQL-MM - Extending SPARQL to Media Fragments
نویسندگان
چکیده
Interconnecting machine readable data with multimedia assets and fragments has recently become a common practice. But specific retrieval techniques for the so called Semantic Multimedia data are still lacking. On our poster we present SPARQL-MM, a function set that extends SPARQL to Media Fragment facilities by introducing spatiotemporal filter and aggregation functions.

Enabling access to Linked Media with SPARQL-MM
The amount of audio, video and image data on the web is immensely growing, which leads to data management problems based on the hidden character of multimedia. Therefore the interlinking of semantic concepts and media data with the aim to bridge the gap between the document web and the Web of Data has become a common practice and is known as Linked Media. However, the value of connecting media ...
متن کاملSCRY: Extending SPARQL with Custom Data Processing Methods for the Life Sciences
An ever-growing amount of life science databases are (partially) exposed as RDF graphs (e.g. UniProt, TCGA, DisGeNET, Human Protein Atlas), complementing traditional methods to disseminate biodata. The SPARQL query language provides a powerful tool to rapidly retrieve and integrate this data. However, the inability to incorporate custom data processing methods in SPARQL queries inhibits its app...
متن کاملSWEEP: a Streaming Web Service to Deduce Basic Graph Patterns from Triple Pattern Fragments
The Triple Pattern Fragments (TPF) interface demonstrates how it is possible to publish Linked Data at low-cost while preserving data availability. But, data providers hosting TPF servers are not able to analyze the SPARQL queries they execute because they only receive and evaluate subqueries with one triple pattern. Understanding the executed SPARQL queries is important for data providers for ...
متن کاملSPARQL-DL Implementation Experience
Recently, SPARQL-DL was introduced in [7] as a rich query language for OWL-DL ontologies. It provides an OWL-DL-like semantics for SPARQL basic graph patterns which involves as special cases both conjunctive ABox queries and mixed TBox/RBox/ABox queries over Description Logic (DL) ontologies. This paper describes the implementation of a SPARQL-DL query engine and discusses several optimizations...
متن کاملOn Demand SPARQL Extension: A Case Study of Extending Geo-SPARQL for Sensor Data Exploration in Semantic Cities
SPARQL is the standard language for querying on RDF data, however it lacks support for many useful functions that a semantic city service may require. In this paper, a system is discussed where functions written in commonly known programming language like Java can be instantly added to the SPARQL function library, thereby decreasing development time as well as keeping the underlying implementat...
