Initial Usage Analysis of DBpedia's Triple Pattern Fragments
نویسندگان
چکیده
Queryable Linked Data is available through several interfaces, including SPARQL endpoints and Linked Data documents. Recently, the popular DBpedia dataset was made available through a Triple Pattern Fragments interface, which proposes to improve query availability by dividing query execution between clients and servers. In this paper, we present an initial usage analysis of this interface so far. In 4 months time, the server had an availability of 99.999%, handling 4,455,813 requests, more than a quarter of which were served from cache. These numbers provide promising evidence that Triple Pattern Fragments are a viable strategy for live applications on top of public queryable datasets.

dbpedia's Triple Pattern Fragments: Usage Patterns and Insights
Queryable Linked Data is published through several interfaces, including sparql endpoints and Linked Data documents. In October 2014, the dbpedia Association announced an official Triple Pattern Fragments interface to its popular dbpedia dataset. This interface proposes to improve the availability of live queryable data by dividing query execution between clients and servers. In this paper, we ...
متن کاملReducing the Network Load of Triple Pattern Fragments by Supporting Bind Joins
The recently proposed Triple Pattern Fragment (TPF) interface aims at increasing the availability of Web-queryable RDF datasets [3]. To this end, the TPF proposal trades off an increased client-side query processing effort for a significant reduction of server load. However, an additional aspect of this trade-off is a very high network load. To mitigate this drawback we propose to extend the in...
متن کاملTrend and pattern analysis of runoff and sediment in different soil clay contents and surface rock fragments
Different factors affect the runoff and sediment production during storm conditions. Among different soil properties, clay content is one of the most important bonding agents for aggregation and infiltration. Rock fragments also affect hydrological and erosional processes, but these relationships in various soil clay contents or surface rock fragments may be positive or negative, thus examinati...
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 کاملLow-Cost Queryable Linked Data through Triple Pattern Fragments
For publishers of Linked Open Data, providing queryable access to their dataset is costly. Those that offer a public sparql endpoint often have to sacrifice high availability; others merely provide non-queryable means of access such as data dumps. We have developed a client-side query execution approach for which servers only need to provide a lightweight triple-pattern-based interface, enablin...
