Discovering and Querying Hybrid Linked Data
نویسندگان
چکیده
In this paper, we present a unified framework for discovering and querying hybrid linked data. We describe our approach to developing a natural language query interface for a hybrid knowledge base Wikitology, and present that as a case study for accessing hybrid information sources with structured and unstructured data through natural language queries. We evaluate our system on a publicly available dataset and demonstrate improvements over a baseline system. We describe limitations of our approach and also discuss cases where our system can complement other structured data querying systems by retrieving additional answers not available in structured sources.

Developing a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملFreshening up while Staying Fast: Towards Hybrid SPARQL Queries
Querying over cached indexes of Linked Data often suffers from stale or missing results due to infrequent updates and partial coverage of sources. Conversely, live decentralised approaches offer fresh results directly from the Web, but exhibit slow response times due to accessing numerous remote sources at runtime. We thus propose a hybrid query approach that improves upon both paradigms, offer...
متن کاملLoupe - An Online Tool for Inspecting Datasets in the Linked Data Cloud
The Linked Data initiative continues to grow making more datasets available; however, discovering the type of data contained in a dataset, its structure, and the vocabularies used still remains a challenge hindering the querying and reuse. VoID descriptions provide a starting point but a more detailed analysis is required to unveil the implicit vocabulary usage such as common data patterns. Suc...
متن کاملInteractive Querying Locating and Discovering Information
The once distinct information retrieval, database and hypertext technologies are converging and overlapping. In addition, a plethora of interactive visualisation techniques have been developed over recent years. This paper will examine the nature of interactive querying and retrieval in order to understand the common features between apparently diverse retrieval techniques and in so doing help ...
متن کاملSpEnD: Linked Data SPARQL Endpoints Discovery Using Search Engines
Linked data endpoints are online query gateways to semantically annotated linked data sources. In order to query these data sources, SPARQL query language is used as a standard. Although a linked data endpoint (i.e. SPARQL endpoint) is a basic Web service, it provides a platform for federated online querying and data linking methods. For linked data consumers, SPARQL endpoint availability and d...
