Linking Semantic Desktop Data to the Web of Data

Abstract

Abstract. The goal of the Semantic Desktop is to enable better organization of the personal information on our computers, by applying semantic technologies on the desktop. However, information on our desktop is often incomplete, as it is based on our subjective view, or limited knowledge about an entity. On the other hand, the Web of Data contains information about virtually everything, generally from multiple sources. Connecting the desktop to the Web of Data would thus enrich and complement desktop information. Bringing in information from the Web of Data automatically would take the burden of searching for information off the user. In addition, connecting the two networks of data opens up the possibility of advanced personal services on the desktop.Our solution tackles the problems raised above by using a semantic search engine for the Web of Data, such as Sindice, to find and retrieve a relevant subset of entities from the web. We present a matching framework, using a combination of configurable heuristics and rules to compare data graphs, that achieves a high degree of precision in the linking decision. We evaluate our methodology with real-world data; create a gold standard from relevance judgements by experts, and we measure the performance of our system against it. We show that it is possible to automatically link desktop data with web data in an effective way.

Ontology-driven collaborative annotation in shared workspaces

“…The main goal of this project was to support collaboration among knowledge workers, through the integration of existing applications, achieved by the definition of an open-source framework for implementing semantic desktops, based on a set of ontologies. A proposal to connect the Semantic Desktop to the Web of Data, which inspired the future enhancement of Sem T++ with a connection to open datasets (mentioned in Section 4.1), is discussed in [10].…”

Shared and Personal Views on Collaborative Semantic Tables

“…In particular, the NEPOMUK project (nepomuk.semanticdesktop.org) defined an open source framework for implementing semantic desktops, aimed at the integration of existing applications and the support to collaboration among knowledge workers, while [14] presents an interesting model connecting the Semantic Desktop to the Web of Data.…”

An Integrated Support to Collaborative Semantic Annotation

“…This approach aims at supporting the collaboration among knowledge workers, thanks to an open-source framework enabling the implementation of semantic desktops that integrate different applications and ontologies. A further development toward the integration of Web of Data sources can be found in [17].…”
