With the continued growth of online semantic information, the processes of searching and managing this massive scale and heterogeneous content have become increasingly challenging. In this work, we present PowerAqua, an ontologybased Question Answering system that is able to answer queries by locating and integrating information, which can be distributed across heterogeneous semantic resources. We provide a complete overview of the system including: the research challenges that it addresses…

PowerAqua : open question answering on the Semantic Web

The experiences of this work can be extrapolated to a variety of end-user applications that wish to open up to large scale and heterogeneous structured datasets, to be able to exploit effectively what possibly is the greatest wealth of data in the history of Artificial Intelligence.

Is Question Answering fit for the Semantic Web?: A survey

A survey on ontology-based Question Answering (QA), which has emerged in recent years to exploit the opportunities offered by structured semantic information on the Web, and the potential of this technology to go beyond the current state of the art to support end-users in reusing and querying the SW content.

Semantic search engine with an intuitive user interface

This paper presents a search system of user interface that is more user-friendly than widely known graph-based solutions and has unavoidably lower accuracy.

University ’ s repository of research publications and other research outputs Is question answering fit for the Semantic Web ?

GoRelations: Towards an Intuitive Query System for RDF Data

A compromise is described in which non-experts specify a graphical “skeleton” for a query and annotate it with freely chosen words, phrases and entity names that allows them to reliably produce an interpretation that can be translated into SPARQL.

Dealing with Semantic Heterogeneity Issues on the Web

This work presents an approach to discover and represent, in a non-redundant way, the intended meaning of words in Web applications while taking into account the (often unstructured) context in which they appear.

Scalable Query-based Faceted Search on top of SPARQL Endpoints for Guided and Expressive Semantic Search

Scalewelis is a search system for the Web of Data like Sewelis that is scalable that is independent to data because it connects to SPARQL endpoints.

Generating SPARQL queries using templates

This paper presents an approach for constructing SPARQL queries based on user-supplied keywords using a set of predefined basic graph pattern templates for generating adequate interpretations of user queries that is completely agnostic of the underlying knowledge base and ontology schema.

Understanding SPARQL Endpoints through Targeted Exploration and Visualization

An integrated platform that supports the users to the querying, exploration and visualization of information contained in SPARQL endpoints is presented, offering an endpoint and data schema agnostic solution.

GoRelations: An Intuitive Query System for DBpedia

The key contributions are the robust techniques, combining statistical association and semantic similarity, that map user terms to the most appropriate classes and properties used in the DBpedia Ontology.

PowerAqua: Fishing the Semantic Web

The design of a QA system, PowerAqua, designed to exploit semantic markup on the web to provide answers to questions posed in natural language, is described.

Cross ontology query answering on the semantic web: an initial evaluation

It is shown that, despite the problems related to the noisy and incomplete conceptualizations, which can be found on the Semantic Web, good results can already be obtained.

Semantic Search Meets the Web

A novel semantic search system that provides the user with the capability to query Semantic Web information using natural language by means of an ontology-based Question Answering (QA) system and complements the specific answers retrieved during the QA process with a ranked list of documents from the Web.

Can we ever catch up with the Web?

The Semantic Web is about to grow up. By efforts such as the Linking Open Data initiative, we finally find ourselves at the edge of a Web of Data becoming reality. Standards such as OWL 2, RIF and…

Scaling Up Question-Answering to Linked Data

The issues and lessons learned from the experience of integrating PowerAqua as a front-end for DBpedia and a subset of Linked Data sources are discussed and extrapolated to a variety of end-user applications that wish to scale, open up, exploit and re-use what possibly is the greatest wealth of data about everything in the history of Artificial Intelligence.

ERDF: Live Discovery for the Web of Data

eRDF is an infrastructure for exploring the Web of Data through evolutionary querying that makes significant steps in these four areas: exploration, live-access, decentralisation and robustness.

FABilT – finding answers in a billion triples

It is shown here how most of the datasets provided for the challenge were indexed, thus obtaining an infrastructure which supports the exploration of these datasets and makes them available to any Watson-based application.

Reflections on five years of evaluating semantic search systems

It is concluded that the growth of the semantic web led to an improvement in the available resources and the consequent robustness of performance assessments, and proposes two directions for continuing evaluation work: the development of extensible evaluation benchmarks and the use of logging parameters for evaluating individual components of search systems.

PANTO: A Portable Natural Language Interface to Ontologies

PANTO is presented, a Portable nAtural laNguage inTerface to Ontologies, which accepts generic natural language queries and outputs SPARQL queries, and adopts a triple-based data model to interpret the parse trees output by an off-the-shelf parser.

How Useful Are Natural Language Interfaces to the Semantic Web for Casual End-Users?

The results of the study confirm that NLIs are useful for querying Semantic Web data and introduce four interfaces each allowing a different query language and present a usability study benchmarking these interfaces.
