Provenance Querying for End-Users: A Drug Resistance Case Study [chapter]

Bartosz Baliś, Marian Bubak, Michal Pelczar, Jakub Wach
2008 Lecture Notes in Computer Science  
We also describe the process of ontology-based query construction and evaluation.  ...  This model enables query construction in an end-user oriented manner, i.e. by using terms of the scientific domain familiar to researchers, instead of complex query languages.  ...  Ontologies as a model for provenance proved to be an adequate inter-lingua between: (1) end users who use ontologies as a query language while interacting with a graphical user interface; (2) query tools  ...

How Ontology Can be Used to Improve Semantic Information Retrieval: The AnimSe Finder Tool

Abdelkrim Bouramoul, Med-Khireddine Kholladi, Bich-Lien Doan
2011 International Journal of Computer Applications  
This ontology is used at two different stages: First, for the semantic indexing of documents, in this stage the representative concepts of each document are selected by a projection of the ontology on  ...  In this paper, we propose a new approach for locating and retrieving documents; the search process is guided by the 'AnimOnto' domain ontology that we have constructed for this purpose.  ...  It takes as input a set of 25 queries posed by users in natural language.  ...

Ontology Based Natural Language Queries Transformation into SPARQL Queries

Majid Askar, Alsayed Algergawy, Taysir Hassan A. Soliman, Birgitta König-Ries, Adel A. Sewisy
2020 Baltic Journal of Modern Computing  
In the OBDA scheme, normally formal query languages, such as SPARQL, are used to represent the user questions, which limits end users from defining their requests.  ...  The proposed approach makes use of the capabilities of natural language processing and the semantic information embedded in the domain ontology.  ...  Proposed translator evaluation To test and evaluate the proposed tool, we will start with simple queries as a test for the prototype.  ...

SPARQL Query Builders: Overview and Comparison

Pavel Grafkin, Mikhail Mironov, Michael Fellmann, Birger Lantow, Kurt Sandkuhl, Alexander V. Smirnov
2016 Business Informatics Research  
The SPARQL query language has been proposed as a simple language for querying graph-structured data on the Semantic Web. However, users have to write queries that must conform to the SPARQL syntax.  ...  This requirement might be alleviated using a SPARQL query builder that suggests relevant parts of the query. But, up to now, only a few basic comparisons of such tools exist.  ...  The work has been partially supported by the Government of Russian Federation, Grant 074-U01.  ...

Ontology-based end-user visual query formulation: Why, what, who, how, and which?

Ahmet Soylu, Martin Giese, Ernesto Jimenez-Ruiz, Evgeny Kharlamov, Dmitriy Zheleznyakov, Ian Horrocks
2016 Universal Access in the Information Society  
An ontology is more promising than the logical schema of the underlying data for guiding users in formulating queries, since it provides a richer vocabulary closer to the users' understanding.  ...  This article presents and argues for ontology-based visual query formulation for end users; discusses its feasibility in terms of ontology-based data access, which virtualises legacy relational databases  ...  That is, a) a visual query formulation tool should primarily span the types of information needs and ontology constructs needed by users in their context; and b) the inclusion criteria should be the user  ...

Techniques of Ontology and its Usage in Indian Languages - A Review

Rajveer Kaur, Saurabh Sharma
2015 International Journal of Computer Applications  
It is hereby concluded from the review that in Indian languages usage of ontology is very less because of the challenges to build ontology for minority languages.  ...  This paper review has been carried out/done on the usage of different ontology building approaches in natural language processing and their usage on Indian languages.  ...  The result shows that users can solve each query faster when using OntoGraf as compare to two other tools such as OWL 2 Query and DL query.  ...

A Systematic RDF-based Approach for Structuring Government Open Data to Enhance Accessibility

Wilson Ambale, Isaiah Mulang, Andrew Mwaura
2018 International Journal of Computer Applications  
Software evaluation metrics (precision, recall, and f-measure) for retrieval systems was employed as the evaluation approach.  ...  This paper details the systematic steps followed from data selection to the development of an ontology and user interfacing modes of access using a case study of the Kenyan government open data portal.  ...  For instance, with NLP, a sentence such as "projects in Nairobi county with title construction can be used to construct a query.  ...

Design and Development of an Ontology based Personal Web Search Engine

T. Sakthi Priya, P. Revathy, T. Pradeesh, C.R. Rene Robin
2012 Procedia Technology - Elsevier  
This search engine is evaluated by getting feedback from three kinds of users. The results show that this ontology model is successful.  ...  As a model for knowledge description and formalization, ontologies are widely used to represent user profiles in personalized web information gathering.  ...  Acknowledgement: The authors thank the CEO and the Principal of Jerusalem College of Engineering, Chennai for the infrastructure provided to complete this project work.  ...

OntoDas – a tool for facilitating the construction of complex queries to the Gene Ontology

Kieran O'Neill, Alexander Garcia, Anita Schwegmann, Rafael C Jimenez, Dan Jacobson, Henning Hermjakob
2008 BMC Bioinformatics  
Ontologies such as the Gene Ontology can enable the construction of complex queries over biological information in a conceptual way, however existing systems to do this are too technical.  ...  Results: OntoDas is a web-based tool that uses information visualisation techniques to provide an intuitive, interactive environment for constructing ontology-based queries against the Gene Ontology Database  ...  and the National Bioinformatics Network, both of South Africa.  ...

Position paper

Harith Alani
2006 Proceedings of the 15th international conference on World Wide Web - WWW '06  
One of the main hurdles towards a wide endorsement of ontologies is the high cost of constructing them.  ...  This paper presents a fresh view on constructing ontologies automatically, by identifying, ranking, and merging fragments of online ontologies.  ...  The purpose here is to avoid reinventing the wheel by provide users with a tool to help them gather and learn from existing domain knowledge representations, thus bootstrapping their ontology construction  ...
