• Abstract: Retrieval over knowledge graphs is usually performed using dedicated, complex query languages like SPARQL. We propose a novel system, Ontology and Semantic Exploration Toolkit (OnSET) that allows non-expert users to easily build queries with visual user guidance provided by topic modelling and semantic search throughout the application. OnSET allows users without any prior information about the ontology or networked knowledge to start exploring topics of interest over knowledge graphs, including the retrieval and detailed exploration of prototypical sub-graphs and their instances. Existing systems either focus on direct graph explorations or do not foster further exploration of the result set. We, however, provide a node-based editor that can extend on these missing properties of existing systems to support the search over big ontologies with sub-graph instances. Furthermore, OnSET combines efficient and open platforms to deploy the system on commodity hardware.

  We have developed a unique approach to data navigation that leans on geographical visualisation and hierarchically structured domain knowledge. Our approach uses natural language processing techniques to extract named entities from the underlying data and normalise them against relevant semantic domain references and navigational structures. This allows end-users to identify entities relevant to their needs and access extensive graph analytics.

  Traditional keyword-based search engines fall short in assisting users who may not be familiar with specific terminologies. We present a knowledge graph-based paper search engine for biomedical research to enhance the user experience. The system, dubbed DiscoverPath, employs Named Entity Recognition (NER) and part-of-speech (POS) tagging to extract terminologies and relationships from article abstracts to create a KG.
