This paper describes the collaborative participation of Dublin City University and Trinity College Dublin in LogCLEF 2010. Two sets of experiments were conducted. First, different aspects of the TEL query logs were analysed after extracting user sessions of consecutive queries on a topic. The relation between the queries and their length (number of terms) and position (first query or further re...

The database usability experience has shown that visual query languages tend to be superior to textual languages in many aspects. By applying this principle in the context of ontologies, we present GLOO, a graphical query language for OWL-DL ontologies. GLOO maps diagrammatic queries to DL based query languages such as nRQL, which is offered by the OWL-DL reasoner Racer. GLOO hides the complexi...

In this paper, we propose SPBERT, a transformer-based language model pre-trained on massive SPARQL query logs. By incorporating masked modeling objectives and the word structural objective, SPBERT can learn general-purpose representations in both natural language. We investigate how encoder-decoder architecture be adapted for Knowledge-based QA corpora. conduct exhaustive experiments two additi...

This review presents various perspectives on converting user keywords into a formal query. Without understanding the dataset’s underlying structure, how can input text-based query and then convert this text semantic protocol resource description framework language (SPARQL) that deals with (RDF) knowledge base? The may not know structure syntax of SPARQL, sophisticated tool for web (SEW) its vas...

Abstract Information access to bibliographic metadata needs be uncomplicated, as users may not benefit from complex and potentially richer data that difficult obtain. Sophisticated research questions including aggregations could answered with SQL queries. However, this comes the cost of high complexity, which requires for a level expertise even trained programmers. A domain-specific query langu...

In a large heterogeneous distributed system spanning administrative domains such as a DataGrid, it is often desirable to maintain and query dynamic and timely information about active participants such as services, resources and user communities. This paper develops a suitable database and query model as well as a generic and dynamic data model for such database systems. Unlike in the relationa...
