Intelligent SPARQL Query Generation for Natural Language Processing Systems
IEEE Access, 2021 Developing question answering (QA) systems that process natural language is a popular research topic. Conventionally, when QA systems receive a natural language question, they choose useful words or phrases based on their parts-of-speech (POS) tags.

Multiword Discourse Markers Across Languages: A Linguistic and Computational Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Discourse markers (DMs) are linguistic expressions that convey different semantic and pragmatic values, managing and organizing the structure of spoken and written discourses. They can be either single‐word or multiword expressions (MWE), made up of conjunctions, adverbs, and prepositional phrases.

Sparql-Ld: A Sparql Extension For Fetching And Querying Linked Data
Proceesings of the 14th International Semantic Web Conference - Demonstrations Track (ISWC'15), 2015 SPARQL is a standard query language for retrieving and manipulating RDF data. However, the majority of SPARQL implementations require the data to be available in advance, i.e., to exist in main memory or in a RDF repository (accessible through a SPARQL endpoint).

Efficient SPARQL Queries Generator for Question Answering Systems
IEEE Access, 2022 Much like traditional database querying, the question answering process in a Question Answering (QA) system involves converting a user’s question input into query grammar, querying the knowledge base through the query grammar, and finally ...

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models
Advanced Engineering Materials, Volume 27, Issue 8, April 2025.In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.
