A Guided Template-Based Question Answering System over Knowledge Graphs

Lukas Biermann, Sebastian Walter, Philipp Cimiano
2018 International Conference Knowledge Engineering and Knowledge Management  
For this, a template-based approach is used to generate all possible questions from a given RDF dataset using a number of templates.  ...  To remedy this, we present a new guided approach to QA that ensures that all questions that can be entered into the system also return a corresponding answer.  ...  This is accomplished by a template-based approach that matches basic graph patterns over the data and, using a lexicon, generates different variants of asking the same question.  ...

Knowledge-Based Legal Document Assembly [article]

Marko Marković, Stevan Gostojić
2020 arXiv   pre-print
This knowledgebase has two components - the formal knowledge of legal norms represented as a rule-base and the tacit knowledge represented by a document template.  ...  This paper proposes a knowledge-based legal document assembly method that uses a machine-readable representation of knowledge of legal professionals.  ...  It uses configuration created in the previous phase to guide a user through a question answering process. A user is asked a series of questions.  ...

Complex Knowledge Base Question Answering: A Survey [article]

Yunshi Lan, Gaole He, Jinhao Jiang, Jing Jiang, Wayne Xin Zhao, Ji-Rong Wen
2022 arXiv   pre-print
Knowledge base question answering (KBQA) aims to answer a question over a knowledge base (KB). Early studies mainly focused on answering simple questions over KBs and achieved great success.  ...  Therefore, in recent years, researchers propose a large number of novel methods, which looked into the challenges of answering complex questions.  ...  Among them, knowledge base question answering (KBQA) is a task that aims to answer natural language questions with KBs acting as its knowledge source.  ...
