Objectives

More and more knowledge is available electronically in a structured or
unstructured form over the World Wide Web (WWW). Such knowledge has
become a rich resource to answer our daily life questions and even
scientific questions posed by domain experts. Accordingly, it becomes a
necessity to develop tools that can (semi-)automatically answer
questions based on the large amount of available data.

Such challenges have been targeted separately over the last years by
different communities, including query answering in the Semantic Web
based on structured semantic data and question answering in Natural
Language Processing based on unstructured textual data. While the former
is powerful in representing complex questions and exploring background
knowledge (e.g., large biomedical ontologies), it is often difficult to
master, and such an advanced answering system cannot be used without a
specialized user interface. In contrast, the latter can handle natural
questions directly but can formulate constraints that cannot be
represented formally by query answering approaches due to the limited
expressiveness of formal languages. Besides it is not obvious how to
take into account the background and common sense knowledge needed to
obtain precise answers over structured data.

The objective of this workshop is to bring together researchers and
developers working on question/query answering systems over structured
or unstructured knowledge, and create a platform to grow potential
collaborations in this multidisciplinary task.

Topics of submissions include, but are not limited to:

- Text-based question answering
- Ontology-based query answering
- Hybrid reasoning based on both text and structured knowledge
- Information extraction over (un-)structured data
- Applications of question answering
- Domain-specific question answering
- Temporal event extraction from text
- Temporal reasoning for query answering
- Ontologies and knowledge graphs for question/query answering
- Biomedical text analysis for question/query answering
- Datasets combining structured and unstructured knowledge

Submissions

Papers for the workshop should be submitted in PDF format via EasyChair
at https://easychair.org/conferences/?conf=www2018satellites , selecting
the track “First International Workshop on Hybrid Question Answering
with Structured and Unstructured Knowledge”. Submitted papers must use
the new ACM format published in ACM guidelines
(http://www.acm.org/publications/proceedings-template), selecting the
generic “sigconf” sample. Submissions must not exceed 4-6 pages in
length. Papers must not have been previously published or be under
review at another workshop. However, we encourage submissions that
present summaries or highlights of work appearing elsewhere in longer
form. Accepted papers will be published in a companion volume of the
main proceedings of The Web Conference 2018.
