Natürlichsprachliche und dialogorientiere Unterstützung bei der Objektsuche (VACOS 2) (VACOS 2)
LeaderDr. Dagmar Kern
The VACOS project aims to provide better support for searchers with
vague information needs formulated in natural language. We consider two
use cases: product search and research data search. In the first phase
of the project, our human-centered development process focused on
analyzing the user context, creating datasets with natural language
information needs, enriching datasets with topical and natural language
attributes, and developing prototypes for object search. The results of
the first project phase have shown the necessity to searchers not only
during the initial search process but also to explain search results and
their relation to the formulated search request. Therefore, concepts of
the research areas "Conversational Search" and "Explainable Search"
will be used in the second project phase. First, object metadata will be
enriched to generate object representations that better match
information needs formulated in natural language. Based on this,
mixed-initiative natural language search dialogues will be developed.
For the presentation of search results, various representation forms
will be investigated, focusing on vagueness and explainability. Single
result items will be explained with respect to the formulated search
request as well as in comparison to other found objects. In the context
of this proposed project, the prototypes developed in the first project
phase will be extended by new dialog and explanation components.
Human-centered evaluations will be conducted to examine natural language
and conversational supports for object search.
