Verbesserung von Query Suggestions für seltene Queries auf facettierten Dokumenten. i
In this thesis it was further assumed that the user of the information retrieval system always searches for one specific document - leading to uniformly distributed queries. Under these constraints it was tried to exploit the structure of the faceted documents to provide helpful query suggestions. In addition to theoretical exploration of such improvements a custom datastructure was developed to efficiently provide interactive query suggestions. Evaluation of the developed query suggestion algorithms was done on multiple document collections by comparing them to a baseline algorithm that reduces faceted documents to single facet documents. Results are promising as the final version of the new query suggestion algorithm consistently outperformed the baseline.
Motivation for and potential application of this work can be found in call centers for customer support. For call center employees it is crucial to quickly locate relevant customer information - information that is available in structured form (and can thus easily be transformed into faceted documents).
