Introduction

_ research project »VISEA - Visual Search Interfaces« _ focus: visual interfaces for product search _ use case: travel search + financial search

Problem: _ vague information need has to be transformed into a specific search query (Dörk et al. 2012)

Our Objective: _ supporting vague feelings and ideas in the process of information seeking

_ providing alternative visual approaches for product search besides the established keyword search paradigm

Motive-based Search

Motive: _ cause of search, specifies some general conditions _ influenced by emotions and interests of the user

Search Paradigms

TUNKELANG 2006:

Direct Search _ allows users to simply write queries in a text box

Navigational Search _ provide guidance through the use of taxonomies

Clemmer & Davis 2011:

General to Specific _ use abstract criteria to progressively narrow down the result set to the desired set of answers

Specific to General _ starts with an example _ can be generalized to find similar results

Visual Exploration System for Product Searches

Recommendation-based Search Approach: _ hides complex data strcuture of the search system _ leads to a small result set in a few steps

Analytical Approach: _ provides a deep insight into the data structure _ enables evaluation of the chosen product in comparison to the remaining information space

Seach by Example Approach: _ support users with little knowledge of the search domain _ goal: familiarizing with product features, finding of similar products

Recommendation-based Search Approach

‚getInspired‘ interface for travel search: triggers emotionally driven decisions

PRODUKTTYP:

PRODUKTGRUPPE: BONUSZERTIFIKAT

Bonus-Zerti�kate haben eine feste Laufzeit. Weiter wird ein Bonuszerti�kat durch zwei Param-eter bestimmt, die Barriere, auch Sicherheitslevel genannt, und das Bonuslevel. Abhängig von der Wahl dieser Parameter reagiert der Wert des Zerti�kates auf die Entwicklung seines Ba-siswertes.

Das Sicherheitslevel spielt eine wesentliche Rolle: Berührt oder durchbricht der Basiswert die Barriere während der Laufzeit auch nur ein einziges Mal, dann ändert sich der Charakter des Bonuszerti�kats vollständig: Es wird zu einem normalen Trackerzerti�kat und der Bonus ist un-widerru�ich verloren, auch wenn am Fälligkeitstag der Basiswert wieder über der Barriere liegt. Allerdings unterscheidet sich die Rendite eines Bonuszerti�kates von der eines Trackerzerti�-kates, da der Preis des Bonuszerti�kates um den Wert der Barrieroption über dem Preis eines entsprechenden Trackerzerti�kates liegt.

Conclusion & Future Work

_ search experience and speed in product search scenarios can be significantly improved by visually appealing interfaces

_ recommendation-based approach: good results in short time

_ analytical approach: better results, but requires more effort and time

challenges: _ management of a huge variety of different informati-on sources and formats

_ good balance between insights in the underlying data sources and a user-friendly, easily comprehensible interface
