My PhD thesis introduces a novel methodology that is named Search Interaction Optimization (SIO) and is used for designing, evaluating and optimizing search engine results pages (so-called SERPs). As a proof-of-concept of this new methodology, I've developed a corresponding SIO toolkit, which comprises a total of seven components1 (most of which have already been introduced in previous… Continue reading The Search Interaction Optimization Toolkit – The Essence of my PhD Thesis

INUIT: The Interface Usability Instrument
As one of the building blocks of my PhD thesis, I have developed a novel instrument for measuring the usability of web interfaces, which is simply called Inuit—the Interface Usability Instrument1. This was necessary because a usability instrument that is suited for the automatic methods for Search Interaction Optimization I have developed in my PhD… Continue reading INUIT: The Interface Usability Instrument

What is ›Usability‹?
Earlier this year, I submitted a research paper about a concept called usability-based split testing1 to a web engineering conference (Speicher et al., 2014). My evaluation involved a questionnaire that asked for ratings of different usability aspects—such as informativeness, readability etc.—of web interfaces. So obviously, I use the word “usability” in that paper a lot;… Continue reading What is ›Usability‹?
Survey: Search Engines – Perception, Usage & Expectations

With the help of this survey I hope to better understand how you perceive and use search engines and which expectations you have towards them. In particular, I focus on the use of search… Continue reading Survey: Search Engines – Perception, Usage & Expectations
Umfrage: Suchmaschinen – Wahrnehmung, Nutzung & Erwartungen

Es geht mir in dieser Umfrage vor allem darum, herauszufinden, wie ihr Suchmaschinen wahrnehmt und welche Erwartungen ihr an sie habt. Besonderer Fokus liegt auch auf der Nutzung mit Smartphones, Tablets und anderen Geräten, wie z. B. einer Nintendo Wii… Continue reading Umfrage: Suchmaschinen – Wahrnehmung, Nutzung & Erwartungen

Oder schon mal auf der Seite der Uni Würzburg versucht, herauszufinden, wie genau eine Bewerbung für den Bachelor in Wirtschaftswissenschaften abläuft? Nein? Ist auch eigentlich besser so, weil… Continue reading [offene Masterarbeit] Was that Page Pleasant to Use? Usability-Metriken in einer echten Suchmaschine

Recently, my post about motherfuckingwebsite.com was featured on the front page of Y Combinator's Hacker News. I was watching football with some friends when my WordPress app told me twice that my blog's stats "are exploding". Back at home, I checked my stats and noticed that I had almost 6,000 unique visitors and over 7,000 views… Continue reading How to do Power Law Regression in R, or What Happened When One of my Posts Made it to the Front Page of Hacker News
