Domain experts search differently than people with little or no domain knowledge. Previous research suggests that domain experts employ different search strategies and are more successful in finding what they are looking for than non-experts. In this paper we present a large-scale, longitudinal, log-based analysis of the effect of domain expertise on web search behavior in four different domains (medicine, finance, law, and computer science). We characterize the nature of the queries, search… Expand
The Impact of Technical Domain Expertise on Search Behavior and Task Outcome
TLDR
An online user study with searchers proficient in programming languages focuses on Java and Javascript, and finds that general expertise helped finding the correct answers, but the domain experts were more successful as they managed to detect better answers. Expand
How Does Domain Expertise Affect Users’ Search Interaction and Outcome in Exploratory Search?
TLDR
This work investigates the influence of domain expertise levels on the interaction and outcome of exploratory search in three different domains: environment, medicine, and politics, and identifies both domain-independent and domain-dependent effects on user behaviors and search outcomes. Expand
Predicting users' domain knowledge in information retrieval using multiple regression analysis of search behaviors
TLDR
This study examines whether user domain knowledge can be predicted from search behaviors by applying a regression modeling analysis method and identifies behavioral features that contribute most to a successful prediction model. Expand
The role of domain knowledge in document selection from search results
TLDR
Analysis of document selection behaviors of users with different levels of domain knowledge shows that users with high and low DK levels selected different sets of documents to view; those high in DK read more documents and gave higher relevance ratings for the viewed documents than those low in DK did. Expand
How does Domain Expertise Affect Users' Search Processes in Exploratory Searches?
TLDR
This position paper proposes to conduct a user study to investigate whether and how users’ domain expertise affect their search processes in exploratory searches. Expand
On the impact of domain expertise on query formulation, relevance assessment and retrieval performance in clinical settings
TLDR
The results show that medical domain expertise significantly influences the perception of relevance even among users with similar levels of expertise and reinforces the idea that a single ground truth does not exist, thereby leading to the variability of system rankings with respect to the level of users expertise. Expand
Exploratory information search by domain experts and novices
TLDR
Results from an experiment comparing search behavior of experts and novices when they searched using a tradition search engine and a social tagging system showed that experts relied more on their own domain knowledge to generate search queries, whileNovices were influenced more by social cues in the social tagged system. Expand
The role of domain knowledge in cognitive modeling of information search
TLDR
A cognitive model of information search is addressed which enables us to use two semantic spaces having a low (non-expert semantic space) and a high amount of medical and health related information to represent respectively low and high knowledge of users in this domain. Expand
How do users handle inconsistent information?: the effect of search expertise
TLDR
Investigating the effect of search expertise on search behavior and satisfaction criteria of users suggests that search non-experts tend to be less concerned about the consistency in their found answers, on the basis of which the design implications for making searchNon-Experts aware of the existence of inconsistent answers and helping them to search for supporting evidence for answers are discussed. Expand
The exploration of objective task difficulty and domain knowledge effects on users' query formulation
TLDR
The results showed that there was no significant difference between domain experts and novices in query similarity, but there existed an opposite pattern of task difficulty effects on query similarity for searchers with different domain knowledge levels. Expand

Important Cognitive Components of Domain-Specific Search Knowledge
TLDR
The study demonstrates the role of domain-specific search knowledge, and pinpoints its cognitive components, by observing information retrieval experts in the domains of healthcare and online shopping while they performed tasks within and outside their domains of expertise. Expand
How medical expertise influences web search interaction
TLDR
Findings from a log-based study into how medical domain experts search the Web for information related to their expertise, as compared with non-experts are presented. Expand
The effects of expertise and feedback on search term selection and subsequent learning: Research Articles
TLDR
The effects of domain knowledge and feedback on search term selection and reformation are investigated and differences between experts and novices as they generate search terms over 10 successive trials and under two feedback conditions are explored. Expand
The effects of expertise and feedback on search term selection and subsequent learning
TLDR
The effects of domain knowledge and feedback on search term selection and reformation are investigated and differences between experts and novices as they generate search terms over 10 successive trials and under two feedback conditions are explored. Expand
Investigating the querying and browsing behavior of advanced search engine users
TLDR
The results show that there are marked differences in the queries, result clicks, post-query browsing, and search success of users the authors classify as advanced (based on their use of query operators), relative to those classified as non-advanced. Expand
Domain knowledge, search behaviour, and search effectiveness of engineering and science students: an exploratory study
TLDR
The level of domain knowledge seems to have an effect on search behaviour, but not on search effectiveness, and search behaviour does not seem to be related to search effectiveness. Expand
Knowledge in the head and on the web: using topic expertise to aid search
TLDR
The importance of background knowledge for effective searching on the Web is not well understood and a more complete theory-led understanding of these effects would assist workers in a whole range of Web-related professions. Expand
Web search behavior of Internet experts and newbies
TLDR
It is found that while successful search performance requires the combination of the two types of expertise, specific strategies directly related to Web experience or domain knowledge can be identified. Expand
Strategy hubs: Domain portals to help find comprehensive information
TLDR
A controlled experiment suggests that this approach can improve the ability of novice searchers in finding comprehensive and accurate information, when compared to general-purpose search engines and domain-specific portals. Expand
Investigating behavioral variability in web search
TLDR
A longitudinal log-based study that investigated variability in people's interaction behavior when engaged in search-related activities on the Web suggests that there are dramatic differences in variability in key aspects of the interaction within and between users, and between the search queries they submit.
