- Abstract
- This paper uses a mix of qualitative and quantitative methodology to analyse differences between Finnish and American web searchers (n=27 per country) in their choice of initial search strategies (direct address, subject directory and search engines) and their reasoning underlying these choices, with data gathered via a questionnaire. The paper looks at these differences for four types of questions with two variables: closed/open and predictable/unpredictable source of answer (n=16 questions per searcher; total n=864 questions). The paper found significant differences between the two groups' initial search strategies and for three of the four types of questions. The reasoning varied across countries and questions as well, with Finns mentioning fewer reasons although both groups mentioned in aggregate a total of 1,284 reasons in twenty-four reason categories. The reasoning indicated that both country groups considered not only question-related reasons but also source- and search-strategy related reasons in making their decision. The research raises questions about considering cultural differences in designing web search access mechanisms.

- Abstract
- Query reformulation is a key user behavior during Web search. Our research goal is to develop predictive models of query reformulation during Web searching. This article reports results from a study in which we automatically classified the query-reformulation patterns for 964,780 Web searching sessions, composed of 1,523,072 queries, to predict the next query reformulation. We employed an n-gram modeling approach to describe the probability of users transitioning from one query-reformulation state to another to predict their next state. We developed first-, second-, third-, and fourth-order models and evaluated each model for accuracy of prediction, coverage of the dataset, and complexity of the possible pattern set. The results show that Reformulation and Assistance account for approximately 45% of all query reformulations; furthermore, the results demonstrate that the first- and second-order models provide the best predictability, between 28 and 40% overall and higher than 70% for some patterns. Implications are that the n-gram approach can be used for improving searching systems and searching assistance.

- Abstract
- To better understand how individuals and groups derive satisfaction from information, it is important to identify the information source preferences they apply in information seeking and decision making. Four informal propositions drove the structure and underlying logic of this study, forming a preliminary outline of a theory of information source preference profiles and their influence an information satisfaction. This study employed Social Judgment Analysis (SJA) to identify the information judgment preferences held by professional groups for six selected information sources: word of mouth, expert oral advice, Internet, print news, nonfiction books, and radio/television news. The research was designed as an hypotheses-generating exploratory study employing a purposive sample (n = 90) and generated four empirically supported, testable hypotheses about user satisfaction with information sources. The SJA judgment functions revealed the influences of volume and polarity (i.e., positive versus negative information) an information satisfaction. By advancing the understanding of how information source preferences can be identified empirically and their influence an information satisfaction, this research reflects a first, small step toward understanding "satisficing." Satisficing behaviors result in early termination of information search processes when individuals, facing incomplete information, are sufficiently satisfied to assume risks and execute decisions.
