It has been shown that simulated work tasks must be tailored toward the group of study participant to ensure that the depicted situations are realistic and interesting from the participants' point of view [3]. Specifically, we investigate what characterizes an effective simulated work task in a professional government setting and how to design workable tasks for the evaluation of in-house information systems such as a corporate Intranet. The findings reveal that the test participants adopt the tasks. To understand and apply the simulated work tasks, the participants draw on different types of experience and knowledge: Topical, related, structural, and common knowledge. The study also shows that the knowledge types identified are more important for successful retrieval of information than similarity of the simulated work tasks with the participants' daily work tasks.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"142 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115626315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We propose to model these properties as a priori probability that we integrate into language model. We evaluated the effectiveness of our approach on IMDb dataset containing 167438 resources and their social signals collected from several social networks. Our experimental results are statistically significant and show the interest of integrating social properties in a search model to enhance the information retrieval.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127071820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recommendations represent one such feature. Developments so far in this area indicate that non-personalized or item-level recommendations are most suited to the OPAC environment. Whilst a number of such systems have been developed and implemented, research has yet to investigate fully the impact of such recommendations on user performance, search behavior, and system perceptions. This paper presents the results of an exploratory laboratory-based study comparing user behavior in Amazon, which offers non-personalized recommendations, and WorldCat.org, which does not. An analysis of task performance and participant interactions with the systems reveals that the presence of non-personalized recommendations improves resource discovery, search efficiency, and perceived usability.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"15 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123598434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A user experiment was conducted. Participants were asked to search under two conditions: with time constraint (TC) and with no time constraint (NTC). The results showed that time constraint did not significantly influence participants' assessment of task difficulty, but significantly influenced users' search confidence and their evaluation of search performance. Particularly, participants were less confident and considered their search performance worse in TC than in NTC conditions. We also found users acquired more new knowledge and had more positive affective states after searching in NTC than in TC conditions. Interestingly, we found time constraints also affect participants' anticipation of time needed to complete the task; participants thought they would need significantly less time to complete the search task when they were given time constraints than without time constraints. These preliminary results suggested that time constraints had remarkable influence upon users' perception of search tasks and their search experience.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"91 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132704151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use data on the Web for work, leisure, and research, aided by various search systems, allowing us to find small needles in giant haystacks. Despite recent advances in personalization and contextualization, however, various types of tasks, ranging from simple lookup tasks to complex, exploratory and analytical ventures, are mainly supported in elementary, \"one-size-fits-all\" search interfaces. Web archives, keepers of our future cultural heritage, have gathered petabytes of valuable Web data, which characterize our times for future generations. Access to these archives, however, is surprisingly limited: online Web archives usually provide a URL-based Wayback Machine interface, sometimes extended with rudimentary search options. As a result of limited access, Web archives have not been widely used for research so far. For emerging research using Web archives, there is a need to move beyond URL-based and simple search access, towards providing support for complex (re)search tasks. In my thesis, I am exploring ways to move beyond the \"one-size-fits-all\" approach for search systems, and I work on systems which can support the flow of complex search, also in the context of archived Web data. Rich models of search and research can be incorporated into adaptive search systems, supporting search strategies in various stages of complex search tasks. Concretely, I look at the use case of the Humanities researcher, for which the large, Terabyte-scale Web archives can be a valuable addition to existing sources utilized to perform research.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127329152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional methods of collecting relevance labels rely on a fixed group of hired expert judges, who are trained to interpret user queries as accurately as possible and label documents accordingly. Human judges and the obtained relevance labels thus provide a critical link within the Cranfield style IR evaluation framework, where disagreement among judges and the impact of variable judgment sets on the final outcome of an evaluation is a well studied issue. There is also reported evidence that experiment outcomes can be affected by changes to the judging guidelines or changes in the judge population. Recently, the growing volume and diversity of the topics and documents to be judged is driving the increased adoption of crowdsourcing methods in IR evaluation, offering a viable alternative that scales with modest costs. In this model, relevance judgments are distributed online over a large population of humans, a crowd, facilitated, for example, by a crowdsourcing platform, such as Amazon's Mechanical Turk or Clickworker. Such platforms allow millions of anonymous crowd workers to be hired temporarily for micro-payments to complete so-called human intelligence tasks (HITs), such as labeling images or documents. Studies have shown that workers come from diverse backgrounds, work in a variety of different environments, and have different motivations. For example, users may turn to crowdsourcing as a way to make a living, to serve an altruistic or social purpose or simply to fill their time. They may become loyal crowd workers on one or more platforms, or they may leave after their first couple of encounters. Clearly, such a model is in stark contrast to the highly controlled methods that characterize the work of trained judges. For example, in a micro-task based crowdsourcing setup, worker training is usually minimal or non-existent. Furthermore, it is widely reported that labels provided by crowd workers can vary in quality, leading to noisy labels. Crowdsourcing can also suffer from undesirable worker behaviour and practices, e.g., dishonest behaviour or lack of expertise, that result in low quality contributions. While a range of quality assurance and control techniques have now been developed to reduce noise during or after task completion, little is known about the workers themselves and possible relationships between workers' characteristics, behaviour and the quality of their work. In this talk, I will review the findings of recent research that examines and compares trained judges and crowd workers hired to complete relevance assessment tasks of varying difficulty. The investigations include a range of aspects from how HIT design, judging instructions, worker demographics and charact","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"10 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123763817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
