However, most of the proposed models focus on either traditional document retrieval or the use of linked data for finding relevant information. We believe neither of these two types of information resources can offer sufficient support for complex search tasks on their own. We propose that a hybrid approach that combines the coherent content of text with the organized structure of graphs should be taken to better support information finding and sense making. Currently, there is limited insight into the types of information seeking activities performed when a knowledge graph is combined with document retrieval to support exploratory search. This paper describes a general framework that provides the first step towards examining users' exploratory search behaviour when interacting with knowledge graphs and their corresponding documents. We conducted a user study that suggests searchers perform different information seeking activities for a complex search task compared with a simple search task. These findings provide insights that can be used to inform the design of a new search framework, which enables more effective information finding and analysis.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"46 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":"124694290","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}

The results showed that the associations of dwell time in book pages and in many metadata types, and novels' interest grading were non-linear. Most time was used for assessing a somewhat interesting novel compared to a non-interesting or very interesting one. Therefore, the binary classification of interest grading hides and over-emphasizes the contribution of \"somewhat interesting\" category in modeling interest by dwell time in book pages or metadata. Non-linear regression models showed that the explanatory power was greater in a three-level classification of interest grading compared to a binary classification.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"41 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":"132662371","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}

Information needs of usability professionals in these organizations are diverse, and involve both qualitative findings and quantitative data from diverse research methods and sources. Therefore, usability specialists need support for organizing, retrieving, assessing, and analyzing the internal results of usability research. This paper focuses on a method used to evaluate a prototype of a faceted retrieval tool that specifically supports usability specialists accessing a collection of usability results. The evaluation (n=11) was conducted using a primarily qualitative, scenario-based approach. Because of this, it was possible to direct evaluation towards conceptual issues instead of examining details of the surface of the interface. In addition, a survey collected answers to standardized items on the usefulness and ease of use of the system in combination with more domain specific questions. Together, these results provide a valid foundation for the assessment of the usefulness and the relative priority of features.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"3 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":"123510974","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}

In this paper, we investigate the differences between children and adults in terms of usability and perception of targeted search engines, i.e. search engines designed specifically for that audience. To this end, an eye-tracking study was conducted to compare children's and adults' search behavior and perception of search interface elements on search engine results pages (SERPs) during an informational and a navigational search with a standard search engine and a search engine for children. We identified differences in the information-seeking behavior and perception of search engines SERPs between children and adults. Based on these findings we propose criteria on how to design search user interfaces that are more appropriate for children.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"5 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":"129554827","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}

In this paper we present initial analyses of a large-scale survey (n=606) to understand Personal Information Management (PIM) practices with social networking and microblogging systems, and Twitter in particular. Our results indicate that re-finding information in tweets is a common Twitter activity and can be frustrating. Using questionnaire responses, we investigate the influence of several factors, including how the user tends to preserve tweets of interest, and the level of frustration involved in re-finding such tweets when they are required later.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"29 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":"131432227","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}

{"title":"Engaging users with situational recommendations: challenges and results","authors":"F. Ricci","doi":"10.1145/2637002.2637005","DOIUrl":"https://doi.org/10.1145/2637002.2637005","url":null,"abstract":"Recommender Systems are popular tools that automatically compute personalised suggestions for items that are predicted to be interesting and useful to a user [24, 17]. For instance, in the music domain recommender systems support information search and discovery tasks by helping the user to find music tracks or artists that the user may not even know, but he will like [7, 15, 14]. Recommender systems accomplish their functionality by explicitly requesting users to enter their preferences and by tracking users' actions and behaviours, which implicitly signal users' preferences. Then, they aggregate these observation data and build predictive models of the users' future interests. Several techniques have been proposed to model user preferences and generate recommendations for them. But, ultimately, most of the implemented systems use content-, collaborative- or social-based approaches, or even more often, hybrid combinations of these three basic approaches [6]. In addition to long-term interests, which are normally acquired and modelled in RSs, other session specific factors do influence the user's response to the suggested items and therefore should be taken into consideration. These factors include: the ephemeral needs of the users [21, 19], their decision biases [8, 25], the context of the search [10, 18] and the context of items' usage [1]. However, appropriately modeling the user's preferences and behaviour in the possible various and diverse situational contexts and reasoning upon them in order to identify useful, convincing, diverse and relevant recommendations is still challenging. Major technical and practical difficulties must yet to be solved. First of all, one should parsimoniously narrow down the various types and the number of contextual dimensions that the system should model to those that actually influence the user decision making processes [2, 23]. Then, it is important to understand the dynamics of the impact of such contextual dimensions on the user preferences and the decision-making process [8]. This impact is strongly coupled with the full interaction design of the system [5, 16]. Moreover, it is important to implement technical solutions that enable the system to continuously acquire context-dependent user evaluations (e.g., ratings) for the suggested items, during the full life cycle of the system [20, 11, 12, 22]. Finally, one must embed the contextual dimensions and leverage the acquired data in a recommendation computational model [3, 9], while dealing with the typically very limited knowledge of the system for the users, the items and the contextual situations [4, 13]. These topics will be illustrated in the talk, making examples taken from the recommender systems that we have developed in the tourism and music domains.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"13 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":"132021123","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}

Users are provided different means to access and select the available sights, events and other points of interest (POIs): Via a hybrid recommender system, via browsing by sight category, via searching over descriptions of POIs or via browsing on a map. Based on user's selection a route planner for time-constrained activities generates route suggestions taking additional constraints for public transport connections into account. A novelty of the implemented approach compared to existing solutions for tourists is that the user retains full control over the tour by diverse interaction possibilities: Before route generation different means for selecting POIs are provided, during route generation multiple route variants are suggested and after route generation users are able to directly edit any detail at any time, even if there are existing constraints that hinder the direct execution of an edit operation. Moreover, recommender, planner and editing are closely interconnected: Recommendations are used by the planner to fill-up unavoidable gaps. This may also be initiated manually during editing where also parts of the planner are involved to permit only those edits that keep the route feasible. The app is currently tailored to the city of Nuremberg but can be extended for other cities as well.","PeriodicalId":447867,"journal":{"name":"Proceedings of the 5th Information Interaction in Context Symposium","volume":"49 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":"131293440","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}
