How query cost affects search behavior

Leif Azzopardi, Diane Kelly, Kathy Brennan
2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
We investigate how the cost associated with querying in the context of information retrieval affects how users interact with a search system.  ...  cost required to query: Structured (high cost), Standard (medium cost) and Query Suggestion (low cost).  ...  CONCLUSIONS AND FUTURE WORK In this paper, we investigated how query cost affects search behavior.  ...

Building Economic Models of Human Computer Interaction

Leif Azzopardi, Guido Zuccon
2019 Extended Abstracts of the 2019 CHI Conference on Human Factors in Computing Systems - CHI '19  
By using economics models it is possible to reason about interaction and make predictions about how changes to the system will affect performance and behavior.  ...  As a case study, we demonstrate how various interactions with search and recommender applications can be modeled, before concluding the day with a hands-on modeling session using example and participant  ...  For example, how much more benefit/satisfaction a user receives from the interactions which comes at a cost, such as the trade-off between the length of a query and the performance of the query, or the  ...

An Analysis of Theories of Search and Search Behavior

Leif Azzopardi, Guido Zuccon
2015 Proceedings of the 2015 International Conference on Theory of Information Retrieval - ICTIR '15  
Theories of search and search behavior can be used to glean insights and generate hypotheses about how people interact with retrieval systems.  ...  While each approach takes a different perspective on modeling searcher interactions, we show that under certain assumptions, they lead to similar hypotheses regarding search behavior.  ...  However, the model does not provide an indication of how long the searcher will stay in a particular patch or how the time to reach a patch will affect their behavior.  ...

Beyond Query-Oriented Highlighting: Investigating the Effect of Snippet Text Highlighting in Search User Behavior

Hui Zhang
2018 Computational Intelligence and Neuroscience  
In this paper, we try to find out whether the default strategy of highlighting query terms employed by most commercial search engines is the best for search users.  ...  Snippet usually serves as a query-dependent summary of its corresponding landing page and is therefore treated as one of the most important factors in search interaction process.  ...  However, which kind of extraterms besides query terms should be highlighted and how this kind of revised highlighting strategy changes user behavior still remain uninvestigated as far as we know. e Query  ...

Time drives interaction

Feza Baskaya, Heikki Keskustalo, Kalervo Järvelin
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
We study the limits of effectiveness of diverse interactive searching strategies in two searching environments (the scenarios) under overall cost constraints.  ...  Furthermore, we will also contrast the proposed evaluation approach with the traditional one, rank based evaluation, and show how the latter may hide essential factors that affect users' performance and  ...  INTRODUCTION Interaction through search interface and environment greatly affects the user behavior, user experience, and user performance.  ...

Does Vertical Bring more Satisfaction?

Ye Chen, Yiqun Liu, Ke Zhou, Meng Wang, Min Zhang, Shaoping Ma
2015 Proceedings of the 24th ACM International on Conference on Information and Knowledge Management - CIKM '15  
In this paper, we carry out a lab-based user study with specifically designed SERPs to determine how verticals with different qualities and presentation styles affect search satisfaction.  ...  Mouse click-through / movement data and eye movement information are also collected such that we can investigate the influence of vertical results from the perspectives of both benefit and cost.  ...  Effect of Verticals on Search Benefit and Cost In this section, we investigate how verticals affect search satisfaction following the benefit-cost framework.  ...

How Random Decisions Affect Selective Distributed Search

Zhuyun Dai, Yubin Kim, Jamie Callan
2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
These random components make selective search non-deterministic. This paper studies how these random components affect experimental results.  ...  Selective distributed search is a retrieval architecture that reduces search costs by partitioning a corpus into topical shards such that only a few shards need to be searched for each query.  ...  Variability for Query Sets The first experiment examined how random decisions affect the 'average case' metrics typically reported in research papers.  ...

Teemu Pääkkönen, Jaana Kekäläinen, Heikki Keskustalo, Leif Azzopardi, David Maxwell, Kalervo Järvelin
2017 Information retrieval (Boston)  
Abstract A searcher's interaction with a retrieval system consists of actions such as query formulation, search result list interaction and document interaction.  ...  To this end, we run a series of simulations grounded by real world behavioral data to show how accurate and responsive the model is to various experimental conditions under which the data were produced  ...  5 ) as follows. • Action costs Query delays did not greatly affect query formulation cost compared to the baseline (average cost 8.4 s) whereas the other delay conditions increased it (DD 9.3 s; QDD 10.0  ...

The Impact of Smartphones, Barcode Scanning, and Location-based Services on Consumers' Search Behavior

Stephan Daurer, Dominik Molitor, Martin Spann, Puneet Manchanda
2013 International Conference on Information Systems  
Combining context-specific information with consumer search data allows us to measure how consumers search on the mobile Internet.  ...  We expect that our findings will give marketers a better understanding of consumers' search behavior and thus help companies to proactively target them with marketing programs in order to acquire "search  ...  Finally, we want to use our modeling approach to document how consumers react to the search results and how individual search behavior using location-based barcode scanning changes over time.  ...

2022 arXiv   pre-print
We challenge existing query-based ontology fault localization methods wrt. assumptions they make, criteria they optimize, and interaction means they use.  ...  We find that their efficiency depends largely on the behavior of the interacting expert, that performed calculations can be inefficient or imprecise, and that used optimization criteria are often not fully  ...  , (F2) the expert behavior (how will the expert answer queries?), (F3) the criterion to be optimized (how to measure the expert's effort?)  ...
