How concept maps change if a user does search or not?

Yuka Egusa, Masao Takaku, Hitomi Saito
2014 Proceedings of the 5th Information Interaction in Context Symposium on - IIiX '14  
In this study, we have compared differences between concept maps created before and after a search condition and a nonsearch condition to reveal whether these changes are due to searching.  ...  Previous studies have shown that a concept map can capture changes in the user knowledge structure during a search.  ...  We use a concept map to evaluate the knowledge users acquire and investigate how their knowledge structure changes as a result of searching for information on the Web.  ...

Knowledge Pattern Extraction and Their Usage in Exploratory Search [chapter]

Andrea Giovanni Nuzzolese
2012 Lecture Notes in Computer Science  
This Ph.D. work is aimed at developing methods for extracting KPs from the Web and at applying KPs to exploratory search tasks.  ...  Knowledge interaction in Web context is a challenging problem. For instance, it requires to deal with complex structures able to filter knowledge by drawing a meaningful context boundary around data.  ...  A comparison between an exploratory search application based on KPs and other existing exploratory search applications will be used for evaluating the effectiveness of KPs in exploratory search tasks.  ...

Benchmarking the Effectiveness of Associating Chains of Links for Exploratory Semantic Search

Laurens De Vocht, Selver Softic, Ruben Verborgh, Erik Mannens, Martin Ebner, Rik Van de Walle
2015 International Semantic Web Conference  
However, in an exploratory search scenario, the dynamics of the intermediary links that could lead to potentially relevant discoveries are not to be neglected.  ...  If we could benchmark how effective retrieving chains of links from these sources is, we can motivate why they are a reliable addition for exploratory search interfaces.  ...  Acknowledgments The research activities that have been described in this paper were funded by Ghent University, iMinds (Interdisciplinary institute for Technology) a research institute founded by the Flemish  ...

An Exploratory Search User Interface Concept Supporting Vague Querying and a Novel Result Representation

Timo Lüddecke, Markus Jüttner, Marcus Nitsche, Andreas Nürnberger
2014 iConference  
Therefore, we propose a search user interface concept that supports users in modelling their uncertainty in a comfortable way, foster exploratory search and provide a compact yet informative representation  ...  The results indicate a good usability of the concept and show that even this novel concept meets user's expectations.  ...  Acknowledgement We thank the flickr users tjstaab, freakgirl, lovebuzz, Kirti Poddar and jeff ro for releasing their images under a creative commons licence.  ...

A closer look at creativity as search

Graeme Ritchie
2012 International Conference on Computational Creativity  
Several papers by Wiggins (building on ideas by Boden) have outlined a view of creative concept generation as a very general search process, but that formalisation has not been developed much in the past  ...  Also, there are some aspects where clarification or spelling out of details would be useful.  ...  Acknowledgments The author is very grateful to Geraint Wiggins for detailed discussions of this material, and for comments on an draft of this paper.  ...

Towards Supporting Exploratory Search over the Arabic Web Content: The Case of ArabXplore

Al-Agha Iyad, Abed Ahmed
2020 Journal of Information Technology Management  
In this research, we propose a fully automated approach that aims to support exploratory search over the Arabic web content.  ...  Several efforts have been proposed to support exploratory search on the web by using query expansion, faceted search, or supplementary information extracted from external knowledge resources.  ...  Finally, top ranked entities and the links between them are visualized in a concept map-like graph and presented to the user.  ...
