Do Hard Topics Exist? A Statistical Analysis

J. Shane Culpepper, Guglielmo Faggioli, Nicola Ferro, Oren Kurland
2021 Italian Information Retrieval Workshop  
Recently there has been renewed interest in the notion of "query variations" which are essentially multiple user formulations for an information need.  ...  However, all of these previous studies assume that a topic or information need is represented by a single query. In reality, users routinely reformulate queries to satisfy an information need.  ...  This is empirical evidence that topic difficulty is not an intrinsic property of an information need -meaning that query formulation based on a corpus and retrieval system, can be combined to sort topics  ...

Aiming for user experience in information retrieval

Frans van der Sluis, Betsy. van Dijk, Egon L. van den Broek
2010 Proceeding of the 33rd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '10  
Hence, we hypothesize that solving an information need is fostered with an enhanced UX.  ...  The multi-faceted notion of relevance pleas for a human-centered approach. Essentially, an IR system should solve the information need of its user, with its user.  ...  Acknowledgment This work was part of the PuppyIR project, which is supported by a grant of the 7th Framework ICT Programme (FP7-ICT-2007-3) of the European Union.  ...

On the role of logic in information retrieval

Fabrizio Sebastiani
1998 Information Processing & Management  
What are the guidelines that we should follow when we w ant to build one, and how m uch can we depart from these guidelines and still claim to have a logical model of IR?  ...  We h a v e been motivated to write this note from our dissatisfaction with the fact that there seem to be many competing, incompatible views of what a logical model of IR should consist of; we think some  ...  of this paper.  ...

they have a constant probability of advancing from one item in the result page to the next.  ...  That is, we wish to develop mechanisms that, based on the query alone, can be used to adjust system evaluations so that the experience of the user of the system is better captured in the system's effectiveness  ...  We thank Xiaolu Lu for assistance with the data collection and Bodo von Billerbeck for assistance with query log mining.  ...

Information Retrieval eXperience (IRX): Towards a Human-Centered Personalized Model of Relevance

Frans van der Sluis, Egon L. van den Broek, Betsy van Dijk
2010 2010 IEEE/WIC/ACM International Conference on Web Intelligence and Intelligent Agent Technology  
Based on a document's topicality, complexity, and emotional value, a model of relevance is proposed to influence user's IRX and, consequently, the synthesis and use of the retrieved information.  ...  As such, the proposed multi-dimensional IRX model is highly userdependent and determines document's relevance from a nontraditional human-centered, personalized perspective on IR.  ...  This work was part of the PuppyIR project, which is supported by a grant of the 7th Framework ICT Programme (FP7-ICT-2007-3) of the European Union.  ...

Professional's Information Link (PiL): a web-based asynchronous consultation service

William Hersh, Robin Miller, Daniel Olson, Lynetta Sacherek, Ping Cross
2002 Proceedings. AMIA Symposium  
Based on this notion and an information needs assessment, we developed the Professional's Information Link (PiL), a Web-based asynchronous consultation service to facilitate question answering between  ...  Despite the massive growth of on-line information resources, many clinicians still prefer to obtain information from other clinicians, particularly those to whom they refer patients.  ...  Acknowledgements PiL is funded by grants from the Eugene Garfield Foundation, OHSU Hospital, OHSU Medical Group, and Asante Health System.  ...

The Situatedness of the Seeker: Toward a Heideggerian Understanding of Information Seeking

David Tkach
2017 Canadian Journal of Academic Librarianship  
Instead, my analysis shows how Dasein permits a new conception of the information seeker, whose situatedness provides a new understanding of the activity of information seeking and the concept of information  ...  In my paper, I argue, first, that several representative models of information seeking are philosophically inadequate in light of the consequences of what Day calls the conduit metaphor.  ...  given or transmitted to the receptive seeker in order to satisfy an information need.  ...

The Tetris Model of Resolving Information Needs within the Information Seeking Process

Max L. Wilson
2017 Proceedings of the 2017 Conference on Conference Human Information Interaction and Retrieval - CHIIR '17  
The differing focus of the Tetris model is to better capture the temporal experience of searching, by removing the implied progression of left-to-right.  ...  , the purpose of which is to better represent the behaviours around the Human Computer Interaction with Information Retrieval, which are often confounded within stage-based models of the Information Seeking  ...  an information need.  ...

Relevance as a subjective and situational multidimensional concept

Carsten Eickhoff
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
Relevance is the central concept of information retrieval.  ...  (Novelty) describes the document's contribution to satisfying an information need with respect to the user's context. E.g., previous search results or general knowledge about the domain.  ...  The evaluation will be based on the notion of usefulness of shown results for users.  ...

Benjamin Piwowarski, Mounia Lalmas
2009 Lecture Notes in Computer Science  
We present how we propose to model the task of Structured IR (SIR) based on a QT inspired framework, with a focus on how to exploit user contextual information and user interaction in the search process  ...  Information Retrieval (IR) systems try to identify documents relevant to user queries, which are representations of user information needs.  ...  covers an information need.  ...

Dempster-Shafer's theory of evidence applied to structured documents

Mounia Lalmas
1997 Proceedings of the 20th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '97  
Taking into account the structure of a document allows the retrieval process to focus on those parts of the documents that are most relevant to an information need.  ...  Their aim was to express the model within a framework based on formal logics with associated theories. They developed the logical formalism of the model.  ...  Acknowledgement I would like to thank the Department of Computing Science at  ...

Focused and aggregated search: a perspective from natural language generation

Cécile Paris, Stephen Wan, Paul Thomas
2010 Information retrieval (Boston)  
We focus on exploring the parallels between aggregated search and natural language generation in the hope that the fields can be mutually informed, leading to further advances in the way search technologies  ...  These organisations can be motivated by linguistic theories that consider issues such as the role that the information plays to facilitate a task, and the relationships between different pieces of information  ...  the traditional search paradigm, a user enters a query to indicate an information need.  ...
