Do Hard Topics Exist? A Statistical Analysis
2021
Italian Information Retrieval Workshop
Preserved Fulltext
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 ...

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

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. ...
