A Survey of Quantum Theory Inspired Approaches to Information Retrieval
Sagar Uprety, Dimitris Gkoumas, Dawei Song
Since 2004, researchers have been using the mathematical framework of Quantum Theory (QT) in Information Retrieval (IR). QT offers a generalized probability and logic framework. Su…
Quantum-like Structure in Multidimensional Relevance Judgements
Sagar Uprety, Prayag Tiwari, Shahram Dehdashti +4
A large number of studies in cognitive science have revealed that probabilistic outcomes of certain human decisions do not agree with the axioms of classical probability theory. Th…
Modelling Dynamic Interactions between Relevance Dimensions
Sagar Uprety, Shahram Dehdashti, Lauren Fell +2
Relevance is an underlying concept in the field of Information Science and Retrieval. It is a cognitive notion consisting of several different criteria or dimensions. Theoretical m…
Investigating Bell Inequalities for Multidimensional Relevance Judgments in Information Retrieval
Sagar Uprety, Dimitris Gkoumas, Dawei Song
Relevance judgment in Information Retrieval is influenced by multiple factors. These include not only the topicality of the documents but also other user oriented factors like trus…
Investigating non-classical correlations between decision fused multi-modal documents
Dimitris Gkoumas, Sagar Uprety, Dawei Song
Correlation has been widely used to facilitate various information retrieval methods such as query expansion, relevance feedback, document clustering, and multi-modal fusion. Espec…
Investigating Order Effects in Multidimensional Relevance Judgment using Query Logs
Sagar Uprety, Dawei Song
There is a growing body of research which has investigated relevance judgment in IR being influenced by multiple factors or dimensions. At the same time, the Order Effects in seque…
Modeling Multidimensional User Relevance in IR using Vector Spaces
Sagar Uprety, Yi Su, Dawei Song +1
It has been shown that relevance judgment of documents is influenced by multiple factors beyond topicality. Some multidimensional user relevance models (MURM) proposed in literatur…
