Bridging memory-based collaborative filtering and text retrieval

Alejandro Bellogín, Jun Wang, Pablo Castells
2012 Information retrieval (Boston)  
In this regard, we propose a unified formulation under a common notational framework for memory-based collaborative filtering, and a technique to use any text retrieval weighting function with collaborative  ...  Specifically, major collaborative filtering algorithms, such as the memory-based, essentially calculate the dot product between the user vector (as the query vector in text retrieval) and the item rating  ...  Acknowledgements This work is supported by the Spanish Government (TIN2011-28538-C02-01) and the Regional Government of Madrid (S2009TIC-1542).  ...

A Recommender Agent for Software Libraries: An Evaluation of Memory-Based and Model-Based Collaborative Filtering

Frank McCarey, Mel Cinneide, Nicholas Kushmerick
2006 2006 IEEE/WIC/ACM International Conference on Intelligent Agent Technology  
In this paper we detail our RASCAL agent and describe two recommendation techniques; namely Model-Based and Memory-Based Collaborative Filtering.  ...  We are interested in producing a scalable and efficient realtime recommender and thus ideally would favor a Model-Based approach.  ...  With this mind we will investigate, compare and evaluate two CF algorithms in this paper, memory-based and model-based collaborative filtering.  ...

A critical assessment of hypertext systems

G. Fischer, S. Weyer, W. P. Jones, A. C. Kay, W. Kintsch
1988 Proceedings of the SIGCHI conference on Human factors in computing systems - CHI '88  
Rather than thinking of the system as containing information, think of it as an environment for descriptions and programs.  ...  Rather than thinking of the system as a passive entity on which the author performs neural surgery to add new components and connections, think of it as an active partner --a hyperknowledge assistant.  ...  computer-based information retrieval systems (the ME system adopts a network approach and actively models the user's own memory for the files of a personal directory.)  ...
