2010
Proceedings of the VLDB Endowment
Preserved Fulltext
There is a number of challenges in terms of collecting, modelling, representing, querying, indexing and mining uncertain data. ...
Managing, searching and mining uncertain data has achieved much attention in the database community recently due to new sensor technologies and new ways of collecting data. ...
This tutorial aims at providing a comprehensive view of the state-of-the-art research in probabilistic similarity search and probabilistic data mining for uncertain data. ...

On the other hand, models based on probabilistic indexing outperform the ranking procedures using search term weights. ...
The effect of probabilistic search term weighting on the improvement of retrieval quality has been demonstrated in various experiments described in the literature. ...
In a second series of experiments, models based on probabilistic indexing (that is, document term weighting) are tested and the results are compared with those of the search term weighting models. ...
