Based on the binary independence indexing model, we apply three new concepts for probabilistic document indexing from relevance feedback data: (cl 1990 ACM o-89791-408-2 90 0009 45 $1.50 ...
Acknowledgement We thank Keith van Rijsbergen for his constructive comments on an earlier version of this paper. ...

Our categorisation approach is based on a probabilistic description-oriented representation of web documents, and a probabilistic interpretation of the k-nearest neighbour classifier. ...
Experimental results show that (1) using an enhanced representation of web documents is crucial for an effective categorisation of web documents, and (2) a theoretical interpretation of the k-nearest neighbour ...
Our approach requires a test-bed of pre-categorised documents (for the learning phase). The creation of the test-bed is described in Section 4.1. ...

In this paper, we make a step forward to formulate an i-vector based language modeling (IVLM) framework for SDR. ...
techniques (such as probabilistic linear discriminative analysis, PLDA) can be readily and effectively used. ...
The results indicate that probabilistic approaches are a school of simple but powerful methods for SDR, and there are still potential research areas for non-probabilistic approaches. ...

A new approach regards IR as uncertain inference; here, imaging is used as a new technique for estimating the probabilistic parameters, and probabilistic inference networks support more complex forms of ...
For the estimation of these parameters, three different learning strategies are distinguished, namely query-related, document-related and description-related learning. ...
Document-related learning is orthogonal to the queryrelated strategy: probabilistic indexing models (see Section 3.1) collect relevance feedback data for a specific document d m from a set of queries Q ...

The probabilistic indexing weights required for any of these models can be provided by an application of the Darmstadt indexing approach (DIA) for indexing with descriptors from a controlled vocabu-Iary ...
In this model, the indexing weight of a descriptor in a document is an estimate of the probability of relevance of this document with respect to queries using this descriptor. ...
The DIA is a dictionary-based indexing approach for automatic indexing from document titles and abstracts, with a prescribed indexing vocabulary. ...
