Probabilistic models of information retrieval based on measuring the divergence from randomness
2002
ACM Transactions on Information Systems
Preserved Fulltext
We derive term-weighting models by measuring the divergence of the actual term distribution from that obtained under a random process. ...
We introduce and create a framework for deriving probabilistic models of Information Retrieval. The models are nonparametric models of IR obtained in the language model approach. ...
The probabilistic models of randomness are based on the term-independence assumption. ...

We used different theoretical retrieval models: probabilistic as InL2 (Divergence from Randomness model) and language model and tested their interpolated combination. ...
A combination of multiple information retrieval approaches is proposed for the purpose of book recommendation. In this paper, book recommendation is based on complex user's query. ...

The main goal of a retrieval model is to measure the degree of relevance of a document with respect to the given query. ...
Probabilistic models are widely used to measure the likelihood of relevance of a document by combining within document term frequency and term specificity in a formal way. ...
One of the widely used non-parametric probabilistic model is divergence from randomness (DFR) [1] based approaches, where the term weight is computed by measuring the divergence between a term distribution ...

On the other hand, we aimed at combining an often used probabilistic model, namely the Divergence From Randomness BM25 model (DFR BM25), with a monolingual translation-based model. ...
On the one hand, we intended to increase the precision of WSD by a heuristic-based combination of the annotations of the two WSD systems. ...

Current measures for assessing sample quality are too coarse grain to be informative. This paper outlines a measure of finer granularity based on probabilistic topic models of text. ...
Topics are both modelled from the collection and inferred in the sample using latent Dirichlet allocation. ...
In the following sections we outline a new approach for evaluating resource description quality based on probabilistic topical modelling. ...

Though the ranking algorithms have probabilistic roots, the ranking score often is not probabilistic, leading to unsafe programs from a probabilistic point of view. ...
In this paper, we describe the evolution of probabilistic Datalog to provide concepts required for modelling ranking algorithms. ...
We focus on TF-IDF, BM25, language modelling (LM), and divergence-from-randomness (DFR). The remainder of this paper is structured as follows. ...
