Integration of probabilistic fact and text retrieval

Norbert Fuhr
1992 Proceedings of the 15th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '92  
In this paper, a model for combining text and fact retrieval is described. A query is a set of conditions, where a single condition is either a text or fact condition.  ...  These indexing weights are used in retrieval for a probabilistic ranking of objects basedon the retrieval-with-probabilistic-indexing (RPI) model, for which a new derivation is given here. 2  ...  command in order to show elements of the answer. 7 Conclusions and outlook In this paper, we have described a probabilistic approach for integrating text and fact retrieval.  ...

Probabilistic Modeling of Vague Conditions in Interactive Product Search

Alfred Sliwa
2019 BCS-IRSG Symposium on Future Directions in Information Access  
We argue that leveraging probabilistic modeling techniques and especially user-driven UI development can optimize the overall retrieval quality.  ...  However, many systems support retrieval of items fulfilling Boolean conditions so that only exact matching leads to the inclusion in the result list.  ...  In [3] probabilistic models are used to integrate text and fact retrieval where both text and fact conditions are treated similarly and vague but separately.  ...

Scalable DB+IR Technology: Processing Probabilistic Datalog with HySpirit

Ingo Frommholz, Thomas Roelleke
2016 Datenbank-Spektrum  
Making PDatalog work in real-world applications requires more than probabilistic facts and rules, and the semantics associated with the evaluation of the programs.  ...  Probabilistic Datalog (PDatalog, proposed in 1995) is a probabilistic variant of Datalog and a nice conceptual idea to model Information Retrieval in a logical, rule-based programming paradigm.  ...  Full-text Search A potential application of the Bayes operator is a probabilistic variant of the famous TF-IDF ranking formula widely used in information retrieval.  ...

A probabilistic relational algebra for the integration of information retrieval and database systems

Norbert Fuhr, Thomas Rölleke
1997 ACM Transactions on Information Systems  
With regard to databases, the approach allows for representing imprecise attribute values, whereas for information retrieval, probabilistic document indexing and probabilistic search term weighting can  ...  Based on intensional semantics, the tuple weights of the result of a PRA expression always conform to the underlying probabilistic model.  ...  Rabitti and Savino [1990] describe an advanced system for retrieval of multimedia data (including facts). Their system uses probabilistic retrieval for text as well as for facts.  ...

Probability Based Clustering for Document and User Properties [article]

Thomas Mandl, Christa Womser-Hacker
2011 arXiv   pre-print
The extension presented in this article allows overlapping, probabilistic clusters of features to further refine the process.  ...  Information Retrieval systems can be improved by exploiting context information such as user and document features.  ...  Domain and text type may also be useful. Research will discover more properties in the future. The extended MIMOR model leaves room for the integration of several other features.  ...

1998 Proceedings of the 21st annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '98  
We describe the design and implementation of a system for logic-based multimedia retrieval.  ...  As highlevel logic for retrieval of hypermedia documents, we have developed a probabilistic object-oriented logic (POOL) which supports aggregated objects, different kinds of propositions (terms, classifications  ...  On the other hand, both approaches deal with nested objects, and the retrieval strategy of the FMM is already integrated in POOL.  ...

Hierarchical Machine Learning – A Learning Methodology Inspired by Human Intelligence [chapter]

Ling Zhang, Bo Zhang
2006 Lecture Notes in Computer Science  
Specifically, we propose the Probabilistic Model Supported Rank Aggregation (PMSRA) method to accomplish this integration.  ...  We may consider each modality as a projection of the same object (video) and integrate information from the projections.  ...  In fact, if we look at (X 1 , F 1 , f 1 ) and (X 2 , F 2 , f 2 ) as probabilistic models for two rank lists from different modalities, F 1 and F 2 are the mixed distributions, and f 1 and f 2 are likelihood  ...

An approach to natural language for document retrieval

B. Croft
1987 Proceedings of the 10th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '87  
Document retrieval systems have been restricted, by the nature of tile task, to techniques that can be used with large numbers of documents and broad domains.  ...  The proposed NLP techniques are used to develop a request model based on "conceptual case frames" and to compare this model with the texts of candidate documents.  ...  We would like to thank Wendy Lehnert and Daniel Suthers for their advice on the parser, and on REST, respectively.  ...
