Opis:: This paper deals with problems that are related to a feature extraction from 3D objects. The main aim of the feature extraction is to describe a shape of 3D object by a feature vector. Then the elements of this feature vector characterize the shape of the own 3D objects and they can serve as a key in searching for similar models. In this paper are introduced current methods for the feature extraction of 3D models and their classification. These methods are based on different mathematical background and according to that they are separated into several groups.

Opis:: In this paper, we introduce an optimized method to improve the accuracy of content based image retrieval systems (CBIR). CBIR systems classify the images according to low and higher features.In our research, we improve both feature selection and classifier partition of a CBIR system. Results show great performance of our proposed algorithm.

Tytuł:: Some problems of chemical reactions retrieval systems
Autorzy:: Hippe, Z. S.
Powiązania:: https://bibliotekanauki.pl/articles/1954024.pdf
Data publikacji:: 1998
Wydawca:: Politechnika Gdańska
Tematy:: chemical reactions retrieval systems
computer network
computational chemistry
biocomputing
human genes
Opis:: The paper briefly discusses some organisational questions of distribution of chemical information over the computer network, emphasizing various tools available for chemical sciences, mainly: chemical reaction retrieval systems, systems for computer-assisted molecular modelling, then for computational chemistry, biocomputing, and information about human genes. From the above mentioned problems, the chemical reaction retrieval systems, like ORAC, REACCS, and SYNLIB are covered in detail. Additionally, the latest philosophy of searching reaction databases, represented by a family of tools from InfoChem GmbH (ChemReact41, CD-ROM-with over 2.5 min of reactions-and STS), are critically reviewed.

Tytuł:: An optimized soft computing-based passage retrieval system
Autorzy:: Ortiz-Arroyo, D.
Christensen, H. U.
Powiązania:: https://bibliotekanauki.pl/articles/970939.pdf
Data publikacji:: 2009

Tematy:: information retrieval

genetic algorithms
Opis:: In this paper we propose and evaluate a soft computing-based passage retrieval system for Question Answering Systems (QAS). Fuzzy PR, our base-line passage retrieval system, employs a similarity measure that attempts to model accurately the question reformulation intuition. The similarity measure includes fuzzy logic-based models that evaluate efficiently the proximity of question terms and detect term variations occurring within a passage. Our experimental results using FuzzyPR on the TREC and CLEF corpora show that our novel passage retrieval system achieves better performance compared to other similar systems. Finally, we describe the performance results of OptFuzzyPR, an optimized version of FuzzyPR, created by optimizing the values of FuzzyPR system parameters using genetic algorithms.
