CreaDO -- A Methodology to Create Domain Ontologies Using Parameter-Based Ontology Merging Techniques

Sabino Pariente Ju´rez, Hugo Estrada Esquivel, Alicia Martinez Rebollar, Mari Carmen Su´rez-Figueroa
2011 2011 10th Mexican International Conference on Artificial Intelligence  
CreaDO focuses on performing a parameter-based ontology merge that allows the creation of a domain ontology only with relevant information for the ontology purpose.  ...  Domain ontologies can be used for different purposes; one of them is the development of semantic search engines that obtain precise results by considering the meaning of the Web content.  ...  They also discuss how to extend the merge algorithm by providing auxiliary information, such as additional relationships among source and target concepts, in order to semantically improve the final result  ...

Sentence Clustering Using Parts-of-Speech

Richard Khoury
2012 International Journal of Information Engineering and Electronic Business  
We demonstrate the features of this algorithm by implementing it in a question type classification system, in order to determine the positive or negative impact of different changes to the algorithm.  ...  The algorithm generates and merges together the clusters using a syntactic similarity metric based on a hierarchical organization of the parts-of-speech.  ...  Fig 7 : 7 Performance of the second quality evaluation method for different merger bonus values, with (solid grey line) and without (dotted black line) the final filtering step.  ...

AViTExt: Automatic Video Text Extraction; A new Approach for video content indexing Application

Baseem Bouaziz, Tarek Zlitni, Walid Mahdi
2008 2008 3rd International Conference on Information and Communication Technologies: From Theory to Applications  
The temporal redundancy is then used to filter these regions and forms an effective text region.  ...  A significant difference between homologous blocks implies the appearance of an important object which may be a text region.  ...  For that this filtering process is based on three criteria: the size of region, the contrast variation and the temporal redundancy.  ...

Heterogeneous Map Merging: State of the Art

Andersone
2019 Robotics  
The resulting maps from robots with different specifications are heterogeneous, and eventhough some research on how to merge fundamentally different maps exists, it is limited to specificapplications.  ...  While theexisting robot map and environment model merging techniques allow merging certain homogeneousmaps, the possibility to use sensors of different physical nature and different mapping algorithms  ...  In the map merging regarding particle filters, a decision must be made how to handle the particle merging. Ballesta et al. [55] merges only the most probable particles, Ozkucur et al.  ...

Merge Method for Shape-Based Clustering in Time Series Microarray Analysis [chapter]

Irene Barbero, Camelia Chira, Javier Sedano, Carlos Prieto, José R. Villar, Emilio Corchado
2012 Lecture Notes in Computer Science  
This paper proposes a novel merge method to accomplish this goal obtaining clusters with highly correlated genes.  ...  The main idea of the proposed method is to generate a clustering, starting from clusterings created from different time series individually, that takes into account the number of times each clustering  ...  Conclusions and Future Work A clustering merge method was proposed to combine the information provided by different time series for time-course microarray analysis.  ...

Comparison between Mallat's and the 'à trous' discrete wavelet transform based algorithms for the fusion of multispectral and panchromatic images

M. González‐Audícana, X. Otazu, O. Fors, A. Seco
2005 International Journal of Remote Sensing  
In spite of its a priori lower theoretical mathematical suitability to extract detail in a multiresolution scheme, the 'à trous' algorithm has worked out better than Mallat's algorithm for image merging  ...  All these have been used to merge Ikonos multispectral and panchromatic spatially degraded images.  ...  This implies that for each spectral band we obtain three merged bands coming from the different RGB compositions.  ...

Spatial and Color Spaces Combination for Natural Scene Text Extraction

Celine Mancas-Thillou, Bernard Gosselin
2006 2006 International Conference on Image Processing  
To merge text pixels together, complementary clustering distances are used to support simultaneously clear and well-contrasted images with complex and degraded images.  ...  Moreover, a new method is proposed in this paper to handle uneven lighting, blur and complex backgrounds which are inherent degradations to natural scene images.  ...  [3] use an entropy-based thresholding on each RGB color channel for several video frames and based on the silhouette criterion experienced in Section 6, the three subimages are merged to constitute  ...

A Multistage Motion Vector Processing Method for Motion-Compensated Frame Interpolation

Ai-Mei Huang, T.Q. Nguyen
2008 IEEE Transactions on Image Processing  
The motion vector reliability information is also used as a prior knowledge in motion vector refinement using a constrained vector median filter to avoid choosing identical unreliable one.  ...  We also propose using chrominance information in our method.  ...  Unlike the methods in [11] , which uses prediction difference as the weighting factor for each MV in vector median filter, our method simply does not use those neighboring unreliable MVs.  ...
