Retrieval activities in a database consisting of heterogeneous collections of structured text

Forbes J. Burkowski
1992 Proceedings of the 15th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '92  
The database is considered to be a hierarchical collection of contiguous extents each extent being a word, word phrase, text element or non-text element.  ...  The first part of this paper briefly describes a mathematical framework (called the containment model) that provides the operations and data structures for a text dominated database with a hierarchical  ...  Similar information is used by a Full-Text Search Window, in particular, it must be informed of all tags used in the semantic layer.  ...

Automated Annotation of Landmark Images Using Community Contributed Datasets and Web Resources [chapter]

Gareth J. F. Jones, Daragh Byrne, Mark Hughes, Noel E. O'Connor, Andrew Salway
2011 Lecture Notes in Computer Science  
In the first stage, an input image is matched to a set of community contributed images (with keyword tags) on the basis of its GPS information and image classification techniques.  ...  The system then takes advantage of the information written about landmarks available on the web at large to extract a fact about the landmark in the image.  ...  Acknowledgement The research reported in this paper is part of the project TRIPOD supported by the European commission under contract No. 045335.  ...

TAG BASED IMAGE RETRIEVAL (TBIR) USING AUTOMATIC IMAGE ANNOTATION

Karthikram .
2014 International Journal of Research in Engineering and Technology  
This leads to poor performance in Tag Based Image Retrieval (TBIR). Automatic Image Annotation (AIA) analyzes the missing and noisy tags and over-refines it to increase the performance of TBIR.  ...  In recent days, several social networking sites are more popular with digitized images. It comprises the major portion of the databases which makes the search engines to face difficulty in searching.  ...  This technique uses the local and global features for estimating the presence of the training dataset in the given image.  ...

An Image Retrieving Scheme Using Salient Features and Annotation Watermarking

2014 KSII Transactions on Internet and Information Systems  
In this paper, we propose an annotation watermarking system for users to embed text descriptions, and retrieve more relevant textual information from similar images.  ...  Specifically, we use global features such as color ratios and dominant sub-image colors for preliminary filtering.  ...  With the filtering of color ratios and dominant sub-image colors, the system can retrieve a high percentage (more than 96%) of the relevant images and their annotations for relevant information retrieval  ...

Multimodal ranking for image search on community databases

Fabian Richter, Stefan Romberg, Eva Hörster, Rainer Lienhart
2010 Proceedings of the international conference on Multimedia information retrieval - MIR '10  
The image ranking approach presented in this work represents an image collection as a graph that is built using a multimodal similarity measure based on visual features and user tags.  ...  We perform a random walk on this graph to find the most common images.  ...  Typically one would pre-filter the images in the database to keep only those likely showing the query content.  ...

2007 Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07  
The results of 24 queries in a data set of 12,790 videos retrieved from Google, Yahoo!  ...  This paper outlines ways to cluster and filter out the nearduplicate video using a hierarchical approach. Initial triage is performed using fast signatures derived from color histograms.  ...  The tool of near-duplicate detection can be used in several ways: As a filter to remove redundant videos in the listing of retrieval results, as a tool for finding similar videos in different variations  ...

2020 PLoS ONE  
Such filtering of the original database allows slower but more accurate methods to be executed quickly over a far smaller dataset.  ...  Further, the new methods are an order of magnitude faster than BLAST for the database retrieval task, supporting hybrid approaches that rapidly filter the collection so that only potentially relevant records  ...  To apply these approaches to the retrieval task, we consider the protein family tag (retrieved from the PFAM database [18] ) as the class-label for a given sequence.  ...
