Efficient retrieval of partial documents

Justin Zobel, Alistair Moffat, Ross Wilkinson, Ron Sacks-Davis
1995 Information Processing & Management  
Management and retrieval of large volumes of text can be expensive in both space and time.  ...  Moreover, the range of document sizes in a large collection such as trec presents difficulties for both the retrieval mechanism and the user.  ...  A partial sort using a tree structure should then be used to extract the top documents.  ...

Efficient Structure Oriented Storage of XML Documents Using ORDBMS [chapter]

Alexander Kuckelberg, Ralph Krieger
2003 Lecture Notes in Computer Science  
Measurement results are shown and shortly discussed for creation and retrieval of different (complete) XML documents.  ...  To make these tree graphs persistent different storage techniques are mentioned and evaluated concerning the creation and retrieval of complete documents.  ...  Retrieving small parts of a document is efficient, too, but the retrieval of large parts or of the whole document leads to bad retrieval performances.  ...

A Survey of Information Retrieval Models for Malayalam Language Processing

Arjun Babu, Sindhu L.
2014 International Journal of Computer Applications  
There are several Information Retrieval models developed for efficient document retrieval. In this survey paper we describe major IR models which are used for various document retrieval purposes.  ...  Information retrieval is concerned with the storage of text documents and their subsequent retrieval in response to user's requests for information.  ...  There is no partial match to the query condition. Partial match allows retrieval of documents that approximate the query conditions.  ...

Application of bitmap index to information retrieval

Kengo Fujioka, Yukio Uematsu, Makoto Onizuka
2008 Proceeding of the 17th international conference on World Wide Web - WWW '08  
We developed the HS-bitmap index for efficient information retrieval.  ...  The hierarchical summary bits provide bitmap indices with efficient bit operations, usage of space for large sparse bitmaps, and partial decompression.  ...  We also measured retrieval times for bag-of-words queries while varying query terms. When document frequencies (Df) of terms are large, e.g., stop words, the HS-bitmap index is not efficient.  ...

The efficiency of inverted index and cluster searches

Ellen M. Voorhees
1986 Proceedings of the 9th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '86  
The efficiency of each search is measured in two ways: the number of bytes required to store the auxiliary files required by the search, and the mean time required to retrieve a set of documents for a  ...  Jntroduction Research by Griffiths et al. suggests that the single link clustering method is not as effective as other agglomerative, hierarchic clustering methods for document retrieval [GRIFM.  ...  Acknowledgments Thanks go to Professor Gerard Salton and the members of the SMART group at Cornell for many helpful discussions, and especially for suggestions on how to improve the efficiency of the cluster  ...

Applying I-FGM to image retrieval and an I-FGM system performance analyses

Eugene Santos, Jr., Eunice E. Santos, Hien Nguyen, Long Pan, John Korah, Qunhua Zhao, Huadong Xia, Kevin L. Priddy, Emre Ertin
2007 Intelligent Computing: Theory and Applications V  
Based on the obtained partial results, we refine our computational resources by updating the priority values of image documents. Experiments have been conducted on I-FGM system with image retrieval.  ...  Similar to what we did for text retrieval, we modified the WALRUS algorithm to partially and incrementally extract the regions from an image and measure the similarity value of this image.  ...  Therefore, this paper focuses on image retrieval in our I-FGM. The immediate objective is the verification of the effectiveness and efficiency of I-FGM for retrieving information from images.  ...

Eugene Santos, Eunice E. Santos, Hien Nguyen, Long Pan, John Korah
2010 Applied intelligence (Boston)  
It serves as an umbrella framework in which the various tools and techniques available in information retrieval can be used effectively and efficiently.  ...  One of the main problems facing human analysts dealing with large amounts of dynamic data is that important information may not be assessed in time to aid the decision making process.  ...  For query 1, out of 9 documents, I-FGM retrieves 5 documents faster than other systems. It ties with Partial-Intelligent for 2 other documents.  ...
