A new approach to text searching

R. A. Baeza-Yates, G. H. Gonnet
1989 Proceedings of the 12th annual international ACM SIGIR conference on Research and development in information retrieval - SIGIR '89  
We introduce a family of simple and fast algorithms for solving the classical string matching problem, string matching with don't care symbols and complement symbols, and multiple patterns.  ...  In addition we solve the same problems allowing up to k mismatches.  ...  We have to report a match if s, is 0, or equivalently if state < . ..lllOmsl.To update the state after reading a new character on the text, we have to: l shift the vector state b bits to the left to reflect  ...

Using ephemeral clustering and query logs to organize web image search results on mobile devices

Jose G. Moreno, Gaël Dias
2011 Proceedings of the 2011 international ACM workshop on Interactive multimedia on mobile and portable devices - IMMPD '11  
For that purpose, we suggest to expand the original query based on labels of Ephemeral Clusters and compare it to a Query Log based approach.  ...  The recent shift in human-computer interaction from desktop to mobile computing fosters the needs of new interfaces for web image search results exploration.  ...  A set of new related queries are then defined based on the original query combined with the cluster names. New expanded queries are used to search for new results.  ...

Reranking Methods for Visual Search

Winston H. Hsu, Lyndon S. Kennedy, Shih-Fu Chang
2007 IEEE Multimedia  
Most semantic video search methods use text-keyword queries or example video clips and images. But such methods have limitations.  ...  Here the authors introduce two reranking processes for image and video search that automatically reorder results from initial text-only searches based on visual features and content similarity.  ...  A node might correspond to a Web page in the text-retrieval problem or a story in the broadcast news video. We use a stochastic (transition) matrix to govern a random walk process's transition.  ...

Lucene is an excellent full text search engine, its structure has a strong object-oriented features. Lucene source  ...  This paper introduces us the full-text search engine based on Lucene and full-text retrieval technology, including indexing and system architecture, compares the full-text search of Lucene with the String  ...  However, string-Search approach used java long String to search information. You can also use the delete approach to delete operation on the preprocess text document.  ...

MapReduce for Information Retrieval Evaluation: "Let's Quickly Test This on 12 TB of Data" [chapter]

Djoerd Hiemstra, Claudia Hauff
2010 Lecture Notes in Computer Science  
We propose to use MapReduce to quickly test new retrieval approaches on a cluster of machines by sequentially scanning all documents.  ...  We present a small case study in which we use a cluster of 15 low cost machines to search a web crawl of 0.5 billion pages showing that sequential scanning is a viable approach to running large-scale information  ...  We are grateful to Yahoo Research, Barcelona, for sponsoring our cluster.  ...

Video search reranking through random walk over document-level context graph

Winston H. Hsu, Lyndon S. Kennedy, Shih-Fu Chang
2007 Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07  
The random walk is biased with the preference towards stories with higher initial text search scores -a principled way to consider both initial text search results and their implicit contextual relationships  ...  When evaluated on TRECVID 2005 video benchmark, the proposed approach can improve retrieval on the average up to 32% relative to the baseline text search method in terms of story-level Mean Average Precision  ...  A node might correspond to a Web page in the text retrieval problem or a story in the broadcast news video.  ...

Integrating SQL Databases with Content-Specific Search Engines

Stefan Deßloch, Nelson Mendonça Mattos
1997 Very Large Data Bases Conference  
Using this approach the content-specific indexing mechanisms of search engines can be exploited without having to extend the database engine with new access methods, or having to break up the search engine  ...  It is based on a query rewrite scheme that exploits so-called table functions, which are used to pass results from external search engines into the database engine.  ...  Text Search in SQL Databases -a Sample Scenario In order to prepare the grounds for the discussion of our approach, we describe a sample scenario in the area of text search in SQL databases. 2.1 SQL3 and  ...

Thierry Urruty, Frank Hopfgartner, Robert Villa, Nicholas Gildea, Joemon M. Jose
2008 Proceedings of the 8th ACM/IEEE-CS joint conference on Digital libraries - JCDL '08  
In this poster, we present a new approach of using an iterative clustering algorithm on text and visual features to simulate users creating new facets in a facet-based interface.  ...  Video search engines are becoming more and more interactive, helping the user to easily find what he or she is looking for.  ...  Instead of carrying out a search one query at a time, the users may execute, and view, multiple queries, enabling them to structure their retrieval process and to easily follow new retrieval directions  ...
