This project applies expert system technology to the task of searching online collections of documents . We are developing an intelligent search intermediary to help end-users locate relevant passages in large fulltext databases. Our expert system will automatically reformulate conte.xtual Boolean queries to improve search results and will present re~rieved passages in decreasing order of relev...

With the rapid growth of online text information and user accesses, query-processing efficiency has become the major bottleneck of information retrieval (IR) systems. This paper proposes two new full-text indexing models to improve query-processing efficiency of IR systems. By using directed graph to represent text string, the adjacency matrix of text string is introduced. Two approaches are pr...

We present a distributed full-text index for big data applications in a distributed environment. The index can be used to answer different types of pattern matching queries (existential, counting and enumeration) and also be extended to answer document retrieval queries (counting, retrieve and top-k). We also show that succinct data structures are indeed useful for big data applications, as the...

One of the toughest problems to solve when deploying an enterprise-wide full-text search system is to handle the access rights of the documents and intranet web pages correctly and effectively. Post-processing the results of general-purpose fulltext search engine (filtering out the documents inaccessible to the user who sent the query) can be an expensive operation, especially in large collecti...

P. Case Powerful queries of character strings, numbers, dates, and nodes are familiar to users of relational database systems. Full-text database search systems feature queries that (1) use logical, proximity, and starts-with operators, (2) offer user control of case and diacritics, stemming, and wildcards, and (3) support thesauruses, taxonomies, and ontologies. Two emerging standards, XQuery ...

Summary: Abstracts in biomedical articles can provide a quick overview of the articles but detailed information cannot be obtained without reading full-text contents. Full-text articles certainly generate more information and contents; however, accessing full-text documents is usually time consuming. Condensedly is a web-based application, which provides readers an easy and efficient way to acc...

An ever growing number of XML repositories are being made available for search. A lot of activity has been deployed in the past few years to query such repositories. In particular, full-text querying of text-rich XML documents has generated a wealth of issues that are being addressed by both the database (DB) and information retrieval (IR) communities. The DB community has traditionally focused...
