The search operation in PDF document has become very indispensable now a days and loads of research have being organized to store and process the index required for search operation in a very simple and effective manner. Whenever indexes are stored, its access time is large and it requires large amount of storage space. The above techniques have some limitation like it can be done only for smal...

Most index pruning techniques eliminate terms from an index on the basis of the contribution of those terms to the content of the documents. We present a novel syntactically-based index pruning technique, which uses exclusively shallow syntactic evidence to decide upon which terms to prune. This type of evidence is document-independent, and is based on the assumption that, in a general collecti...

New applications of database management systems as in office automation and engineering require the system to process both textual and formatted data. To support text search appropriately, text indexes must be created and on-line text index maintenance be provided. Unfortunately, text index maintenance. is generally a time-consuming task and does not fit well in an on-line environment, where sh...

Pattern-based video coding focusing on moving regions has already established its superiority over the H.264 at very low bit rate. Up to a certain limit, the larger the number of pattern templates, the better the approximation to the moving regions. However, beyond that limit no coding gain is observed due to the need of an excessive number of pattern identification bits (PIC). Recently, distri...

Under the Vector Space Model Tak W. Yan and Hector Garcia-Molina Department of Computer Science Stanford University Stanford, CA 94305 Abstract With the ever increasing volumes of electronic information generation, users of information systems are facing an information overload. It is desirable to support information ltering as a complement to traditional retrieval mechanism. The number of user...

Mapping medical knowledge into a relational database became possible with the availability of personal computers and user-friendly database software in the early 1990s. To create a database of medical knowledge, the domain expert works like a mapmaker to first outline the domain and then add the details, starting with the most prominent features. The resulting "intelligent database" can support...

We have proposed an information filtering system using index word selection from a document set based on the topics included in a set of documents. This method narrows down the particularly characteristic words in a document set and the topics are obtained by Sparse Non-negative Matrix Factorization. In information filtering, a document is often represented with the vector in which the elements...

Both Geographic Information Systems and Information Retrieval have been very active research fields in the last decades. Lately, a new research field called Geographic Information Retrieval has appeared from the intersection of these two fields. The main goal of this field is to define index structures and techniques to efficiently store and retrieve documents using both the text and the geogra...
