A top-down page segmentation technique known as the recursive X-Y cut decomposes a document image recursively into a set of rectanguzar blocks. This paper proposes that the recursive X-Y cut be implemented using bounding bozes of connected components of black pixels instead of using image pizels. The advantage is that great improvement can be achieved in computation. In fact, once bounding boxe...

Phrase matching is a common IR technique to search text and identify relevant documents in a document collection. Phrase matching in XML presents new challenges as text may be interleaved with arbitrary markup, thwarting search techniques that require strict contiguity or close proximity of keywords. We present a technique for phrase matching in XML that permits dynamic specification of both th...

This paper presents the design and implementation of the WebGD, a CORBA-based document classification and retrieval system on Internet. The WebGD makes use of such techniques as Web, CORBA, Java, NLP, fuzzy technique, knowledge-based processing and database technology. Unified classification and retrieval model, classifying and retrieving with one reasoning engine and flexible working mode conf...

Keywords play a vital role in extracting the correct information as per user requirements. Keywords are like index terms that contain the most important information about the content of the document. Keyword Extraction is the task of identifying a keyword or keyphrase from a document that can help users easily to understand the documents. Meeting transcripts is significantly different from docu...

Information Retrieval Systems (IRS) are so popular through World Wide Web. Availability of Text Information related to all types of objects like Documents, Web Pages, Images, Videos and Audio files on web are increasing day by day in an exponential manner. When the text repository grows to the maximum extent of the memory size in the server, the methods used to find a particular text unit eithe...

Now in these days the information need is increasing rapidly in our day to day life therefore a large number of users are accessing data from search engine. The search engines are composed with three major components user query interface, search algorithm and the ranking process. During search process the system evaluate the user input query and the database documents according to best fit docu...

Manual data collection and entry is one of the bottlenecks in conventional disaster management information systems. Time is a critical factor in emergency situations and timely data collection and processing may help in saving several lives. An effective disaster management system needs to collect data from World Wide Web automatically. A prerequisite for data collection process is document cla...

Documents can be assigned keywords by frequency analysis of the terms found in the document text, which arguably is the primary source of knowledge about the document itself. By including a hierarchically organised domain speciic thesaurus as a second knowledge source the quality of such keywords was improved considerably, as measured by match to previously manually assigned keywords.

Automatic keywords extraction is the task to identify a small set of words, key phrases, keywords, or key segments from a document that can describe the meaning of the document.
