چکیده
The SMART system is designed to provide a flexible test bed for evaluating a variety of potentially useful methods of automatic content .analysis in information retrieval. SMART is primarily a document retrieval system; however, many of the analysis techniques employed are also applicable to other phases of information retrieval, including fact retrieval and question-answering systems. This section introduces a generalized model of the system and derives several evaluation indices which will be used to determine the influence of the various system parameters.

Improved Skips for Faster Postings List Intersection
Information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. The document processor, matching function and query analyzer are the main components of an information retrieval system. Document retrieval system is fundamentally based on: Boolean, vector-space, probabilistic, and language models. In this paper, a new methodology for mat...

متن کاملDocument Image Retrieval Based on Keyword Spotting Using Relevance Feedback
Keyword Spotting is a well-known method in document image retrieval. In this method, Search in document images is based on query word image. In this Paper, an approach for document image retrieval based on keyword spotting has been proposed. In proposed method, a framework using relevance feedback is presented. Relevance feedback, an interactive and efficient method is used in this paper to imp...
متن کاملUnaligned Binary Codes for Index Compression in Schema-Independent Text Retrieval Systems
We examine index compression techniques for schemaindependent inverted files used in text retrieval systems. Schema-independent inverted files contain full positional information for all index terms and allow the structural unit of retrieval to be specified dynamically at query time, rather than statically during index construction. Schemaindependent indices have different characteristics than ...
متن کاملAngiographic patterns of in-stent restenosis: classification and implications for long-term outcome.
BACKGROUND The angiographic presentation of in-stent restenosis (ISR) may convey prognostic information on subsequent target vessel revascularizations (TLR). METHODS AND RESULTS We developed an angiographic classification of ISR according to the geographic distribution of intimal hyperplasia in reference to the implanted stent. Pattern I includes focal (< or =10 mm in length) lesions, pattern...
