Prototype for Integrating Probabilistic Fact and Text Retrieval
نویسندگان
چکیده
We describe a prototype for an information system that integrates text and fact retrieval. A query is a set of conditions which relate either to the text or the attribute values of a database object. Conditions may be assigned weights w.r.t. the query as well as to an object. These weights form the basis for a ranking of the database objects w.r.t. the query. As user interface, the system provides a menu-oriented browser.

Integrating INQUERY with an RDBMS to Support Text Retrieval
Information is a combination of structured data and unstructured data. Traditionally, relational database management systems (RDBMS) have been designed to handle structured data. IR systems can handle text (unstructured data) very well but are not designed to handle structured data. With present day information being a combination of structured and unstructured data, there is an increasing dema...
متن کاملA probabilistic method for keyword retrieval in handwritten document images
Keyword retrieval in handwritten document images (word spotting) is very challenging given that OCR accuracy is not yet adequate for handwritten scripts, specially with large lexicons. Various proposed approaches build indices on information such as image features or OCR scores and have improved the performance of the traditional approach that builds index on OCR’ed text. In this paper, we impr...
متن کاملImage retrieval using the combination of text-based and content-based algorithms
Image retrieval is an important research field which has received great attention in the last decades. In this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. For text-based features, keywords and for content-based features, color and texture features have been used. Query in this system contains some keywords and an input...
متن کاملParallel, Platform-Independent Implementation of Information Retrieval Algorithms
The relational platform provides a flexible, low maintenance environment for integrating searches of structured and unstructured data. We present relational algebra for the Information Retrieval problem and SQL for leading probabilistic retrieval approaches. We tested 150 standard Text Retrieval Evaluation Conference queries against a collection of half a million documents. Because of the paral...
متن کاملSupport concept-based multimedia information retrieval: a knowledge management approach
Identified as an important management concept five years ago (Gamer 1999), knowledge management (KM) aims to enable organizations to capture, organize, and access their intellectual assets. This paper proposes a prototype system that applies a knowledge management approach to support concept-based multimedia information retrieval by integrating various information analysis and image processing ...
