The structured query language (SQL) of relational database models does not have the expressive power to implement recursive queries. Consequently, recursive queries are implemented as an application program in the host language. The newly developed XML schema provides a different setting for database design and query implementation. In this paper, we design and implement an XML schema and a set of...
In this paper, we give a detailed description of a bibliographic database, a set of recursive queries, an overview of some standard query processing algorithms, and an implementation of these queries in DATALOG.
In this paper, we report on the identification of document type using a k-dependence Bayesian categorization engine. In particular, we show that the use of font and capitalization as features improves precision and recall.
We describe the development of a tool to identify the names of persons and their corresponding institutions as they appear in the "carbon copy" or "cc" lists of correspondence, memorandums, emails, and other types of documents.
In this paper, still images are modeled by hierarchical tree structures and object relational graphs. These modeling concepts can be described naturally using XML schema. We introduce the notion of complex types and referential integrity to fully describe the physical and semantic properties of images. We further show how complex types of XML can be used to overcome the shortcomings of reported in...
. Techniques are presented to directly process JBIG-encoded document images. Two experimental processing pipelines are designed to evaluate the performance of the methods from the application perspective. They are document segmentation for obtaining the global layout and the form processing system for form type identification and the form dropout. The JBIG coding context is employed to perform horizontal...
