A hypermedia system comprises a client computer, server computers for holding contents files, and a directory server computer for intensively managing information about the contents files. These computers are connected via a network. The directory server computer includes a directory information storage means for storing node identifiers, information about the contents of the contents files which are nodes, and information about the linkage relationship between the nodes with respect to the node...

A computer-based document management system that utilizes a geographic interface and allows any interested party to view individually selected location-specific documents which are stored in a particular geographic location from anywhere in the world is disclosed. Examples of the site-specific documents include, for example, MSDS information. Access to this electronically stored information may be had via any suitable medium such as, for example, the internet, the world wide web, an intranet, or...

A computer implemented method and a computer program product that is stored on computer readable media provides a parsing engine which will apply meta-language instructions to parse items discovered in a computer-based search with particular application to web sites accessible using the internet.

The present invention teaches in general how to efficiently exploit active database technology and extensible database technology, i.e. triggers and user-defined functions for processing subscriptions. According to a first aspect of the present invention it is proposed to aggregate all subscriptions on a certain table, or more generally of a plurality of tables, into a single trigger on this table or tables, respectively. This will dramatically improve the trigger-based efficiency. According to ...

When a retrieval condition including a first desired word and a first desired component including a value in which the first desired word is included, is inputted, a first detecting device detects second desired components each being similar to the first desired component, an acquiring device acquirers second desired words each being similar to the first desired word, a first retrieving device retrieves first structured documents each including a first component including a value in which one of...

A database system carries out a technique for use in delivering data of a user-defined type to a requesting system. The system first receives a request from the requesting system for data of the user-defined type. The system then identifies a storage location for the requested data, as well as a storage location for program code designed to allow manipulation of the requested data on the requesting system. The system then retrieves both the requested data and the program code from their respecti...

Methods and systems for prioritizing content are described. A request for a first content object is received at a caching proxy. A search of an access log of the proxy cache for a portion of the first content object is then performed. The size of the portion of the first content object on the proxy cache is calculated and the normally utilized size of the segment of the first content object is derived. A comparison is then made between the size of the portion of the first content object on the p...

An information display apparatus obtains a plurality of pieces of web data from one or more web servers connected to a network, each piece of web data composing either a portion of or a whole web page. The information display apparatus then receives an instruction from a user for specifying information to be extracted from each of the obtained pieces of web data, extracts the specified information from each of the obtained pieces of web data, constructs one screen using the extracted information...

In order to provide pages relating to a prescribed page to a user in a precise manner over the internet, a site page processor collects pages included at various sites, determines parent-child relationships between the pages, and stores the results of such determinations in a site page data storage section. A related page data processor calculates the relevance between pages using page feature extraction values given weightings taking into consideration at least one of a sibling relationship and...

To efficiently process a parameterized query against a relational database in a streaming transaction processing system, the transaction stream is treated as a sequence of multi-record "chunks" and a single "quasi-batch" query is executed for each chunk. A specific table in the database holds the parameter values obtained from each transaction and the parameters are bound to the rest of the query by using a database join. Another embodiment uses a framework that automates the technique by accept...
