The present invention relates to a network analyzing system that performs analyzing for a network. The network analyzing system includes one or a plurality of data processing modules and a network analysis apparatus, the network analysis apparatus includes a unit for accommodating the data processing modules, a unit for holding data-to-be-analyzed, a unit for storing data processing definition information that defines steps that carry out the processing of the data-to-be-analyzed using the data processing modules, a unit for causing the data processing modules to carry out data processing based on the data processing definition information to obtain a data processing result, and each data processing module includes a unit connecting to the network analysis apparatus, and a unit for carrying out data processing in accordance with a request.

Network analyzing system, as well as network analyzing apparatus and network analyzing program, as well as data processing module and data processing program

In an approximation computation apparatus, a location monitor designates, each time the number of data of a received data sequence exceeds an integer l, a starting location of the received data for calculating reduced received-data; a dimensionality reducer dimensionally reduces each data sequence including the received data after the corresponding designated starting location by random projection to generate the reduced received-data; an object selecting controller controls an object in response to a result of monitoring from the location monitor of the number of the received data reaching another integer n, deletes currently-stored object data, selects the reduced received-data after the oldest reduced received-data in the reduced received-data, and substitutes and updates an object data sequence to the selected reduced received-data; and a coefficient approximator calculates an approximate value of a wavelet coefficient on the basis of the object data and a wavelet matrix.

Processing apparatus for calculating an approximate value to an analytical value with a tolerance maintained and a method therefor

A bandwidth control system controls the bandwidths used by plural web crawlers. The bandwidth control system receives a connection request from one of the web crawlers for establishing a connection between that web crawler and a content server. The control system records each of the web crawlers in association with a content server to which that web crawler is connected. The control system monitors the traffic on the content servers to which the web crawlers are connected. When the traffic on the content server recorded becomes too heavy, the control system disconnects the web crawler from the content server to which the crawler is connected.

Bandwidth control system and method capable of reducing traffic congestion on content servers

This invention provides an electronic document update notification device for notifying a user of update information of an electronic document including: a updated document name generating partfor generating a updated document name based on a stylized document name; a document data obtaining partfor obtaining document data after update based on the updated document name; a difference extracting partfor extracting difference data between document data before update and the document data after update; and an update information creating partfor creating an update information notification based on the difference data. This makes it possible to notify a user of the update information of the electronic document even when a document after update is created with the document name with the document name before update changed according to a predetermined rule, at the time of update of the electronic document.
