Abstract

Claims (35)

1. A distributed system for large volume deep web data extraction comprising:

a distributed scrape campaign controller module stored in a memory of and operating on a processor of a computing device;

a scrape request data store stored in a memory of and operating on a processor of a computing device;

a scrape request monitor module stored in a memory of and operating on a processor of a computing device;

one or more scrape servers stored in a memory of and operating on a processor of one of more computing devices;

a persistence service module stored in a memory of and operating on a processor of a computing device;

a persistence data store stored in a memory of and operating on a processor of a computing device; and

an output module stored in a memory of and operating on a processor of a computing device;

wherein the distributed scrape campaign controller module:

(a) receives scrape control and spider configuration parameters from a plurality of software applications through an HTTP based API;

(b) receives scrape control and spider configuration parameters from either a computer terminal or a plurality of software applications through a command line interface;

(c) uses the scrape request data store to store both generalized search control parameters and configuration parameters specific to individual web search agents (spiders) derived from the HTTP based API and command line interface directives;

(d) coordinates one or more World Wide Web searches (scrapes) using both general search control parameters and spider specific configuration data;

(e) receives scrape progress feedback information from the request data store monitor module, and based on at least a portion of the received scrape progress feedback information issues further web search control parameters; and

wherein the scrape request data store:

(f) receives World Wide Web search control parameters and spider specific configuration information from the distributed scrape campaign controller;

(g) stores scrape control parameters, spider configuration parameters, scrape status data; and

wherein the scrape request monitor module:

(h) monitors the scrape status data stored for each ongoing search in the scrape request data store;

(i) processes the scrape status data as programmatically pre-determined for the search monitored;

(j) sends at least a portion of the processed scrape status data to the distributed scrape campaign controller module; and

wherein at least one of the one or more scrape servers:

(k) hosts a plurality of individual web search agents (spiders);

(l) receives scrape specific control directives and spider configuration parameters from the distributed scrape campaign controller module;

(m) controls and monitors a plurality of independent spiders on the server;

(n) returns scrape status data from at least one of the plurality of independent spiders deployed from the server to the distributed scrape campaign controller and scrape request data store;

(o) sends web page data retrieved by the independent spiders to the persistence service module for storage or output; and

wherein the persistence server module:

(p) receives scrape campaign data from at least one of the one or more scrape servers;

(q) aggregates the scrape campaign data;

(r) performs pre-requested scrape campaign data transformations prior to providing the scrape campaign data for storage or output; and

wherein the output module:

(s) produces results in a format pre-determined by the owners of a scrape campaign.

2. The system of claim 1 wherein a plurality of archetype spiders are provided by a program library and individual spiders are created using configuration files.

3. The system of claim 1 where scrape campaign requests are persistently stored and can be reused or used as the basis for additional scrape campaigns.
