Session Objectives


Information Management Challenges

  • Quantity of information within and outside of enterprises has grown exponentially

  • Challenge to extract relevant information from a multitude of sources

  • Integrating extracted content that may be in different formats (EAI issues)


Information Management Challenges

  • Task Specific Customization or Personalization

  • Combine data from several different sources into a new data source

  • Data aggregation for mining and analysis

  • Bottled up data by artificial network or security barriers


Existing Capture Methodologies By Other Vendors

Static data stored in databases

  • Not equivalent to storing dynamic data

  • Need to refreshed at regular intervals

  • Legal problems

  • More infrastructure investment


Existing Capture Methodologies By Other Vendors

Screen Scraping

  • Snooping the contents of some display memory of a smart terminal through its auxillary port

  • Parsing the HTML with programs designed to mine out patterns of content

  • Ugly, ad-hoc very likely to break on even minor changes to the format of the data being snooped.


Content Capture Technology Suite (CCTS)

What does it do ?

  • Set of API that capture dynamic content from a variety of sources into individual elements

  • Deploy and replay captured elements in any portal framework

  • Aggregate data from multiple sources into XML


Technology Map


Technology Driving CCTS – Feature Extraction

Traditional Extraction Methodology

  • Outside in, based on HTML tags

  • Content feed breaks if page changes slightly


Technology Driving CCTS – Feature Extraction

CCTS Extraction Methodology

  • Inside out, based on features of content desired


Object Identification


Technology Driving CCTS – Feature Extraction

Feature Extraction (FE) ensures reliability of content aggregation

  • Parses out information on a page and breaks down into specific components

  • Fuzzy logic “digital signature” or symbolic reference rather than a static link ensures persistent extraction of desired content

  • Pattern recognition through “object specific” parsers enable an extendable set of aggregated object


Technology Driving CCTS – CCL

Content Collection Language (CCL)

  • ‘Content bundle’ of everything needed to collect and playback desired content

  • Designed to be programmed through a user interface instead of by hand

  • Simple as a URL, but as powerful as a web scripting language


Technology Driving CCTS – Navigation

  • Tightly coupled with Content Collection Language

  • Written in Java

  • Servlet based and can be easily tied to a GUI


Technology Driving CCTS – CCL (continued)

  • New commands are easily added, not keyword based language

  • Can reside on the client or the server

  • Parsing and error management are shared by all commands.

  • Fast execution.

  • Used to eliminate session/calls to DB


CCTS Architecture GUI or API


CCTS Components

Content Capture Engine

  • Takes in user input via a navigation GUI and generates the CCL or XML

    Playback Engine

  • Translates CCL statements into content

    Content Repository Interface

  • Deploy captured content into any portal repository


CCTS Components

Content Capture Workbench

  • Eclipse based GUI that allows users to capture and deploy content using a GUI

  • Reference implementation of Capture and CRI API

  • Design pattern that can be used as a reference to integrate any custom GUI to the CCTS API


Suite of Powerful Content Aggregation Tools

DataParts reduces the number of data tasks that require a programmer, and makes the remaining tasks easy to accomplish.


Range of Solution Options


EAI Tools

  • Grid Charts

  • Messaging Portlets

  • Integrated Scripting Environment

Demo : Sailing Event Web Application

Scenario

  • You are a portal developer for a company managing sailing events

  • Assigned a task of creating a portal containing following information

    • Race Sites

    • Live weather information

    • Wind speed for last 12 hours as a graph

    • Tide information as a graph

    • Marine weather
