4 Product Classification Problem 1.E-Catalogs contain thousands of cryptic product descriptions 1.CAREPAQ BUREAU PROSIGNIA3YRS/SITE/J+1/TEL 2.TRAINING ACT/ASEEXCEPT TRU64UNIX and OPENVMS 3.…. 2.Businesses have to deal with thousands of e-catalogs 3.Classification standards have tens of thousands of product categories (21192 in UNSPSC 8.04) 4.The result: high manual classification effort is required © STI Innsbruck & Excogito. All Rights Reserved.

5 many standards (e.g. UNSPSC, ebXML, GPC, …), – ~ classes, – millions of products Current SOA: Outsourcing to low-salary countries or use of (counterproductive) low level quality software tools with 25% failure rates GoldenBullet 2 research prototype offered an exclusive "semi-automatic" functionality to support the classification by manual intervention and to achieve by "learning" a classification level of 95% and speed up the process up to 60 times The development of the GB IC product into a marketable product will be an innovative creation of added value and help to reduce outsourcing of labor. GB IC Positioning and Objectives

6 Project intro 1.Project won ProIT funding (cooperation between transIT and CAST) 2.Duration: 1st September st August Objectives: Submission of a debugged, robust and marketable GB IC Prototype Extended Usability and Robustness Extended Reusability 4.Completed tasks & Status: Worked out contract for handling IPR between stakeholders (UIBK, Excogito NL, BvW Global Pty) Including foundation regulations for marketing and selling 1 st report with deliverable of the technical specification accepted by CAST and transIT Cooperation with industrial partner Excogito © STI Innsbruck & Excogito. All Rights Reserved.

7 Workflow Driven Approach 1.GoldenBullet semi-automatically classifies product descriptions into a standard (e.g. UNSPSC) by employing 1.NLP techniques to preprocess descriptions (stemming) 2.Clustering methods to generate representative sub-sets of e- catalog (currently k-means) 3.Machine learning techniques to train the system and automatically generate ranked classification options (currently Naïve Bayes) 2.The user approves or corrects the proposed classification 3.GoldenBullet constantly learns from the user choices and updates the classification options © STI Innsbruck & Excogito.

8 Architecture © STI Innsbruck & Excogito. All Rights Reserved. Mapping the workflow to functional modules: Seperation of concerns Workflow support to be implemented in the GUI

9 © STI Innsbruck & Excogito. All Rights Reserved. Architecture © STI Innsbruck & Excogito. All Rights Reserved. Enhanced Usability and Robustness : - Provide sort and search functions for catalogue AND classification schema - Multi-language GUI and contextual help-system - Support of catalogue sizes of up to 10^6 - Action logging enables undo / redo for classification and user workflow - Implementation of strategies for the avoidance of over-fitting

10 © STI Innsbruck & Excogito. All Rights Reserved. Architecture © STI Innsbruck & Excogito. All Rights Reserved. Enhanced reusability: - Software can be deployed in a Java Enterprise Edition Application Server (e.g. Tomcat, all major vendors) -The Java EE XML Registry is instrumented for storing and accessing classification schema data - Enables customer catalogue taxonomies to be stored and exchanged over a common format. - Documentation (SW Design, User guide, Feature list), JUnit, JavaDoc

11 Conclusions and Future 1.GoldenBullet is a semi-automatic product classification system that offers significant reduction of e-catalog classification effort 2.GoldenBullet IC considerably improves (re-) usability and robustness of the system 3.In future we aim at: 1.Implementation & validation of the technical specification 2.Generation of awareness (transIT) 3.Evaluation of further (possibly new) options of marketable exploitation © STI Innsbruck & Excogito.
