PROBLEM & MOTIVATION

GeBIZ is a Singapore Government’s one-stop e-procurement portal which facilitates the entire procurement lifecycle and revenue tender activities between Singapore government and local and overseas supplies electronically since June 2000. The purpose of the portal is to be transparency, encourage fair and open competition and to generate demands / quotations. With this portal, more companies are tendering for projects hence increasing the competitiveness.

We aim to create a visualisation which benefits businesses in crafting bidding prices and increasing their chances in winning the government contracts and tender. In addition, we hope to give an overview and identify interesting patterns of government spending.

OBJECTIVES

In this project, we are creating a visualisation that is able to show the following:

• Government investment analysis
• The tender distribution of projects to different type of business
• Identify the price range when bidding for projects

SELECTED DATASETS

The following datasets will be used for analysis , as elaborated below:

Dataset/Source	Data Attributes	Rationale of Usage
Government Procurement Data (https://data.gov.sg/dataset/government-procurement)	Tender No Agency Tender Description Award Date Tender Detail Status Supplier Name Awarded Amount	To gain information on government procurement such as tender description, amount and supplier information
Ministry and Agencies List	Ministry Agency	We will be looking through the Singapore Government Directory (https://www.gov.sg/sgdi/ministries) to categorise the agencies into their respective ministries. This will allow us to visualise the procurement spending on a ministry level.

Text Classification using Support Vector Classifier (SVC)

One of the key challenges of working with the provided procurement dataset is the absence of categorization of each procurement transaction. Instead of labelling manually, we applied machine learning to classify the tender descriptions into different categories. We firstly scraped the procurement descriptions and categories from GeBiz website using Selenium and BeautifulSoup libraries in Python to be used as the training and validation dataset in our Support Vector Classifier model. We were able to achieve 90% for training accuracy before performing the categorization prediction.
