Definition & Meaning of the Project
The senior design project by Elwin Chai and Rick Jones, named PriceHunter, is an innovative approach to developing an automated price comparison shopping search engine. Unlike traditional search engines that rely on static databases, PriceHunter employs a dynamic method that uses web crawling to find product information directly from online commercial sites. The project aims to provide a more accurate and up-to-date price comparison mechanism.
Key Elements of PriceHunter
PriceHunter's architecture includes several pivotal components:
- Web Crawler: Automates data retrieval from online retail sites without human intervention, ensuring real-time information.
- Heuristics Manager: Evaluates site relevancy and improves search efficiency by applying tailor-made heuristics.
- Database Management System: Utilizes MySQL for effective data storage and management. This structure handles large volumes of data while maintaining performance.
Legal Use and Compliance
When dealing with automated tools such as PriceHunter, it is essential to ensure compliance with legal guidelines. PriceHunter’s operation focuses on ethical web crawling practices, adhering to legal requirements for accessing third-party websites. This includes respecting website terms of service and privacy policies.
Steps to Complete the Development
- Identify Target Websites: Select commercial sites from which to gather pricing data.
- Configure Web Crawler: Customize the web crawler settings to efficiently navigate and scrape data from targeted sites.
- Integrate Heuristics Manager: Develop heuristics rules for assessing site relevance and enhancing data accuracy.
- Set Up Database System: Implement MySQL to store scraped data systematically for retrieval and analysis.
- Test and Validate: Conduct thorough testing to ensure the system functions as intended and improves existing processes.
Who Typically Uses PriceHunter
PriceHunter serves both individual consumers and businesses looking for cost-effective purchasing decisions. Retailers, market analysts, and pricing strategists find significant value in accessing real-time competitor pricing information to adjust their pricing models.
Examples of Using PriceHunter
- A consumer seeking the best deal on electronics can utilize PriceHunter to compare prices across various vendors quickly.
- Retailers might use the engine to benchmark competitor prices, ensuring competitive pricing strategies are in place.
Software Compatibility
PriceHunter's backend system primarily relies on MySQL for database management, which is compatible with various data analysis tools. Its design allows integration with other software systems like TurboTax for enhanced data insights, assuming the retrieval of financial metrics.
Challenges and Future Work
The project highlights several challenges faced during its implementation, such as data inconsistencies and the need for more sophisticated heuristics to refine data extraction. Future work will focus on scalability and enhancing information extraction techniques to handle larger datasets efficiently.
