Increased information retrieval capabilities on e-commerce websites using scraping techniques

When the number of accessible sources of information is so much and even unlimited, the information retrieval process becomes very complicated. Visiting information resources one by one and comparing data or information from all the information sources visited will add much time to the process of rediscovering the information. It takes a technique that can gather information from multiple sources into a single entity to facilitate the process of information retrieval. This study uses 3 e-commerce websites as a source of information. By utilizing the crawling procedure will generate new variables that can store data from the source information, which then these data will be stored in a database. Web crawling works by taking HTML tags as needed, using scrapping techniques. Furthermore, by collecting the data in the database, the information retrieval process can be done easily, and by using the query, this process can be done in less time with 100% recall rate and 93.9 % precision rate.
