Abstract
With the massive amounts of data on the web, finding information and items on the net is becoming an increasingly critical issue. When the user is generally exploring the collection, browsing is usually more suitable for the task. However, traditional browsing can sometimes be inefficient and confusing. Thus, multifaceted browsing interface was invented.
Multifaceted browsing systems are flexible and convenient therefore has a high credit from users. Yet its shortcomings prevent itself from becoming commonly adopted in practice. Among them, the most concerning issue is the long response time of the system. Due to its high complexity queries when generating the interface, multifaceted systems such as Flamenco often take more than 5 seconds to show its webpages.
We propose our HyperFacet middleware to apply to existing multifaceted systems that uses binary operations to replace complex SQL queries. It transfers the attributes of the items into binary arrays and furthermore hash them for better efficiency. With the characteristic of binary arrays, we also designed a fast recommendation utility that retrieve items with similar attributes in a very efficient method.
The systems applying our middleware need only small modification. Moreover, it costs little in memory and preprocessing time. As a result, our solution obviously reduces the response time of the system in three different type of data distributions, and performs more steady in various situations.
