Week 5 Muddiest Point
Is the dominance of the exact match model (boolean retrieval) a form of job security for librarians? Our book says that the Lexis-Nexis vector space retrieval returned better results than expert librarians employed by Lexis-Nexis for boolean retrieval reference services. Are there empirical studies of the relevance of results with each model? I don't understand why those professional searchers still have a job after what the book mentioned. Or, at least, why haven't they transitioned to performing natural language searches for patrons after engaging them to find their information need?
At my internship, I use boolean retrieval over several medical databases. And more often than not, I get frustrated after an hour of fruitless searching and google it, with perfect results.
