Abstract

ABSTRACT With the growing amount of information on users' desktops and increasing scale and complexity of intranets, Enterprise and Desktop Search are becoming two increasingly important Information Retrieval applications. While the challenges arising there are not completely different from those that the web community has faced for years, advanced web search solutions are often unable to address them properly. In this tutorial we give a research prospective on distinctive features of both Enterprise and Desktop Search, explain typical search scenarios, and review existing ranking techniques and algorithms. Keywords: Enterprise search, desktop search, user feedback, exploratory search, expert search ENTERPRIZE SEARCH In User Feedback While there are many problems that make Enterprise Search more difficult than Web Search, there are also some advantages. One such advantage is that there is typically no spam in the Enterprise. In fact, users are often inclined to cooperate with the search engine by providing their feedback and are not so concerned about privacy. Due to more manageable scale of the data, it is also much easier to utilize such feedback in the Enterprise setting than in the Web setting. This part of the tutorial is devoted to search algorithms which utilize explicit and implicit user annotations Exploratory Search Since the quality of Enterprise Search is rather limited
