Exploratory search is a specialization of information exploration which represents the activities carried out by searchers who are either: * a) unfamiliar with the domain of their goal (i.e. need to learn about the topic in order to understand how to achieve their goal) * b) unsure about the ways to achieve their goals (either the technology or the process) * c) or even unsure about their goals in the first place. Consequently, exploratory search covers a broader class of activities than typical information retrieval, such as investigating, evaluating, comparing, and synthesizing, where new information is sought in a defined conceptual area; exploratory data analysis is another example of an information exploration activity. Typically, therefore, such users generally combine querying and browsing strategies to foster learning and investigation. ==History== Exploratory search is a topic that has grown from the fields of information retrieval and information seeking but has become more concerned with alternatives to the kind of search that has received the majority of focus (returning the most relevant documents to a Google-like keyword search). The research is motivated by questions like "what if the user doesn't know which keywords to use?" or "what if the user isn't looking for a single answer?" Consequently, research has begun to focus on defining the broader set of ''information behaviors'' in order to learn about the situations when a user is, or feels, limited by only having the ability to perform a keyword search. In the last few years, a series of workshops have been held at various related and key events. In 2005, the (Exploratory Search Interfaces workshop ) focused on beginning to define some of the key challenges in the field. Since then a series of other workshops have been held at related conferences: (Evaluating Exploratory Search ) at (SIGIR06 ) and (Exploratory Search and HCI ) at (CHI07 ) (in order to meet with the experts in human–computer interaction). In March 2008, an (''Information Processing and Management'' special issue ) In June 2008, the National Science Foundation sponsored an (invitational workshop ) to identify a research agenda for exploratory search and similar fields for the coming years. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Exploratory search」の詳細全文を読む スポンサード リンク
