The World Wide Web is growing quickly and being applied to many new types of communications. As a basis for studying organizational communications, Yates and Orlikowski (1992; Orlikowski & Yates, 1994) proposed using genres. They de � ned genres as “typi� ed communicative actions characterized by similar substance and form and taken in response to recurrent situations ” (Yates & Orlikowski, 1992, p. 299). They further suggested that communications in a new media would show both reproduction and adaptation of existing communicative genres as well as the emergence of new genres. We studied these phenomena on the World Wide Web by examining 1000 randomly selected Web pages and categorizing the type of genre represented. Although many pages recreated genres familiar from traditional media, we also saw examples of genres being adapted to take advantage of the linking and interactivity of the new medium and novel genres emerging to � t the unique communicative needs of the audience. We suggest that Web-site designers consider the genres that are appropriate for their situation and attempt to reproduce or adapt familiar genres.

Documents on the Web can be composed of multiple Web pages, suggesting the need to consider how linking between pages affects a document's form. We illustrate this point by considering patterns of linking in a common genre of document, the Frequently Asked Questions file or FAQ. In a sample of 70 FAQs, we found four patterns of linking: no links, links within the page, links to pages on the same host and links to other hosts. We suggest that links that tie together document pieces simply recreate the already accepted FAQ genre, but links that provide navigation within the document or that link to other information sources begin to extend and adapt the FAQ genre to the needs and capabilities of the Web. 1.Introduction The World-Wide Web (or the Web) is an Internet client-server communication system for retrieving and displaying multi-media hypertext documents [1]. The Web's main advantage over earlier Internet systems is its merger of retrieval and display tools, its capacity for hand...

We report on our ongoing study of using the genre of Web pages to facilitate information exploration. By genre, we mean socially recognized regularities of form and purpose in documents (e.g., a letter, a memo, a research paper). Our study had three phases. First, through a user study, we identified genres which most/least frequently meet searchers ' information needs. We found that certain genres are better suited for certain types of needs. We identified five (5) major groups of document genres that might be used in an interactive search tool that would allow genrebased navigation. We tried to balance the following dual objectives: 1) each group should be recognizable by a computer algorithm as easily as possible 2) each group has a better chance of satisfying particular types of information needs. Finally, we developed a novel user interface for a web searching that allows genre-based navigation through three major functionalities: 1) limiting search to specified genres 2) visualizing the hierarchy of genres discovered in the search results and 3) accepting user feedback on the relevancy of the specified genres.
