Forty end-users with individual information problems from an academic environment were observed, interacting with six professional intermediaries searching on their behalf in large operational systems. Conceptual categories of users' reasons for assigning particular value ratings on the value of search results and relationships between these…

Presents a stratified model of information retrieval interaction that views interaction as a dialog between participants (user and computer) through an interface. Discusses traditional and interaction models, and extension to relevance, user modeling, search term selection, and types of feedback in information retrieval. (AEF)

Reports a preliminary investigation into the man-machine interaction aspects of online searching, including the methodology developed for observing and recording man-machine interface in the use of online information retrieval systems. Three references are cited, and a bibliography lists 16 sources. (FM)

Investigates information retrieval from hypertext on the World Wide Web. Significant main and interaction effects were found for both link density (number of links per display) and display format (paragraphs or lists) on search performance. Low link densities displayed in list format produced the best overall results. Expert browsers performed…

On the 14th and 15th of January, 1971, a workshop on The User Interface for Interactive Search of Bibliographic Data Bases was held in Palo Alto. The participants were provided in advance with a challenge paper and with a number of papers prepared in response to that challenge. The Workshop sessions themselves were devoted exclusively to focussed…

Describes an expert system which provides users who have information needs with terms to express search queries; introduces principles on which the system's behavior is based; describes the system's main procedures and decision rules; presents an example of system use; and outlines possible improvements in system search and evaluation procedures.…

Examines traditional and interactive models that have emerged in information retrieval (IR), and proposes an interactive IR model based on different levels in the interactive processes. Analyzes strengths and weaknesses of the traditional model. Concludes with general remarks on the state of IR interaction research. (Author/AEF)

The first interactive (on-line) computerized use of the ERIC files by the U.S. Office of Education is reported in the form of an evaluation of the DIALOG system conducted at the ERIC Clearinghouse for Educational Media and Technology. Descriptions of the purposes of the study, of the DIALOG system (developed by Lockheed Missiles and Space Co.),…

Describes a model of information retrieval as social interaction, which distinguishes between three types of information interaction goals: (1) task-oriented; (2) topically oriented; and (3) those centered around situation assessment (SA). Results suggest that SA is an important cognitive activity in new information retrieval environments; SA…

Lists and discusses factors affecting presearch interviews; common elements of the interview; and components of interviews with new or infrequent users, experienced users of search services, and on-site users. Do's and don'ts for library staff members during a search and skills and attributes for effective presearch interviews are also listed.…

Discusses changes of focus, or interaction shifts, (readily observed in mediated database searching) between search intermediaries and users during information retrieval interactions. Presents results in terms of frequency of shifts in each interaction; classification scheme for shifts; frequency of shifts for each class; and intensity of focus on…

Explores the concepts of interaction and interactivity presented in different theoretical models in the fields of human-computer interaction (HCI) and information-seeking/searching behavior, and relates these to information retrieval (IR) research. Suggests that interaction in HCI is primarily concerned with establishing a user/system dialogue at…

Examines six cases of information-seeking behaviors--initiation, selection, exploration, formulation, collection, and presentation--as undergraduate students work through class exercises using Perseus, a Greek history information database. Describes the four themes that emerged from the learners' online protocols and interactions. (AEF)

The 12th iteration of the International Conference on Educational Data Mining (EDM 2019) is organized under the auspices of the International Educational Data Mining Society in Montreal, Canada. The theme of this year's conference is EDM in Open-Ended Domains. As EDM has matured it has increasingly been applied to open-ended and ill-defined tasks…

Examines Web users' behaviors and needs and tests a methodology for studying users' interaction with the Web. A process-tracing technique, together with tests of cognitive style, anxiety levels, and self-report computer experience, provided data on how users interact with the Web in the process of finding factual information.
