In this report, we investigate how retrieving information can be improved through task-related indexing of documents based on ontologies. Different index types, varying from content-based keywords to structured task-based indexing ontologies, are compared in an experiment that simulates the task of creating instructional material from a database of source material. To be able to judge the added value of task- and ontology-related indexes, traditional information retrieval performance measures are extended with new measures reflecting the quality of the material produced with the retrieved information. The results of the experiment show that a structured task-based indexing ontology improves the quality of the product created from retrieved material only to some extent, but that it certainly improves the efficiency and effectiveness of search and retrieval and precision of use (AU) |

The goal is to deepen the knowledge of both sides of the abstract/ing topic: abstracting variables and abstract attributes. Six abstracting variables (representing abstract, represented source, abstracting means, documentary goal, cognitive domain and user needs) and eight abstract attributes (representativeness, comprehensiveness, usefulness, accuracy, consistency, coherence, density and perceived quality) are proposed and weighted. While abstracting means is uncovered as the main abstracting variable, the representativeness and accuracy attributes stand out, and usefulness, comprehensiveness, consistency, coherence and density are regarded as the basic ones. The feedback of this quality model is performed by the perceived quality attribute, which depends exclusively on users. |

A cognitive view of the situational dynamism of user-centered relevance estimation |

Article included in a special issue on relevance. Research aimed at observing the interaction between users and information systems has traditionally been diminished by the difficulties associated with controlling the situational dynamism of user centred relevance estimation. Identifies a methodology for operationalizing this concept from a cognitive view. Proposes a framework which allows the user to articulate the cognitive schema that is used for estimating relevance and a methodology for recording the changes to this schema that occur during the information retrieval interaction.
