Abstract

Describes a novel visual user interface, WebIFQ (Web-In-Frame-Query), to assist users in specifying queries and visualising query criteria including document metadata, strucutres, and linkage information. WebIFQ automatically generates corresponding query statements for WebDB. As a result, users are not required to be aware of underlying complex schema design and language syntax. WebDB supports automated query relaxation to include additional terms related by semantic or co-occurence relationship. WebIFQ can facilitate users to reformulate queries perpetually in an interactive mode

Abstract

Those seeking information from the Internet often start from a search engine, using either its organised directory structure or its text query facility. In response to the difficulty in identifying the most relevant pages for some information needs, many search engines offer Boolean text matching and some, including Google, AltaVista and HotBot, offer the facility to integrate additional information into a more advanced request. Amongst web users, however, it is known that the employment of complex enquiries is far from universal, with very short queries being the norm. It is demonstrated that the gap between the provision of advanced search facilities and their use can be bridged, for specific information needs, by the construction of a simple interface in the form of a website that automatically formulates the necessary requests. It is argued that this kind of resource, perhaps employing additional knowledge domain specific information, is one that could be useful for websites or portals of common interest groups. The approach is illustrated by a website that enables a user to search the individual websites of university level institutions in European Union associated countries.

Abstract

Focuses on the user and human-computer interaction (HCI) aspects of the research based on the Okapi text retrieval system. Describes 3 experiments using different approaches to query expansion, highlighting the relationship between the functionality of a system and different interface designs. These experiments involve both automatic and interactive query expansion, and both character based and GUI (graphical user interface) environments. The effectiveness of the search interaction for query expansion depends on resolving opposing interface and functional aspects, e.g. automatic vs. interactive query expansion, explicit vs. implicit use of a thesaurus, and document vs. query space

Abstract

An online library catalogue served as a testbed to evaluate an interactive query expansion facility based on relevance feedback for the Okapi probabilistic term weighting retrieval system. The facility was implemented in a graphical user interface (GUI) environment using a game-board metaphor for the search process, and allowed searchers to select candidate terms extracted from relevant retrieved itms to reformulate queries. The take-up of the interactive query expansion option was found to be lower, and its retrieval performance less effective, compared to previous tests featuring automatic query expansion. Contributory factors including the number, presentation and source of terms are discussed

Abstract

The nature of search requirements is perceived to be changing, fuelled by a growing dissatisfaction with the marginal accuracy and often overwhelming quantity of results from simple keyword matching techniques. Traditional search interfaces fail to acknowledge and utilise the implicit underlying structure present within a typical keyword query. Faceted structure can (and should) perform a significant role in this area - acting as the basis for mediation between searcher and indexer, and guiding query formulation and reformulation by interactively educating the user about the native domain. This paper discusses the possible benefits of applying faceted knowledge organization systems to enhance query structure, query visualisation and the overall query process, drawing an the outcomes of a recently completed research project.

Abstract

Ausgehend von einer Diskussion der Gestaltungskonzeptionen und der Leistungsfähigkeit heutiger Volltext-Retrieval-Systeme wird ein Überblick über den Leistungsumfang des für die Aufbereitung und Präsentation von Textinformation zuständigen Systems TWRM-TOPOGRAPHIC gegeben. TWRM-TOPOGRAPHIC ist Teil eines neuartigen Informationssystems, das sich auf inhaltsorientierte Repräsentation von Volltexten stützt. Die beiden wesentlichsten Leistungsmerkmale von TWRM-TOPOGRAPHIC sind die graphische Retrievaldialogführung und die flexible, situationsgerechte Aufbereitung und Präsentation von Textwissen: Die Dialogführung erlaubt dem Benutzer die direkte Navigation in den auf dem Bildschirm graphisch dargestellten Wissensstrukturen, die Selektion dargestellter Objekte zur Formulierung einer Query sowie das Wechseln des Abstraktionsniveaus der dargestellten Textinformation. Die Aufbereitung und die Präsentation von Textwissen sind kognitiv-ergonomisch begründet und berücksichtigen sowohl die begrenzte Aufnahmekapazität der Benutzer als auch die Bedeutung der zeitlichen Anordnung von Informationseinheiten für die Wahmehmungs- und Gedächtnisleistung der Rezipienten. Textwissen wird in unterschiedlichen Abstraktionsstufen präsentiert: von einer sehr generischen Ebene über Wissensgraphen, automatisch generierten Abstracts bis zur diskursiven Form der Textpassage. Die Generierungskomponente des Systems leistet einen Beitrag zum situationsgerechten Systemverhalten dadurch, daß sie aus semantischen Text-Repräsentationsstrukturen unter Berücksichtigung textueller Wohlgeformtheitsbedingungen benutzerangepaßte Abstracts mit unterschiedlichem Themenschwerpunkt und variabler Ausführlichkeit produziert. Die Erprobung verschiedener LayoutVerfahren im Projekt TWRM-TOPOGRAPHIC wird durch ein flexibles, objektorientiert spezifiziertes User-Interface-Mangagement-System (UIMS) unterstützt, dessen Objektklassen und deren Interaktionsmöglichkeiten vorgestellt werden. Die Darstellung des Systems wird mit einem ausführlichen Dialogbeispiel abgeschlossen, das die Funktion des Interface und die Wirkung der drei zentralen Operatoren (Select, Zoom und Browse) im Retrievaldialog illustriert.

Abstract

The study adopts a naturalistic approach to investigate users' interaction with a browsable MeSH (medical subject headings) display designed to facilitate query construction for the PubMed bibliographic database. The purpose of the study is twofold: first, to test the usefulness of a browsable interface utilizing the principle of faceted classification; and second, to investigate users' preferred query submission methods in different problematic situations. An interface that incorporated multiple query submission methods - the conventional single-line query box as well as methods associated the faceted classification display was constructed. Participants' interactions with the interface were monitored remotely over a period of 10 weeks; information about their problematic situations and information retrieval behaviors were also collected during this time. The traditional controlled experiment was not adequate in answering the author's research questions; hence, the author provides his rationale for a naturalistic approach. The study's findings show that there is indeed a selective compatibility between query submission methods provided by the MeSH display and users' problematic situations. The query submission methods associated with the display were found to be the preferred search tools when users' information needs were vague and the search topics unfamiliar. The findings support the theoretical proposition that users engaging in an information retrieval process with a variety of problematic situations need different approaches. The author argues that rather than treat the information retrieval system as a general purpose tool, more attention should be given to the interaction between the functionality of the tool and the characteristics of users' problematic situations.

Abstract

Proposes a method of organizing documents based on the concepts of aggregation and hierarchies and a graphical user interface to provide a more intuitive form of Boolean query. The design is based on mapping the nodes of the aggregation hierarchy to Boolean intersection operations, mapping the nodes of the generalization hierarchy Boolean intersection operations (?), and providing a concrete, graphical, manipulable representation of both these node types. A working prototype interface was constructed and evaluated experimentally using 16 subjects against a classical command-line Boolean query interface. The graphical interface produced less than one-tenth of the errors of the textual interface, on average. Significant differences in time spent specifying queries were not found. Makes observations and comments to provide guidance for designers

Abstract

Describes the OKAPI projects and OKAPI's development as an experimental online catalogue system over 10 years, first at the University of Westminster (formerly the Polytechnique of Central London) and subsequently at City University, London. The 1st OKAPI project in 1984 introduced 'best match' retrieval and focused on the user interface design. The 2nd investigated word stemming, spelling correction and cross reference tables as retrieval aids. A comparative study of 2 library catalogues was undertaken in 1987, while in 1988 query expansion and relevance feedback were introduced and evaluated by laboratory tests. In 1990 live evaluation of automatic query expansion was carried out and in 1993 subject enhancement of bibliographic records was investigated. The latest project has examined the design of a graphical user interface to support interactive query expansion. Discusses the research and evaluation of each project

Abstract

Reports on work in progress to define an object oriented model of a probabilistic information retrieval system (OKAPI), the central component of which is the query itself. Considers how to represent queries both internally and at the user interface level, and their relationship with other components of the model. The model will form the basis of a configurable user interface, which allows controlled experiments to be undertaken, and could be adapted to the needs of different users accessing different databases. Implementation will involve the use of a high level interpreted scripting language for overall control, communicating with an internal model and an interface model, designed and developed using object oriented techniques

Abstract

MedLine Search Assistant is a new interface for MEDLINE searching. The interface is designed to (1) visualize boolean query building process, (2) extract descriptors (MeSH terms) automatically from the retrieved documents and list them in the order of their occurrence frequencies, (3) guide the user's query modification process through the display of the number of hits, and (4) allow the user to "pick-and-choose" from a list of related MeSH terms to construct search queries. MedLine Search Assistant improves both search precision and recall by helping the user convert a free text search to a controlled vocabulary-based search in a visual environment

Abstract

View based searching and multi view searching using HIBROWSE proposes a new paradigm for information retrieval from bibliographic databases and database management systems. The paradigm replaces command line and form based interaction with query specification and interaction which requires the user to identify views relating to query facets of the subject of their query. Attempted to apply techniques from human-computer interaction design in the development, construction and usability evaluation of a view based searching system for a very large bibliographic database. As the development of the HIBROWSE system had been in progress before usability became a major concern, as well as the class of system being developed, greater progress towards improved usability was made by adopting a less structured development life-cycle. Examined the usefulness of a number of usability evaluation methods in the context of trying to determine the usability of designs in interactive information retrieval systems. Measurement of the subjective usability of prototypes reinforced the finding of users' difficulties in forming a useful account of the system behaviour and functionality from the training material provided, highlighted some aspects of the system that could be improved, and the greater usability of the HIBROWSE prototypes over an extant commercial bibliographic database system

Abstract

The ENQUIRE project forms part of a series of investigations on query expansion in the Okapi experimental text retrieval system. A configurable user interface was implemented as an evaluative tool and tested in two locations on two different databases: the library catalogue of The London Business SChool and the computing section of INSPEC. The system offered a range of possible strategies based on thesaural terms for reformulating queries. These could be initiated automatically by the system or interactively with the user. The formative phase of the evaluation established the appropriateness and usability of the interface as well as users' perceptions of the underlying functionality. The aim of the large scale field trial was to determine to what extent user would select thesaural terms suggested by the system to reformulate queries, and to evaluate the effectiveness of a new dynamic form of query expansion implemented for this project

Abstract

This article investigates a new, effective browsing approach called metabrowsing. It is an alternative for current information retrieval systems, which still face six prominent difficulties. We identify and classify the difficulties and show that the metabrowsing approach alleviates the difficulties associated with query formulation and missing domain knowledge. Metabrowsing is a high-level way of browsing through information: instead of browsing through document contents or document surrogates, the user browses through a graphical representation of the documents and their relations to the domain. The approach requires other cognitive skills from the user than what is currently required. Yet, a user evaluation in which the metabrowsing system was compared with an ordinary query-oriented system showed only some small indicatory differences in effectiveness, efficiency, and user satisfaction. We expect that more experience with metabrowsing will result in a significantly better performance difference. Hence, our conclusion is that the development of new cognitive skills requires some time before the technologies are ready to be used.

Abstract

Past research has proved that graphical user interfaces (GUIs) can significantly improve the effectiveness of the information access task. Our work is based on the consideration that structured document retrieval requires different user graphical interfaces from standard information retrieval. In structured document retrieval a GUI has to enable a user to query, browse retrieved documents, provide query refinement and relevance feedback based not only on full documents, but also on specific document parts in relation to the document structure. In this paper, we present a new GUI for structured document retrieval specifically designed for hierarchically structured documents. A user task-oriented evaluation has shown that the proposed interface provides the user with an intuitive and powerful set of tools for structured document searching, retrieved list navigation, and search refinement.
