Abstract

Describes the InfoAccess Project at the Univ of Saskatchewan Libraries which compared searching of manual and automated indexes by 22 undergraduate psychology students to determine their searching preferences by ranking 'Psychological abstracts' in 3 formats: print, CD-ROM and a locally mounted tape service called InfoAccess. Their satisfaction regarding the physical environment, equipment, and instructional aids was also recorded. Users preferred to search with CD-ROM, but found InfoAccess to be an acceptable alternative

Abstract

Examines the implementations of document ranking based on inverted files. Studies three heuristic methods for implementing the term frequency X inverse document frequency weighting strategy. The basic idea of the heuristic methods is to process the query terms in an order so that as many top documents as possible can be identified without processing all of the query terms. The heuristics were evaluated and compared. The results show improved performance. Two methods for estimating the retrieval accuracy were studied. All experiments were based on four test collection made available with the SMART system

Abstract

Reviews research which aims to improve the ways in which documents are presented to the user within the MenUSE (Menu based User Search Engine) search intermediary system. MenUSE is an advanced intermediary system for end user searching of bibliographic databases originating in CANSEARCH, a prototype intermediary system that used an expert systems approach to generate searches in cancer therapy related information retrieval from MEDLINE. In particular it investigates ways in which the order of presentation of documents can be made more effective. Discusses alternative schemes for document reordering, the main emphasis being on the provision of relevance ranking where the most relevant documents are presented to the user first. Examines the feasibility of incorporating such ranking techniques into MenUSE and compares 3 algorithms which simulate collection frequency ranking on a remote bibliographic database host using Boolean searching. Concludes that the CIRT algorithm offers the best performance. Proposes a design for an enhancement to the MenUSE system which will be the subject of user testing to verify the effectiveness of ranking in MenUSE

Abstract

The performance of 8 ranking algorithms was evaluated with respect to their effectiveness in ranking terms for query expansion. The evaluation was conducted within an investigation of interactive query expansion and relevance feedback in a real operational environment. Focuses on the identification of algorithms that most effectively take cognizance of user preferences. user choices (i.e. the terms selected by the searchers for the query expansion search) provided the yardstick for the evaluation of the 8 ranking algorithms. This methodology introduces a user oriented approach in evaluating ranking algorithms for query expansion in contrast to the standard, system oriented approaches. Similarities in the performance of the 8 algorithms and the ways these algorithms rank terms were the main focus of this evaluation. The findings demonstrate that the r-lohi, wpq, enim, and porter algorithms have similar performance in bringing good terms to the top of a ranked list of terms for query expansion. However, further evaluation of the algorithms in different (e.g. full text) environments is needed before these results can be generalized beyond the context of the present study

Abstract

Proposes a new idea of searching under the multi-engine search architecture to overcome the problems associated with relevance ranking. These include clustering of the search results and extraction of co-occurence keywords, which, with the user's feedback, better refines the query in the searching process. The system also provides the construction of the concept space to gradually customize the search tool to fit the usage for the user at the same time

Abstract

Presents WebTagger, an implemented prototype of a personal book marking service that provides both individuals and groups with a customisable means of organizing and accessing Web-based information resources. The service enables users to supply feedback on the utility of these resources relative to their informatio needs, and provides dynamically updated ranking of resources based on incremental user feedback. Individuals may access the service from anywhere on the Internet and require no special software. The service simplifies the process of sharing URLs within groups, in comparison with manual methods involving email. The underlying bookmark organization scheme is more natural and flexible than current hierarchical schemes supported by the major Web browsers and enables rapid access to stored bookmarks

Abstract

The WebQuery system offers a powerful new method for searching the Web based on connectivity and content. Examines links among the nodes returned in a keyword-based query. Rankes the nodes, giving the highest rank to the most highly connected nodes. By doing so, finds hot spots on the Web that contain information germane to a user's query. WebQuery not only ranks and filters the results of a Web query; it also extends the result set beyond what the search engine retrieves, by finding interesting sites that are highly connected to those sites returned by the original query. Even with WebQuery filering and ranking query results, the result set can be enormous. Explores techniques for visualizing the returned information and discusses the criteria for using each of the technique

Abstract

The Malay language is widely used in Malaysia, Indonesia and brunei. The growth in the number of documents written in Malay justifies the need for a document retrieval system for that language. Describes the implementation of a bilingual Malay and English full text document retrieval systems: SIStem capaian DOkumen Multilingua (SISDOM), by the Kebangsaan University Malaysia. The system incorporates many facilities for users, including the choice of search techniques, browsing of retrieved documents, and ranking of documents

Abstract

Investigates document ranking methods in thesaurus-based Boolean retrieval systems and proposes a new thesaurus-based ranking algorithm, the Extended Relevance (E-Relevance) algorithm. The E-Relevance algorithm integrates the extended Boolean model and the thesaurus-based relevance algorithm. Since the E-Relevance algorithm has all the desirable properties of previous thesauri-based ranking algorithms. It also ranks documents effectively by uisng terms dependence information from the thesaurus. Through performance comparison shows that the proposed algorithm achieved higher retrieval effectiveness than the others proposed earlier
