An NF2 Relational Interface For Document Retrieval, Restructuring and Aggregation
Authors: Kalervo Järvelin, Timo Niemi
Venue: SIGIR
Year: 1995

Complex documents are used in many environments, e.g., information retrieval (IR). Such documents contain subdocuments, which may contain further subdocuments, etc. Powerful tools are needed to facilitate their retrieval, restructuring, and analysis. Existing IR systems are poor in complex document restructuring and data aggregation. However, in practice, IR system users would often want to obtain aggregation information on subdocuments of complex documents. In this paper we address this problem and provide a truly declarative and powerful interface for the users. Our interface is based on the non-fkst-normal-form (NF2) relational model. It allows intuitive and systematic modeling of complex documents.
Efficient Recompression Techniques for Dynamic Full-Text Retrieval Systems
Authors: Shmuel T. Klein
Venue: SIGIR
Year: 1995

An efficient variant of an optimal algorithm is presented, which, in the context of a large dynamic fulltext information retrieval system, reorganizes data that has been compressed by an on-the-fly compression method based on LZ77, into a more compact form, without changing the decoding procedure. The algorithm accelerates a known technique based on a reduction to a graph-theoretic problem, by reducing the size of the graph, without affecting the optimality of the solution. The new method can thus effectively improve any dictionary compression scheme using a static encoding method.

A New Character-based Indexing Organization using Frequency Data for Japanese Documents
Authors: Yasushi Ogawa, Masajiro Iwasaki
Venue: SIGIR
Year: 1995

A character based indexing is preferable for Japanese IR systems since Japanese words are not segmented. This paper proposes a new character indexing method to enhance our previous method which divided character pair index entries into disjoint groups based on character classes. Since frequency data is used to determine hashed entries for character pairs and to establish a special string index, both search speed and precision are improved. Moreovel<, bit strings are managed using small and large blocks, so registration and retrieval are accelerated. Experiments using patent abstracts showed these proposals are quite effective.

Evaluation of Evaluation in Information Retrieval
Authors: Tefko Saracevic
Venue: SIGIR
Year: 1995

Evaluation is a major force in research, development and applications related to information retrieval (IR). This paper is a critical and historical analysis of evaluations of IR systems and processes. Strengths and shortcomings of evaluation efforts and approaches are discussed. together with major challenges and questions. A limited comparison is made with evaluation in experts systems and Online Public Access Catalogs (OPACS). Evaluation is further analyzed in relation to the broad context and specific problems addressed. Levels of evaluation are identified and contrasted. most IR evaluations were concerned with the processing level, but others were conducted at the output, users and use, and social levels. A major problem is the isolation of evaluations at a given level. Issues related to systems under evaluation, and evaluation criteria, measures, measuring instruments, and methodologies are examined. A general point is also considered: IR is mcreasmgly imbedded into many other applications, such as the Internet or digital libraries. Little evaluation in the traditional IR sense is undertaken in relation to these applications. The challenges are to inte~ate IR evaluations from different levels and to incorporate evaluation in new applications. explosion is a complex social, cognitive, cultural, and communication problem, and not just a technical problem. Thus, at its base IR is an activity oriented toward problems with the same (social, cognitive, communication) characteristics. Ultimately, IR exists as a social activity to link 101-108.
Design of a Reusable IR Framework
Authors: Gabriele Sonnenberger, Hans-Peter Frei
Venue: SIGIR
Year: 1995

In this paper, we describe the design of a reusable IR framework, called FIRE, that is being implemented to facilitate the development of IR systems. In addition, FIRE is designed to support the experimental evaluation of both indexing and retrieval techniques. First, we discuss the development of reusable software in the IR domain and derive essential criteria for the design of an IR framework. Next, we sketch the object model developed for FIRE. We present the basic concepts and their modeling and show how the components interact when performing indexing and retrieval tasks. 1. Introduction Everyday information is heterogenous and usually consists of structured and unstructured parts. In addition, it may be composed of different media. Furthermore, information is invariably embedded in a context and is associated with additional information. In the past the focus in information retrieval (IR) has been on text, which was mostly considered to be unstructured. Recently, different meth...
Dissemination of Collection Wide Information in a Distributed Information Retrieval System
Authors: Charles L. Viles, James C. French
Venue: SIGIR
Year: 1995

We find that dissemination of collection wide information (CWI) in a distributed collection of documents is needed to achieve retrieval effectiveness comparable to a centralized collection. Complete dissemination is unnecessary. The required dissemination level depends upon how documents are allocated among sites. Low dissemination is needed for random document allocation, but higher levels are needed when documents are allocated based on content. We define parameters to control dissemination and document allocation and present results from four test collections.

Improving the Information Search Interface: the case for two search models
Authors: Sylvia Willie, Peter Bruza
Venue: SIGIR
Year: 1995

Computerised mfonnation spaces evolved using the Boolean logic paradigm for retrieval of their stored mfonnatitm. While many studies have looked at ways to improve training to enable users to create queries appropriate to their infomlation need, little attention has been paid to users' cognitive models of the mfonnation Tlus research shows that when people can illustrate their queries graplucally, they have at least two quite different mental models. These incorporate the information space they are working with and the particular approach applied to their search This paper presents the tlndings to date and indicates the additional avenues which we believe warrant investigation.
Incremental Relevance Feedback for Information Filtering
Authors: James Allan 0001
Venue: SIGIR
Year: 1996

We use data from the TREC routing experiments to explore how relevance feedback can be applied incrementally-using a few judged documents each tim~to achieve results that are as good as if the feedback occurred in one paas. We show that relatively few judgments are needed to get highquality results. We also demonstrate methods that reduce the amount of information archived from past judged documents without adversely tiecting effectiveness. A novel simulation shows that such techniques are useful for handling long-standing queries with drifting notions of relevance. 1

The Design of a High Performance Information Filtering System
Authors: Timothy A. H. Bell, Alistair Moffat
Venue: SIGIR
Year: 1996

A high performance information filtering system has three main requirements: it must be effective in supplying users with useful information, it must do so in a timely fashion, and it must be able to handle a large throughput of information and a large number of user profiles efficiently. These three requirements pose a difficult problem, and to our knowledge no existing system is capable of meeting all three. In this paper we describe a system which combines a number of techniques from other information retrieval and filtering systems, and is capable of providing high performance on a typical workstation platform. We provide estimates of computing resource usage, and show that our system is also scalable.

Venue: SIGIR
Year: 1996

Information explosion across the Internet and elsewhere offersaccess toanincreasing number of document collections. In order for users to effectively access these collections, information retrieval (IR) systems must provide coordinated, concurrent, and distributed access. In this paper, we describe a fully functional distributed IR system based on the Inquery unified IR system. To refine this prototype, we implement a flexible simulation model that analyzes perwhich a large number of clients and servers communicate. 1 This model allows us to investi@.e systems that vary from our implementation.

Cross-linguistic Information Retrieval Workshop (Abstract)
Authors: Gregory Grefenstette
Venue: SIGIR
Year: 1996

Wheel running performed by rats is reinforcing, rewarding and possibly addictive. In this study we analyzed if wheel running could affect ethanol preference. Lewis rats, known to be both addiction-prone and to develop an excessive wheel running behavior, were given access to ethanol in a two-bottle free-choice paradigm. The animals reached a high and stable ethanol intake after 5 weeks. In the next phase, rats were subjected to ethanol withdrawal for 1, 2 or 4 weeks with or without access to running wheels. Finally animals were again given access to ethanol in the same two-bottle free-choice paradigm, combined with access to running wheels. The rats that ran in running wheels during 1 or 2, but not 4, weeks of ethanol withdrawal increased both ethanol intake and preference as compared with the control group that did not have access to the wheels. Previous studies have demonstrated that low doses of morphine increases ethanol preference. Here we show that also running potentiates ethanol intake and preference. Thus, running which shares many of the reinforcing properties with addictive drugs appears to potentiate rats to an increased preference for ethanol. Our results describe a behavioral interaction where running increases ethanol consumption.

Method Combination For Document Filtering
Authors: David A. Hull, Jan O. Pedersen 0001, Hinrich Schütze
Venue: SIGIR
Year: 1996

There is strong empirical and theoretic evidence that combination of retrieval methods can improve performance. In this paper, we systematically compare combination strategies in the context of document filtering, using queries from the Tipster reference corpus. We find that simple averaging strategies do indeed improve performance, but that direct averaging of probability estimates is not the correct approach. Instead, the probability estimates must be renormalized using logistic regression on the known relevance judgements. We examine more complex combination strategies but find them less successful due to the high correlations among our filtering methods which are optimized over the same training data and employ similar document representations. 1 Introduction A text filtering system monitors an incoming document stream and selects documents identified as relevant to one or more of its query profiles. If profile interactions are ignored, this reduces to a number of independent bina...
A Deductive Data Model for Query Expansion
Authors: Kalervo Järvelin, Jaana Kristensen, Timo Niemi, Eero Sormunen, Heikki Keskustalo
Venue: SIGIR
Year: 1996

We present a deductive data model for conceptbased query expansion. It ]s based on three abstraction levels: the conceptual, linguistic and occurrence levels. Concepts and relationships among them are represented at the conceptual level. The expression level represents natural language expressions for concepts. Each expression has one or more matchmg models at the occurrence level. The models specify the matching of the expression in database Indices built in varying ways. The data model supports a concept-based query expansion and formulation tool, the ExpansionTool, for heterogeneous IR system envirom ments, Expansion is controlled by adjustable matching reliability.
Efficient Transaction Support for Dynamic Information Retrieval Systems
Authors: Mohan Kamath, Krithi Ramamritham
Venue: SIGIR
Year: 1996

To properly handle concurrent accesses to documents by updates and queries in information retrieval (IR) systems, efforts are on to integrate IR features with database management system (DBMS) features. However, initial research has revealed that DBMS features optimized for traditional databases, display degraded performance while handling text databases. Since efficiency is critical in IR systems, infrastructural extensions are necessary for several DBMS features, transaction support being one of them. This paper focuses on developing efficient transaction support for IR systems where updates and queries arrive dynamically, by exploiting the data characteristics of the indexes as well as of the queries and updates that access the indexes. Results of performance tests on a prototype system demonstrate the superior performance of our algorithms.
