- Abstract
- A retrieval experiment was conducted to compare on-line searching using terms opposed to citations. This is the first study in which a single data base was used to retrieve two equivalent sets for each query, one using terms found in the bibliographic record to achieve higher recall, and the other using documents. Reports on the use of a second citation searching strategy. Overall, by using both types of search keys, the total recall is increased.

- Abstract
- The history of encyclopedias and wholly new forms of encyclopedias are briefly reviewed. The possibilities and problems that hypertext presents as a basis for new forms of encyclopedias are explored. The capabilities of current systems, both experimental and commercially available, are outlined, focusing on new possibilities for authoring and design and for reading the retrieval. Examples of applications already making use of hypertext are given.

- Abstract
- The development of innovative retrieval approaches for access to visual information is among the most significant of technological, conceptual, and institutional challenges for the library and information science community. On a conceptual level, it is clear that humans employ a variety of socio-cognitive processes, as well as sensory skills, in the retrieval and evaluation of visual information. From an institutional standpoint, libraries, archives, and museums have entered into digitization projects, varying in scope and scale, the results of which are beginning to challenge the manner in which information is described, stored, and delivered. The primary goal of this issue of Library Trends is to present practitioners, researchers, and educators in the areas of library and information science, archives, and museums, as well as "imagists" working with visual resources in any setting, with a current perspective on the development of visual information retrieval and access tools. The issue's scope is limited to the analysis and retrieval of bit-mapped or raster images and video (images that are comprised of pixels of varying color information values) and does not include work with vector graphics (images encoded as numeric formulas that represent lines and curves-e.g., Geographic Information Systems [GIS]). The contributions provide perspectives from researchers and practitioners-specialists in the areas of library and information science and computer science. In planning this issue, a conscious effort was made to include a perspective on the developing foundation of visual information retrieval, as well as work representing current and experimental systems. The issue is divided into three sections-I. Foundations of Intellectual Access to Visual Information, II. Implementation and Evaluation, and III. Experimentation.
Since 1988, two issues of Library Trends have been devoted to various aspects of image and multimedia information retrieval. In each issue, the editors call for a synergy across the disciplines that develop image retrieval systems and those that utilize these systems. Stam and Giral, in the 1988 issue of Library Trends titled "Linking Art Objects and Art Information," emphasize the need for a thorough understanding of the visual information-seeking behaviors of image database users. Writing in a 1990 issue of Library Trends devoted to graphical information retrieval, Mark Rorvig takes up the fundamental issue that "what can be listed cannot always be found" and uses that statement as a framework for examining progress in intellectual access to visual information. In the ensuing decade, several critical events have unfolded that have brought about some of the needed collaboration across disciplines and have enhanced the potential for advancements in the area of visual information retrieval. First, the field of computer vision has grown exponentially within the past decade, producing tools that enable the retrieval of visual information, especially for objects with no accompanying structural, administrative, or descriptive text information. Second, the Internet, more specifically the Web, has become a common channel for the transmission of graphical information, thus moving visual information retrieval rapidly from stand-alone workstations and databases into a networked environment. Third, the use of the Web to provide access to the search and retrieval mechanisms for visual and other forms of information has spawned the development of emerging standards for metadata about these objects as well as the creation of commonly employed methods to achieve interoperability across the searching of visual, textual, and other multimedia repositories. Practicality has begun to dictate that the indexing of huge collections of images by hand is a task that is both labor intensive and expensive-in many cases more than can be afforded to provide some method of intellectual access to digital image collections. In the world of text retrieval, text "speaks for itself" whereas image analysis requires a combination of high-level concept creation as well as the processing and interpretation of inherent visual features. In the area of intellectual access to visual information, the interplay between human and machine image indexing methods has begun to influence the development of visual information retrieval systems. Research and application by the visual information retrieval (VIR) community suggests that the most fruitful approaches to VIR involve analysis of the type of information being sought, the domain in which it will be used, and systematic testing to identify optimal retrieval methods.
Section I-"Foundations of Access to Visual Information"-is intended to provide a background in the familiar concept-based approach to describing and retrieving images, as well as the more recently developed content-based approach to visual information retrieval using inherent features such as color, shape, and texture. The importance of the articles in this section cannot be over-emphasized. In their own way, each clarifies the inevitable need to consider the interaction between high-level semantic concepts and inherent content in VIR. Content retrieval, the area which is newest to the library and information science community, will demand increased understanding and analysis in order to determine its value to users as we build more robust and lasting visual information retrieval systems. The authors in section I emphasize the need for a greater understanding of the interplay between concept-based indexing (performed by humans) and the automatic or semi-automatic process of indexing an image or a video sequence (using software) based on inherent image attributes. Section II-"Implementation and Evaluation"-focuses more specifically on the implementation and evaluation of visual information retrieval systems with cultural heritage information since this is a primary interest of libraries, museums, and archives. Section III-"Experimental Approaches"-presents articles describing three research projects that examine various aspects of image or combined image and text retrieval methods. The work represented in this issue suggests that a number of professional communities are contributing different but essential components to the development of useful and innovative image retrieval systems. In spite of the great technology strides in multimedia, image database developers and image content holders continue to grapple with the fluid issues of organization, access, retrieval, delivery, and representation. Computers now enable users to incorporate images of art and other works into their own personal information contexts-images which have for centuries been a powerful and efficient medium for conveying landmark concepts, emotions, and events. The concomitant challenge for libraries, museums, and archives also involves a shift-not only in technology and practice but also in focus-i.e., to equip ourselves with an effective understanding of the similarities and differences between text and multimedia information retrieval, and to use this knowledge as a foundation for developing effective access and archiving methods.

- Abstract
- The paper summarizes the results of an on-line survey which was executed 2010 in german archives of all branches. The survey focused on metadata and used metadata standards for the annotation of audiovisual media like pictures, audio and video files (analog and digital). The findings motivate the question whether archives are able to collaborate in projects like europeana if they do not use accepted standards for their orientation. Archives need more resources and archival staff need more training to execute more complex tasks in an digital and semantic surrounding.

- Abstract
- The two seemingly conflicting tendencies, synergy and divergence, are both fundamental to the advancement of any science. Their interplay defines the demarcation line between application-oriented and theoretical research. The papers in this festschrift in honour of Peter Hellwig are geared to answer questions that arise from this insight: where does the discipline of Computational Linguistics currently stand, what has been achieved so far and what should be done next. Given the complexity of such questions, no simple answers can be expected. However, each of the practitioners and researchers are contributing from their very own perspective a piece of insight into the overall picture of today's and tomorrow's computational linguistics.

- Abstract
- In many companies, the use of information retrieval systems is substantially augmented by 'word-of-mouth' communication. In such a system individuals use their valuable experience and understanding of one another's needs in order to achieve a very precise filtering and directing of information. The perception which these individuals bring to bear represent a form of corporate knowledge. The RADA (Research And Development Advisor) system has been developed at the University of Sunderland to perform information retrieval in a research and development environment. A component is currently being developed to emulate a word-of-mouth system. This work involves a combination of techniques and themes from the areas of Artificial Intelligence and Computer Supported Cooperative Work to provide a design for a system which will provide a more intuitive form of information storage and retrieval. This paper will describe the architecture and objectives of the RADA system, and report on progress to date with the work

- Rez. in: Machine translation review: 1999, no.10, S.26-27 (D. Lewis): "Cross Language Information Retrieval (CLIR) addresses the growing need to access large volumes of data across language boundaries. The typical requirement is for the user to input a free form query, usually a brief description of a topic, into a search or retrieval engine which returns a list, in ranked order, of documents or web pages that are relevant to the topic. The search engine matches the terms in the query to indexed terms, usually keywords previously derived from the target documents. Unlike monolingual information retrieval, CLIR requires query terms in one language to be matched to indexed terms in another. Matching can be done by bilingual dictionary lookup, full machine translation, or by applying statistical methods. A query's success is measured in terms of recall (how many potentially relevant target documents are found) and precision (what proportion of documents found are relevant). Issues in CLIR are how to translate query terms into index terms, how to eliminate alternative translations (e.g. to decide that French 'traitement' in a query means 'treatment' and not 'salary'), and how to rank or weight translation alternatives that are retained (e.g. how to order the French terms 'aventure', 'business', 'affaire', and 'liaison' as relevant translations of English 'affair'). Grefenstette provides a lucid and useful overview of the field and the problems. The volume brings together a number of experiments and projects in CLIR. Mark Davies (New Mexico State University) describes Recuerdo, a Spanish retrieval engine which reduces translation ambiguities by scanning indexes for parallel texts; it also uses either a bilingual dictionary or direct equivalents from a parallel corpus in order to compare results for queries on parallel texts. Lisa Ballesteros and Bruce Croft (University of Massachusetts) use a 'local feedback' technique which automatically enhances a query by adding extra terms to it both before and after translation; such terms can be derived from documents known to be relevant to the query.
Christian Fluhr at al (DIST/SMTI, France) outline the EMIR (European Multilingual Information Retrieval) and ESPRIT projects. They found that using SYSTRAN to machine translate queries and to access material from various multilingual databases produced less relevant results than a method referred to as 'multilingual reformulation' (the mechanics of which are only hinted at). An interesting technique is Latent Semantic Indexing (LSI), described by Michael Littman et al (Brown University) and, most clearly, by David Evans et al (Carnegie Mellon University). LSI involves creating matrices of documents and the terms they contain and 'fitting' related documents into a reduced matrix space. This effectively allows queries to be mapped onto a common semantic representation of the documents. Eugenio Picchi and Carol Peters (Pisa) report on a procedure to create links between translation equivalents in an Italian-English parallel corpus. The links are used to construct parallel linguistic contexts in real-time for any term or combination of terms that is being searched for in either language. Their interest is primarily lexicographic but they plan to apply the same procedure to comparable corpora, i.e. to texts which are not translations of each other but which share the same domain. Kiyoshi Yamabana et al (NEC, Japan) address the issue of how to disambiguate between alternative translations of query terms. Their DMAX (double maximise) method looks at co-occurrence frequencies between both source language words and target language words in order to arrive at the most probable translation. The statistical data for the decision are derived, not from the translation texts but independently from monolingual corpora in each language. An interactive user interface allows the user to influence the selection of terms during the matching process. Denis Gachot et al (SYSTRAN) describe the SYSTRAN NLP browser, a prototype tool which collects parsing information derived from a text or corpus previously translated with SYSTRAN. The user enters queries into the browser in either a structured or free form and receives grammatical and lexical information about the source text and/or its translation.
The retrieved output from a query including the phrase 'big rockets' may be, for instance, a sentence containing 'giant rocket' which is semantically ranked above 'military ocket'. David Hull (Xerox Research Centre, Grenoble) describes an implementation of a weighted Boolean model for Spanish-English CLIR. Users construct Boolean-type queries, weighting each term in the query, which is then translated by an on-line dictionary before being applied to the database. Comparisons with the performance of unweighted free-form queries ('vector space' models) proved encouraging. Two contributions consider the evaluation of CLIR systems. In order to by-pass the time-consuming and expensive process of assembling a standard collection of documents and of user queries against which the performance of an CLIR system is manually assessed, Páriac Sheridan et al (ETH Zurich) propose a method based on retrieving 'seed documents'. This involves identifying a unique document in a database (the 'seed document') and, for a number of queries, measuring how fast it is retrieved. The authors have also assembled a large database of multilingual news documents for testing purposes. By storing the (fairly short) documents in a structured form tagged with descriptor codes (e.g. for topic, country and area), the test suite is easily expanded while remaining consistent for the purposes of testing. Douglas Ouard and Bonne Dorr (University of Maryland) describe an evaluation methodology which appears to apply LSI techniques in order to filter and rank incoming documents designed for testing CLIR systems. The volume provides the reader an excellent overview of several projects in CLIR. It is well supported with references and is intended as a secondary text for researchers and practitioners. It highlights the need for a good, general tutorial introduction to the field."

- Abstract
- This volume contains selected papers that focus on the use of linear algebra, computational statistics, and computer science in the development of algorithms and software systems for text retrieval. Experts in information modeling and retrieval share their perspectives on the design of scalable but precise text retrieval systems, revealing many of the challenges and obstacles that mathematical and statistical models must overcome to be viable for automated text processing. This very useful proceedings is an excellent companion for courses in information retrieval, applied linear algebra, and applied statistics. Computational Information Retrieval provides background material on vector space models for text retrieval that applied mathematicians, statisticians, and computer scientists may not be familiar with. For graduate students in these areas, several research questions in information modeling are exposed. In addition, several case studies concerning the efficacy of the popular Latent Semantic Analysis (or Indexing) approach are provided.
