Fr: choueka@bimacs.biu.ac.il (Yaacov Choueka) Re: Response database software A few months ago there were some queries in this network about the Responsa database and software. This is basically a 65-million words corpus of Rabbinical writings in Hebrew, supported by a powerful full-text retrieval system, one of the very first such systems ever developed for the Humanities; it includes most of the features pertinent to the "search engine" discussed recently, in addition to some unique components operational in the system, such as morphological processing, short-context disambiguation, local feedback, etc. A report is now available that gives full description of the database and of the retrieval software from a user's point of view. If you are interested in receiving a copy, please send me an email message with your mailing address. The report will appear soon in a book edited by A. Zampolli in honor of B. Quemada.

Fr: Peter K. Schauble Re: Specific test collections Hi, I am looking for specific test collections in order to test a retrieval model where various kinds of links between the "documents" are taken into account. By a "document" I mean a retrievable unit of information (e.g. articles, sections, HyperCard stacks, particular cards of such a stack, complex objects of an object-oriented database, etc.). So my question is: Are there, beside the classical test collections (CACM, INSPEC, MEDLARS, etc.), other collections with highly structured documents such as LaTex documents, MS-Word documents, or hypertext documents? Many thanks, Peter K. Schauble schauble@hplabs.hp.com ********** II.B.7. Fr: "John M.A. Roy" Re: Reference on signatures (hash functions) I'm looking for references on signatures (where multiple hash functions are used to generate a 'signature').

Fr: caleb!jdp@relay.eu.net (Jim Pritchett) Re: 4GL, medical office software Hello, I have a question for the "net." My wife's medical office is considering purchasing a computer system to automate the books, billing, etc. One product under consideration is from an outfit called MCC Medical System. It is written in a "Fourth Generation Language" called Thouroughbred Idol IV. Basically, it seems to be a wrapper around a database of some sort. It runs on the "infamous" SCO Xenix on a 386 box. If you have any information about MCC, Thoroughbred Idol IV, Thoroughbred Software, or anything else above, please send Email to me at the address below. (Please note, I don't get any of these newsgroups, so if you post a response I won't see it.) I apologize if I have posted inappropriately to any of these newsgroups, but these seemed to be the closest relavent groups to address my question to.

A small group of book and paper conservators are considering using this for building a relatively small specialized thesaurus. The price is certainly attractive (especially as I shall be paying for it out of my own pocket), but we would like to know if there are any particular problems we should be concerned with. Thank you very much, in advance, for our trouble.

PROJECTS IV.A.1. Fr: walker@flash.bellcore.com (Donald E. Walker) Re: ACL data collection initiative; ASCII version THE ACL DATA COLLECTION INITIATIVE There has been a recent upsurge of interest in computational studies of large bodies of text. The aim of such studies varies widely, from lexicography and studies of language change to automatic indexing methods and statistical models for improving the performance of optical character readers. In general, corpus-based studies are critical for the development of adequate models of linguistic structure and for insights into the nature of language use. However, researchers have been severely hampered by the lack of appropriate materials, and specifically by the lack of a large enough body of text on which published results can be replicated or extended by others. Recognizing this problem, the Association for Computational Linguistics has established the ACL Data Collection Initiative (ACL/DCI). It provides the aegis of a not-for-profit scientific society to oversee the acquisition and preparation of a large text corpus to be made available for scientific research at cost and without royalties. The initial goal is to acquire at least 100 million words, but we hope to gather much more. All materials submitted for inclusion in the collection will remain the exclusive property of the copyright holders (if any) for all other purposes. Each applicant for data from the ACL/DCI will be required to sign an agreement not to redistribute the data or use it for other than research purposes. Special restrictions on some materials may be necessary, but that will only be done if the restrictions do not compromise the central objective of providing general long-term access for research. The material in the ACL/DCI text corpus will be coded in a standard form based on SGML, the Standard Generalized Markup Language. Over time, we hope to be able to incorporate annotations reflecting consensually approved linguistic features like part of speech and various aspects of syntactic and perhaps semantic structure. Both the coding and the annotations will be coordinated with the work of the Text Encoding Initiative (TEI), a project to develop standards for coding and tagging a broad range of different classes of texts to facilitate data interchange and further both research and the language industries. The TEI is jointly sponsored by the ACL, the Association for Computers and the Humanities, and the Association for Literary and Linguistic Computing. Its current funding comes primarily from the National Endowment for the Humanities and the European Economic Community. Although our initial efforts will concentrate on the collection of American English, we are interacting with groups in other countries with respect to British English and other European languages, and we hope to extend the effort to other language families as well. Our current plan is to try to make available by the end of the summer about 50 million words of text, which will probably be issued on 6250 bpi 9-track magnetic tape. For this initial release we will not be concerned about the systematicity of coverage. In addition, the data will only reflect a minimal SGML formatting of the descriptive features of the text. The tapes would also include some programs, probably in C and LISP, for word concordancing and possibly other kinds of simple manipulations. In the future we hope to be exploring issues in the "ecology of language" more systematically so that we can begin to consider providing representative samples of language usage. We also would like to establish some kind of clearing house so that the results of research using the collection can be made more widely available. We have commitments from some publishers already and have some public domain text. However, we are actively soliciting material on magnetic tape and would appreciate receiving relatively large amounts that are free of copyright restrictions and can be distributed without requiring royalties. If you have texts available that we could use or know where we can obtain them, please notify us as soon as possible. Send a description of the material, specifying its size, format, and copyright status. Since the ACL is a not-for-profit organization, the costs of the tapes and the labor to prepare them might be tax-deductible. We will be exploring that possibility. The current members of the ACL/DCI Committee are Robert Amsler (Bellcore), Bran Boguraev (IBM T.J. Watson Research Center and Cambridge University), Ken Church (AT&T Bell Laboratories), Ed Fox (Virginia Polytechnic Institute & State University), Carole Hafner (Northeastern University), Judy Klavans (IBM T.J. Watson Research Center), Mark Liberman (AT&T Bell Laboratories), Mitch Marcus (University of Pennsylvania), Paul Martin (SRI International & MCC), Bob Mercer (IBM T.J. Watson Research Center), Jan Pedersen (Xerox PARC), Paul Roossin (IBM T.J. Watson Research Center), Don Walker (Bellcore), Susan Warwick (ISSCO), and Antonio Zampolli (University of Pisa). Liberman is chairing the committee. In a related development, Mitch Marcus at the University of Pennsylvania has a grant from the General Electric Corporate Research and Development Center and is receiving funding from the U.S. Defense Advanced Research Projects Agency and the U.S. Air Force Office of Scientific Research for the initial work on a "Tree Bank of Written and Spoken American English." His intent is to annotate millions of sentences with part of speech assignments, skeletal syntactic parsings, intonational boundaries for spoken language, and other forms of linguistic information that can be encoded consistently and quickly. At the same time, the project can be expected to develop a methodology for annotation that should be of general interest. This body of tagged and annotated materials is expected to derive at least in part from the ACL/DCI collection and to be available for distribution through it. The Tree Bank project will also be coordinated with the work of the TEI Committee on Text Analysis and Interpretation, which will be concentrating initially on developing tag sets for linguistically salient features of texts. It is also appropriate to note here that the National Endowment for the Humanities is considering the establishment of a "Center for Machine-Readable Texts in the Humanities." A planning grant to evaluate its feasibility has been awarded to Rutgers and Princeton. Further information will be provided as it becomes available. One final item: the ACL and Bellcore are arranging an open meeting to bring together publishers, software developers, and members of the research community to consider and hopefully resolve the conflicts of interest that impede the development of lexical resources. It will take place on 20 September 1989 in Oxford, England, the day after the 5th Annual Conference of the University of Waterloo Centre for the New Oxford English Dictionary, which this year will address the theme "Dictionaries in the Electronic Age." Further communications regarding the ACL/DCI should be directed to Liberman or Walker; those regarding the Oxford meeting to Walker alone: Mark Y.

Fr: Edward A. Fox Re: ACM electronic publishing In reply to IRList V6 #1 message II.A.6. from Ben Shneiderman regarding ACM and Hypertext, it is appropriate for me to make the following comments about ACM activities regarding Hypertext and related areas. 1) ACM remains committed to the area of electronic publishing. For those interested, there is a statement of the plans of ACM Press Database and Electronic Products in the Aug. 1988 CACM on page 948. There is also a list of points to be included in proposals. Everyone is encouraged to send their comments, ideas, offers of assistance, proposals for new products/services they would like to see or to work with ACM on producing, etc. 2) To extend the efforts in this area, I have made two appointments. One is Gary Marchionini, the editor in charge of the Hypertext area. The other is Scott Stevens, the editor in charge of the interactive multimedia area. They can be reached at the following addresses: Gary Marchionini 4121G Hornblake CLIS U. of Maryland College Park, MD 20742 (301) 454-3235 Internet address: MARCH@umdd.umd.edu Scott M. Stevens Software Engineering Institute Carnegie Mellon University Pittsburgh, PA 15213 (412) 268-7700 Internet address: sms@sei.cmu.edu 3) As far as specific products, to date there are only two. The first is "Hypertext on Hypertext" which is available from ACM for IBM PC-like systems, Macintosh, Sun, and Apollo. The second is a videotape which can now be ordered from ACM, which will be available very soon, entitled "Interactive Digital Video," and serves as a supplement to the July 1989 CACM with its special section on Interactive Technologies. 4) There will soon be a few more. One is a paper booklet on ADA taken from the ACM Guide to the Computing Literature and from Computing Reviews. The other will be some form of the Hypertext '89 Conference proceedings. At some point, there will be a version released to run under KMS for Sun and Apollo systems. There may be some "interchange form" -- ACM is supporting the effort of the National Institute of Standards and Technology in January to work toward Hypertext standards if and when they are appropriate. And other versions may be forthcoming too. 5) Next, to answer Ben's question. In order to encourage the use of Hypertext by the computing community, ACM prepared an RFP early this year, to determine the current situation, and to identify partners who might work with ACM in preparing Hypertext products. Various vendors responded. After a review process, Knowledge Workshop Incorporated was selected as the first vendor to work with ACM in this regard. Thus, they will be involved in the effort mentioned above to prepare a KMS version of the Hypertext '89 proceedings. ACM has not yet selected another vendor. We are encouraging development of Hypertext interchange methods, and are open to other suggestions regarding how Hypertext collections built with KMS can be delivered with other software and other platofrms, perhaps after some export and/or import processing, maybe going through some interchange "standard." My view is that "open systems" are very important in this area. We will proceed carefully in this arena. 6) Finally, to put this in a wider context, it is important to mention the issue of electronic submissions. Tentative plans have been made for a meeting in connection with the ACM Computer Science Conference in February in Washington, to discuss how ACM can develop a scheme to allow a large percentage of papers submitted to be received in an electronic form. One possibility is to agree upon a standard form that would be used by ACM for its internal electronic library -- perhaps the "Standard for Electronic Manuscript Preparation and Markup" developed by the Association of American Publishers, which has been formally approved by the American National Standards Institute as ANSI/NISO Z39.59-1988. This is fully compliant with the international standard SGML, ISO 8879-1986. More information about this can be obtained from EPSIG, c/o OCLC, 6565 Frantz Road, Dublin, OH 43017-0702 (614) 764-6195, FAX (614) 764-6096. Note that if such a standard is selected, then volunteer assistance would be required to develop "author kits" so that people can write papers in TeX, LaTeX, TROFF, etc. using a special set of macros so that 1-1 translation can be done into the standard. I invite interested parties to contact me, Bernard Rous (at ACM, 212/869-7440; BITNET: rous-cr@acmvm), or Gary or Scott (see information above).

Lewis) Re: Update on test collections Since January, when I sent the message on test collections that recently appeared on IRLIST, I have assembled a list of some of the IR test collections that contain natural language text. This is available from me as: Information Retrieval Laboratory (IRL) Memo 89-4, "Sources for IR Test Collections Containin Free-Text Descriptors". No one who was willing to be listed at all insisted on limited distribution, so I am no longer attempting to keep two lists. I am however, still quite interested in hearing of the existence of further collections that are available to be freely announced. I also encourage those who have developed collections to get in touch with "redistributors" such as Ed Fox (with the Virginia Disk series) and the Data Collection Initiative. I have also produced, for the machine learning archive at UC Irvine, a reformatted version (CACM-3204-ML1) of the CACM-3204 collection. This version is more convenient for certain kinds of IR and machine learning experiments, especially where exact replicability is a concern. (The collection is not appropriate for natural language parsing experiments, since the original word order is not preserved.) The main features are a record format that is easily readable by both humans and programs, explicit encoding of both stemmed and unstemmed versions of words, separation of stopwords and non-stopwords, and cleaning up of some anomalies in the assignment of Computing Reviews categories. Citation information from CACM-3204 is not currently included in CACM-3204-ML1. Information on CACM-3204-ML1 is available in IRL Memo 89-5, "A Description of the CACM-3204-ML1 Test Collection", a revised version of which will be available in a couple of weeks. David D.

Fr: Edward A. Fox Re: Documentary on DVI, CD-I, Videodisc available Interactive Digital Video is the title of a documentary now available from ACM headquarters. This video production, almost one hour in length, was assembled as a supplement to the July 1989 Communications of the ACM and its special section on Interactive Technologies. A number of the authors of papers in that issue supplied videotape demonstrations or were interviewed, and a great deal of additional material was collected from researchers and developers of innovative interactive applications. This program is tutorial in nature, aimed at around the college level, but has exciting footage of systems and prototypes that have not been publicly released. It should be of interest to those interested in the future of the TV, computer, and human computer interaction fields.

Beginning with introductory comments from leading experts and demonstrations of innovative systems developed at the MIT Media Lab, it explains videodisc technology and illustrates it with an explanation of Illuminated Manuscripts from the J. Paul Getty Museum. After briefly explaining how video as well as audio can be stored in digital form on a computer, and how TV-style special effects are prepared or can be shown in windows on computer monitors, it explains tradeoffs in space and quality of image compression. Two promising technologies that are in the early stages of commercialization, DVI (Digital Video Interactive) and CD-I (Compact-Disc Interactive), are explained and illustrated. Computer systems involved are demonstrated, and innovative interactive applications are presented, taking the viewer from Mayan ruins to Seattle's scenic outdoors to a training room for software engineers to an animated museum for children to a music/video "listening booth" to a home furnishings design room. Here you can understand the promise of the next generation of multimedia computers, and the new level of realism that will emerge in home entertainment! *************************************************************** IRLIST Digest is distributed from the University of California, Division of Library Automation, 300 Lakeside Drive, Oakland, CA. 94612-3550.
