Saklad) Subject: posting To which address do you submit postings, they don't seem to get through. [Note: I have changed the addresses at the top of each digest, to what I hope is a very reliable list. Our ARPANET connection is working but changes to our software and mail handling routines still have to be completed before they will be usable, so I have listed an address that goes through csnet-relay. Seismo and vtisr1 will not be usable by us beginning in a few days, so I have removed mention of them. I hope to begin sending IRList out using BITNET list handling support, so there may be some problems in the next few weeks as I change addresses etc. Please let me know if you have any specific difficulties or do not receive mail for a long period. - Ed] ------------------------------ Date: Mon, 10 Aug 87 15:49:34 EDT From: seismo!UDEL.EDU!Brady Subject: query for IRList What are good data compression packages that run on the IBM PC family? I will summarize replies and send back to the net. ////// joe brady ------------------------------ Date: 11 Aug 87 05:57 EDT From: science@nems.ARPA (Mark Zimmermann) Subject: RE: help re David Sherman's query I am working on developing software to let users index and then browse completely free, unstructured text files of arbitrary size. As mentioned on IRList some months ago, a version of this is now available on the Macintosh, "Browser v.244+" (just send me s.a.s.e. and Mac disk; foreigners need only send a note with their address). I now have preliminary versions of indexing/browsing programs now in C, which seem to work on VAX and Sun systems as well as on the Mac. Indexing rate is > 2 MB/hour typically; temporary disk space of 5-6 times the size of the input text is required, but when the index is sorted and squeezed the final space requirement is only about 80% of the text size. The browser lets a user scan through a complete inverted index to every word in the original document, showing number of occurrences ... when a good word is found in the index, a keystroke jumps into a key-word-in-context display of the occurrences of that word, and from there a keystroke gets you into the original text ... program currently includes facilities for taking notes in a separate file, for spooling copies of retrieved text into the notes file, etc. I plan to add proximity searching soon. The index structure is exceedingly simple and should make it possible to add other tools for correlating, clustering, etc. If interested, let me know and I will send copies of source code in C ... programs are heavily commented and occupy 20-30 kB each. I am not very good at sending msgs across net boundaries, so if you don't receive a reply from me, keep trying. ^z (Mark Zimmermann, science@nems.arpa, 9511 Gwyndale Dr., Silver Spring, MD 20910; tel. 301-565-2166) ------------------------------ Date: Tue, 11 Aug 87 12:41 PDT From: IIN4CLB@UCLAMVS Subject: wrong UCLA zip code Ed, as Jeff suttor just pointed out to me, I gave the wrong zip code for UCLA: 90034 when it should be 90024 ... Thanks for putting in a brief correction. [Note: this refers to IRlist V3 #25 msg - Ed] thanks! Chris ------------------------------ Date: Mon, 10 Aug 87 10:19:48 edt From: "Robert B.

This posting is also for the benefit of those who missed the first announcement or who are new to the AIList. We are now able to satisfy European and other foreign requests, so even if you are not a U.S.-based researcher or company, you may now have the sources. I will be giving an invited talk on the ISI Grapher in Symboliikka '87, Helsinki, Finland, August 17, 1987. The paper describing this effort is now available (for free) to all: it is entitled: "The ISI Grapher: a Portable Tool for Displaying Graphs Pictorially." The CommonLisp sources are also available (for free to all entities who receive DARPA funds, and for a small fee to all others). It currently runs on Symbolics versions 6, 7, and 7.1, and on TI Explorers versions 2 & 3. Efforts are currently underway to port it to other machines. If you would like the paper and/or the sources, please forward your postal address to "gabriel@vaxa.isi.edu" or to: Gabriel Robins Intelligent Systems Division Information Sciences Institute 4676 Admiralty Way Marina Del Rey, Ca 90292-6695 U.S.A. ============================================================================ The ISI Grapher August, 1987 Gabriel Robins Intelligent Systems Division Information Sciences Institute The ISI Grapher is a set of functions that convert an arbitrary graph structure (or relation) into an equivalent pictorial representation and displays the resulting diagram. Nodes and edges in the graph become boxes and lines on the workstation screen, and the user may then interact with the Grapher in various ways via the mouse and the keyboard. The fundamental motivation which gave birth to the ISI Grapher is the observation that graphs are very basic and common structures, and the belief that the ability to quickly display, manipulate, and browse through graphs may greatly enhance the productivity of a researcher, both quantitatively and qualitatively. This seems especially true in knowledge representation and natural language research. The ISI Grapher is both powerful and versatile, allowing an application-builder to easily build other tools on top of it. The ISI NIKL Browser is an example of one such tool. The salient features of the ISI Grapher are its portability, speed, versatility, and extensibility. Several additional applications were already built on top of the ISI Grapher, providing the ability to graph lists, flavors, packages, divisors, functions, and Common-Loops classes. Several basic Grapher operations may be user-controlled via the specification of alternate functions for performing these tasks. These operations include the drawing of nodes and edges, the selection of fonts, the determination of print-names, pretty-printing, and highlighting operations. Standard definitions are already provided for these operations and are used by default if the application-builder does not override them by specifying his own custom-tailored functions for performing the same tasks. The ISI Grapher now spans about 100 pages of CommonLisp code. The 120-page ISI Grapher manual is available; this manual describes the general ideas, the interface, the application-builder's back-end, the algorithms, the implementation, and the data structures. A shorter paper is also available, and includes hardcopy samples of the screen during execution. The ISI Grapher presently runs on both Symbolics (versions 6, 7, & 7.1) and TI Explorer workstations (versions 2 & 3); ports to other machines are underway. If you are interested in more information, the sources themselves, or just the paper/manual, please feel free to forward your postal address to "gabriel@vaxa.isi.edu" or write to "Gabriel Robins, Information Sciences Institute, 4676 Admiralty Way, Marina Del Rey, Ca 90292-6695 U.S.A." ------------------------------ Date: Tue, 11 Aug 87 23:17:22 edt From: Don Walker Subject: ACL 1988 Annual Conference CALL FOR PAPERS CALL FOR PAPERS 26th Annual Meeting of the Association for Computational Linguistics 7-10 June 1988 State University of New York at Buffalo Buffalo, New York TOPICS OF INTEREST: Papers are invited on substantial, original, and unpublished research on all aspects of computational linguistics, including, but not limited to, pragmatics, discourse, semantics, syntax, and the lexicon; phonetics, phonology, and morphology; interpreting and generating spoken and written language; linguistic, mathematical, and psychological models of language; machine translation and translation aids; natural language interfaces; message understanding systems; and theoretical and applications papers of every kind.
