QUERIES II.B.1. Fr: Hung-Hsien Chang Re: Database of journals and symposiums Hi! I would like to know if there is any ftp site or sources of database which contains titles and authors of papers poublished in JACM, JCSS, information and computation, TCS, SIAM computing, ICALP, STACS , and STOCS. Or any other journals related to computer science and math. I think the publishers or organizations such as ACM , IEEE, or Academic press has their own database but I wonder if they have anonymous ftp access open to the public. Any information is welcomed. Please send mail directly to hubert@cs.ucsb.edu; I will post the collected information afterwards. Thank you.

Litvinchouk Re: Hypertext-tools for Sun Sparc 4/330 Several people have emailed me for more information about the "HyperCMedia" toolkit for Sun-4. Here is all the information I have on it so far: According to the brochure, hyperCmedia is a hypertext/hypermedia toolkit that provides a functional subroutine library callable from C. The toolkit is implemented as a shared library. According to the vendor (Paradise Software), hyperCmedia assumes that the calling application knows how to do windowing; they believe that hyperCmedia should be callable from other languages as well. Hypertext links and tools for browsing the resulting graph are supported. hyperCmedia supports runtime document construction and formatting to facilitate the display of real-time information. A document page can contain control buttons and scrollbars. Text with multiple fonts and styles, raster graphics, audio, and video can be combined on a document page. Library routines support access of information from laserdisc. The only problem (for us it's a big problem) is that hyperCmedia doesn't currently work with 24-bit color graphics, only with 8-bit color. hyperCmedia is available for SunView and OpenWindows; a Motif version will be shipping 1Q 1991. Price for both versions is $425 each. A runtime license is $25. The vendor of hyperCmedia is: Paradise Software, Inc. RD 1 Box 467A Lambertville, New Jersey 08530 609-397-4142 support@psi.paradise.com They also make a related product, "VideoPhile", for capturing and playing full-motion video on Sparcstations. Developer's price: $1995; runtime license: $200. If you send them a blank 1/4" cartridge tape, they'll send it back to you with demo versions of hyperCmedia and videoPhile. - -- Steven Litvintchouk MITRE Corporation Burlington Road Bedford, MA 01730 (617)271-7753 ARPA: sdl@mbunix.mitre.org UUCP: ...{att,decvax,genrad,necntc,ll-xn,philabs,utzoo}!linus!sdl "Where does he get those wonderful toys?" ********** II.B.3. Fr: Wiliam M. Gilroy Re: More on HyperCMedia Hello netters, I requested and received the demo tape. It contains some pretty interesting demos. In the most memorable, "newspeak," Paradise Software has put together a hypermedia demonstration in which the San Francisco earthquake is described using text, images, sound, and video. The demo it manifests itself as a newspaper including headline, some still images, and a number of stories describing the quake. The most incredible part of the demo is that the still images, when moused, become full motion color video (sound track included). What's amazing is that I don't have video hardware in my machine. This is the result of their videophile package that allows you to capture full motion video, store it in a file, and play it back with no video hardware. Another interesting point is that the application was invoked across an NFS link with no degredation of the video performance. This is actually some pretty neat stuff. Anyway, I just thought I'd chime in with an observation about a pretty neat demo. Best Regards, William M. Gilroy wmg@pixels.att.com ********************************************************** IV.

TI AN EMPIRICAL INVESTIGATION OF THE EFFECTS OF PERSONALITY TYPE AND VARIATION IN INFORMATION LOAD ON THE INFORMATION SEARCH STRATEGIES EMPLOYED BY DECISION-MAKERS. IN Texas A&M University Ph.D. 1990, 256 pages. DE Business Administration, Accounting. Psychology, Personality. Information Science. AB The objectives of the study were to: (1) investigate the ways in which decision makers adapt their information search strategies in response to increases in the supply of information; and (2) assess whether the personality type of the decision maker affects the type of information search strategies employed to process the information. Explicit information search techniques were used in a laboratory experiment to examine the information-acquisition behavior of decision makers at various levels of task complexity. This technique traces the underlying cognitive process leading up to the final decision by monitoring what information was selected, the order that the information was selected, and the duration that each item of information was examined. The present study found that the type of information search strategies employed by decision makers was dependent on: (1) the amount of information available to the decision maker (task complexity); (2) the personality type of the decision maker; and (3) the interaction between the task complexity factors and the personality type of the decision maker. When the processing demands of the decision task were increased by adding to the number of alternatives to be evaluated, or by adding to the number of dimensions used to define each alternative, decision makers responded by eliminating some alternatives from further consideration on the basis of a very limited search of the information, and by spending more time processing each item of information. Furthermore, the type of information search strategies employed by decision makers, and the time spent processing the information was conditional on the subjects' personality preferences measured in accordance with Jungian constructs. The type of information search strategies that decision makers employed was dependent on: (1) the individuals' preferred (and most developed) mental function that provides overall direction and a consistent focus to their personality; and (2) the individuals' preferred way of perceiving the problem or situation with which they were faced. The study also compared the decision-making behavior of students from the laboratory experiment with the decision-making behavior of "real-world" managers, and reported that students were reasonable surrogates for managers.

IN The University of Florida Ph.D. 1989, 175 pages. DE Computer Science. Engineering, Electronics and Electrical. AB Maintaining the closure property is an important database language design objective. Queries issued in a query language that possesses this property return results that are structured and modeled by the same data model for which the query language is designed. A useful consequence of this is that the result of a query can be uniformly operated on by other queries (i.e., using the same language constructs). None of the existing query languages that have been designed for the class of object-oriented data models possesses the closure property. In this dissertation, we introduce a new query model for object-oriented databases in which this property is preserved. Furthermore, we make our query model concrete by introducing an object-oriented query language named OQL as an example of this query model. A query in this language returns a subdatabase whose structure consists of some selected object classes and their associations. The objects that fall in the patterns of object associations specified in the query constitute the extension of the resulting subdatabase. In this dissertation, we also introduce a knowledge definition language for defining deductive rules and integrity constraints pertaining to an object-oriented database. Deductive rules in this language derive new patterns of associations among objects based on existing and/or other derived patterns. Deductive reasoning about a large number of objects stored in a database is a needed functionality in several new database application domains (e.g., CAD/CAM databases). The OQL and the knowledge definition language are tightly coupled. This facilitates the integration of concepts and techniques, which are typically found in different categories of systems such as database management systems and expert systems, into one integrated, object-oriented knowledge base management system (OKBMS) that meets the specifications and requirements of the new database application domains.

IN Cornell University Ph.D. 1990, 190 pages. DE Computer Science. AB The effective use of information retrieval systems by end-users has been limited by their lack of knowledge on the particular organization of the databases searched and by their limited experience on how to formulate and modify search statements. This thesis explores and evaluates two mechanisms to improve retrieval performance by end-users. The first mechanism complements the formulation of a query by allowing users to interactively add term phrases. These phrases are generated either from the query text or from known relevant documents. This addition of term phrases to a query is suggested by the term discrimination model as a precision enhancement device. An interactive front-end for the SMART information retrieval system was developed to perform the interactive experiments needed to evaluate different phrase addition strategies. The second aspect of retrieval improvement studied is the evaluation of two database organizations that can be used to obtain new relevant documents by looking in the neighborhood of known relevant documents, browsing. Browsing in cluster hierarchies and nearest-neighbor networks is compared to relevance feedback in non-interactive experiments. The results obtained for the phrase addition methodology showed that simple non-interactive addition of phrases can perform as well as interactive addition. Even an optimal selection of the phrases based on the relevant documents not yet retrieved, did not significantly improve performance over simply adding all the phrases generated. Many useful phrases are not selected by users because they look like random association of terms. The usefulness of these phrases comes from the fact that either they are pieces of larger (semantically meaningful) phrases, or they are made up of local synonyms specific to the document collection used. The browsing experiments in cluster hierarchies and nearest-neighbor networks showed that the second organization consistently performs better than relevance feedback in different collections. Cluster browsing is more dependent on the characteristics of the collections; but when the circumstances are favorable, cluster browsing can produce larger improvements on retrieval than network browsing. Retrieval in both structures is much faster than relevance feedback since only a small portion of the database needs to be inspected. AN University Microfilms Order Number ADGDX-89881.

AB Available from UMI in association with The British Library. This thesis first reviews existing methodologies highlighting their relative merits and weaknesses. This work provided the basis for the specification of a low-cost FILTER* based retrieval system which employs an APP (Associative Parallel Processor) for efficient character string matching. The resultant retrieval model features three concurrent processes which scans document text to eliminate intermediate indexes, and searches on-the-fly to minimise retrieval times. Hence this approach makes possible: (1) flexible access capabilities, (2) reduction in file storage (hardware) and maintenance (software) overheads, (3) simplified data base organization, permitting fast update. The experimental investigation was conducted in two phases. In Phase 1, the internal architecture and the retrieval algorithms for the FILTER were tested by simulation. The results obtained indicate that the design is fundamentally viable, and capable of operating at a wide range of disk transfer speeds. Phase 2 tested the conceptual operation of the "FILTER retrieval model" by implementation. The model is implementation independent, and in the absence of usable APP hardware, a commercially available associative processor called REM (REcognition Memory), was used to aid the implementation. This confirmed that the model is both functionally and economically realizable. These experiments indicated that special hardware can be minimized by suitable partitioning of the FILTER based retrieval model, while retrieving at speeds in the range 0.23-0.95 Mbytes/Second (worst case). This is comparable to substantially more costly systems currently under development. Hence, it is concluded that a low-cost microcomputer based document retrieval system is well within the scope of the requirements for the personal applications environment.
