The Knowledge Engineering Review is planning a special issue on 
"Combined Symbolic & Numeric Processing Systems". Is there anyone 
out there with an interest in "theories and techniques for mixed 
symbolic/numeric processing systems" who is willing to write a
comprehensive review paper?
There follow the short notes for contributors. The first one is
in straight ascii, the second in postscript:

    THE KNOWLEDGE ENGINEERING REVIEW - SPECIAL ISSUE ON

   Inferences and Algorithms: co-operating in computation
                             or
     (Symbols and Numbers: co-operating in computation)



THEME

     The theme of this special issue of  KER  is  to  review
     developments  in the subject of integrated symbolic and
     numeric  computation.  The  subject  area  of  combined
     symbolic   and   numeric  computation  is  a  prominent
     emerging subject. In Europe, ESPRIT is already  funding
     a  $15m  project  to  investigate  the  integration  of
     symbolic and numeric computation  and  is  planning  to
     issue  a  further  call  for  a  $20m type A project in
     Autumn this year. In the USA, various funding agencies,
     like  the  DoD  and  NSF, have been heavily involved in
     supporting research into the  integration  of  symbolic
     and numeric computing systems over the last few years.

     Algorithmic  (or  numeric)  computational  methods  are
     mostly  used for low-level, data driven computations to
     achieve problem solutions by exhaustive evaluation, and
     are   based   on   static,  hardwired  decision  making
     procedures. The  statisticity  and  regularity  of  the
     knowledge,   data,  and  control  structures  that  are
     employed by  such  algorithmic  methods  permits  their
     efficient   mapping   and   execution  on  conventional
     supercomputers. However, the scale of  the  computation
     increases often non-linearly with the problem size, and
     the strength of the data inter-dependencies.


     Symbolic (or inference) computational methods have  the
     capability   to   drastically   reduce   the   required
     computations   by   using   high-level,    model-driven
     knowledge, and hypothesis-and-test techniques about the
     application   domain.    However,   the   irregularity,
     uncertainty, and dynamicity of the knowledge, data, and
     control  structures  that  are  employed  by   symbolic
     methods  presents  a  major obstacle to their efficient
     mapping  and   execution   on   conventional   parallel
     computers.

     This  has  led  many   researchers   to   propose   the
     development   of   integrated   numeric   and  symbolic
     computation  systems,  which  have  the  potential   to
     achieve   optimal   solutions   for  large  classes  of
     problems, in which algorithmic and  symbolic  component
     are  engaged  in  close co-operation. The need for such
     interaction   is   particularly   obvious    in    such
     applications    as    image    understanding,    speech
     recognition,     weather     forecasting,     financial
     forecasting,   the  solution  of  partial  differential
     equations etc.  In these applications, numeric software
     components  are  tightly  coupled  with  their symbolic
     counterparts, which in turn, have the  power  to  feed-
     back   adjustable   algorithm  parameters,  and  hence,
     support a "hypothesis-and-test" capability required  to
     validate the numeric data.

     It  is  this  application  domain  that  provided   the
     motivation   for   developing  theoretical  frameworks,
     techniques,   programming   languages,   and   computer
     architectures  to efficiently support both symbolic and
     numeric  computation.   The  special   issue   of   The
     Knowledge  Engineering  Review  KER  aims  to provide a
     comprehensive and timely review of the state of the art
     in    integrated   symbolic   and   numeric   knowledge
     engineering systems. The special issue will  cover  the
     topics outlined in the next section.

TOPICS
     There are four important topics that are related to the
     subject   area   of  integrated  symbolic  and  numeric
     computation.  This  special   issue   will   have   one
     comprehensive review paper in each of the topics, and a
     general overview article (or editorial)  to  link  them
     together.

      1. Theory and Techniques
         Traditional  theoretical  frameworks  for  decision
         making  are  are  generally  considered  to  be too
         restrictive  for  developing  practical   knowledge
         based systems. The principal set of restrictions is
         that classical algorithmic  decision  theories  and
         techniques  do not address the need to reason about
         the decision process itself.  Classical  techniques
         cannot  reflect  on  what the decision is, what the
         options are, what methods should be (or have  been)
         used  in  making  decision and so forth. Approaches
         that accommodate numerical methods but extend  them
         with   non-monotonic   inference   techniques   are
         described  extensively  in   the   literature   e.g
         [Coguen, Eberbach, Vanneschi, Fox et al, etc]. What
         is needed is an  in-depth  analysis,  taxonomy  and
         evaluation  of these techniques. This review of the
         theoretical   approaches   and   background    into
         integrated  symbolic and numeric computation should
         be highly valuable to those involved  in  symbolic,
         numeric,   and  integrated  symbolic  plus  numeric
         computation.

      2. Applications
         Here there would be a review  of  the  applications
         which   provide   the   stimulus,  and  demonstrate
         techniques for  integrating  symbolic  and  numeric
         computing  components. Effectiveness considerations
         and performance gains should also be included where
         appropriate.  Model applications may include: image
         understanding,   weather   forecasting,   financial
         forecasting,   expert   systems  for  PDE  solving,
         simulation,  real-time  process  control,etc.   The
         review article should expose the common ground that
         these applications share, the potential improvement
         in   reasoning   and  computation  efficiency,  the
         requirements that they impose  on  the  theoretical
         frameworks,  programming  languages,  and  computer
         architecture.

      3. Programming Languages
         This would be a review of the programming languages
         which  provide  the  means for integrating symbolic
         and numeric  computations.  The  article(s)  should
         describe the competing approaches, i.e. integration
         through  homogenisation,  and  integration  through
         interfacing  heterogeneous systems. Language design
         issues, features  for  parallelism,  etc.  Possible
         languages  that  might  be considered are: Spinlog,
         Orient84K, LOOPS , Cornerstone, Solve, Parle,  etc.
         A  comparative  analysis  of the involved languages
         should be included.

      4. Computer Architecture
         This review should give a comprehensive  review  of
         the novel computer architectures that are involved,
         their basic operating  principles,  their  internal
         structure,  a  comparative  analysis, etc. Possible
         architectures  that  might   be   considered   are:
         PADMAVATI, SPRINT, ...
