Preamble
|
||||
|
||||
This license establishes the terms under which a given free software
|
||||
Package may be copied, modified, distributed, and/or redistributed.
|
||||
The intent is that the Copyright Holder maintains some artistic
|
||||
control over the development of that Package while still keeping the
|
||||
Package available as open source and free software.
|
||||
|
||||
You are always permitted to make arrangements wholly outside of this
|
||||
license directly with the Copyright Holder of a given Package. If the
|
||||
terms of this license do not permit the full use that you propose to
|
||||
make of the Package, you should contact the Copyright Holder and seek
|
||||
a different licensing arrangement.
|
||||
|
||||
Definitions
|
||||

||||
"Contributor" means any party that has contributed code or other
|
||||
material to the Package, in accordance with the Copyright Holder's
|
||||
procedures.
|
||||
|
||||
"You" and "your" means any person who would like to copy,
|
||||
distribute, or modify the Package.
|
||||
|
||||
"Package" means the collection of files distributed by the
|
||||
Copyright Holder, and derivatives of that collection and/or of
|
||||
those files. A given Package may consist of either the Standard
|
||||
Version, or a Modified Version.
|
||||
|
||||
"Distribute" means providing a copy of the Package or making it
|
||||
accessible to anyone else, or in the case of a company or
|
||||
organization, to others outside of your company or organization.
|
||||
|
||||
"Distributor Fee" means any fee that you charge for Distributing
|
||||
this Package or providing support for this Package to another
|
||||
party. It does not mean licensing fees.
|
||||
|
||||
"Standard Version" refers to the Package if it has not been
|
||||
modified, or has been modified only in ways explicitly requested
|
||||
by the Copyright Holder.
|
||||
|
||||
"Modified Version" means the Package, if it has been changed, and
|
||||
such changes were not explicitly requested by the Copyright
|
||||
Holder.
|
||||
|
||||
"Original License" means this Artistic License as Distributed with
|
||||
the Standard Version of the Package, in its current version or as
|
||||
it may be modified by The Perl Foundation in the future.
|
||||
|
||||
"Source" form means the source code, documentation source, and
|
||||
configuration files for the Package.
|
||||
|
||||
"Compiled" form means the compiled bytecode, object code, binary,
|
||||
or any other form resulting from mechanical transformation or
|
||||
translation of the Source form.
|
||||

|
||||
Permission for Use and Modification Without Distribution
|
||||
|
||||
(1) You are permitted to use the Standard Version and create and use
|
||||
Modified Versions for any purpose without restriction, provided that
|
||||
you do not Distribute the Modified Version.
|
||||
|
||||
|
||||
Permissions for Redistribution of the Standard Version
|
||||
|
||||
(2) You may Distribute verbatim copies of the Source form of the
|
||||
Standard Version of this Package in any medium without restriction,
|
||||
either gratis or for a Distributor Fee, provided that you duplicate
|
||||
all of the original copyright notices and associated disclaimers. At
|
||||
your discretion, such verbatim copies may or may not include a
|
||||
Compiled form of the Package.
|
||||
|
||||
(3) You may apply any bug fixes, portability changes, and other
|
||||
modifications made available from the Copyright Holder. The resulting
|
||||
Package will still be considered the Standard Version, and as such
|
||||
will be subject to the Original License.
|
||||
|
||||
|
||||
Distribution of Modified Versions of the Package as Source
|
||||
|
||||
(4) You may Distribute your Modified Version as Source (either gratis
|
||||
or for a Distributor Fee, and with or without a Compiled form of the
|
||||
Modified Version) provided that you clearly document how it differs
|
||||
from the Standard Version, including, but not limited to, documenting
|
||||
any non-standard features, executables, or modules, and provided that
|
||||
you do at least ONE of the following:
|
||||
|
||||
(a) make the Modified Version available to the Copyright Holder
|
||||
of the Standard Version, under the Original License, so that the
|
||||
Copyright Holder may include your modifications in the Standard
|
||||
Version.
|
||||
|
||||
(b) ensure that installation of your Modified Version does not
|
||||
prevent the user installing or running the Standard Version. In
|
||||
addition, the Modified Version must bear a name that is different
|
||||
from the name of the Standard Version.
|
||||
|
||||
(c) allow anyone who receives a copy of the Modified Version to
|
||||
make the Source form of the Modified Version available to others
|
||||
under
|
||||
|
||||
(i) the Original License or
|
||||
|
||||
(ii) a license that permits the licensee to freely copy,
|
||||
modify and redistribute the Modified Version using the same
|
||||
licensing terms that apply to the copy that the licensee
|
||||
received, and requires that the Source form of the Modified
|
||||
Version, and of any works derived from it, be made freely
|
||||
available in that license fees are prohibited but Distributor
|
||||
Fees are allowed.
|
||||
|
||||
|
||||
Distribution of Compiled Forms of the Standard Version
|
||||
or Modified Versions without the Source
|
||||
|
||||
(5) You may Distribute Compiled forms of the Standard Version without
|
||||
the Source, provided that you include complete instructions on how to
|
||||
get the Source of the Standard Version. Such instructions must be
|
||||
valid at the time of your distribution. If these instructions, at any
|
||||
time while you are carrying out such distribution, become invalid, you
|
||||
must provide new instructions on demand or cease further distribution.
|
||||
If you provide valid instructions or cease distribution within thirty
|
||||
days after you become aware that the instructions are invalid, then
|
||||
you do not forfeit any of your rights under this license.
|
||||
|
||||
(6) You may Distribute a Modified Version in Compiled form without
|
||||
the Source, provided that you comply with Section 4 with respect to
|
||||
the Source of the Modified Version.
|
||||
|
||||
|
||||
Aggregating or Linking the Package
|
||||
|
||||
(7) You may aggregate the Package (either the Standard Version or
|
||||
Modified Version) with other packages and Distribute the resulting
|
||||
aggregation provided that you do not charge a licensing fee for the
|
||||
Package. Distributor Fees are permitted, and licensing fees for other
|
||||
components in the aggregation are permitted. The terms of this license
|
||||
apply to the use and Distribution of the Standard or Modified Versions
|
||||
as included in the aggregation.
|
||||
|
||||
(8) You are permitted to link Modified and Standard Versions with
|
||||
other works, to embed the Package in a larger work of your own, or to
|
||||
build stand-alone binary or bytecode versions of applications that
|
||||
include the Package, and Distribute the result without restriction,
|
||||
provided the result does not expose a direct interface to the Package.
|
||||
|
||||
|
||||
Items That are Not Considered Part of a Modified Version
|
||||
|
||||
(9) Works (including, but not limited to, modules and scripts) that
|
||||
merely extend or make use of the Package, do not, by themselves, cause
|
||||
the Package to be a Modified Version. In addition, such works are not
|
||||
considered parts of the Package itself, and are not subject to the
|
||||
terms of this license.
|
||||
|
||||
|
||||
General Provisions
|
||||
|
||||
(10) Any use, modification, and distribution of the Standard or
|
||||
Modified Versions is governed by this Artistic License. By using,
|
||||
modifying or distributing the Package, you accept this license. Do not
|
||||
use, modify, or distribute the Package, if you do not accept this
|
||||
license.
|
||||
|
||||
(11) If your Modified Version has been derived from a Modified
|
||||
Version made by someone other than you, you are nevertheless required
|
||||
to ensure that your Modified Version complies with the requirements of
|
||||
this license.
|
||||
|
||||
(12) This license does not grant you the right to use any trademark,
|
||||
service mark, tradename, or logo of the Copyright Holder.
|
||||
|
||||
(13) This license includes the non-exclusive, worldwide,
|
||||
free-of-charge patent license to make, have made, use, offer to sell,
|
||||
sell, import and otherwise transfer the Package with respect to any
|
||||
patent claims licensable by the Copyright Holder that are necessarily
|
||||
infringed by the Package. If you institute patent litigation
|
||||
(including a cross-claim or counterclaim) against any party alleging
|
||||
that the Package constitutes direct or contributory patent
|
||||
infringement, then this Artistic License to you shall terminate on the
|
||||
date that such litigation is filed.

* ---------------------------------------------------------------------------
|
||||
* This tail recursive predicate solves the problem currently in memory with a
|
||||
* Monte Carlo approach.
|
||||
* It requires the number of samples and successes so far (Count and Success),
|
||||
* the desired list of Goals to fulfil, the number K of samples to consider at
|
||||
* once and the threshold MinError for the binomial proportion confidence
|
||||
* interval.
|
||||
* It returns the total number of Samples considered, the Lower and Upper ends
|
||||
* of the the binomial proportion confidence interval and the extimated Prob.
|
||||
*
|
||||
* INPUT
|
||||
* - Count: number of samples considered so far.
|
||||
* - Success: number of successfull samples considered so far.
|
||||
* - Goals: list of goals to fulfil.
|
||||
* - K: number of samples to consider at once.
|
||||
* - MinError: threshold for the binomial proportion confidence interval.
|
||||
*
|
||||
* OUTPUT
|
||||
* - Samples: total number of samples considered.
|
||||
* - Lower: lower end of the the binomial proportion confidence interval.
|
||||
* - Prob: extimated probability.
|
||||
* - Upper: upper end of the the binomial proportion confidence interval.
|
||||
*
|
||||
* NB: This method is based on the binomial proportion confidence interval and
|
||||
* the Brown's rule of thumb to avoid the case the sample proportion is
|
||||
* exactly 0.0 or 1.0 and doesn't make use of BDDs.

|
||||
Package available as open source and free software.
|
||||
|
||||
You are always permitted to make arrangements wholly outside of this
|
||||
license directly with the Copyright Holder of a given Package. If the
|
||||
terms of this license do not permit the full use that you propose to

"You" and "your" means any person who would like to copy,
|
||||
distribute, or modify the Package.
|
||||
|
||||
"Package" means the collection of files distributed by the
|
||||
Copyright Holder, and derivatives of that collection and/or of
|
||||
those files. A given Package may consist of either the Standard
|
||||
Version, or a Modified Version.
|
||||
|
||||
"Distribute" means providing a copy of the Package or making it
|
||||
accessible to anyone else, or in the case of a company or
|
||||
organization, to others outside of your company or organization.
|
||||
|
||||
"Distributor Fee" means any fee that you charge for Distributing
|
||||
this Package or providing support for this Package to another
|
||||
party. It does not mean licensing fees.
|
||||
|
||||
"Standard Version" refers to the Package if it has not been
|
||||
modified, or has been modified only in ways explicitly requested
|
||||
by the Copyright Holder.
|
||||
|
||||
"Modified Version" means the Package, if it has been changed, and
|
||||
such changes were not explicitly requested by the Copyright
|
||||
Holder.
|
||||
|
||||
"Original License" means this Artistic License as Distributed with
|
||||
the Standard Version of the Package, in its current version or as
|
||||
it may be modified by The Perl Foundation in the future.
|
||||
|
||||
"Source" form means the source code, documentation source, and
|
||||
configuration files for the Package.
|
||||
|
||||
"Compiled" form means the compiled bytecode, object code, binary,
|
||||
or any other form resulting from mechanical transformation or
|
||||
translation of the Source form.
|
||||
|
||||
|
||||
Permission for Use and Modification Without Distribution
|
||||
|
||||
(1) You are permitted to use the Standard Version and create and use
|
||||
Modified Versions for any purpose without restriction, provided that
|
||||
you do not Distribute the Modified Version.
|
||||
|
||||
|
||||
Permissions for Redistribution of the Standard Version
|
||||
|
||||
(2) You may Distribute verbatim copies of the Source form of the
|
||||
Standard Version of this Package in any medium without restriction,
|
||||
either gratis or for a Distributor Fee, provided that you duplicate
|
||||
all of the original copyright notices and associated disclaimers. At
|
||||
your discretion, such verbatim copies may or may not include a
|
||||
Compiled form of the Package.
|
||||
|
||||
(3) You may apply any bug fixes, portability changes, and other
|
||||
modifications made available from the Copyright Holder. The resulting
|
||||
Package will still be considered the Standard Version, and as such
|
||||
will be subject to the Original License.
|
||||
|
||||
|
||||
Distribution of Modified Versions of the Package as Source
|
||||
|
||||
(4) You may Distribute your Modified Version as Source (either gratis
|
||||
or for a Distributor Fee, and with or without a Compiled form of the
|
||||
Modified Version) provided that you clearly document how it differs
|
||||
from the Standard Version, including, but not limited to, documenting
|
||||
any non-standard features, executables, or modules, and provided that
|
||||
you do at least ONE of the following:
|
||||
|
||||
(a) make the Modified Version available to the Copyright Holder
|
||||
of the Standard Version, under the Original License, so that the
|
||||
Copyright Holder may include your modifications in the Standard
|
||||
Version.
|
||||
|
||||
(b) ensure that installation of your Modified Version does not
|
||||
prevent the user installing or running the Standard Version. In
|
||||
addition, the Modified Version must bear a name that is different
|
||||
from the name of the Standard Version.
|
||||
|
||||
(c) allow anyone who receives a copy of the Modified Version to
|
||||
make the Source form of the Modified Version available to others
|
||||
under
|
||||
|
||||
(i) the Original License or
|
||||
|
||||
(ii) a license that permits the licensee to freely copy,
|
||||
modify and redistribute the Modified Version using the same
|
||||
licensing terms that apply to the copy that the licensee
|
||||
received, and requires that the Source form of the Modified
|
||||
Version, and of any works derived from it, be made freely
|
||||
available in that license fees are prohibited but Distributor
|
||||
Fees are allowed.
|
||||
|
||||
|
||||
Distribution of Compiled Forms of the Standard Version
|
||||
or Modified Versions without the Source
|
||||
|
||||
(5) You may Distribute Compiled forms of the Standard Version without
|
||||
the Source, provided that you include complete instructions on how to
|
||||
get the Source of the Standard Version. Such instructions must be
|
||||
valid at the time of your distribution. If these instructions, at any
|
||||
time while you are carrying out such distribution, become invalid, you
|
||||
must provide new instructions on demand or cease further distribution.
|
||||
If you provide valid instructions or cease distribution within thirty
|
||||
days after you become aware that the instructions are invalid, then
|
||||
you do not forfeit any of your rights under this license.
|
||||
|
||||
(6) You may Distribute a Modified Version in Compiled form without
|
||||
the Source, provided that you comply with Section 4 with respect to
|
||||
the Source of the Modified Version.
|
||||
|
||||
|
||||
Aggregating or Linking the Package
|
||||
|
||||
(7) You may aggregate the Package (either the Standard Version or
|
||||
Modified Version) with other packages and Distribute the resulting
|
||||
aggregation provided that you do not charge a licensing fee for the
|

apply to the use and Distribution of the Standard or Modified Versions
|
||||
as included in the aggregation.
|
||||
|
||||
(8) You are permitted to link Modified and Standard Versions with
|
||||
other works, to embed the Package in a larger work of your own, or to
|
||||
build stand-alone binary or bytecode versions of applications that
|
||||
include the Package, and Distribute the result without restriction,

considered parts of the Package itself, and are not subject to the
|

modifying or distributing the Package, you accept this license. Do not
|

use, modify, or distribute the Package, if you do not accept this
|
||||
license.
|
||||
|
||||
(11) If your Modified Version has been derived from a Modified
|
||||
Version made by someone other than you, you are nevertheless required
|
||||
to ensure that your Modified Version complies with the requirements of
|
||||
this license.
|

||||
free-of-charge patent license to make, have made, use, offer to sell,
|
||||
sell, import and otherwise transfer the Package with respect to any
|
||||
patent claims licensable by the Copyright Holder that are necessarily
|
||||
infringed by the Package. If you institute patent litigation
|
||||
(including a cross-claim or counterclaim) against any party alleging
|
||||
that the Package constitutes direct or contributory patent
|
||||
infringement, then this Artistic License to you shall terminate on the
|

||||
sp1 and sp1npn (first fold of IMDB for target predicate sameperson)
|
||||
hmml2: hidden markov model
|

The Artistic License 2.0
|
||||
|
||||
Copyright (c) 2000-2006, The Perl Foundation.
|
||||
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
This license establishes the terms under which a given free software
|
||||
Package may be copied, modified, distributed, and/or redistributed.
|
||||
The intent is that the Copyright Holder maintains some artistic
|
||||
control over the development of that Package while still keeping the
|
||||
Package available as open source and free software.
|
||||
|
||||
You are always permitted to make arrangements wholly outside of this
|
||||
license directly with the Copyright Holder of a given Package. If the
|
||||
terms of this license do not permit the full use that you propose to
|
||||
make of the Package, you should contact the Copyright Holder and seek
|
||||
a different licensing arrangement.
|
||||
|
||||
Definitions
|
||||
|
||||
"Copyright Holder" means the individual(s) or organization(s)
|
||||
named in the copyright notice for the entire Package.
|
||||
|
||||
"Contributor" means any party that has contributed code or other
|
||||
material to the Package, in accordance with the Copyright Holder's
|
||||
procedures.
|
||||
|
||||
"You" and "your" means any person who would like to copy,
|
||||
distribute, or modify the Package.
|
||||
|
||||
"Package" means the collection of files distributed by the
|
||||
Copyright Holder, and derivatives of that collection and/or of
|
||||
those files. A given Package may consist of either the Standard
|
||||
Version, or a Modified Version.
|
||||
|
||||
"Distribute" means providing a copy of the Package or making it
|
||||
accessible to anyone else, or in the case of a company or
|
||||
organization, to others outside of your company or organization.
|
||||
|
||||
"Distributor Fee" means any fee that you charge for Distributing
|
||||
this Package or providing support for this Package to another
|
||||
party. It does not mean licensing fees.
|
||||
|
||||
"Standard Version" refers to the Package if it has not been
|
||||
modified, or has been modified only in ways explicitly requested
|
||||
by the Copyright Holder.
|
||||
|
||||
"Modified Version" means the Package, if it has been changed, and
|
||||
such changes were not explicitly requested by the Copyright
|
||||
Holder.
|
||||
|
||||
"Original License" means this Artistic License as Distributed with
|
||||
the Standard Version of the Package, in its current version or as
|
||||
it may be modified by The Perl Foundation in the future.
|
||||
|
||||
"Source" form means the source code, documentation source, and
|
||||
configuration files for the Package.
|
||||
|
||||
"Compiled" form means the compiled bytecode, object code, binary,
|
||||
or any other form resulting from mechanical transformation or
|
||||
translation of the Source form.
|
||||
|
||||
|
||||
Permission for Use and Modification Without Distribution
|
||||
|
||||
(1) You are permitted to use the Standard Version and create and use
|
||||
Modified Versions for any purpose without restriction, provided that
|
||||
you do not Distribute the Modified Version.
|
||||
|
||||
|
||||
Permissions for Redistribution of the Standard Version
|
||||
|
||||
(2) You may Distribute verbatim copies of the Source form of the
|
||||
Standard Version of this Package in any medium without restriction,
|
||||
either gratis or for a Distributor Fee, provided that you duplicate
|
||||
all of the original copyright notices and associated disclaimers. At
|
||||
your discretion, such verbatim copies may or may not include a
|
||||
Compiled form of the Package.
|
||||
|
||||
(3) You may apply any bug fixes, portability changes, and other
|
||||
modifications made available from the Copyright Holder. The resulting
|
||||
Package will still be considered the Standard Version, and as such
|
||||
will be subject to the Original License.
|
||||
|
||||
|
||||
Distribution of Modified Versions of the Package as Source
|
||||
|
||||
(4) You may Distribute your Modified Version as Source (either gratis
|
||||
or for a Distributor Fee, and with or without a Compiled form of the
|
||||
Modified Version) provided that you clearly document how it differs
|
||||
from the Standard Version, including, but not limited to, documenting
|
||||
any non-standard features, executables, or modules, and provided that
|
||||
you do at least ONE of the following:
|
||||
|
||||
(a) make the Modified Version available to the Copyright Holder
|
||||
of the Standard Version, under the Original License, so that the
|
||||
Copyright Holder may include your modifications in the Standard
|
||||
Version.
|
||||
|
||||
(b) ensure that installation of your Modified Version does not
|
||||
prevent the user installing or running the Standard Version. In
|
||||
addition, the Modified Version must bear a name that is different
|
||||
from the name of the Standard Version.
|
||||
|
||||
(c) allow anyone who receives a copy of the Modified Version to
|
||||
make the Source form of the Modified Version available to others
|
||||
under
|
||||
|
||||
(i) the Original License or
|
||||
|
||||
(ii) a license that permits the licensee to freely copy,
|
||||
modify and redistribute the Modified Version using the same
|
||||
licensing terms that apply to the copy that the licensee
|
||||
received, and requires that the Source form of the Modified
|
||||
Version, and of any works derived from it, be made freely
|
||||
available in that license fees are prohibited but Distributor
|
||||
Fees are allowed.
|
||||
|
||||
|
||||
Distribution of Compiled Forms of the Standard Version
|
||||
or Modified Versions without the Source
|
||||
|
||||
(5) You may Distribute Compiled forms of the Standard Version without
|
||||
the Source, provided that you include complete instructions on how to
|
||||
get the Source of the Standard Version. Such instructions must be
|
||||
valid at the time of your distribution. If these instructions, at any
|
||||
time while you are carrying out such distribution, become invalid, you
|
||||
must provide new instructions on demand or cease further distribution.
|
||||
If you provide valid instructions or cease distribution within thirty
|
||||
days after you become aware that the instructions are invalid, then
|
||||
you do not forfeit any of your rights under this license.
|
||||
|
||||
(6) You may Distribute a Modified Version in Compiled form without
|
||||
the Source, provided that you comply with Section 4 with respect to
|
||||
the Source of the Modified Version.
|
||||
|
||||
|
||||
Aggregating or Linking the Package
|
||||
|
||||
(7) You may aggregate the Package (either the Standard Version or
|
||||
Modified Version) with other packages and Distribute the resulting
|
||||
aggregation provided that you do not charge a licensing fee for the
|
||||
Package. Distributor Fees are permitted, and licensing fees for other
|
||||
components in the aggregation are permitted. The terms of this license
|
||||
apply to the use and Distribution of the Standard or Modified Versions
|
||||
as included in the aggregation.
|
||||
|
||||
(8) You are permitted to link Modified and Standard Versions with
|
||||
other works, to embed the Package in a larger work of your own, or to
|
||||
build stand-alone binary or bytecode versions of applications that
|
||||
include the Package, and Distribute the result without restriction,
|
||||
provided the result does not expose a direct interface to the Package.
|
||||
|
||||
|
||||
Items That are Not Considered Part of a Modified Version
|
||||
|
||||
(9) Works (including, but not limited to, modules and scripts) that
|
||||
merely extend or make use of the Package, do not, by themselves, cause
|
||||
the Package to be a Modified Version. In addition, such works are not
|
||||
considered parts of the Package itself, and are not subject to the
|
||||
terms of this license.
|
||||
|
||||
|
||||
General Provisions
|
||||
|
||||
(10) Any use, modification, and distribution of the Standard or
|
||||
Modified Versions is governed by this Artistic License. By using,
|
||||
modifying or distributing the Package, you accept this license. Do not
|
||||
use, modify, or distribute the Package, if you do not accept this
|
||||
license.
|
||||
|
||||
(11) If your Modified Version has been derived from a Modified
|
||||
Version made by someone other than you, you are nevertheless required
|
||||
to ensure that your Modified Version complies with the requirements of
|
||||
this license.
|
||||
|
||||
(12) This license does not grant you the right to use any trademark,
|
||||
service mark, tradename, or logo of the Copyright Holder.
|
||||
|
||||
(13) This license includes the non-exclusive, worldwide,
|
||||
free-of-charge patent license to make, have made, use, offer to sell,
|
||||
sell, import and otherwise transfer the Package with respect to any
|
||||
patent claims licensable by the Copyright Holder that are necessarily
|
||||
infringed by the Package. If you institute patent litigation
|
||||
(including a cross-claim or counterclaim) against any party alleging
|
||||
that the Package constitutes direct or contributory patent
|
||||
infringement, then this Artistic License to you shall terminate on the
|
||||
date that such litigation is filed.
|
||||
|
||||
(14) Disclaimer of Warranty:
|
||||
THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
|
||||
IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
|
||||
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
|
||||
NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
|
||||
LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
|
||||
BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
|
||||
DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
|
||||
ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

This folder cotains EMBLEM, an EM parameter learning algorithm, and SLIPCASE, a structure learning algorithm
|
||||
|
||||
To execute EMBLEM, load slicpase.pl with
|
||||
:- use_module(library('cplint/slipcase')).
|
||||
|
||||
and run
|
||||
|
||||
:- em(filestem).
|
||||
|
||||
in a directory containing filestem.kb, filestem.bg and filestem.l.
|
||||
You will find the output in filestem.rules.
|
||||
|
||||
To execute SLIPCASE, load slicpase.pl with
|
||||
:- use_module(library('cplint/slipcase')).
|
||||
|
||||
and run
|
||||
|
||||
:- sl(filestem).
|
||||
|
||||
in a directory containing filestem.kb, filestem.bg and filestem.l.
|
||||
You will find the output in filestem.rules.
