Free provided synonym software for linux

Xapian is an Open Source Probabilistic Information Retrieval library, released under the GPL. Xapian iss written in C++, with bindings to allow use from other languages (Perl, Java, Python, PHP, and TCL are currently supported; Guile and C# are being worked on).
Xapian is designed to be a highly adaptable toolkit to allow developers to easily add advanced indexing and search facilities to their own applications.
If youre after a packaged search engine for your website, you should take a look at Omega, which is an application we supply built upon Xapian. But unlike most other website search solutions, Xapians versatility allows you to extend Omega to meet your needs as they grow.
Main features:
- Free Software/Open Source - licensed under the GPL.
- Highly portable - runs on many Linux, MacOS X, many other Unix platforms, and Microsoft Windows.
- Written in C++. Perl bindings are available in the module Search::Xapian on CPAN. Java JNI bindings are included in the xapian-bindings module. We also support SWIG which can generate bindings for 13 languages. At present those for Python, PHP4, and TCL are working. Guile and C# are being worked on.
- Ranked probablistic search - important words get more weight than unimportant words, so the most relevant documents are more likely to come near the top of the results list.
- Relevance feedback - given one or more documents, Xapian can suggest the most relevant index terms to expand a query, suggest related documents, categorise documents, etc.
- Phrase and proximity searching - users can search for words occuring in an exact phrase or within a specified number of words, either in a specified order, or in any order.
- Full range of structured boolean search operators ("stock NOT market", etc). The results of the boolean search are ranked by the probablistic weights. Boolean filters can also be applied to restrict a probabilistic search.
- Supports stemming of search terms (e.g. a search for "football" would match documents which mention "footballs" or "footballer"). This helps to find relevant documents which might otherwise be missed. Stemmers are currently included for Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish.
- Supports database files > 2GB - essential for scaling to large document collections.
- Platform independent data formats - you can build a database on one machine and search it on another.
- Allows simultaneous update and searching. New documents become searchable right away.
As well as the library, we supply a number of small example programs, and a larger application - an indexing and CGI-based application called omega:
- The indexer supplied can index HTML, PHP, PDF, PostScript, and plain text. Adding support for indexing other formats is easy where conversion filters are available (e.g. Microsoft Word). This indexer works using the filing system, but we also provide a script to allow the htdig web crawler to be hooked in, allowing remote sites to be searched using Omega.
- You can also index data from any SQL or other RDBMS supported by the Perl DBI module. That includes MySQL, PostgreSQL, SQLite, Sybase, MS SQL, LDAP, and ODBC.
- CGI search front-end supplied with highly customisable appearance. This can also be customised to output results in XML or CSV, which is useful if you are dynamically generating pages (e.g. with PHP or mod_perl) and just want raw search results which you can process in your own page layout code.
Enhancements:
- This release adds support for spelling correction and synonym expansion.
- Some Btree tables are now optional, so opening a database is slightly quicker.
- The Xapian::NumberValueRangeProcessor class has been reworked to fix a design flaw.
- A few bugs have been fixed.
- Performance was improved in several cases.

File::BSDGlob is a Perl extension for BSD glob routine.

SYNOPSIS

use File::BSDGlob :glob;
@list = glob(*.[ch]);
$homedir = glob(~gnat, GLOB_TILDE | GLOB_ERR);
if (GLOB_ERROR) {
# an error occurred reading $homedir
}

## override the core glob (even with -T)
use File::BSDGlob globally;
my @sources =

File::BSDGlob implements the FreeBSD glob(3) routine, which is a superset of the POSIX glob() (described in IEEE Std 1003.2 "POSIX.2"). The glob() routine takes a mandatory pattern argument, and an optional flags argument, and returns a list of filenames matching the pattern, with interpretation of the pattern modified by the flags variable. The POSIX defined flags are:

GLOB_ERR

Force glob() to return an error when it encounters a directory it cannot open or read. Ordinarily glob() continues to find matches.

GLOB_MARK

Each pathname that is a directory that matches the pattern has a slash appended.

GLOB_NOCHECK

If the pattern does not match any pathname, then glob() returns a list consisting of only the pattern. If GLOB_QUOTE is set, its effect is present in the pattern returned.

GLOB_NOSORT

By default, the pathnames are sorted in ascending ASCII order; this flag prevents that sorting (speeding up glob()).
The FreeBSD extensions to the POSIX standard are the following flags:

GLOB_BRACE

Pre-process the string to expand {pat,pat,...} strings like csh(1). The pattern {} is left unexpanded for historical reasons (and csh(1) does the same thing to ease typing of find(1) patterns).

GLOB_NOMAGIC

Same as GLOB_NOCHECK but it only returns the pattern if it does not contain any of the special characters "*", "?" or "[". NOMAGIC is provided to simplify implementing the historic csh(1) globbing behaviour and should probably not be used anywhere else.

GLOB_QUOTE

Use the backslash () character for quoting: every occurrence of a backslash followed by a character in the pattern is replaced by that character, avoiding any special interpretation of the character.

GLOB_TILDE

Expand patterns that start with ~ to user name home directories.

GLOB_CSH

For convenience, GLOB_CSH is a synonym for GLOB_BRACE | GLOB_NOMAGIC | GLOB_QUOTE | GLOB_TILDE.

The POSIX provided GLOB_APPEND, GLOB_DOOFFS, and the FreeBSD extensions GLOB_ALTDIRFUNC, and GLOB_MAGCHAR flags have not been implemented in the Perl version because they involve more complex interaction with the underlying C structures.

PFScalibration project provides an implementation of the Robertson et al. 2003 method for the photometric calibration of cameras and for the recovery of high dynamic range (HDR) images from the set of low dynamic range (LDR) exposures.

Tools provided with this software can be used for photometric calibration of both off-the-shelf digital cameras and HDR cameras as described in the MPI Research Report. A short tutorial on calibration of the LDR cameras and the recovery of the HDR images from multiple exposures is provided below. For details on the calibration of the HDR cameras please refer to the research report.

Geo::Ellipsoids is a package for standard Geo:: ellipsoid a, b, f and 1/f values.

SYNOPSIS

use Geo::Ellipsoids;
my $obj = Geo::Ellipsoids->new();
$obj->set(WGS84); #default
print "a=", $obj->a, "n";
print "b=", $obj->b, "n";
print "f=", $obj->f, "n";
print "i=", $obj->i, "n";
print "e=", $obj->e, "n";
print "n=", $obj->n(45), "n";

CONSTRUCTOR

new

The new() constructor may be called with any parameter that is appropriate to the set method.

my $obj = Geo::Ellipsoid->new();

METHODS

set

Method sets the current ellipsoid. This method is called when the object is constructed (default is WGS84).

$obj->set(); #default WGS84
$obj->set(Clarke 1866); #All built in ellipsoids are stored in meters
$obj->set({a=>1, b=>1}); #Custom Sphere 1 unit radius
list

Method returns a list of known elipsoid names.

my @list=$obj->list;

my $list=$obj->list;
while (@$list) {
print "$_n";
}
a

Method returns the value of the semi-major axis.

my $a=$obj->a;
b

Method returns the value of the semi-minor axis.

my $b=$obj->b; #b=a(1-f)
f

Method returns the value of flatting

my $f=$obj->f; #f=(a-b)/a
i

Method returns the value of the inverse flatting

my $i=$obj->i; #i=1/f=a/(a-b)
invf

Method synonym for the i method

my $i=$obj->invf; #i=1/f
e

Method returns the value of the first eccentricity, e. This is the eccentricity of the earths elliptical cross-section.

my $e=$obj->e;
e2

Method returns the value of eccentricity squared (e.g. e^2). This is not the second eccentricity, e or e-prime see the "ep" method.

my $e=sqrt($obj->e2); #e^2 = f(2-f) = 2f-f^2 = 1-b^2/a^2
ep

Method returns the value of the second eccentricity, e or e-prime. The second eccentricity is related to the first eccentricity by the equation: 1=(1-e^2)(1+e^2).

my $ep=$obj->ep;
ep2

Method returns the square of value of second eccentricity, e (e-prime). This is more useful in almost all equations.

my $ep=sqrt($obj->ep2); #ep2=(ea/b)^2=e2/(1-e2)=a^2/b^2-1
n

Method returns the value of n given latitude (degrees). Typically represented by the Greek letter nu, this is the radius of curvature of the ellipsoid perpendicular to the meridian plane. It is also the distance from the point in question to the polar axis, measured perpendicular to the ellipsoids surface.

my $n=$obj->n($lat);

Note: Some define a variable n as (a-b)/(a+b) this is not that variable.

n_rad

Method returns the value of n given latitude (radians).

my $n=$obj->n_rad($lat);
rho

rho is the radius of curvature of the earth in the meridian plane.

my $rho=$obj->rho($lat);
rho_rad

rho is the radius of curvature of the earth in the meridian plane.

my $rho=$obj->rho_rad($lat);
polar_circumference

Method returns the value of the semi-minor axis times 2*PI.

my $polar_circumference=$obj->polar_circumference;
equatorial_circumference

Method returns the value of the semi-major axis times 2*PI.

my $equatorial_circumference=$obj->equatorial_circumference;
shortname

Method returns the shortname, which is the hash key, of the current ellipsoid

my $shortname=$obj->shortname;
longname

Method returns the long name of the current ellipsoid

my $longname=$obj->longname;
data

Method returns a hash reference for the ellipsoid definition data structure.

my $datastructure=$obj->data;
name2ref

Method returns a hash reference (e.g. {a=>6378137,i=>298.257223563}) when passed a valid ellipsoid name (e.g. WGS84).

my $ref=$obj->name2ref(WGS84)
