Re: The progress of UF (was Future directions for ontologies and terminologies)

Hello,
According to the idiosyncratic psychiaterJaques Lacan there is the Symbolic (language etc.), the Imaginary (mirror, mirror on the wall who is...) and there is the Real. The Real is not expressible in language, nor can we approach it with the imaginary. I just mention Lacan because he brought this kind of  inexpressible into the field of psychoanalysis.
Our culture has the habit to fill the universe with words. But can that be? The old greeks had their gods - and they were very irrational. Their ontology was such that the gods, partly irrational, partly beyond grasp, had a part in it. For example with Socrates: Diotima.
In mathematics there are counter-intuitive truths. There are holes in the axiomatic way of grasping the mathematical universe. I think that current christian thinking can't work with what Gödel wrote because for the christian kind of thinking everything can be put into words. To my opinion  the essence of the conflict of science with the design theory of the universe is that not everything can be put into words. There is another world out there which can only partly  be understood by mathematics and for sure not by words.
Any ontology which does not give a place to the inexpressible is to my opinion a misfit. For religious people the inexpressible is clear: that is their god. But for me certainly not, although I believe there is the inexpressible. So, it is in the ontology that the clash with religious people comes to surface. That clash is clear: mathematical ideas have no meaning, no goal. And they want a goal.
There are of course many ideas which claim to be an ontology. But they talk only about things, concepts as they are (also thing-like) etc. and how to get them in a nice scheme. They are "ontic".
Very useful, but the ontic has not so much to do with ontology.
Ontology is about what comes first. Part of this firstness can not be grasped in words, images. What does a baby experience when someone tells: "o, it is laughing!"? The baby has no idea about laughing, no word for it. Maybe it starts learning what laughing is at that moment . Out of paradise! It is an example of a turning point where something inconceivable happens. A human is born.
I disagree that the religious and the scientific community have to talk about ontology and to come to a unified view. The clash is already within the scientific community about the inexpressible. Because many in the scientific community believe that all can be tackled by its hard and tedious working. But is that so?

My question for the future directions is about the inexpressible. Does it get a place?
with friendly greetings,
P tèr

Re: help

Sakshi,

If you would like to turn text into an ontology, you could use 
TextToOnto (or the most recent version called Text2Onto). TextToOnto can 
automatically generate an ontology from a corpus of text documents. It 
can also create or prune relations and concepts in your existing 
ontology. I have used TextToOnto in my research to see if an 
automatically generated ontology could improve the recall and precision 
of Sesei, a semantic search engine that uses CGs. I have found out that 
Sesei with a TextToOnto ontology yields a better recall and precision 
for queries concerning a particular field of knowledge.

TextToOnto is available at:

http://sourceforge.net/projects/texttoonto

and Text2Onto (I have to say that I am less familiar with this one) is 
available at  :

http://ontoware.org/projects/text2onto/

If you want more information about Sesei, you can check:

[Fwd: [peirce-l] Most serious Windows vulnerability ever]

I'm forwarding this on this very serious Windows vulnerability for those 
who still use it. GR

** Hackers exploit Windows flaw -- Kevin Allison, FT.com (The Financial Times) Published: Jan 2, 2006
** New flaw in Windows image handling -- -- Nate Anderson , _Ars Technica_, Jan 2, 2006
** Windows WMF Vulnerability News & Updates -- GRC, Steve Gibson

List,

Just an alert for those who may not yet be aware of the latest computer virus alert.

Computer hackers have now published the source code for an MS Windows security flaw for which Microsoft
still have developed no patch. All versions from Windows 98 through ME, NT, 2000, XP, and 2003 are vulnerable.

So, the current vulnerability and risk are the biggest ever seen. 

I'm using Mozilla which lets the user turn off the image loading (through "Edit, Security.."). It doesn't
integrate with Norton, though. I always have my email program set not to link to the Internet and not to
preview emails. I can't stop the stupid thing (MS Internet Explorer, of course) from showing images
altogether. Microsoft is "above" having options like "DON'T LOAD OR SHOW IMAGES."

I've downloaded and installed the non-Microsoft patch by Ilfak Guilfanov, which is supposedly
"suppresses all known exploitable vulnerabilities for anyone using Windows 2000, XP, server 2003, or
64-bit XP." The patch is supposed to work only for those versions of Windows, not for any other versions of
Windows. One is still supposed to disable the Windows Fax and Picture Viewer, because the patch works only
against _known_ exloitable vulnerabilities. I've gone to Start, Run, and disabled the Windows Fax and
Picture Viewer viewer file by typing "regsvr32 -u shimgvw.dll" and executing. After the vulnerability
is truly patched, presumably one will be able safely to reenable it. 

I can't vouch for the patch or its author. Anyway, it hasn't destroyed my computer so far. One is supposed to
remove it again (through add/remove in Control Panel) when one finally is able to get an official
Microsoft patch. 

Also, they say don't open any wmf files coming to you through the email. And turn preview off of course.

Best, Ben

*** Hackers exploit Windows flaw ***
By Kevin Allison in San Francisco, FT.com (The Financial Times) Published: January 2 2006 18:18 | Last
updated: January 2 2006 18:18, © Copyright The Financial Times Ltd 2005. 
http://news.ft.com/cms/s/0d644d5e-7bb3-11da-ab8e-0000779e2340.html

Computer security experts were on Monday facing the threat of a newly discovered vulnerability in
Microsoft's Windows operating system that could put hundreds of millions of PC users at risk of infection
by spyware or viruses.

The news marks the latest security setback for Microsoft, the world's biggest software company, whose
Windows operating system is a favourite target for hackers.

"The potential [security threat] is huge," said Mikko Hyppönen, chief research officer at F-Secure, an
anti-virus company. "It's probably bigger than for any other vulnerability we've seen. Any version of
Windows used by any company in the world is vulnerable right now."

The flaw, which allows hackers to insert malicious computer programs into seemingly innocuous image
files, was discovered last week.

But the potential for damaging attacks increased dramatically at the weekend after a group of computer
hackers published the source code they used to exploit it.

Unlike most attacks, which require victims to download or execute a suspect file, the new vulnerability
makes it possible for users to infect their computers with spyware or a virus simply by viewing a web page,
e-mail or instant message that contains a contaminated image.

"We haven't seen anything that bad yet, but multiple individuals and groups are exploiting this
vulnerability," Mr Hyppönen said, adding that every Windows system shipped since 1990 contained the flaw.

Microsoft said in a security bulletin on its website that it was aware that the vulnerability was being
actively exploited. But by early on Monday, it had not yet released an official patch to correct the flaw.

"We are working closely with our anti-virus partners and aiding law enforcement in its investigation,"
the company said. In the meantime, Microsoft said it was urging customers to be careful opening e-mail or
following web links from untrusted sources.

Meanwhile, some security experts were urging system administrators to take the unusual step of
installing an unofficial patch created at the weekend Ilfak Guilfanov, a Russian computer programmer.

Concerns remain that without an official patch from Microsoft, many corporate IT systems could remain
vulnerable as employees trickle back to work after the holiday weekend.

Microsoft could not be reached for comment.

*** New flaw in Windows image handling  ***
1/2/2006 1:18:31 PM, by Nate Anderson , Ars Technica
http://arstechnica.com/news.ars/post/20060102-5876.html

A newly-reported flaw in the way Windows handles images was successfully exploited over the New Year's
weekend, and no official patch is yet available from Microsoft. The problem stems from the way that
Windows deals with .WMF (Windows Metafile) images; a maliciously crafted image can execute code on any
Windows system, including XP SP2. All that's required to trip the payload is viewing a .WMF image locally
or on the web. An e-mail titled "Happy New Year" is already making the rounds
http://www.techworld.com/security/news/index.cfm?NewsID=5070&Page=1&pagePos=5&inkc=0 with
an attachment labeled "HappyNewYear.jpg" that is really a disguised .WMF image. Trusted web sites are
also capable of being compromised. The Internet Storm Center reports
http://isc.sans.org/diary.php?date=2006-01-01 that knoppix-std.org was compromised by the
addition of a frame that redirected browsers to a malicious .WMF file.

Because of the way that Windows handles images, the exploit can also be triggered by viewing a directory
containing a malicious file. It can also be tripped by desktop indexers such as Google Desktop Search.
E-mail plus Google Desktop Search is a particularly deadly combination, because Google may index the
file and release the payload even if you do not read it.

Obviously, those running non-Windows systems are not affected by the exploit, nor are those who use
hardware-based Data Execution Prevention (DEP). All other Windows systems are affected, no matter if
you're running Internet Explorer or Firefox. Though Microsoft has known about the problem since
December 28, 2005, when they sent out news of the vulnerability by e-mail, they have yet to release a patch
for the problem (one may not appear before January 9). Antivirus scanners provide some measure of
protection, but several of them still do not catch the problem. The Internet Storm Center is hosting an
unofficial patch http://handlers.sans.org/tliston/wmffix_hexblog13.exe for the problem, but they
also advise users to unregister shimgvw.dll (the Windows Fax and Picture Viewer) from their systems
(regsvr32 -u %windir%\system32\shimgvw.dll). This should reduce the possibility of exposure from
web-based images.

Of course, the people running the Storm Center know that many users, especially in corporate
environments, are reluctant to install an unofficial and unsupported patch. Still, they encourage you
to install it anyway, and ask for something rare on the internet-trust.

66~~~~~~~~
"The Microsoft WMF vulnerability is bad. It is very, very bad.

We've received many emails from people saying that no one in a corporate environment will find using an
unofficial patch acceptable.

Acceptable or not, folks, you have to trust someone in this situation.

To the best of my knowledge, over the past 5 years, this rag-tag group of volunteers hasn't asked for your
trust: we've earned it. Now we're going to expend some of that hard-earned trust:

This is a bad situation that will only get worse. The very best response that our collective wisdom can
create is contained in this advice - unregister shimgvw.dll and use the unofficial patch. You need to
trust us." 
~~~~~~~~99

The unofficial patch does not support Windows 95, 98, or ME, however, so those users have only limited
defenses against the exploit. The .WMF exploit illustrates the dangers in still running Windows 98,
which will soon come to the end of its supported lifecycle and will no longer receive any official patches.
When a vulnerability like this comes to light a year from now, no fixes will be forthcoming from Microsoft
and the possibility of infection will be high.
================================

*** Windows WMF Vulnerability News & Updates ***
GRC, Steve Gibson
http://www.grc.com/sn/notes-020.htm

Quick Background:

 The active exploitation of a very serious vulnerability in all versions of Windows was discovered in late December.

 Word of this spread rapidly through the hacker community - many of whom where presumably on holiday
vacation from school, bored, and looking for something to do.

 So several days later nearly one hundred different instances of exploitation of this newly discovered
vulnerability had been found.

 Note that this is not a "new vulnerability" - it (and perhaps other similar bugs) have been lying unknown in
Windows since 1991. What's "new" is the discovery of this long-present vulnerability in Windows'
metafile processing.

 Almost immediately there were reports of an MSN Messenger worm, and now F-Secure is reporting that "Happy
New Year" SPAM eMail is carrying an exploit.

 Anti-Virus vendors quickly updated and began pushing out their A-V signature files. These have been
effective, but a new very flexible exploit generation tool has appeared that's able to create so many
different variations of the exploit that A-V signatures are having trouble keeping up.

 Microsoft responded with an acknowledgement of the problem
http://www.microsoft.com/technet/security/advisory/912840.mspx which included a very weak
workaround (the shimgvw.dll unregistration) that provides very little protection. There's is not a
cure, and it is not known how long the Windows user community will now be waiting for a true patch from Microsoft.

 Ilfak Guilfanov (see GREEN box below) produced a highly-effective true patch
http://www.hexblog.com/security/files/wmffix_hexblog13.exe which successfully suppresses all
known exploitable vulnerabilities for anyone using Windows 2000, XP, server 2003, or 64-bit XP. No patch
is available for Windows 95, 98, ME or NT, and none is expected to be forthcoming. But anyone using Windows
2000, XP, server 2003, or 64-bit XP should IMMEDIATELY install Ilfak's exploit suppressor into all of
their systems.

Other Updates

 A special (short) edition of "Security Now!" - On Sunday, January 1st, I phoned into Leo Laporte's KFI "Tech
Guy" radio program to inform him and his radio audience of the availability of Ilfak's new patch and real
solution. Leo produced a special edition of our weekly "Security Now!" audio podcast. Since this was by
telephone the audio quality is not great, but the high-quality and lower-quality MP3 audio files are
available here:

    Higher-quality (larger) KFI Radio program update (64 kbps, MP3, 5.4 MB)
    Lower-quality (smaller) KFI Radio program update. (16 kbps, MP3, 1.4 MB)

 Ilfak has produced a WMF Vulnerability Checker - Many users want to verify that their "exploit suppressed"
systems are now safe to use. And others want to see whether their anti-virus A-V systems are now detecting
some WMF exploit code. So Ilfak has produced a simple WMF Vulnerability tester:

    Download Ilfak's WMF Vulnerability Checker (3.6 kb)
http://www.hexblog.com/security/files/wmf_checker_hexblog.exe

You can read more about his checker, and users' experiences, on his Vulnerability Checker blog page.
http://www.hexblog.com/2006/01/wmf_vulnerability_checker.html

 An important Note about A-V signatures: As useful as anti-virus protection is as a first line of defense,
new WMF exploits are succeeding at bypassing them. So A-V cannot be relied upon. The only safe measure is to
install Ilfak's vulnerability suppression solution until Microsoft has updated the GDI32.DLL file and
permanently resolved this problem.

New High Quality Temporary
WMF Exploit Patch Available!

Ilfak Guilfanov http://www.hexblog.com/2005/12/wmf_vuln.html , well known in "reverse engineering"
circles for his wildly popular IDA Disassembler, needed a temporary patch for his own system due to the
seriousness of the WMF vulnerability (see RED box below) . . . so he wrote one!

Download Ilfak's Temporary WMF Patch
http://www.hexblog.com/security/files/wmffix_hexblog13.exe

291 kb - for Windows 2000, XP, 64-bit XP and 2003 server

 This safely and "dynamically patches" the vulnerable function in Windows to neuter it and, after
rebooting, renders any Windows 2000, XP, 64-bit XP and 2003 systems completely invulnerable to
exploitation of the Windows Metafile vulnerability.

 Please Note: Unlike the "DLL unregister" recommendation offered by Microsoft (see RED box below) Ilfak's
patch completely eliminates the vulnerability. Therefore, until Microsoft is able to update and repair
their vulnerable GDI32.DLL, this is what you should use. You do NOT need to unregister the DLL as described
in the RED box below.

 You SHOULD REMOVE THIS PATCH to restore full functionality to Windows Metafile processing once WIndows
has been officially updated and repaired.

To Remove: Simply open the Windows Control Panel "Add/Remove Programs", where you will find the "Windows
WMF Metafile Vulnerability HotFix" listed. Remove it, then reboot.

Newly Discovered & Immediately
Exploited Windows Vulnerability
A serious new remotely exploitable vulnerability has been discovered in Microsoft Windows' image
processing code.

UNTIL THIS IS REPAIRED BY MICROSOFT, ANY ATTEMPT TO DISPLAY A MALICIOUS IMAGE IN WINDOWS COULD INSTALL
MALICIOUS SOFTWARE INTO THE COMPUTER.

 This is a so-called "0-day vulnerability" because exploits for the vulnerability appeared before any
updates or patches were available.

 All versions of Windows from Windows 98 through ME, NT, 2000, XP, and 2003 are known to be vulnerable, and a
large and rapidly growing number of malicious exploits (57 at last count) are already circulating in the
wild. They are being actively used to install malware and Trojans into user's machines. Viruses and worms
are expected to appear shortly.

 Although NOT a complete solution, Microsoft has recommended temporarily disabling the automatic
display of some images by the operating system and web browser. This can be done, as detailed below, by
"unregistering" the "SHIMGVW.DLL" Windows DLL. THIS IS NOT A COMPLETE SOLUTION, but it significantly
lowers the risk from this vulnerability from web surfing.

For Windows 2000, XP, 64-bit XP and 2003 server

The temporary patch described above is a FAR superior solution. ONLY use the de-registration approach
below if you are unable to use Ilfak's temporary patch.

 Do not open any "WMF" -- Windows Metafiles -- you receive by eMail, and reports are that other file types may
also be dangerous.

 Anti-virus companies have responded to this, so update your anti-virus signature files for updated protection.

You should IMMEDIATELY disable Windows' use of this
vulnerable DLL until patches from Microsoft are available.

Note that this WILL temporarily disable the "Thumbnail" view
in Windows Explorer and Window's Image and FAX viewer. This is
by design, since these viewers are no longer safe to use until a
non-vulnerable file has been produced by Microsoft and installed.

To immediately disable the vulnerable Windows component:

 Logon as a user with full administrative rights.

 Click the Windows "Start" button and select "Run..."

 Enter the following string into the "Open" field:

regsvr32 -u shimgvw.dll

(You can copy/paste from this page using Ctrl-C/Ctrl-V)

 Click "OK" to unregister the vulnerable DLL.

If all goes well, you will receive a confirmation prompt, and your system is now safe. No need to reboot, but
you might want to just to be sure that any possible currently loaded instance is flushed out.

To eventually re-enable the "SHIMGVW.DLL" component:

 Logon as a user with full administrative rights.

 Click the Windows "Start" button and select "Run..."

 Enter the following string into the "Open" field:

regsvr32 shimgvw.dll

(You can copy/paste from this page using Ctrl-C/Ctrl-V)
Same as the one above, but no "-u" for "uninstall".

 Click "OK" to re-register the (hopefully) non-vulnerable DLL.

RE: RE: [PORT-L] Collaborative tool based on Concept Maps

Happy New Year, everybody,

I have further examined the Cmap software, and must say I am even more
impressed. This is one of the few concept mapping tools that seems to work
in practice, with a special focus on collaborative modeling, and even
better, completely free of charge. 

For the purpose of modeling our research as a community, we can make use of
what in Cmap-lingo are called 'Places'. These are public servers which host
concept maps of many different kinds. To host the CG Cmaps, I have created a
'Knowledge Model' called "Conceptual graphs" at the IHMC Public Cmaps
server. Such a knowledge model can contain a collection of several related
Cmaps.

To show proof of concept (map), I have created two sample maps within this
knowledge model:

- "conceptual graphs": rough summary of the most important concepts
introduced in the first 96 pages of John's 1984 book. 

- "conceptual graphs references": the references (for now, only containing
the 1984 book reference) used in the other map. 

One powerful feature is that concepts can link to maps and other resources,
such as web pages, and even to specific concepts in other maps. Here, I have
only included one link from the concept "references" in the Cmap "conceptual
graphs" to the Cmap "references".     

Another powerful feature is that the public servers not only make the maps
accessible (for which the user needs to install the Cmap software), but also
the html version.

http://skat.ihmc.us/servlet/SBReadResourceServlet?rid=1136298262912_71798340
7_7029&partName=htmltext

This is a clickable map, try clicking the "references" concept.

In the original map (accessible with the Cmap software), you can also add
and read annotations and additional info. This additional info shows when
one does a mouse-over of a particular concept. For each concept, I have
added the source, e.g. "(Sowa, 1984, p.91)" and sometimes the definition.
This makes it easy to add hooks to the literature and other sources to look
up material. The web version does not allow for this, but this could be
resolved by, for instance, adding reference information as separate concept
nodes. I have chosen not to do so in order not to clutter the map even more.

The current maps should not be taken too seriously, they are just for proof
of concept. There are many other interesting features (like Autolayout,
Nested Concept, splitting maps) which can be useful in making the Cmaps more
manageable. The next step will be to develop a _process_ to develop
collaborative maps more systematically. Questions that need to be answered
include:

- How to deal with versioning? Do we keep old maps, or overwrite them in the
Places? Do we keep different versions by different people, or should we try
to integrate them into one consensual map? 

- What editorial, access rights etc. need to be granted to whom?

- What conventions are needed for referencing, naming concepts and
relations, use of fonts, etc.?

- How to organize maps into maneagable units? How large can they become?
What criteria to use for splitting them? 

Alex Heussner has offered to help with designing some kind of "process". We
will get back to you in due time. Looking forward to any suggestions!

Aldo

PS My mailer broke the url of the Cmap into two, make sure you use the full
