Knowledge Base vs. thesaurus

Hi all,
I'm comparing KB vs. thesaurus usage.
The KB is a structure of themes - constituted of either single words or phrases. Relations are either hierarchical or generic.
Usage occurs by ABOUT(<theme>).
The thesaurus is a structure of terms - either single word or made up of a phrase. Relations are either hierarchical or generic, or related to synonyms. Usage occurs by several operators.
From these definitions I would guess that:
- these structures can almost represent the same data, indeed manuals explain how to extend the KB using thesauri.
- the operator "ABOUT(<theme>)" should be equivalent to "<theme> OR NT(<theme>) OR RT(<theme>)"
So the question is: why using a KB, provided that thesauri appear far more flexible ? Multiple thesauri can coexist, even for the same language. API are provided to edit them. On the other hand, the KB is an all-or-nothing precompiled structure, bound to English and French.
What's wrong with this reasoning ? What do we gain while using a KB ?
Thanks for any comment.

What is differnce between the forum and the knowledge base ?
As far as I see the forum is where users ask questions and answers are provided, often by NI representatives.
Answers in the forums are mostly answered by non-NI employees.  We have a lot of volunteers who just enjoy helping.  But the AEs inside of NI are always watching the boards.
The Knowledge Base is not really a place to ask questions.  It is where NI empolyees create a white paper based on very often asked questions.  You have little to no interaction in there.  The forums are wide open for anybody to chime in.
But I do like your idea that when searching the forums, a search in the KB is also done.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions

  • Problem in creating a new knowledge base file

    Dear experts,
    I should like to create a new knowledge base file. I use the Oracle version 9.2 and the OS is Windows 2000. I have created the thesaurus with
    ctxload -user ctxsys/ctxsys -thes -thescase y -name DEFAULT -file xx.xx
    and the language setting:
    NLS_LANG=HUNGARIAN_HUNGARY.EE8MSWIN1250
    During the compile operation
    ctxkbtc -user ctxsys/ctxsys -name DEFAULT
    i get the following error message:
    DRG-52110: Error in writing extended knowledge base
    DRG-11101: drelcHU.dat open error
    Before the ctxkbtc command execution, I have created an empty directory for the expected .dat file:
    ctx/data/hulx
    with full control for every OS users.
    What is missing or false in the commands? Where could I learn more on this special topic?
    Many thanks for any help.
    Best regards
    Laszlo

    meanwhile i have found the solution :-), The name of the empty directory must be
    xxlx
    and not
    hulx

  • Error in accessing Knowledge base  + oracle text 11g

    Hi All,
    I am using oracle text 11g.
    I had installed a knowledge base and it was working fine(bcos i was able to generate themes and gists), i wanted to load a 'default' thesaurus, i created a 'default' thesaurus and from cmd prompt i gave 'ctxload' command, then it asked for user(i logged in as ctxsys credentials), name (thes default),file( thes path), but after this i got below error
    connecting...
    DRG-11510: encountered unrecoverable error on line1
    ORA-00931: missing identifier

    unknowingly after this i gave 'ctxkbtc' command and proceeded further and i cancelled this action by closing cmd prompt.
    after this, now i am not able to create themes or gists, i am getting the below error while creating themes.

    Thanks in advance.

    Hi,
    You can try running ctxkbtc once more with revert option.
    -revert
    Reverts the extended knowledge base to the default knowledge base provided by
    Oracle Text.
    Make sure to set NLS_LANG variable before running it
    If you have already solved this issue, if possible share the solution to this forum too.

  • About query not using extended knowledge base

    Hello,
    I compiled a small thesaurus to the knowledge base:
    ctxkbtc -user dcenter/dcenter -name THES_PLACE
    It contains:
    GERMAN
    USE FEDERAL REPUBLIC OF GERMANY
    UF FRG
    BT EUROPE
    NT BAVARIAN
    I have 2 record, 1 containing GERMAN, 1 containing BAVARIAN.
    Field is indexed with a context index, and the index is synchronized.
    I'm using 8.1.7.2 english.
    Using an ABOUT operator, I always get 1 hit.
    SQL> select count(*) from file_info where contains (places, 'about(BAVARIAN)') > 0;
    The (9i) doc says:
    When you augment the existing knowledge base with your new thesaurus, you query with the ABOUT operator which implicitly expands to synonyms and narrower terms.
    How can I get the ABOUT query to expand to the narrower term in 8.1.7.2? Is this a bug, do I have to upgrade, or am I missing something?
    Thanks

    Hello.
    Did you load the supplied english thesaurus as your DEFAULT thesaurus using the command line utility ctxload (or some other method)?
    I had the same experience until I loaded the sample thesaurus in $ORACLE_HOME/ctx/sample/thes/. Now my ABOUT and SYN queries work as expected though I still have a concern about the incomplete nature of the sample thesauri (I'll open a new thread on that topic).
    Hope this helps.

  • ABOUT query not affecting results or not using knowledge base

    Hello again,
    Another question here,
    I've searched through the forum and have found other
    posts on the same problem but no solutions, though
    the problem isn't always the primary topic of the
    forum. I've put this post up to hopefully put this
    to rest as I'm pretty sure this is just a
    configuration issue.
    I am using an ABOUT operator in a CONTAINS query and
    the query seems to return the same results as the
    same query without the about operator, eg:
    SELECT SCORE(0) AS scr,
    file_repository.file_id,
    file_repository.file_title
    FROM file_repository
    WHERE CONTAINS(index_url, 'ABOUT(australia)', 0) > 0
    versus
    SELECT SCORE(0) AS scr,
    file_repository.file_id,
    file_repository.file_title
    FROM file_repository
    WHERE CONTAINS(index_url, 'australia', 0) > 0
    I have included documents based on the default
    knowledge base should be found. For example I have
    three documents, one containing the term 'Tasmania'
    another containing 'Australia' and a third with
    'Pacific Area'. The first query above should return
    all three of these documents, but it only returns
    the one containing 'Australia'.
    I have used other examples from the default knowledge
    base and have had no success. I have not attempted to
    extend the knowledge base with a thesaurus as, from
    what I can tell, I shouldn't need to do this for it
    to work.
    Any help would be much appreciated.

  • Intermedia knowledge base

    Hello,
    I'm looking to Intermedia capabilities and I need some help.
    On oracle 8.1.6:
    I created a theme index using LEXER preferences:
    ctx_ddl.create_preference('mylex', 'BASIC_LEXER');
    ctx_ddl.set_attribute('mylex','index_themes','YES');
    ctx_ddl.set_attribute('mylex','index_text','NO');
    ctx_ddl.set_attribute('mylex','theme_language','ENGLISH');
    I also created a table to store my themes and I populated it with the command ctx_doc.themes('index','doc_id','table_res',full_themes=>TRUE)
    Themes are added to the table, but I don't have the full_theme for themes that are yet in the knowledge base.
    Did I forget something? How can I be sure that the knowlegde base is present.
    thanks for your help.

    Hi Omor, My thesaurus is not big right now as I am experimenting with the sample provided. I am using queries as mentioned in the sample and as mentioned in the sample (CTX_DOC.THEME). I am using Extended admin tool (GUI) provided with enterprise manager V2.2.0.0.0, But it does not seem to accept the new additions to the knowledge base. Do I have to use any additional script or additional installation. I have 8i V8.1.7. Please suggest.

  • Since cahnging FIOS Internet provider, which required a router to go in front of "AirPort" I have a blinking yellow on the AirPort and suggested editing in AirPort utility to cahnge from Double NAT to "Bridge Mode" my knowledge base is not clear as t

    How do I clean up my new FIOS connection? I just cahnged ISP Fios and they reqquired a router of thier own in front of my AirPort Extreme. Since then I have blinking yellow light on the AirPort and AirPort utility keeps promting for an edit. Suggests canging from NAT to "Bridge mode". Obviuosly U have some internet or this post would not go anywhere, my knowledge base is not enought to feel comfortable with changing the settings. Correctly editing can be tricky, so how do I make necessary changes?

    How do I clean up my new FIOS connection?
    The FIOS router needs to be in Bridge Mode to prevent the Double NAT error from occurring when two routers are both fighting with each other for control of the network.
    Unfortunately, the likely problem from the FIOS side is that FIOS support will either tell you that their router cannot be configured to operate in Bridge Mode, or if it can, they will not tell you how to do it.
    But, it could not hurt to check with FIOS to see if anything might have changed recently in this regard, so your first call would be to FIOS support.
    If you cannot change the FIOS router to Bridge Mode, the alternate plan would be to change the AirPort Extreme to Bridge Mode. If you are using the Guest Network feature on the AirPort Extreme at this time, that feature will not work correctly when the AirPort is set up in Bridge Mode.

  • Update Knowledge base on Production with Dev Server

    Hi Samir,
    Stopping the e-mails to be sent out shouldn't be a problem in this system I think. You can still test everything, without the business getting confused. If you want to see if an e-mail is correct you can still check it in transaction SOST without it being sent.
    Otherwise inform the business about e-mails sent form different systems and add the system name in the e-mail message so they know from which system the e-mail is comming and if they have to respond.
    Regards,

  • Repair Disk Permissions utility stalled - I have read the knowledge base

    I have researched the knowledge base and search for posts on this and cannot find answer: Running 10.4 at the latest version. used the original install 1 disc I received with Tiger to repair disc permissions (like Apple support has told me to do in the past, but my current research said I do not need to do this unless certain parameters are met, and none of the parameters applied, but oh well, I am here anyway). Cold Boot from the original install disc 1 and slected the start up disk I use (I only have one start up disc/drive). Did a repair disc permissions and got a long running routine that reporting a lot of fixes, then the utility has stalled -- no progress on the progress bar. I "stopped" the process using the "stop repair" button (three times). The log reflected the utility stopped, but the progress bar still is blue and not moving (for a couple of hours). When I go to quity File >Disk Utility, it warns me that Disk Utility is running and this may make my system unstable/unsuable.
    QUESTION: CAN I JUST QUIT DISK UTILITY AND NOT HAVE ANY ADVERSE AFFECT ON MY IMAC DRIVE?

    Thanks for your advice, I still have an issue:
    -after the first repair disk permission "stalled" process, I exited Disk Utility and cold booted the machine after I had disconnected all external devices other than the original iMac keyboard
    -obtained the combo patch for 10.4.7 from the Apple download site (it had already been installed but I reinstalled per your advice)
    -re-applied the combo patch and then did another cold boot
    -ran Disk Utility from the original Tiger install #1 disk, and then selected "repair disk permissions" for my start up disk (I only have one)
    - process ran for 10 minutes or so then gave the following error message: "Disk Utility Error: Disk Utility has lost its connection with disk utility management tool and cannot continue. Please quit disk utility and re-launch disk utility"
    - I pushed the "stop disk permission repair" button, then quit disk utility, then cold booted the machine again.
    -re-applied combo patch as above, then cold booted the machine
    -ran disk utility from the original iMac install #1 disk, ran "repair disk permissions", and then received the same error message as above.
    - I then just quit Disk Utility and cold booted the machine again and went about my business. There does not seem to be any problem with the machine (was not before, but I ran repair permissions thinkging this was a routine maintenance taks that should be run)
    - in my prior search of the knowledge base, I found the following information about repair disk permissions:
    Location: http://discussions.apple.com/thread.jspa?messageID=607495&#607495
    How often should I Repair Permissions?
    You do not need to Repair Permissions on a regular basis.
    There are only three occasions you need to do this:
    1. When you have just installed something that required you to run an Installer, rather than just copying some software to a folder. This should be done for both Apple and non-Apple software.
    2. When you have been working on your OS X files or folders while booted from OS 9, or remotely connected via a non-OS X machine, since OS 9 and other systems do not handle OS X's permissions correctly.
    3. The other case is if your system is behaving strangely, when you should run Disk Repair from your CD followed by Repair Permissions. This is just to eliminate these things before going on to further trouble-shooting.
    Otherwise you can happily forget about Permissions!"
    So, it would appear I do not need to do anything else; the machine seems to be working properly. Is there anything else I need to do? thanks for the help! Bob

  • Three days ago I replaced an earlier Adobe Flash with version 10.1.85.3. This has not appeared in the list in Tools/Addons/Plugins to permit me to enable it in Firefox, and I can't find the answer in the knowledge base.

    Re. installing/enabling a Flash plugin
    1 I'm running Firefox version 3.6.10 on Windows XP SP3.
    2 Three days ago Secunia PSI informed me the installed version of Flash was a security threat so I uninstalled it then installed the latest version 10.1.85.3 . It appears in the Control Panel add and remove programs listings.
    3 As of 2 days ago BBC iplayer keeps telling me I need to install (latest version of?) Flash.
    4 I don't have this problem using my fallback Internet Explorer.
    5 Assuming I needed to enable Flash in Firefox I went to Tools/Addons/Plugins but Flash is not listed there.
    6 Firefox Support/Knowledge base/Installing the Flash plugin doesn't help - in step 2 I don't see the yellow 'Additional plugins are required...' bar when I go to the Adobe test page, but then why should I, it's already installed.
    6 What's going on - please help!

    I have the same problem as luiszamarreno. I tried using the following to update:
    sudo apt-get --purge remove adobe-flashplugin flashplugin-nonfree; sudo apt-get --purge autoremove; sudo apt-get clean; sudo apt-get upgrade; sudo apt-get --purge autoremove; sudo apt-get install flashplugin-nonfree
    Now I have the "flashplugin-nonfree" v. 10.01.218+really9.0.283.0ubuntu1 and it still doesn't work for the Facebook plugin. I get the notice it has crashed and needs to be updated. I also get a notice to update on the plugins page under tools --> addons. When I try that, it goes to the Adobe Web site, which I have seen on Ubuntu support sites that I do not want to upgrade from there.
    Does anybody have an answer to this?

  • Error 6 even after installing the software from Knowledge Base

    I am sure this has been on here before but I cannot find it.
    I am building a wedding video, one main menu, two sub menus with 7 chapters each.
    Check project reveals all set to go.
    tried to use the software recommended in the knowledge base but my system already has the latest version installed.
    SItuation-
    Burning Mpeg 2 BluRay Max quality
    All assets include two timelines (Trancscoded at Max quality), 3 menus, one sound track for menu.

    Could start over with Sonic DVDit HD or Scenarist but spent last night building this encore job.
    ERROR 6 I could use a little help on this one please.

    Thank you.
    I actually spoke to an employee at Park Av (Adobe headquarters) in San Jose this morning through a friend in the industry who added her on (There is someone there all the time he said).
    The simple fix according to her is just the cause that was in your link, it comes from transferring assets in and out. I had done that and the replacement cued up the error 6. There are other error 6's generated but that was the first question she asked.
    Anyway I really appreciate the response.
    Actually writing the disc now with just a few gigs to go on the Test Copy.

  • How does solutions knowledge base works?

    Hi,
    If you love working with Muse, BC would enhance it  as it completes Muse. WYSIWYG Design area in BC would give you the ultimate convenience designing the pages or templates.
    I would suggest that you create a Trial site in BC via Muse and go through the modules available. Modules are not synced with Muse but they will be rendered if you specify them with a correct reference ID's (as detailed here kb.worldsecuresystems.com/134/bc_1345.html) in Muse and then Publish.
    Business Catalyst is far more than a hosting provider. Business Catalyst is an online business platform, with email marketing, customer response management, eCommerce, forums, analytics, and more. Over time, Adobe Muse will grow to expose more of the power with Business Catalyst.
    Adobe Muse allows you to publish your temporary website to Adobe Business Catalyst at no charge for a 30-day trial period. This gives you the opportunity to send a live URL to your client for review. All sites in trial mode on Business Catalyst will include the Business Catalyst domain, example http://website.businesscatalyst.com. If you decide to take the site "live" by paying for the monthly hosting, you can transfer your own domain and remove the .businesscatalyst.com subdomain. Or you can export the HTML and host the final site with a hosting provider of your choice.
    You can have different users being an Admin on one site depending upon the permissions you set for them. + much more..
    Publishing sites to BC via Muse is seamless. So I recommend to test the trial publish. That way you can judge it best upto your expertise. Also check http://tv.adobe.com/watch/introducing-business-catalyst/getting-started-with-business-cata lyst-and-muse-creating-and-publishing-sites/ for more help.
    Hope that helps!

  • The Data quality knowledge base property is empty

    Hello 
    I build Knowledge base and published it successfully (using the DQS client wizard  normally )
    But when i open new ssis project and try to use the DQS component i can't use the knowloedge base i build , i get the message The Data quality knowledge base property is empty
    How can i be sure that i published successfully (any query on repository ?)
     What do i miss ?

    Hello,
    Use the Data Quality Client to check in the Open Knowledge Base
    screen if the knowledge base was published. To do so, click Open Knowledge Base
    in the home screen of Data Quality Client, and then check the Date Published column.
    Alternately, you can also check the PUBLISH_DATE column in the DQS_MAIN.dbo.A_KNOWLEDGEBASE
    table.
