Can oracle text be used to compare documents?

lets say that i 've some documents stored in binary(LOB). can oracle text be used to compare documents and show their similarity on the basis of their content. how would i be able to compare documents using Oracle text. does it require mining algorithm like neural network. please help.
thanks for reading.

Thank you for your interest in my question. Let me see whether I can further clarify it. In an ordinary PDF document, assume that I have a picture of a user interface for microsoft Word. The common method for identifying items in the picture, such as a toolbar, would be to either:
--use a callout labeled "toolbar" that points to the toolbar
or
--use a callout labelled "A" and have a caption underneath the picture that says: A) toolbar.
What I would like to do is have text underneath the picture such as:
"The major features of the interface shown above are:
toolbar
main menu
status bar
formatting menu"
such that, when the user clicks one of the bullet items, the object becomes highlighted in the picture. The bullet list also needs to be translatable into Japanese. So, as far as I know, it can't be part of the swf file. Or can it?

Can anybody explain about use of 57F4 document

can anybody explain about use of 57F4 document.

In Indian subcontracting process when you issue materials to a subcontractor, you need to keep track of what materials you have issued and when they have to be returned by subcontractor. The reason for this close monitoring has to do with Indian tax law. Under excise law 57AC, when you send materials to a subcontractor for processing, you are not required to pay any excise duty, even though the materials have left your premises. However, if the materials have not been returned to you within 180 days specified by the law, you will have to reverse any excise credit that you posted when you have purchased the materials. When you send material out of your factory premises you need to send with 57F4 Challan. In this process you are going to do the same.
The Process Flow would be
u2022     Creating Subcontracting Purchase order
u2022     Message Output for Purchase Order
u2022     Transferring of Components to Subcontractor
u2022     Creating of subcontracting Challan
u2022     Goods Receipt for Purchase Order
u2022     Reconciling Subcontracting Challan
u2022     Completing/Reversal/Re-Credit Subcontracting Challan
u2022     Logistics Invoice Verification

Should Oracle Text be used here?

Hi,
We are developing a search feature for a bank that has thousands of documents. Each document has a set of free-form comments written by multiple bank officials. The comments are in a table in a Oracle 9i database. The comments can be 10 to 10000 characters. The actual documents are not available in the database. Only a document identifier is kept in the table containing the comments.
The search engine will have single-word as well as phrase searches. Do you think using Oracle Text is the best approach for such a serach facility?
Thanks
Yash

Sameer,
I guess I was right about it being personal. I do feel like we're getting somewhere though! DETAILS!!!
This isn't about me, you, or Text. The posts are to help those that need assistance, and for some of us (like me) to gain some exposure to problems I have not run into. You'll see a fair amount of research goes into many people's posts here.
Your earlier write-up telling the person to stay away provided no specifics about your situation. It was alarmist. They might have totally different requirements than you, so it pays to ask follow-up questions to find out if they are going to hit what you did.
I don't mind 'talking crap' about something so long as it is specific and can be addressed, or people can find situations where it should/should not be used by comparing their system to yours. If I tell you that cars suck because they break down, it isn't terribly useful to anyone. If I tell you that the 1982 Pontiac Bonneville's transmission needed to be replaced 13 times since I bought it...that kind of detail might be of some use to someone with that car. This is what I was soliciting from you.
What do we have from your last post:
* 9.2.0.5
* Millions of user's per day
* Peak time the box was only 5-10% idle
* The problem was with queries on a CONTEXT index
(rather than the indexing process itself)
* You couldn't use CTXCAT because of application requirements
Two things you said that I will agree with.
1) CONTAINS queries can be costly. There are some ways to improve the performance if you post more detail about your requirements. This is the first time you mentioned that you were using the CONTEXT index instead of CTXCAT...good information. It would indicate that your 'this totally sucks' gut response from earlier is from the perspective of CONTEXT and doesn't extend to the other index types (or am I mistaken?).
2) 10g has improved upon some things. Later patchsets on Release 1, and the newly available Release 2 have a different filter as well. 9i made some major changes from prior releases though, so if 9i is the only option, I'd still take it.
If you are interested in continuing, I'd like to find out how many indexes, the number of documents indexed, the size of the index tables and data tables, and some more about the application. Give us your best shot.
As for hurting the ego...I'll still sleep well tonight. I would just like to see this remain a constructive place for people to post questions and try out solutions. That can't happen if the replies are a blanket 'stay away' without justification or a matching of requirements to problems.
Finally, feel free to post to anything I participate in...just remember that I'm not shy (and neither are you it seems), so if a debate happens it will likely be lively.

Oracle Text - Problem with filtering binary documents (.doc, .pdf, etc...)

Hi, I have a problem with filtering binary documents (.doc, .pdf, etc...). I use SQL*PLUS for remote access to Oracle 10.2 on Linux and I create table:
CREATE TABLE test (id NUMBER PRIMARY KEY, text VARCHAR2(100));
I insert to this table:
INSERT into test values(1, 'PATH/text1.doc‘);
INSERT into test values(2,'PATH/text2.doc‘);
and then:
CREATE INDEX test_index ON test(text) indextype is ctxsys.context
parameters (’datastore ctxsys.file_datastore
filter ctxsys.auto_filter’);
Message "Index created" is displayed, but objects: DR$test_index$I, DR$test_index$K, DR$test_index$N, DR$test_index$R and DR$test_index$P are empty => index wasn´t created probably.
I don´t know, where is bug, either bug is somewhere in this code or on the server (wrong installation oracle or constraint privileges). Do you know in what is bug?

The following is an excerpt from the 10g online documentation. Note the items that I have put in bold.
"FILE_DATASTORE
The FILE_DATASTORE type is used for text stored in files accessed through the local file system.
Note:
FILE_DATASTORE may not work with certain types of remote mounted file systems.
FILE_DATASTORE has the following attribute(s):
Table 2-4 FILE_DATASTORE Attributes
Attribute Attribute Value
path path1:path2:pathn
path
Specify the full directory path name of the files stored externally in a file system. When you specify the full directory path as such, you need only include file names in your text column.
You can specify multiple paths for path, with each path separated by a colon (:) on UNIX and semicolon(;) on Windows. File names are stored in the text column in the text table.
If you do not specify a path for external files with this attribute, Oracle Text requires that the path be included in the file names stored in the text column.
PATH Attribute Limitations
The PATH attribute has the following limitations:
If you specify a PATH attribute, you can only use a simple filename in the indexed column. You cannot combine the PATH attribute with a path as part of the filename. If the files exist in multiple folders or directories, you must leave the PATH attribute unset, and include the full file name, with PATH, in the indexed column.
On Windows systems, the files must be located on a local drive. They cannot be on a remote drive, whether the remote drive is mapped to a local drive letter."
With accessible paths and files, you get something like:
SCOTT@orcl_11g> CREATE TABLE test (id NUMBER PRIMARY KEY, text VARCHAR2(100));
Table created.
SCOTT@orcl_11g>
SCOTT@orcl_11g>
SCOTT@orcl_11g> INSERT into test values(1,'c:\oracle11g\banana.pdf');
1 row created.
SCOTT@orcl_11g> INSERT into test values(2,'c:\oracle11g\cranberry.pdf');
1 row created.
SCOTT@orcl_11g>
SCOTT@orcl_11g> CREATE INDEX test_index ON test(text) indextype is ctxsys.context
2 parameters ('datastore ctxsys.file_datastore
3 filter ctxsys.auto_filter');
Index created.
SCOTT@orcl_11g>
SCOTT@orcl_11g> select count(*) from dr$test_index$i
2 /
COUNT(*)
608
SCOTT@orcl_11g> In the following, I used a non-existent path and non-existent file name, which produces the same results as when you use a remote path that does not exist locally.
SCOTT@orcl_11g> CREATE TABLE test (id NUMBER PRIMARY KEY, text VARCHAR2(100));
Table created.
SCOTT@orcl_11g>
SCOTT@orcl_11g>
SCOTT@orcl_11g> INSERT into test values(3,'c:\nosuchpath\nosuchfile.pdf');
1 row created.
SCOTT@orcl_11g>
SCOTT@orcl_11g> CREATE INDEX test_index ON test(text) indextype is ctxsys.context
2 parameters ('datastore ctxsys.file_datastore
3 filter ctxsys.auto_filter');
Index created.
SCOTT@orcl_11g>
SCOTT@orcl_11g> select count(*) from dr$test_index$i
2 /
COUNT(*)
0

I have moved from a G5 Powermac to an Intel Mac Pro and am porting over Items from a Backup HDD. How can I access and use drawings and documents created on the PC computer on the Intel computer ?

I have moved from a G5 Powermac to an Intel Mac Pro and selectively porting over items from a backup hard drive.
How can I access and use documents and drawings created on the PC based computer ?

Clarisworks, you need Appleworks, which will only work with Mac OS X10.6.8 or earlier. See this tip if you must go newer. Mac Pros with newer hardware configuration than July 20, 2011 can't use Mac OS X 10.6.8 or earlier without this tip and then it would be Mac OS X Server. I'm not sure if the new black Mac Pro supports that configuration or not.
iPhoto, there is an iPhoto for all versions of Mac OS X.
iTunes, there is an iTunes for all versions of Mac OS X. Note with iTunes versions 11 and later, which are needed for syncing with iOS 7 or or later, you will lose coverflow, if you liked that feature. Sadly you can't run an older version of iTunes from within Mac OS X 10.9 or later.
Sketchup: http://help.sketchup.com/en/article/60107 shows the versions that will work with intermediate Mac OS X versions, and this shows the latest version: http://help.sketchup.com/en/article/36208 be sure to click on the operating system you choose to use.
GIF - Viewing GIFs Apple's Preview can do that. Editing them, I like http://www.lemkesoft.com/ Graphicconverter.
DMG is able to be opened by all versions of Mac OS X. This are just "disk images" which store programs on a virtual disk that will open when double clicked. Frequently you'll find the installer of the said program inside. To find out if the program itself is compatible with 10.7 through 10.9, see http://www.roaringapps.com/
Otherwise see the resources on:
https://discussions.apple.com/docs/DOC-2455
If you end up deciding to stick with Snow Leopard.

Can a Text Variable be shared across document in a Book?

I'd like to define a single instance of a text variable and have it available to all documents in a Book (.indb). Can't figure out how. Is this possible?
InDesign CS5.5 (both mac & pc versions)

InDesign can't, automatically.
But it is an option in the Book panel -- you can enable text variables to synchronize along with loads of other stuff. Then all it needs is a quick click on the Synchronize button.
Just make sure you only enable the items you really want to sync.

Can ordinary text be used to control a flash function?

Everyone,
I'm new to flash but I have a fairly specific problem I'm trying to solve. Here goes:
We create documentation in FrameMaker 7.2 and publish it in PDF format. We have a lot of screenshots in our documents that each contain several objects that I would like to point out to users. Historically, we'd just use captions such as "a) main menu; b) drawing toolbar c) formatting menu".
I'd like to enable users to click an item in the caption and have the corresponding item in the screenshot to become highlighted or circled so that users can see it easily. It seems like it should be that hard to do in Flash; but, here's the catch: the caption text must be ordinary text. Since we localize all our documentation, our localization vendor must be able to read the caption using there scanning software.
Can this be done?

Thank you for your interest in my question. Let me see whether I can further clarify it. In an ordinary PDF document, assume that I have a picture of a user interface for microsoft Word. The common method for identifying items in the picture, such as a toolbar, would be to either:
--use a callout labeled "toolbar" that points to the toolbar
or
--use a callout labelled "A" and have a caption underneath the picture that says: A) toolbar.

"The major features of the interface shown above are:
toolbar
main menu

Oracle text clustering - use of Stemming

Hi,
I am using K-means to cluster a set of documents. But I am unable to set the clustering algorithm parameters to use stemming for the tokens. The clustering algorithm uses 'move', 'moving', 'moves', 'moved' as separate words and clusters the documents into different clusters. I would like to group all the documents that contain 'move', 'moving', 'moves', 'moved' into a single group by using the stem 'move'. I am unable to do this so far. In case any of you have some ideas, please suggest.
I use the following preferences and attributes to create a text index:
BEGIN
CTX_DDL.DROP_PREFERENCE ('test_lex');
CTX_DDL.CREATE_PREFERENCE ('test_lex', 'BASIC_LEXER');
CTX_DDL.SET_ATTRIBUTE ('test_lex', 'INDEX_STEMS', 'ENGLISH');
END;
drop index temp_idx;
CREATE index temp_idx ON temp(text1) indextype is CTXSYS.CONTEXT parameters ('WORDLIST CTXSYS.BASIC_WORDLIST LEXER test_lex SYNC (ON COMMIT)');
And below is the code I use to cluster the documents:
create table temp0 (docid NUMBER, clusterid NUMBER, score NUMBER);
create table temp1 (clusterid NUMBER, descript varchar2(4000), label varchar2(200), sze number, quality_score number, parent number);
begin
ctx_ddl.drop_preference('my_cluster');
ctx_ddl.create_preference('my_cluster','KMEAN_CLUSTERING');
ctx_ddl.set_attribute('my_cluster','CLUSTER_NUM','10');
ctx_ddl.set_attribute('my_cluster','STEM_ON','FALSE');
ctx_output.start_log('my_log');
ctx_cls.clustering('temp_idx','seq','temp0','temp1','my_cluster');
ctx_output.end_log;
end;
Thanks!

Make the following true
ctx_ddl.set_attribute('my_cluster','STEM_ON','FALSE');
i.e.
ctx_ddl.set_attribute('my_cluster','STEM_ON','TRUE');
and then create the clusters. Also as you have already done, the lexer should have INDEX_STEM on

Oracle TEXT and using 'ABOUT' as a string literal, not a command

We have a context index on a NAME column, and we're getting an error when searching on the string
CONTAINS(name, '%ALL ABOUT TRAVEL%') > 0A query on ALL ABOUT, and ABOUT TRAVEL works, but the entire phrase causes a problem. I've since found that ABOUT is a keyword when using CONTAINS( ).
So, is there a way to escape ABOUT, include it in double quotes, etc, so that it gets treated as a string literal?
Thanks,
--=Chuck

Should've searched google more before posting ... :(
Maybe this'll help someone else out, though:
CONTAINS(name, '%ALL {ABOUT} TRAVEL%') > 0

Document management system using oracle text

i plan to create document management system using oracle text with following features
1) document comparision
2) document search
and more...
can oracle text be used to display documents of various formats by converting them to HTML. and can search keywords be highlighted in the document.
please help!

Have you ever considered doing this in Oracle Application Express (free on top of the Oracle database)? How about something like:
http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm
Index the files using the CONTEXT index, and perhaps the docs' meta with it using the Oracle Text MULTI_COLUMN_DATASTORE, and then when you write your query for a report on the documents include a search string.
I've created a number of APEX-based document management systems and it is quite easy once you get the hang of using this environment. I suggest looking at some of the tutorials/how-to documents and you'll be on your way quickly.
Start with the upload application. Once you can get your documents in, create a report that shows everything except the document. Verify all of this works correctly.
Add some "items" to the page for the report, and include them as bind variables in the where clause.
After that, add your Oracle Text index to the database, and toss in a "text-field" item to the APEX page. Modify your report query, adding the CONTAINS clause, and use the newly created item as a bind variable. There's your keyword search.
Linking to Oracle Apps is done through API's and may be over database links.
Hope it helps. Though not a step-by-step how to document, this should point you in the right direction. Get familiar with APEX as that covers most of what you described.
