Hi all,
Where can i find out the fuzzy logic dll file with version asp.net or else? How can i add the dll file into my program and using it?Please advised!
I am looking forward to hearing from you shortly and thanks a lot in advance.

Hello,
I am just wondering if someone out there has tried some Fuzzy matching on databases of large scale i.e - about 20 million contact records. Suppose I wanted to perform matching/ grouping to 10 000 incoming messages. How fast does this usually take? What is the dependence on the number of fields chosen for the match?
Any insight is greatly appreciated,
Lubomir
Dear Friends,
i think fuzzy lookup
COMPARES WHAT WE ARE MAPING THE COLUMNS WITH SPELLING (IT WILL REJECT ATLEAST 1 LETTER IS DIFFRENT IN ANY RECORD MAPPED COLUMN) EX: RAVI != REVI
what is fuzzy grouping ???? please explain

Or maybe it can't find something it's looking for to make my additional symetrical with everything else. This is from one of my businesslogic files. What causes Visual Studio to not allow me to add something here and have it behave like the other parameters/ I'm talking about ShortDesc. Visual studio inserted () and the Get instead of GET like all the others. It would not allow me to capitalize the "get". There has to be a reason for this. Currently my program is adding all of the fields except the ShortDesc to the table in my database. Does anyone have any thoughts as to why this is the case?
#Region "Pvt Members" Private _ArticleID As System.Int32 Private _UserID As System.Int32 Private _WebSiteID As System.Int32 Private _ArticleTitle As System.String Private _Author As System.String Private _ShortDesc As System.String Private _ArticleText As System.String Private _AnchorText As System.String Private _ShowInDirectory As System.Boolean Private _Active As System.Boolean Private _DateAdded As System.DateTime#End Region#Region "Properties" Public Property ArticleID As System.Int32 GET Return _ArticleID End Get Set(ByVal Value As System.Int32) _ArticleID= Value End Set End Property Public Property UserID As System.Int32 GET Return _UserID End Get Set(ByVal Value As System.Int32) _UserID= Value End Set End Property Public Property WebSiteID As System.Int32 GET Return _WebSiteID End Get Set(ByVal Value As System.Int32) _WebSiteID= Value End Set End Property Public Property ArticleTitle As System.String GET Return _ArticleTitle End Get Set(ByVal Value As System.String) _ArticleTitle= Value End Set End Property Public Property Author As System.String GET Return _Author End Get Set(ByVal Value As System.String) _Author= Value End Set End Property Public Property ShortDesc() As System.String Get Return _ShortDesc End Get Set(ByVal value As System.String) End Set End Property Public Property ArticleText As System.String GET Return _ArticleText End Get Set(ByVal Value As System.String) _ArticleText= Value End Set End Property Public Property AnchorText As System.String GET Return _AnchorText End Get Set(ByVal Value As System.String) _AnchorText= Value End Set End Property Public Property ShowInDirectory As System.Boolean GET Return _ShowInDirectory End Get Set(ByVal Value As System.Boolean) _ShowInDirectory= Value End Set End Property Public Property Active As System.Boolean GET Return _Active End Get Set(ByVal Value As System.Boolean) _Active= Value End Set End Property Public Property DateAdded As System.DateTime GET Return _DateAdded End Get Set(ByVal Value As System.DateTime) _DateAdded= Value End Set End Property #End Region
I've been looking into ways to accomplish a fuzzy search and SSIS makes that possible if I want to do a bulk import or something like it. But what it I just want to look stuff up at any given time not haveing to run the package?
Is it possible to expose the fuzzy lookup outside of SSIS to for example t-sql?
Here's an example:
I want to lookup the music artist "Notorious BIG" but in the database it is "Notorious B.I.G." if I use the SSIS fuzzy lookup I basically get what I'm looking for. But how would I call this from a web application? So then I tried Full text search but this doesn't really work out as well.
Will I have to re-write the logic that the fuzzy lookup uses to enable it to work? i.e. using Full Text Indexes and FreeTextTable, ContainsTable, SoundEx and the like to somewhat even come close to what the Fuzzy Lookup has?
Is there a built in capability in Sql server 2005 to do a search which can handle spelling errors. for eg.
We are doing a search for "hanovr" and our database contains "hanover" . In cases when there is a spelling error searching using LIKE,CONTAINS,FREETEXT are not giving me the results. Is there an out of the box solution for this problem.
Please Advice.
How do I do a fuzzy search? If I have a table of full names, I'd like the user to be able to do a search and find the record, "Charles Montgomery Burns" with "Monty Burns" or "Montgomry" (mispelling).
Every major web site does this kind of thing (Amazon, Google, etc).
Someone suggested SOUNDEX, but this really doesn't fit the bill. Misspellings often don't use the same sound signature as the originals. Plus, that doesn't handle multi-word searchable texts very well.
Others have suggested tries or suffix trees. If I went this route, wouldn't I have to preload all data out of the database and into this custom structure upon app startup? Is there any way around that? Also, this solution seems like it would require a lot of dev time (building a custom suffix tree with fuzzy lookup capabilities).
Is there a commonly known and acceptable solution to this?
(sorry, also posted to MySQL group; I'm using both databases so a solution in either would be satisfactory)
Hi,
I am using a fuzzy lookup to cleanse data from a sales line details table, during the import process. The sales order line details contains a filed called 'reference' and this is compared to a field called 'category' in another table.
Using data viewers to check through the cleansing process, I notice that the fuzzy lookup doesn't seem to match i.e.
tbl.salesline.reference = 'I3' -> tbl.sales.category ='I03'
the above is OK, but the lookup also returns the following
tbl.salesline.reference = 'I9' -> tbl.sales.category ='I01'
The value I9 doesnt exist, and is miskeyed by user entry, and should have been 'I99'. I would have expected the fuzzy lookup to pickup the I99 value as at least two of the chrs are matching, but no, it picks the first 'I*' in the table.
If I expand the fuzzy lookup to return more results, i.e. 5 per record, then it returns the first 5 results....I01, I02 I03 and so on.
Is there a way of improving the fuzzy lookup itself?
Hi all, I have been trying for a while now to clean some data that containes duplicate data using fuzzy grouping. I can get as far as identifying the duplicate data using fuzzy grouping but how do I get it out so I can insert non duplicate data a dimension table1?
What I am also stuck with is how do u set the data that isn't duplicate in the table1 as well, or is this done in the same step. Please help, deadlines are creeping in on me
Thanx for your time.
The enterprise edition of SQL server includes some advanced BI features, for example the fuzzy lookup feature of IS. If the IS package lives on an enterprise edition of SQL server and the database the package it is targeting lives on a standard edition of SQL server can the advanced features be used? Can you run a fuzzy look against a database on a standard edition of SQL server when th IS package lives on an enterprise edition of SQL server? THANKS!
Hi Friends,
Can some body briefly explain me what is the difference between fuzzy lookup and fuzzy grouping?
thanks and regards
A column in my database contains phrases such as "Extreme Golf: The Showdown" or "Welcome to Happy Land". I need to write a search engine so that users could type in phrases such as "Golf Extreme Showdown" or "Happy Land" and the correct, or closest matched results will be returned. I don't need variations of words, just phrase keyword match based search. I know I could do this by using multiple LIKE %% statements OR'd together, but this would be too performance intensive. So, I have heard I should use charindex somehow to achieve this in a stored procedeure. Does anyone have any clue how to solve this problem? Thanks!

Could someone please help!
Im doing a fuzzy lookup based on 3 fields (Surname/DOB/Gender). The only difference between the two sets of data is the case of the first letter of the Surname.
Reference table has "Stuart" Lookup has "stuart", I have set Fuzzy Lookup Input for Surname to Ignore Case but still it won't match.
The DOB/Gender are Exsactly the same.
Why does this not work? I there a work around?
Many Thanks, Deano

Fuzzy lookup seems to be causing some problems to me. It seems to work at times and doesn't at other times. It would work a couple of times fine and give me the desired results but then without changing anything in the dataflow or the data the next few times it would not run at all and fail the pre-execute of the.

Any ideas on how to get the Fuzzy Lookup to work
I managed to get fuzzy grouping working. The relevant output (_key_in and _key_out) are stored in a new table that is a copy of the old table + fuzzy grouping columns.
How do i get SSIS to store the _key_in and _key_out in the original table?
The new matching column _key_out refers to the new key: _key_in. How could i get SSIS translate that to a matching column that refers to my original key?

I have a Fuzzy Lookup in a Data Flow Task that is performing a simple text match based on a data view in SQL Server.
I keep obtaining the error below and I have no idea why. Is there a minimum number of rows required in the view in order for the lookup to work properly?
When I take the Store/Manage Index options off the lookup seems to work properly.
Thank you!

Is it possbile to have multiple fuzzy lookup within a data flow?
I need to have at least 3 fuzzy lookup in a data flow. Here're the conditions that I try to find match: 1=Zip&City, 2=Zip&State, 3=City&State. I've the first fuzzy lookup working fine. After that, I've a conditional split to get any unmatch, then use another fuzzy lookup for a second condition...at this point, I get the error saying "The package contains two objects with duplicate name of output column _Similarity..." I do not need to get the _Similarity and _Confidence, so is there a way to exclude them from returning in the output?
Any comments?
Thanks in advance.
Hi everyone,
Ive just started looking at the Fuzzy Lookup feature and i think i must be getting something fundamentally wrong. I have two tables - each contain different meta data representations for a set of potentially similar documents. The only chance i have of matching a document in table A to a document in table B is a common title field. However, manual input means that the titles may differ in both tables although they are potentially quite similar in most cases.
In the lookup i get to specify the output columns from table B (Reference) which is fine, but i don't seem to get to choose the columns from table A that i would also like to see. So my output shows me all the documents from table B that it thinks are similar to ones in table A...but not identifying which record it's similar to.
I initially thought that the "pass through" columns that i identified would appear in the output - but this does not seem to be the case.
I must be using it incorrectly, but i have no idea how to progress with this apart from creating a new source table (C) which is a full outer join of table A and B - and then also using table C as the reference table, but that seems madness.
any help would be appreciated - ta

Hi all
I've been doing some research and running some PoCs on using the Fuzzy Lookup Transformation (FLT) and had two questions:
1) When you choose to have a maximum of 1 output returned for each input, does FLT pick this output based on the best (highest) similarity and confidence scores or the first one it finds?
2) Why does FLT not support dynamically setting properties such as ReferenceTableName or MatchIndexName?
Any help or guidance with this is greatly appreciated.
Hi - we have been evaluating using Fuzzy Grouping and Lookup for maintaining our large list of customer records. Initial testing with Grouping on about 300K records went great but now with a larger sample of 7.3 million records we are running into problems. It doesn't appear to be system limitation - the index is built reasonably quickly and without errors but when it starts the matching we get these errors:
[Fuzzy Grouping Inner Data Flow : DTS.Pipeline] Error: The ProcessInput method on component "Fuzzy Lookup" (86) failed with error code 0x8000FFFF. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.

[Fuzzy Grouping Inner Data Flow : DTS.Pipeline] Error: Thread "SourceThread0" has exited with error code 0xC0047038.
One thing we did find is that our test server didn't have SP1 installed and that seemed to help a lot (we were getting buffer errors prior to SP1). One other note - the desination table is populated with all the data but no scoring has been applied to it.
Does anyone have any ideas what could be causing this?
Thanks!

Hello,
I have created a project to do de-dupification of addresses.
I understand that Fuzzy Grouping will take less time if it has lesser data volume to process.
My source feed file is sometimes huge. So I am splitting the input into multiple branches based on
the first letter of the city. There are 7 branches in the process.

But in reality they are processing one after the other.
Is there anyway to make them execute in parallel?

Hi there,
Quick Background: I have an SSIS package that reads data from a flat file then runs it through a Fuzzy Grouping component. The result of this Fuzzy Group is put into a SQL server 2005 table.
Question: Over time, the flat file will be adding new records (some that should be added to existing groups) and so I'll need to update my Fuzzy Group table to include these new records. Is there anyway to simply add these new records to the existing Fuzzy Group without changing all of the _key_out values? If I completely regenerate the Fuzzy Group table that will potentially give me different _key_out values correct?
Does this make sense?
Any help would be greatly appreciated!
Good day.
I'd like to add "fuzzy search" functionality to my application.
"Fuzzy search" in this topic means selecting (from DB table) rows, which have "fuzzy search" coefficient (calculated using etalon string) not less some_predefined_const. Fuzzy search coefficient calculating algorithm can be various.
So with etalon string "Margaret" "fuzzy search" can find "Nargaret", "Margoret", "Margret" etc.
IMHO time to develop, test and tune code must be quite long. I prefer to buy such "fuzzy search" component.
Does anybody know where can I get such component - server version (SQL 2005) or client version (.NET)?
How much can such component cost?
Thanks.
I created a fuzzy transformation with an input table and a reference table. When I go to the Columns tab, there are no available input or lookup columns displayed. But if I select a different reference table, sometimes it works.
Are there any specific properties a reference table must have in order for columns to show up?
Thanks,
Tom
