Can clustering or association help me improve the quality of my data?

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :

I have a bunch of attributes that get tossed into a model.  Attribute P comes from a human selecting something from a drop-down list, and is thought to be wrong 30% of the time.  When the user chooses the wrong P then all the aggregations that happen downstream are wrong, and this in turn affects the model I'm trying to build.  I have several thousand distinct values of P.

Is there a way that I can build a model & query that will somehow flag the values for P that seem to be wrong and suggest the correct value for P ?

Extracting Association Rules from Data Mining Model

Hi I have succesfully created a Data Mining Model using the Association Model. I have deployed and processed it. I need to extract all the rules that is generated by the model. I know that you normally query the model using DMX prediction queries, but in this case I need to extract the rules to a separate table for further processing. I have tried the following approaches unsuccessfully: 1. Linked server in MSSQL Management Studio. DMX query using OpenQuery. The DMX query looks like this: SELECT FLATTENED NODE_CAPTION, NODE_SUPPORT, NODE_PROBABILITY, MSOLAP_NODE_SCORE FROM DataMiningModel.CONTENT WHERE NODE_TYPE = 8   On small models this method works. On larger models with many rules I receive an exception: "XML for Analysis parser: The XML for Analysis request timed out" before it was completed This always happens after 70min. I might have missed a timeout option? 2. Using SSIS to run the same DMX query as above. The method is presented here: http://www.sqlservercentral.com/articles/MDX/64697/ This method works on small models. On larger models that did not work with method 1, it return rules. The number of rules returned is sometimes different for the same package run multiple times. For the largest models it simply returns 0 rules. I suspect that the same XML Parser error happens under the hood of SSIS. I'm currently stuck, and need some inp

Question about quality of data

Hello, Thanks for the help on the last question.  We have looked at several open source offers in the field of data integration. We are now wanting data quality software to complete our data integration program.  Do packages exist to suit our needs? Would you know of innovative data quality programs? Thanks to all!

BDC, external list with many-to-many Association, how to input data

Hi, I have built a BDC with VS2010 and Sharepoint Enterprise as target platform. It is basically a technical evaluation about many-to-many Associations in external content types. Its has 2 entities which are Person and Ticket and should reflect a data model where persons can work on multiple tickets and tickets can also involve multiple persons. For linking those 2 entities I have a link table which can be read via the "Navigators" and be modified via the "Associator/Disassociator". I made the model completely with the VS2010 bdcm designer and as far as I know its good. (Its a "foreign key less" association, the identifiers are UInt32.) Now my question is how do I actually use those manipulators, or at least show data and related data. With 1-to-n relations Sharepoint did render an interface for handling the relation for me, but with a keyless n-to-m relation I dont get any interface for connecting the entities at all. Then I tried to make this via Infopath, but as far as I can tell, you cant use a 2nd datasource there with external List. (And it seems to be supposed to be this way.)

How to improve the speed of data transfer in WCF service using basicHttpBinding

Surrogate vs Natural Primary Keys - Data Modeling Mistake 2 of 10

In case you're new to the series I've compiled a list of ten data modeling mistakes that I see over and over that I'm tackling one by one. I'll be speaking about these topics at the upcoming IASA conference in October, so I'm hoping to generate some discussion to at least confirm I have well founded arguments.

The last post in this series Referential Integrity was probably less controversial than this one. After all, who can argue against enforcing referential integrity? But as obvious as surrogate keys may be to some, there is a good deal of diversity of opinion as evidenced by the fact that people continue to not use them.

Editing the Data in a GridView

In addition to deleting a GridView's underlying data, another common need is to allow end users to edit the data displayed in a GridView. With ASP.NET 1.x's DataGrid control, editing the data is certainly possible, but requires creating three event handlers and writing a dozen or so lines of code. With the GridView and ASP.NET 2.0, it is possible to create an editable GridView without writing a single line of code! All of the necessary functionality is encapsulated within the GridView.

The GridView allows editing on a row-by-row basis. An editable GridView contains an additional column with an Edit button in each row. When the end user clicks on an Edit button that row becomes editable, causing the Edit button to change to Update and Cancel buttons and the other columns to become TextBoxes. The end user can then update one or more column values and click Update to save their changes.

Using ASP.NET 3.5's ListView and DataPager Controls: Displaying Data with the ListView

Prior to ASP.NET 3.5, developers who needed to display a set of records could choose between the GridView, DataList, and Repeater controls. The GridView provides rich data features, but has a very boxy layout; the DataList and Repeater allow for a more flexible layout, but lack the "point and click" data features found in the GridView, DetailsView, and FormView controls. The ListView bridges the gap between layout flexibility and built-in data features.

This article, the first in a series of articles on the ListView and DataPager controls, looks at the ListView's many available templates and illustrates how to display data. Read on to learn more!

Dynamic Data Templates in GridView ASP.NET 3.5

At a high level, Dynamic Data Templates can be seen as a system to very quickly build up a User Interface linked with the relevant data model, immediately enabling you to perform CRUD operations (Create, Read, Update, Delete) on the database using the specified data source. They provide a powerful method for building up these kinds of applications, and I'm going to focus on an overview of what Dynamic Data Templates actually are, and a few ways of customizing them to suit industry needs.

MS SQL Server: Search All Tables, Columns & Rows For Data or Keyword Query

If you need to search your entire database for specific data, this query will come in handy.

So when a client needs a custom report or some sort of custom development using Great Plains, most of the time I will have to track down the data in the system by running this query and find the table(s) it is in.

Displaying Data using ASP.NET 2.0 Repeater and C#

This tutorial will show you how to display data using the .NET Repeater Control, ASP.NET 2.0 and C#.NET

The Repeater control is a powerful tool and is easy to use.

First, you will need to import the System.Data.SqlClient namespace.

MVC architecture in ASP.Net using C# and Microsoft Data Access Application block

The Model-View-Controller (MVC) pattern separates the modeling of the domain, the presentation, and the actions based on user input into three separate classes [Burbeck92]:

Model. The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller).

View. The view manages the display of information.

Controller. The controller interprets the mouse and keyboard inputs from the user, informing the model and/or the view to change as appropriate.
