>for given NewsID how can get the most related newsID
Define 'most related', preferable with some mockup 'before and after' data.  

Where I'm from you could be cousins multiple ways.

Are you looking for NewsIDs with NewsTags having same WordWeight as given NewsID?
If there are multiple NewsTags in the given NewsID, what should be the criteria to pick the other relevant NewsID?

insert in releated table

Hello,

Here is a query to identify the related news. I am selecting the news tag id and the word weights for the given news id and related news id. You may pick only the columns you want finally.
Insert into @RelatedNewsIDs (MainNewsID, NewsSYSTagsID, MainWordWeight, RelatedNewsID, RelatedWordWeight)
Select Distinct Main.NewsID, Main.NewsSYSTagsID, Main.WordWeight, Related.NewsID, Related.WordWeight
From NewsSYSNewsTags Main, NewsSYSNewsTags Related
Where Related.NewsID <> Main.NewsID
And Related.NewsSYSTagsID  = Main.NewsSYSTagsID 
And Related.WordWeight >= Main.WordWeight - Main.WordWeight * .05 
And Related.WordWeight <= Main.WordWeight + Main.WordWeight * .05 
And Main.NewsId = 1001 --Your news ID to search

Open in new window
