This was the strength of the Hypertext system I built around VistA years ago. We had an entity file which helped to manage the documents and the entities that they were attached to. My basic model was used to build the library system of Belgium. I built the hypertext system for the US Public Health Service. Unfortunately, even though I delivered on time and had functionality that allowed for the assembly of "studies" which became collections of documents in the library. It allowed for the researcher to annotate documents (like writing in the margins) and the annotations become separate documents in the library with links to the document that spawned that annotation. This was a lot of text that was all cross-indexed in withing the document, but also between documents. There was a predicate logic engine I was working on which would help locate the use of phrases anywhere in the text and evaluate the value of the document to the search criteria by the propinquityof the words of the phrases within the body of text. The closer the words of the phrases in the text, the higher the score for the order of the documents.
Unfortunately, the US Publich Health Service didn't continue with the project. It was a snap grant. ----- Original Message ----- From: "Jim Self" <[EMAIL PROTECTED]> To: <hardhats-members@lists.sourceforge.net> Sent: Tuesday, June 20, 2006 3:34 PM Subject: Re: [Hardhats-members] VHA eyes open-source replacement for VistA > This is also one of the historical strengths of VMACS and it is something that I could > help bring to VistA with M2Web. > > > Bhaskar wrote: > >What's interesting about all this is that searches through unstructured > >text are increasingly common.
