RemembranceAgents

Because serendipity is too important to be left to chance…

From the web page:

Remembrance Agents are a set of applications that watch over a user’s shoulder and suggest information relevant to the current situation. While query-based memory aids help with direct recall, remembrance agents are an augmented associative memory. For example, the word-processor version of the RA continuously updates a list of documents relevant to what’s being typed or read in an emacs buffer. These suggested documents can be any text files that might be relevant to what you are currently writing or reading. They might be old emails related to the mail you are currently reading, or abstracts from papers and newspaper articles that discuss the topic of your writing.

We are experimenting with remembrance agents in word processors, web browsers, and on wearable computers. The word-processor version works in Emacs and XEmacs.

What it does

The RA consists of two parts: One part is an indexing program which you should probably run in the background once a day. It is written in C and understands lots of document formats such as HTML, mail folders, etc. This index is used in the second part: An Emacs add-on which looks at the text around point and searches for similar documents in the index. A little window at the bottom of the frame lists the best matches and allows you to move there with a click.

Discussion

I find remem fascinating and use it often when I write. The novel Angel Deep

is an example of remem’s use. Here is the load defun I use

;;;  remem mode
(defun rharris-load-remem ()
  "Load remembrance agent mode"
  (interactive)
  (setq load-path (cons "/usr/local/share/emacs/remem" load-path))
  (load "remem.el")
  (setq remem-prog-dir "/usr/local/bin")
  (setq remem-database-dir "/usr/local/share/remem/db")
; scopes take form: (DIRN NUM-LINES UPDATE-TIME QUERY-RANGE) where:
;   DIRN is the subdirectory of remem-database-dir with the desired database
;   NUM-LINES is the number of lines that you want the scope to show (initially)
;   UPDATE-TIME is the time between scope updates (in seconds)
;   QUERY-RANGE number of words around your cursor that you want the scope to query on
  (setq remem-scopes-list '(("kjv" 2 10 500)
                            ("hdt" 2 10 500)))
)

Then I use a data defining fn for each of the novel’s voices.

(defun rharris-remem-uncas ()
"Angel Deep: Uncas's voice"
(interactive)
(setq remem-scopes-list '(("bard_mov" 2 10 500)
                          ("hdt" 2 10 500)
                          ("lotm" 2 10 500)))
			  )

It has been a while since I used it. I ended up not finding it useful, perhaps there wasn’t really that much personal data around, thus not many related documents. Perhaps this is for people like RichardStallman who gets 400 mails a day or so… – AlexSchroeder

I like RemembranceAgents. I index my blog and my mail during my shutdown sequence. I wish I had a faster computer, though… – SachaChua
