A very good place to start searching about edit distances between words and
some related stuff can be found on Peter Norvigs site at:

It's not the JPA one. It's the meta-model work-in-progress for the
neo4j project.
It so happens I was using neo4j-1.1-snapshot with an older meta-model
implementation.
I pulled the meta-model-0.9 snapshot which seems to work.fine.
But the above question is still valid in a generic sense..

You might also want to look into Freebase. Here's a Clojure client you
can use to query their data. http://github.com/rnewman/clj-mql

This is a hard problem.
If you go by degrees and shades of synonymity, it can (and has been)
done manually - see Visual Thesaurus (http://
www.visualthesaurus.com/).
But for grouping based on the same semantic topics - that's pretty
difficult. You could do it based on co-location in a corpus, but
Looks like a bug to me. Fixed it locally with the change below, after
the Java implementations where atVal(x) delegates to atVal(x,null).

I want to write a clojure program that searches for similarities of
words in the english language and places them in a graph, where the
distance between nodes indicates their similarity. I don't mean
syntactical similarity. Related contextual meaning is closer to the

For instance: "fish" a

thanks! that worked. the cast to int makes sense is since the jvm will
convert the byte value to an int for the & computation

Hi all,
Todays' project involved modelling what happens if an infected flea
enters a burrow of gerbils. The biology is as follows: fleas feed
daily on gerbils, and drop off after every meal, only to climb on one
of the gerbils again. There is a small chance that a feeding flee

If I use lein swank and have (slime-setup '(slime-repl)) in my .emacs,
the repl doesn't work (try (+ 1 2)). Changing this to (slime-setup

SBCL, CCL64, KAWA and QiII work fine with (slime-setup '(slime-repl)).

Hi Bill,
Are your looking for something as simple as this:
(defrecord Foo [x])
(defn load-a-record-at-runtime
"Loads a record value from a file"

(Foo. (slurp f)))
Or is there some subtlety here?

Hey folks,
It was suggested to me in IRC to check here before filing a bug
report. I've noticed that the mappish object returned by clojure.core/
bean will throw an NPE if you try to access a missing key. Since
normal maps don't do this, and I can't think of any reason you would
want that behavior
Thanks. That does look clearer.

Yes, there is easier variant:

Maybe SPOJ treat clojure as script language. In fact, though clojure
is quite fast, loading the clojure.jar library takes a bit of time.
And SPOJ count the class loading time into the running time. If the
Judge Machine is similar to ideone.com, maybe the clojure.jar loading
time is about 0.6~0.7s.
The confusion over type and instance was a sloppy example. Sorry.
But in your solution I'm confused by one thing. You create and
instance of Foo in the let and then assoc the new value of List1 to
it.
This has two problems. One is that the loaded data is not
permanent. The other is that th

You mention one use case of the repl, but I think that's just one part
of a typical workflow. Say you decide to write a function, you start
half way and then you realize that you need to group pairs of items in
a vector and then turn these pairs into a vector of maps. Oh, but
what order are the a
