txt here is a set of lines from your example with trailing ... removed;
here are the first two:
,.2{.txt
+----------------------------------------------------------------------+
|bell 0.0264 -0.2927 -0.0254 -0.1034 0.1672 -0.0440 -0.0019 0.1210 |
+----------------------------------------------------------------------+
|bell_tower -0.1252 -0.1233 0.1351 0.1897 0.0242 0.0014 0.1942 -0.0237 |
+----------------------------------------------------------------------+
This separates words from numerica vectors of arbitrary length:
( i.&' ' ({.;0 ". }.)] ) every txt
+----------+-----------------------------------------------------------+
|bell |0.0264 _0.2927 _0.0254 _0.1034 0.1672 _0.044 _0.0019 0.121 |

It should be easy enough to split off the first column as a word-list,
and the second as a vector of vectors.
OK?

I read in a text file of word vectors using fread. The format looks like
this:
bell 0.0264 -0.2927 -0.0254 -0.1034 0.1672 -0.0440 -0.0019 0.1210 ...
bell_tower -0.1252 -0.1233 0.1351 0.1897 0.0242 0.0014 0.1942 -0.0237 ...
belt 0.1332 0.0142 -0.1208 -0.0574 0.1451 -0.0731 -0.1293 0.0855 ...
belfast 0.1190 -0.0440 -0.0254 -0.2090 0.2144 0.0348 -0.1467 0.1256 ...
Everything is literal text.
The basic layout for each line is:
word(s) (could contain multiple words separated by underscores)
space
number (positive or negative) in text format
space
number (positive or negative) in text format
space
...... repeat for 300 numbers (in text)
the last number is followed by a line feed for the next line
I need to:
1. Convert all the the high minuses (-) to J's low minus (_)
2. Extract the word(s) up to the first space into a separate array (words)
3. Convert the text numbers into a 2D array of ? x 300 floating point
numbers
I know how to do #1 (string replace), and #3 (".) once I get rid of the
words,
but I don't know how to strip out the initial word on each line and put
them in a separate array. Any help is appreciated.
