I'm using Uima Ruta 2.5.0 Version. In this, Symbols like Γ,Δ were coming under CW .Why its Happening?
Input
Γ
Δ
The CW annotation like the other TokenSeed annotations is created by a JFlex lexer. The rule for CW is [:uppercase:][:lowercase:]* whereas [:uppercase:] is defined by the Unicode properties \p{Uppercase}. Both of your example symbols are greek uppercase letters.

From the Ruta Documentation, A WORDTABLE is simply a comma-separated file (.csv), which actually uses semicolons for separation of the entries. I need to change the the seperator option.Because Some text contains semicolon, So its coming in seperate column.
I've changed the Seperator Option, I received an error message.
How can I solve this issue.
Example:
I really like beef, with mushroom sauce; pasta, with Alfredo sauce; and salad, with French dressing.;0
Think before you speak.;1
We had students from Lima, Peru; Santiago, Chile; and Caracas, Venezuela.;2
Up to the current UIMA Ruta version (2.6.1), changing the separator for the csv tables is not supported. Unfortunately, quoting is also not supprted.

I am trying to match some multi-word tokens using UIMA RUTA 2.6.0. And there are some phrases that are partially equal to each other, e. g. in the same file I has following entries: "includes the", "include the", "in this", "in the".
There is next piece of text in my input file: "1. "Agents or employees" includes the directors...". Obviously, there is a "includes the" match, but if other above 3 entries are present in wordlist then no match will be found. Moreover, the ordering of those entries in wordlist does not depend on matching success: it always fails.
And this issue occurs not only in single file. So, the question: how can I fix it? May be some settings of RUTA annotator?
Whitespaces in the wordlist can lead to missed matches. If the whitespaces are not important, set the configuration parameter 'dictRemoveWS' to true.

Can I segment the letters of a word using Uima Ruta?
Ex.
1.(WHO)
2.(APIAs)
Script:
DECLARE NEW;
BLOCK (foreach)CAP{}
{
W{REGEXP(".")->MARK(NEW)};
}
Yes, this is achieved with simple regex rules in UIMA Ruta:
DECLARE Char;
CAP->{"."->Char;};
You cannot use normal rules for this because you need to match on something smaller than RutaBasic. The only option is to use regexp rules which operate directly on the text instead of on annotations. You should of course be very careful since this can lead to really many annotations.
Some explanation for the somewhat compact rule: CAP->{"."->Char;};
CAP // the only rule element of the rule: match on each CAP annotation
->{// indicates that inlined rules follow that are applied in the context of the matched annotation.
"." // a regular expression matching on each character
-> Char // the "action" of the regex rule: create an annotation of the type Char for each match of the regex
;}; // end of regex rule, end of inlined rules, end of actual rule
Summarizing, the rule iterates over all CAP annotations, applies a regular expression on each iterated covered text and creates annotations for the matches.
You can of course also use a BLOCK instead of an inlined rule.

How can we annotate an unicode character in uima ruta:
For Example: I want to mark this text(Paris: Éditions Robert Laffont).So I used the following rule.
DECLARE CITY;
CW COLON CW+{->MARK(CITY,1,3)};
But the text covered upto Paris: Ã. Is there any way to solve this problem. Awaiting for the answer.Thanks in advance.
Its all about he definition of the lexer which creates the token class annotations of ruta (W, CW, SPECIAL ...).
The rule CW COLON CW+{->MARK(CITY,1,1)}; creates an annotation of the type CITY for the text span Paris regardless of the unicode character.
The last rule element CW+ matches on à since this is annotated with a CW, but stops there since ‰ is not a CW but a SPECIAL.
There are different ways to avoid this problem. My advice would be that you should rely on a different type of annotation for your rules. The job of the lexer annotations of ruta is to create minimal annotations. They do not define tokens in general.
You could maybe use something like this (or use an actual tokenizer for better performance):
DECLARE CITY;
DECLARE Token;
RETAINTYPE(SPACE);
(W (SPECIAL? W)*){-> Token};
RETAINTYPE;
Token COLON Token+{->MARK(CITY,1,1)};

I used emacs with haskell mode, now I am trying to use the IDE in eclipse with eclipseFP plug-in support, the problem is that eclipse is unable to recognize (nor input) greek characters! So how can I make eclipse to recognize and input greek characters?
The workspace, and each file have an encoding setting - change it to UTF-8 (type "encoding" in the properties dialog)
That said, you should not put greek characters into your code. Use english, and externalize i18nized values.
