Whether sequencing is possible-uima ruta - uima

Question

Whether sequencing is possible in uima ruta.
For example:
Input File:
some text
Fig 1.1
Table 1.1
Fig 1.2
some text
Pic 1.2
Table 1.2
some text
Table 1.3
Pic 1.3
some text
Fig 1.4
some text
Table 1.4
some text
Table 1.5
Fig 1.6
Box 1.1
Fig 1.5
How can I find the missing Figure(Fig 1.3)

Answer 1

Here's an example how it could be done with UIMA Ruta 2.5.0.
Input text:
some text
Fig 1.1
some text
Pic 1.2
some text
Pic 1.3
some text
Fig 1.4
some text
Rule script:
DECLARE FigureInd;
DECLARE FigureMention (INT chapter, INT section);
ACTION FM(INT chap, INT sect) = CREATE(FigureMention, "chapter" = chap, "section" = sect);
"Fig"-> FigureInd;
INT c, s;
(FigureInd NUM{PARSE(c)} PERIOD NUM{PARSE(s)}){-> FM(c,s)};
DECLARE FigMissing;
f1:FigureMention #{-> FigMissing} f2:FigureMention
{f1.chapter == f2.chapter, f1.section < (f2.section - 1)};
INT pc, ps;
f:FigureMention{-> pc=f.chapter, ps=f.section}
FigMissing->{
(ANY #NUM{PARSE(c)} PERIOD NUM{PARSE(s)}){c==pc,s==ps+1-> FM(c,s), pc=c, ps=s};
};
Created FigureMention annotations:
Fig 1.1
Pic 1.2
Pic 1.3
Fig 1.4
A solution for UIMA Ruta 2.4.0 is very similar but does not allow direct usage of features of annotation label expressions. The values of these features need to be stored in additional variables. And one need to apply the boolean check after the setter of the variables. Here a solution for UIMA Ruta 2.4.0:
DECLARE FigureInd;
DECLARE FigureMention (INT chapter, INT section);
ACTION FM(INT chap, INT sect) = CREATE(FigureMention, "chapter" = chap, "section" = sect);
"Fig"-> FigureInd;
INT c, s;
(FigureInd NUM{PARSE(c)} PERIOD NUM{PARSE(s)}){-> FM(c,s)};
DECLARE FigMissing;
INT c1,c2,s1,s2;
(FigureMention<-{FigureMention{-> ASSIGN(c1, FigureMention.chapter), ASSIGN(s1, FigureMention.section)};}
#{-> FigMissing}
FigureMention<-{FigureMention{-> ASSIGN(c2, FigureMention.chapter), ASSIGN(s2, FigureMention.section)};})
{c1 == (c2), s1 < (s2 - 1)};
INT pc, ps;
f:FigureMention{-> pc=FigureMention.chapter, ps=FigureMention.section}
FigMissing->{
(ANY #NUM{PARSE(c)} PERIOD NUM{PARSE(s)}){c==(pc),s==(ps+1)-> FM(c,s), pc=c, ps=s};
};

Answer 2

The following script creates an annotation with min and max values of the missing figures in UIMA Ruta 2.4.0:
DECLARE FigureInd;
DECLARE FigureMention (INT chapter, INT section);
DECLARE FigureMissing (INT minChapter, INT minSection, INT maxChapter, INT maxSection);
ACTION Mention(INT chap, INT sect) = CREATE(FigureMention, "chapter" = chap, "section" = sect);
ACTION Missing(INT minc, INT mins, INT maxc, INT maxs) = CREATE(FigureMissing, "minChapter" = minc, "minSection" = mins, "maxChapter" = maxc, "maxSection" = maxs);
"Fig"-> FigureInd;
INT c, s;
(FigureInd NUM{PARSE(c)} PERIOD NUM{PARSE(s)}){-> Mention(c,s)};
DECLARE FigMissing;
INT c1,c2,s1,s2;
(FigureMention<-{FigureMention{-> ASSIGN(c1, FigureMention.chapter), ASSIGN(s1, FigureMention.section)};}
#{-> Missing(c1,s1+1,c2,s2-1)}
FigureMention<-{FigureMention{-> ASSIGN(c2, FigureMention.chapter), ASSIGN(s2, FigureMention.section)};})
{c1 == (c2), s1 < (s2 - 1)};
In UIMA Ruta, there is no loop over boolean expressions (like while), only over existing annotations. This makes it more complicated to create separate annotations for each missing Fig on the same offset. However, it can be done with a recursive BLOCK. The script of the answer rather creates one annotation defining a range of missing figures.
For the text exmaple of the question, two FigureMissing annotations are created:
FigureMissing
- begin: 41
- end: 112
- minChapter: 1
- minSection: 3
- maxChapter: 1
- maxSection: 3
FigureMissing
- begin: 123
- end: 165
- minChapter: 1
- minSection: 5
- maxChapter: 1
- maxSection: 5
If the second FigureMissing should not be created, an additional rule could remove it again depending on the existing FigureMentions. This would of course be much simpler if separate FirgureMssing annotations would have been created, e.g., with a BLOCK.
