Java Exception: Issues when using the Lexicon-Grammar graph

[Jorge Baptista]

Dear All,

Using Unitex 3.0, I am trying to intersect a table with 2 columns and 1800+ lines, consisting of a list of nouns and a list or verbs (in both cases these are <lemmas>), with a reference graph in order to produce a general resulting graph that will enable me to look for all the {V,N} combinations in a corpus.
In the noun column, there is only one lemma per line; in the verb column, there can be one or multiple lemmas, separated by the “+” (plus) sign.

The Lexicon-Grammar compilation goes smoothly, and I can compile each subfile individually and I can also apply each file separately to the text (everything works fine).

BUT I am unable to compile the result-graph (resulting from the intersection of the reference graph and the table with 1800+ lines) and there is a  “ERROR”message being displayed. The fst2 is void (0 bytes). Also, the Locate Pattern, can not compile this  result-graph, very lijkely for the same reason.

The console indicates:

"/Applications/Unitex3.0/App/UnitexToolLogger" Grf2Fst2 "/Users/Jorge.Baptista/unitex/Portuguese (Brazil)/Dela/Fazer/res-graph.grf" -y "--alphabet=/Users/Jorge.Baptista/unitex/Portuguese (Brazil)/Alphabet.txt"


The information provided in the Java Exception window is shown below.

Could you please help me identify the problem and eventually find a solution for it?
Thank you a lot.

Yours truly
JB

Dear Jorge,

If the table has more than 1800 lines, the main generated graph probably invokes more than 1800 subgraphs. Maybe this goes beyond some threshold. You could check this hypothesis by repeating the experiment with only a sample of the table, say, 25 lines.
Yours

Eric

Dear Eric, 

Thank for your swift reply! 

Yes, it worked fine: I split the table in 3+ parts of 500 lines each, and the system compiles the result graph and can then apply it to the text.

I did the same with 1k and 1,5k lines.

Apparently, there is limit to the size of the result-graph or the number of subgraphs.

Thank you for the suggestion, I will try to keep in mind the threshold

Regards

Jorge Baptista

Hi Jorge,

If you have then a lot of graphs for your grammar, you can use a cascade to parse a text with all the graphs.

Best regards,

Denis Maurel
