Missing table during Model Building for wikipedia extraction #4

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Install Wikipedia Miner english
2. Comment lines 272-280 (topic extraction)
3. Uncomment lines 262-270 (model build)
3. Execute maui.main.Examples indexing_with_wikipedia

Expect to build a model.
Throw exceptions. Cf. below.
It doesn't build the model. If I launch an extraction after, it doesn't work : 
-- Reading instance
-- Converting instance for document 0018
Warning! This documents does not contain valid keyphrases
---- Extracting candidates... 
---- Disambiguating candidates...
54 candidates 
0 positive; 54 negative instances
-- Processing document: 0018
-- Keyphrases and feature values:

What version of the product are you using? On what operating system?
Maui 1.0 on Windows XP JDK 1.6

Here's the exception:

java.sql.SQLException: Table 'wiki_db_en.anchor_occurance_casefolder'

I fixed the problem replacing line 1557:
   anchor = new Anchor(form, textProcessor, wikipedia.getDatabase());
by:
   anchor = new Anchor(form, null, wikipedia.getDatabase());
Don't know if that "TextProcessor" was important or not...

In WikipediaMiner different kind of tables with pre-processed article titles 
can be generated. When document 
phrases are mapped to Wikipedia articles they can be case folded, stemmed etc.

Hi,
What is the best table to use for keyword extraction with the newly uploaded 
MauiTopicExtractor model.

Thank you
Jason

In Wikipedia-miner, while creating and populating the tables using the 
loadData() method in WikipediaDatabase.java, also uncomment the following line:
wikipedia.getDatabase().prepareForTextProcessor(new CaseFolder()) ;

This will create the tables anchor_CaseFolder and anchor_occurance_CaseFolder 
and then Maui will build the model correctly.
