Hi, Iam a newbee to Stanbol. I want to use Stanbol to be able to extract meaningful data from different unstructured text. Fields of interest are based on my custom vocabulary. Data in the unstructured text will keep changing and cannot be indexed upfront
Have followed the instructions on this link - http://stanbol.apache.org/docs/trunk/customvocabulary.html >From reading the link under stand I would need to follow only the keyword >linking approach. Did following 1. Created a Yard Site implementation 2. Uploaded by basic vocabulary into this using the curl command 3. Created an EntityHub linking engine 4. Create an enhancement chain with following components * langdetect ( required , LanguageDetectionEnhancementEngine) * opennlp-sentence ( required , OpenNlpSentenceDetectionEngine) * opennlp-token ( required , OpenNlpTokenizerEngine) * opennlp-pos ( required , OpenNlpPosTaggingEngine) * opennlp-chunker ( required , OpenNlpChunkingEngine) * opennlp-ner ( required , NamedEntityExtractionEnhancementEngine) * CustentityhubExtraction ( required , EntityLinkingEngine) 5. When I run query I do not see entities from vocabulary getting identified Note : Currently my vocabulary is very simple. More entities will be added later. It is an Ontology which has only 1 entity Person Person in turn has following properties - Name, City, DateOfBirth I think I have gone wrong is some configuration parameter. I had doubts in following : 1. In the Entity Hub linking engine a. What do we enter in the fields used for dereferencing i. Do we delete the default mappings provided b. What do we enter in the Type mappings c. In processed languages do we need to enter any special parameters 2. In the Managed Site yard site what do we enter for field mappings a. I have entered person:name > dbp:Person:birthName , not sure if this is correct b. Do we need to retain the default mappings 3. In the Solr Yard configuration I have not defined any Solr cor. Gone with default core / create on initialization. Is this ok Please confirm if the steps followed are correct. What do I need to make the custom vocabulary work. Have spent most of last week on this but unable to get this working. Request your help for same Thanks a lot, Arthi Please do not print this email unless it is absolutely necessary.
