The Information Retrieval and Extraction Workflow allows you to set up some tasks in @Note, including the Journal Retrieval (mandatory) and Journal Crawling, Corpus creation, NER and RE Processes (optionally).

To run the workflow, you must select the option Workflow -> Information Retrieval and Extraction on the Menu Bar.

Select Steps

The next step is to determine the tasks that will be executed by the workflow. The Pubmed Search is mandatory but Corpus Creation and NER and RE processes can also be applied to this Corpus in subsequent operations. After selecting the tasks, press Next to continue.

Corpus Type

Abstract : : Only publications with abstracts will be considered.

If you have selected only the task of corpus creation, the processing of your data will start after clicking ok. When this process finishes, you can see the results in the Workflow_Report

Otherwise, if other steps are included, press next to proceed to NER configuration.

Select NER Process

(Optional)

The next step is configuration a NER Process. Using combo box the must select NER process that servers your efforts.

NER - Based in Lexical Resources

You can select a NER Based in lexical resources. The configuration have two panel Basics an Advanced:

Basic Option

Here you must select one or many dictionaries to run NER.

Advance Option

Expert User can configure some advance options. This options are based in NER - Lexical Resource NER - Lexical Resources

If you just select NER PRocess, workflows process starts after clinking ok button. When process over you can see results in Workflow_Report

Otherwise press next button to proceed to RE configuration.

Select RE Process

(Optional)

The next step is configuration a REProcess. Using combo box the must select Re process that servers your efforts.

RE Based in POS-Tagging

You can select a RE Based Natural Language processing. The configuration have two panel Basics an Advanced.

Basic Option

Here you must select the relation model

Advance Option

Expert User can configure some advance options. This options are based in RE Relation Extraction

Processing

As the process proceeds the user can see the status of activity looking to progress bar

Workflow Report

As a result of the process appears a Workflow_report
