Hi Bhagwat, The ctakes-temporal module has the components needed to generate tlinks. Using trunk, the following can be added to the end of the default clinical pipeline piper file (or a copy):
load TemporalSubPipe The TemporalSubPipe.piper file contains the following setup to create events, times, time relative to document writing (doctimerel) and tlinks: /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // Commands and parameters to create a default temporal processing sub-pipeline. This is not a full pipeline. // 'Generic' Events. Use addDescription and let the EventAnnotator set itself up with defaults. addDescription EventAnnotator // Times. There aren't default models, so set specifically add BackwardsTimeAnnotator classifierJarPath=/org/apache/ctakes/temporal/ae/timeannotator/model.jar // DocTimeRel: the relation bin for Events to the Document Creation Time. add DocTimeRelAnnotator classifierJarPath=/org/apache/ctakes/temporal/ae/doctimerel/model.jar // Event - Time binary relations. add EventTimeRelationAnnotator classifierJarPath=/org/apache/ctakes/temporal/ae/eventtime/model.jar // Event - Event binary relations. add EventEventRelationAnnotator classifierJarPath=/org/apache/ctakes/temporal/ae/eventevent/model.jar /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// To see the code used for tlink detection, search ctakes for the EventTimeRelationAnnotator.java and EventEventRelationAnnotator.java classes. All piper "add" commands are followed by a class name. I have a piper file that I use for testing a 'full' ctakes pipeline: /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// // Advanced Tokenization: Regex sectionization, BIO Sentence Detector (lumper), Paragraphs, Lists load AdvancedTokenizerPipeline // Always need these ... add ContextDependentTokenizerAnnotator add POSTagger // Chunkers load ChunkerSubPipe // Default fast dictionary lookup set minimumSpan=2 load DictionarySubPipe // Cleartk Entity Attributes (negation, uncertainty, etc.) load AttributeCleartkSubPipe // Entity Relations (degree/severity, anatomical location) load RelationSubPipe // Temporal (event, time, dtr, tlink) load TemporalSubPipe // Coreferences (e.g. patient = he) load CorefSubPipe // Html output add pretty.html.HtmlTextWriter // XMI output writeXmis /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// Sean -----Original Message----- From: Bhagwat Posane [mailto:bhagwat.pos...@gmail.com] Sent: Wednesday, November 08, 2017 2:41 AM To: dev@ctakes.apache.org Subject: Re: source code of user installation of cTakes. [EXTERNAL] [SUSPICIOUS] Hi Sean and Tim, Could you please provide your valuable inputs for below questions: I am interested in finding the context of clinical notes like if any procedure is happened or not. I think TLINKS values on web API maybe helpful to get the required result, not sure though. Please confirm I am not able to find the code to generate TLINKS, could you please help me locate the code.
