Subject RE: SideEffectAnnotator issues
Date Wed, 16 Dec 2015 20:20:20 GMT
The side effects annotator is really old (circa 2010). It was initially developed for psychiatric
drugs and their side effects. Description is in this publication: http://jamia.oxfordjournals.org/content/18/Supplement_1/i144.abstract

I am not quite sure how well the annotator works now... We are working on other methods for
side effect extraction and are likely to publish them in spring of 2016.

I hope this helps.

Subject: SideEffectAnnotator issues

Hi,

I'm hoping for some more insights into using the side effect annotator.

As per Pie Chen's suggestion I've added the side effect annotator to the default AggregatePlaintextFastUMLSProcessor.
The xml changes are shown below.

Initially I was getting 'URI is not hierarchical' errors. After some searching I thought this
might be due to a missing dictionary file and added sideEffect_dictionary.txt at 'apache-ctakes-3.2.2\resources\org\apache\ctakes\sideeffect\lookup'.

This stopped the URI errors. I put some dummy content in the dictionary (shown below; using
the full content from here didn't help either - https://urldefense.proofpoint.com/v2/url?u=https-3A__svn.apache.org_repos_asf_ctakes_trunk_ctakes-2Dside-2Deffect-2Dres_src_main_resources_org_apache_ctakes_sideeffect_lookup_sideEffect-5Fdictionary.txt&d=BQICaQ&c=qS4goWBT7poplM69zy_3xhKwEW14JZMSdioCoppxeFU&r=SeLHlpmrGNnJ9mI2WCgf_wwQk9zL4aIrVmfBoSi-j0kfEcrO4yRGmRCJNAr-rCmP&m=cq3dLDFzFSH1DRnh30N1vwFozDMinGQA_mbzqpzsuXA&s=wosr80zHuzsbhDmk3ABFQB5BJckImO8OO9S1nrLQWMU&e=
).

Now as per the log files, I'm getting null pointer exceptions within sideEffectAnnotator.java
- at 2 different locations as shown below. 
Getting an exception is dependent on the text analysed:
'Seen today. On tamoxifen 20 mg daily which caused headaches.' causes an exception.
'Seen today. On tamoxifen 20 mg daily which caused something.' does not (of course there is
no clinical finding in the second text).

Given that others are using the side effect annotator, I'm guessing this is some kind of issue
with my configuration/dictionary and would appreciate any advice.

I'm running the latest version of cTakes 'as is'.

Thanks in advance.
