CAMEO-coded LEVANT file for AFP -- 15 April 2015

This research was supported in part by the National Science Foundation Political Science 
Program grant SES-1004414 and numerous earlier NSF grants.

This is a very extensive revision of the earlier Levant AFP file, which had a number of gaps
due to missing dates in the Lexis-Nexis files. These have now been confirmed, and the missing
dates filled in with Reuters stories.

Specific additions:

790415-910505: All Reuters -- 6 May 1991 is where the AFP coverage begins

920121-920401

920707-920913

920919-921007

921009-921118

950929-951103

980626-980902

In addition, a couple of gaps that had occurred in some of the earlier sequences
due to dropped files, but where Lexis-Nexis in fact had coverage, were filled in
from downloads.

Also there are a few apparent gaps of about a week each at various times in March-April 1993
and April-May 1994: these are simply due to very sparse coverage during that period but do 
not correspond to actual Lexis-Nexis coverage gaps.

Implications for any analysis: Reuters and AFP are not necessarily comparable
in terms of the density or distribution of events, so if you are doing an
analysis that is looking for cut-points, anything occurring in the vicinity
of these dates should be regarded as a likely artifact. And, obviously, you
might consider replacing all of these with missing values, again depending
on the analysis. For the work we are doing, a more or less continuous time
series seemed preferable.

UPDATE: 19 December 2011
The period Feb 2009 to Nov 2011 was appended to the previously coded data, using the 
previous dictionaries but the current version of TABARI, which corrected a couple of 
bug located during ICEWS.  

UPDATE: 15 April 2015
Records for the period 1 Dec 2011 to 31 Mar 2015 were coded using the same dictionaries
and TABARI version 0.7.6b1 and appended to the earlier files.

Files:

AFPLE.201503.evt.txt -- event data, all events [269,203 events, including internal DOC documentation]
AFPLE.201503.evt.filt.txt -- events remaining after "OneADay" filter removed duplicates [246,382 events]
