Sentiment analysis of insurance firms

Hello readers,

In this segment, the responses of people on twitter handles of insurance firms have been analysed.
Firms under consideration were:

MetLife @metlife
Northwestern Mutual @NM_News
Prudential of America @PrudentialNews
New York Life @NewYorkLife
Lincoln National @lincolnfingroup
MassMutual @massmutual
John Hancock @JohnHancockUSA
State Farm  @StateFarm
Guardian Life Insurance Co. @guardianlife

The approach methodology and R packages used can be found from my other posts on this blog.
The results of analysis are as under:

Sl. No.	Insurance firms	Total tweets returned from handle	very.pos.count	very.neg.count	very.tot	score (%)
1	Guardian Life Insurance Co.	65	9	0	9	100
8	Prudential of America	34	5	0	5	100
6	New York Life	227	46	1	47	98
9	State Farm	1000	86	14	100	86
2	John Hancock	79	12	3	15	80
3	Lincoln National	56	4	1	5	80
4	MassMutual	496	11	4	15	73
7	Northwestern Mutual	368	78	60	138	57
5	MetLife	1000	52	180	232	22
Legend:
Any posts/ tweets with score greater than +2 is very positive and lesser than -2 is very negative.
We can ignore twitter handles that returned less than 100 tweets.
Score= 100*very.pos.count/very.tot

New York Life has appeared a very clear leader though its handle returned only 227 tweets.
State Farm and MetLife returned 1000 tweets, but it was surprising to see MetLife come last.

Thanks.
