Q: How fast is the sentiment analysis plugin?
A: In our own test scenario the plugin can analyse a group of 100 000 messages (~30,4 MB) in 32 seconds, which is about 3125 messages per second.
This is with PHP 7 and a single process. The pickmybrain search engine supports multiprocessing and the performance scales up pretty well!
Q: Do you ever update the sentiment analysis plugin?
A: Yes! We will provide updates for each language pack from time to time. You don't pay anything for these updates.
Q: Do I have to use the sentiment analysis library with the Pickmybrain search engine?
A: Absolutely not! You can use it also as a stand-alone library for document scoring and classification.
# include the pmbsentiment library
$lang = "fi"; # finnish language
$lang = "en"; # english language
$pmbsentiment = new PMBSentiment($lang);
# provide some text for analysis
$scores = $pmbsentiment->score("Broccoli is delicious and good for your health.");
# the $scores variable will now include an associative array containing
# the sentiment scores for each class (pos, neu, neg)
