Idio, the content analytics platform which is sold in to publishers, has acquired thrudigital, a social media development agency.
Once you send out the content, analytics let you see the number of impressions, locations, unique views and how long viewers stayed on the site.
The content analytic text mining approach using adjusted probabilities provided a balance of sensitivity and specificity.
Two techniques were used to examine the sensitivity and specificity of the content analytic text mining generated 'SPV Tags'.
Specificity of the content analytic text mining approach was somewhat lower than for the basic keyword method (0.95 vs 0.99), and this is reflected in the lower PPV.
Table 1 summarises the results of the text based search techniques (keyword and index) and Table 2 summarises the results of the content analytic text mining techniques.
Using the content analytic text mining approach with the binary classification (i.e. belonging to the 'Work SPV Tag' or the 'Other Activity SPV Tag'), 31,194 potential 'Work Activity' cases were identified, with 17,299 of these true cases and 13,894 false positives.
The basic keyword search detected 58% of cases (Specificity 0.99), an index search detected 62% of cases (Specificity 0.87), and the content analytic text mining (using adjusted probabilities) approach detected 77% of cases (Specificity 0.95).
In comparison, the content analytic approach with adjusted probability, had a higher sensitivity at 0.77 and had the second highest PPV (at 0.65), though this represented 8,699 false positives and 16,424 true cases.
Using the content analytic text mining approach with adjusted probability classification, 25,123 potential 'Work Activity' cases were classified, with 16,424 of these true cases and 8,699 false positives (See Table 2).
Hardware acceleration through specialization has received renewed interest in recent years; such acceleration has generally been implemented using two chips, with the image signal processing (ISP) part being performed by a DSP, a GPU or an FPGA and the video content analytics (VCA) part being executed by a processor.
