Valossa AI September 21 Update: New Video Topic Analysis with IAB 2.2 and Sensitive Categories

Our Latest Release Brings IAB Tech Lab Content Taxonomy 2.2 Topic Classification – Adds Sensitive Topics analysis

Right on the heels of the IAB Taxonomy 2.1 classification release last month, Valossa AI has evolved again to detect an even broader set of video topics based on IAB Tech Lab Content Taxonomy v2.2, including 11 sensitivity categories to support brand safety and content appropriateness for advertising.

IAB content topics are being analyzed contextually inside the video modalities of speech, audio, visuals, and OCR. At the document level, Valossa AI summarises the most prominent categories that describe the entire video. Over 500 categories have been trained into the system.

As an example, we have broadened the NLP-based understanding of sensitive, inappropriate, or unwanted language use across speech and visual text to support a broad range of content styles. The improvement has also facilitated adding new topic categories such as “crime”, “death” and “hateful language”. The topics are complex even for modern content analysis, and we will keep working on the new categories in future updates.

Let’s look into an example of sensitive topics extraction from a collage of movie clips depicting death: Valossa AI identifies narrative topics about death from speech, visuals, and OCR. This is useful in contextual advertising scenarios where videos focusing on graphic depictions of death should be avoided.

Also, with the powerful IAB 2.2 Content Taxonomy classification feature, Valossa AI provides proprietary categories that have been expanded to support over 60 different video topic types.

Note! Future Changes in Valossa Metadata Format.

The following “explicit_content” detection types will be deprecated in Valossa Core Metadata and removed completely in the next update planned for October 2021:

  • explicit_content.transcript.offensive
  • explicit_content.ocr.offensive

The same detections can now be found in the following detection types tagged with Valossa tag category “bad_language”:

  • audio.keyword.compliance
  • transcript.keyword.compliance
  • visual.text_region.keyword.compliance (OCR)

As always, these new features keep broadening our audio-visual intelligence abilities and are immediately available to our customers through Valossa AI subscriptions.
