Description

---

OCEAN-AI is an open-source library consisting of a set of algorithms for intellectual analysis of human behavior based on multimodal data for automatic personality traits (PT) assessment. The library evaluates five PT: Openness to experience, Conscientiousness, Extraversion, Agreeableness, Non-Neuroticism.

---

OCEAN-AI includes three main algorithms:

1. Audio Information Analysis Algorithm (AIA).
2. Video Information Analysis Algorithm (VIA).
3. Text Information Analysis Algorithm (TIA).
4. Multimodal Information Fusion Algorithm (MIF).

The AIA, VIA and TIA algorithms implement the functions of strong artificial intelligence (AI) in terms of complexing acoustic, visual and linguistic features built on different principles (hand-crafted and deep features), i.e. these algorithms implement the approaches of composite (hybrid) AI. The necessary pre-processing of audio, video and text information, the calculation of visual, acoustic and linguistic features and the output of predictions of personality traits based on them are carried out in the algorithms.

The MIF algorithm is a combination of three information analysis algorithms (AIA, VIA and TIA). This algorithm performs feature-level fusion obtained by the AIA, VIA and TIA algorithms.

In addition to the main task - unimodal and multimodal personality traits assessment, the features implemented in OCEAN-AI will allow researchers to solve other problems of analyzing human behavior, for example, affective state recognition.

To install the library, you should refer to the Installation and Update.

To work with audio information, you should refer to the Audio information processing.

To work with video information, you should refer to the Video information processing.

To work with text information, you should refer to the Text information processing.

To work with multimodal information, you should refer to the Multimodal information processing.

The library solves practical tasks:

1. Ranking of potential candidates by professional responsibilities.
2. Predicting consumer preferences for industrial goods.
3. Forming effective work teams.

OCEAN-AI uses the latest open-source libraries for audio, video and text processing: librosa, openSMILE, openCV, mediapipe, transformers.

OCEAN-AI is written in the python programming language. Neural network models are implemented and trained using an open-source library code PyTorch.

Research data

The OCEAN-AI library was tested on two corpora:

1. The publicly available and large-scale First Impressions V2 corpus.
2. On the first publicly available Russian-language Multimodal Personality Traits Assessment (MuPTA) corpus.
