Key Facts 🔑






This is synthetic data! Generated using proprietary algorithms - no privacy violations!

Conversations are classified following the taxonomy for privacy-sensitive robotics by Rueben et al. (2017).

The data was manually labeled by an expert.





Dataset Structure




Data Instances




The provided data format is .jsonl, the JSON Lines text format, also called newline-delimited JSON. An example entry looks as follows.




{ "text": "CW: Have you ever been to Italy? CR: Oh, yes... many years ago.", "taxonomy": 0, "category": 0, "affected_speaker": 1, "language": "en", "locale": "US", "data_type": 1, "uid": 16, "split": "train" }




Data Fields




The data fields are:






text: a string feature. The abbreviaton of the speakers refer to the care worker (CW) and the care recipient (CR).

taxonomy: a classification label, with possible values including informational (0), invasion (1), collection (2), processing (3), dissemination (4), physical (5), personal-space (6), territoriality (7), intrusion (8), obtrusion (9), contamination (10), modesty (11), psychological (12), interrogation (13), psychological-distance (14), social (15), association (16), crowding-isolation (17), public-gaze (18), solitude (19), intimacy (20), anonymity (21), reserve (22). The taxonomy is derived from Rueben et al. (2017). The classifications were manually labeled by an expert.

category: a classification label, with possible values including personal-information (0), family (1), health (2), thoughts (3), values (4), acquaintance (5), appointment (6). The privacy category affected in the conversation. The classifications were manually labeled by an expert.

affected_speaker: a classification label, with possible values including care-worker (0), care-recipient (1), other (2), both (3). The speaker whose privacy is impacted during the conversation. The classifications were manually labeled by an expert.

language: a string feature. Language code as defined by ISO 639.

locale: a string feature. Regional code as defined by ISO 3166-1 alpha-2.

data_type: a string a classification label, with possible values including real (0), synthetic (1).

uid: a int64 feature. A unique identifier within the dataset.

split: a string feature. Either train, validation or test.





Dataset Splits




The dataset has 2 subsets:






split: with a total of 95 examples split into train, validation and test (70%-15%-15%)

unsplit: with a total of 95 examples in a single train split

Dataset Creation




Curation Rationale




Recording audio of care workers and residents during care interactions, which includes partial and full body washing, giving of medication, as well as wound care, is a highly privacy-sensitive use case. Therefore, a dataset is created, which includes privacy-sensitive parts of conversations, synthesized from real-world data. This dataset serves as a basis for fine-tuning a local LLM to highlight and classify privacy-sensitive sections of transcripts created in care interactions, to further mask them to protect privacy.




Source Data




Initial Data Collection




The intial data was collected in the project Caring Robots of TU Wien in cooperation with Caritas Wien. One project track aims to facilitate Large Languge Models (LLM) to support documentation of care workers, with LLM-generated summaries of audio recordings of interactions between care workers and care home residents. The initial data are the transcriptions of those care interactions.




Data Processing




The transcriptions were thoroughly reviewed, and sections containing privacy-sensitive information were identified and marked using qualitative data analysis software by two experts. Subsequently, the sections were translated from German to U.S. English using the locally executed LLM icky/translate. In the next step, another llama3.1:70b was used locally to synthesize the conversation segments. This process involved generating similar, yet distinct and new, conversations that are not linked to the original data. The dataset was split using the train_test_split function from the Scikit-learn library.




Who are the source language producers?




Care workers and care recipients in a residential care home in a German-speaking country.




Annotations




Annotation process




Each entry in the synthetic data was read by an expert and labeled according to the various classifications.




Who are the annotators?




Reinhard Grabler and Michael Starzinger




Personal and Sensitive Information




As this is completely synthetic data, there is no personal or sensitive information in this data set.




Considerations for Using the Data




Social Impact of Dataset




The ability to automatically detect privacy-sensitive parts of a conversation is a versatile use case that extends beyond care interactions. This technology has broad applications, such as in human-robot interactions and other scenarios involving active speech processing. Its implementation can significantly enhance privacy across these diverse applications.




Discussion of Biases




The source data comes from a residential care home in a German-speaking country. The classification was also carried out by an expert in a German-speaking country. Therefore, no cultural differences in the perception of privacy are reflected in this data set.




Other Known Limitations




The collection of original data for synthesis is a highly time-consuming process. Recordings are conducted by care workers amidst their already demanding day-to-day care responsibilities. Additionally, complete transcripts must be manually reviewed to identify and redact privacy-sensitive information. Consequently, the current volume of data is limited. Ongoing efforts aim to expand the master dataset as additional phases of the study are conducted. Furthermore, research is underway to explore and develop improved methods for generating high-quality synthetic data tailored to this use case.
