Deaf people who learned to sign in their childhood

0

Informants, i.e. people registered for the needs of the body, are just deaf people who learned to sign in their childhood. They come from different parts of Poland, so their way of signing allows you to better understand and describe the dialectal diversity of this language. Their signatures are recorded in a special studio equipped with digital cameras, computers, data storage discs, lighting equipment, etc.

Collecting data for the corpus is an extremely complex and time-consuming process. Whistleblower statements must be spontaneous and natural, but must be skillfully evoked. To this end, a wide range of activities are used, such as the summary of a movie seen or the description of an illustration. The recording session lasts several hours, during which only sign language is used: in addition to informants, the deaf also include moderators and even cameramen.

However, the collection of video data is only the first step to an in-depth study of PJM. It is equally important to develop the collected material, that is, to divide the recorded statements into individual sign signs and their detailed analysis using special software (made available to PLM researchers by the team of the German Sign Language Institute in Hamburg which collaborates with them, that is, one of the most important research centers on communication in the world. Deaf).

This process, called corpus annotation by linguists, will take several years because it requires many hours of work. For example, a one-minute video is recorded by an experienced researcher for at least an hour.  The work of PLM researchers has already brought the first tangible results. This year, based on data from the corpus, the first ever PJM dictionary was created that records the actual use of this language.
