Personal data is
constantly collected, either voluntarily by users in emails, social
media interactions, multimedia objects, calendar items, contacts, etc.,
or passively by various applications such as GPS of mobile devices,
transactions, quantified self sensors, etc. The processing of personal
data is complicated by the fact that such data is typically stored in
silos with different terminologies/ontologies, formats and access
protocoles. Users are more and more loosing control over their data;
they are sometimes not even aware of the data collected about them and
how it is used.
We discuss the new
concept of Personal Information Management Systems (PIMS for short) that
allows each user to be in a position to manage his/her personal
information. Some applications are run directly by the PIMS, so are
under direct control of the user. Others are in separate systems, that
are willing to share with the PIMS the data they collect about that
particular user. In that later case, the PIMS is a system for
distributed data management. We argue that the time has come for PIMS
even though the approach requires a sharp turn from previous models
based on the monetisation of personal data. We consider research issues
raised by PIMS, either new or that acquire a new flavor in a PIMS
context.
We also present works
on the integration of user’s data from different sources (such as email
messages, calendar, contacts, and location history) into a PIMS. The
PIMS we consider is a Knowledge Base System based on Semantic Web
standards, notably RDF and schema.org. Some of the knowledge is
“episodical” (typically related to spatio-temporal events) and some is
“semantic” (knowledge that holds irrelative to any such event). Of
particular interest is the cross enrichment of these two kinds of
knowledge based on the alignment of concepts, e.g., enrichment between a
calendar and a geographical map using the location history. The goal is
to enable users via the PIMS to query and perform analytics over their
personal information within and across different dimensions.
