“…Nascent academic research further supports reminiscing when utilizing computer-mediated environments. People collect digital mementos, read their past Facebook posts and reflect on their memories in human-computer interfaces (Bowena and Petrelli, 2011;Kalnikait and Whittaker, 2011;Zhao et al, 2013;Tejaswi Peesapati et al, 2010).…”

“…The SenseCam has been used in various studies [9], [17][18][19][20][21][22][23][24] participants. For 3 days, the users then captured any pictures and audio narratives about significant people, places and objects in their lives [8]. This study illustrated that HDMs are important for reflection and that people are interested in reflecting upon their digital artefacts.…”

“…For example, in relation to YouTube, traffic from mobile devices tripled in 2011 and over 4 billion hours of video are watched each month, with more than 20% of global views coming from such devices [7]. This shift in ubiquitously capturing and sharing content has led to people creating extensive digital collections and reflection of those items has become an active part of people's lives [8]. Taking the concept of capturing personal content one step further, the practise of 'lifelogging' refers to the process of automatically recording aspects of one's life in digital form [9].…”

The abundance of mobile and sensing devices, within our environment, has led to a society in which any object, embedded with sensors, is capable of providing us with information. A human digital memory, created with the data from these pervasive devices, produces a more dynamic and data rich memory.Information such as how you felt, where you were and the context of the environment can be established. This paper presents the DigMem system, which utilizes distributed mobile services, linked data and machine learning to create such memories. Along with the design of the system, a prototype has also been developed, and two case studies have been undertaken, which successfully creates memories. As well as demonstrating how memories are created; a key concern in human digital memory research relates to the amount of data that is generated, and stored. In particular, searching this set of big data is a key challenge.In response to this, the paper evaluates the use of machine learning algorithms, as an alternative to SPARQL, and treats searching as a classification problem. In particular, supervised machine learning algorithms are used to find information in semantic annotations, based on probabilistic reasoning. Our approach produces good results with 100% sensitivity, 93% specificity, 93% positive predicted value, 100% negative predicted value, and an overall accuracy of 97%.

It is considered to be the most basic and important operation of the brain, with very few cognitive processes (recognition, language, planning, etc.) being able to operate effectively without a contribution from it [1]. They are a significant part of our existence that can be shared anywhere and at any time. Reminiscing, over past experiences, is a substantial part of our lives.It is a practice that has been performed over thousands of years and is what makes us who we are. However, losing the ability to recollect memories is not only disadvantageous, but can prove quite detrimental, particularly to many older people [2]. Nevertheless, recent advances in technology can alleviate this problem, to a certain extent. As technology advances, computing devices have now taken a more central role in our lives. They have shifted in reliance from just being seen as "glorified calculators" [3], to devices that are capable of capturing and storing our entire lives. As such, this shift has resulted in the area of creating and managing human digital memories, being declared a grand challenge in computing researchIn today's society, the proliferation of "smart" mobile devices is becoming more abundant.Currently, 81.6 million mobile subscriptions are held in the UK [5]. By 2016, Cisco predicts that...

Abstract-Living in the digital age has resulted in a data rich society where the ability to log every moment of our lives is now possible. This chronicle is known as a human digital memory and is a heterogeneous record of our lives, which grows alongside its human counterpart. Managing a lifetime of data results in these sets of big data growing to enormous proportions; as these records increase in size the problem of effectively managing them becomes more difficult. This paper explores the challenges of searching such big data sets of human digital memory data and posits a new approach that treats the searching of human digital memory data as a machine learning problem.
