Data Description

LSC2019 uses the same data as LSC2018, which consists of 27 days of data from one active lifelogger. The dataset is based on the NTCIR-13 Lifelog dataset, but it is enhanced and compacted to represent one month of detailed user activity. The dataset is composed of a number of files; the core image dataset, the associated metadata on a per-minute basis, the information access dataset on a per-minute basis and the provided visual concept data for each image. Additionally we provide a csv-format activity annotation for each minute in the collection. Each link is username/password protected and each zip file is additionally password protected. Each participating organisation will receive the passwords to access the data.


Multimedia

  • Narrative Clip 2. Set at 45 second interval.. From breakfast to sleep. This is about 1,500 images per day. There is an accompanying output of a concept detector to assist teams in building a search engine for the data.
  • Music listing history (see an example of music listening history here)

Biometrics
  • Biometrics 24x7 (heart rate, galvanic skin response, calorie burn, steps)
  • Blood Pressure daily, in the morning after preparing (but before eating) breakfast and before exercising
  • Blood Sugar levels every morning after waking up, before eating.


Human Activity
  • Semantic locations visited
  • Physical activities
  • Daily mood, according to Thayers 2 dimensional model of mood
  • Diet log (manual logging of photos of food).


Computer Usage (as document vectors on a per-minute basis)
  • Computer input via keyboard and information consumed on the computer via ASR of on-screen activity on a per-minute basis. This data is filtered using a blacklist, anonymised and then stemmed using an English language stemmer. Each minute is represented by a sorted document vector.

LSC2019 Data Release Forms

Participants are required to sign two forms to access the datasets, an organisational agreement form for your organisation (signed by the research team leader) and an individual agreement form for each member of the research team that will access the data. The organisation agreement form should be sent to the LSC organisers (lsc@computing.dcu.ie) in PDF format. The individual agreement form must be signed by all researchers who will use the data and kept by the organisation on file. It should not be sent to the organisers, unless requested at a later date.

  1. Organisation Agreement form: to be signed by the organisation to which the participants belong. This form must be signed and sent by email to LSC organisers (lsc@computing.dcu.ie).
  2. Individual Agreement form: to be signed by each individual researcher wishing to use the LSC data collection. This form must be filed by the participating organisation, but it does not need to be sent to the organisers.

Upon completion of this process, the participants will be sent a unique username and password to access the dataset.



LSC 2019 Development Topics


  • A set of six development topics will be made available to assist teams in developing their lifelog search engines.
  • Associated with these development topics, there will be an evaluation harness that allows teams to input image IDs and receive a score depending on submission accuracy, which will be operational on 15 February 2019.
