Call for Participation in TRECVID 2018


February 2018 - November 2018

Conducted by the National Institute of Standards and Technology (NIST)
with additional funding from other US government agencies

I n t r o d u c t i o n:

The TREC Video Retrieval Evaluation series ( promotes
progress in content-based analysis of and retrieval from digital video
via open, metrics-based evaluation. TRECVID is a laboratory-style
evaluation that attempts to model real world situations or significant
component tasks involved in such situations. In it's 18th annual evaluation
cycle TRECVID will evaluate participating systems on 6 different video
analysis and retrieval tasks using various types of real world datasets.

D a t a:

In TRECVID 2018 NIST will use at least the following data sets:

      * IACC.3

      The IACC.3 is a new dataset introduced in 2016 of approximately 4600 Internet Archive
      videos (144 GB, 600 h) with Creative Commons licenses in MPEG-4/H.264
      format with duration ranging from 6.5 min to 9.5 min and a mean duration
      of almost 7.8 min. Most videos will have some metadata provided by the
      donor available e.g., title, keywords, and description.

      * IACC.2.A, IACC.2.B, and IACC.2.C

      Three datasets - totally approximately 7300 Internet Archive
      videos (144GB, 600 hours) with Creative Commons licenses in
      MPEG-4/H.264 format with duration ranging from 10 seconds to 6.4
      minutes and a mean duration of almost 5 minutes. Most videos will have
      some metadata provided by the donor available e.g., title, keywords,
      and description

      * IACC.1.A, IACC.1.B, and IACC.1.C

      Three datasets - totaling approximately 8000 Internet Archive videos
      (160GB, 600 hours) with Creative Commons licenses in MPEG-4/H.264
      format with duration between 10s and 3.5 minutes. Most videos will
      have some metadata provided by the donor available e.g., title,
      keywords, and description


      Approximately 3200 Internet Archive videos (50GB, 200 hours)
      with Creative Commons licenses in MPEG-4/H.264 with durations
      between 3.6 and 4.1 minutes. Most videos will have some metadata
      provided by the donor available e.g., title, keywords, and

      * BBC EastEnders

      Approximately 244 video files (totally 300GB, 464 hours) with
      associated metadata, each containing a week's worth of BBC EastEnders
      programs in MPEG-4/H.264 format.

      * Twitter Vine videos
      Approximately 50,000 video clips URLs have been collected by NIST 
      from the public Twitter stream of Vine videos. Only a subset of at
      least 2,000 videos will be used with their human annotated text descriptions.

      * Twitter and Flickr images and videos

      Approximately 188000 images and over 44000 videos were collected from
      Twitter social media events and over 26500 images from Flickr. These data 
      will be used to support the social-media video storytelling linking task.

      * Gatwick and i-LIDS MCT airport surveillance video

      The data consist of about 150 hours obtained from airport
      surveillance video data (courtesy of the UK Home Office). The
      Linguistic Data Consortium has provided event annotations for
      the entire corpus. The corpus was divided into development and
      evaluation subsets. Annotations for 2008 development and test
      sets are available.

T a s k s:

In TRECVID 2018 NIST will evaluate systems on the following tasks
using the [data] indicated:

    * AVS: Ad-hoc Video Search (automatic, manually-assisted, relevance feedback) [IACC.3]

      A new Ad-hoc search task started in TRECVID 2016 and will continue in 2018 
      to model the end user search use-case, who is looking for segments of video containing 
      persons, objects, activities, locations, etc. and combinations of the 
      former. Given about 30 multimedia topics created at NIST, return 
      for each topic all the shots which meet the video need expressed by it,
      ranked in order of confidence. Although all evaluated submissions will be
      for automatic runs, Interactive systems will have the opportunity to
      participate in the Video Browser Showdown (VBS) in 2019 using 
      the same testing data (IACC.3).

    * ActEV: Activities in Extended Video (ActEv)
      The ActEV evaluation seeks to evaluate robust automatic activity detection algorithms 
      for a multi-camera streaming video environment. ActEV is an extension of the annual TRECVID 
      Surveillance Event Detection (SED) evaluation by adding a large collection of multi-camera 
      video data, both of simple and complex activities. ActEV will address activity detection for 
      both forensic applications and for real-time alerting.

    * INS: Instance search (interactive, automatic) [BBB EastEnders] 

      An important need in many situations involving video collections
      (archive video search/reuse, personal video organization/search,
      surveillance, law enforcement, protection of brand/logo use) is to
      find more video segments of a certain specific person, object,
      or place, given a visual example. In 2016 new query type was tested 
      by asking systems to retrieve specific persons in specific locations. 
      The same query type will continue in 2018 but with new testing topics.
      A set of master locations with various video examples will be given and 
      each topic will include few examples (image and video) of a person and 
      ask systems to find that person in one of the known locations.

    * SMKBP: Streaming Multimedia Knowledge Base Population

      Given streams of text, speech, images, video, and their associated metadata, 
      from a variety of genres, both formal (e.g.,news) and informal (e.g., social media, blogs), 
      systems are asked to analyze each incoming information item (~100k items in total) 
      and produce a set of structured representations (knowledge elements) about events, 
      sub-events or actions, entities, relations, locations, time, and sentiments (beliefs) 
      that are observable in that information item given an ontology/schema and zero or more 
      background (context) information.

      This is a joint task with the Text Analysis Conference (TAC) run by NIST.

    * LNK: Social-media video storytelling linking [Twitter and Flickr images/videos]
      The social-media video storytelling linking task seeks to advance the area of 
      visual summarization, with collaborative videos, images and texts available from 
      professional media and social-media users. The challenges in creating such visual 
      timelines are various: alignment of videos and images through sound or timestamps 
      to smooth transitions or remove duplicates, detection of video intervals of high 
      interest, caption generation for a group of pictures, among others. The goal of the 
      task is to illustrate a news story with social-media content. Starting from a news 
      story topic and a stream of social-media video and images, the goal is to link a 
      story-segment to image and video material, while also preserving a good flow of the 
      whole visual story.

    * VTT: Video to Text Description [Twitter Vine videos]

      Automatic annotation of videos using natural language text descriptions 
      has been a long-standing goal of computer vision. The task involves 
      understanding of many concepts such as objects, actions, scenes, person-object 
      relations, temporal order of events and many others. In recent years there has 
      been major advances in computer vision techniques which enabled researchers to 
      start practically to work on solving such problem. A lot of use case application 
      scenarios can greatly benefit from such technology such as video summarization, 
      facilitating the search and browsing of video archives using such descriptions, 
      describing videos to the blind, etc.
      Given a set of Vine videos URLs and number of reference sets of text descriptions, 
      systems are asked to work and submit results for two subtasks. A "Matching and Ranking" 
      subtask to return for each video URL a ranked list of the most likely text description 
      that correspond (was annotated) to the video from each of the reference sets. And a 
      "Description Generation" subtask to automatically generate for each video URL a text 
      description (1 sentence). 

In addition to the data, TRECVID will provide uniform scoring
procedures, and a forum for organizations interested in comparing
their approaches and results.

Participants will be encouraged to share resources and intermediate
system outputs to lower entry barriers and enable analysis of various
components' contributions and interactions.

* You are invited to participate in TRECVID 2018 *

The evaluation is defined by the Guidelines. A draft version is
available: and
details will be worked out starting in February based in part on input
from the participants.

You should read the guidelines carefully before applying to participate in one or more tasks: 

P l e a s e   n o t e:
1) Dissemination of TRECVID work and results other than in the
(publicly available) conference proceedings is welcomed, but the
conditions of participation specifically preclude any advertising claims based on TRECVID results.

2) All system output and results submitted to NIST are published in
the Proceedings or on the public portions of TRECVID web site archive.

3) The workshop is open only to participating groups that submit
results for at least one task and to selected government personnel
from sponsoring agencies and data donors.

4) Each participating group is required to submit before the November
workshop a notebook paper describing their experiments and results.
This is true even for groups who may not be able to attend the

5) It is the responsibility of each team contact to make sure that
information distributed via the call for participation and the email list is disseminated to all team members with
a need to know. This includes information about deadlines and
restrictions on use of data.

6) By applying to participate you indicate your acceptance of the
above conditions and obligations.

There is a tentative schedule for the tasks included in the Guidelines
webpage: Schedule

W o r k s h o p   f o r m a t

Plans are for a 2 1/2 day workshop at NIST
in Gaithersburg, Maryland - just outside Washington, DC. Confirmation
and details will be provided to participants as soon as available.

The TRECVID workshop is used as a forum both for presentation of
results (including failure analyses and system comparisons), and for
more lengthy system presentations describing retrieval techniques
used, experiments run using the data, and other issues of interest to
researchers in information retrieval. As there is a limited amount of
time for these presentations, the evaluation coordinators and NIST
will determine which groups are asked to speak and which groups will
present in a poster session. Groups that are interested in having a
speaking slot during the workshop will be asked to submit a short
abstract before the workshop describing the experiments they
performed. Speakers will be selected based on these abstracts.

H o w   t o   r e s p o n d   t o   t h i s   c a l l

Organizations wishing to participate in TRECVID 2018 must respond
to this call for participation by submitting an on-line application by
2. April.  Only ONE APPLICATION PER TEAM please, regardless of how
many organizations the team comprises.

*PLEASE* only apply if you are able and fully intend to complete the
work for at least one task. Taking the data but not submitting any
runs threatens the continued operation of the workshop and the
availability of data for the entire community.

Here is the application URL: 

You will receive an immediate automatic response when your application
is received. NIST will respond with more detail to all applications submitted
before the end of February.  At that point you'll be
given the active participant's userid and password, be subscribed to
the tv18.list email discussion list, and can participate in finalizing
the guidelines as well as sign up to get the data, which is controlled
by separate passwords.
