Temporal Image Caption Retrieval Competition
=====================================

Retrieve a caption for a picture from a historical newspaper.

# Task Description

## Introduction

Multimodal models, especially combining vision and text, are gaining great recognition. A recent example is the image generation model, DALL·E 2 [1]. One such multimodal challenge is Text-Image retrieval, which is to retrieve an image for a text query or retrieve a text for a given image. In this challenge, we introduce a task in the Text-Image retrieval setup, additionally extending the modalities with temporal data.

Language models rarely utilize any input information except for text. E.g additional data could be a text domain, document timestamp, website URL, or other metadata information. However, models trained solely on text data may be limited in usage. Additional temporal information is useful when factual knowledge is required, but the facts change over time (answering the question: “Who is the president of the U.S.A”, “Who was the president of the U.S.A at 1950”), or language semantic changes (word “gay” meaning shifted from “cheerful” to referring homosexuality).

The presented task is based on the Chronicling America [2] and Challenging America [3] projects. Chronicling America is an open database of over 16 million pages of digitized historic American newspapers covering 274 years. Challenging America is a set of temporal challenges built from the Chronicling America dataset.

## Task Definition

The objective is, given a picture from a newspaper and the newspaper's publication daily date, to retrieve a picture caption from a given caption set. Always, exactly one caption is relevant.

## Sample data

**INPUT**:

Image:

[<img src="https://git.wmi.amu.edu.pl/kubapok/cnlps-ticrc/raw/branch/master/sample-picture.png">](https://git.wmi.amu.edu.pl/kubapok/cnlps-ticrc)


Date timestamp: `19280111`

Set of all possible captions: `example caption1`, `example caption2`, `MUTT AND JEFF–  IT TAKES VERY LITTLE TO MAKE JEFF HAPPY`, `example caption3`, …, `last example caption`

**EXPECTED OUTPUT:**

Caption: `MUTT AND JEFF–  IT TAKES VERY LITTLE TO MAKE JEFF HAPPY`

# Data

Data were collected from the Chronicling America dataset and incorporated into the Challenging America project. The test dataset is created from data, which was not previously presented in any Challenging America project. Therefore participants are allowed to use any data from the Challenging America project, but not Chronicling America (as the Chronicling America project site contains test data).

Other Challenging America challenges, which may be useful:
- https://gonito.csi.wmi.amu.edu.pl/challenge/challenging-america-geo-prediction
- https://gonito.csi.wmi.amu.edu.pl/challenge/challenging-america-word-gap-prediction
- https://gonito.csi.wmi.amu.edu.pl/challenge/challenging-america-year-prediction



The dataset is created in the following manner. Pictures and captions are extracted from the newspapers by a human annotator (max. one picture per site).

Then, the picture and caption are separated, so the picture does not contain a caption. The caption is typed by a human annotator and kept as golden truth. Newspaper date is taken from newspaper metadata.

All the data is separated into 3 datasets: training (train), development (dev-0), and test (test-A). The newspaper edition does not overlap between these datasets. The exact procedure for generating Challenging America challenges is given in [3].

The final score is calculated only on part of the data released as final test data released on May 17th., not including test data released on Feb 13th.

# Evaluation

## Metric

Metric is Mean Reciprocal Rank ( https://en.wikipedia.org/wiki/Mean_reciprocal_rank ). For the train and development dataset participants are encouraged to use geval evaluation tool, which usage is explained in “HOW TO”.

# Submissions

For a given image id and newspaper date timestamp, participants are expected to return a list of proposed captions sorted descending by probability. Though, always only one caption is relevant.

**In.tsv:**

The first column in the in.tsv dataset is a picture id. The second column in date timestamp in format YYYYMMDD.

**Out.tsv:**

For each row in the in.tsv file, there should be a corresponding list of caption ids sorted from the most probable to the least probable. The ids should be separated by a tab.

Solutions should be submitted to gonito platform.


In order to be included in the final ranking the participants are expected to provide the report that describes their solution. The reports should conform to the requirements specified in the report.tex template and should not exceed 4 pages.

# Rules

1. Participants are allowed to use any publicly available pre-trained model.
2. Participants are allowed to use any publicly available data, except for data from the Chronicling America https://chroniclingamerica.loc.gov/ . Using any data available in Challenging America is allowed.
3. It is allowed to use the dev set for the model training.
4. Manual labeling is forbidden.
5. Solutions should be submitted by Gonito platform.
6. Max. 5 solutions per day are allowed.
7. The best scoring solution on the leaderboard on test data is the winning one.
8. Teams may consist of one or more people. There is no restriction on the size of the team. Only one team representative should submit the teams' solution to the platform.
9. If the solution submitted by two different teams is found to be the same, the one who submitted earlier would be ranked higher.

# Special session ad FedCSIS 2023
