Goal event detection in soccer videos via collaborative multimodal analysis
Detecting semantic events in sports video is crucial for video indexing and retrieval. Most existing works have exclusively relied on video content features, namely, directly available and extractable data from the visual and/or aural channels. Sole reliance on such data however, can be problematic due to the high-level semantic nature of video and the difficulty to properly align detected events with their exact time of occurrences. This paper proposes a framework for soccer goal event detection through collaborative analysis of multimodal features. Unlike previous approaches, the visual and aural contents are not directly scrutinized. Instead, an external textual source (i.e., minute-by-minute reports from sports websites) is used to initially localize the event search space. This step is vital as the event search space can significantly be reduced. This also makes further visual and aural analysis more efficient since excessive and unnecessary non-eventful segments are discarded, culminating in the accurate identification of the actual goal event segment. Experiments conducted on thirteen soccer matches are very promising with high accuracy rates being reported
Survey of the State of the Art in Natural Language Generation: Core tasks, applications and evaluation
This paper surveys the current state of the art in Natural Language
Generation (NLG), defined as the task of generating text or speech from
non-linguistic input. A survey of NLG is timely in view of the changes that the
field has undergone over the past decade or so, especially in relation to new
(usually data-driven) methods, as well as new applications of NLG technology.
This survey therefore aims to (a) give an up-to-date synthesis of research on
the core tasks in NLG and the architectures adopted in which such tasks are
organised; (b) highlight a number of relatively recent research topics that
have arisen partly as a result of growing synergies between NLG and other areas
of artificial intelligence; (c) draw attention to the challenges in NLG
evaluation, relating them to similar challenges faced in other areas of Natural
Language Processing, with an emphasis on different evaluation methods and the
relationships between them.Comment: Published in Journal of AI Research (JAIR), volume 61, pp 75-170. 118

Soccer on Social Media
In the era of digitalization, social media has become an integral part of our
lives, serving as a significant hub for individuals and businesses to share
information, communicate, and engage. This is also the case for professional
sports, where leagues, clubs and players are using social media to reach out to
their fans. In this respect, a huge amount of time is spent curating multimedia
content for various social media platforms and their target users. With the
emergence of Artificial Intelligence (AI), AI-based tools for automating
content generation and enhancing user experiences on social media have become
widely popular. However, to effectively utilize such tools, it is imperative to
comprehend the demographics and preferences of users on different platforms,
understand how content providers post information in these channels, and how
different types of multimedia are consumed by audiences. This report presents
an analysis of social media platforms, in terms of demographics, supported
multimedia modalities, and distinct features and specifications for different
modalities, followed by a comparative case study of select European soccer
leagues and teams, in terms of their social media practices. Through this
analysis, we demonstrate that social media, while being very important for and
widely used by supporters from all ages, also requires a fine-tuned effort on
the part of soccer professionals, in order to elevate fan experiences and
foster engagement
Automatic Summarization of Soccer Highlights Using Audio-visual Descriptors
Automatic summarization generation of sports video content has been object of
great interest for many years. Although semantic descriptions techniques have
been proposed, many of the approaches still rely on low-level video descriptors
that render quite limited results due to the complexity of the problem and to
the low capability of the descriptors to represent semantic content. In this
paper, a new approach for automatic highlights summarization generation of
soccer videos using audio-visual descriptors is presented. The approach is
based on the segmentation of the video sequence into shots that will be further
analyzed to determine its relevance and interest. Of special interest in the
approach is the use of the audio information that provides additional
robustness to the overall performance of the summarization system. For every
video shot a set of low and mid level audio-visual descriptors are computed and
lately adequately combined in order to obtain different relevance measures
based on empirical knowledge rules. The final summary is generated by selecting
those shots with highest interest according to the specifications of the user
and the results of relevance measures. A variety of results are presented with
real soccer video sequences that prove the validity of the approach
