Event detection aims to discover news documents that report on the same event and arrange them under the same group. With the explosive growth of online news, there is a need for event detection to ...facilitate better navigation for users in news spaces. Existing works usually represent documents based on TF-IDF scheme and use a clustering algorithm for event detection. However, traditional TF-IDF vector representation suffers problems of high dimension and sparse semantics. In addition, with more news documents coming, IDF need to be incrementally updated. In this paper, we present a novel document representation method based on word embeddings, which reduces the dimension and alleviates the sparse semantics compared to TF-IDF, and thus improves the efficiency and accuracy. Based on the document representation, we propose an adaptive online clustering method for online news event detection, which improves both the precision and recall by using time slicing and event merging respectively. The resulted events are further improved by an adaptive post-processing step which can automatically detect noisy events and further process them. Experiments on standard and real-world datasets show that our proposed adaptive online event detection method significantly improves the performance of event detection in terms of both efficiency and accuracy compared to state-of-the-art methods.
Commoditization of marine resources has dramatically increased anthropogenic footprints on coastal and ocean systems, but the scale of these impacts remain unclear due to a pervasive lack of ...historical baselines. Through the analysis of historical newspapers, this paper explores changes in marine animals (vertebrates and invertebrates) targeted by historical fisheries in southern Brazil since the late 19th century. The investigation of historical newspaper archives revealed unprecedented information on catch composition, and perceived social and economic importance of key species over decades, predating official national-level landing records. We show that several economically and culturally important species have been under persistent fishing pressure at least since the first national-scale subsidies were introduced for commercial fisheries in Brazil in the late 19th and early 20th centuries. Our work expands the current knowledge on historical fish catch compositions in the southwestern Atlantic Ocean, while advocating for the integration of historical data in ocean sustainability initiatives.
In the current era of internet, information related to crime is scattered across many sources namely news media, social networks, blogs, and video repositories, etc. Crime reports published in online ...newspapers are often considered as reliable compared to crowdsourced data like social media and contain crime information not only in the form of unstructured text but also in the form of images. Given the volume and availability of crime-related information present in online newspapers, gathering and integrating crime entities from multiple modalities and representing them as a knowledge base in machine-readable form will be useful for any law enforcement agencies to analyze and prevent criminal activities. Extant research works to generate the crime knowledge base, does not address extraction of all non-redundant entities from text and image data present in multiple newspapers. Hence, this work proposes Crime Base, an entity relationship based system to extract and integrate crime related text and image data from online newspapers with a focus towards reducing duplicity and loss of information in the knowledge base. The proposed system uses a rule-based approach to extract the entities from text and image captions. The entities extracted from text data are correlated using contextual as-well-as semantic similarity measures and image entities are correlated using low-level and high-level image features. The proposed system also presents an integrated view of these entities and their relations in the form of a knowledge base using OWL. The system is tested for a collection of crime related articles from popular Indian online newspapers.

Changes to healthcare delivery organization that have occurred to protect people from the virus COVID-19 may have led to harmful consequences to pregnant women intensifying obstetric violence. ...Prevalence of obstetric violence in Ecuador is high with a range between 30 and 70% approximately.
This cross-sectional study was performed with the participation of 1298 women who answered EPREVO questionnaire from June 2021 to January 2022. Obstetrics characteristics' relationship before and during COVID-19 were examined using Fisher exact test.
From 1598 respondents, 1284 (80.4%) gave birth before March 2020 Most of the participants (73.6%; CI:73.59-73.61) experienced obstetric violence during childbirth. Vaginal examination, enemas and genital shaving, episiotomy and cesarean section decreased significantly as well as rooming with the baby during the pandemic. Half of the women did not breastfeed the baby in the first hour but there were not statistically significant differences between giving birth before or during the infection from COVID-19.
Levels of obstetric violence in Ecuador remains high but without major differences due to the COVID-19 pandemic, however some harmful medical practices considered as obstetric violence decreased but maybe to the fear to be infected by the virus.
This study identifies how three prominent Israeli online newspapers frame gay Members of Knesset (Israeli parliament) and cabinet ministers. 2019 was chosen since the number of gay MKs reached a ...historic milestone of representation. The study employed a mixed-methods design, combining descriptive statistics, based on a quantitative content analysis, with a thematic qualitative analysis. 1015 retrieved news items constituted the initial database. They were divided into two categories: “Gay relevant” (items explicitly referring to, or mentioning the politician’s sexual orientation); or “Gay irrelevant” (all other items), to thematically focus on the Gay relevant items (N = 159). Six themes were then identified: Novelty; LGBTQ Political Representation; Private Sphere; Homophobia; Community Recognition and Rights; and Incongruity. Findings revealed that elite newspaper coverage is similar to popular ones; cabinet ministers’ framing is more neutral compared to junior MKs; and liberal MKs are framed differently than conservative ones.
The paper aims at creating a bridge between media and migration studies and critical algorithm studies. By adopting a media ecological approach and a mutual shaping of technology and society ...perspective, in this paper, we explore the factors that lead, especially in Italy, to discriminant and stigmatizing image search results, related to specific groups of immigrants living in the country. We performed a content analysis of Google-Images search results with regard to the largest immigrant communities hosted in France, Germany, Italy, and the United Kingdom. Results show that the depiction of Romanian, Albanian, Moroccan, and Algerian immigrant communities on Google.it is flattened on a univocal stigmatized representation that shows them as criminals, which is not the case in other countries. Most of these stigmatizing images derive from local online newspapers, which questions the interplay between newsmaking choices and routines, and algorithms logics.
Through a quantitative content analysis (n = 878), this study examines and compares intermedia agenda-setting between right-wing alternative media outlets and mainstream online newspapers in the ...Scandinavian countries of Norway, Sweden and Denmark. Scholars have described the process of intermedia agenda-setting as an instrument used to uphold news norms within the journalistic community. Giving issue attention to another news media institution is considered a validation of the first news media's decision to report on a specific issue. This study, however, demonstrates how mainstream newspapers most often give issue attention to right-wing alternative media outlets in order to protect the boundaries of professional journalism as an institution as well as the limits of the debate from actors that are perceived as both journalistically and ideologically deviant. Regarding differences between the three countries, the findings reveal that the intermedia agenda-setting influence of alternative media outlets is higher in countries where populist actors are placed within "the sphere of legitimate controversy" (Norway and Denmark) than in countries where populist actors are banished to "the sphere of deviance" (Sweden).
Associated with numerous adverse health outcomes, body dissatisfaction in young men requires close examination. This study explores online accounts relating to male body image, including young men’s ...personal disclosures within one online newspaper article, and posts responding to this topic. Discursively informed thematic analysis indicated that non-disclosure was considered a problematic social expectation by the young men featured in the article. Also, reader posts variously constructed body dissatisfaction as a symptom of adolescence, a lack of self-care and an incapacity to capitalise on compensatory qualities. Our analysis suggests young men may welcome safe opportunities to critically discuss prevailing body image ideals.
