Relevance Criteria when Searching and Evaluating Online Video for Informational Use

Dewitt-Miller, Erin 05 1900 (has links)
Relevance is a core concept in the field of Information Science and a common term in everyday vernacular that generally refers to the usefulness of information. However, relevance has not been sufficiently or consistently defined or explored in the information science literature. Relevance criteria are the factors that information users employ when determining whether information they encounter is relevant. Identifying relevance criteria is a crucial step to understanding relevance. Relevance criteria employed with newer information formats like online video are especially important to study. Online video is now widespread, and people are increasingly likely to rely on video for information. This study identifies relevance criteria employed during relevance assessments of online video through a explanatory sequential mixed-methods study of frequent online video users including students, faculty, librarians, and video professionals. Methods included an online survey and interviews.

The Effect of Personality Type on the Use of Relevance Criteria for Purposes of Selecting Information Sources.

Sims, Dale B. 12 1900 (has links)
Even though information scientists generally recognize that relevance judgments are multidimensional and dynamic, there is still discussion and debate regarding the degree to which certain internal (cognition, personality) and external (situation, social relationships) factors affect the use of criteria in reaching those judgments. Much of the debate centers on the relationship of those factors to the criteria and reliable methods for measuring those relationships. This study researched the use of relevance criteria to select an information source by undergraduate students whose task it is to create a course schedule for a semester. During registration periods, when creating their semester schedules, students filled out a two-part questionnaire. After completion of the questionnaire the students completed a Myers-Briggs Type Indicator instrument in order to determine their personality type. Data was analyzed using one-way ANOVAS and Chi-Square. A positive correlation exists between personality type as expressed by the MBTI and the information source selected as most important by the subject. A correlation also exists between personality type and relevance criteria use. The correlation is stronger for some criteria than for others. Therefore, one can expect personality type to have an effect on the use of relevance criteria while selecting information sources.

Partimos da premissa teórica de que relevância é mensurável e adotamos o princípio metodológico de que uma maior freqüência lexical encontra-se hipoteticamente associada a um maior peso relativo e relevância conceituais dentro de um conjunto de termos , aplicando-o na análise de conteúdo de 305 textos de quatro agências de notícia transnacionais a francesa France Presse (AFP), a americana Associated Press (AP), a espanhola EFE e a britânica/canadense Reuters em duas eleições presidenciais brasileiras. Neste corpus, coletado via telex, em 1989, e na internet, em 2010, identificamos os tipos de termo usados pelas quatro agências em função adjetiva antes, depois e em substituição ao nome dos quatro principais candidatos em cada eleição, mapeamos os esquemas de classificação política de cada uma e comparamos os critérios de relevância aplicados nos dois momentos, em busca de regularidades e discrepâncias que corroborassem, ou não, a hipótese de que agências de notícia transnacionais recorrem a esquemas de classificação próprios baseados numa tipologia comum de termos, cuja frequência no corpus revela os critérios de relevância de cada uma. Com base nos resultados, concluímos que os critérios de relevância das agências pesquisadas são semelhantes em diversos aspectos aos critérios adotados por usuários de sistemas de informação ao inferirem relevância em processos de busca
