The Role of Metadata in Information Retrieval: An Annotated Bibliography Name:

Purpose This research aims to identify users' goals and strategies whensearching for podcasts and their impact on the design of podcast retrieval technology. Inparticular, the paper seeks to explore the potential to address user goals with indexingbased on podcast metadata and automatic speech recognition (ASR) transcripts.Design/methodology/approach The paper conducted a user study to obtain anoverview of podcast search behaviour and goals, using a multi-method approach of anonline survey, a diary study, and contextual interviews. In a subsequent podcastretrieval experiment, the paper investigated the retrieval performance of the two choicesof indexing features for search goals identified during the study.Findings The paper found that study participants used a variety of search strategies,partially influenced by available tools and their perceptions of these tools. Furthermorethe experimental results revealed that retrieval using ASR transcripts performedsignificantly better than metadata-based searching. However, a detailed result analysissuggested that the efficacy of the indexing methods was search-goal dependent.Research limitations/implications The research constitutes a step towards a futureframework for investigating user needs and addressing them in an experimental set-up.It was primarily qualitative and exploratory in nature.Practical implications Podcast search engines require evidence about suitableindexing methods in order to make an informed decision concerning whether it is worththe resources to generate speech recognition transcripts.Originality/value Systematic studies of podcast searching have not previously beenreported. Investigations of this kind hold the potential to optimise podcast retrieval in thelong term.Annotation: Retrieval technologies of podcast materials require suitable indexingmethods that addresses user needs. A useful part of the text suggests that findings ofthe study indicated that the user retrieval was more effective using automatic speechrecorder (ASR) transcripts rather than metadata based search.Search Strategy: Having used the afore-mentioned keywords and still wanting to get aspecific article on how metadata can affect how we access our information, I consultedthe thesaurus of the database and used controlled vocabulary like “metadata andinformation retrieval”. This phrase provided me with excellent resources not just in theWeb of Science interface from which this article was retrieved but from Dialog and mysecond search through LISTA.Database: Web of Science interface.Method of Searching: Controlled VocabularySearch String: “Metadata and Information retrieval”.
