Lucene4IR: Developing information retrieval evaluation resources using Lucene

The workshop and hackathon on developing Information Retrieval Evaluation Resources using Lucene (L4IR) was held on the 8th and 9th of September, 2016 at the University of Strathclyde in Glasgow, UK and funded by the ESF Elias Network. The event featured three main elements: (i) a series of keynote and invited talks on industry, teaching and evaluation; (ii) planning, coding and hacking where a number of groups created modules and infrastructure to use Lucene to undertake TREC based evaluations; and (iii) a number of breakout groups discussing challenges, opportunities and problems in bridging the divide between academia and industry, and how we can use Lucene for teaching and learning Information Retrieval (IR). The event was composed of a mix and blend of academics, experts and students wanting to learn, share and create evaluation resources for the community. The hacking was intense and the discussions lively creating the basis of many useful tools but also raising numerous issues. It was clear that by adopting and contributing to most widely used and supported Open Source IR toolkit, there were many benefits for academics, students, researchers, developers and practitioners - providing a basis for stronger evaluation practices, increased reproducibility, more efficient knowledge transfer, greater collaboration between academia and industry, and shared teaching and training resources

Report on the Information Retrieval Festival (IRFest2017)

The Information Retrieval Festival took place in April 2017 in Glasgow. The focus of the workshop was to bring together IR researchers from the various Scottish universities and beyond in order to facilitate more awareness, increased interaction and reflection on the status of the field and its future. The program included an industry session, research talks, demos and posters as well as two keynotes. The first keynote was delivered by Prof. Jaana Kekalenien, who provided a historical, critical reflection of realism in Interactive Information Retrieval Experimentation, while the second keynote was delivered by Prof. Maarten de Rijke, who argued for more Artificial Intelligence usage in IR solutions and deployments. The workshop was followed by a "Tour de Scotland" where delegates were taken from Glasgow to Aberdeen for the European Conference in Information Retrieval (ECIR 2017

Adult participation in children’s word searches: on the use of prompting, hinting, and supplying a model

Although word searching in children is very common, very little is known about how adults support children in the turns following the child’s search behaviours, an important topic because of the social, educational and clinical implications. This study characterises, in detail, teachers’ use of prompting, hinting and supplying a model. From a classroom dataset of 53 instances, several distinctive patterns emerged. A prompted completion sequence is initiated by a ‘word retrieval elicitor’ (‘fishing’) and is interpreted as a request to complete the phrase. Non-verbal prompting is accomplished through a combination of gaze and gesture and, also, as a series of prompts. Hinting supplies a verbal clue, typically via a wh-question, or by specifying the nature of the repairable. In contrast, the strategies that supply a linguistic model include both embedded and exposed corrections and offers of candidates. A sequential relationship was found between prompting, hinting and supplying a model which has implications for how clinicians and teachers can foster self-repair

Word searches: on the use of verbal and non-verbal resources during classroom talk

Word finding difficulties in children are typically characterised by search behaviours such as silence, circumlocution, repetition and empty words. Yet, how children’s word searches are constructed (including gesture, gaze and prosody) and the actions accomplished during interaction have not yet been researched. In this study, eightyear- old Ciara is interacting with her teacher in the classroom. 37 segments containing word searches were analysed according to the procedures used by conversation analysts. Ciara’s interactional resources include co-ordinated deployment of syntax, pitch height and downward gaze during solitary searching that assist the enterprise of self-repair. Gaze shift towards the teacher signals a transition relevance place, thus constituting a direct invitation for her to participate in the search. Ciara’s interactional resources include semantic category labelling, phonological self-cuing and pronominal substitution that supply valuable linguistic information to the teacher and trigger production of the searched-for item. Recommendations for language teaching and therapy are presented

Upbeat and quirky with a bit of a build: Interpretive repertories in creative music search

Pre-existing commercial music is widely used to accom-pany moving images in films, TV commercials and com-puter games. This process is known as music synchronisa-tion. Professionals are employed by rights holders and film makers to perform creative music searches on large catalogues to find appropriate pieces of music for syn-chronisation. This paper discusses a Discourse Analysis of thirty interview texts related to the process. Coded ex-amples are presented and discussed. Four interpretive repertoires are identified: the Musical Repertoire, the Soundtrack Repertoire, the Business Repertoire and the Cultural Repertoire. These ways of talking about music are adopted by all of the community regardless of their interest as Music Owner or Music User. Music is shown to have multi-variate and sometimes conflicting meanings within this community which are dynamic and negotiated. This is related to a theoretical feedback model of communication and meaning making which proposes that Owners and Users employ their own and shared ways of talking and thinking about music and its context to determine musical meaning. The value to the music information retrieval community is to inform system design from a user information needs perspective

Growing up Overseas: Perceptions of Second Language Attrition and Retrieval Amongst Expatriate Children in India

This study involves expatriate children whose first language (L1) is English and who learned Hindi as their second language (L2) while their parents worked in India. The purpose of the study was to investigate the linguistic experiences of the children after they had left India, particularly experiences with L2 attrition. Through semi-structured interviews, subjects shared their stories of L2 acquisition and attrition. Common experiences which contributed to the attrition of the L2 included periods of non-use of the L2, social responses to the use of the L2, the lack of development of Hindi literacy and subjects’ attitude toward using the L2. Some of the subjects were able to retrieve the L2 on return trips to India and an examination is made of their perceptions of what supported this retrieval process. These include exposure to the “environment” of India and personal motivation. The conclusion provides questions and suggestions for further research to contribute to a better understanding of the linguistic experiences of expatriate children. Cette étude concerne les enfants expatriés de langue maternelle anglaise qui ont appris le hindi comme deuxième langue (L2) alors que leurs parents travaillaient en Inde. Le but de cette étude était d’enquêter sur les pratiques linguistiques usuelles de ces enfants une fois qu’ils avaient quitté l’Inde, avec un accent particulier sur l’érosion de la L2. Au cours d’entrevues semistructurées, les participants ont raconté comment ils ont acquis et oublié la deuxième langue (L2). Les facteurs usuels d’érosion de la L2 comprennent des périodes de non utilisation de la L2, les réactions sociales à l’utilisation de la L2, le manque de développement de l’alphabétisation des participants en hindi, et leur attitude envers l’usage de la L2. Certains des participants ont pu récupérer la langue suite à un retour en Inde; ils attribuent cette récupération à plusieurs facteurs, notamment l’exposition à un environnement indien et la motivation personnelle. La conclusion formule des questions et des suggestions pour mener d’autres recherches afin de mieux comprendre les expériences linguistiques des enfants expatriés
