Exploiting graph‐based data to realize new functionalities for scholar‐built worksets

Abstract: In this poster, we describe how the HathiTrust Research Center (HTRC) is developing a graph‐based approach to representing scholar‐built worksets in the HTRC's research workflows. The use of named graphs to express relationships among worksets, workset items (volumes and pages) and relevant external resources and to manage ownership, version control and access to worksets aligns well with HTRC's non‐consumptive research architecture. In addition to managing scholars' research collections, HTRC workset graphs also provide a means to link individual workset items to descriptive metadata and allows scholars to annotate their worksets and the items in them.

A "do-it-yourself" evaluation service for music information retrieval systems

Abstract: 1. EXTENDED ABSTRACT This demonstration presents the Do-It-Yourself (DIY) web service of the Music Information Retrieval Evaluation eXchange (MIREX). As TREC does for text retrieval, MIREX provides standardized datasets and evaluation frameworks to evaluate Music Information Retrieval (MIR) systems and algorithms [1]. However, unlike TREC where participants are given the datasets and execute their code locally, MIREX data sets cannot be distributed due to copyright restrictions. In previous years, MIREX participants submitted systems to the International Music Information Retrieval Systems Evaluation Laboratory (IMIRSEL), where they were manually executed, and evaluated.

MEDDLEing with Digital Library Searches: Surmounting User Model and System Misalignments through Lightweight Bespoke Proxying

Abstract: We document how surprisingly easy it is for user misconceptions to arise when using digital library search interfaces, and the significant unseen impact this can have on the user's interpretation of search results. Further, we detail a bespoke proxying technique we have devised called Meddle -- for ModifiED Digital Library Environment -- which is a lightweight agile technique that helps address identified pitfalls in a DL search interface that operates independently of the originating digital library.

Using the HTRC data capsule model to promote reuse and evolution of experimental analysis of digital library data: a case study of topic modeling

Abstract: We report on a case-study to independently reproduce the work given in a publicly available blog on how to develop a topic model sourced from a collection of texts, where both the data set and source code used are readily available. More specifically, we detail the steps necessary---and the challenges that had to be overcome---to replicate the work using the HathiTrust Research Center's virtual machine Data Capsule platform. From this we make recommendations for authors to follow, based on the lessons learned. We also show that the Data Capsule model can be put to work in a way that is of benefit to those interested in supporting computational reproducibility within their organizations.

Content-based multimedia information retrieval: State of the art and challenges

Abstract: Extending beyond the boundaries of science, art, and culture, content-based multimedia information retrieval provides new paradigms and methods for searching through the myriad variety of media all over the world. This survey reviews 100p recent articles on content-based multimedia information retrieval and discusses their role in current research directions which include browsing and search paradigms, user studies, affective computing, learning, semantic queries, new features and media types, high performance indexing, and evaluation techniques. Based on the current state of the art, we discuss the major challenges for the future.

Invisible colleges : diffusion of knowledge in scientific communities

Abstract: No wonder you activities are, reading will be always needed. It is not only to fulfil the duties that you need to finish in deadline time. Reading will encourage your mind and thoughts. Of course, reading will greatly develop your experiences about everything. Reading invisible colleges diffusion of knowledge in scientific communities is also a way as one of the collective books that gives many advantages. The advantages are not only for you, but for the other peoples with those meaningful benefits.

Sweet Anticipation: Music and the Psychology of Expectation

Abstract: A theory of expectations is used to explain how music evokes various emotions for readers interested in cognitive science and evolutionary psychology as well as music. The psychological theory of expectation that David Huron proposes in "Sweet Anticipation" grew out of experimental efforts to understand how music evokes emotions. These efforts evolved into a general theory of expectation that will prove informative to readers interested in cognitive science and evolutionary psychology as well as those interested in music. The book describes a set of psychological mechanisms and illustrates how these mechanisms work in the case of music. All examples of notated music can be heard on the Web. Huron proposes that emotions evoked by expectation involve five functionally distinct response systems: reactive responses (which engage defensive reflexes); tension responses (where uncertainty leads to stress); predictive responses (which reward accurate prediction); imaginative responses (which facilitate deferred gratification); and appraisal responses (which occur after conscious thought is engaged). For real-world events, these five response systems typically produce a complex mixture of feelings. The book identifies some of the aesthetic possibilities afforded by expectation, and shows how common musical devices (such as syncopation, cadence, meter, tonality, and climax) exploit the psychological opportunities. The theory also provides new insights into the physiological psychology of awe, laughter, and "spine-tingling chills." Huron traces the psychology of expectations from the patterns of the physical/cultural world through imperfectly learned heuristics used to predict that world to the phenomenal qualia experienced by those who apprehend the world.
