TL;DR: The seeding algorithm is introduced and seeding strategies for identifying initial concepts in text volumes, such as books, that are stored in a digital library are explored.
Abstract: and phrases in a text, for which we use an automatically generated Concept-in-Context (CiC) network. Words and phrases rarely belong to a single concept; disambiguation in Capisco relies on interplay between words that are in close vicinity in the text. Starting the disambiguation is a seeding process, that identifies the first concepts, which then form the context for further disambiguation steps. This paper introduces the seeding algorithm and explores seeding strategies for identifying these initial concepts in text volumes, such as books, that are stored in a digital library.

TL;DR: The HTRC's involvement with the NOVEL(TM) text mining project and the Single Interface for Music Score Searching and Analysis project, both funded by the SSHRC Partnership Grant programme, will be introduced.
Abstract: This lecture provides an update on the recent developments and activities of the HathiTrust Research Center (HTRC) The HTRC is the research arm of the HathiTrust, an online repository dedicated to the provision of access to a comprehensive body of published works for scholarship and education The HathiTrust is a partnership of over 100 major research institutions and libraries working to ensure that the cultural record is preserved and accessible long into the future Membership is open to institutions worldwide Over 131 million volumes (47 billion pages) have been ingested into the HathiTrust digital archive from sources including Google Books, member university libraries, the Internet Archive, and numerous private collections The HTRC is dedicated to facilitating scholarship by enabling analytic access to the corpus, developing research tools, fostering research projects and communities, and providing additional resources such as enhanced metadata and indices that will assist scholars to more easily exploit the HathiTrust materials This talk will outline the mission, goals and structure of the HTRC It will also provide an overview of recent work being conducted on a range of projects, partnerships and initiatives Projects include Workset Creation for Scholarly Analysis project (WCSA, funded by the Andrew W Mellon Foundation) and the HathiTrust + Bookworm project (HT+BW, funded by the National Endowment for the Humanities) HTRC's involvement with the NOVEL(TM) text mining project and the Single Interface for Music Score Searching and Analysis (SIMSSA) project, both funded by the SSHRC Partnership Grant programme, will be introduced The HTRC's new feature extraction and Data Capsule initiatives, part of its ongoing work its ongoing efforts to enable the non-consumptive analyses of the approximately 8 million volumes under copyright restrictions will also be discussed The talk will conclude with some suggestions on how the non-consumptive research model might be improved upon and possibly extended beyond the HathiTrust context

TL;DR: In this article, the results from a series of network analyses examining how synthetic biology ethics is evolving are presented. But the results are limited to 802 institutions and 2,179 authors and suggest that the fields' social structure has become democratized at the individual level but remains dominated by a handful of institutions at the organizational level.
Abstract: Although synthetic biology is now an established field, ethical reflection surrounding it has only recently become a subject of sustained scientific inquiry. This poster displays the results from a series of network analyses examining how synthetic biology ethics is evolving. The studies gather ethics articles from 802 institutions and 2,179 authors and suggest that the fields' social structure has become democratized at the individual level but remains dominated by a handful of institutions at the organizational level.

TL;DR: This poster includes instances of the kinds of exploration HT+Bookworm made possible for students, as well as aiding in the indication of the points in time at which, for each class, the word entered widespread usage.
Abstract: ion of distant reading and the discovery of specific texts that they can then investigate further through close reading. Our poster includes instances of the kinds of exploration HT+Bookworm made possible for students. An example follows. The concept of “fidelity” (an important word to explore in connection with translation studies, a topic of the classes) shows different characteristics when explored in English (in which the concept maps onto the two words “fidelity” and “faithfulness”) and in Spanish (where the concept maps onto the single word “fidelidad”). Investigating the occurrence of the word by LoC category allows students to explore hypotheses such as whether the greater strength, historically speaking, of religious tradition in the Spanish-speaking world in comparison with the Anglophone world affects the relative prevalence of this word in different domains of use. Another example is a stacked area chart for a word of a kind for which HT+Bookworm helps provide an understanding of the word’s differentiated meanings in different use categories (for example, in the case of the word “depression”, in the use category of psychology and medicine versus that of economics). HT+Bookworm accomplishes this by abstracting separately across different LoC classes, while aiding in the indication of the points in time at which, for each class, the word entered widespread usage.

TL;DR: A theory of expectation is used to explain how music evokes various emotions for readers interested in cognitive science and evolutionary psychology as well as music as mentioned in this paper, which can be found in the book "Sweet Anticipation".
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.
