In this paper, we describe two aspects of a study we conducted of faceted search in an online public access library catalog (OPAC). First, we describe how we used log data from a university OPAC to develop a set of grounded tasks. Then, we describe our use of eye-tracking in a controlled laboratory setting to examine user behaviors performing the grounded tasks. We discuss the challenges we enc...

Using a 30-item multiple choice type test, this investigation dwelt on the ability of college students to recognize terms and concepts used by librarians. A total of 447 respondents representing the fields of education, nutrition, food technology, tourism and hotel and restaurant management took part in this investigation. Data were gathered through robotfotos and an inventory of commonly used ...

The vast majority of research output is grey; white (peer reviewed scholarly publications) forms a minor proportion. Historically, grey material was generated and used within an organisation. However, in recent years some researchrelevant grey material is being made openly available. Among grey outputs, research datasets are the largest proportion by volume and increasingly these are being made...

BDB is developed atin the Institute of Astronomy RAS, and contains information on physical and positional parameters of binary stars, belonging to various observational types: visual, spectroscopic, eclipsing, etc. Problems of information aggregation on binaries of various types binaries (obtained from heterogeneous sources of data astronomical catalogues and surveys) aggregation in a uniquefie...

In open virtual communities, thematic groups promote mutual cooperation among their members in order to reach specific targets. To this purpose, users share portions of their knowledge in a reciprocal understandable manner. For this aim, personal software agents are able to assist users by encoding personal information about preferences and goals into suitable profiles. In this work we present ...

BiOnIC is a catalog of aggregated statistics of user clicks, queries, and reuse counts for access to over 200 biomedical ontologies. BiOnIC also provides anonymized sequences of classes accessed by users over a period of four years. To generate the statistics, we processed the access logs of BioPortal, a large open biomedical ontology repository. We publish the BiOnIC data using DCAT and SKOS m...

Firms often search enthusiastically for distinguishing traits that they may use to price discriminate between segments. Yet there are occasions in which firms forgo the opportunity to price discriminate and instead charge a single price. Traditional explanations for why retailers forgo the opportunity to price discriminate focus on the cost of discriminating, including operational costs, explic...

art papers : art gallery 181 ABSTRACT The interface can be modeled as a an ecosystem: connected, dynamic, and characterized by relationships. The model is predicated on a process of working with the interface as a border zone between heterogeneous systems of representation. This paper uses sensation, embodiment, and semiotics to initiate this process, by addressing the range of systems of repre...

Over the past 10 years mutations in voltage-gated sodium channels (Na(v)s) have become closely associated with inheritable forms of epilepsy. One isoform in particular, Na(v)1.1 (gene symbol SCN1A), appears to be a superculprit, registering with more than 330 mutations to date. The associated phenotypes range from benign febrile seizures to extremely serious conditions, such as Dravet's syndrom...

A catalog of a class of (3, g) graphs for even girth g is introduced in this paper. A (k, g) graph is a graph with regular degree k and girth g. This catalog of (3, g) graphs for even girth g satisfying 6 ≤ g ≤ 16, has the following properties. Firstly, this catalog contains the smallest known (3, g) graphs. An appropriate class of trivalent graphs for this catalog has been identified, such tha...
