As a way of understanding users' information needs for image, this study aims to explore unsuccessful image search questions in context of a social Q&A service. To achieve this purpose, 41 unsuccessful image seeking questions in Yahoo! Answers were explored. 41 questions for image were analyzed in terms of information needs types and image attributes. The findings of this preliminary study show...
In this era of overabundant information and content, people increasingly rely on recommender systems to identify those information items that best meet their needs and interests. Movie recommender systems, like the one used by Netflix, attempt to predict which films a given person will enjoy watching. While these systems help single individuals making decisions, they provide limited support for groups...
The Flickr Feasibility Study investigated the roles and processes required for a digital collection aggregator to facilitate participation of cultural heritage institutions in Web 2.0 communities. The results demonstrate that providing this service for museums, libraries, and archives can be a natural extension of aggregation activities. While the role is complicated by the varying requirements of...
Sharing and tagging images is an activity that is very popular among web users. This has lead to the creation of Internet services such as Flickr that allow users to post their own pictures and tag them with the purpose of sharing them with friends and displaying their work in a public forum. This poster presents the results of a study conducted in the framework of the Interactive Image Retrieval...
This demonstration will showcase a prototype Mobile application we built for accessing the library catalog at the University of Texas. The demonstration complements our corresponding short paper, “Mobile Phone Search for Library Catalogs”, also appearing at ASIS&T 2010. In particular, we will provide attendees a hands‐on experience seeing and using our interface, as well as an opportunity to discuss...
Digital libraries should improve their support of social interactions, especially the building of communities around and within themselves, to integrate better with social groups and communities across boundaries. This poster reports on ongoing work that has developed an online survey instrument to measure support for community‐building activities in digital libraries. In a small pilot sample of users...
Current thesauri do not indicate how two related (RT) terms can be related. An enriched thesaurus by differentiating the RT relationship helps people understand how two RT terms can be related, and is expected to be a better retrieval aid by facilitating information needs clarification and query formulation.
This study was designed to document the state of open access (OA) in the biomedical field in 2009. PubMed was used to collect bibliographic data on target articles published in 2009. Google and PubMed were then used to establish the availability of free full‐text online versions for these articles. Articles were analyzed according to the type of OA to provide insight into the characteristics of OA...
This study investigated the retrieval effectiveness of tagging through experimental tests. We developed a test collection, a list of topics and corresponding relevance judgments using data collected from Pubmed and CiteULike. Two retrieval test runs were carried out, one without tags (baseline) and one with tags (tag run). General improvements in retrieval performance were observed from the tag run...
Blogs, and particularly newsblogs, are receiving increased attention for their role in uncovering important or underdeveloped aspects of news stories. This research was an attempt to explore relevance criteria as it applies to users of newsblogs. An anonymous online questionnaire presented individuals with a list of established user relevance criteria, ranking the importance of each characteristic...
This paper reports a study in progress on tag analysis of a social bookmarking site, which attempts to identify a syntagmatic semantic relation of user tags. Preliminary analysis divided the descriptive top tags into categories of content topic and comment, and the relation between them was inferred from the content analysis of the user note.
Our purpose is to present the rationale and results of a pilot study applying a meta‐theoretically derived approach to focus group or semi‐structured group interviewing as a means of obtaining deep data efficiently and dialogically. The project was designed to meet needs of both the senior author (a methodologist) and junior author (a librarian). The exemplar was undergraduate information seeking...
In this poster we describe a pilot study of searching social science literature for legacy corpora to evaluate text mining algorithms. The new emerging field of computational social science demands large amount of social science data to train and evaluate computational models. We argue that the legacy corpora that were annotated by social science researchers through traditional Qualitative Data Analysis...
Public library systems in New York State have been in existence since the 1950s. They have been providing services to individual public libraries by facilitating resource sharing among them and enhancing their capacity to provide quality services to users. The public does not always have knowledge of public library systems since they are not directly served by public library systems. Knowledge of...
This paper presents a study that took an interdisciplinary approach to investigating historians' information‐seeking behavior (ISB) during their historical research. The author reviewed the literature of library and information science, archival science, and history to compare their findings on historians' ISB to a model of social scientists' ISB developed by Lokman I. Meho and Helen R. Tibbo. The...
While Greenstone is a versatile tool for creating and managing digital collections, its interface is not well suited for senior users. As we age, our usability requirements for software change; the mismatch between interfaces designed for (and by) younger members of society and the interface usability requirements of the elderly can make software less usable for the elderly. This paper reports on...
Twitter is a fast growing real‐time social media tool. As Twitter evolves, more and more people are partaking in sharing what is happening around the world through various Twitter applications. Hashtag use has become a unique tagging convention to help associate Twitter messages with certain events or contexts. Prefixed by a # symbol with a keyword, a Twitter hashtag serves as a bottom‐up user‐proposed...
In this contribution we investigate the potential influence between assessors' perceived completion of their work task at hand and their actual assessment of usefulness of the retrieved information. The results indicate that the number of useful documents found by assessors does not influence their perception of task completion. Also, with the exception of full text records and across all document...
